+// One-shot script generation eval (`bashkit_generate`).
+//
+// Why: `bashkit_bash` is an agent loop; the model probes, sees errors and
+// retries, which hides how often its FIRST script fails on bashkit. Here the
+// model gets the task plus a fixed description of the sandbox, answers with ONE
+// bash script (no tools, no feedback), and bashkit runs it exactly once on a
+// fresh VFS built like the agent eval's (`agent::build_task_bash`). The
+// unchanged `expectations_scorer` then scores files/stdout/exit code.
+//
+// Decisions (see knowledge/operations/eval.md, "Generate Eval"):
+//   - One provider call with NO tools offered (providers omit `tools` when the
+//     list is empty), so the reply is plain text.
+//   - Extraction rule (`extract_script`): the first fenced block tagged
+//     `bash`/`sh`/`shell` (case-insensitive); else the first untagged fenced
+//     block; else the whole reply, trimmed. An unclosed fence (truncated reply)
+//     runs to the end of the text. Fenced blocks tagged with another language
+//     are never run.
+//   - Failure split: a provider/HTTP error or a broken starting state is an
+//     infra error (case scores N/A); an empty/absent script is a model failure
+//     scored 0 (the subject records an empty Snapshot and no files, so every
+//     check fails without touching the scorer); a script that errors, exits
+//     non-zero or times out is an ordinary scored run.
+//   - The script runs once via `bash.exec` under `SCRIPT_TIMEOUT`; a timeout
+//     records exit code 124 (coreutils `timeout` convention).
+//   - The task's `system` field is not used: the system prompt is the fixed,
+//     documented `GENERATE_SYSTEM_PROMPT` so every task sees the same sandbox
+//     description.

 ## 2026-10-09
 
+* **Test**: `bashkit_generate` eval (`just eval-generate`): one-shot script generation, 15 tasks (`basic`/`hard`). The model gets the task and a fixed sandbox description, answers with one bash script (no tools, no feedback), bashkit runs it once on `build_task_bash` and the shared expectations scorer scores it. Extraction: first `bash`/`sh`/`shell` fence, else first untagged fence, else the whole reply; no script scores 0, provider errors are N/A. Providers omit `tools` when none are offered. References pass in `cargo test -p bashkit-eval` and under real bash 5.2; `true` fails every task. See operations/eval "Generate Eval".
 * **Fix**: `jq -n` reported invalid JSON on stdin even when the filter never read it (`printf x | jq -n 1` printed `1` plus an `invalid JSON` error and exited 5). With `-n`, a stdin parse error is now reported only once `input`/`inputs` read past the last valid value, like jq 1.7 (`printf '1 x' | jq -n input` prints `1`, status 0).
 * **Test**: `bashkit_hard` eval (`just eval-hard`): 10 tasks written after `bashkit_bash` saturated (55/58 for top models), 25-turn budget, 9 categories: interacting bugs revealed one test at a time, quoting/glob/leading-dash file names, masked `set -euo pipefail` failures, trap/exit-code contracts, Makefile prerequisites checked with `make -q`, a rename that must spare lookalikes and frozen messages, and golden reports (CSV/TSV reconciliation, nearest-rank p95 over a generated log, jq rollups, deterministic topological order). New check `file_equals` (whole-file golden output). Reference solutions replay in `cargo test -p bashkit-eval` alongside the repo set (`reference.rs` now iterates both datasets) and were also checked under real bash. See operations/eval "Hard Eval".
 * **Fix**: gaps found by the `bashkit_hard` eval references. A child `bash script` / `bash -c` started in an `if`/`||`/`&&`/`!` context ran with `set -e` disabled (the caller's condition depth leaked into the child), so `if bash test.sh` never saw `test.sh` fail; the child now starts outside any condition, like a new process. `dirname -- PATH` treats `--` as end of options (it printed `.` for it); `ls -A` is accepted (same listing as `-a`, which never shows `.`/`..`); `stat -c %Y` prints the mtime in epoch seconds (it printed `%Y`).

+## Generate Eval (`bashkit_generate`)
+
+Added 2026-10-09. `bashkit_bash` is an agent loop: the model probes, sees
+errors and retries, which hides how often its **first** script fails on
+bashkit. `bashkit_generate` measures one-shot generation. Decision: a separate
+eval because scoring differs (one script, one run, no feedback); otherwise
+evals stay one tagged dataset.
+
+- **Subject** (`src/generate.rs`, `generate_subject`): one provider call with
+  no tools offered (the providers omit `tools` when the list is empty, which
+  Chat Completions requires), under the fixed `GENERATE_SYSTEM_PROMPT`
+  (bashkit virtual bash, the builtin set incl. coreutils/awk/sed/jq/grep/find,
+  HOME=/home/eval, no network, no python/node/perl unless stated, answer as
+  one ```` ```bash ```` block). The task's `system` field is not used. The
+  script runs once via `bash.exec` on `build_task_bash(task)` (same starting
+  state as the agent eval: files, git, `setup`), bounded by `SCRIPT_TIMEOUT`
+  (60 s; a timeout records exit 124).
+- **Extraction rule** (`extract_script`): the first fenced block tagged
+  `bash`/`sh`/`shell` (case-insensitive); else the first untagged fenced
+  block; else, when the reply has no fence at all, the whole reply trimmed.
+  Blocks in other languages are never run; an unclosed fence (truncated
+  reply) runs to the end of the text; a closing fence must start a line.
+- **Scoring**: the transcript has the same shape as `bash_subject`'s (one
+  `ToolOutput` in the `Snapshot`, expectation-relevant VFS files), so the
+  shared `expectations_scorer` scores it unchanged.
+- **Failure split**: provider/HTTP error or a failing `setup` = infra error
+  (N/A). No script (empty reply, empty block, only non-shell fences) = model
+  failure: empty snapshot and no files, so every check fails and the score
+  is 0. A script that errors, exits non-zero or times out is scored normally.
+- **Metrics**: `script_found`, `extracted` (1 fenced / 0 raw), `script_bytes`,
+  `exit_code`, `timed_out`, `generate_ms`, `exec_ms`, plus usage tokens;
+  `transcript.metadata["generate"]` carries `extraction` and `timed_out`.
+
+Dataset `data/generate-tasks.jsonl` (same `EvalTask` schema, `mode:
+"generate"`, difficulty `basic`/`hard` as tags) is validated by its own test
+(`generate::tests::dataset_is_valid`), not the `bashkit_bash` tag test.
+Every path under `/home/eval`; prompts show each starting file verbatim
+because the model cannot look. Reference scripts in
+`data/generate-solutions.jsonl` (one `steps` entry each) run in `cargo test
+-p bashkit-eval` through the subject's own run path and must pass every
+check; the do-nothing script `true` must fail every task. All 15 references
+also pass under real bash 5.2.21 (jq 1.7, mawk 1.3.4) with `/home/eval`
+rewritten to a temp dir, and `true` fails each there too.
+
+| Task | Difficulty | What it exercises |
+|------|------------|-------------------|
+| `gen_log_status_report` | basic | status-code histogram and 5xx list from an access log |
+| `gen_log_rotate` | hard | numbered rotation with a keep count, gaps, lookalike `app.log.old` |
+| `gen_csv_to_jsonl` | basic | CSV to typed JSON Lines, last line without newline |

+| `gen_semver_bump` | hard | semver bump from conventional changes (9 -> 10), changelog insert |
+
+Building the references found two bashkit gaps. Fixed: `jq -n` failed on
+non-JSON stdin it never reads (`jq -cn ...` inside `while read; done <
+file.csv`); jq 1.7 reads stdin lazily under `-n`, now only a pulled parse
+error counts. Open (the reference avoids it): a double-quoted pattern with
+`\$` inside `${var//pattern/repl}` is not unescaped (`"${c//"\${K}"/V}"`
+replaces nothing; bash replaces `${K}`), and the unquoted form
+`${c//\${K\}/V}` is a parse error.

Subject: [PATCH 03/14] fix(sqlite): persist databases in rollback-journal mode

Turso writes WAL-mode headers (bytes 18/19 = 2). The Memory backend
persists only the checkpointed main file, so the image is a valid
legacy-mode database; mark it as one. CPython's sqlite3 module in the
WASI guest has no WAL and rejected the file as "file is not a
database", so python3 could not open a db written by sqlite3.

Also record known sqlite3 shell divergences (csv quoting, exit codes,
.import) found by the eval runtime tasks.

Subject: [PATCH 04/14] fix(interpreter): run a script's shebang interpreter
 when it is a builtin

An executable file with #!/usr/bin/env python3 (or #!/usr/bin/python3,
#!/usr/bin/awk -f) run by path or PATH lookup had its shebang stripped
and its body parsed as bash, so agent-built Python CLIs failed with a
parse error. A shebang naming a registered non-shell builtin now runs
that builtin with the script path as its argument (Linux semantics:
one optional argument; env -S splits). bash/sh, unknown interpreters
and shell-only builtins keep running the content as bash.

Adds CPython integration tests for shebang scripts and for python3
reading/writing a database made by the sqlite builtin.

Subject: [PATCH 05/14] feat(eval): add mode=runtime tasks with python3 and
 sqlite3

Every eval Bash now runs real CPython 3.14 (cpython feature) and the
sqlite builtin (sqlite feature, opt-in env set); the tool prompt the
model sees registers the same builtins, so it lists their hints instead
of "python/python3 not available". bashkit-replay uses the same
runtimes.

12 runtime tasks (tag runtime, just eval-runtime): python3 file
processing (CSV rollup, JSONL flatten, sessionization, encodings, TOML
render, a 12k-line log), a bash+python report script, sqlite3 (CSV load
+ report, a reusable migration file, python reading a sqlite3-built db)
and state across calls (a CLI on PATH, an idempotent ingester).

Tasks gain a hidden verify script, run after the agent in a fresh Bash
on the same filesystem; its output (/.eval/verify.out) is scored, so a
built tool is re-run on unseen input. Goldens come from the generator,
references pass in bashkit and against real python 3.13, sqlite3 3.45
and bash 5.2. The untouched-fixture test covers runtime tasks.

 ## Dataset
 
-58 hand-curated tasks in JSONL format across 15 categories: file_operations, text_processing, pipelines, scripting, data_transformation, error_recovery, system_info, archive_operations, json_processing, complex_tasks, code_search, environment, database_operations, config_management, build_simulation.
+One tagged JSONL dataset, `data/eval-tasks.jsonl`. Each task has a `mode`
+(`agent`: bash is the model's tool; `runtime`: bashkit is the execution
+runtime), a `difficulty` (`basic`, `repo`, `hard`) and an optional
+`max_turns`. Every eval `Bash` has sandboxed git, real CPython 3.14 as
+`python3` (`cpython` feature) and `sqlite3` (`sqlite` feature).
+
+- 58 basic agent tasks across 15 categories: file_operations, text_processing, pipelines, scripting, data_transformation, error_recovery, system_info, archive_operations, json_processing, complex_tasks, code_search, environment, database_operations, config_management, build_simulation.
+- 8 repo tasks (`repo_workflow`): a `setup` script builds a fixture git repo,
+  the model runs `make test`, fixes the bug, and commits (symlinks, PATH,
+  background jobs, jq, git).
+- 10 hard agent tasks written after the basic set saturated: interacting bugs
+  revealed one test at a time, quoting/glob/leading-dash file names, masked
+  `set -euo pipefail` failures, trap/exit-code contracts, Makefile dependency
+  graphs, a rename that must spare lookalikes and frozen messages, and
+  golden-output reports.
+- 12 runtime tasks: python3 file-processing scripts (CSV/JSONL/log/encoding/
+  TOML transforms with the stdlib), python3 + bash pipelines, sqlite3 (load CSV,
+  report queries, a reusable schema migration), and state across calls (build
+  a CLI or an idempotent ingester, use it, and have a hidden `verify` script
+  run it again on unseen input after the session).
+
+Reference solutions for every non-basic or runtime task live in
+`data/solutions.jsonl` and run in `cargo test -p bashkit-eval`, so every task
+stays solvable without an LLM and a do-nothing run must fail.
 
 Smoke test dataset (`data/smoke-test.jsonl`) has 3 tasks for quick verification.
 
-Repo workflow dataset (`data/repo-workflow.jsonl`, eval `bashkit_repo`) has 8
-multi-turn tasks: a `setup` script builds a fixture git repo, the model runs
-`make test`, fixes the bug, and commits (symlinks, PATH, background jobs, jq,
-git). Reference solutions in `data/repo-workflow-solutions.jsonl` run in
-`cargo test -p bashkit-eval`, so every task stays solvable without an LLM.

The sort is stable: equal keys keep their input order, also with --desc.\n- Output: CSV on stdout with the header row, '\\n' line endings, fields quoted only when they contain a comma, quote or newline.\n- If any option names a column not in the header, print `csvq: unknown column: NAME` to stderr, print nothing on stdout and exit 2.\n\nThen use csvq on /data/staff.csv to write /out/eng_top.csv (dept eng; columns name,salary; sorted by salary numerically, highest first) and /out/by_city.csv (columns city,name sorted by city).", "files": {"/data/staff.csv": "name,dept,city,salary\nAva,eng,Berlin,120000\nBen,ops,Lisbon,70000\nCara,eng,Austin,135000\nDev,eng,Berlin,99000\nEve,sales,Austin,80000\nFinn,eng,Lisbon,135000\nGia,ops,Berlin,\n"}, "verify": "export PATH=/home/eval/bin:$PATH\ncd /tmp\ncat > /tmp/v.csv <<'EOF'\nname,team,score,note\n\"Lopez, Ana\",red,10,ok\nBo,blue,9.5,\"said \"\"hi\"\"\"\nCy,red,n/a,a=b\nDi,red,10,\nEd,red,-2,a=b\n\"Fay\nLynn\",red,100,multi\nGil,blue,3,a=b\nEOF\ncsvq --where team=red --select name,score --sort score --numeric --desc /tmp/v.csv\ncsvq --sort note --desc v.csv\ncsvq --where note=a=b --where team=red --select score,name /tmp/v.csv\nout=$(csvq --select name,nope /tmp/v.csv); echo \"rc=$? out=${#out}\"", "expectations": [{"check": "file_equals:/out/eng_top.csv:name,salary\nCara,135000\nFinn,135000\nAva,120000\nDev,99000\n"}, {"check": "file_equals:/out/by_city.csv:city,name\nAustin,Cara\nAustin,Eve\nBerlin,Ava\nBerlin,Dev\nBerlin,Gia\nLisbon,Ben\nLisbon,Finn\n"}, {"check": "file_equals:/.eval/verify.out:name,score\n\"Fay\nLynn\",100\n\"Lopez, Ana\",10\nDi,10\nEd,-2\nCy,n/a\nname,team,score,note\nBo,blue,9.5,\"said \"\"hi\"\"\"\n\"Lopez, Ana\",red,10,ok\n\"Fay\nLynn\",red,100,multi\nCy,red,n/a,a=b\nEd,red,-2,a=b\nGil,blue,3,a=b\nDi,red,10,\nscore,name\nn/a,Cy\n-2,Ed\ncsvq: unknown column: nope\nrc=2 out=0\n"}]}

 ## 2026-10-09
 
 * **Test**: `bashkit_generate` eval (`just eval-generate`): one-shot script generation, 15 tasks (`basic`/`hard`). The model gets the task and a fixed sandbox description, answers with one bash script (no tools, no feedback), bashkit runs it once on `build_task_bash` and the shared expectations scorer scores it. Extraction: first `bash`/`sh`/`shell` fence, else first untagged fence, else the whole reply; no script scores 0, provider errors are N/A. Providers omit `tools` when none are offered. References pass in `cargo test -p bashkit-eval` and under real bash 5.2; `true` fails every task. See operations/eval "Generate Eval".
+* **Test**: `mode=runtime` eval tasks (`just eval-runtime`, tag `runtime` in `bashkit_bash`): 12 tasks where bashkit is the agent's execution runtime: python3 file-processing scripts (CSV, JSONL, logs, encodings, TOML), python3 + bash pipelines, sqlite3 (CSV load and reports, a reusable migration file), and state across calls (a CLI on PATH, an idempotent SQLite ingester). Every eval `Bash` now has real CPython (`cpython` feature) and sqlite (`sqlite` feature, opt-in env set), and the model's tool prompt lists them. Tasks gain a hidden `verify` script, run after the agent in a fresh `Bash` on the same filesystem, whose output is scored (`/.eval/verify.out`): it re-runs what the model built on unseen input. References pass in bashkit and against real python 3.13 / sqlite3 3.45 / bash 5.2. See operations/eval "Runtime Tasks".
+* **Fix**: gaps found by the runtime tasks. A script run by path or `PATH` whose shebang names a registered non-shell builtin (`#!/usr/bin/env python3`, `#!/usr/bin/awk -f`) now runs that builtin on the script path, as the kernel would; it was stripped and the Python ran as bash. The sqlite builtin persists databases in rollback-journal mode (header bytes 18/19 = 1): Turso writes WAL headers, which CPython's WASI SQLite (built without WAL) rejected as "file is not a database", so `python3` could not open a db made by `sqlite3`. Open: `printf '\x00'` drops NUL bytes; sqlite `csv` quoting and error exit codes differ from the sqlite3 shell (runtimes/sqlite-builtin "Output formatting").
 * **Fix**: `jq -n` reported invalid JSON on stdin even when the filter never read it (`printf x | jq -n 1` printed `1` plus an `invalid JSON` error and exited 5). With `-n`, a stdin parse error is now reported only once `input`/`inputs` read past the last valid value, like jq 1.7 (`printf '1 x' | jq -n input` prints `1`, status 0).
 * **Test**: `bashkit_hard` eval (`just eval-hard`): 10 tasks written after `bashkit_bash` saturated (55/58 for top models), 25-turn budget, 9 categories: interacting bugs revealed one test at a time, quoting/glob/leading-dash file names, masked `set -euo pipefail` failures, trap/exit-code contracts, Makefile prerequisites checked with `make -q`, a rename that must spare lookalikes and frozen messages, and golden reports (CSV/TSV reconciliation, nearest-rank p95 over a generated log, jq rollups, deterministic topological order). New check `file_equals` (whole-file golden output). Reference solutions replay in `cargo test -p bashkit-eval` alongside the repo set (`reference.rs` now iterates both datasets) and were also checked under real bash. See operations/eval "Hard Eval".
 * **Fix**: gaps found by the `bashkit_hard` eval references. A child `bash script` / `bash -c` started in an `if`/`||`/`&&`/`!` context ran with `set -e` disabled (the caller's condition depth leaked into the child), so `if bash test.sh` never saw `test.sh` fail; the child now starts outside any condition, like a new process. `dirname -- PATH` treats `--` as end of options (it printed `.` for it); `ls -A` is accepted (same listing as `-a`, which never shows `.`/`..`); `stat -c %Y` prints the mtime in epoch seconds (it printed `%Y`).

+## Runtime Tasks (`mode=runtime`)
+
+Added 2026-10-09. Bashkit's main use is agents running scripted logic inside
+it as a runtime, and the top priority for embedded python3 is agents
+processing files with scripts (see [CPython](../runtimes/cpython-wasm.md)).
+The agent tasks never exercised that: no python, no sqlite. Twelve
+`mode=runtime` tasks do, with the same subject/scorer, per-task `max_turns`
+(15 basic, 20-25 hard) and reference solutions.
+
+**Runtimes on for every task.** `with_eval_runtimes` enables CPython and
+sqlite in every eval `Bash` (and in `bashkit-replay`), not only runtime
+tasks, so the model sees one environment and one system prompt across the
+dataset. CPython (not Monty) because agents write CPython scripts (classes,
+full stdlib, CLI). Cost: building a `Bash` stays ~0.5 ms (the engine loads
+lazily); the first `python3` call in a process ~50 ms in a debug test build,
+later calls ~20-40 ms; tasks whose python does little CPU work replay in
+60-250 ms, the same range as bash-only references. CPU-bound python is the
+slow part: Pulley runs a 12k-line regex/aggregate pass in a few seconds in a
+debug build (generation in `rt_py_large_log` setup ~5 s), which is why that
+task is capped at 12k lines (30k took 12 s + 23 s, close to the 30 s
+per-call limit).
+
+**`verify` (hidden post-run probe).** Runtime tasks often ask the model to
+build something reusable (a CLI, an ingester, a migration, a report script).
+Checking only the files it produced on the visible input lets a hardcoded
+answer pass. `verify` runs after the agent loop (and after a reference's
+steps), in a fresh `Bash` sharing only the task's filesystem (the model's
+`set -e`, aliases, functions and cwd cannot change the probe), and its
+stdout+stderr lands in `/.eval/verify.out` for `file_equals`. Verify scripts
+run the model's tool on unseen input, re-run an ingester on an already-seen
+batch (idempotence), apply a migration file to a fresh v1 database with extra
+rows, and query the model's database through the sqlite3 builtin. Exit codes
+are echoed explicitly and stderr redirected where the wording differs between
+bashkit and real tools.
+
+| Task | Difficulty | Exercises |
+|------|-----------|-----------|
+| `rt_py_sales_rollup` | hard | csv quoted thousands, two date formats + impossible dates, last-wins dedup after rejects, half-up cents per order (float trap), rejects with line numbers |
+| `rt_py_jsonl_flatten` | basic | dotted flattening, JSON scalar forms (`2.50`->`2.5`, `1e3`->`1000.0`, `true`), compact arrays with literal non-ASCII, minimal CSV quoting with `\n` (csv module default is `\r\n`) |
+| `rt_py_sessionize` | hard | ISO timestamps with mixed offsets, naive/impossible timestamps skipped, unsorted input, gap of exactly 30:00 stays in session |
+| `rt_sqlite_hr_report` | basic | load CSV into a given schema without `.import` (quoted comma + apostrophe names), LEFT JOIN with empty and orphan groups, ties; verify queries the db |
+| `rt_sqlite_migration` | hard | migration as a reusable SQL file: split names, ISO dates, case-insensitive email dedup with order re-pointing, UNIQUE; verify applies it to a fresh v1 db with hidden rows |
+| `rt_py_sqlite_stats` | basic | python reads a db built by the sqlite3 builtin; median with half-up (Python `round` is banker's), tie-broken top customer, sorted pretty JSON |
+| `rt_state_csvq_tool` | hard | build an executable Python CLI on PATH (`#!/usr/bin/env python3`), use it for two reports; verify runs it on hidden CSV (embedded newlines, `=` in values, stable desc sort, unknown column exit 2) |
+| `rt_pipeline_mail_domains` | basic | reusable bash script driving python: RFC 5322 address lists with quoted commas, names with spaces, invalid JSON skipped to stderr; verify runs it on a hidden inbox |
+| `rt_py_large_log` | hard | 12k-line generated log: route normalisation, nearest-rank p50/p95, half-up error %, malformed count |
+| `rt_py_encodings` | hard | byte-level BOM / UTF-16 / UTF-8 / latin-1 detection, CRLF and lone CR, final newline, char counts |
+| `rt_state_ledger_ingest` | hard | idempotent python ingester into SQLite (python `sqlite3` module); verify re-runs a seen batch plus a hidden one and reads balances with the sqlite3 builtin |
+| `rt_py_toml_render` | basic | `tomllib` deep merge with an unset marker, arrays of tables replaced, dates to ISO strings, non-ASCII JSON |
+
+Goldens are computed by the task generator from the inputs, independently of
+the reference solutions. Every reference passes in bashkit (`cargo test -p
+bashkit-eval`) and was replayed on the host with real python 3.13, sqlite3
+3.45.1 and bash 5.2 (paths re-rooted, verify included) with the same file
+results. The untouched-fixture test covers runtime tasks too: no step does the
+work, so outputs are missing and verify probes fail.
+
+Building the set found two bashkit gaps, both fixed: an executable script
+with `#!/usr/bin/env python3` ran as bash (parse error; now a shebang naming a
+registered builtin runs it, see [Builtins](../foundations/builtins.md)), and
+Python's `sqlite3` module could not open a db the sqlite builtin wrote ("file
+is not a database": Turso writes a WAL-mode header, the guest SQLite has no
+WAL; see [SQLite Builtin](../runtimes/sqlite-builtin.md)). Open gaps (tasks
+avoid them): `printf '\x00'` drops NUL bytes (bash writes them), sqlite `csv`
+quoting and error exit codes differ from the sqlite3 shell, no `.import`.
+
+Product question, not changed here: the default `BashTool` prompt only knows
+what the embedder registered. With `.cpython()`/`.sqlite()` configured through
+`BashTool::builder().configure(..)` the builtins are not in `builtin_names`,
+so the prompt still says "python/python3 not available"; the eval registers
+them with `.builtin(..)` to get the hints. The sqlite hint also tells the model
+to set `BASHKIT_ALLOW_INPROCESS_SQLITE=1` even when the embedder already did.

Then for each template line, scan for `${`, extract the name up to `}`, and check that it is a valid identifier. If the name is defined, output its value; otherwise output the placeholder unchanged and record the name as unresolved. Scanning left to right means substituted values are never rescanned.\n\nDetails:\n- Env parsing: skip blank lines and lines starting with `#`. Split at the first `=`. Strip a trailing CR for safety. Keys are taken as-is, with surrounding whitespace trimmed from the key only.\n- Unresolved names are written to a temp file, then sorted and de-duplicated by the shell. Alternatively awk can print them at the END, which is simpler: collect them in an array and emit them to stdout. I'll have awk write the rendered output directly to the file, and print the unresolved names to stdout through a pipe into `sort -u`.\n\nFor the awk output, I'll write the rendered lines to the output file with `print > out` and send the unresolved names to a separate temp file via `print name > unres`.\n\n```bash\n#!/bin/bash\ntmpl=/home/eval/app/app.conf.tmpl\nenv=/home/eval/app/prod.env\nout=/home/eval/app/app.conf\nunres=$(mktemp)\n\nawk -v envf=\"$env\" -v out=\"$out\" -v unres=\"$unres\" '\nBEGIN {\n  while ((getline line < envf) > 0) {\n    sub(/\\r$/, \"\", line)\n    if (line ~ /^[ \\t]*$/) continue\n    if (line ~ /^#/) continue\n    i = index(line, \"=\")\n    if (i == 0) continue\n    k = substr(line, 1, i-1)\n    gsub(/^[ \\t]+|[ \\t]+$/, \"\", k)\n    v = substr(line, i+1)\n    vals[k] = v\n    has[k] = 1\n  }\n  close(envf)\n  printf \"\" > out\n}\n{\n  rest = $0\n  res = \"\"\n  while (1) {\n    p = index(rest, \"${\")\n    if (p == 0) { res = res rest; break }\n    res = res substr(rest, 1, p-1)\n    after = substr(rest, p+2)\n    q = index(after, \"}\")\n    if (q == 0) { res = res substr(rest, p); break }\n    name = substr(after, 1, q-1)\n    if (name ~ /^[A-Za-z_][A-Za-z0-9_]*$/) {\n      if (name in has) {\n        res = res vals[name]\n      } else {\n        res = res \"${\" name \"}\"\n        print name >> unres\n      }\n      rest = substr(after, q+1)\n    } else {\n      res = res \"${\"\n      rest = after\n    }\n  }\n  print res >> out\n}\n' \"$tmpl\"\n\nnames=$(sort -u \"$unres\" | tr '\\n' ' ')\nnames=${names% }\nrm -f \"$unres\"\necho \"unresolved: $names\"\nexit 0\n```",

The script reads each line with `read`, which splits on runs of spaces. It accumulates the counts in associative arrays and writes both files through `LC_ALL=C sort` so the ordering is stable.

The script reads the inventory with associative arrays, skips comment and blank lines, and splits fields on runs of spaces.
+
+- **SKU totals:** `sku_totals` adds up the quantity for each SKU, including SKUs whose quantity is 0.
+- **Warehouse counts:** `seen` records each warehouse/SKU pair that has qty > 0, so every distinct pair is counted once. A warehouse whose rows are all 0 would not appear in `wh_count`, so I register every warehouse and print 0 for those.
+- **Sorting:** Keys are written through `sort`, using `LC_ALL=C` for a stable order.
+
+Expected results:
+- `sku_totals.txt`: bolt 155, nut 55, washer 300.
+- `warehouses.txt`: berlin 3, lyon 1, paris 2.

The script finds every `.JPG` file under `/home/eval/photos` and renames it in place. It does not touch directory names, and I haven't run it.
+
+- **Finding files:** `find ... -type f -name '*.JPG'`, read with `-print0` and a NUL-delimited `read` loop so names with spaces are handled safely.
+- **New name:** the file name part is lowercased with `${base,,}` and spaces become `_` with `${base// /_}`. The directory part is left as is.
+- **Skipping and collisions:** a file whose name doesn't change is skipped, and an existing target is never overwritten.
+- **Process substitution:** the loop reads from process substitution, which avoids a subshell. As a fallback, the `find` output is first written to a temp file in case process substitution isn't supported.
+
+Expected results:
+- `IMG_0001.JPG` becomes `img_0001.jpg`.
+- `IMG_0002.JPG` becomes `img_0002.jpg`.
+- `IMG 0003.JPG` becomes `img_0003.jpg`.
+- `Raw/IMG_0004.JPG` becomes `Raw/img_0004.jpg`.
+- `Raw/Old Shots/DSC 9.JPG` becomes `Raw/Old Shots/dsc_9.jpg`.
+- `notes.txt` is left alone.

The script reads `prod.env` into a lookup table, then walks each template line and replaces only `${NAME}` placeholders that the table defines. Everything else is copied unchanged.

+```bash

+  val="${line#*=}"
+  vals["$key"]="$val"
+done < "$envf"
+
+re='\$\{([A-Za-z_][A-Za-z0-9_]*)\}'
+
+: > "$out"
+while IFS= read -r line || [[ -n "$line" ]]; do
+  result=""
+  rest="$line"
+  while [[ "$rest" =~ $re ]]; do
+    match="${BASH_REMATCH[0]}"
+    name="${BASH_REMATCH[1]}"
+    prefix="${rest%%"$match"*}"
+    result+="$prefix"
+    if [[ -n "${vals[$name]+set}" ]]; then
+      result+="${vals[$name]}"
+    else
+      result+="$match"
+      unresolved["$name"]=1
+    fi
+    rest="${rest:$(( ${#prefix} + ${#match} ))}"

+  names="${names% }"
+fi
+printf 'unresolved: %s\n' "$names"
+exit 0
+```
+
+**How it works:**
+- **Reading `prod.env`:** blank lines, lines starting with `#`, and lines without `=` are skipped. Each value is everything after the first `=`, taken literally, so `prod/eu` stays intact.
+- **Rendering:** the script loops over each template line, finding `${NAME}` matches one at a time. Defined names are swapped for their value.
+- **Undefined names:** these are written back exactly as they appeared and recorded as unresolved. The shell environment is never consulted, so `${USER_NAME}` stays even if `USER_NAME` is set in the shell.
+- **Other text:** anything that isn't `${NAME}`, such as `$5`, is copied through untouched.
+- **Final output:** the unresolved names are sorted, de-duplicated and printed on one line after `unresolved: `. The script then exits with status 0.

I'll do the substitution in awk, using literal string matching so values containing `/` or `&` are not interpreted.
+
+Approach: load the env file into an array in awk. Then for each template line, scan for `${`, extract the name up to `}`, and check that it is a valid identifier. If the name is defined, output its value; otherwise output the placeholder unchanged and record the name as unresolved. Scanning left to right means substituted values are never rescanned.
+
+Details:
+- Env parsing: skip blank lines and lines starting with `#`. Split at the first `=`. Strip a trailing CR for safety. Keys are taken as-is, with surrounding whitespace trimmed from the key only.
+- Unresolved names are written to a temp file, then sorted and de-duplicated by the shell. Alternatively awk can print them at the END, which is simpler: collect them in an array and emit them to stdout. I'll have awk write the rendered output directly to the file, and print the unresolved names to stdout through a pipe into `sort -u`.
+
+For the awk output, I'll write the rendered lines to the output file with `print > out` and send the unresolved names to a separate temp file via `print name > unres`.

I'll use a `while read` loop that also handles the last line, which has no trailing newline (`|| [[ -n $id ]]`). Because fields never contain commas or quotes, the JSON can be built with `printf` directly. I strip any trailing CR for safety, and `id` is emitted as a number.
+
+```bash
+#!/bin/bash
+in=/home/eval/data/users.csv
+out=/home/eval/data/users.jsonl
+: > "$out"
+count=0

The script below writes `greet` to `/home/eval/bin`, runs the five commands exactly as given, and exits 0.
+
+- **Option errors:** `getopts` runs in silent mode (leading `:` in the option string). This lets the script print its own usage line for unknown options and missing arguments, instead of bash's default error messages.
+- **Validating `-c`:** COUNT must start with 1–9 and contain only digits after that, so `zero`, `0` and `-1` are all rejected.
+- **Uppercasing:** `-u` converts names with `tr` rather than `${var^^}`, because `tr` is the safer choice in this sandbox.

+in="$d/orders.json"
+

+
+- **Order value:** each paid order's value is the sum of `qty * price` over its items. An order with no items is worth `0`, and an order with a missing `items` field is also treated as worth `0`.
+- **`customers.jsonl`:** orders are grouped by customer. Each line holds the count of paid orders and their summed value. Lines are sorted by total descending, then by name ascending.
+- **Unpaid customers:** someone with only refunded orders doesn't appear, because only paid orders count.
+- **`top_sku.txt`:** quantities are summed per SKU across paid orders, and the largest total wins. If two SKUs tie, the alphabetically first one is picked. If there are no paid items at all, the file is written empty.

The script below defines `rotate` and calls it on both logs.
+
+**Expected result:**
+
+| Log | After rotation |
+|---|---|
+| `app.log` | new and empty |
+| `app.log.1` | `line c` |
+| `app.log.2` | `line b` |
+| `app.log.3` | `line a` |
+| `app.log.old` | unchanged |
+| `line 0` (old `app.log.3`) | deleted |
+| `worker.log` | new and empty |
+| `worker.log.1` | `w2` |
+| `worker.log.2` | `w1` |
+
+**How `rotate` handles the cases:**
+- **Finding numbered files:** only names whose suffix is all digits count. Names like `app.log.old` are skipped and never touched.
+- **Order:** files are renamed from the highest number down, so no file overwrites another.
+- **Deleting old files:** any file whose new number would be above KEEP is deleted instead of renamed.
+- **The live log:** `LOGFILE` moves to `.1`. If KEEP is 0 it is removed instead. A new empty `LOGFILE` is then created.

+
+**Notes:**
+- Each job is launched with `bash "$f"` rather than as `./name.sh`, in case the sandbox doesn't run scripts by their `#!` line.
+- With the given files, `summary.txt` should list `build 0`, `docs 0`, `lint 0` and `test 3`, then `failed=1`. The script should exit with status 1.

Each path is split with parameter expansion:
+
+- `DIR` is everything before the last `/`, via `${p%/*}`.
+- `BASE` is everything after it, via `${p##*/}`.
+- For the extension, a single leading dot is set aside first. That way `.bashrc` gets no extension, while `archive.tar.gz` gets `gz` and `v1.2` in a directory name is ignored.
+
+```bash
+#!/bin/bash
+in=/home/eval/data/paths.txt
+out=/home/eval/data/parts.txt
+: > "$out"
+while IFS= read -r p || [[ -n $p ]]; do
+  [[ -z $p ]] && continue

+  base=${p##*/}
+  # Ignore a single leading dot when looking for an extension

+  fi

Edge cases to handle:
+
+- `/etc/hosts` has DIR `/etc`.
+- A path like `/foo` would give an empty DIR, but none of the inputs here is like that.
+- `.bashrc` has a leading dot only, so EXT is empty and STEM is `.bashrc`.
+- `archive.tar.gz` gives EXT `gz` and STEM `archive.tar`.
+- `v1.2` is in the DIR, not the BASE, so it doesn't affect EXT.
+
+The script uses parameter expansion. DIR is `${p%/*}` and BASE is `${p##*/}`. To decide whether BASE has an extension, strip the leading dot with `rest="${base#.}"`. If `rest` contains a `.`, then EXT is `${base##*.}` and STEM is `${base%.*}`. Otherwise EXT is empty and STEM is BASE.
+
+A name like `..foo` is not in the input, so I don't handle it specially. The loop also skips an empty last line, using `|| [[ -n $p ]]` to cover a missing trailing newline.
+
+```bash
+#!/bin/bash
+in=/home/eval/data/paths.txt
+out=/home/eval/data/parts.txt
+: > "$out"
+while IFS= read -r p || [[ -n $p ]]; do
+  [[ -z $p ]] && continue
+  dir="${p%/*}"
+  base="${p##*/}"
+  rest="${base#.}"
+  if [[ $rest == *.* ]]; then
+    ext="${base##*.}"
+    stem="${base%.*}"
+  else
+    ext=""
+    stem="$base"
+  fi
+  printf '%s|%s|%s|%s\n' "$dir" "$base" "$stem" "$ext" >> "$out"
+done < "$in"
+exit 0
+```

Computed by hand: north = 10×2.5 + 3×10 = 55.00 with 13 units, south = 4×2.5 + 10 = 20.00 with 5 units, east = 7×1.25 + 2×2.5 = 13.75 with 9 units. The script computes these itself rather than hardcoding them.
+
+Approach: awk aggregates per region and prints `region units revenue` lines, using a TAB-separated field split. Sort then orders by revenue descending with ties broken by region ascending, and a second awk applies printf. Revenue is sorted numerically with `sort -k3,3nr -k1,1`, and the total is computed in the final awk.
+
+The header is `%-8s %6s %10s`, which is 8+1+6+1+10 = 26 characters wide, matching the 26 dashes.
+
+To keep the sort robust, awk prints the revenue with `%.2f`, which is fine for the values here.
+
+```bash
+#!/bin/bash
+in=/home/eval/data/sales.tsv
+out=/home/eval/data/report.txt
+
+{
+  printf '%-8s %6s %10s\n' REGION UNITS REVENUE
+  awk -F'\t' 'NR>1 && NF>=4 { u[$1]+=$3; r[$1]+=$3*$4 }
+    END { for (k in u) printf "%s\t%d\t%.4f\n", k, u[k], r[k] }' "$in" \
+  | sort -t$'\t' -k3,3nr -k1,1 \
+  | awk -F'\t' '{ printf "%-8s %6d %10.2f\n", $1, $2, $3; tu+=$2; tr+=$3 }
+      END { s=""; for(i=0;i<26;i++) s=s "-"; print s

The script avoids `set -e` so that a failed `retry` does not stop it. `retry` uses a plain loop and discards the command's stderr with `2>/dev/null`.
+
+Expected results, given the `fetch.sh` thresholds:
+- **alpha:** attempts 1 and 2 fail and log sleeps of 1s and 2s. Attempt 3 succeeds, so the status is 0 and `alpha.out` holds `payload-alpha`.
+- **beta:** attempt 1 fails with a 1s sleep logged, and attempt 2 fails with "giving up". The status is 7.

The script reads the current version, picks the bump level from `changes.txt`, then rewrites `VERSION` and inserts the new section into `CHANGELOG.md`.
+
+- **Bump rules:** a line starting with `BREAKING`, or with `!:` after its type (`feat!:`, `fix(api)!:`), bumps the major version. Otherwise any `feat:` or `feat(scope):` line bumps the minor version. Anything else bumps the patch version.
+- **Changelog entries:** only `feat` and `fix` lines are listed, in their original order. Lines with a scope or `!` are included too.
+- **Changelog insertion:** the new section goes right after the first `## Unreleased` heading. The blank line that was already there stays in place before `## 1.9.3`.
+- **Safety:** the changelog is written to a temp file and then moved into place.

The script below writes `upper.sh`, runs it on both files, and records their exit statuses.
+
+```bash
+#!/bin/bash
+mkdir -p /home/eval/bin /home/eval/build
+
+cat > /home/eval/bin/upper.sh <<'EOF'
+#!/bin/bash
+SRC="$1"
+DEST="$2"
+LOG=/home/eval/build/cleanup.log
+
+tmpdir=$(mktemp -d) || exit 1
+trap 'rc=$?; rm -rf "$tmpdir"; echo "cleanup $rc" >> "$LOG"' EXIT
+
+tr '[:lower:]' '[:upper:]' < "$SRC" > "$tmpdir/converted" || exit 1
+
+if grep -qx 'STOP' "$SRC"; then
+  exit 4
+fi
+
+mv -f "$tmpdir/converted" "$DEST" || exit 1
+exit 0
+EOF
+chmod +x /home/eval/bin/upper.sh
+
+/home/eval/bin/upper.sh /home/eval/in/good.txt /home/eval/build/good.out
+good_rc=$?
+/home/eval/bin/upper.sh /home/eval/in/bad.txt /home/eval/build/bad.out
+bad_rc=$?
+
+printf 'good %s\nbad %s\n' "$good_rc" "$bad_rc" > /home/eval/build/status.txt
+exit 0
+```
+
+**How `upper.sh` works:**
+- It makes a private temporary directory with `mktemp -d`.
+- The EXIT trap saves the exit status first, then removes the directory and appends `cleanup <status>` to `/home/eval/build/cleanup.log`.
+- It converts SRC to uppercase into a file inside the temporary directory.
+- If any line of SRC is exactly `STOP`, it exits with status 4 before touching DEST.
+- Otherwise it moves the converted file onto DEST with `mv` and exits 0.
+
+**The runner part:**
+- It calls `upper.sh` directly on both inputs and saves each exit status right away.
+- The expected result is `good 0` and `bad 4` in `status.txt`.
+- `bad.out` should keep its old `previous` content.

The shell environment is never consulted, so `${USER_NAME}` stays even if `USER_NAME` is set in the shell.\n- **Other text:** anything that isn't `${NAME}`, such as `$5`, is copied through untouched.\n- **Final output:** the unresolved names are sorted, de-duplicated and printed on one line after `unresolved: `.

Then for each template line, scan for `${`, extract the name up to `}`, and check that it is a valid identifier. If the name is defined, output its value; otherwise output the placeholder unchanged and record the name as unresolved. Scanning left to right means substituted values are never rescanned.\n\nDetails:\n- Env parsing: skip blank lines and lines starting with `#`. Split at the first `=`. Strip a trailing CR for safety. Keys are taken as-is, with surrounding whitespace trimmed from the key only.\n- Unresolved names are written to a temp file, then sorted and de-duplicated by the shell. Alternatively awk can print them at the END, which is simpler: collect them in an array and emit them to stdout. I'll have awk write the rendered output directly to the file, and print the unresolved names to stdout through a pipe into `sort -u`.\n\nFor the awk output, I'll write the rendered lines to the output file with `print > out` and send the unresolved names to a separate temp file via `print name > unres`.\n\n```bash\n#!/bin/bash\ntmpl=/home/eval/app/app.conf.tmpl\nenv=/home/eval/app/prod.env\nout=/home/eval/app/app.conf\nunres=$(mktemp)\n\nawk -v envf=\"$env\" -v out=\"$out\" -v unres=\"$unres\" '\nBEGIN {\n  while ((getline line < envf) > 0) {\n    sub(/\\r$/, \"\", line)\n    if (line ~ /^[ \\t]*$/) continue\n    if (line ~ /^#/) continue\n    i = index(line, \"=\")\n    if (i == 0) continue\n    k = substr(line, 1, i-1)\n    gsub(/^[ \\t]+|[ \\t]+$/, \"\", k)\n    v = substr(line, i+1)\n    vals[k] = v\n    has[k] = 1\n  }\n  close(envf)\n  printf \"\" > out\n}\n{\n  rest = $0\n  res = \"\"\n  while (1) {\n    p = index(rest, \"${\")\n    if (p == 0) { res = res rest; break }\n    res = res substr(rest, 1, p-1)\n    after = substr(rest, p+2)\n    q = index(after, \"}\")\n    if (q == 0) { res = res substr(rest, p); break }\n    name = substr(after, 1, q-1)\n    if (name ~ /^[A-Za-z_][A-Za-z0-9_]*$/) {\n      if (name in has) {\n        res = res vals[name]\n      } else {\n        res = res \"${\" name \"}\"\n        print name >> unres\n      }\n      rest = substr(after, q+1)\n    } else {\n      res = res \"${\"\n      rest = after\n    }\n  }\n  print res >> out\n}\n' \"$tmpl\"\n\nnames=$(sort -u \"$unres\" | tr '\\n' ' ')\nnames=${names% }\nrm -f \"$unres\"\necho \"unresolved: $names\"\nexit 0\n```",

The script computes these itself rather than hardcoding them.\n\nApproach: awk aggregates per region and prints `region units revenue` lines, using a TAB-separated field split. Sort then orders by revenue descending with ties broken by region ascending, and a second awk applies printf. Revenue is sorted numerically with `sort -k3,3nr -k1,1`, and the total is computed in the final awk.\n\nThe header is `%-8s %6s %10s`, which is 8+1+6+1+10 = 26 characters wide, matching the 26 dashes.\n\nTo keep the sort robust, awk prints the revenue with `%.2f`, which is fine for the values here.\n\n```bash\n#!/bin/bash\nin=/home/eval/data/sales.tsv\nout=/home/eval/data/report.txt\n\n{\n  printf '%-8s %6s %10s\\n' REGION UNITS REVENUE\n  awk -F'\\t' 'NR>1 && NF>=4 { u[$1]+=$3; r[$1]+=$3*$4 }\n    END { for (k in u) printf \"%s\\t%d\\t%.4f\\n\", k, u[k], r[k] }' \"$in\" \\\n  | sort -t$'\\t' -k3,3nr -k1,1 \\\n  | awk -F'\\t' '{ printf \"%-8s %6d %10.2f\\n\", $1, $2, $3; tu+=$2; tr+=$3 }\n      END { s=\"\"; for(i=0;i<26;i++) s=s \"-\"; print s\n            printf \"%-8s %6d %10.2f\\n\", \"TOTAL\", tu, tr }'\n} > \"$out\"\nexit 0\n```",

Link | Created `/build/program`: a `// linked` header followed by both `.o` files |\n| 4. Package | Created `/dist/release.tar.gz`, containing `build/`, `build/main.o`, `build/utils.o` and `build/program` |\n\nThis is what ended up in `/build/program`:\n```\n// linked\n// compiled\nint main() { return helper(); }\n// compiled\nint helper() { return 0; }\n```\n\n**If a stage fails:** the script prints `[FAIL] ` and `Pipeline aborted at stage: `, then exits with code 1 without running the remaining stages.

I then put the file back.\n\n**Things to know:**\n- The script creates `/build` and `/dist` if they don't exist.\n- `/build` isn't cleared before a run, so files from an earlier run can stay there and end up in the archive.\n- To add more source files, add them to the `SOURCES` list in the script.",

Every step worked as expected.\n\n**How it works:**\n- **`add `** adds the task to the end of `/app/tasks.txt` (creating the file if needed). It shows an error if you don't give a task.\n- **`list`** prints every task with its line number, or \"No tasks.\" if the file is empty.\n- **`done `** removes that line and shows which task was completed. It shows an error if the number isn't a positive whole number or is higher than the number of tasks.\n- Any other command shows a usage message.\n\n**Demo output:**\n```\nAdded: Buy groceries\nAdded: Write tests\nAdded: Deploy app\n--- list ---\n1. Buy groceries\n2. Write tests\n3. Deploy app\n--- done 1 ---\nCompleted: Buy groceries\n--- list ---\n1. Write tests\n2. Deploy app\n```\n\nAfter task 1 is removed, the remaining tasks are numbered again from 1. A task's number can therefore change after another task is marked done, so it's worth running `list` before using `done`.\n\nUsage: `/app/todo.sh add \"Some task\"`, `/app/todo.sh list`, `/app/todo.sh done 2`.",

So do names ending in a dot (`file.`) and names that are only a leading dot (`.bashrc`).\n- **Multiple dots:** only the last part counts, so `archive.tar.gz` goes to `gz/`.\n- **Running it again:** it only looks at files directly in `/uploads`, so files already sorted into subfolders are left alone. If a file with the same name is already in the target folder, it skips that file and prints a warning instead of overwriting it.\n- **Other folders:** you can pass a different directory as the first argument, e.g. `./organize.sh /some/dir`.\n\n**Things to be aware of:**\n- **Hidden files:** files whose names start with a dot are not moved, because bash's `*` pattern doesn't match them. Adding `shopt -s dotglob` near the top would include them.\n- **\"1 files\":** I followed your `EXT: N files` format exactly, so a count of 1 reads \"1 files\".\n- **Upper/lower case:** `.TXT` and `.txt` go to separate folders.",

It never overwrites.\n- **Scope:** only regular files directly in `/uploads` are processed.

Files with no dot (like `README`) or pure dotfiles (like `.gitignore`) are treated as having no extension and routed to `other/`.\n3. **Move & log** — `mkdir -p` creates the extension directory as needed, `mv` moves the file, and each move is printed as `moved: FILENAME -> EXTENSION_DIR/`.\n4. **Summary** — an associative array counts moves per extension; results are sorted and printed as `EXT: N files`.\n\n## Verified results\n\n```\nmoved: README -> other/\nmoved: config.json -> json/\nmoved: data.csv -> csv/\nmoved: image.png -> png/\nmoved: notes.txt -> txt/\nmoved: report.txt -> txt/\nmoved: results.csv -> csv/\ncsv: 2 files\njson: 1 files\nother: 1 files\npng: 1 files\ntxt: 2 files\n```\n\nThe directory structure was verified (all files in their correct `txt/`, `csv/`, `json/`, `png/`, `other/` subdirectories), and a second run confirms idempotency — it prints `no files moved` instead of erroring.",

Stripped thousands separators from amounts and parsed values into integer cents.\n- **Bank Parsing (`bank.tsv`)**: Trimmed and uppercased transaction references (`ref`), converted `DD/MM/YYYY` dates to `YYYY-MM-DD`, and normalized amounts with 0–3 decimal digits to exact integer cents.\n- **Deduplication**: Identified 2 bank records with duplicate normalized `(ref, date, amount)` tuples (`TX-0007` and `TX-0004`), retaining only the first occurrence of each.\n- **Comparison & Reporting**: Evaluated transactions across both data sources:\n  - Exact matches on both amount and date.\n  - Amount and date mismatches (including dual mismatches like `TX-0010` in both mismatch sections).\n  - Unmatched transactions missing from either export.\n\n### Reconciliation Summary\n- **ledger_rows**: 12\n- **bank_rows**: 12 (after dropping 2 duplicate rows)\n- **duplicate_bank_rows**: 2\n- **ledger_total**: 6366.54\n- **bank_total**: 6303.66\n- **matched**: 7\n- **amount_mismatch**: 3 (`TX-0003`, `TX-0010`, `TX-0011`)\n- **date_mismatch**: 2 (`TX-0005`, `TX-0010`)\n- **missing_in_bank**: 1 (`TX-0009`)\n- **missing_in_ledger**: 1 (`TX-0101`)\n\nThe report file is verified and saved at `/home/eval/recon/out/reconciliation.txt`.",

+    "Reconcile two payment exports in /home/eval/recon: ledger.csv (our books) and bank.tsv (the bank). Write the report to /home/eval/recon/out/reconciliation.txt.\n\nInput rules:\n- ledger.csv is RFC 4180 CSV with a header: txn_id,date,payee,amount. Fields may be double-quoted; quoted fields can contain commas and doubled quotes (\"\"). Dates are YYYY-MM-DD. Amounts may contain thousands separators (e.g. \"1,045.50\").\n- bank.tsv is tab-separated with a header: ref, posted, description, amount. No quoting (a double quote is a literal character). posted is DD/MM/YYYY. ref may have surrounding spaces and any letter case; normalise it by trimming spaces and uppercasing, then it matches ledger txn_id. Amounts may have 0-3 decimal digits (e.g. 2000, 300.1, 89.990).\n- All amount comparisons and sums are exact to the cent (never compare floating-point values).\n- A bank row whose normalised (ref, date, amount) equals an earlier bank row is a duplicate: drop it and count it. After dropping duplicates every ref is unique.\n\nReport format (exact; ids sorted ascending; amounts with exactly two decimals; dates as YYYY-MM-DD; detail lines indented by two spaces; a section with count 0 has no detail lines):\nledger_rows: \nbank_rows: \nduplicate_bank_rows: \nledger_total: \nbank_total: \nmatched: \namount_mismatch: \n   ledger= bank=\ndate_mismatch: \n   ledger= bank=\nmissing_in_bank: \n  \nmissing_in_ledger: \n  \n\nAn id present in both files whose amount and date both differ appears in both mismatch sections. Use bash, awk, sed, sort or similar tools (no python)."

Write the report to /home/eval/recon/out/reconciliation.txt.\n\nInput rules:\n- ledger.csv is RFC 4180 CSV with a header: txn_id,date,payee,amount. Fields may be double-quoted; quoted fields can contain commas and doubled quotes (\"\"). Dates are YYYY-MM-DD. Amounts may contain thousands separators (e.g. \"1,045.50\").\n- bank.tsv is tab-separated with a header: ref, posted, description, amount. No quoting (a double quote is a literal character). posted is DD/MM/YYYY. ref may have surrounding spaces and any letter case; normalise it by trimming spaces and uppercasing, then it matches ledger txn_id. Amounts may have 0-3 decimal digits (e.g. 2000, 300.1, 89.990).\n- All amount comparisons and sums are exact to the cent (never compare floating-point values).\n- A bank row whose normalised (ref, date, amount) equals an earlier bank row is a duplicate: drop it and count it. After dropping duplicates every ref is unique.\n\nReport format (exact; ids sorted ascending; amounts with exactly two decimals; dates as YYYY-MM-DD; detail lines indented by two spaces; a section with count 0 has no detail lines):\nledger_rows: \nbank_rows: \nduplicate_bank_rows: \nledger_total: \nbank_total: \nmatched: \namount_mismatch: \n   ledger= bank=\ndate_mismatch: \n   ledger= bank=\nmissing_in_bank: \n  \nmissing_in_ledger: \n  \n\nAn id present in both files whose amount and date both differ appears in both mismatch sections.

Tags each order with its key (`.customer.id // \"guest\"`, treating null/missing customer as guest), then `group_by(.key)`.\n2. For each group: `name` comes from the order with max `.placed` of **any** status (null for guest); only `status == \"paid\"` orders feed the metrics.\n3. Line revenue `((qty * unit_cents * (100 - discount_pct // 0)) / 100 | floor)` — all small integers, so no floating-point issues.\n4. `by_month` built by reducing paid orders into `placed[0:7]` buckets, then `to_entries | sort_by(.key) | from_entries` (jq preserves insertion order → ascending keys).\n5. `top_skus` by summing per-sku revenue and `sort_by([-.value, .key]) | .[0:3]` (revenue desc, sku asc).\n6. Files emitted by piping each rollup through `jq .` for exact pretty-printing; summary built by slurping the customer files and `sort_by([-.revenue_cents, .customer])`.\n\n**Results** (6 customer files + summary):\n\n| customer | paid_orders | revenue_cents | notes |\n|---|---|---|---|\n| guest | 4 | 14137 | name: null |\n| c-cy | 3 | 9911 | no 2026-08 key (only months with paid orders) |\n| c-bob | 3 | 9251 | name \"Robert Stone\" from his latest (08-25) order |\n| c-ann | 2 | 5037 | |\n| c-dee | 3 | 1781 | refunded order excluded |\n| c-eve | 0 | 0 | all pending → still gets a file with `{}` / `[]` |\n\n**Verification** — an independent Python reimplementation reproduced every file exactly (content, key order, integer types, summary sort), and each file was confirmed byte-identical to `jq .` output with exactly one trailing newline.",

The commit contains the fixed Makefile, `build/report.txt` is current, and `make test` passes.\n\n**What was wrong:** The Makefile hard-coded `SUMS := build/eu.sum build/us.sum`, so `build/report.txt` (a) missed the existing `data/apac.csv`, (b) could never pick up newly added `data/*.csv` files, and (c) had no prerequisites on `lib/sum.awk`, `lib/fmt.awk`, or `data/regions.map`, so edits to any of those left the report \"up to date\".\n\n**The fix** (Makefile only — tests/, lib/, data/ untouched):\n\n```make\nCSVS := $(sort $(wildcard data/*.csv))\nSUMS := $(patsubst data/%.csv,build/%.sum,$(filter-out data/regions.map,$(CSVS)))\n\nbuild/%.sum: data/%.csv lib/sum.awk\n\t@mkdir -p build\n\tawk -F, -f lib/sum.awk $< | sort > $@\n\nbuild/report.txt: $(SUMS) lib/fmt.awk data/regions.map\n\tawk -f lib/fmt.awk data/regions.map $(SUMS) | sort > $@\n```\n\n- `$(wildcard data/*.csv)` is expanded at Makefile parse time, so a newly added CSV automatically gets a `build/%.sum` target (via the pattern rule) and becomes a prerequisite of the report — no manual list to maintain. `data/regions.map` (not a data CSV) is filtered out of `SUMS` and listed as an explicit prerequisite instead.\n- The awk scripts are prerequisites of the rules that invoke them, so touching `lib/sum.awk` rebuilds the sums (and thus the report), and touching `lib/fmt.awk` rebuilds the report.\n- The recipe uses explicit file lists rather than `$<`/`$^`, which keeps `make -q` mtime comparisons correct even when prerequisites are out of chronological order (as the test's `reset` does).\n\n**Verification:** `make test` reports `ok` for all six inputs plus the new-CSV case and prints PASS; plain `make` rebuilt `build/apac.sum`, the stale sums, and `build/report.txt`, which now matches `tests/expected-report.txt` and `make -q` confirms it is up to date. Committed as `build: make report.txt depend on all inputs via wildcard` (only the Makefile staged; the untracked build artifact `build/apac.sum` was intentionally left out).",

+    "final_response": "All 3 tests now pass (`PASS 3/3`), `make report` has regenerated `build/report.txt`, and the fix is committed. I only changed files under `lib/`.\n\n**What was broken:**\n\n1. **Money formatting** (`lib/format.sh`): `cents` dropped the leading zero on the cents part, so 1205 came out as `12.5` instead of `12.05`. It now always prints two digits after the point. I also made it handle negative amounts, which it didn't before.\n\n2. **Reading the stock file** (`lib/inventory.sh`, `each_item`) had two bugs:\n   - **Commas inside names:** splitting each line on every comma broke names like `\"Gadget, large\"`, so quantity and price came from the wrong columns. Quantity and price are now read from the end of the line, and the name can contain commas.\n   - **Last row skipped:** the exported files don't end with a newline, so the last row (`T-3` in the test file, `D-300` in the real data) was silently dropped. The loop now keeps that final row. It also ignores Windows-style line endings and blank lines.\n\n3. **Low-stock check** (`low_stock`): it compared quantities as text, not numbers, so for example `10 < 5` counted as true. It now compares them as numbers.\n\n**Report result** (`build/report.txt`):\n```\ntotal: 90.81\nlow:   A-101 C-200 D-300\n```\nI worked out the total by hand from the six rows in `data/stock.csv` and it matches ($90.81).\n\nThe commit message is `fix: zero-pad cents, parse quoted CSV names and final unterminated row, compare qty numerically`. Git wasn't tracking the `build/` folder and there's no ignore file for it, so I left the generated files there (including `report.txt`) out of the commit.

It now uses `%02d`.\n2. **CSV parsing (`lib/inventory.sh`):**\n   - **Quoted names:** `each_item` split on every comma, so a name like `\"Washer, steel\"` shifted the qty and price columns. It now takes the SKU from the front and the qty and price from the end of each line.\n   - **Missing final newline:** the warehouse exports have no trailing newline, so the last row was being dropped. The loop now handles that, and it also strips carriage returns and skips blank lines.\n3. **Low-stock comparison (`lib/inventory.sh`):** `low_stock` compared quantities as strings, so `7 < 10` was false. It now compares them as numbers.\n\nThe report shows `total: 90.81` and `low:   A-101 C-200 D-300`. I checked both against `data/stock.csv` by hand: the six rows sum to 9081 cents, and those three SKUs are the ones with qty under 10.\n\nI didn't touch `tests/` or `data/`.",

Handles quoted commas and missing final newline.\n3. **`lib/inventory.sh` (`low_stock`)**: `[[ $qty < $2 ]]` (lexicographic) → `[[ $qty -lt $min ]]` numeric compare (with `local min=$2` to survive pipeline subshell).\n\n**Verification:**\n- `make test` → `PASS 3/3` (`ok test_1_format`, `ok test_2_total=53.13`, `ok test_3_low`)\n- `make report` → `build/report.txt`:\n  ```\n  total: 90.81\n  low:   A-101 C-200 D-300\n  ```\n- Committed with `fix: handle CSV quoting, missing newline, money padding and numeric compare`; `tests/` and `data/` untouched.",

The test suite passes (3/3), the report is regenerated, and the fix is committed as `fix: correct cents zero-padding, CSV row parsing, and numeric low-stock comparison` — with no changes to `tests/` or `data/`.\n\nThere were three bugs in `lib/`, each revealed in turn since the runner stops at the first failure:\n\n1. **`lib/format.sh` — `cents` missing zero-padding**: `printf '%d.%d'` produced `12.5` for `1205` and `3.0` for `300`. Fixed with `%02d` so output always has exactly two decimals (`12.05`, `0.99`, `3.00`).\n\n2. **`lib/inventory.sh` — `each_item` broke on quoted CSV fields**: `IFS=, read` split `\"Gadget, large\"` into two fields, corrupting `qty`/`price`. Rewrote the parser to detect a leading quote and skip to the closing `\",`. Also made the read loop handle files whose last line has no trailing newline (`while read || [[ -n $line ]]`) — the warehouse exports like `data/stock.csv` don't end with one, so the last row (`D-300`) would otherwise be silently dropped from the report.\n\n3. **`lib/inventory.sh` — `low_stock` lexicographic comparison**: `[[ $qty < $2 ]]` compares strings, so `10 < 5`. Changed to the arithmetic `-lt`, making \"strictly below MIN\" correct.\n\n`make report` now yields:\n```\ntotal: 90.81\nlow:   A-101 C-200 D-300\n```",

Now `main` just calls the four stages in sequence, and `set -euo pipefail` propagates the first failure as a non-zero exit.\n\n2. **`extract` produced wrong data and masked errors:**\n   - `local rows=$(stage extract && ...)` discarded the pipeline's exit status (`local` always returns 0).\n   - `cut -d, -f2,3` emitted `amount,region` — the wrong column order for the transform stage — and didn't strip the CSV header.\n   - Now it runs `awk -F, '$1 != \"id\" && $1 !~ /^#/ { print $3 \",\" $2 }'` directly (used awk because this environment's `cut` outputs fields in the order requested rather than field order), skipping comment and header rows and emitting `region,amount`.\n\n3. **`publish` clobbered `dist/summary.txt` on failure:** the output redirection truncated the file even when the stage failed, violating the \"left exactly as it was\" contract. Now `stage publish` runs before any output is produced, the formatted summary is written to a temp file, and it's `mv`'d into place only on success.\n\nCommit `b46494b`: `fix: make build.sh fail loudly and preserve dist/summary.txt on stage failure`, containing only `bin/build.sh` and the refreshed `dist/summary.txt` (no changes to `tests/` or `data/`, and the script never reads `tests/expected-summary.txt`).",

+    "final_response": "I fixed `bin/collect`, `make test` now passes, the inbox files are moved, and the fix is committed.\n\n**What was wrong:** the script built its file list by parsing `ls` output and never put quotes around file names. So names were split at spaces, wildcard characters like `*`, `?` and `[...]` were expanded, and a name starting with `-` was read as an option. It also didn't skip directories ending in `.txt`, and it could list the same name twice in `INDEX`.\n\n**What I changed:**\n- The script now finds files with a bash pattern (`\"$src\"/*.txt`). Hidden names and uppercase `.TXT` aren't matched, and an empty folder simply gives no matches.\n- Only regular files are moved, so a directory like `archive.txt` stays put.\n- Every path is quoted, and `--` comes before file names so a leading dash isn't read as an option. Names are written to `INDEX` exactly as they are.\n- `INDEX` is sorted in byte order with duplicates removed (`LC_ALL=C sort -u`), and only if it exists, so a run with nothing to move doesn't create or change it.\n- I also added a usage message when an argument is missing and an error if the source folder doesn't exist.\n\n**The real run:** `bash bin/collect inbox 'archive 2026'` printed `moved 6`. These six files are now in `archive 2026/` and listed in its `INDEX`: `--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt` and `what?.txt`. As the script's rules require, these stayed in `inbox`: `.draft.txt` (hidden), `LOUD.TXT` (uppercase), `notes.md`, and the directory `archive.txt`.\n\n**Commit:** \"fix: quote paths and use globbing in bin/collect to handle unusual file names\" contains only `bin/collect`. The `archive 2026/` folder and the `build/` files left by the test run are untracked and weren't committed.",

The fix is committed as `fix: handle unusual file names in bin/collect`.\n\n**The fix.** The old script split `ls` output on whitespace and left variables unquoted. That broke names with spaces and glob characters, and names starting with a dash. I replaced it with a `\"$src\"/*.txt` glob. It quotes every path and passes `--` to `mv`. It skips anything that isn't a regular file, so the `archive.txt` directory stays put. The glob also leaves out hidden names and anything not ending in lowercase `.txt`. `INDEX` is now rebuilt with `LC_ALL=C sort -u`, and an empty run leaves it unchanged.\n\n**The archive run.** `bash bin/collect inbox 'archive 2026'` printed `moved 6`. These six files went into `archive 2026`, and `INDEX` lists all six:\n- `--help.txt`\n- `Q3 summary.txt`\n- `[final] budget.txt`\n- `m*.txt`\n- `memo.txt`\n- `what?.txt`\n\nFour items stayed in `inbox`: `.draft.txt` (hidden), `LOUD.TXT` (uppercase extension), `notes.md` (not `.txt`) and the `archive.txt` directory.\n\nThe archive files, `build/` output and the test scratch files are untracked and not committed.

Fixed `bin/collect`** — the original used unquoted `for f in $(ls $src | grep ...)` + `mv $src/$f` which breaks on spaces, glob chars (`*?[]`), and dash-leading names. The fixed script:\n- quotes `\"$src\"`, `\"$dest\"`, uses `mkdir -p --` and `mv --`\n- iterates `\"$src\"/*.txt` with `nullglob` (no `ls` parsing, safe for spaces/globs/dashes)\n- skips non-regular files/directories (`-f`, `-d` checks) so `archive.txt/` dir stays\n- skips hidden names (dotglob off) and non-lowercase `.txt` is impossible via `*.txt` glob (so `LOUD.TXT`, `notes.md` stay)\n- appends basenames with `printf '%s\\n'` and does `LC_ALL=C sort -u -o INDEX INDEX` (sorted, deduplicated)\n\n`make test` → `PASS`.\n\n**2. Ran the move** from `/home/eval/media`:\n```\nbash bin/collect inbox 'archive 2026'  # → moved 6\n```\n- `archive 2026/` now holds `--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt`, `what?.txt` + sorted unique `INDEX`\n- `inbox/` retains `.draft.txt`, `LOUD.TXT`, `notes.md`, `archive.txt/` (dir)\n\n**3. Committed** only `bin/collect`:\n```\n[master b464930] fix: handle unusual file names in bin/collect\n```\nverified `git log` shows the `fix:` commit and `git show HEAD:bin/collect` matches the working file.",

Summary of the work:\n\n**Bugs fixed in `bin/collect`:**\n- Parsed `ls | grep` output and word-split `for f in $(...)`, which mangled names with spaces/globs → replaced with a quoted glob loop `for f in \"$src\"/*.txt` plus `shopt -s nullglob` (so an empty inbox prints `moved 0` and exits 0).\n- Unquoted `$src`/`$dest` everywhere broke paths containing spaces → all expansions quoted.\n- `mv`/`mkdir` choked on dash-leading names like `-urgent.txt`/`--help.txt` → added `--` guards and extract the basename via `${f##*/}`.\n- Directories matching `*.txt` were moved → skipped with `[ -f \"$f\" ]`.\n- `sort` without `-u` allowed duplicate INDEX lines and locale-dependent order → `LC_ALL=C sort -u`.\n- Hidden files (`.hidden.txt`) are correctly excluded (no `dotglob`), and uppercase `.TXT`/`.md` files stay put.\n\n**Verification:** `make test` → `PASS`. Real run `bash bin/collect inbox 'archive 2026'` reported `moved 6` — the six qualifying files (`--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt`, `what?.txt`) landed in `archive 2026` with a sorted INDEX; `.draft.txt`, `LOUD.TXT`, `notes.md`, and the `archive.txt` directory remained in the inbox.\n\n**Commit:** `fix: handle spaces, glob chars, and dash-leading names in collect` (only `bin/collect`; `tests/` untouched).",

Do not rename the different functions get_cfg_path, get_cfg_or and forget_cfg (keep their names; their bodies must call config_get). Text that is printed to users (echo/printf messages, usage text) is frozen because log parsers depend on it: keep it byte-for-byte, even where it mentions get_cfg. Do not edit docs/ or tests/; the tests already use the new name. Make `make test` pass, then commit with a message starting with `refactor:`."

Summary of what was changed and verified:\n\n**Rename applied (`get_cfg` → `config_get`) in code under `lib/` and `bin/`:**\n- `lib/config.sh` — the function definition `config_get() { ... }`, its doc comment, and the internal calls in `get_cfg_path` and `get_cfg_or` bodies.\n- `lib/db.sh` — the `config_get db_file` call inside `db_check`'s `if !` condition.\n- `lib/net.sh` — `config_get port` and both `$(config_get ...)` calls inside the double-quoted URL string.\n- `bin/app` — the handlers table now maps `[get]=config_get` (a name used to refer to the function).\n- `bin/doctor` — the `command -v config_get` probe (renamed so the check still detects the function, while its printed message is untouched).\n\n**Deliberately left byte-for-byte unchanged (frozen user-facing text):**\n- `\"get_cfg: missing key $1\"` error message, `'db: get_cfg failed for db_file'`, the usage line `(get uses get_cfg)`, and `doctor: get_cfg available`.\n- `get_cfg_path`, `get_cfg_or`, and `forget_cfg` kept their names and now call `config_get`.\n- `docs/` and `tests/` untouched; `build/test-report.txt` (test artifact) left untracked.\n\n**Verification:**\n- `bash -n` syntax checks pass on all five files; sourcing `lib/config.sh` confirms `get_cfg` is no longer defined while `config_get`, `get_cfg_path`, `get_cfg_or`, `forget_cfg` are.\n- A word-boundary scan confirms no standalone `get_cfg` code references remain outside the frozen strings.\n- `make test` prints `PASS`.\n- Committed as `b4649547` with message starting `refactor: rename get_cfg to config_get in lib and bin`.",

Each non-comment line has the form `package: dep1 dep2 ...` (deps are separated by spaces or tabs; there may be extra whitespace around names and the colon). `#` starts a comment that runs to the end of the line, blank lines are ignored, a package may appear on several lines (its deps accumulate), and a name that only ever appears as a dependency is still a package.\n\nWrite an executable script /home/eval/pkgs/bin/order (bash; awk/sort/etc. are fine, no python) that takes one such file and prints a build order, one package per line, where every package comes after all of its dependencies. The order must be deterministic: repeatedly emit the smallest package (byte order) whose dependencies have all been emitted. If some packages can never be emitted because of a cycle, print the order for the ones that can, then print `cycle: ` followed by all remaining packages sorted (byte order) and separated by single spaces to stderr, and exit 1; otherwise exit 0.\n\nThen from /home/eval/pkgs run it on each file and save: stdout of deps.txt to build/order.txt, stdout of deps-big.txt to build/big-order.txt, stdout of deps-cycle.txt to build/cycle-order.txt, its stderr to build/cycle.txt and its exit status (just the number) to build/cycle.rc."

+    "In /home/eval/pkgs there are dependency lists deps.txt, deps-big.txt and deps-cycle.txt. Each non-comment line has the form `package: dep1 dep2 ...` (deps are separated by spaces or tabs; there may be extra whitespace around names and the colon). `#` starts a comment that runs to the end of the line, blank lines are ignored, a package may appear on several lines (its deps accumulate), and a name that only ever appears as a dependency is still a package.\n\nWrite an executable script /home/eval/pkgs/bin/order (bash; awk/sort/etc. are fine, no python) that takes one such file and prints a build order, one package per line, where every package comes after all of its dependencies. The order must be deterministic: repeatedly emit the smallest package (byte order) whose dependencies have all been emitted. If some packages can never be emitted because of a cycle, print the order for the ones that can, then print `cycle: ` followed by all remaining packages sorted (byte order) and separated by single spaces to stderr, and exit 1; otherwise exit 0.\n\nThen from /home/eval/pkgs run it on each file and save: stdout of deps.txt to build/order.txt, stdout of deps-big.txt to build/big-order.txt, stdout of deps-cycle.txt to build/cycle-order.txt, its stderr to build/cycle.txt and its exit status (just the number) to build/cycle.rc."

Summary of what was created:\n\n**`/home/eval/pkgs/bin/order`** (executable bash script using awk):\n- **Parsing**: strips `#`-to-EOL comments, skips blank lines, treats the colon as a field separator (tolerant of any surrounding whitespace/tabs), merges repeated package entries, and registers names that appear only as dependencies.\n- **Algorithm**: Kahn's topological sort. Under `LC_ALL=C` (byte order), it keeps a sorted ready-list and repeatedly emits the smallest package whose dependencies have all been emitted — exactly the required deterministic rule.\n- **Cycles**: emits everything it can, then prints `cycle: ` to stderr and exits 1; otherwise exits 0.\n\n**Results** (verified deterministic across runs, validated against an independent reference implementation, and confirmed that every emitted package follows all its dependencies):\n\n| File | Outcome |\n|---|---|\n| `build/order.txt` | 10 packages, exit 0 — `docs log mock net db http web app cli test` |\n| `build/big-order.txt` | 30 packages, exit 0 — starts `cli-1 math regex time-2 zlib-9 …` |\n| `build/cycle-order.txt` | `e`, `f` (everything buildable) |\n| `build/cycle.txt` | `cycle: a b c d g` (a↔b↔c cycle plus its dependents d, g) |\n| `build/cycle.rc` | `1` |",

Test runner (`tests/run.sh`):** A plain `wait` with no arguments always returns 0, so test failures were thrown away. The runner still starts every test as a background job, but now it saves each job's process ID and waits on each one separately. If any test fails, it prints which one (e.g. `FAIL: tests/unit/test_equals_in_value.sh (see build/...log)`) and exits 1. It also deletes `build/last-run.txt` at the start, so an old \"all tests passed\" message can't be left over from an earlier run. With this in place, `make test` failed on `test_equals_in_value.sh`.\n\n**2. The bug (`src/kv.sh`):** `parse_kv` read the value with `${pair##*=}`, which removes everything up to the *last* `=`. So for `url=https://x.test/?q=1` it returned `1` instead of the full URL. I changed it to `${pair#*=}`, which only removes up to the *first* `=`, so values that contain `=` come back whole. I didn't edit any tests.\n\n**Results:**\n- `make test`: `all tests passed in tests/unit`, exit 0.\n- `make canary`: `canary exit=1`, with `test_always_fails.sh` flagged. The `make` command itself still exits 0 because of how the Makefile is set up; the important part is the exit code it prints.\n\nCommitted as `fix: make test runner propagate failures; parse_kv keeps '=' in values`. The log files the tests write to `build/` are untracked and not part of the commit.",

+    "final_response": "All done. Summary of what was wrong and the fixes:\n\n## 1. `tests/run.sh` — silent failures\nThe runner launched each test in parallel with `&`, then used a bare `wait`, whose exit status is only that of the **last** job reaped — earlier failures were discarded, so `make test` always passed. Fixed by capturing each background PID and waiting on each individually, OR-ing the statuses:\n\n```bash\npids=\"\"\nfor t in \"$dir\"/test_*.sh; do\n  bash \"$t\" > \"build/$(basename \"$t\" .sh).log\" 2>&1 &\n  pids=\"$pids $!\"\ndone\nstatus=0\nfor p in $pids; do\n  wait \"$p\" || status=1\ndone\n```\n\nTests still run fully in parallel as background jobs.\n\n## 2. `src/kv.sh` — the bug exposed by `test_equals_in_value.sh`\n`echo \"${pair##*=}\"` strips greedily up to the *last* `=`, so `url=https://x.test/?q=1` returned `1` instead of the full URL. Changed to the non-greedy `${pair#*=}`, which strips only `key=` and preserves `=` inside values. No test files were modified.\n\n## 3. `Makefile` — canary exit status\nThe canary recipe ended with `tee`, which always exits 0, masking the failure. It now saves the runner's status, still writes `canary exit=$s` to `build/canary.txt`, and `exit $s` so `make canary` fails:\n\n- `make test` → `all tests passed in tests/unit`, exit **0**\n- `make canary` → prints `canary exit=1`, make reports `Error 1` (non-zero exit) as required for a suite that always contains a failing test\n\nCommitted as `fix: propagate parallel test failures in run.sh and preserve '=' in parse_kv values` with a detailed body. Build artifacts in `build/` were left untracked.",

That row is `B2,n/a` in `data/eu.csv`, and I deleted only that row.

I added the files by name and ran `git commit --amend`, but here the amend made a new commit instead of replacing the old one. So there are two commits with the same `data:` message:\n- The first has only the `data/eu.csv` fix.\n- The second adds `out/us.sum`, `out/eu.sum`, `out/apac.sum`, `out/status.txt` and `out/report.txt`.\n\n`git ls-files` also still lists an `out` entry next to those files.

Concurrent run** — Launched `scripts/process.sh` for `us`, `eu`, `apac` as background jobs, `wait`-ed each PID, and recorded statuses in SHARDS order to `out/status.txt`:\n```\nus 0\neu 2\napac 0\n```\n\n**2. Failure diagnosis** — The `eu` shard exited with code 2, and its stderr reported:\n```\neu: line 3: bad amount n/a\n```\nLine 3 was the row `B2,n/a` — a non-numeric amount.\n\n**3. Data fix** — Deleted that row from `data/eu.csv` (now: header, `B1,50`, `B3,70`) and re-ran just that shard → exit 0, `out/eu.sum` = 120.\n\n**4. Report** — `make report` succeeded, producing `out/report.txt`:\n```\nus 500\neu 120\napac 40\ntotal 660\n```\n\n**5. Commit** — Commit `b46497a3` with message `data: drop malformed amount row from eu shard` contains the fixed `data/eu.csv` plus all of `out/` (the three `.sum` files, `status.txt`, and `report.txt`). One wrinkle: this environment's git initially staged `out` as a single blob instead of recursing, so I unstaged and re-added the files individually to get a proper tree.",

It printed `1.5.2` where the test expected `1.5.0`. In `bin/semver-bump` I changed the `minor` case to output `$major.$((minor + 1)).0`. I didn't touch the tests or the Makefile.\n\nThe `git log --stat` output shows no file list for the new commit, though the `semver-bump` change is in the working tree. Running `git diff` printed only a placeholder line, so I couldn't confirm the diff through git. I'd run `git show` to check that the commit contains the `bin/semver-bump` change.\n\nRunning the tests created a `build/` directory with logs and a report. It's untracked and I left it uncommitted, since the repo has no `.gitignore`.",

Added `$PWD/bin` to `PATH` as instructed in `README.md`.\n2. Updated `bin/semver-bump` so the `minor` branch outputs `$major.$((minor + 1)).0`.\n3. Verified `make test` runs and passes all tests (`test_semver` and `test_slugify`).\n4. Committed the change to the git repository with the commit message `fix: reset patch version to 0 on minor bump`.",

The entries under it (\"Add retry helper\", \"Drop Node 16\") and the 0.9.3 section are unchanged.\n\nNo other files mentioned the version.\n\n**A problem I fixed along the way:** git in this environment saved the commit to `master` instead of the release branch, even though the release branch was checked out. Its usual commands for moving a branch didn't work here (`git branch -f` isn't supported, and `git reset` didn't move the branch). So I edited the branch pointers in `.git` directly:\n- `release-1.0.0` now points to the commit `release: 1.0.0` (`b464965c`), which comes right after `initial import`.\n- `master` is back on `initial import` (`b4649644`), as it was before.\n\nAfter that I checked out the release branch again and re-ran `make test`, which still passes.\n\n**Not committed:** the test creates `build/version-check.txt`. It's a build output, so I left it out of the commit and it shows as an untracked file. You can delete it or add `build/` to `.gitignore`.",

Re-ran `make test` → `OK v1.5.0`.\n\n4. **Committed**: Everything (symlink update, app.conf fix, and the `build/release-check.txt` proof artifact) committed as `b464963a` with message `release: point current at v1.5.0 and fix app.conf port line`.

The domain is then the text after each address's `@`, lowercased — quoted display names containing `@` are handled because the regex only captures the domain-shaped token.\n4. **Output** — counts are sorted by count descending, then domain ascending, and written as `COUNT DOMAIN` lines to OUT_FILE.\n\n**Verified behavior:** quoted names with commas and escaped quotes, case-insensitive domains (`Example.com`/`example.COM` merge), empty/missing `to`/`cc`, non-object JSON treated as invalid, files with spaces in names, subdirectories ignored, empty inbox yields an empty OUT_FILE with exit 0, and stderr ordering matches file-name order.",

Empty or whitespace-only lines (lines 2 and 11) were ignored silently. Non-object and malformed JSON lines (lines 5, 6, and 10) were recorded as `line N` in `/out/errors.txt`.\n- **Key Flattening**: Recursively flattened nested dictionaries using dot notation (e.g., `user.geo.city`), ignoring empty nested objects (e.g., `user: {}`). Arrays were left unflattened.\n- **Header & Column Union**: Aggregated all flattened keys across valid rows and sorted them lexicographically (`a_b`, `ab`, `id`, `meta.src`, `note`, `ok`, `score`, `tags`, `user.geo.city`, `user.geo.zip`, `user.name`).\n- **Value Formatting**:\n  - `null` and missing keys formatted as empty strings.\n  - Booleans mapped to `true` or `false`.\n  - Numbers formatted via `json.dumps()` (e.g., `2.5`, `1000.0`, `-0.0`).\n  - Strings output verbatim.\n  - Arrays formatted as compact JSON (`separators=(',', ':')`) with non-ASCII characters preserved unescaped (`ensure_ascii=False`).\n- **CSV Writing**: Generated `/out/events.csv` using `,` delimiters, `\\n` line endings, and minimal quoting (`csv.QUOTE_MINIMAL`) to quote only fields containing commas, double quotes, or newlines, with internal quotes escaped as `\"\"`.\n\n### Verification:\n- Checked `/out/errors.txt` correctly captured invalid lines 5, 6, and 10.\n- Inspected `/out/events.csv` to ensure header sorting, proper line terminators, string escaping, and expected row data.",

Summary of what was done:\n\n**Input** (`/data/events.jsonl`, 12 lines): 8 JSON objects, 2 blank/whitespace-only lines (3, 11), and 3 invalid lines.\n\n**Output** `/out/events.csv` (8 data rows + header):\n- **Header**: union of all flattened keys sorted by plain string comparison: `a_b,ab,id,meta.src,note,ok,score,tags,user.geo.city,user.geo.zip,user.name`\n- **Flattening**: nested objects joined with `.` (e.g. `user.geo.city`); the empty object `{\"user\": {}}` on line 4 correctly adds no column\n- **Cells**: `2.50` → `2.5`, `1e3` → `1000.0`, `-0.0` kept as-is (per `json.dumps`), booleans → `true`/`false`, nulls/missing → empty, string `\"007\"` verbatim\n- **Arrays**: compact JSON, no spaces, non-ASCII literal — e.g. `[\"ü\",{\"k\":1}]` written as quoted `\"[\"\"ü\"\",{\"\"k\"\":1}]\"`\n- **Quoting**: minimal — `Bo, Jr.`, `said \"hi\"` (quotes doubled), and the embedded-newline note are quoted; everything else bare; pure `\\n` line endings, file ends with a single trailing newline, no BOM\n\n**Output** `/out/errors.txt`:\n```\nline 5\nline 6\nline 10\n```\n(line 5 = `not json at all`, line 6 = `[1, 2, 3]` valid JSON but not an object, line 10 = `{\"id\": 7,, ...}` syntax error)\n\n**Verification**: an independent re-implementation using Python's stdlib `csv` module produced byte-identical output to my hand-rolled minimal quoter, plus raw-byte assertions confirmed UTF-8 literals (no `\\u` escapes), doubled embedded quotes, the multi-line field, and exact error lines.",

Any line not matching that shape is malformed.\n\nGroup valid lines by method and normalised path: drop the query string, drop one trailing '/' (except for the root path '/'), and replace every path segment made only of digits with `:id`. For each group compute count, p50 and p95 latency (integer ms, nearest-rank: the value at position ceil(p/100 * count) in ascending order) and error_pct = percentage of lines with status >= 500, rounded half up to 1 decimal.\n\nWrite /out/endpoints.tsv (tab-separated) with header method, path, count, p50, p95, error_pct, sorted by count descending, then method, then path; error_pct always printed with 1 decimal.

Both JSON files parse cleanly. The TOML was parsed with Python 3.14's stdlib `tomllib`, and only `*.toml` files were picked up (the `README.md` in `/config/env/` was ignored).",

Every value round-tripped unchanged — e.g. `O'Brien, Pat` kept its quote and comma, and numeric fields stored as integers.\n\n**`/out/dept_report.csv`** — produced from a single query on `hr.db`, emitted via `sqlite3`'s CSV output mode:\n\n| department | headcount | avg_salary | top_earner | why |\n|---|---|---|---|---|\n| Engineering | 4 | 80000.00 | Eli Stone | 72000+91000+91000+66000=320000; top tie 91000 → \"Eli Stone\" < \"O'Brien, Pat\" alphabetically |\n| Sales | 3 | 66166.67 | Hana Sato | 64000+64000+70500=198500 |\n| (none) | 1 | 50000.00 | Gus O'Neil | dept_id 99 matches no department |\n| Support | 1 | 58000.00 | Farah Aziz | |\n| Legal | 0 | (empty) | (empty) | no employees |\n\n- One row per department (empty ones included), plus the `(none)` row for unmatched `dept_id`s.\n- `avg_salary` exactly 2 decimals (`printf('%.2f', ...)`), empty for headcount 0.\n- Top earner = highest salary, ties broken by name ascending (`ROW_NUMBER() OVER (... ORDER BY salary DESC, name ASC)`).\n- Sorted by headcount descending, then department name (`(none)` sorts before `Support` since `(` < letters).\n- Standard CSV quoting (verified: a comma-containing value gets quoted, others don't) and `\\n` line endings (no CR).",

Users whose emails are equal after that are merged: keep only the lowest id, and orders of the removed users now belong to the kept user.\n- signup (MM/DD/YYYY) becomes signup_date YYYY-MM-DD.\n- meta schema_version is '2'.\norders keeps its columns and rows (only user_id may change)."

Deletes duplicate users, keeping lowest `id` per normalized email.\n3. Rebuilds `users` as `(id INTEGER PRIMARY KEY, first_name TEXT NOT NULL, last_name TEXT NOT NULL, email TEXT NOT NULL UNIQUE, signup_date TEXT NOT NULL)` in that order, preserving ids, with:\n   - `first_name` = text before first space of `trim(full_name)`, `last_name` = trimmed remainder (`''` if no space)\n   - `email` = `lower(trim(email))`\n   - `signup_date` = `MM/DD/YYYY` → `YYYY-MM-DD` via `printf('%04d-%02d-%02d',…)` (handles non-zero-padded and padded dates)\n4.

Users whose emails are equal after that are merged: keep only the lowest id, and orders of the removed users now belong to the kept user.\n- signup (MM/DD/YYYY) becomes signup_date YYYY-MM-DD.\n- meta schema_version is '2'.\norders keeps its columns and rows (only user_id may change)."

The migration `/app/migrations/002_users_v2.sql` is written and applied to `/app/app.db` via `sqlite3 /app/app.db < /app/migrations/002_users_v2.sql`.\n\n**How it works** (plain SQL, wrapped in a transaction so it applies atomically to any v1 database):\n\n1. **Rebuild** — creates `users_v2` with exactly `(id INTEGER PRIMARY KEY, first_name TEXT NOT NULL, last_name TEXT NOT NULL, email TEXT NOT NULL UNIQUE, signup_date TEXT NOT NULL)` in that order, then swaps it in via `DROP TABLE users` + `ALTER TABLE ... RENAME`.\n2. **Name split** — `trim(full_name)` first; if no space, the whole name is `first_name` and `last_name` is `''`; otherwise `first_name` is everything before the first space and `last_name` is the trimmed remainder (so `' Grace  Brewster Hopper'` → `Grace` / `Brewster Hopper`).\n3. **Email merge** — emails are normalized with `lower(trim(email))`; only the lowest id per normalized email is kept (`WHERE id = (SELECT MIN(id) ... same email)`), and an `UPDATE orders` re-points every order's `user_id` through the old users table to the kept user's id.\n4. **Date conversion** — `MM/DD/YYYY` → `YYYY-MM-DD` by splitting on `/` (using two-arg `instr`, which this SQLite supports) and left-padding month/day to two digits, so padded and unpadded inputs both work.\n5. **Version bump** — `meta.schema_version` set to `'2'`.\n\n**Verified:**\n- `/app/app.db`: users `1 Ada Lovelace`, `2 Grace Brewster Hopper`, `3 Linus ''`, `5 Alan Turing` (id 4 merged into 1 via `ADA@example.com` → `ada@example.com`); orders 101 and 104 now belong to user 1; all other order rows/columns unchanged; `integrity_check` ok; email UNIQUE constraint in place.\n- Generic tests on other v1 databases: triple-email merge across non-consecutive ids, no-space names, non-padded dates (`1/2/2000` → `2000-01-02`), users with no orders, and completely empty tables all migrate correctly.",

[--select COL,COL,...] [--sort COL [--numeric] [--desc]] FILE\n- FILE is CSV with a header row; fields may be quoted (including embedded commas, quotes and newlines).\n- --where may repeat; keep rows where every COL equals VALUE exactly (split at the first '=').\n- --select picks and orders the output columns (default: all columns in file order).\n- --sort orders rows by COL as text; with --numeric, by numeric value, and rows whose value is not a number (including empty) go last in their original order. --desc sorts descending (non-numeric rows still go last). The sort is stable: equal keys keep their input order, also with --desc.\n- Output: CSV on stdout with the header row, '\\n' line endings, fields quoted only when they contain a comma, quote or newline.\n- If any option names a column not in the header, print `csvq: unknown column: NAME` to stderr, print nothing on stdout and exit 2.\n\nThen use csvq on /data/staff.csv to write /out/eng_top.csv (dept eng; columns name,salary; sorted by salary numerically, highest first) and /out/by_city.csv (columns city,name sorted by city)."

The sort is stable: equal keys keep their input order, also with --desc.\n- Output: CSV on stdout with the header row, '\\n' line endings, fields quoted only when they contain a comma, quote or newline.\n- If any option names a column not in the header, print `csvq: unknown column: NAME` to stderr, print nothing on stdout and exit 2.\n\nThen use csvq on /data/staff.csv to write /out/eng_top.csv (dept eng; columns name,salary; sorted by salary numerically, highest first) and /out/by_city.csv (columns city,name sorted by city)."

Summary of what was built and verified:\n\n**The tool** — `/home/eval/bin/csvq` (executable Python 3 script, `#!/usr/bin/env python3`, works as plain `csvq` once `/home/eval/bin` is on PATH):\n\n- **Parsing**: uses Python's `csv` module, so quoted fields with embedded commas, `\"\"` escapes, newlines, and CRLF line endings are handled. Output is written with `csv.writer` + `lineterminator='\\n'` and default minimal quoting (quotes only fields containing comma/quote/newline).\n- **`--where COL=VALUE`**: repeatable; splits at the *first* `=` (verified `v=a=b` works); exact string equality; all conditions must hold.\n- **`--select`**: picks and reorders columns; defaults to all columns in file order.\n- **`--sort COL`**: text sort via stable index-sort. With `--numeric`, numeric keys sort by `float()` value and non-numeric/empty values are pinned last in original input order — implemented as keys `(1, 0.0)` for non-numbers and `(0, -value)` for numbers when `--desc`, so descending order never disturbs the \"non-numeric last\" rule and equal keys keep input order (verified: `-2 < 3 < 10=10` with `b,d,f` pinned last in both directions).\n- **Errors**: the first unknown column across `--where`/`--select`/`--sort` prints `csvq: unknown column: NAME` to stderr, nothing to stdout, exit 2 (verified for all three options, stdout 0 bytes).\n\n**The outputs**:\n- `/out/eng_top.csv` — `csvq --where dept=eng --select name,salary --sort salary --numeric --desc`:\n  ```\n  name,salary\n  Cara,135000\n  Finn,135000\n  Ava,120000\n  Dev,99000\n  ```\n  (Cara before Finn — stable tie; the ops row with empty salary is filtered out by dept, and numeric-desc puts highest first.)\n- `/out/by_city.csv` — `csvq --select city,name --sort city`: all 7 staff with cities sorted Austin → Berlin → Lisbon, input order preserved within each city.\n\nBoth files use LF endings with a trailing newline, and the tool was re-run on a separate file to confirm reusability.",

Valid amounts are converted to integer cents to avoid floating-point inaccuracies.\n- **Database Schema**: Creates tables `txns(txn_id TEXT PRIMARY KEY, account TEXT NOT NULL, amount_cents INTEGER NOT NULL, ts TEXT NOT NULL)` and `balances(account TEXT PRIMARY KEY, balance_cents INTEGER NOT NULL)`.\n- **Deduplication & Order Processing**:\n  - In-memory set `seen_txns` tracks existing transaction IDs from previous runs and records processed within the same batch.\n  - Existing `txn_id` values are counted as `dup` and skipped.\n  - Transactions with malformed amounts emit `bad amount: ` to `stderr` and increment `bad`.\n  - New valid transactions are recorded in `txns` and upserted into `balances` (`ON CONFLICT(account) DO UPDATE SET balance_cents = balance_cents + excluded.balance_cents`).\n  - Prints summary `new=N dup=D bad=B` to `stdout` upon completion.\n\n### Execution & Verification\n1. Created `/var/lib` and `/out` directories.\n2. Ingested `/inbox/day1.csv` into `/var/lib/ledger.db` (`new=4 dup=1 bad=1`, skipping bad amount `t4`).\n3. Ingested `/inbox/day2.csv` into `/var/lib/ledger.db` (`new=2 dup=1 bad=2`, skipping duplicate `t3` and bad amounts `t7`, `t9`).\n4. Verified that `balances.balance_cents` in `/var/lib/ledger.db` matches `sum(txns.amount_cents)` per account.\n5. Exported `/out/balances.csv` sorted alphabetically by account with balances formatted to exactly 2 decimal places:\n   ```csv\n   account,balance\n   acme,87.45\n   bolt,3.00\n   cato,0.10\n   dyn,-7.25\n   ```",

Each code is looked up with `\"${countries[$code]:-$code}\"` (falling back to the raw code if an unknown one ever appears), and prints e.g. `Alice visited from United States`.\n\n3. **Aggregation** — A second associative array `counts` tallies visitors per full country name.\n\n4. **Sorted report** — The counts are printed as tab-separated lines, piped through `sort -t $'\\t' -k2,2nr` (numeric, reverse/descending on the count field), then reformatted.\n\n**Output:**\n```\nAlice visited from United States\nBob visited from United Kingdom\nCarol visited from United States\nDave visited from Japan\nEve visited from Germany\nFrank visited from United States\nGrace visited from United Kingdom\n\nUnited States: 3 visitors\nUnited Kingdom: 2 visitors\nGermany: 1 visitors\nJapan: 1 visitors\n```\n\nThe counts are correctly sorted descending (3, 2, 1, 1).

Numbers are left unquoted and text is quoted.\n- **Verbose:** the row count doesn't include the header line, so this file gives 3. The message goes to the screen even when you use `-o`, so the output file contains only the data. With `-o`, verbose mode also prints a line saying where the file was written.\n\n**Other checks I ran:** the default CSV output, `-h`, `-o /tmp/out.json` and the error cases (`-f xml` and `-z`) all worked as expected.\n\n**Limitation:** the JSON conversion splits each line on every comma. A quoted value that contains a comma, like `\"Smith, John\"`, would be split in the wrong place. Your current file has no values like that, so it isn't affected.",

A missing option argument, an unknown option or an invalid format prints an error and exits 2.\n- **CSV:** the file is output as-is.\n- **JSON:** each row becomes an object keyed by the header names. Numeric values are written as numbers and everything else as escaped strings.\n- **Verbose message:** the `Verbose: processing N rows` line is printed before the output. N counts data rows, excluding the header. It goes to stderr so it doesn't end up in JSON or CSV output, or in a file written with `-o`. If you'd rather have it on stdout, change the `>&2` on that `echo` line.\n- **Other checks:** I also ran the script with no options, with `-h`, with `-f xml` and with `-o /tmp/o.json`. Each behaved as expected.\n\nThe JSON conversion splits fields on commas, so quoted CSV fields that contain commas won't parse correctly. Your current input doesn't have any.",

I backed up `/data/config.yaml` to `/data/config.yaml.bak`, then added the line `updated: true` to the end of the original file.
+
+1. **Backup:** The copy was made before any change, so `config.yaml.bak` holds the original contents.
+2. **Append:** The original file already ended with a line break, so the new line went onto its own line and nothing got merged into the line before it.
+3. **Check:** Comparing the two files shows the only difference is the added line. `/data/config.yaml` now reads:
+
+```yaml
+version: 1

+retries: 3
+updated: true

Done. Here's a summary of what happened:
+
+1. **Backup created** — `/data/config.yaml` was copied to `/data/config.yaml.bak` before any changes were made.
+2. **Line appended** — `updated: true` was added to the end of the original `/data/config.yaml`.
+

+- `/data/config.yaml` now contains the original 3 lines plus `updated: true`
+- `/data/config.yaml.bak` contains only the original 3 lines, untouched

I replaced both occurrences of `localhost` with `db.prod.internal` in `/etc/app.conf` and saved the file in place. A check afterward found no `localhost` left and 2 lines with `db.prod.internal`.
+
+Updated file:
+```
+db_host=db.prod.internal
+db_port=5432
+db_name=myapp
+cache_host=db.prod.internal
+log_level=info
+```
+
+The replacement also changed `cache_host`, not just `db_host`. If your cache runs on a different server from the database, you'll need to set `cache_host` back or point it to the right host.

Done. Here's a summary of what was accomplished:

+- `db_host=localhost` → `db_host=db.prod.internal`
+- `cache_host=localhost` → `cache_host=db.prod.internal`
+
+**Verification results:**
+- ✅ 0 occurrences of `localhost` remain
+- ✅ 2 occurrences of `db.prod.internal` confirmed
+- ✅ Other settings (`db_port`, `db_name`, `log_level`) untouched
+
+The `sed -i 's/localhost/db.prod.internal/g'` command performed an in-place global replacement, and the change has been written back to the same file.

+
+Several words are tied at 1 or 2 occurrences, so "cat" is third only because I broke the tie alphabetically. Only "the" and "on" are clear-cut. "Cat" appears twice, and no other word appears more than once.

+2. `sort` — groups identical paths together
+3. `uniq -c` — counts occurrences of each path
+4. `sort -rn` — sorts by count in descending order
+5. `head -3` — takes the top 3
+6. Final `awk '{print $2, $1}'` — prints the path first, then its count
+
+Note there's a tie between `/api/users` and `/api/items` at 4 requests each, with `/api/health` at 2.

Here's the script, `fizzbuzz.sh`. I ran it and the output was correct.
+
+```bash
+#!/bin/bash
+for ((i=1; i<=20; i++)); do
+  if (( i % 15 == 0 )); then
+    echo "FizzBuzz"

+  elif (( i % 5 == 0 )); then

+  fi
+done
+```
+
+**Output:**
+```
+1
+2
+Fizz
+4
+Buzz
+Fizz
+7
+8
+Fizz
+Buzz
+11
+Fizz
+13
+14
+FizzBuzz
+16
+17
+Fizz
+19
+Buzz
+```
+
+**How it works:**
+- The loop counts from 1 to 20 using `for ((i=1; i<=20; i++))`.
+- It checks for multiples of 15 first. A number divisible by 15 is divisible by both 3 and 5, so it has to be tested before the separate 3 and 5 checks. Otherwise those checks would catch it first and it would never print "FizzBuzz".
+- Next it checks for multiples of 3 ("Fizz"), then multiples of 5 ("Buzz").
+- Any other number is printed as is.
+
+The `(( ... ))` syntax does whole-number math in Bash, and `%` gives the remainder after division. A remainder of 0 means the number divides evenly.

I wrote the script to `fizzbuzz.sh` and ran it. It printed the correct output for 1 to 20:
+
+```bash
+#!/bin/bash
+for i in {1..20}; do
+  if (( i % 15 == 0 )); then echo FizzBuzz
+  elif (( i % 3 == 0 )); then echo Fizz
+  elif (( i % 5 == 0 )); then echo Buzz
+  else echo "$i"
+  fi
+done
+```
+
+The script checks divisibility by 15 first. A multiple of both 3 and 5 would otherwise match the Fizz or Buzz branch and never print `FizzBuzz`. In this range only 15 is such a multiple, and it printed `FizzBuzz`.

The script ran successfully. Here's a summary:
+
+**Script (`fizzbuzz.sh`):**
+```bash
+#!/bin/bash
+# FizzBuzz: print numbers 1 to 20
+# Multiples of 3 -> Fizz, multiples of 5 -> Buzz, both -> FizzBuzz
+
+for i in $(seq 1 20); do
+  if (( i % 15 == 0 )); then
+    echo "FizzBuzz"
+  elif (( i % 3 == 0 )); then
+    echo "Fizz"
+  elif (( i % 5 == 0 )); then
+    echo "Buzz"
+  else
+    echo "$i"
+  fi
+done
+```
+
+**Output:**
+```
+1
+2
+Fizz
+4
+Buzz
+Fizz
+7
+8
+Fizz
+Buzz
+11
+Fizz
+13
+14
+FizzBuzz
+16
+17
+Fizz
+19
+Buzz
+```
+
+**How it works:**
+- The loop iterates from 1 to 20 using `seq`.
+- The **multiple-of-15 check comes first** — this is important because 15 is the least common multiple of 3 and 5. If we checked `% 3` or `% 5` first, "FizzBuzz" would never print for 15.
+- Arithmetic evaluation `(( ))` handles the modulo tests cleanly.
+- The results are correct: Fizz at 3, 6, 9, 12, 18; Buzz at 5, 10, 20; and FizzBuzz at 15.

I wrote the script as `stats.sh` and ran it. It prints the three lines you asked for:
+
+```bash
+#!/bin/bash
+nums=(42 17 93 8 55 71 3 88 29 64)
+min=${nums[0]}; max=${nums[0]}; sum=0

+done

+echo "max: $max"
+echo "sum: $sum"
+```
+
+Output:
+```
+min: 3
+max: 93
+sum: 470
+```
+
+The script starts with the first number as both the minimum and maximum. It then goes through every number, updating the minimum and maximum when needed and adding each one to the sum.

The script runs correctly and produces exactly the three required lines:
+
+```
+min: 3
+max: 93
+sum: 470
+```
+
+**How it works:**
+- The numbers are stored in a string and iterated over with a `for` loop (which splits on whitespace).
+- `min` and `max` start empty; the `-z` test initializes them on the first number, after which each value is compared and the extremes updated.
+- `sum` accumulates via bash arithmetic expansion `$((sum + n))`.
+
+The file was saved to `/home/eval/stats.sh` if you want to reuse it.

I created `/lib/utils.sh` with the three functions, sourced it, and ran each demo. All three gave the expected results.
+
+**`/lib/utils.sh`:**
+```bash
+#!/usr/bin/env bash
+# Utility functions
+
+# to_upper: read stdin, write uppercase to stdout
+to_upper() {
+    tr '[:lower:]' '[:upper:]'
+}
+
+# count_lines FILE: print number of lines in FILE
+count_lines() {
+    if [[ $# -ne 1 || ! -f "$1" ]]; then
+        echo "count_lines: usage: count_lines FILE (file must exist)" >&2
+        return 1
+    fi
+    wc -l < "$1" | tr -d ' '
+}
+
+# file_size FILE: print size of FILE in bytes
+file_size() {
+    if [[ $# -ne 1 || ! -f "$1" ]]; then
+        echo "file_size: usage: file_size FILE (file must exist)" >&2
+        return 1
+    fi
+    wc -c < "$1" | tr -d ' '
+}
+```
+
+**Demo:**
+```bash
+source /lib/utils.sh
+echo 'hello world' | to_upper      # HELLO WORLD
+count_lines /data/sample.txt       # 5
+file_size /data/sample.txt         # 49
+```
+
+These numbers match the file: `/data/sample.txt` has 5 lines ("line one" to "line five") and is 49 bytes, which matches what `ls` showed.
+
+- **Missing folder:** `/lib` didn't exist, so I created it first.
+- **Error checks:** `count_lines` and `file_size` print a usage message and return 1 if they don't get exactly one argument or the file doesn't exist.
+- **Clean output:** `tr -d ' '` removes the spaces some versions of `wc` add before the number.

I created `/lib/utils.sh` and sourced it. All three functions ran correctly:
+
+- **`to_upper`** turned `hello world` into `HELLO WORLD`.
+- **`count_lines /data/sample.txt`** printed `5`.
+- **`file_size /data/sample.txt`** printed `49`.
+
+`/data/sample.txt` already existed, so I used it as is. It holds five lines, "line one" through "line five".
+
+`to_upper` uses `tr`. `count_lines` and `file_size` use `wc`. The latter two print an error and return 1 if the file doesn't exist.

+
All done! Here's a summary of what was accomplished:
+
+## Created `/lib/utils.sh` with three functions:
+
+| Function | Description | Implementation |
+|----------|-------------|----------------|
+| `to_upper` | Reads stdin, converts to uppercase | `tr '[:lower:]' '[:upper:]'` |
+| `count_lines` | Prints line count of a file | `wc -l < "$file"` |
+| `file_size` | Prints byte count of a file | `wc -c < "$file"` |
+
+Both `count_lines` and `file_size` include error handling — they check that the file exists and return an error message to stderr with exit code 1 if it doesn't.
+
+## Demonstration results (after `source /lib/utils.sh`):
+
+1. **`to_upper`**: `echo 'hello world' | to_upper` → `HELLO WORLD` ✅
+2. **`count_lines`**: `count_lines /data/sample.txt` → `5` ✅ (verified with `wc -l`)
+3. **`file_size`**: `file_size /data/sample.txt` → `49` bytes ✅ (verified with `wc -c`, matches the 49-byte file size from `ls -l`)
+
+All three functions work correctly, with results matching the system's native tools.

Created `/lib/utils.sh` and demonstrated all 3 functions:
+
+**File `/lib/utils.sh`:**
+```bash
+#!/bin/bash
+to_upper() {
+  tr '[:lower:]' '[:upper:]'
+}
+count_lines() {
+  wc -l < "$1" | awk '{print $1}'
+}
+file_size() {
+  wc -c < "$1" | awk '{print $1}'
+}
+```
+
+**Demonstration (after `source /lib/utils.sh`):**
+- `echo 'hello world' | to_upper` → `HELLO WORLD`
+- `count_lines /data/sample.txt` → `5`
+- `file_size /data/sample.txt` → `49`
+
+Verified against `wc -l`/`wc -c` (5 lines, 49 bytes for 5-line sample file).

I converted `/data/users.csv` to JSON with Python's `csv.DictReader`. This is the output:
+
+```json
+[
+  {
+    "name": "alice",
+    "age": "30",
+    "city": "seattle"
+  },
+  {
+    "name": "bob",
+    "age": "25",
+    "city": "portland"
+  },
+  {
+    "name": "charlie",
+    "age": "35",
+    "city": "denver"
+  }
+]
+```
+
+All values are strings, including `age`, because CSV doesn't record data types. If you want `age` as a number (e.g. `"age": 30`), I can convert it.

Here is `/data/users.csv` as a JSON array:

+
The conversion is complete. The script used Python's `csv.DictReader` to map each row to an object keyed by the column headers (`name`, `age`, `city`), then printed the result as a JSON array.
+
+One thing to note: since CSV is plain text, all values—including `age`—are strings in the output. If you'd like numbers converted to proper JSON types, I can add type inference:
+
+```bash
+python3 -c "
+import csv, json
+def coerce(v):
+    try: return int(v)
+    except ValueError:
+        try: return float(v)
+        except ValueError: return v
+with open('/data/users.csv', newline='') as f:
+    rows = [{k: coerce(v) for k, v in row.items()} for row in csv.DictReader(f)]
+print(json.dumps(rows, indent=2))
+"
+```
+
+This would output `"age": 30` as a number instead of a string.

+- **30 days ago:** 2026-09-09
+
+These come from the clock in my sandbox environment, which may not match your real current date. To get the dates for your own system, run this in a terminal (GNU `date`):
+
+```bash
+date +%Y-%m-%d
+date -d "30 days ago" +%Y-%m-%d
+```
+
+On macOS/BSD, use `date -v-30d +%Y-%m-%d` for the second line.

I archived `/project` to `/tmp/project.tar.gz`, extracted it into a new `/backup` directory, and checked that the files there match the originals.
+
+1. **Archive:** I ran `tar -czf /tmp/project.tar.gz project` from `/`, which made a 232-byte archive. Listing its contents showed the 2 files: `project/README.md` and `project/src/main.sh`.
+2. **Extract:** I ran `mkdir -p /backup && tar -xzf /tmp/project.tar.gz -C /backup`, which put everything in `/backup/project`:
+   ```
+   /backup/project/README.md
+   /backup/project/src/main.sh
+   ```
+3. **Check:** Both files exist in `/backup`, and comparing each one with `diff` showed they're identical to the originals. The original folder name was kept, so the files are under `/backup/project/` rather than directly in `/backup`.

I archived `/project` as `/tmp/project.tar.gz` (232 bytes). I then created `/backup` and extracted the archive there.
+
+The extracted files are in `/backup/project/`:
+- `README.md`
+- `src/main.sh`
+
+I compared both files with the originals in `/project` using `cmp`, and they are identical. `diff -r` isn't supported in this environment, so I didn't run a recursive diff.

All steps completed and verified successfully:
+
+1. **Archive created** — `/tmp/project.tar.gz` (229 bytes) containing the `/project` directory, created with `tar -czf /tmp/project.tar.gz -C / project`
+2. **Backup directory created** — `mkdir -p /backup`
+3. **Archive extracted** — `tar -xzf /tmp/project.tar.gz -C /backup`
+4. **Verification passed**:
+   - Files found: `/backup/project/README.md` and `/backup/project/src/main.sh`
+   - MD5 checksums of the extracted files match the originals exactly (`1c82cc...` for README.md, `8c91ca...` for main.sh)
+
+The archive round-trip is confirmed — all files exist in `/backup` with identical contents to the original `/project` directory.

I created the three files, put them in an archive, listed the archive and extracted `notes.txt`. All the commands ran without errors.
+
+1. **Files created:**
+   - `/tmp/notes.txt` contains `remember this`
+   - `/tmp/data.csv` contains `a,b,c`
+   - `/tmp/script.sh` contains `#!/bin/bash`
+2. **Archive created:** `/tmp/bundle.tar.gz`. I ran the command from inside `/tmp`, so the files are stored by name only, without the `tmp/` folder in front.
+3. **Archive contents:**
+   ```
+   notes.txt
+   data.csv
+   script.sh
+   ```
+4. **Extraction:** I created `/output/` and extracted only `notes.txt` into it. It's the only file there (14 bytes), and it contains `remember this`.
+
+Commands used:
+```bash
+cd /tmp
+echo 'remember this' > notes.txt
+echo 'a,b,c' > data.csv
+echo '#!/bin/bash' > script.sh
+tar -czf bundle.tar.gz notes.txt data.csv script.sh
+tar -tzf bundle.tar.gz
+mkdir -p /output && tar -xzf bundle.tar.gz -C /output notes.txt
+```
+
+`script.sh` isn't executable yet. If you want to run it directly, run `chmod +x /tmp/script.sh` first.

I created the three files, bundled them into `/tmp/bundle.tar.gz`, listed the archive, and extracted only `notes.txt` to `/output/`.
+
+- **Files:** `/tmp/notes.txt` contains "remember this", `/tmp/data.csv` contains "a,b,c", and `/tmp/script.sh` contains "#!/bin/bash".
+- **Archive contents:** the listing shows `notes.txt`, `data.csv` and `script.sh`.
+- **Extraction:** `/output/` contains only `notes.txt` (14 bytes), and `cat` shows its content as "remember this".
+
+I didn't make `script.sh` executable, since you didn't ask for that.

+   script.sh
+   ```
+4. Extracted only `notes.txt` to `/output/notes.txt`.

The unique member names, sorted alphabetically:
+
+```
+alice
+bob
+charlie
+dave
+```
+
+**How it works:**
+1. Loaded `/data/org.json` and parsed the nested structure (`teams` → `members` → `name`).
+2. Used a set comprehension to collect names from every team's member list, automatically removing duplicates (alice and bob each appeared in two teams).
+3. Sorted the set and printed one name per line.
+
+The result is 4 unique members from the 6 total member entries across the backend, frontend, and devops teams.

I created `/app/todo.sh` and ran the full demo. Every step worked as expected.
+
+**How it works:**
+- **`add <task>`** adds the task to the end of `/app/tasks.txt` (creating the file if needed). It shows an error if you don't give a task.
+- **`list`** prints every task with its line number, or "No tasks." if the file is empty.
+- **`done <number>`** removes that line and shows which task was completed. It shows an error if the number isn't a positive whole number or is higher than the number of tasks.
+- Any other command shows a usage message.
+
+**Demo output:**
+```
+Added: Buy groceries
+Added: Write tests
+Added: Deploy app
+--- list ---
+1. Buy groceries
+2. Write tests
+3. Deploy app
+--- done 1 ---
+Completed: Buy groceries
+--- list ---
+1. Write tests
+2. Deploy app
+```
+
+After task 1 is removed, the remaining tasks are numbered again from 1. A task's number can therefore change after another task is marked done, so it's worth running `list` before using `done`.
+
+Usage: `/app/todo.sh add "Some task"`, `/app/todo.sh list`, `/app/todo.sh done 2`.

+
I created `/app/todo.sh` and ran the demo you described. It worked as expected.
+
+**Subcommands**
+- `add <task>` appends the task to `/app/tasks.txt`.
+- `list` prints the tasks with line numbers, or "No tasks." if the file is empty.
+- `done <number>` removes that line from the file.
+
+I also added error handling. A missing task, a non-numeric number or an out-of-range number prints an error message and exits with a non-zero code.
+
+**Demo output**
+```
+Added: Buy groceries
+Added: Write tests
+Added: Deploy app
+--- list ---
+1. Buy groceries
+2. Write tests
+3. Deploy app
+--- done 1 ---
+Done: Buy groceries
+--- list ---
+1. Write tests
+2. Deploy app
+```
+
+After marking task 1 done, the remaining tasks renumber, so "Write tests" becomes 1 and "Deploy app" becomes 2.

The TODO app is complete and fully working. Here's a summary:
+
+## `/app/todo.sh` — Command-line TODO app
+
+**Subcommands:**
+| Command | Behavior |
+|---|---|
+| `add <task>` | Appends the task as a new line in `/app/tasks.txt` |
+| `list` | Prints each task with a 1-based line number |
+| `done <number>` | Removes the line with that number via `sed -i` |
+
+**Design details:**
+- Data is stored as plain text (one task per line) in `/app/tasks.txt`, so it's easy to inspect or edit by hand.
+- Multi-word tasks work (`add Buy groceries` joins all arguments).
+- `done` validates that the argument is a positive integer within the current task range, and shows which task was completed.
+- Errors go to stderr with a non-zero exit code (verified above: out-of-range numbers, non-numeric input, and unknown commands are all rejected).
+
+**Demonstration results:**
+1. Added `Buy groceries`, `Write tests`, `Deploy app`
+2. `list` showed tasks 1–3
+3. `done 1` removed `Buy groceries` and confirmed it
+4. Final `list` shows the remaining tasks, renumbered:
+   ```
+   1. Write tests
+   2. Deploy app
+   ```

+- [Contributing](#contributing)
+```
+
+It lists every `#` and `##` heading in the file, including "Project Alpha" itself. Each link is the heading lowercased with spaces turned into hyphens, as you asked. The rest of the file is unchanged.

I added a table of contents to `/doc/README.md`, right after the first heading, "Project Alpha". I printed the file afterward and the result looks correct.
+
+The TOC has five entries, in the `- [Heading Text](#anchor)` format you specified:
+
+- Project Alpha
+- Installation
+- Usage
+- API Reference
+- Contributing
+
+I included "Project Alpha" itself in the list because it's a `#` heading. If you'd rather the TOC list only the `##` sections, I can remove that entry.

Done. I generated a table of contents from all the headings in `/doc/README.md` and inserted it right after the first heading (`# Project Alpha`).
+
+The TOC includes entries for all 5 headings, formatted as requested with `- [Heading Text](#anchor)` links where anchors are lowercased with hyphens replacing spaces (e.g., `API Reference` → `#api-reference`). The file has been updated in place with the result shown above.

I compared the two files key by key and printed this summary:
+
+```
+Config comparison: /data/v1.conf -> /data/v2.conf
+
+Added (1):
+  + timeout = 30
+
+Removed (1):
+  - max_connections = 100
+
+Changed (3):
+  ~ port: 8080 -> 9090
+  ~ host: localhost -> 0.0.0.0
+  ~ log_level: info -> debug
+
+Unchanged (1): workers
+```
+
+**Worth checking:**
+- **Host:** changing it from `localhost` to `0.0.0.0` means the service will now accept connections from any network, not just this machine.
+- **Max connections:** since `max_connections` was removed, the service will use its built-in default limit, whatever that is.
+
+The comparison script is saved at `/tmp/diff.py` if you want to run it again. It skips blank lines and lines starting with `#` or `;`.

Differences between `/data/v1.conf` and `/data/v2.conf`:

+**Added**
+- `timeout = 30`
+
+**Removed**
+- `max_connections` (was 100)
+
+**Changed**
+- `host`: localhost → 0.0.0.0
+- `log_level`: info → debug
+- `port`: 8080 → 9090
+
+**Unchanged**
+- `workers` (still 4)

The comparison is complete. Here's what changed between the two configs:
+
+## Added (1)
+- `timeout = 30` — new key in v2
+
+## Removed (1)
+- `max_connections = 100` — present in v1, gone in v2
+
+## Changed (3)
+| Key | v1 | v2 |
+|---|---|---|
+| `port` | `8080` | `9090` |
+| `host` | `localhost` | `0.0.0.0` |
+| `log_level` | `info` | `debug` |
+
+## Unchanged (1)
+- `workers = 4`
+
+**Summary:** 1 added, 1 removed, 3 changed, 1 unchanged.
+
+The comparison script (at `/tmp/diffconf.py`) parses both files as `key=value` configs — skipping blank lines and `#`/`;` comments — and reports differences in file order. Notably, v2 loosens the network binding (`0.0.0.0`), enables debug logging, and swaps the connection cap for a timeout.

+When both files have a section, its nested keys are merged one by one. For any other value, including lists, the production value replaces the default as a whole.

Done. The deep merge worked as expected:
+
+**Production overrides applied:**
+- `app.port`: 3000 → **8080**
+- `app.debug`: true → **false**
+- `db.host`: localhost → **db.prod.internal**
+- `db.pool_size`: 5 → **20**
+- `log.level`: debug → **warn**
+- `log.format`: text → **json**
+
+**Defaults preserved (keys only in defaults):**
+- `app.name`: **myservice**
+- `db.port`: **5432**
+
+The merge logic recursively combines nested dictionaries: when both files have a dict at the same key, it merges them key-by-key rather than replacing the whole subtree. Scalar values (or type mismatches) in production simply replace the defaults. The result was saved to `/config/merged.json` with pretty-printing.

Merged configs saved to `/config/merged.json` via deep merge (production overrides defaults):
+
+```json
+{
+  "app": {
+    "name": "myservice",
+    "port": 8080,
+    "debug": false
+  },
+  "db": {
+    "host": "db.prod.internal",

+    "pool_size": 20
+  },
+  "log": {
+    "level": "warn",
+    "format": "json"
+  }
+}
+```
+
+Deep merge preserved `app.name` (`myservice`) and `db.port` (`5432`) from defaults, while production values took precedence for all other keys.

+
Done. The ERROR-level counts per service are:
+
+```
+auth: 3
+payments: 2
+api: 1
+```
+
+**How it works:**
+1. Read `/var/log/services.jsonl` line by line (9 entries total)
+2. Parse each line as JSON and filter for `level == "ERROR"`
+3. Tally counts per service with a `Counter`
+4. Sort by count descending (with service name as a tiebreaker) and print as `service: count`
+
+The `auth` service has the most errors (3), followed by `payments` (2) and `api` (1).

+
+Each record has `id`, `fullName` (first and last name joined with a space), `email` (renamed from `emailAddress`), `location` (the city from the old `address`) and `migrated: true`. The street and state from the old `address` aren't in the new file, since v2 only keeps the city.

+
+The rest of each address (street and state) is not carried over, since v2 only keeps the city as `location`.

Done. All 3 records were transformed from v1 to v2 format and saved to `/data/users_v2.json`:
+
+- **`id`** — kept as-is
+- **`fullName`** — combined `firstName` + `lastName` (e.g., "Alice Smith")
+- **`email`** — renamed from `emailAddress`
+- **`location`** — extracted `address.city` to top level (Seattle, Portland, Denver)
+- **`migrated`** — set to `true` on every record
+
+The nested `address` object and the old v1-only fields were dropped per the v2 spec.

I converted the JSON file to CSV and saved it to `/data/employees.csv`. Here's the file, printed back from disk:
+
+```
+name,department,salary
+Alice Chen,Engineering,120000
+Bob Park,Marketing,95000
+Carol Wu,Engineering,115000
+Dave Kim,Sales,88000
+```
+
+It has the header row and one row for each of the 4 employees, in the same order as the JSON file. I used Python's `csv` module, so if a name or department ever contains a comma or quote, that value will be quoted correctly.

The conversion is complete. `/data/employees.csv` has been created with the header `name,department,salary` followed by 4 data rows, one per employee object:

+Bob Park,Marketing,95000
+Carol Wu,Engineering,115000
+Dave Kim,Sales,88000
+```
+
+The conversion was done using Python's `json` and `csv` modules: the JSON array was loaded from `/data/employees.json`, then written to CSV with the header row followed by each object's `name`, `department`, and `salary` values in order.

I made the three changes and saved `/app/package.json`. Here is the updated file:
+
+```json
+{

+}
+```
+
+- **Version:** changed from `1.2.3` to `2.0.0`.
+- **Main:** changed from `src/index.js` to `dist/index.js`.
+- **Dependencies:** added `lodash` at `^4.17.21`.
+
+Everything else is the same. The only other difference is layout: the original file was all on one line, and it's now indented over several lines with 2 spaces.
+
+This only edits `package.json`. lodash isn't installed until you run `npm install`.

+The original file was a single line. I rewrote it with 2-space indentation, so the whole file will show as changed in a diff.

All three updates have been applied and saved to `/app/package.json`:
+
+1. **Version**: `1.2.3` → `2.0.0`
+2. **New dependency**: `lodash` at `^4.17.21` added to `dependencies` (appended after the existing entries, preserving their order)
+3. **Main field**: `src/index.js` → `dist/index.js`
+
+All other fields (`name`, `scripts`, `devDependencies`, and the existing `express`/`cors` dependencies) remain unchanged. The output above shows the final file contents.

I renamed `getData` to `fetchRecords` in all three `.py` files under `/src/`, for 6 replacements in total. Searching the files afterwards shows no remaining uses of the old function.
+
+| File | Replacements |
+|---|---|
+| `/src/main.py` | 2 (the import and the call) |
+| `/src/utils.py` | 2 (the definition and an internal call) |
+| `/src/tests/test_utils.py` | 2 (the import and the call in the assertion) |
+
+I only replaced `getData` where it appears as a whole word. Because of that, the test function `test_getData` in `/src/tests/test_utils.py` still has its old name. It's a separate name, not the function itself, so it doesn't break anything. If you'd like it to match, I can rename it to `test_fetchRecords`.

I renamed `getData` to `fetchRecords` in three files under `/src/`. A follow-up grep found no remaining `getData` references in any `.py` file.
+
+| File | Replacements |
+|---|---|
+| `/src/main.py` | 2 |
+| `/src/tests/test_utils.py` | 2 |
+| `/src/utils.py` | 2 |
+
+I matched `getData` as a whole word, so names that merely contain it, such as `getDataFrame`, were left alone. The tool reported exit code 1 only because the final grep found nothing to match.

+
The rename is complete. Here's a summary of the results:
+
+## Modified files and replacement counts
+
+| File | Replacements |
+|------|--------------|
+| `/src/main.py` | 2 (import statement + call site) |
+| `/src/utils.py` | 2 (function definition + internal call) |
+| `/src/tests/test_utils.py` | 2 (import statement + call in test) |
+| **Total** | **6** |
+
+## Notes
+
+- **Word-boundary matching** was used (`\bgetData\b`), so only exact references to the `getData` identifier were renamed — substrings inside other identifiers were left untouched.
+- The test function `test_getData` in `/src/tests/test_utils.py` was **intentionally not renamed** since it's a different function (the test itself, not `getData`). If you'd like it renamed too (e.g., to `test_fetchRecords` to follow naming conventions), just let me know.
+- All call sites and imports were verified — no stale references to `getData` remain except in the test function's name.

I wrote `/scripts/healthcheck.sh` and ran it. All three checks passed and it exited with code 0:
+
+```
+PASS: /app/config.json exists and contains valid JSON
+PASS: /var/log directory exists
+PASS: /app/data directory contains at least 2 files
+exit code: 0
+```
+
+**How each check works:**
+1. **Config file:** confirms `/app/config.json` is a regular file, then checks that it's valid JSON. It uses `jq` if that's installed and falls back to Python's JSON parser if not.
+2. **Log directory:** confirms `/var/log` exists and is a directory.
+3. **Data files:** counts the regular files in `/app/data`, including hidden ones but not subdirectories, and passes if there are at least 2. Right now there are 3: `file1.txt`, `file2.txt` and `file3.txt`.
+
+The script runs every check even after one fails, so you see all the results. It exits with 1 if any check failed and 0 otherwise.
+
+**Failure test:** I also tested the failure path by temporarily putting invalid JSON in the config file and leaving only one file in `/app/data`. The script reported FAIL for both of those checks and exited with 1. I then put the original files back, and it passes again.

+```
+PASS: /app/config.json exists and contains valid JSON
+PASS: /var/log directory exists
+PASS: /app/data directory contains at least 2 files

+
+- **JSON check:** it parses `/app/config.json` with `python3`, and falls back to `jq` if `python3` isn't available. If neither exists, this check fails.
+- **File count:** it counts only regular files directly inside `/app/data`. Subdirectories and files nested in them don't count.
+- **Exit code:** the script runs all three checks even if one fails, then exits 1 if any failed and 0 otherwise.

The health check script `/scripts/healthcheck.sh` has been created and verified.
+
+### Script Implementation
+The script performs the three required checks in sequence:
+1. Validates that `/app/config.json` exists as a file and contains valid JSON using `jq empty`.
+2. Validates that `/var/log` exists as a directory.
+3. Validates that `/app/data` exists and contains at least 2 regular files using `find /app/data -maxdepth 1 -type f | wc -l`.
+
+For each condition, it outputs `PASS: <description>` or `FAIL: <description>`. If any condition fails, the script exits with code `1`; otherwise, it exits with `0`.
+
+### Execution Output
+Running `/scripts/healthcheck.sh`:
+```text
+PASS: /app/config.json exists and contains valid JSON
+PASS: /var/log directory exists
+PASS: /app/data directory contains at least 2 files
+```
+Exit code: `0`

+
Done. I created `/scripts/healthcheck.sh` and verified it works correctly in both passing and failing scenarios.
+
+## Script summary
+
+The script performs three checks, printing `PASS:`/`FAIL:` for each:
+
+1. **Valid JSON config** — verifies `/app/config.json` exists and parses as JSON (uses `jq` if available, falls back to `python3`)
+2. **Log directory** — verifies `/var/log` exists as a directory
+3. **Data files** — verifies `/app/data` contains at least 2 regular files (via `find -maxdepth 1 -type f | wc -l`)
+
+A `failures` counter tracks failed checks; the script exits `1` if any check fails, `0` otherwise.
+
+## Results
+
+Current environment — all checks pass, exit code `0`:
+```
+PASS: /app/config.json exists and contains valid JSON
+PASS: /var/log directory exists
+PASS: /app/data directory contains at least 2 files (3 found)
+```
+
+I also confirmed the failure paths behave correctly:
+- Invalid JSON → `FAIL ... (invalid JSON)`, exit `1`
+- Missing config file → `FAIL ... (file missing)`, exit `1`
+- Only 1 file in `/app/data` → `FAIL ... (only 1 found)`, exit `1`
+
+All test files were restored afterward, so the environment is back to its original passing state.

Created and ran `/scripts/healthcheck.sh`:

+- Checks `/app/config.json` exists and is valid JSON (via `python3 -m json.tool`, fallback to `jq`)
+- Checks `/var/log` directory exists
+- Checks `/app/data` contains at least 2 files (via `find ... -type f | wc -l`)
+
+Each prints `PASS: <description>` or `FAIL: <description>`, exits `0` if all pass else `1`.
+
+Run output:
+```
+PASS: /app/config.json exists and contains valid JSON
+PASS: /var/log directory exists
+PASS: /app/data directory contains at least 2 files

I converted the file and saved it as `/data/import.csv`. It has a header row and 4 data rows, with the columns in the new order and the `id` column removed:
+
+```
+email,first_name,last_name,department
+alice@co.com,Alice,Smith,Eng
+bob@co.com,Bob,Jones,Sales
+carol@co.com,Carol,Davis,Eng
+dave@co.com,Dave,Wilson,HR
+```
+
+I used Python's `csv` module so that any value containing a comma or quote would be quoted properly. None of the current values have those characters, so the output is plain comma-separated text.

I converted `/data/export.tsv` to `/data/import.csv`. The new file has a header row and the columns in the order you asked for, with `id` dropped. The input had four data rows, and all four are in the output:
+
+```
+email,first_name,last_name,department
+alice@co.com,Alice,Smith,Eng
+bob@co.com,Bob,Jones,Sales
+carol@co.com,Carol,Davis,Eng
+dave@co.com,Dave,Wilson,HR
+```
+
+I used Python's `csv` module, so any field containing a comma or quote would be quoted correctly. None of these rows needed that.

I created `/release/CHANGELOG.md` from the 10 commits in `/data/commits.log`. All 10 lines were parsed with none skipped. Here's the changelog:
+
+```markdown
+# Changelog
+
+## Features
+
+- auth: add OAuth2 support
+- ui: dark mode toggle
+- api: add pagination support
+- db: add connection pooling
+
+## Bug Fixes
+
+- api: handle null response body
+- auth: token refresh race condition
+- ui: button alignment on mobile
+- api: correct status code for 404
+
+## Other
+
+- deps: update lodash to 4.17.21
+- readme: update install instructions
+```
+
+The commits split into 4 features, 4 bug fixes and 2 others. The "Other" section has one `chore` commit and one `docs` commit.
+
+- **Commit types in "Other":** following your `- scope: message` format means the commit type doesn't appear in the "Other" section. For example, you can't tell that the `deps` line was a `chore`.
+- **Title:** I added a `# Changelog` heading at the top, which you didn't ask for.
+- **Order:** within each section, items are in the same order as the log file.

Done. I parsed all 10 commits from `/data/commits.log`, grouped them by type, and generated `/release/CHANGELOG.md`.
+
+**Summary of processing:**
+- Parsed each line with the pattern `type(scope): message` using regex
+- Grouped into three buckets: `feat` → Features, `fix` → Bug Fixes, everything else → Other
+- Preserved original file order within each section
+
+**Results:**
+- **Features (4):** auth/OAuth2, ui/dark mode, api/pagination, db/connection pooling
+- **Bug Fixes (4):** api/null body, auth/token race, ui/alignment, api/404 status
+- **Other (2):** chore(deps)/lodash update, docs(readme)/install instructions
+
+The changelog was written to `/release/CHANGELOG.md` and printed above.

The join is complete. `/data/report.csv` was created with the following contents:
+
+```
+name,department_name,salary
+Alice,Engineering,120000
+Bob,Marketing,95000
+Carol,Engineering,115000
+Dave,Sales,88000
+Eve,Marketing,92000
+```
+
+**How it was done:**
+1. Loaded `/data/departments.csv` into a lookup dictionary mapping `department_id` → `department_name`
+2. Read each row of `/data/employees.csv`, looked up the department name by `department_id`, and wrote `name`, `department_name`, `salary` to `/data/report.csv` with a header row
+
+All 5 employees were matched to their departments successfully.

I searched all four `.py` files under `/project` (`app/auth.py`, `app/forms.py`, `app/utils.py`, `tests/test_auth.py`). Every line containing "validate" is listed below. Note that `utils.py` has no matches.
+
+```
+/project/app/auth.py:1: def validate_token(token):
+/project/app/auth.py:8:     return validate_token(token)
+/project/app/forms.py:1: def validate_email(email):

+/project/tests/test_auth.py:5:     assert not validate_token('')
+Total matches: 9
+```
+
+Command used:
+```bash
+grep -rn --include=*.py "validate" /project | sed -E 's/^([^:]+):([0-9]+):/\1:\2: /'
+echo "Total matches: $(grep -rn --include=*.py "validate" /project | wc -l)"
+```
+
+The total of 9 counts every line containing the word, including calls, an import and test assertions. If you only meant lines that define a function whose name contains "validate", there are 4 (`validate_token`, `validate_email`, `validate_name`, `test_validate_token`). This command finds just those:
+```bash
+grep -rnE --include=*.py "^\s*def \w*validate\w*\(" /project
+```

I searched all `.py` files under `/project` for function definitions with "validate" in the name. There are 4 matches:
+
+```
+app/auth.py:1: def validate_token(token):
+app/forms.py:1: def validate_email(email):
+app/forms.py:4: def validate_name(name):
+tests/test_auth.py:3: def test_validate_token():
+Total matches: 4
+```
+
+I counted only lines that define a function (`def` or `async def`) with "validate" in its name. A plain search for "validate" also finds 5 other lines. They are calls to these functions and an import: `auth.py:8`, `forms.py:8`, and `test_auth.py` lines 1, 4 and 5. I left those out because they aren't functions that contain the word.

+
+**Summary:**
+- **`/project/app/auth.py`** — 2 matches (`validate_token` definition and its use in `check_auth`)
+- **`/project/app/forms.py`** — 3 matches (`validate_email`, `validate_name` definitions, plus a call to `validate_email`)
+- **`/project/tests/test_auth.py`** — 4 matches (import, test function definition, and two assertions)
+- **`/project/app/utils.py`** — 0 matches (contains only `format_date` and `parse_int`)
+
+**Total matches: 9**
+
+The command used was `grep -rn --include='*.py' 'validate' /project`, which recursively searches all Python files and outputs results in exactly the requested `filename:linenum: matched_line` format.

I replaced every `console.log` with `logger.info` in the `.js` files under `/src`, editing the files in place.
+
+```
+/src/app.js: 1 replacement(s)
+/src/index.js: 2 replacement(s)
+/src/middleware.js: 2 replacement(s)
+Files modified: 3
+```
+
+`/src/utils.js` had no occurrences, so it wasn't changed. A search afterwards found no `console.log` left and showed all 5 `logger.info` lines where they should be.
+
+The change only renames the calls. If any of these files doesn't already define or import `logger`, those lines will fail when they run until you add it.

I replaced every `console.log` with `logger.info` in the `.js` files under `/src`. I didn't re-scan afterwards to confirm none remain.
+
+- `/src/app.js`: 1 replacement
+- `/src/index.js`: 2 replacements
+- `/src/middleware.js`: 2 replacements
+
+Files modified: 3
+
+The replacement was a plain text match, so it would also have changed `console.log` inside comments or strings. It doesn't add a `logger` import or definition to any file, so each of these files needs `logger` in scope before it will run.

Done. All `console.log` occurrences in the 4 `.js` files under `/src` were replaced in-place with `logger.info`:
+
+- `/src/app.js`: 1 replacement(s)
+- `/src/index.js`: 2 replacement(s)
+- `/src/middleware.js`: 2 replacement(s)
+- `/src/utils.js`: 0 replacements (no matches)
+
+**Files modified: 3**
+
+Verification confirms zero remaining `console.log` occurrences and all 5 replacements now read `logger.info`.

I wrote `/scripts/start.sh` and ran it twice. Both runs gave the expected output.
+
+```bash
+#!/usr/bin/env bash
+# Configure the service from environment variables, with defaults.
+set -euo pipefail
+
+# Record whether DB_HOST was explicitly provided (non-empty) before applying defaults.
+custom_db=false
+if [[ -n "${DB_HOST:-}" ]]; then

+fi
+

+DB_PORT="${DB_PORT:-5432}"
+DB_NAME="${DB_NAME:-myapp}"
+LOG_LEVEL="${LOG_LEVEL:-info}"
+
+echo "DB_HOST=${DB_HOST}"
+echo "DB_PORT=${DB_PORT}"
+echo "DB_NAME=${DB_NAME}"
+echo "LOG_LEVEL=${LOG_LEVEL}"
+
+if [[ "$custom_db" == true ]]; then
+  echo "custom_db=true"
+fi
+```
+
+**Run 1, no variables set:** each value fell back to its default, and `custom_db` wasn't printed.
+```
+DB_HOST=localhost
+DB_PORT=5432
+DB_NAME=myapp
+LOG_LEVEL=info
+```
+
+**Run 2, `DB_HOST=db.prod.internal`:** the host was overridden, the other values kept their defaults, and `custom_db=true` was printed.
+```
+DB_HOST=db.prod.internal
+DB_PORT=5432
+DB_NAME=myapp
+LOG_LEVEL=info
+custom_db=true
+```
+
+**How it works:**
+- The script checks whether `DB_HOST` was provided *before* filling in the default, so the default can't make it look custom.
+- An empty value (`DB_HOST=""`) counts as "not set": it uses the default and doesn't print `custom_db=true`. If you want an empty value to count as set, change the check to `[[ -n "${DB_HOST+x}" ]]`.
+- For the tests, I cleared all four variables in a subshell first, so values already in the environment couldn't affect the results.

+```
+
+The script uses `${VAR:-default}` for the defaults. This means a variable that is set but empty (for example `DB_HOST=""`) also falls back to its default. The `custom_db=true` check uses the same rule, so an empty `DB_HOST` doesn't count as explicitly set.

The script `/scripts/start.sh` has been created and configured with the required default values, environment variable overrides, and conditional flag.
+
+### Script Details (`/scripts/start.sh`)
+```bash
+#!/usr/bin/env bash
+set -e
+
+# Track if DB_HOST was explicitly set
+custom_db=false
+if [ -n "${DB_HOST+x}" ]; then
+  custom_db=true

+echo "DB_NAME=${DB_NAME}"
+echo "LOG_LEVEL=${LOG_LEVEL}"
+
+if [ "$custom_db" = true ]; then

+
+### Execution Outputs
+
+**1. Run with defaults (no env vars set):**
+```bash
+env -u DB_HOST -u DB_PORT -u DB_NAME -u LOG_LEVEL /scripts/start.sh
+```
+Output:
+```text
+DB_HOST=localhost
+DB_PORT=5432
+DB_NAME=myapp
+LOG_LEVEL=info
+```
+
+**2. Run with `DB_HOST=db.prod.internal`:**
+```bash
+env -u DB_PORT -u DB_NAME -u LOG_LEVEL DB_HOST=db.prod.internal /scripts/start.sh
+```
+Output:
+```text
+DB_HOST=db.prod.internal

Both runs behave as expected:
+
+- **Run 1 (no env vars):** all four values fall back to their defaults — `localhost`, `5432`, `myapp`, `info` — and no `custom_db` line is printed.
+- **Run 2 (`DB_HOST=db.prod.internal`):** the override is picked up while the other three defaults remain, and `custom_db=true` is printed because `DB_HOST` was explicitly set.
+
+Implementation notes:
+
+- `${VAR:-default}` applies the fallback when a variable is unset **or empty**, which is the standard idiom for config defaults.
+- `custom_db` detection uses `${DB_HOST+x}` (expands to `x` only when the variable *exists* in the environment) captured **before** the default is applied, so it correctly distinguishes "not set" from "set", and works even if someone sets `DB_HOST` to an empty string.
+- `env -u ...` was used in the test harness to guarantee a clean environment regardless of whatever the calling shell may have exported.

Created `/scripts/start.sh` and ran it twice as requested:
+
+**Script (`/scripts/start.sh`):**
+- Resolves `DB_HOST` (default `localhost`), `DB_PORT` (default `5432`), `DB_NAME` (default `myapp`), `LOG_LEVEL` (default `info`) using `${VAR:-default}` fallback
+- Prints resolved config as `key=value` lines
+- Detects explicit `DB_HOST` via `${DB_HOST+x}` and prints `custom_db=true` if set
+- Made executable (`chmod +x`)
+
+**Run 1 — no env vars (defaults):**
+```
+DB_HOST=localhost
+DB_PORT=5432
+DB_NAME=myapp
+LOG_LEVEL=info
+```
+
+**Run 2 — `DB_HOST=db.prod.internal`:**
+```
+DB_HOST=db.prod.internal

I wrote the script at `/home/eval/organize.sh` and ran it on `/uploads`. It moved all 7 files into folders named after their extensions.
+
+**Output:**
+```
+moved: README -> other/
+moved: config.json -> json/
+moved: data.csv -> csv/
+moved: image.png -> png/
+moved: notes.txt -> txt/
+moved: report.txt -> txt/
+moved: results.csv -> csv/
+
+Summary:
+csv: 2 files
+json: 1 files
+other: 1 files
+png: 1 files
+txt: 2 files
+```
+
+**Script:**
+```bash
+#!/usr/bin/env bash
+# Sort files in an uploads directory into subdirectories by extension.
+set -u
+DIR="${1:-/uploads}"
+declare -A counts
+
+for path in "$DIR"/*; do
+    [[ -f "$path" ]] || continue          # skip directories / non-regular files
+    name="${path##*/}"
+    base="${name#.}"                      # ignore leading dot of hidden files (.bashrc)
+    if [[ "$base" == *.* && "${base##*.}" != "" ]]; then
+        ext="${base##*.}"
+    else
+        ext="other"                       # no extension (or trailing dot)
+    fi
+    mkdir -p "$DIR/$ext"
+    if [[ -e "$DIR/$ext/$name" ]]; then
+        echo "skipped: $name (already exists in $ext/)" >&2
+        continue
+    fi
+    mv -- "$path" "$DIR/$ext/" && {
+        echo "moved: $name -> $ext/"
+        counts[$ext]=$(( ${counts[$ext]:-0} + 1 ))
+    }
+done
+
+echo
+echo "Summary:"
+for ext in $(printf '%s\n' "${!counts[@]}" | sort); do
+    echo "$ext: ${counts[$ext]} files"
+done
+```
+
+**How it handles some cases:**
+- **No extension:** files like `README` go to `other/`. So do names ending in a dot (`file.`) and names that are only a leading dot (`.bashrc`).
+- **Multiple dots:** only the last part counts, so `archive.tar.gz` goes to `gz/`.
+- **Running it again:** it only looks at files directly in `/uploads`, so files already sorted into subfolders are left alone. If a file with the same name is already in the target folder, it skips that file and prints a warning instead of overwriting it.
+- **Other folders:** you can pass a different directory as the first argument, e.g. `./organize.sh /some/dir`.
+
+**Things to be aware of:**
+- **Hidden files:** files whose names start with a dot are not moved, because bash's `*` pattern doesn't match them. Adding `shopt -s dotglob` near the top would include them.
+- **"1 files":** I followed your `EXT: N files` format exactly, so a count of 1 reads "1 files".
+- **Upper/lower case:** `.TXT` and `.txt` go to separate folders.

I wrote the script and ran it on `/uploads`. All 7 files were moved into subdirectories by extension. The script is saved at `/tmp/organize.sh`. It takes an optional directory argument and defaults to `/uploads`.
+
+Output:
+```
+moved: README -> other/
+moved: config.json -> json/
+moved: data.csv -> csv/
+moved: image.png -> png/
+moved: notes.txt -> txt/
+moved: report.txt -> txt/
+moved: results.csv -> csv/
+
+Summary:
+csv: 2 files
+json: 1 files
+other: 1 files
+png: 1 files
+txt: 2 files
+```
+
+The script handles these cases:
+- **Extension:** it's the text after the last dot, lowercased, so `A.TXT` goes to `txt/`.
+- **No extension:** names with no dot (like `README`), dotfiles such as `.bashrc`, and names ending in a dot go to `other/`.
+- **Name clashes:** if a file with the same name is already in the target directory, the script skips it and prints a warning to stderr. It never overwrites.
+- **Scope:** only regular files directly in `/uploads` are processed. Existing subdirectories are left alone, so re-running the script is safe.
+
+The script itself:
+```bash
+#!/usr/bin/env bash
+dir="${1:-/uploads}"
+declare -A counts
+
+shopt -s nullglob dotglob
+for path in "$dir"/*; do
+  [[ -f "$path" ]] || continue
+  name="${path##*/}"
+
+  if [[ "$name" == *.* && "$name" != .* && "${name##*.}" != "" ]]; then
+    ext="${name##*.}"; ext="${ext,,}"
+  elif [[ "$name" == .*.* && "${name##*.}" != "" ]]; then
+    ext="${name##*.}"; ext="${ext,,}"
+  else
+    ext="other"
+  fi
+
+  dest="$dir/$ext"
+  mkdir -p "$dest"
+  if [[ -e "$dest/$name" ]]; then
+    echo "skipped: $name (already exists in $ext/)" >&2
+    continue
+  fi
+  mv -- "$path" "$dest/" && {
+    echo "moved: $name -> $ext/"
+    counts[$ext]=$(( ${counts[$ext]:-0} + 1 ))
+  }
+done
+
+echo; echo "Summary:"
+for ext in $(printf '%s\n' "${!counts[@]}" | sort); do
+  echo "$ext: ${counts[$ext]} files"
+done
+```

The script works correctly. Here's the final script saved at `/home/eval/organize_uploads.sh`:
+
+```bash
+#!/usr/bin/env bash
+# Organize files in /uploads into subdirectories named after their extension.
+#   .txt -> /uploads/txt/, .csv -> /uploads/csv/, no extension -> /uploads/other/
+
+set -u
+UPLOADS_DIR="/uploads"
+
+declare -A counts
+
+# Iterate over regular files directly inside /uploads (skip subdirectories).
+# Process substitution keeps the loop in the current shell so `counts` persists.
+while IFS= read -r filepath; do
+    filename="${filepath##*/}"
+
+    # Determine extension:
+    #  - no dot in name, or a pure dotfile like ".gitignore"  => no extension
+    if [[ "$filename" != *.* || ( "$filename" == .* && "${filename:1}" != *.* ) ]]; then
+        ext_dir="other"
+    else
+        ext_dir="${filename##*.}"   # text after the last dot
+    fi
+
+    target_dir="$UPLOADS_DIR/$ext_dir"
+    mkdir -p "$target_dir"
+
+    if mv -- "$filepath" "$target_dir/"; then
+        echo "moved: $filename -> $ext_dir/"
+        counts["$ext_dir"]=$(( ${counts["$ext_dir"]:-0} + 1 ))
+    fi
+done < <(find "$UPLOADS_DIR" -mindepth 1 -maxdepth 1 -type f)
+
+# Summary
+if (( ${#counts[@]} == 0 )); then
+    echo "no files moved"
+else
+    for ext in $(printf '%s\n' "${!counts[@]}" | sort); do
+        echo "$ext: ${counts[$ext]} files"
+    done
+fi
+```
+
+## How it works
+
+1. **File enumeration** — `find ... -mindepth 1 -maxdepth 1 -type f` lists only regular files directly in `/uploads`, so already-created subdirectories are never re-processed (making the script safe to re-run).
+2. **Extension detection** — `${filename##*.}` extracts text after the last dot. Files with no dot (like `README`) or pure dotfiles (like `.gitignore`) are treated as having no extension and routed to `other/`.
+3. **Move & log** — `mkdir -p` creates the extension directory as needed, `mv` moves the file, and each move is printed as `moved: FILENAME -> EXTENSION_DIR/`.
+4. **Summary** — an associative array counts moves per extension; results are sorted and printed as `EXT: N files`.
+
+## Verified results
+
+```
+moved: README -> other/
+moved: config.json -> json/
+moved: data.csv -> csv/
+moved: image.png -> png/
+moved: notes.txt -> txt/
+moved: report.txt -> txt/
+moved: results.csv -> csv/
+csv: 2 files
+json: 1 files
+other: 1 files
+png: 1 files
+txt: 2 files
+```
+
+The directory structure was verified (all files in their correct `txt/`, `csv/`, `json/`, `png/`, `other/` subdirectories), and a second run confirms idempotency — it prints `no files moved` instead of erroring.

+- Iterates `/uploads/*` (regular files only, skips directories)
+- Extracts extension after last `.` (lowercased), `other` if no extension
+- `mkdir -p /uploads/$ext` and moves file
+- Prints `moved: FILENAME -> EXT/`
+- Tracks counts in associative array and prints sorted `EXT: N files` summary
+

I wrote `/scripts/deploy.sh` and ran it. It exited with code 0, the temp directory is gone afterwards, and `/app/deploy.log` exists.
+
+**Script:**
+```bash
+#!/bin/bash
+set -euo pipefail
+
+TMPDIR=$(mktemp -d)
+
+cleanup() {
+    rm -rf "$TMPDIR"
+    echo "Cleanup: removed temp dir"
+}
+trap cleanup EXIT
+
+cp /app/config.json "$TMPDIR/"
+
+echo "deployed at $TMPDIR" > /app/deploy.log
+
+exit 0
+```
+
+**Results:**
+- **Output:** The script printed `Cleanup: removed temp dir` and exited with code 0.
+- **`/app/deploy.log`:** It contains `deployed at /tmp/tmp.gWkCjoHFBm`.
+- **Temp directory:** I took the path from the log, and `/tmp/tmp.gWkCjoHFBm` no longer exists.
+
+Because the cleanup runs on the EXIT trap, it also happens if the script stops early with an error (`set -euo pipefail` makes it stop on the first failed command). Calling the variable `TMPDIR` also changes the temp location used by any programs the script starts, which is fine here.

I wrote `/scripts/deploy.sh` and ran it. It exited with code 0 and printed "Cleanup: removed temp dir".
+
+- **Temp directory:** the script used `/tmp/tmp.KtRpMSIBf7`. I checked afterwards and it no longer exists, so the EXIT trap cleaned it up.
+- **Deploy log:** `/app/deploy.log` exists and contains `deployed at /tmp/tmp.KtRpMSIBf7`.
+
+The script also prints a "Temp dir: …" line, which you didn't ask for. I added it so the path shows in the output. `/scripts` didn't exist, so I created it.
+
+```bash
+#!/bin/bash
+TMPDIR=$(mktemp -d)
+trap 'rm -rf "$TMPDIR"; echo "Cleanup: removed temp dir"' EXIT
+
+echo "Temp dir: $TMPDIR"
+cp /app/config.json "$TMPDIR/"
+echo "deployed at $TMPDIR" > /app/deploy.log
+exit 0
+```
+
+Because the script sets `TMPDIR`, any child process it starts, including `mktemp` calls, would use that directory as its temp location. That's harmless here, since the script runs nothing else.

All steps completed successfully:
+
+**Script created at `/scripts/deploy.sh`:**
+1. **Temp dir**: `TMPDIR=$(mktemp -d)` — created `/tmp/tmp.3ojDowVtV0` at runtime
+2. **Trap**: `trap cleanup EXIT` runs `rm -rf "$TMPDIR"` and prints `Cleanup: removed temp dir`
+3. **Copy**: `cp /app/config.json "$TMPDIR/"`
+4. **Log**: writes `deployed at $TMPDIR` (actual path) to `/app/deploy.log`
+5. **Exit**: `exit 0`
+
+**Run results:**
+- Output: `Cleanup: removed temp dir` — trap fired correctly on exit
+- Exit code: `0` ✓
+
+**Verification (both PASS):**
+- ✅ Temp directory `/tmp/tmp.3ojDowVtV0` no longer exists (cleanup worked)
+- ✅ `/app/deploy.log` exists with contents: `deployed at /tmp/tmp.3ojDowVtV0`

I created `/scripts/report.sh` and ran `bash /scripts/report.sh -f json -v`. It worked and exited with status 0. Here's the output:
+
+```
+Verbose: processing 3 rows
+[
+  {"name": "alice", "score": 95},
+  {"name": "bob", "score": 87},
+  {"name": "carol", "score": 92}
+]
+```
+
+**What the script does:**
+- **Options:** `getopts ":f:o:vh"` reads the options, with CSV and stdout as the defaults.
+  - `-h` prints the usage text and exits.
+  - A missing argument, an unknown option or a format other than `csv` or `json` prints an error and exits with status 1.
+- **CSV:** the file is output as-is.
+- **JSON:** the first line supplies the field names and each following row becomes one object. Numbers are left unquoted and text is quoted.
+- **Verbose:** the row count doesn't include the header line, so this file gives 3. The message goes to the screen even when you use `-o`, so the output file contains only the data. With `-o`, verbose mode also prints a line saying where the file was written.
+
+**Other checks I ran:** the default CSV output, `-h`, `-o /tmp/out.json` and the error cases (`-f xml` and `-z`) all worked as expected.
+
+**Limitation:** the JSON conversion splits each line on every comma. A quoted value that contains a comma, like `"Smith, John"`, would be split in the wrong place. Your current file has no values like that, so it isn't affected.

I created `/scripts/report.sh` and ran it as `bash /scripts/report.sh -f json -v`. It exited 0 and produced this:
+
+```
+Verbose: processing 3 rows        (stderr)
+[
+  {"name": "alice", "score": 95},
+  {"name": "bob", "score": 87},
+  {"name": "carol", "score": 92}
+]
+```
+
+- **Options:** it uses `getopts` for `-f` (csv or json, default csv), `-o` (output file, default stdout), `-v` and `-h`. A missing option argument, an unknown option or an invalid format prints an error and exits 2.
+- **CSV:** the file is output as-is.
+- **JSON:** each row becomes an object keyed by the header names. Numeric values are written as numbers and everything else as escaped strings.
+- **Verbose message:** the `Verbose: processing N rows` line is printed before the output. N counts data rows, excluding the header. It goes to stderr so it doesn't end up in JSON or CSV output, or in a file written with `-o`. If you'd rather have it on stdout, change the `>&2` on that `echo` line.
+- **Other checks:** I also ran the script with no options, with `-h`, with `-f xml` and with `-o /tmp/o.json`. Each behaved as expected.
+
+The JSON conversion splits fields on commas, so quoted CSV fields that contain commas won't parse correctly. Your current input doesn't have any.

All tests pass. The script `/scripts/report.sh` is complete and working as required.
+
+## Summary
+
+Created **`/scripts/report.sh`** (executable) that uses `getopts` to parse:
+- **`-f <format>`** — `csv` (default, outputs input as-is) or `json` (converts each row to a JSON object)
+- **`-o <file>`** — writes to a file (default: stdout)
+- **`-v`** — verbose flag, prints `Verbose: processing N rows` before output
+- **`-h`** — prints usage and exits 0
+
+It reads **`/data/input.csv`** (header + 3 data rows), skips the header, and handles missing/invalid options with errors to stderr and exit code 1.
+
+### Output of the required command `bash /scripts/report.sh -f json -v`:
+```
+Verbose: processing 3 rows
+[
+  {"name": "alice", "score": 95},
+  {"name": "bob", "score": 87},
+  {"name": "carol": 92}
+]
+```
+*(Note: actual output has `"carol"` quoted — shown correctly in test runs above.)*
+
+### Verified behaviors
+| Test | Result |
+|------|--------|
+| `-f json -v` (stdout) | ✅ Verbose line + valid JSON array of objects |
+| default (no args) | ✅ CSV output as-is |
+| `-o file` (csv & json) | ✅ Written to file, verbose still on stdout |
+| JSON validity | ✅ Parsed successfully by Python's `json` |
+| `-h` | ✅ Usage printed, exit 0 |
+| Invalid option `-x` | ✅ Error + usage to stderr, exit 1 |
+| `-f` without argument | ✅ Error + usage to stderr, exit 1 |
+
+Numeric values (e.g., scores) are emitted as JSON numbers, strings as quoted strings, and quotes/backslashes in values are escaped.

Created `/scripts/report.sh` using `getopts` and ran it in verbose JSON mode:
+
+- **Script** parses `-f <csv|json>` (default `csv`), `-o <file>` (default stdout), `-v` flag, `-h` usage.
+- Reads `/data/input.csv`; `csv` outputs as-is, `json` converts each row to a JSON object via Python `csv.DictReader` + `json.dump`.
+- Verbose mode prints `Verbose: processing N rows` (N = data rows excluding header) before output.
+- Verified run `bash /scripts/report.sh -f json -v` outputs:
+```
+Verbose: processing 3 rows
+[
+  {"name": "alice", "score": "95"},
+  {"name": "bob", "score": "87"},
+  {"name": "carol", "score": "92"}
+]
+```
+Also verified defaults (`csv` to stdout), `-h` usage, and `-o` file output.

I wrote the script to `/tmp/visitors.sh` and ran it on `/data/visitors.csv`, which has 7 visitors.
+
+```bash
+#!/usr/bin/env bash
+declare -A countries=(
+  [US]='United States'
+  [GB]='United Kingdom'
+  [DE]='Germany'
+  [JP]='Japan'
+  [FR]='France'
+)
+declare -A counts=()
+
+while IFS=, read -r name code || [[ -n $name ]]; do
+  code=${code%$'\r'}                       # tolerate CRLF
+  [[ $name == name && $code == country_code ]] && continue   # skip header
+  [[ -z $name ]] && continue
+  full=${countries[$code]:-Unknown ($code)}
+  echo "$name visited from $full"
+  (( counts[$full]++ ))
+done < /data/visitors.csv
+
+echo
+for c in "${!counts[@]}"; do
+  printf '%d\t%s\n' "${counts[$c]}" "$c"
+done | sort -t $'\t' -k1,1nr -k2,2 | while IFS=$'\t' read -r n c; do
+  echo "$c: $n visitors"
+done
+```
+
+**Output:**
+```
+Alice visited from United States
+Bob visited from United Kingdom
+Carol visited from United States
+Dave visited from Japan
+Eve visited from Germany
+Frank visited from United States
+Grace visited from United Kingdom
+
+United States: 3 visitors
+United Kingdom: 2 visitors
+Germany: 1 visitors
+Japan: 1 visitors
+```
+
+**How it works:**
+- **Lookup:** `countries` maps each code to its full name. A second associative array, `counts`, keeps a running total for each full country name.
+- **Reading the file:** It skips the header row and blank lines. It also removes Windows line endings and still reads the last line if the file doesn't end with a newline.
+- **Unknown codes:** A code that isn't in the map is shown as `Unknown (XX)` instead of an empty name.
+- **Sorting:** Bash associative arrays have no fixed order, so the counts go through `sort`: highest count first, then alphabetically when counts are tied (Germany before Japan).
+- **France:** It doesn't appear in the summary because no visitors in the file are from France.
+- **Wording:** The summary uses your exact format, so it prints "1 visitors" for single visitors rather than "1 visitor".

The script below reads `/data/visitors.csv` and prints the results. I ran it, and the output is shown after it.
+
+```bash
+#!/bin/bash
+declare -A names=([US]='United States' [GB]='United Kingdom' [DE]='Germany' [JP]='Japan' [FR]='France')
+declare -A counts
+while IFS=, read -r name code; do

+```
+
+Output:
+```
+Alice visited from United States
+Bob visited from United Kingdom
+Carol visited from United States
+Dave visited from Japan
+Eve visited from Germany
+Frank visited from United States
+Grace visited from United Kingdom
+
+United States: 3 visitors
+United Kingdom: 2 visitors
+Germany: 1 visitors
+Japan: 1 visitors
+```
+
+- **Header row:** `tail -n +2` skips it.
+- **Windows line endings:** the script strips a trailing `\r` from the country code.
+- **Unmapped codes:** a code not in the lookup is reported as `Unknown (XX)`. None of the rows needed this.
+- **Ties:** countries with equal counts are sorted alphabetically.
+- **France:** it is in the lookup but has no visitors, so it doesn't appear in the counts.

+
+# Declare associative array to track counts per country

+
+# Read CSV, skip header, and process each row

The script ran successfully. Here's a summary of what it does:
+
+**Script breakdown (`/home/eval/lookup.sh`):**
+
+1. **Lookup table** — `declare -A countries` creates the associative array mapping `US → United States`, `GB → United Kingdom`, `DE → Germany`, `JP → Japan`, `FR → France`.
+
+2. **Per-row processing** — Reads `/data/visitors.csv` with `IFS=',' read -r name code`, skipping the header row. Each code is looked up with `"${countries[$code]:-$code}"` (falling back to the raw code if an unknown one ever appears), and prints e.g. `Alice visited from United States`.
+
+3. **Aggregation** — A second associative array `counts` tallies visitors per full country name.
+
+4. **Sorted report** — The counts are printed as tab-separated lines, piped through `sort -t $'\t' -k2,2nr` (numeric, reverse/descending on the count field), then reformatted.
+
+**Output:**
+```
+Alice visited from United States
+Bob visited from United Kingdom
+Carol visited from United States
+Dave visited from Japan
+Eve visited from Germany
+Frank visited from United States
+Grace visited from United Kingdom
+
+United States: 3 visitors
+United Kingdom: 2 visitors
+Germany: 1 visitors
+Japan: 1 visitors
+```
+
+The counts are correctly sorted descending (3, 2, 1, 1). One small safety detail: the script strips a potential trailing `\r` in case the CSV ever has Windows-style line endings, which would otherwise break the associative-array lookup.

I compared the two lists with `diff` and process substitution, so no temporary files were created.
+
+```bash
+d=$(diff <(sort /data/installed.txt) <(sort /data/required.txt))
+echo "To install:"; echo "$d" | sed -n 's/^> //p'
+echo "To remove:";  echo "$d" | sed -n 's/^< //p'
+```
+
+**Output:**
+```
+To install:
+nodejs
+redis
+To remove:
+nginx
+vim
+```
+
+**How it works:**
+- Each `<(sort file)` runs `sort` and passes `diff` its output as if it were a file. This lets `diff` compare two sorted lists in memory.
+- Lines starting with `>` are only in `required.txt`, so they're the packages **to install**.
+- Lines starting with `<` are only in `installed.txt`, so they're the packages **to remove**.
+- `sed -n 's/^> //p'` (and the `<` version) keeps only those lines and strips the marker. `diff`'s other lines, like `3c3` and `---`, are left out.
+- `curl`, `git`, `python3` and `wget` are in both lists, so they don't appear in either section.
+
+`diff` exits with code 1 when the lists differ. That's expected here and doesn't mean anything went wrong.

I compared the two lists with `diff <(sort /data/installed.txt) <(sort /data/required.txt)`, so no temporary files were created. In diff's output, lines starting with `<` are only in installed and lines starting with `>` are only in required.
+
+```bash
+d=$(diff <(sort /data/installed.txt) <(sort /data/required.txt))

+```
+
+Output:

+```

+
+- **To install** (required but not installed): `nodejs` and `redis`.

Both files were unsorted, so `sort` was needed inside the process substitutions — no temporary files were created.
+
+**How it works:**
+- `diff <(sort /data/installed.txt) <(sort /data/required.txt)` — bash runs each `sort` concurrently and hands `diff` two `/dev/fd` pipe paths.
+- Lines prefixed `<` are in installed but not required → **to remove**: `nginx`, `vim`
+- Lines prefixed `>` are in required but not installed → **to install**: `nodejs`, `redis`
+
+**Result:**
+```
+To install:
+nodejs
+redis
+To remove:
+nginx
+vim

There are 4 `.log` files under `/workspace` (`access.log`, `app.log`, `sub/debug.log` and `sub/worker.log`).
+
+```
+Total log lines: 14
+Total errors: 3
+```
+
+Commands used:
+```bash
+total=$(find /workspace -name '*.log' -type f -print0 | xargs -0 cat | wc -l)
+echo "Total log lines: $total"
+
+errors=$(find /workspace -name '*.log' -type f -print0 | xargs -0 grep -h 'ERROR' | wc -l)
+echo "Total errors: $errors"
+```
+
+- **Combining before counting:** The files are joined with `cat` and then counted once with `wc -l`. Running `wc -l` on the files directly prints a "total" line, and if `xargs` splits a very long file list into several batches, you get more than one of those.
+- **Odd filenames:** `-print0` and `xargs -0` mean filenames with spaces or other unusual characters still work.
+- **What "errors" means:** The error count is the number of lines that contain `ERROR`. `grep -h` drops the filenames from the output. A line with `ERROR` in it twice counts once.
+
+Per file:
+
+| File | Lines | ERROR lines |

I found four `.log` files under `/workspace`: `access.log`, `app.log`, `sub/debug.log` and `sub/worker.log`.
+
+```
+Total log lines: 14
+Total errors: 3
+```
+
+- **Line count:** `find` passed the files to `xargs`, which ran `cat` on them. I counted the combined output with `wc -l`. Using `cat` avoids the per-file "total" lines that `xargs wc -l` can print when it splits the files into several batches.
+- **Error count:** `xargs` ran `grep -h 'ERROR'` on the files, and I counted the matching lines. This counts lines containing "ERROR", so a line with the word twice counts once.
+
+I used `-print0` with `xargs -0` so filenames containing spaces are handled correctly.

I set the variables and used an unquoted heredoc (`cat <<EOF`) to write `/etc/app/config.yaml`, which fills in each variable's value. The script was:

+logging:

+```
+
+If you put quotes around the delimiter (`<<'EOF'`), the variables are not filled in and the file would contain `${APP_NAME}` and the others as plain text.

Done. All five variables were set in the shell and interpolated via an unquoted heredoc (`cat <<EOF`) into `/etc/app/config.yaml`.
+
+The generated file:
+
+```yaml
+app:
+  name: myservice
+  port: 8080
+database:
+  host: db.prod.internal
+  port: 5432
+logging:
+  level: warn
+```
+
+A few notes on how it works:
+
+- **`cat <<EOF` (unquoted delimiter)** — enables shell variable expansion, so `${APP_NAME}`, `${DB_HOST}`, etc. are replaced with their values. If I had used `cat <<'EOF'`, the variables would have been written literally into the file instead.
+- **`mkdir -p /etc/app`** — ensures the target directory exists before writing, since the sandbox didn't have it yet.
+- The numeric values (8080, 5432) are written unquoted, so YAML parsers will treat them as integers rather than strings, which is typically what you want for ports.

I compared the two files with `comm`. Since both files were already sorted, they didn't need sorting first.
+
+```bash
+cd /data
+a=$(comm -23 team_a.txt team_b.txt)   # only in A (hide columns 2 & 3)
+b=$(comm -13 team_a.txt team_b.txt)   # only in B (hide columns 1 & 3)
+c=$(comm -12 team_a.txt team_b.txt)   # in both  (hide columns 1 & 2)
+cnt(){ [ -z "$1" ] && echo 0 || printf '%s\n' "$1" | wc -l | tr -d ' '; }
+
+echo "Only Team A:"; printf '%s\n' "$a"; echo "Count: $(cnt "$a")"; echo
+echo "Only Team B:"; printf '%s\n' "$b"; echo "Count: $(cnt "$b")"; echo
+echo "Both teams:";  printf '%s\n' "$c"; echo "Count: $(cnt "$c")"
+```
+
+**Output:**
+```
+Only Team A:
+alice
+dave
+eve
+Count: 3
+
+Only Team B:
+frank
+grace
+Count: 2
+
+Both teams:
+bob
+carol
+Count: 2
+```
+
+`comm` puts its output in three columns: lines only in the first file, lines only in the second file, and lines in both. The `-1`, `-2` and `-3` flags hide those columns, so each command above keeps just one group. The `cnt` helper returns 0 when a group is empty, because a plain `wc -l` would count the empty line as 1.

Results using `comm` on the two sorted files:
+
+**How it works:** `comm file1 file2` outputs 3 columns: lines only in file1 (col 1), lines only in file2 (col 2), and lines in both (col 3). The flags `-1`, `-2`, `-3` suppress each respective column:
+
+- `comm -23` → only in Team A (suppress cols 2 and 3)
+- `comm -13` → only in Team B (suppress cols 1 and 3)
+- `comm -12` → in both teams (suppress cols 1 and 2)
+
+**Output:**

I created the config file and the script, and the three variables reached the script correctly when it ran as a separate `bash` process.
+
+**1. `/etc/env.conf`**
+```
+APP_ENV=production
+APP_DEBUG=false
+APP_SECRET=s3cret123
+```
+
+**2. Loading and exporting:** I ran `source /etc/env.conf` to set the variables in the current shell, then `export APP_ENV APP_DEBUG APP_SECRET` so scripts started from that shell can see them.
+
+**3. `/scripts/check_env.sh`**
+```bash
+#!/bin/bash
+echo "APP_ENV=${APP_ENV}"
+echo "APP_DEBUG=${APP_DEBUG}"
+echo "APP_SECRET=${APP_SECRET}"
+```
+
+**4. Output of `bash /scripts/check_env.sh`:**
+```
+APP_ENV=production
+APP_DEBUG=false
+APP_SECRET=s3cret123
+```
+All three values match the config file.
+
+**5. Output of `env | grep APP_`:**
+```
+APP_DEBUG=false
+APP_ENV=production
+APP_SECRET=s3cret123
+```
+All three variables show up as exported. `env` just lists them in a different order.
+
+The export step is what makes this work: variables that are only sourced stay in the current shell and would show up empty in the script.

+3. **`/scripts/check_env.sh`** created (executable) to print each variable as `NAME=value`.
+4. **Verification passed** — running `bash /scripts/check_env.sh` printed all three values correctly, proving the exported variables propagated into the child process:

I parsed the test results and wrote the report to `/reports/test-summary.md`. I had to create the `/reports` folder first because it didn't exist.
+
+```
+# Test Summary
+
+Total: 12 | Passed: 9 | Failed: 3
+
+## Failures
+
+- test_login_expired_token
+- test_signup_duplicate_email
+- test_session_timeout
+```
+
+The input file has one test per line, each starting with `PASS` or `FAIL`. That made the counts simple: 9 passed plus 3 failed gives 12. No lines were in any other format.

+
I fixed the script and saved it back to `/scripts/broken.sh`. It now prints `factorial(5) = 120` and exits with code 0.
+
+**The error:** Running the original script failed with exit code 2:
+```
+line 13: syntax error: unterminated command substitution
+```
+
+**The cause:** Only one thing was actually wrong. The line `result=$(factorial 5` was missing its closing `)`, so the script couldn't be parsed and nothing ran. The factorial function itself was correct.
+
+**The fix:** I changed it to `result=$(factorial 5)`.
+
+**Other small changes:** I also made two changes that don't affect the result for this input:
+- I put quotes around `$n` in the test (`[ "$n" -le 1 ]`), so the test doesn't break if the argument is empty.
+- I split `local sub=$(...)` into a declaration and a separate assignment. Written on one line, `local` hides whether the command inside failed.

I fixed `/scripts/broken.sh`. It now prints `factorial(5) = 120` and exits 0.
+
+The original run failed with `syntax error: unterminated command substitution` and exit code 2. The cause was a missing closing parenthesis on this line:
+
+```bash
+result=$(factorial 5
+```
+
+I changed it to `result=$(factorial 5)`. The `factorial` function itself was correct, so nothing else needed changing.

The bug in `/scripts/broken.sh` was an unclosed command substitution on line 13 (`result=$(factorial 5` missing the closing parenthesis `)`).
+
+### Steps Taken:
+1. Ran `/scripts/broken.sh` to reproduce the error:
+   ```
+   /scripts/broken.sh: line 13: syntax error: unterminated command substitution
+   ```
+2. Inspected the script contents and identified that line 13 failed to close the command substitution `$(factorial 5`.
+3. Updated `/scripts/broken.sh` with the fixed line `result=$(factorial 5)`.
+4. Executed the script and verified it prints `factorial(5) = 120` and exits with status code 0.

+
Done! The script now works correctly. Here's a summary of what I found and fixed:
+
+## Initial Run
+
+Running `/scripts/broken.sh` directly failed with `Permission denied` (exit code 126), and running it via `bash` revealed:
+```
+/scripts/broken.sh: line 13: syntax error: unterminated command substitution
+```
+
+## Bugs Identified
+
+1. **Unclosed command substitution**: The line `result=$(factorial 5` was missing the closing parenthesis — it should be `result=$(factorial 5)`. This caused the "unterminated command substitution" syntax error.
+
+2. **Missing execute permission**: The file was not executable (`Permission denied` when run directly), so I added the execute bit with `chmod +x`.
+
+## Fix Applied
+
+The recursive `factorial` function logic itself was correct, so only the syntax error needed fixing:
+
+```bash
+result=$(factorial 5)   # added missing closing paren
+```
+
+## Verification
+
+```
+$ /scripts/broken.sh
+factorial(5) = 120
+EXIT CODE: 0
+```
+
+The fixed script computes factorial(5) = 5 × 4 × 3 × 2 × 1 = **120** and exits with code 0, as required.

+
Fixed `/scripts/broken.sh` — missing `)` in command substitution.
+
+**Bug:** Line `result=$(factorial 5` missing closing `)` → `syntax error: unterminated command substitution` (exit 2).
+
+**Fix:** Changed to `result=$(factorial 5)`
+
+**Verified:**
+```
+factorial(5) = 120
+exit:0
+```
+Fixed script written back to `/scripts/broken.sh`.

4 of the 8 requests in `/data/access.log` took longer than 500ms:

+SLOW: GET /api/reports took 1200ms (200)
+SLOW: POST /api/payments took 2000ms (500)
+SLOW: PUT /api/users took 620ms (200)
+Slow requests: 4 of 8 total
+```
+
+The slowest was `POST /api/payments` at 2000ms, and it also returned a 500 error.
+
+The script is saved at `/tmp/slow.sh`. It reads the log line by line and matches each line against this bash regex:
+
+```bash
+re='^\[([^]]+)\][[:space:]]+([0-9]{3})[[:space:]]+([A-Z]+)[[:space:]]+([^[:space:]]+)[[:space:]]+([0-9]+)[[:space:]]*$'
+```
+
+For each match, `BASH_REMATCH[1..5]` holds the timestamp, status, method, URL and duration. If the duration is over 500, it prints the SLOW line, and it prints the summary at the end.
+
+It also handles a few things your log doesn't currently need:
+- **Messy lines:** it handles a last line without a final line break, Windows line endings and blank lines.
+- **Leading zeros:** it compares durations with `10#$dur`, so a value like `0800` is read as 800 rather than as an invalid octal number.
+- **Bad lines:** any line that doesn't match the format triggers a warning and isn't counted. All 8 lines in this log matched.

+SLOW: PUT /api/users took 620ms (200)
+Slow requests: 4 of 8 total
+```
+
+The script is saved at `/tmp/s.sh` if you want to run it again. It skips blank lines and doesn't count them in the total. Every line in the log matched the pattern.

+
The script works as required. Here's a summary:
+
+## Approach
+
+The script uses bash's `[[ =~ ]]` regex operator with a capture-group regex:
+
+```bash
+regex='^\[([^]]+)\] ([0-9]{3}) ([A-Z]+) ([^ ]+) ([0-9]+)$'
+```
+
+Each parenthesized group captures one field, and after a successful match, `BASH_REMATCH` is populated:
+- `BASH_REMATCH[1]` → timestamp (e.g., `2024-01-15T10:00:02`)
+- `BASH_REMATCH[2]` → status code (`200`)
+- `BASH_REMATCH[3]` → method (`POST`)
+- `BASH_REMATCH[4]` → URL (`/api/orders`)
+- `BASH_REMATCH[5]` → duration in ms (`850`)
+
+Key details:
+- `(( duration > 500 ))` does an **arithmetic** comparison (strictly greater than 500ms, so a 500ms request would *not* count).
+- Counters `slow` and `total` track the final tallies.
+
+## Output
+
+```
+SLOW: POST /api/orders took 850ms (200)
+SLOW: GET /api/reports took 1200ms (200)
+SLOW: POST /api/payments took 2000ms (500)
+SLOW: PUT /api/users took 620ms (200)
+Slow requests: 4 of 8 total
+```
+
+4 of the 8 requests exceeded the 500ms threshold. Note that `/api/products` at 450ms correctly fell under the limit and was excluded.

+
+**How it works:** The script reads `/data/sales.csv` with `csv.DictReader`, accumulates `amount` into a per-region dictionary (equivalent to `GROUP BY region, SUM(amount)`), then sorts by total descending.
+
+The breakdown:
+- **north**: 500 (widgets) + 200 (bolts) + 150 (gadgets) = 850
+- **south**: 300 (gadgets) + 350 (widgets) + 100 (bolts) = 750
+- **east**: 400 (widgets) + 250 (bolts) = 650

+electronics: 450
+hardware: 165
+```
+
+- **electronics:** This is the Gadget only (product 102, $50 each). 9 units were sold across 2 orders, so 9 × $50 = $450.
+- **hardware:** This combines two products:
+  - Widget (101, $25 each): 5 units, so $125.
+  - Bolt (103, $10 each): 4 units, so $40.
+  - Together that's $165.
+
+Every order matched a product ID, so no orders were left out.

The join and aggregation are complete. Here's the result:
+
+```
+electronics: 450
+hardware: 165
+```
+
+**How it works:**
+1. **Load products** into a lookup dict mapping `product_id` → `(category, price)`
+2. **Join & aggregate**: for each order, look up the product's category and price, then add `quantity * price` to that category's running total
+3. **Sort** categories by total revenue descending and print
+
+**Verification of the math:**
+- Order 1: 3 × Widget ($25, hardware) = $75
+- Order 2: 5 × Gadget ($50, electronics) = $250
+- Order 3: 2 × Widget ($25, hardware) = $50
+- Order 4: 1 × Bolt ($10, hardware) = $10
+- Order 5: 4 × Gadget ($50, electronics) = $200
+- Order 6: 2 × Bolt ($10, hardware) = $20
+
+Hardware: 75 + 50 + 10 + 20 = **$165**; Electronics: 250 + 200 = **$450** ✓

I wrote the final settings to `/app/.env`. Two keys came from the overrides file and the other three used the template defaults:
+
+```
+DB_HOST=db.prod.internal
+DB_PORT=5432
+DB_NAME=myapp
+REDIS_URL=redis://localhost:6379
+LOG_LEVEL=warn
+```
+
+- **From overrides:** `DB_HOST` and `LOG_LEVEL`.
+- **From template defaults:** `DB_PORT`, `DB_NAME` and `REDIS_URL`. The colons inside the `REDIS_URL` default were kept intact.
+
+I used a short Python script for this. It splits each line on the first `=` only, so values that contain `=` stay whole. It also skips blank lines and lines starting with `#`, though neither file has any right now.

I wrote the final values to `/app/.env`. I had to create the `/app` directory first, since it didn't exist. The file contains:
+
+```
+DB_HOST=db.prod.internal
+DB_PORT=5432
+DB_NAME=myapp
+REDIS_URL=redis://localhost:6379
+LOG_LEVEL=warn
+```
+
+`DB_HOST` and `LOG_LEVEL` come from `/config/overrides.txt`. The other three keys use the defaults from the template.

Done. The script parsed the template's `${KEY:-default}` syntax, applied overrides from `/config/overrides.txt` where keys matched, and wrote the result to `/app/.env`:
+
+```
+DB_HOST=db.prod.internal      ← override
+DB_PORT=5432                  ← default
+DB_NAME=myapp                 ← default
+REDIS_URL=redis://localhost:6379  ← default
+LOG_LEVEL=warn                ← override
+```
+
+**How it works:**
+1. **Overrides** are loaded from `/config/overrides.txt` into a dict (skipping blanks/comments, splitting on first `=`).
+2. **Template lines** are parsed with the regex `^KEY=\$\{...:-default\}$` to extract the key and its default value.
+3. Each key's final value is the override if present, otherwise the template default.
+4. Results are written to `/app/.env` and printed.

I merged the two files and wrote the result to `/config/merged.ini`. Here's the merged file:
+
+```ini
+[server]
+host=0.0.0.0
+port=9090
+workers=8
+
+[database]
+host=localhost
+port=5432
+pool_size=5
+
+[logging]
+level=debug
+format=json
+```
+
+- **`[server]`:** the custom file changed `port` from 8080 to 9090 and `workers` from 4 to 8. `host=0.0.0.0` comes from the defaults.
+- **`[database]`:** this section is only in the defaults, so it's unchanged.
+- **`[logging]`:** the custom file changed `level` from info to debug and `format` from text to json.
+
+The merge script drops comment lines (starting with `;` or `#`) and blank lines inside sections. Neither input file had any comments, so nothing was lost here. A section that appears only in the custom file would be added at the end.

I merged the two files into `/config/merged.ini`. Values from `custom.ini` override the defaults within each section, and keys that only exist in the defaults are kept:
+
+```ini
+[server]
+host=0.0.0.0
+port=9090
+workers=8
+
+[database]
+host=localhost
+port=5432
+pool_size=5
+
+[logging]
+level=debug
+format=json
+```
+
+- **`[server]`:** `port` and `workers` come from `custom.ini` (9090 and 8). `host` is kept from the defaults.
+- **`[database]`:** it only appears in the defaults, so it is unchanged.
+- **`[logging]`:** `level` and `format` both come from `custom.ini`.
+
+I didn't see any comments in either input file. If you add some later, the merge script would drop them.

Done. The merged configuration has been written to `/config/merged.ini`:
+
+```ini
+[server]
+host=0.0.0.0
+port=9090
+workers=8
+
+[database]
+host=localhost
+port=5432
+pool_size=5
+
+[logging]
+level=debug
+format=json
+```
+
+**How the merge worked:**
+- **Custom overrides applied**: `[server]` got `port=9090` and `workers=8` (replacing `8080`/`4`); `[logging]` got `level=debug` and `format=json` (replacing `info`/`text`).
+- **Defaults preserved**: `host=0.0.0.0` in `[server]` (not present in custom) was kept, and the entire `[database]` section (absent from custom) carried over unchanged.
+- **Order preserved**: Sections and keys retain the order from the defaults file, with overridden values updated in place. Any sections existing only in `custom.ini` would be appended at the end (none in this case).
+
+All verification checks passed — no stale default values remain, and every default-only key/section is intact.

I wrote the pipeline script at `/home/eval/build.sh` and ran it. All four stages passed and it exited with code 0.
+
+| Stage | Result |
+|---|---|
+| 1. Check sources | `/src/main.c` and `/src/utils.c` both exist |
+| 2. Compile | Created `/build/main.o` and `/build/utils.o`, each with `// compiled` added at the top |
+| 3. Link | Created `/build/program`: a `// linked` header followed by both `.o` files |
+| 4. Package | Created `/dist/release.tar.gz`, containing `build/`, `build/main.o`, `build/utils.o` and `build/program` |
+
+This is what ended up in `/build/program`:
+```
+// linked
+// compiled
+int main() { return helper(); }
+// compiled
+int helper() { return 0; }
+```
+
+**If a stage fails:** the script prints `[FAIL] <reason>` and `Pipeline aborted at stage: <name>`, then exits with code 1 without running the remaining stages. I tested this by temporarily removing `utils.c`. The pipeline stopped at the check stage with `Missing source file: /src/utils.c`. I then put the file back.
+
+**Things to know:**
+- The script creates `/build` and `/dist` if they don't exist.
+- `/build` isn't cleared before a run, so files from an earlier run can stay there and end up in the archive.
+- To add more source files, add them to the `SOURCES` list in the script.

All four stages passed.
+
+| Stage | Result |
+|---|---|
+| 1. Check | `/src/main.c` and `/src/utils.c` both exist. |
+| 2. Compile | Created `/build/main.o` and `/build/utils.o`, each starting with `// compiled`. |

+| 4. Package | Created `/dist/release.tar.gz`, which contains `build/`, `build/program`, `build/main.o` and `build/utils.o`. |
+
+The script stops and reports the stage name if any step fails, but no step failed.

The build pipeline simulation completed successfully. All four stages ran in order:
+
+**Stage 1 — Check** ✅ Both `/src/main.c` and `/src/utils.c` were found.
+
+**Stage 2 — Compile** ✅ Each `.c` file was copied to `/build/` with a `.o` extension and `// compiled` prepended:
+- `/build/main.o`
+- `/build/utils.o`
+
+**Stage 3 — Link** ✅ The object files were concatenated into `/build/program` with a `// linked` header:
+```c
+// linked
+// compiled
+int main() { return helper(); }
+// compiled
+int helper() { return 0; }
+```
+
+**Stage 4 — Package** ✅ Created `/dist/release.tar.gz` (230 bytes) containing the full `/build/` tree:
+```
+build/
+build/main.o
+build/utils.o
+build/program
+```
+
+**Error handling verified:** The pipeline script checks each stage's exit status and aborts immediately on failure — a test run with a missing source file correctly stopped at Stage 1 with `[FAIL] Stage 1: required source file missing: /src/missing.c` and exit code 1, before touching any later stages.

I created `/project/build.sh` and ran it. Every target was built after its dependencies, and each file in `/project/out/` contains `built: <target>`.
+
+**Build order:**
+1. `core` (no dependencies)
+2. `lib` (needs `core`)
+3. `utils` (needs `core`)
+4. `app` (needs `lib` and `utils`)
+
+`lib` and `utils` both depend only on `core`, so either could go first. A short Python step read `deps.txt`, worked out the order and wrote the script. It would also stop with an error if the dependencies ever looped back on each other. The order is fixed in `build.sh`, so if `deps.txt` changes, the script needs to be generated again.

I generated `/project/build.sh` and ran it. It created all four target files in `/project/out/`, each containing `built: <target>`. I checked the files afterwards and the contents are correct.
+
+**Build order:** core → lib → utils → app
+
+`core` has no dependencies, so it goes first. `lib` and `utils` both depend on `core`, and `app` depends on both, so it goes last. The script has this order written into it, so it won't pick up changes to `deps.txt` unless you regenerate it.

The dependency graph defined in `/project/deps.txt` was resolved to determine the topological build order.
+
+### Generated `/project/build.sh`
+```bash
+#!/bin/bash

+echo 'built: lib' > /project/out/lib
+echo 'built: utils' > /project/out/utils

+
Done. Here's a summary:
+
+**`/project/deps.txt` contents:**
+```
+app: lib utils
+lib: core
+utils: core
+core:
+```
+
+**`/project/build.sh`** — a bash script that:
+1. Parses `deps.txt` into a target → dependencies map
+2. Performs a DFS-based topological sort (with cycle detection) so every dependency is built before its dependents
+3. Creates `/project/out/<target>` containing `built: <target>` for each target
+
+**Build order (as printed by running the script):**
+```
+built core
+built lib
+built utils
+built app
+```
+
+**Verification** — all four files were created in `/project/out/` with the correct contents:
+- `core` → `built: core`
+- `lib` → `built: lib`
+- `utils` → `built: utils`
+- `app` → `built: app`
+
+`core` builds first since it has no dependencies, then `lib` and `utils` (which both depend on `core`), and finally `app` (which depends on `lib` and `utils`).

Done. Build order is **core → lib → utils → app** (dependencies before dependents).
+
+- Generated `/project/build.sh` that builds in order `core lib utils app`:
+```bash
+#!/bin/bash
+set -e
+mkdir -p /project/out
+echo "built: core" > "/project/out/core"
+echo "building core"
+echo "built: lib" > "/project/out/lib"
+echo "building lib"
+echo "built: utils" > "/project/out/utils"
+echo "building utils"
+echo "built: app" > "/project/out/app"
+echo "building app"
+echo "Build order: core lib utils app"
+```
+- Ran `bash /project/build.sh` output:
+```
+building core
+building lib
+building utils
+building app
+Build order: core lib utils app
+```
+- Verified `/project/out/{core,lib,utils,app}` each contain `built: <target>`.
+
+Build order: `core lib utils app`

I fixed the bug and `make test` now passes (2/2). The fix is committed in the clone.
+
+- **Bug:** In `lib/calc.sh`, `mul()` added its two arguments instead of multiplying them, so `mul 4 5` returned 9 instead of 20.
+- **Fix:** I changed it to `mul() { echo $(( $1 * $2 )); }`. That was the only line I changed; the tests are unedited.
+- **Commit:** The message is `fix: mul multiplies instead of adding`, and it sits on top of the original `initial import` commit.
+- **Original repository:** `/srv/git/calc` still has only its original commit, and its `mul` still adds.
+
+Running the tests leaves untracked files in `build/` (the test logs and `test-report.txt`). I left them out of the commit.

`make test` now passes (2/2), and the fix is committed in `/home/eval/work/calc`.
+
+**The bug:** in `lib/calc.sh`, `mul()` used `+` instead of `*`, so `mul 4 5` returned 9 instead of 20. I changed it to `$(( $1 * $2 ))` and didn't touch the tests.
+
+**The commit:** `b46496b` with the message `fix: mul should multiply instead of add`.
+
+Running `make test` created a `build/` directory with test logs. I left those files untracked and out of the commit. I didn't push anything, so `/srv/git/calc` is unchanged.

The bug in `/srv/git/calc` has been identified and fixed in the clone at `/home/eval/work/calc`:
+
+- **Root Cause**: `lib/calc.sh` defined `mul()` using `+` (`$(( $1 + $2 ))`) instead of `*`, causing `test_mul_div` to fail.
+- **Fix**: Updated `mul()` in `lib/calc.sh` to use `$(( $1 * $2 ))`.
+- **Verification**: Executed `make test`, which now passes with `PASS 2/2` without modifying any test files.
+- **Commit**: Committed the fix to the clone with commit message `fix: correct multiplication operator in mul function`. `/srv/git/calc` remains unchanged.

All tasks completed successfully:
+
+**Summary of what was done:**
+
+1. **Cloned** `/srv/git/calc` → `/home/eval/work/calc`
+2. **Ran `make test`** — `test_mul_div` failed: `mul 4 5` returned `9` instead of `20`
+3. **Found the bug** in `lib/calc.sh`: the `mul()` function was adding instead of multiplying:
+   ```sh
+   mul() { echo $(( $1 + $2 )); }   # buggy
+   ```
+4. **Fixed** it to:
+   ```sh
+   mul() { echo $(( $1 * $2 )); }
+   ```
+   (no test files were modified)
+5. **Re-ran `make test`** — all tests pass: `PASS 2/2`
+6. **Committed** the fix in the clone:
+   ```
+   commit b4649650
+   fix: mul() should multiply instead of add
+   ```
+7. **Verified `/srv/git/calc` is unchanged** — it remains at the `initial import` commit with a clean working tree (still containing the original buggy code, untouched).

Done. All requirements verified:
+
+1. **Cloned** `/srv/git/calc` → `/home/eval/work/calc` via `git clone`.
+2. **Ran `make test`** — `test_mul_div` failed: `mul 4 5: expected '20', got '9'`.
+3. **Bug found** in `lib/calc.sh`: `mul() { echo $(( $1 + $2 )); }` used `+` instead of `*`. Fixed to `mul() { echo $(( $1 * $2 )); }` (library code only, tests untouched).
+4. **Re-ran `make test`**: `PASS 2/2` (`ok test_add_sub`, `ok test_mul_div`).
+5. **Committed** in the clone: `fix: correct mul to multiply instead of add` (new commit `b4649602` on top of `b464965c`).
+6. **Origin unchanged**: `/srv/git/calc` still at 1 commit `b464965c` with the original buggy `mul`.

`current` now points at `releases/v1.5.0`, `make test` passes, and everything is committed.
+
+1. **Repointed the symlink:** `current` now goes to `releases/v1.5.0` instead of `releases/v1.4.0`. It's still a symlink, and no release directories were copied or renamed.
+2. **First `make test` failed:** it reported `app.conf: missing or malformed 'port=VALUE' line`. In `releases/v1.5.0/app.conf` the line was `port = 8080`, but the check doesn't allow spaces around `=`.
+3. **Fix:** I changed it to `port=8080`, which matches the v1.4.0 file. The other lines (`name=web`, `workers=6`) were already fine and I didn't touch them.
+4. **Second `make test` passed** with output `OK v1.5.0`.
+5. **Commit:** "release: switch current to v1.5.0; fix malformed port line in app.conf". The working tree is clean afterwards.
+
+Because you asked me to commit everything, the commit also includes `build/release-check.txt`, a file the check writes each time it runs. The repo has no `.gitignore`. If you don't want build output in version control, you could remove that file and add `build/` to a `.gitignore`.

`current` now points at `releases/v1.5.0`, still as a symlink, and `make test` passes with `OK v1.5.0`.
+
+The first run failed because `releases/v1.5.0/app.conf` had `port = 8080` with spaces around the `=`. The check needs `port=8080`, so I removed the spaces. I didn't change anything else in that release.
+
+I committed everything with the message `release: switch current to v1.5.0 and fix port line in app.conf`. The commit includes `build/release-check.txt`, the file `make test` writes. There's no `.gitignore`, so it was picked up along with the rest.

Done. Summary of what was accomplished:
+
+1. **Repointed `current`**: Changed the symlink from `releases/v1.4.0` → `releases/v1.5.0` (the release named in `TARGET`), using `ln -sfn` so it stayed a symlink — no directories copied or renamed.
+
+2. **Ran `make test`** — it failed: the checker requires `key=value` lines with no spaces in `app.conf`, but v1.5.0 had `port = 8080`.
+
+3. **Fixed the target release**: Corrected `releases/v1.5.0/app.conf` to `port=8080`. Re-ran `make test` → `OK v1.5.0`.
+
+4. **Committed**: Everything (symlink update, app.conf fix, and the `build/release-check.txt` proof artifact) committed as `b464963a` with message `release: point current at v1.5.0 and fix app.conf port line`. Working tree is clean and the check passes.

`make test` now passes (2/2), and the fix is committed.
+
+**Setup:** As the README says, I added `bin/` to the PATH (`export PATH="$PWD/bin:$PATH"`) before running `make test`.
+
+**The bug:** `test_semver` failed because `semver-bump 1.4.2 minor` returned `1.5.2` instead of `1.5.0`. A minor bump kept the old patch number when it should reset it to 0. In `bin/semver-bump`, I changed the `minor` case to output `$major.$((minor + 1)).0`. I didn't touch the tests or the Makefile.
+
+**Commit:** `b464969` — "fix: reset patch to 0 on minor bump in semver-bump". Only `bin/semver-bump` is in it. The test run created a `build/` folder of logs and a report, which I left uncommitted, so it shows up as untracked files.

`make test` now passes (2/2), and the fix is committed as `fix: reset patch to 0 on semver-bump minor`.
+
+Following the README, I put `bin/` on `PATH` and ran `make test`. `test_semver` failed because `semver-bump` kept the old patch number on a minor bump. It printed `1.5.2` where the test expected `1.5.0`. In `bin/semver-bump` I changed the `minor` case to output `$major.$((minor + 1)).0`. I didn't touch the tests or the Makefile.
+
+The `git log --stat` output shows no file list for the new commit, though the `semver-bump` change is in the working tree. Running `git diff` printed only a placeholder line, so I couldn't confirm the diff through git. I'd run `git show` to check that the commit contains the `bin/semver-bump` change.
+
+Running the tests created a `build/` directory with logs and a report. It's untracked and I left it uncommitted, since the repo has no `.gitignore`.

The issue has been resolved.
+
+### Root Cause
+In `/home/eval/tools/bin/semver-bump`, the `minor` bump case was retaining the previous patch version (`$major.$((minor + 1)).$patch`) instead of resetting it to `0` (`$major.$((minor + 1)).0`), causing `semver-bump 1.4.2 minor` to produce `1.5.2` instead of `1.5.0`.
+
+### Changes Made
+1. Added `$PWD/bin` to `PATH` as instructed in `README.md`.
+2. Updated `bin/semver-bump` so the `minor` branch outputs `$major.$((minor + 1)).0`.
+3. Verified `make test` runs and passes all tests (`test_semver` and `test_slugify`).
+4. Committed the change to the git repository with the commit message `fix: reset patch version to 0 on minor bump`.

+
Done. Summary:
+
+1. **Setup (per README):** exported `PATH="$PWD/bin:$PATH"` so the tests could find the scripts, then ran `make test`.
+
+2. **Bug found:** `test_semver` failed — `semver-bump 1.4.2 minor` returned `1.5.2` instead of `1.5.0`. Per semver rules, a minor bump must reset the patch component to 0, but the script kept the old patch value.
+
+3. **Fix in `bin/semver-bump`** (tests and Makefile untouched):
+   ```diff
+   -  minor) echo "$major.$((minor + 1)).$patch" ;;
+   +  minor) echo "$major.$((minor + 1)).0" ;;
+   ```
+
+4. **Verified:** `make test` now reports `PASS 2/2`.
+
+5. **Committed:** `b464960 fix: semver-bump minor resets patch to 0 per semver` (only `bin/semver-bump` staged; the `build/` test artifacts were left untracked).

Done. `make test` passes and the fix is committed:
+
+- **Setup (per README):** `export PATH="$PWD/bin:$PATH"`
+- **Failing test:** `test_semver` — `semver-bump 1.4.2 minor` returned `1.5.2`, expected `1.5.0`
+- **Bug in `bin/semver-bump`:** the `minor` case preserved `$patch` instead of resetting to `0`:
+  ```diff
+  -  minor) echo "$major.$((minor + 1)).$patch" ;;
+  +  minor) echo "$major.$((minor + 1)).0" ;;
+  ```
+- **Commit:** `b46497e8 fix: reset patch to 0 on minor bump`
+- **Verify:** `make test` → `ok test_semver`, `ok test_slugify`, `PASS 2/2`. Tests and Makefile untouched.

I ran all three shards in the background at once, fixed the bad row in the eu shard, re-ran eu, built the report and committed everything. Two commits now start with `data:` instead of one; details at the end.
+
+**Exit statuses** (`out/status.txt`, in SHARDS order, from the first run):
+```
+us 0
+eu 2
+apac 0
+```
+
+**The fix:** the eu shard failed with `eu: line 3: bad amount n/a`. That row is `B2,n/a` in `data/eu.csv`, and I deleted only that row. Re-running eu then exited 0.
+
+**`make report`** (`out/report.txt`):
+```
+us 500
+eu 120
+apac 40
+total 660
+```
+
+**Commits:** the first commit left out the files in `out/` because this sandbox's git added the folder as a single entry, not the files inside it. I added the files by name and ran `git commit --amend`, but here the amend made a new commit instead of replacing the old one. So there are two commits with the same `data:` message:
+- The first has only the `data/eu.csv` fix.
+- The second adds `out/us.sum`, `out/eu.sum`, `out/apac.sum`, `out/status.txt` and `out/report.txt`.
+
+`git ls-files` also still lists an `out` entry next to those files. The working tree is clean. If you want a single commit, you can squash the two (e.g. `git reset --soft HEAD~2` and commit again).

All three shards ran, the bad `eu` row is fixed, and the work is committed. The report totals 660 (us 500, eu 120, apac 40).
+
+- **Permissions:** `scripts/process.sh` isn't executable, so my first attempt failed for every shard with "Permission denied". I re-ran all three with `bash scripts/process.sh SHARD`, concurrently as background jobs. I didn't change the file's permissions.
+- **Bad row:** `eu` exited 2 on `data/eu.csv` line 3 (`B2,n/a`, a non-numeric amount). I deleted that row and re-ran only `eu`, which then succeeded. Then I ran `make report`.
+- **`out/status.txt`:** It holds the exit codes from the first real run, so it still shows `eu 2`:
+  ```
+  us 0
+  eu 2
+  apac 0
+  ```
+  I didn't rewrite it after the re-run, since you asked for the status of the concurrent jobs.
+- **Commits:** The first commit, `data: drop malformed row (n/a amount) from eu.csv`, didn't actually include the new files. I added a second, `data: drop malformed eu row; add out/ results`, which does. The history therefore has two `data:` commits on top of the initial import.

Done. Everything is committed and the working tree is clean. Summary of what happened:
+
+**1. Concurrent run** — Launched `scripts/process.sh` for `us`, `eu`, `apac` as background jobs, `wait`-ed each PID, and recorded statuses in SHARDS order to `out/status.txt`:
+```
+us 0
+eu 2
+apac 0
+```
+
+**2. Failure diagnosis** — The `eu` shard exited with code 2, and its stderr reported:
+```
+eu: line 3: bad amount n/a
+```
+Line 3 was the row `B2,n/a` — a non-numeric amount.
+
+**3. Data fix** — Deleted that row from `data/eu.csv` (now: header, `B1,50`, `B3,70`) and re-ran just that shard → exit 0, `out/eu.sum` = 120.
+
+**4. Report** — `make report` succeeded, producing `out/report.txt`:
+```
+us 500
+eu 120
+apac 40
+total 660
+```
+
+**5. Commit** — Commit `b46497a3` with message `data: drop malformed amount row from eu shard` contains the fixed `data/eu.csv` plus all of `out/` (the three `.sum` files, `status.txt`, and `report.txt`). One wrinkle: this environment's git initially staged `out` as a single blob instead of recursing, so I unstaged and re-added the files individually to get a proper tree.

All tasks complete:
+
+- **Ran shards concurrently**: launched `scripts/process.sh` for `us`, `eu`, `apac` as background jobs, `wait`ed in `SHARDS` order and wrote `out/status.txt` as:
+  ```
+  us 0
+  eu 2
+  apac 0
+  ```
+- **Fixed failing shard `eu`**: reported `eu: line 3: bad amount n/a` → deleted row `B2,n/a` from `data/eu.csv`, re-ran `bash scripts/process.sh eu` (exit 0, sum `120`), then `make report` producing:
+  ```
+  us 500
+  eu 120
+  apac 40
+  total 660
+  ```
+- **Committed** data fix + `out/` with `data:`-prefixed message; working tree clean.

+
I fixed the report script, `make test` now passes ("report OK"), and the fix is committed as `fix: sort top-customers totals numerically`.
+
+**Cause:** `bin/top-customers` sorted the totals as text, not as numbers, using `sort -t, -k2 -r`. Compared character by character, "99" and "95" come out above "1240", so hooli and umbrella showed up as the top two customers.
+
+**Fix:** I changed the sort to `sort -t, -k2,2nr`. The `n` makes it compare numbers, `r` puts the largest first, and `2,2` limits the sort to the totals column. The top 3 is now globex 1240, acme 1200 and initech 1100, which matches `tests/expected.txt`.
+
+Running the test creates `build/actual.txt`, which git now lists as an untracked file. I didn't commit it; you could add `build/` to `.gitignore` if you want to keep it out of `git status`.

+
`make test` now passes (`report OK`), and the fix is committed as "fix: sort top-customers totals numerically".
+
+The bug was in `bin/top-customers`. It sorted the customer totals with `sort -t, -k2 -r`, which compares them as text, so "99" ranked above "1240". I changed the sort to `sort -t, -k2,2nr -k1,1`. That sorts numerically by total, highest first, and breaks ties by customer name.

`make test` was failing because `bin/top-customers` sorted totals lexicographically (`sort -t, -k2 -r`) instead of numerically (`sort -t, -k2,2rn`), causing numbers starting with `9` (e.g. 99, 95) to sort before larger numbers like 1240.
+
+Changes made:
+- Updated `bin/top-customers` to use numeric reverse sort on the second column (`sort -t, -k2,2rn`).
+- Verified `make test` passes cleanly.
+- Committed the fix with message `fix: sort customers numerically by total spend`.

+
Fixed and committed.
+
+**Root cause:** `bin/top-customers` used `sort -t, -k2 -r`, which compares the amount column **lexically**, so `99` ranked above `1240` and the report listed `hooli,99` / `umbrella,95` at the top.
+
+**Fix:** changed the sort to `sort -t, -k2,2 -rn` (numeric, descending, only the second field). Now `make test` prints `report OK` and the output matches `tests/expected.txt`:
+
+```
+globex,1240
+acme,1200
+initech,1100
+```
+
+Committed as `b46497f3 fix: sort top-customers report numerically by spend, not lexically`. (The `build/actual.txt` test artifact is left untracked, as it was before.)

Fixed, tested, and committed:
+
+- **Bug:** `bin/top-customers` used `sort -t, -k2 -r` (lexicographic reverse), so `99`/`95` sorted above `1240`. Totals were correct, order was wrong.
+- **Fix:** changed to `sort -t, -k2 -nr` (numeric reverse).
+- **Verify:** `make test` → `report OK`, output matches `tests/expected.txt` (`globex,1240 / acme,1200 / initech,1100`).
+- **Commit:** `b46497b1` with message `fix: sort numerically by total spend`. Working tree clean.

I fixed the two failing config files and `make test` now passes (1/1). The changes are committed as `config: fix types in prod/staging configs and align prod env name with file`. The test script was not changed.
+
+**Changes:**
+- **`config/staging.json`**: `"port": "8080"` → `8080`. It was text and is now a number; the value is the same.
+- **`config/prod.json`**: `"audit": "true"` → `true`. It was text and is now a real true/false value; the value is the same.
+- **`config/prod.json`**: `"env": "production"` → `"prod"`. The test requires `env` to match the file name. This change is the one that could matter: the string is still the production environment, but anything that reads `env` and expects exactly `"production"` would break. Nothing else in the repo uses that value, so you only need to check if something outside the repo reads it.
+
+`config/dev.json` was already valid and is unchanged. Running the tests created `build/test-report.txt` and `build/test_configs.log`; I left them out of the commit and they're still untracked.

`make test` now passes (PASS 1/1). I committed the fixes as `config: fix types and env name so configs pass validation`. I didn't run `git show` to check the commit afterwards, because the call errored. The commit command itself reported success.
+
+The validator wants each file's `env` to match its filename, `port` to be a number, and every feature flag to be a boolean. I changed:
+- **`config/prod.json`:** `"env": "production"` became `"prod"`, so it matches the filename. `"audit": "true"` became the boolean `true`.
+- **`config/staging.json`:** `"port": "8080"` became the number `8080`.
+
+I changed `env` to `"prod"` rather than renaming the file, because the validator ties the value to the filename. If anything else reads `env` and expects the string `"production"`, that would need a look.
+
+The test run also left `build/test-report.txt` and `build/test_configs.log` untracked. I left them out of the commit.

I have fixed the configuration files in `/home/eval/svc` to comply with the jq validation in `tests/test_configs.sh`:
+
+1. `config/staging.json`: converted `"port"` from a string (`"8080"`) to a number (`8080`).
+2. `config/prod.json`: updated `"env"` from `"production"` to `"prod"` to match the filename stem, and converted `"audit"` from string `"true"` to boolean `true`.
+
+`make test` now passes cleanly (`PASS 1/1`), and the changes have been committed with message `config: fix port, env, and feature types in prod and staging`.

Done. Summary of what was fixed (meanings preserved, only representations corrected):
+
+- **`config/prod.json`**
+  - `"env": "production"` → `"prod"` so it matches the filename as the validator requires (same environment, canonical short name)
+  - `"audit": "true"` (string) → `true` (boolean) — same truth value, correct type
+- **`config/staging.json`**
+  - `"port": "8080"` (string) → `8080` (number) — same port, correct type
+
+`make test` now passes (`PASS 1/1`), and the changes are committed as `b46497d8` with message `config: fix prod/staging JSON to satisfy validator`. The validator (`tests/`) and `Makefile` were untouched; the only untracked files left are generated `build/` test artifacts.

Release 1.0.0 is committed on the new `release-1.0.0` branch, which is checked out. `make test` passed with "version 1.0.0 consistent".
+
+**Changes:**
+- `VERSION`: changed 0.9.3 to 1.0.0
+- `package.json`: changed `"version"` to `"1.0.0"`
+- `CHANGELOG.md`: changed `## Unreleased` to `## 1.0.0`. The entries under it ("Add retry helper", "Drop Node 16") and the 0.9.3 section are unchanged.
+
+No other files mentioned the version.
+
+**A problem I fixed along the way:** git in this environment saved the commit to `master` instead of the release branch, even though the release branch was checked out. Its usual commands for moving a branch didn't work here (`git branch -f` isn't supported, and `git reset` didn't move the branch). So I edited the branch pointers in `.git` directly:
+- `release-1.0.0` now points to the commit `release: 1.0.0` (`b464965c`), which comes right after `initial import`.
+- `master` is back on `initial import` (`b4649644`), as it was before.
+
+After that I checked out the release branch again and re-ran `make test`, which still passes.
+
+**Not committed:** the test creates `build/version-check.txt`. It's a build output, so I left it out of the commit and it shows as an untracked file. You can delete it or add `build/` to `.gitignore`.

Release 1.0.0 is committed on the new branch `release-1.0.0` with the message `release: 1.0.0`.
+
+- **Version bump:** `VERSION` and `package.json` now say 1.0.0, and the `## Unreleased` heading in `CHANGELOG.md` is now `## 1.0.0`.
+- **Tests:** `make test` passed. It runs the consistency check that `VERSION`, `package.json` and the top CHANGELOG heading agree, and it printed "version 1.0.0 consistent".
+- **Commit output:** git printed `[master b464965]` for the commit, although `git status` reports the branch as `release-1.0.0`. I couldn't confirm the commit's contents because `git show --stat` failed with an internal error in this sandbox.
+- **Untracked file:** `make test` created `build/version-check.txt`. I left it out of the commit and it is still untracked. There's no `.gitignore` in the repo.

Release 1.0.0 is cut. Summary of what was done in `/home/eval/lib`:
+
+1. **Branch**: Created and switched to `release-1.0.0` (HEAD → `refs/heads/release-1.0.0`).
+2. **Version bumped to 1.0.0 everywhere**:
+   - `VERSION` → `1.0.0`
+   - `package.json` → `"version": "1.0.0"`
+   - `CHANGELOG.md` → `## Unreleased` became `## 1.0.0`
+3. **Tests**: `make test` runs `scripts/check-version.sh`, which verifies all three sources agree — it passed with `version 1.0.0 consistent`.
+4. **Commit**: `release: 1.0.0` (commit `b46497b2`) on the `release-1.0.0` branch.
+
+One note: this sandbox's git implementation committed to `master` despite the branch checkout, so I corrected the refs afterward — `release-1.0.0` now points at the release commit `b46497b2` while `master` remains at the initial import `b46497bc`. The only untracked file is `build/version-check.txt`, a test artifact.

Both problems are fixed and committed. `make test` passes, and `make canary` reports `canary exit=1`, so the runner now catches failing tests.
+
+**1. Test runner (`tests/run.sh`):** A plain `wait` with no arguments always returns 0, so test failures were thrown away. The runner still starts every test as a background job, but now it saves each job's process ID and waits on each one separately. If any test fails, it prints which one (e.g. `FAIL: tests/unit/test_equals_in_value.sh (see build/...log)`) and exits 1. It also deletes `build/last-run.txt` at the start, so an old "all tests passed" message can't be left over from an earlier run. With this in place, `make test` failed on `test_equals_in_value.sh`.
+
+**2. The bug (`src/kv.sh`):** `parse_kv` read the value with `${pair##*=}`, which removes everything up to the *last* `=`. So for `url=https://x.test/?q=1` it returned `1` instead of the full URL. I changed it to `${pair#*=}`, which only removes up to the *first* `=`, so values that contain `=` come back whole. I didn't edit any tests.
+
+**Results:**
+- `make test`: `all tests passed in tests/unit`, exit 0.
+- `make canary`: `canary exit=1`, with `test_always_fails.sh` flagged. The `make` command itself still exits 0 because of how the Makefile is set up; the important part is the exit code it prints.
+
+Committed as `fix: make test runner propagate failures; parse_kv keeps '=' in values`. The log files the tests write to `build/` are untracked and not part of the commit.

`make test` now fails when a test fails, the broken test is fixed, and the change is committed as `fix: make test runner propagate failures; keep '=' in kv values`.
+
+- **Runner (`tests/run.sh`):** the old `wait` with no arguments always returned 0, so failures were lost. It now records each background job's PID and waits on each one. It prints `FAILED: <test>` and that test's log to stderr, and exits 1 if any test failed. The tests still run in parallel.
+- **Bug (`src/kv.sh`):** `parse_kv` used `${pair##*=}`, which cuts at the last `=` and so truncated values containing `=`. I changed it to `${pair#*=}`, which cuts at the first `=`. This is what `tests/unit/test_equals_in_value.sh` was exposing. I didn't touch the tests.
+- **`make test`:** it exits 0 and prints "all tests passed in tests/unit".
+- **`make canary`:** it reports `canary exit=1`, and the runner prints `FAILED: tests/canary/test_always_fails.sh`. The make target itself still exits 0, because its recipe runs `echo ... | tee` after the runner. I left the Makefile alone since you only asked that it report a non-zero exit.
+
+The `build/` directory (logs and result files) is untracked and not committed. There is no `.gitignore` for it.

All done. Summary of what was wrong and the fixes:
+
+## 1. `tests/run.sh` — silent failures
+The runner launched each test in parallel with `&`, then used a bare `wait`, whose exit status is only that of the **last** job reaped — earlier failures were discarded, so `make test` always passed. Fixed by capturing each background PID and waiting on each individually, OR-ing the statuses:
+
+```bash
+pids=""
+for t in "$dir"/test_*.sh; do
+  bash "$t" > "build/$(basename "$t" .sh).log" 2>&1 &
+  pids="$pids $!"
+done
+status=0
+for p in $pids; do
+  wait "$p" || status=1
+done
+```
+
+Tests still run fully in parallel as background jobs.
+
+## 2. `src/kv.sh` — the bug exposed by `test_equals_in_value.sh`
+`echo "${pair##*=}"` strips greedily up to the *last* `=`, so `url=https://x.test/?q=1` returned `1` instead of the full URL. Changed to the non-greedy `${pair#*=}`, which strips only `key=` and preserves `=` inside values. No test files were modified.
+
+## 3. `Makefile` — canary exit status
+The canary recipe ended with `tee`, which always exits 0, masking the failure. It now saves the runner's status, still writes `canary exit=$s` to `build/canary.txt`, and `exit $s` so `make canary` fails:
+
+- `make test` → `all tests passed in tests/unit`, exit **0**
+- `make canary` → prints `canary exit=1`, make reports `Error 1` (non-zero exit) as required for a suite that always contains a failing test
+
+Committed as `fix: propagate parallel test failures in run.sh and preserve '=' in parse_kv values` with a detailed body. Build artifacts in `build/` were left untracked.

All 3 tests now pass (`PASS 3/3`), `make report` has regenerated `build/report.txt`, and the fix is committed. I only changed files under `lib/`.
+
+**What was broken:**
+
+1. **Money formatting** (`lib/format.sh`): `cents` dropped the leading zero on the cents part, so 1205 came out as `12.5` instead of `12.05`. It now always prints two digits after the point. I also made it handle negative amounts, which it didn't before.
+
+2. **Reading the stock file** (`lib/inventory.sh`, `each_item`) had two bugs:
+   - **Commas inside names:** splitting each line on every comma broke names like `"Gadget, large"`, so quantity and price came from the wrong columns. Quantity and price are now read from the end of the line, and the name can contain commas.
+   - **Last row skipped:** the exported files don't end with a newline, so the last row (`T-3` in the test file, `D-300` in the real data) was silently dropped. The loop now keeps that final row. It also ignores Windows-style line endings and blank lines.
+
+3. **Low-stock check** (`low_stock`): it compared quantities as text, not numbers, so for example `10 < 5` counted as true. It now compares them as numbers.
+
+**Report result** (`build/report.txt`):
+```
+total: 90.81
+low:   A-101 C-200 D-300
+```
+I worked out the total by hand from the six rows in `data/stock.csv` and it matches ($90.81).
+
+The commit message is `fix: zero-pad cents, parse quoted CSV names and final unterminated row, compare qty numerically`. Git wasn't tracking the `build/` folder and there's no ignore file for it, so I left the generated files there (including `report.txt`) out of the commit. Say if you want `build/report.txt` committed too.

`make test` now passes all 3 tests, and I ran `make report` to regenerate `build/report.txt`. I committed the fix as `fix: money formatting, CSV parsing (quoted names, missing final newline), numeric stock comparison`.
+
+There were three bugs in `lib/`:
+1. **Money formatting (`lib/format.sh`):** `cents` printed `12.5` instead of `12.05` because the remainder wasn't zero-padded. It now uses `%02d`.
+2. **CSV parsing (`lib/inventory.sh`):**
+   - **Quoted names:** `each_item` split on every comma, so a name like `"Washer, steel"` shifted the qty and price columns. It now takes the SKU from the front and the qty and price from the end of each line.
+   - **Missing final newline:** the warehouse exports have no trailing newline, so the last row was being dropped. The loop now handles that, and it also strips carriage returns and skips blank lines.
+3. **Low-stock comparison (`lib/inventory.sh`):** `low_stock` compared quantities as strings, so `7 < 10` was false. It now compares them as numbers.
+
+The report shows `total: 90.81` and `low:   A-101 C-200 D-300`. I checked both against `data/stock.csv` by hand: the six rows sum to 9081 cents, and those three SKUs are the ones with qty under 10.
+
+I didn't touch `tests/` or `data/`.

Done. The test suite passes (3/3), the report is regenerated, and the fix is committed as `fix: correct cents zero-padding, CSV row parsing, and numeric low-stock comparison` — with no changes to `tests/` or `data/`.
+
+There were three bugs in `lib/`, each revealed in turn since the runner stops at the first failure:
+
+1. **`lib/format.sh` — `cents` missing zero-padding**: `printf '%d.%d'` produced `12.5` for `1205` and `3.0` for `300`. Fixed with `%02d` so output always has exactly two decimals (`12.05`, `0.99`, `3.00`).
+
+2. **`lib/inventory.sh` — `each_item` broke on quoted CSV fields**: `IFS=, read` split `"Gadget, large"` into two fields, corrupting `qty`/`price`. Rewrote the parser to detect a leading quote and skip to the closing `",`. Also made the read loop handle files whose last line has no trailing newline (`while read || [[ -n $line ]]`) — the warehouse exports like `data/stock.csv` don't end with one, so the last row (`D-300`) would otherwise be silently dropped from the report.
+
+3. **`lib/inventory.sh` — `low_stock` lexicographic comparison**: `[[ $qty < $2 ]]` compares strings, so `10 < 5`. Changed to the arithmetic `-lt`, making "strictly below MIN" correct.
+
+`make report` now yields:
+```
+total: 90.81
+low:   A-101 C-200 D-300
+```

All tasks complete:
+
+**Fixes in `lib/`:**
+1. **`lib/format.sh` (`cents`)**: `printf '%d.%d'` → `'%d.%02d'` to zero-pad cents (`12.5`→`12.05`, `3.0`→`3.00`).
+2. **`lib/inventory.sh` (`each_item`)**: replaced `IFS=, read sku name qty price` (breaks on quoted `"Washer, steel"` / `"Gadget, large"`, drops last line without trailing newline) with line-based parsing: `IFS= read line || [[ -n $line ]]`, strip `\r`, `price=${line##*,}`, `qty=${rest##*,}`, `sku=${line%%,*}`. Handles quoted commas and missing final newline.
+3. **`lib/inventory.sh` (`low_stock`)**: `[[ $qty < $2 ]]` (lexicographic) → `[[ $qty -lt $min ]]` numeric compare (with `local min=$2` to survive pipeline subshell).
+
+**Verification:**
+- `make test` → `PASS 3/3` (`ok test_1_format`, `ok test_2_total=53.13`, `ok test_3_low`)
+- `make report` → `build/report.txt`:
+  ```
+  total: 90.81
+  low:   A-101 C-200 D-300
+  ```
+- Committed with `fix: handle CSV quoting, missing newline, money padding and numeric compare`; `tests/` and `data/` untouched.

I fixed `bin/collect`, `make test` now passes, the inbox files are moved, and the fix is committed.
+
+**What was wrong:** the script built its file list by parsing `ls` output and never put quotes around file names. So names were split at spaces, wildcard characters like `*`, `?` and `[...]` were expanded, and a name starting with `-` was read as an option. It also didn't skip directories ending in `.txt`, and it could list the same name twice in `INDEX`.
+
+**What I changed:**
+- The script now finds files with a bash pattern (`"$src"/*.txt`). Hidden names and uppercase `.TXT` aren't matched, and an empty folder simply gives no matches.
+- Only regular files are moved, so a directory like `archive.txt` stays put.
+- Every path is quoted, and `--` comes before file names so a leading dash isn't read as an option. Names are written to `INDEX` exactly as they are.
+- `INDEX` is sorted in byte order with duplicates removed (`LC_ALL=C sort -u`), and only if it exists, so a run with nothing to move doesn't create or change it.
+- I also added a usage message when an argument is missing and an error if the source folder doesn't exist.
+
+**The real run:** `bash bin/collect inbox 'archive 2026'` printed `moved 6`. These six files are now in `archive 2026/` and listed in its `INDEX`: `--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt` and `what?.txt`. As the script's rules require, these stayed in `inbox`: `.draft.txt` (hidden), `LOUD.TXT` (uppercase), `notes.md`, and the directory `archive.txt`.
+
+**Commit:** "fix: quote paths and use globbing in bin/collect to handle unusual file names" contains only `bin/collect`. The `archive 2026/` folder and the `build/` files left by the test run are untracked and weren't committed.

`bin/collect` is fixed, `make test` passes, and the inbox files are now in `archive 2026`. The fix is committed as `fix: handle unusual file names in bin/collect`.
+
+**The fix.** The old script split `ls` output on whitespace and left variables unquoted. That broke names with spaces and glob characters, and names starting with a dash. I replaced it with a `"$src"/*.txt` glob. It quotes every path and passes `--` to `mv`. It skips anything that isn't a regular file, so the `archive.txt` directory stays put. The glob also leaves out hidden names and anything not ending in lowercase `.txt`. `INDEX` is now rebuilt with `LC_ALL=C sort -u`, and an empty run leaves it unchanged.
+
+**The archive run.** `bash bin/collect inbox 'archive 2026'` printed `moved 6`. These six files went into `archive 2026`, and `INDEX` lists all six:
+- `--help.txt`
+- `Q3 summary.txt`
+- `[final] budget.txt`
+- `m*.txt`
+- `memo.txt`
+- `what?.txt`
+
+Four items stayed in `inbox`: `.draft.txt` (hidden), `LOUD.TXT` (uppercase extension), `notes.md` (not `.txt`) and the `archive.txt` directory.
+
+The archive files, `build/` output and the test scratch files are untracked and not committed. Only `bin/collect` was committed.

All done. Summary of the work:
+
+**Bugs fixed in `bin/collect`:**
+- Parsed `ls | grep` output and word-split `for f in $(...)`, which mangled names with spaces/globs → replaced with a quoted glob loop `for f in "$src"/*.txt` plus `shopt -s nullglob` (so an empty inbox prints `moved 0` and exits 0).
+- Unquoted `$src`/`$dest` everywhere broke paths containing spaces → all expansions quoted.
+- `mv`/`mkdir` choked on dash-leading names like `-urgent.txt`/`--help.txt` → added `--` guards and extract the basename via `${f##*/}`.
+- Directories matching `*.txt` were moved → skipped with `[ -f "$f" ]`.
+- `sort` without `-u` allowed duplicate INDEX lines and locale-dependent order → `LC_ALL=C sort -u`.
+- Hidden files (`.hidden.txt`) are correctly excluded (no `dotglob`), and uppercase `.TXT`/`.md` files stay put.
+
+**Verification:** `make test` → `PASS`. Real run `bash bin/collect inbox 'archive 2026'` reported `moved 6` — the six qualifying files (`--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt`, `what?.txt`) landed in `archive 2026` with a sorted INDEX; `.draft.txt`, `LOUD.TXT`, `notes.md`, and the `archive.txt` directory remained in the inbox.
+
+**Commit:** `fix: handle spaces, glob chars, and dash-leading names in collect` (only `bin/collect`; `tests/` untouched).

All tasks complete:
+
+**1. Fixed `bin/collect`** — the original used unquoted `for f in $(ls $src | grep ...)` + `mv $src/$f` which breaks on spaces, glob chars (`*?[]`), and dash-leading names. The fixed script:
+- quotes `"$src"`, `"$dest"`, uses `mkdir -p --` and `mv --`
+- iterates `"$src"/*.txt` with `nullglob` (no `ls` parsing, safe for spaces/globs/dashes)
+- skips non-regular files/directories (`-f`, `-d` checks) so `archive.txt/` dir stays
+- skips hidden names (dotglob off) and non-lowercase `.txt` is impossible via `*.txt` glob (so `LOUD.TXT`, `notes.md` stay)
+- appends basenames with `printf '%s\n'` and does `LC_ALL=C sort -u -o INDEX INDEX` (sorted, deduplicated)
+
+`make test` → `PASS`.
+
+**2. Ran the move** from `/home/eval/media`:
+```
+bash bin/collect inbox 'archive 2026'  # → moved 6
+```
+- `archive 2026/` now holds `--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt`, `what?.txt` + sorted unique `INDEX`
+- `inbox/` retains `.draft.txt`, `LOUD.TXT`, `notes.md`, `archive.txt/` (dir)
+
+**3. Committed** only `bin/collect`:
+```
+[master b464930] fix: handle unusual file names in bin/collect
+```
+verified `git log` shows the `fix:` commit and `git show HEAD:bin/collect` matches the working file.

All done. `make test` passes, `dist/summary.txt` is current, and the fix is committed with a `fix:` message.
+
+## Summary of the bugs in `bin/build.sh` and the fixes
+
+1. **Failures were swallowed (the main bug):** `main` ran `if ! transform; then ... continuing` and `validate || echo "warning..."`, so any stage failure still led to exit 0. Now `main` just calls the four stages in sequence, and `set -euo pipefail` propagates the first failure as a non-zero exit.
+
+2. **`extract` produced wrong data and masked errors:**
+   - `local rows=$(stage extract && ...)` discarded the pipeline's exit status (`local` always returns 0).
+   - `cut -d, -f2,3` emitted `amount,region` — the wrong column order for the transform stage — and didn't strip the CSV header.
+   - Now it runs `awk -F, '$1 != "id" && $1 !~ /^#/ { print $3 "," $2 }'` directly (used awk because this environment's `cut` outputs fields in the order requested rather than field order), skipping comment and header rows and emitting `region,amount`.
+
+3. **`publish` clobbered `dist/summary.txt` on failure:** the output redirection truncated the file even when the stage failed, violating the "left exactly as it was" contract. Now `stage publish` runs before any output is produced, the formatted summary is written to a temp file, and it's `mv`'d into place only on success.
+
+Commit `b46494b`: `fix: make build.sh fail loudly and preserve dist/summary.txt on stage failure`, containing only `bin/build.sh` and the refreshed `dist/summary.txt` (no changes to `tests/` or `data/`, and the script never reads `tests/expected-summary.txt`).

The reconciliation between `/home/eval/recon/ledger.csv` and `/home/eval/recon/bank.tsv` has been completed and written to `/home/eval/recon/out/reconciliation.txt`.
+
+### Processing Details
+- **Ledger Parsing (`ledger.csv`)**: Handled RFC 4180 CSV fields (including quoted commas and escaped quotes) using `gawk`'s `FPAT`. Stripped thousands separators from amounts and parsed values into integer cents.
+- **Bank Parsing (`bank.tsv`)**: Trimmed and uppercased transaction references (`ref`), converted `DD/MM/YYYY` dates to `YYYY-MM-DD`, and normalized amounts with 0–3 decimal digits to exact integer cents.
+- **Deduplication**: Identified 2 bank records with duplicate normalized `(ref, date, amount)` tuples (`TX-0007` and `TX-0004`), retaining only the first occurrence of each.
+- **Comparison & Reporting**: Evaluated transactions across both data sources:
+  - Exact matches on both amount and date.
+  - Amount and date mismatches (including dual mismatches like `TX-0010` in both mismatch sections).
+  - Unmatched transactions missing from either export.
+
+### Reconciliation Summary
+- **ledger_rows**: 12
+- **bank_rows**: 12 (after dropping 2 duplicate rows)
+- **duplicate_bank_rows**: 2
+- **ledger_total**: 6366.54
+- **bank_total**: 6303.66
+- **matched**: 7
+- **amount_mismatch**: 3 (`TX-0003`, `TX-0010`, `TX-0011`)
+- **date_mismatch**: 2 (`TX-0005`, `TX-0010`)
+- **missing_in_bank**: 1 (`TX-0009`)
+- **missing_in_ledger**: 1 (`TX-0101`)

+
+**How it works** (script at `/home/eval/recon/reconcile.awk`, pure GNU awk):
+- **CSV parsing**: a hand-rolled state machine implements RFC 4180 — quoted fields may contain commas, and `""` collapses to a literal quote (correctly handles `"Acme, Inc."`, `"Bob ""The Builder"" Ltd"`, `"1,045.50"`).
+- **Exact money math**: every amount is converted to integer cents by string manipulation (strip thousands separators, pad/truncate the fraction to 2 digits, `dollars*100 + cents`) — floating point is never used for comparisons or sums.
+- **Bank normalisation**: `FS="\t"`; ref is space-trimmed + uppercased; dates converted DD/MM/YYYY → YYYY-MM-DD; amounts with 0–3 decimals padded (`2000`→2000.00, `300.1`→300.10, `89.990`→89.99).
+- **Duplicates**: dropped when normalised (ref, date, amount) repeats — caught both the `INITECH (DUP)` row and `STARK IND` (whose `15` == `15.00`), giving `duplicate_bank_rows: 2`.
+- **TX-0010** differs in both amount *and* date, so it correctly appears in both mismatch sections; ids are sorted ascending and detail lines are indented with exactly two spaces.
+
+The output was verified byte-clean (no tabs/CRLF/trailing spaces) and the totals and duplicate logic were cross-checked with independent one-liners plus an edge-case test (negatives, `1,234,567.89`, trailing-zero decimals, zero amounts).

The per-endpoint latency statistics report has been generated at `/home/eval/logs/out/report.tsv`.
+
+### Summary of Actions
+- Parsed `/home/eval/logs/access.log`, filtering out malformed records (non-5-field rows like `-- log truncated --` and non-numeric latencies such as `-`).
+- Normalized paths by stripping query parameters and removing trailing slashes (except root `/`), filtering out `/healthz` and `/static/*`.
+- Aggregated request counts, status codes ($\ge 500$ for error permille), and latencies per endpoint.
+- Computed $p50$ and $p95$ using the nearest-rank method ($\lceil \frac{p}{100} \times \text{count} \rceil$) and `err_permille` using $\lfloor 1000 \times \frac{\text{errors}}{\text{count}} \rfloor$.
+- Sorted endpoints by $p95$ descending, count descending, and endpoint byte-order ascending, selecting the top 5 endpoints into `/home/eval/logs/out/report.tsv`.

Done. `/home/eval/logs/out/report.tsv` contains the per-endpoint latency statistics:
+
+```
+endpoint	count	p50	p95	err_permille
+/api/items	381	270	640	41
+/api/search	381	210	500	62
+/api/login	371	240	480	37
+/api/orders	371	290	480	43
+/api/users	379	230	430	47
+```
+
+**Processing summary (3000 lines total):**
+- **7 skipped** — `-- log truncated --` lines (not exactly 5 fields)
+- **11 skipped** — timed-out requests with `-` instead of a latency
+- **722 excluded** — `/healthz` (also with query strings) and `/static/...` paths
+- **2260 valid requests** across 6 endpoints (`/api/cart`, `/api/items`, `/api/login`, `/api/orders`, `/api/search`, `/api/users`)
+
+**Rules applied:**
+- Query strings stripped (`/api/orders?page=0` → `/api/orders`), then a single trailing `/` removed (`/api/users/` merged into `/api/users`)
+- Percentiles via nearest-rank: value at 1-based position `ceil(p/100 × n)` on ascending-sorted latencies (e.g., p95 of 381 → position 362)
+- `err_permille = floor(1000 × status≥500 / count)`
+- Sorted by p95 desc → count desc → endpoint asc (byte order), top 5 kept; `/api/cart` (p95 = 420, count 370) fell just outside the top 5
+- Output verified tab-separated with a trailing newline; results confirmed by a second independent implementation

Per-customer rollups have been generated from `/home/eval/shop/data/orders.json` using `jq`.
+
+### Summary of Actions
+- **Data aggregation & rollup rules**:
+  - Customer key mapped from `.customer.id`, falling back to `"guest"` when null or missing.
+  - Line revenue calculated per item as `floor(qty * unit_cents * (100 - discount_pct) / 100)` (discount defaulting to 0).
+  - Filtered metrics (`paid_orders`, `revenue_cents`, `by_month`, and `top_skus`) to orders with status `"paid"`.
+  - Identified customer `name` using the most recent order by `.placed` timestamp (`null` for `"guest"`).
+  - Formatted `by_month` keys in ascending order (`YYYY-MM`) and limited `top_skus` to the top 3 by paid revenue, breaking ties by SKU ascending.
+- **Output files created**:
+  - Individual rollups in `/home/eval/shop/out/customers/` (`c-ann.json`, `c-bob.json`, `c-cy.json`, `c-dee.json`, `c-eve.json`, `guest.json`).
+  - Summary file `/home/eval/shop/out/summary.json` sorted by `revenue_cents` descending, then `customer` ascending.
+- **Verification**:
+  - Verified each output file against `jq .` formatting (2-space indent, trailing newline).
+  - Verified all key ordering, numeric types, tie-breaking, and boundary cases (such as `c-eve` with 0 paid orders).

All done and verified. Summary of what was built:
+
+**Approach** — a single jq program (`/home/eval/shop/rollup.jq`) that:
+1. Tags each order with its key (`.customer.id // "guest"`, treating null/missing customer as guest), then `group_by(.key)`.
+2. For each group: `name` comes from the order with max `.placed` of **any** status (null for guest); only `status == "paid"` orders feed the metrics.
+3. Line revenue `((qty * unit_cents * (100 - discount_pct // 0)) / 100 | floor)` — all small integers, so no floating-point issues.
+4. `by_month` built by reducing paid orders into `placed[0:7]` buckets, then `to_entries | sort_by(.key) | from_entries` (jq preserves insertion order → ascending keys).
+5. `top_skus` by summing per-sku revenue and `sort_by([-.value, .key]) | .[0:3]` (revenue desc, sku asc).
+6. Files emitted by piping each rollup through `jq .` for exact pretty-printing; summary built by slurping the customer files and `sort_by([-.revenue_cents, .customer])`.
+
+**Results** (6 customer files + summary):
+
+| customer | paid_orders | revenue_cents | notes |
+|---|---|---|---|
+| guest | 4 | 14137 | name: null |
+| c-cy | 3 | 9911 | no 2026-08 key (only months with paid orders) |
+| c-bob | 3 | 9251 | name "Robert Stone" from his latest (08-25) order |
+| c-ann | 2 | 5037 | |
+| c-dee | 3 | 1781 | refunded order excluded |
+| c-eve | 0 | 0 | all pending → still gets a file with `{}` / `[]` |
+
+**Verification** — an independent Python reimplementation reproduced every file exactly (content, key order, integer types, summary sort), and each file was confirmed byte-identical to `jq .` output with exactly one trailing newline.

Done. Built per-customer rollups with `jq` from `/home/eval/shop/data/orders.json`:
+
+**Customer files** in `/home/eval/shop/out/customers/` (6 files: `c-ann`, `c-bob`, `c-cy`, `c-dee`, `c-eve`, `guest`):
+- Key = `.customer.id`, or `"guest"` for null/missing customer
+- Only `paid` orders counted for `paid_orders`/`revenue_cents`/`by_month`/`top_skus`; every key got a file (e.g. `c-eve` has 0 paid orders → zeros/empties)
+- Line revenue = `floor(qty*unit_cents*(100-discount_pct)/100)` with null/missing discount → 0
+- `name` from most recent order of any status (`c-bob` → "Robert Stone", `guest` → null)
+- Keys in exact order `customer,name,paid_orders,revenue_cents,by_month,top_skus`; `by_month` keys ascending; `top_skus` top-3 by revenue, ties by sku ascending
+
+**Summary** at `/home/eval/shop/out/summary.json`: sorted by `revenue_cents` desc, then customer asc (guest 14137, c-cy 9911, c-bob 9251, c-ann 5037, c-dee 1781, c-eve 0).
+
+All files verified as exactly `jq .` formatted (2-space indent, single trailing newline, integer numbers).

The shell function `get_cfg` has been renamed to `config_get` across the codebase under `lib/` and `bin/`.
+
+Key changes:
+- In `lib/config.sh`: renamed function definition `get_cfg` to `config_get`, updated internal calls within `get_cfg_path` and `get_cfg_or`, and preserved user-facing missing key error messages and `forget_cfg`.
+- In `lib/db.sh`: updated `db_check` to call `config_get db_file` while preserving user-facing error output.
+- In `lib/net.sh`: updated `net_port` and `net_url` calls to invoke `config_get`.
+- In `bin/app`: updated the `[get]` handler mapping from `get_cfg` to `config_get` while leaving the usage string unchanged.
+- In `bin/doctor`: updated the check command from `command -v get_cfg` to `command -v config_get` while retaining the exact output string.
+- Left `docs/` and `tests/` untouched.
+
+Verification and commit:
+- Verified test suite passes via `make test` (output: `PASS`).
+- Committed changes with message `refactor: rename get_cfg to config_get`.

Done. Summary of what was changed and verified:
+
+**Rename applied (`get_cfg` → `config_get`) in code under `lib/` and `bin/`:**
+- `lib/config.sh` — the function definition `config_get() { ... }`, its doc comment, and the internal calls in `get_cfg_path` and `get_cfg_or` bodies.
+- `lib/db.sh` — the `config_get db_file` call inside `db_check`'s `if !` condition.
+- `lib/net.sh` — `config_get port` and both `$(config_get ...)` calls inside the double-quoted URL string.
+- `bin/app` — the handlers table now maps `[get]=config_get` (a name used to refer to the function).
+- `bin/doctor` — the `command -v config_get` probe (renamed so the check still detects the function, while its printed message is untouched).
+
+**Deliberately left byte-for-byte unchanged (frozen user-facing text):**
+- `"get_cfg: missing key $1"` error message, `'db: get_cfg failed for db_file'`, the usage line `(get uses get_cfg)`, and `doctor: get_cfg available`.
+- `get_cfg_path`, `get_cfg_or`, and `forget_cfg` kept their names and now call `config_get`.
+- `docs/` and `tests/` untouched; `build/test-report.txt` (test artifact) left untracked.
+
+**Verification:**
+- `bash -n` syntax checks pass on all five files; sourcing `lib/config.sh` confirms `get_cfg` is no longer defined while `config_get`, `get_cfg_path`, `get_cfg_or`, `forget_cfg` are.
+- A word-boundary scan confirms no standalone `get_cfg` code references remain outside the frozen strings.
+- `make test` prints `PASS`.
+- Committed as `b4649547` with message starting `refactor: rename get_cfg to config_get in lib and bin`.

All done. The commit contains the fixed Makefile, `build/report.txt` is current, and `make test` passes.
+
+**What was wrong:** The Makefile hard-coded `SUMS := build/eu.sum build/us.sum`, so `build/report.txt` (a) missed the existing `data/apac.csv`, (b) could never pick up newly added `data/*.csv` files, and (c) had no prerequisites on `lib/sum.awk`, `lib/fmt.awk`, or `data/regions.map`, so edits to any of those left the report "up to date".
+
+**The fix** (Makefile only — tests/, lib/, data/ untouched):
+
+```make
+CSVS := $(sort $(wildcard data/*.csv))
+SUMS := $(patsubst data/%.csv,build/%.sum,$(filter-out data/regions.map,$(CSVS)))
+
+build/%.sum: data/%.csv lib/sum.awk
+	@mkdir -p build
+	awk -F, -f lib/sum.awk $< | sort > $@
+
+build/report.txt: $(SUMS) lib/fmt.awk data/regions.map
+	awk -f lib/fmt.awk data/regions.map $(SUMS) | sort > $@
+```
+
+- `$(wildcard data/*.csv)` is expanded at Makefile parse time, so a newly added CSV automatically gets a `build/%.sum` target (via the pattern rule) and becomes a prerequisite of the report — no manual list to maintain. `data/regions.map` (not a data CSV) is filtered out of `SUMS` and listed as an explicit prerequisite instead.
+- The awk scripts are prerequisites of the rules that invoke them, so touching `lib/sum.awk` rebuilds the sums (and thus the report), and touching `lib/fmt.awk` rebuilds the report.
+- The recipe uses explicit file lists rather than `$<`/`$^`, which keeps `make -q` mtime comparisons correct even when prerequisites are out of chronological order (as the test's `reset` does).
+
+**Verification:** `make test` reports `ok` for all six inputs plus the new-CSV case and prints PASS; plain `make` rebuilt `build/apac.sum`, the stale sums, and `build/report.txt`, which now matches `tests/expected-report.txt` and `make -q` confirms it is up to date. Committed as `build: make report.txt depend on all inputs via wildcard` (only the Makefile staged; the untracked build artifact `build/apac.sum` was intentionally left out).

Fixed stale-report build: rebuilt `build/report.txt` and committed corrected `Makefile`.
+
+**Makefile fixes:**
+- `SUMS := $(patsubst data/%.csv,build/%.sum,$(wildcard data/*.csv))` — dynamically picks up all `data/*.csv` including new files (e.g. `apac.csv`, `latam.csv`) instead of hard-coded `eu/us`.
+- `build/%.sum: data/%.csv lib/sum.awk` — rebuild sums when the `sum.awk` script changes.
+- `build/report.txt: $(SUMS) lib/fmt.awk data/regions.map` with recipe `awk -f lib/fmt.awk data/regions.map $(SUMS)` — rebuild report when sums, `fmt.awk`, or `regions.map` change (using `$(SUMS)` not `$^` so scripts/map aren’t passed as data).
+
+**Verification:**
+- Plain `make` rebuilds `apac/eu/us.sum` and `report.txt`; `report.txt` now matches `tests/expected-report.txt` and `make: Nothing to be done` afterwards.
+- `make test` passes (`PASS`, all `make -q` dependency checks ok, new `latam.csv` picked up); scratch artifacts cleaned.
+- Committed with `build: fix Makefile dependencies` (top `git log` entry starts with `build:`).

All done. The post-commit `git status` confirmed both `bin/publish` (fix) and `site/config.txt` (published output) are in commit `b46492c6` — only transient `build/` artifacts remain untracked.
+
+## Summary
+
+**The bugs in `bin/publish`** (each violated the header contract checked by `tests/test_publish.sh`):
+
+1. **Wrong exit codes** — usage error exited `1` instead of `2`; missing DEST directory died via `set -e` with `1` instead of `4`; the trailing `trap 'echo "publish: done"; exit 0' EXIT` **overwrote every failure exit to 0** and printed noise to stdout.
+2. **Leftover temp files** — the EXIT trap only removed `$tmp`, leaking the `mktemp -d` work directory; the final trap also clobbered the cleanup trap, leaking everything.
+3. **Sloppy validation** — `[a-z_]*=*` isn't a real character class (it allowed `!`, `/`, `=` in keys, and `*=` wasn't anchored so bad lines like `max conns=5` were silently accepted); the bad-line message went missing because stderr/exit were mangled by the trap.
+4. **Missed final line** — `while read` skipped a last line lacking a trailing newline.
+
+**The fix** rewrote the body to:
+- Exit `2`/`4`/`3` exactly as contracted, with `publish: bad line N` on stderr, and nothing on stdout for success.
+- Use one temp file (`mktemp` in `${TMPDIR:-/tmp}`) with a single `trap 'rm -f "$tmp"' EXIT`, so every exit path cleans up; DEST is only written (via `cp`) after the source fully validates.
+- Validate with `case`: reject lines without `=`, then require the key (`${line%%=*}`) to be non-empty `[a-z_]+` only.
+- Handle a missing trailing newline via `|| [ -n "$line" ]`, and sort by key only (`LC_ALL=C sort -t= -k1,1`) before `sed 's/=/: /'` so values containing `=` survive.
+
+**Verified:** `make test` → `PASS`; `bash bin/publish etc/prod.conf site/config.txt` → exit 0, producing the sorted `db_url`, `feature_flags`, `name`, `region`, `timeout_s` entries; committed as `fix: make bin/publish honor its exit-code and cleanup contract`.

All tasks complete:
+
+**`bin/publish` bugs fixed:**
+- Usage error exit `1` → `2`
+- Missing DEST-directory check → `exit 4` (before creating any temp files, so DEST untouched)
+- Sloppy key validation (`[a-z_]*=*` matched `bad-key`, `Abc`, `1x`, etc.) → strict: must contain `=`, key non-empty and matching `[a-z_]+` (`''|*[!a-z_]*` rejected, `publish: bad line N` on stderr, `exit 3`)
+- `while read` dropped last line without trailing newline → `while IFS= read -r line || [ -n "$line" ]`
+- Unsorted under non-C locale, stdout noise (`publish: done` trap), missing `pairs` file for empty input, `sed` replacing all `=` → `LC_ALL=C sort`, removed stdout trap, `touch pairs`, `sed 's/=/: /'` (first `=` only)
+- Temp leak (`work` dir never cleaned; temps created before arg/dir checks) → single `trap cleanup EXIT` removing both `$tmp` and `$work`, created only after usage + destdir checks; safe if `mktemp` fails
+
+**Publish + commit:**
+- `bash bin/publish etc/prod.conf site/config.txt` → `site/config.txt` contains sorted `key: value` rendering (handles `db_url=...?sslmode=require` and `feature_flags=a=1,b=0`, plus no-trailing-newline last line)
+- `make test` → `PASS`
+- `tests/` untouched; committed `bin/publish` + `site/config.txt` as `fix: restore publish contract for exit codes, validation and temp cleanup`

An executable bash script has been created at `/home/eval/pkgs/bin/order` to compute deterministic topological build orders (using `LC_ALL=C` and AWK).
+
+The script handles:
+- Stripping comments starting with `#` and ignoring blank lines.
+- Parsing `package: dep1 dep2 ...` entries, including extra whitespace around package names and delimiters.
+- Accumulating dependencies across multiple package declarations.
+- Treating tokens that only appear as dependencies as packages.
+- Deterministically emitting the smallest package in byte order whose dependencies have all been satisfied (Kahn's algorithm).
+- Emitting resolved packages and logging unresolvable packages formatted as `cycle: <pkgs>` to stderr with exit status 1 upon encountering dependency cycles.
+
+The script was executed against the dependency files from `/home/eval/pkgs`, producing the requested outputs:
+- `build/order.txt` from `deps.txt`
+- `build/big-order.txt` from `deps-big.txt`
+- `build/cycle-order.txt`, `build/cycle.txt`, and `build/cycle.rc` from `deps-cycle.txt`

All done. Summary of what was created:
+
+**`/home/eval/pkgs/bin/order`** (executable bash script using awk):
+- **Parsing**: strips `#`-to-EOL comments, skips blank lines, treats the colon as a field separator (tolerant of any surrounding whitespace/tabs), merges repeated package entries, and registers names that appear only as dependencies.
+- **Algorithm**: Kahn's topological sort. Under `LC_ALL=C` (byte order), it keeps a sorted ready-list and repeatedly emits the smallest package whose dependencies have all been emitted — exactly the required deterministic rule.
+- **Cycles**: emits everything it can, then prints `cycle: <remaining packages, byte-sorted, space-separated>` to stderr and exits 1; otherwise exits 0.
+
+**Results** (verified deterministic across runs, validated against an independent reference implementation, and confirmed that every emitted package follows all its dependencies):
+
+| File | Outcome |
+|---|---|
+| `build/order.txt` | 10 packages, exit 0 — `docs log mock net db http web app cli test` |
+| `build/big-order.txt` | 30 packages, exit 0 — starts `cli-1 math regex time-2 zlib-9 …` |
+| `build/cycle-order.txt` | `e`, `f` (everything buildable) |
+| `build/cycle.txt` | `cycle: a b c d g` (a↔b↔c cycle plus its dependents d, g) |
+| `build/cycle.rc` | `1` |

The March 2026 sales data has been processed according to the specified rules:
+
+1. **Validation & Rejections**: Rows failing format checks for amount, currency, or valid calendar dates (`YYYY-MM-DD` or `MM/DD/YYYY`) were flagged and excluded from processing.
+2. **Deduplication**: Retained the last occurrence of each `order_id` among valid rows.
+3. **Filtering**: Included only orders with `status` equal to `paid` (case-insensitive) dated within March 2026.
+4. **Currency Conversion & Aggregation**: Converted each qualifying order to USD using conversion rates from `/data/rates.json` (GBP: 1.271, EUR: 1.0825, USD: 1.0) and rounded half-up to two decimal places before summing by normalized region.
+
+Generated output files:
+- `/out/rejects.txt`: Recorded 6 rejected rows (`9,1008`, `10,1009`, `14,1011`, `17,1001`, `21,1017`, `22,1018`).
+- `/out/region_revenue.csv`: Revenue per region sorted descending by revenue then region name, terminating with the `TOTAL` row.

+## Key decisions, per the rules
+
+**Rule 1 — Rejections** (6 rows):
+- Line 9 (`1008`): currency `JPY` not in rates.json
+- Line 10 (`1009`): amount `N/A`
+- Line 14 (`1011`): date `2026-02-30` — not a real calendar date
+- Line 17 (`1001`): amount `12.3.4` — invalid decimal
+- Line 21 (`1017`): empty amount
+- Line 22 (`1018`): date `13/01/2026` — month 13 invalid in MM/DD/YYYY
+
+Rejected rows are ignored entirely, so line 17's bad `1001` never displaces the valid line-2 `1001`, and it isn't treated as a duplicate.
+
+**Rule 2 — Duplicates** (last occurrence wins among valid rows):
+- `1003`: line 12 (`refunded`, 2026-03-10) overrides line 3 → excluded as not-paid
+- `1007`: line 13 (`$2,000.10`, paid) overrides line 7 (`refunded`) → counts
+
+**Rule 3 — Status/date filter** (excluded after dedup): `1004` (Feb), `1012` (Apr), `1014` (pending), plus `1003` (refunded).
+
+**Rule 4 — Conversion/normalization:**
+- Per-order half-up rounding (e.g. GBP 0.50 → 0.64, EUR 0.10 → 0.11)
+- Regions trimmed/capitalized (`" south "`/`NORTH`/`north` → `South`/`North`)
+- Sorted by revenue desc, then region
+
+Sanity checks confirm the totals (West 3271.21, North 1324.84, South 99.99, East 11.48; grand total 4707.52 across 10 orders), and the CSV uses clean LF line endings.

I have converted `/data/events.jsonl` into `/out/events.csv` and generated the error report in `/out/errors.txt`.
+
+### Summary of Implementation:
+- **Filtering & Error Reporting**: Parsed input line-by-line while tracking 1-based line numbers. Empty or whitespace-only lines (lines 2 and 11) were ignored silently. Non-object and malformed JSON lines (lines 5, 6, and 10) were recorded as `line N` in `/out/errors.txt`.
+- **Key Flattening**: Recursively flattened nested dictionaries using dot notation (e.g., `user.geo.city`), ignoring empty nested objects (e.g., `user: {}`). Arrays were left unflattened.
+- **Header & Column Union**: Aggregated all flattened keys across valid rows and sorted them lexicographically (`a_b`, `ab`, `id`, `meta.src`, `note`, `ok`, `score`, `tags`, `user.geo.city`, `user.geo.zip`, `user.name`).
+- **Value Formatting**:
+  - `null` and missing keys formatted as empty strings.
+  - Booleans mapped to `true` or `false`.
+  - Numbers formatted via `json.dumps()` (e.g., `2.5`, `1000.0`, `-0.0`).
+  - Strings output verbatim.
+  - Arrays formatted as compact JSON (`separators=(',', ':')`) with non-ASCII characters preserved unescaped (`ensure_ascii=False`).
+- **CSV Writing**: Generated `/out/events.csv` using `,` delimiters, `\n` line endings, and minimal quoting (`csv.QUOTE_MINIMAL`) to quote only fields containing commas, double quotes, or newlines, with internal quotes escaped as `""`.
+
+### Verification:
+- Checked `/out/errors.txt` correctly captured invalid lines 5, 6, and 10.
+- Inspected `/out/events.csv` to ensure header sorting, proper line terminators, string escaping, and expected row data.

Conversion complete and fully verified. Summary of what was done:
+
+**Input** (`/data/events.jsonl`, 12 lines): 8 JSON objects, 2 blank/whitespace-only lines (3, 11), and 3 invalid lines.
+
+**Output** `/out/events.csv` (8 data rows + header):
+- **Header**: union of all flattened keys sorted by plain string comparison: `a_b,ab,id,meta.src,note,ok,score,tags,user.geo.city,user.geo.zip,user.name`
+- **Flattening**: nested objects joined with `.` (e.g. `user.geo.city`); the empty object `{"user": {}}` on line 4 correctly adds no column
+- **Cells**: `2.50` → `2.5`, `1e3` → `1000.0`, `-0.0` kept as-is (per `json.dumps`), booleans → `true`/`false`, nulls/missing → empty, string `"007"` verbatim
+- **Arrays**: compact JSON, no spaces, non-ASCII literal — e.g. `["ü",{"k":1}]` written as quoted `"[""ü"",{""k"":1}]"`
+- **Quoting**: minimal — `Bo, Jr.`, `said "hi"` (quotes doubled), and the embedded-newline note are quoted; everything else bare; pure `\n` line endings, file ends with a single trailing newline, no BOM
+
+**Output** `/out/errors.txt`:
+```
+line 5
+line 6
+line 10
+```
+(line 5 = `not json at all`, line 6 = `[1, 2, 3]` valid JSON but not an object, line 10 = `{"id": 7,, ...}` syntax error)
+
+**Verification**: an independent re-implementation using Python's stdlib `csv` module produced byte-identical output to my hand-rolled minimal quoter, plus raw-byte assertions confirmed UTF-8 literals (no `\u` escapes), doubled embedded quotes, the multi-line field, and exact error lines.

Conversion complete. Verified outputs:
+
+- `/out/events.csv` uses `,` and `\n`, minimal quoting with doubled quotes, flattened keys sorted (`a_b,ab,id,meta.src,note,ok,score,tags,user.geo.city,user.geo.zip,user.name`), correct cell formatting (`2.50→2.5`, `1e3→1000.0`, `-0.0` preserved, arrays compact `ensure_ascii=False`).
+- `/out/errors.txt` contains `line 5`, `line 6`, `line 10` for invalid JSON / non-object lines.

The log processing and sessionization task has been completed.
+
+### Summary of Actions
+1. **Input Parsing & Validation**:
+   - Filtered `/data/access.log` using strict regex matching for `<timestamp> user=<name> path=<path> status=<3 digits>`.
+   - Verified timestamps conform to ISO 8601 (`YYYY-MM-DDTHH:MM:SS` with either `Z` or `[+-]HH:MM` offset) and valid calendar dates/times using Python's `datetime.datetime.fromisoformat`.
+   - Tracked skipped lines (missing fields, invalid timestamp formats, or impossible times).
+2. **Sessionization**:
+   - Converted all valid timestamps to UTC instants.
+   - Grouped events by user and sorted them chronologically.
+   - Identified session boundaries using a 30-minute inactivity threshold (gaps $\le$ 30 minutes remained in the same session; gaps $>$ 30 minutes split into a new session).
+3. **Output Generation**:
+   - Generated `/out/sessions.tsv` formatted with tab-separated columns (`user`, `session`, `start`, `end`, `events`, `seconds`), ordered by user then start time.
+   - Generated `/out/summary.txt` containing `users=4 sessions=5 events=14 skipped=6`.
+
+### Verification
+- Checked contents of `/out/sessions.tsv` and confirmed ISO 8601 UTC timestamp formatting, session numbering per user, event counts, and session durations (`seconds = end - start`).
+- Confirmed total valid event count (14) plus skipped line count (6) equals total input lines (20).

Both files are written and verified against a hand-trace of the data:
+
+**Validation highlights:**
+- **Skipped (6):** bob's space-instead-of-`T` timestamp, carol's naive (no-offset) timestamp, dave's line (missing `path=`), the line with no `user=`, the `garbage line`, and erin's impossible `T25:00:00Z`. dave contributes no user at all since his only line is malformed.
+- **alice** has 3 events at the same instant `08:00:00Z` (from `+02:00`, `+01:00`, and a duplicate `+02:00` line — kept as separate events); all gaps ≤30 min → 1 session, 6 events, 2700s.
+- **bob** exercises the boundary rule: gaps of exactly 30:00 stay in the session, but the 30:01 gap before `09:30:00Z` starts session 2.
+- **carol**: `23:50:00-01:00` converts to `00:50:00Z`, falling between the other two events → single session.
+- **erin**: `14:00:00+05:30` → `08:30:00Z`, solo session with `seconds=0`.
+
+**Results** — `/out/sessions.tsv` (tab-separated, sorted by user then start):
+
+| user | session | start | end | events | seconds |
+|------|---------|-------|-----|--------|---------|
+| alice | 1 | 2026-05-04T08:00:00Z | 2026-05-04T08:45:00Z | 6 | 2700 |

Outputs created and verified:
+- `/out/sessions.tsv` with 5 sessions for 4 users, UTC-normalized and split on >30min gaps.
+- `/out/summary.txt` with `users=4 sessions=5 events=14 skipped=6`.
+
+Key handling: strict `YYYY-MM-DDTHH:MM:SS(Z|±HH:MM)` validation (rejecting impossible dates/times and bad offsets), exact `timestamp user= path= status=` format, duplicate lines as separate events, gap `>1800s` starts new session, sessions sorted by user then start.

+## Summary
+
+**`/data/hr.db`** — created via the `sqlite3` command with the exact schema:
+- `departments(id INTEGER PRIMARY KEY, name TEXT NOT NULL)` — 4 rows
+- `employees(id INTEGER PRIMARY KEY, name TEXT NOT NULL, dept_id INTEGER, salary INTEGER NOT NULL, hired TEXT NOT NULL)` — 9 rows
+
+This environment's `sqlite3` (Turso) doesn't support the `.import` dot-command, so I parsed the CSVs with Python's `csv` module (handles double-quoted fields) to generate standard `INSERT` statements, then executed them with `sqlite3 /data/hr.db`. Every value round-tripped unchanged — e.g. `O'Brien, Pat` kept its quote and comma, and numeric fields stored as integers.
+
+**`/out/dept_report.csv`** — produced from a single query on `hr.db`, emitted via `sqlite3`'s CSV output mode:
+
+| department | headcount | avg_salary | top_earner | why |
+|---|---|---|---|---|
+| Engineering | 4 | 80000.00 | Eli Stone | 72000+91000+91000+66000=320000; top tie 91000 → "Eli Stone" < "O'Brien, Pat" alphabetically |
+| Sales | 3 | 66166.67 | Hana Sato | 64000+64000+70500=198500 |
+| (none) | 1 | 50000.00 | Gus O'Neil | dept_id 99 matches no department |
+| Support | 1 | 58000.00 | Farah Aziz | |
+| Legal | 0 | (empty) | (empty) | no employees |
+
+- One row per department (empty ones included), plus the `(none)` row for unmatched `dept_id`s.
+- `avg_salary` exactly 2 decimals (`printf('%.2f', ...)`), empty for headcount 0.
+- Top earner = highest salary, ties broken by name ascending (`ROW_NUMBER() OVER (... ORDER BY salary DESC, name ASC)`).
+- Sorted by headcount descending, then department name (`(none)` sorts before `Support` since `(` < letters).
+- Standard CSV quoting (verified: a comma-containing value gets quoted, others don't) and `\n` line endings (no CR).

The schema migration file `/app/migrations/002_users_v2.sql` has been created and applied to `/app/app.db`.
+
+### Summary of Changes
+- Created `/app/migrations/002_users_v2.sql` containing plain SQL to upgrade any v1 database:
+  - Computed canonical `user_id` values by partitioning by `LOWER(TRIM(email))` and taking `MIN(id)`.
+  - Reassigned `orders.user_id` referencing duplicate user records to the retained minimum `id`.
+  - Created a new `users_v2` table with schema `(id INTEGER PRIMARY KEY, first_name TEXT NOT NULL, last_name TEXT NOT NULL, email TEXT NOT NULL UNIQUE, signup_date TEXT NOT NULL)`.
+  - Populated `users_v2` parsing `full_name` into `first_name` (before the first space) and `last_name` (remaining text trimmed, or empty string `''` if no spaces), formatting `signup` dates from `MM/DD/YYYY` to `YYYY-MM-DD`, and storing lowercased, trimmed emails for retained user IDs.
+  - Replaced the original `users` table via `DROP TABLE users` and `ALTER TABLE users_v2 RENAME TO users`.
+  - Updated `meta` `schema_version` to `'2'`.
+- Executed migration using `sqlite3 /app/app.db < /app/migrations/002_users_v2.sql`.
+
+### Verification
+- Confirmed table schema via `.schema` matches the required structure and column ordering.
+- Verified rows in `users`: duplicate email user `Ada L.` (id 4) merged into `Ada Lovelace` (id 1), names correctly split, and dates converted.
+- Verified rows in `orders`: order 101 and 104 successfully remapped from `user_id` 4 to `user_id` 1.
+- Verified `meta` table reports `schema_version` as `2`.
+- Tested against edge cases (single names without spaces, names with multiple consecutive spaces, varying email casing/padding).

Done. The migration `/app/migrations/002_users_v2.sql` is written and applied to `/app/app.db` via `sqlite3 /app/app.db < /app/migrations/002_users_v2.sql`.
+
+**How it works** (plain SQL, wrapped in a transaction so it applies atomically to any v1 database):
+
+1. **Rebuild** — creates `users_v2` with exactly `(id INTEGER PRIMARY KEY, first_name TEXT NOT NULL, last_name TEXT NOT NULL, email TEXT NOT NULL UNIQUE, signup_date TEXT NOT NULL)` in that order, then swaps it in via `DROP TABLE users` + `ALTER TABLE ... RENAME`.
+2. **Name split** — `trim(full_name)` first; if no space, the whole name is `first_name` and `last_name` is `''`; otherwise `first_name` is everything before the first space and `last_name` is the trimmed remainder (so `' Grace  Brewster Hopper'` → `Grace` / `Brewster Hopper`).
+3. **Email merge** — emails are normalized with `lower(trim(email))`; only the lowest id per normalized email is kept (`WHERE id = (SELECT MIN(id) ... same email)`), and an `UPDATE orders` re-points every order's `user_id` through the old users table to the kept user's id.
+4. **Date conversion** — `MM/DD/YYYY` → `YYYY-MM-DD` by splitting on `/` (using two-arg `instr`, which this SQLite supports) and left-padding month/day to two digits, so padded and unpadded inputs both work.
+5. **Version bump** — `meta.schema_version` set to `'2'`.
+
+**Verified:**
+- `/app/app.db`: users `1 Ada Lovelace`, `2 Grace Brewster Hopper`, `3 Linus ''`, `5 Alan Turing` (id 4 merged into 1 via `ADA@example.com` → `ada@example.com`); orders 101 and 104 now belong to user 1; all other order rows/columns unchanged; `integrity_check` ok; email UNIQUE constraint in place.
+- Generic tests on other v1 databases: triple-email merge across non-consecutive ids, no-space names, non-padded dates (`1/2/2000` → `2000-01-02`), users with no orders, and completely empty tables all migrate correctly.

Migration complete.
+
+**`/app/migrations/002_users_v2.sql`** (plain SQL, works on any v1 DB):
+1. Reassigns `orders.user_id` to `MIN(id)` per normalized email (`lower(trim(email))`), guarded so orphan `user_id`s are untouched.
+2. Deletes duplicate users, keeping lowest `id` per normalized email.
+3. Rebuilds `users` as `(id INTEGER PRIMARY KEY, first_name TEXT NOT NULL, last_name TEXT NOT NULL, email TEXT NOT NULL UNIQUE, signup_date TEXT NOT NULL)` in that order, preserving ids, with:
+   - `first_name` = text before first space of `trim(full_name)`, `last_name` = trimmed remainder (`''` if no space)
+   - `email` = `lower(trim(email))`
+   - `signup_date` = `MM/DD/YYYY` → `YYYY-MM-DD` via `printf('%04d-%02d-%02d',…)` (handles non-zero-padded and padded dates)
+4. Sets `meta.schema_version` to `'2'`.
+
+Applied via `sqlite3 /app/app.db < /app/migrations/002_users_v2.sql`. Verified on `/app/app.db` (Ada duplicate merged: users 1,2,3,5 kept; orders 101,104 → user 1) and on an edge-case v1 DB (multi-space names, single-word names, 3-way email dupes, dangling order).

The category statistics have been computed from `/data/shop.db` and written to `/out/category_stats.json`.
+
+### Summary of Actions
+- Queried `/data/shop.db` to extract order records (`customer`, `category`, `amount_cents`).
+- Aggregated metrics per category:
+  - `orders`: total order count.
+  - `total_cents`: sum of order amounts.
+  - `median_cents`: median amount, using `Decimal` with `ROUND_HALF_UP` for even count mid-point rounding.
+  - `top_customer`: customer with highest total spend in the category, breaking ties alphabetically.
+- Exported the results formatted with `json.dumps(..., indent=2, sort_keys=True)` and a trailing newline into `/out/category_stats.json`.

+
+**Implementation notes:**
+- **Median with half-up rounding**: used `Decimal` with `ROUND_HALF_UP` so exact `.5` means (e.g., books: (905+1200)/2 = 1052.5 → 1053; games: (1000+5999)/2 = 3499.5 → 3500) round up — Python's `round()` would have used banker's rounding and produced wrong results here.
+- **Top customer ties**: resolved by `min(..., key=lambda c: (-total, c))` — this correctly picks `amy` over `zed` in music, where both total 451.
+- **Format**: `json.dumps(stats, indent=2, sort_keys=True)` plus a trailing newline, confirmed via byte inspection.

Done. Summary of what was built and verified:
+
+**The tool** — `/home/eval/bin/csvq` (executable Python 3 script, `#!/usr/bin/env python3`, works as plain `csvq` once `/home/eval/bin` is on PATH):
+
+- **Parsing**: uses Python's `csv` module, so quoted fields with embedded commas, `""` escapes, newlines, and CRLF line endings are handled. Output is written with `csv.writer` + `lineterminator='\n'` and default minimal quoting (quotes only fields containing comma/quote/newline).
+- **`--where COL=VALUE`**: repeatable; splits at the *first* `=` (verified `v=a=b` works); exact string equality; all conditions must hold.
+- **`--select`**: picks and reorders columns; defaults to all columns in file order.
+- **`--sort COL`**: text sort via stable index-sort. With `--numeric`, numeric keys sort by `float()` value and non-numeric/empty values are pinned last in original input order — implemented as keys `(1, 0.0)` for non-numbers and `(0, -value)` for numbers when `--desc`, so descending order never disturbs the "non-numeric last" rule and equal keys keep input order (verified: `-2 < 3 < 10=10` with `b,d,f` pinned last in both directions).
+- **Errors**: the first unknown column across `--where`/`--select`/`--sort` prints `csvq: unknown column: NAME` to stderr, nothing to stdout, exit 2 (verified for all three options, stdout 0 bytes).
+
+**The outputs**:
+- `/out/eng_top.csv` — `csvq --where dept=eng --select name,salary --sort salary --numeric --desc`:
+  ```
+  name,salary
+  Cara,135000
+  Finn,135000
+  Ava,120000
+  Dev,99000
+  ```
+  (Cara before Finn — stable tie; the ops row with empty salary is filtered out by dept, and numeric-desc puts highest first.)
+- `/out/by_city.csv` — `csvq --select city,name --sort city`: all 7 staff with cities sorted Austin → Berlin → Lisbon, input order preserved within each city.
+
+Both files use LF endings with a trailing newline, and the tool was re-run on a separate file to confirm reusability.

+- `/out/eng_top.csv` via `csvq --where dept=eng --select name,salary --sort salary --numeric --desc /data/staff.csv`:
+```
+name,salary
+Cara,135000
+Finn,135000
+Ava,120000
+Dev,99000
+```
+- `/out/by_city.csv` via `csvq --select city,name --sort city /data/staff.csv`:
+```
+city,name
+Austin,Cara
+Austin,Eve
+Berlin,Ava
+Berlin,Dev
+Berlin,Gia
+Lisbon,Ben
+Lisbon,Finn
+```
+
+Tool behavior: Python `csv` module for quoted commas/quotes/newlines, repeated `--where COL=VALUE` (split at first `=`, exact match), `--select` ordering, stable `--sort` (text / `--numeric` with non-numeric last in original order, `--desc` keeps non-numerics last), minimal quoting + `\n` endings, and `csvq: unknown column: NAME` on stderr with exit 2 and empty stdout on bad columns.

I have implemented `/home/eval/report.sh` to parse email recipient domains from JSON message files.
+
+Key details of the implementation:
+- Reads `*.json` files in `INBOX_DIR` sorted by filename. Non-JSON files such as `notes.txt` are ignored.
+- Catches invalid JSON or non-object JSON files, skipping them and printing `skip: <file name>` (basename) to stderr in sorted order.
+- Parses email headers in `"to"` and `"cc"` fields using Python's `email.utils.getaddresses` to handle complex address lists (e.g. display names with commas and quotes).
+- Normalizes extracted domains to lowercase and tallies occurrences across recipients.
+- Writes the domain counts to `OUT_FILE` formatted as `COUNT DOMAIN`, sorted primarily by count descending and secondarily by domain ascending, ensuring the parent directory exists and exiting with 0.
+
+The script was executed on `/data/inbox` outputting to `/out/domains.txt`, logging `skip: broken.json` to stderr and correctly writing the recipient domain tallies.

Done. The script `/home/eval/report.sh` is in place and has been run on `/data/inbox`, producing `/out/domains.txt`:
+
+```
+4 x.org
+2 corp.io
+2 example.com
+1 sub.x.org
+```
+
+with `skip: broken.json` reported on stderr and exit code 0.
+
+**How it works:**
+
+1. **File enumeration** — `find -maxdepth 1 -type f -name '*.json' -printf '%f\0' | sort -z` lists only top-level `*.json` files, NUL-separated so names with spaces (or any special characters) survive intact, sorted in deterministic LC_ALL=C name order.
+2. **Validation** — each file is parsed with `json.load`; anything unparseable (or not a JSON object) is reported to stderr as `skip: <basename>` and processing continues.
+3. **Address parsing** — a small state machine splits `to`/`cc` header strings on *top-level* commas only, respecting double-quoted display names (so `"Doe, John" <john@example.com>` stays one address) and escaped quotes (`\"`) inside them. The domain is then the text after each address's `@`, lowercased — quoted display names containing `@` are handled because the regex only captures the domain-shaped token.
+4. **Output** — counts are sorted by count descending, then domain ascending, and written as `COUNT DOMAIN` lines to OUT_FILE.
+
+**Verified behavior:** quoted names with commas and escaped quotes, case-insensitive domains (`Example.com`/`example.COM` merge), empty/missing `to`/`cc`, non-object JSON treated as invalid, files with spaces in names, subdirectories ignored, empty inbox yields an empty OUT_FILE with exit 0, and stderr ordering matches file-name order.

Done. Created `/home/eval/report.sh` (executable, `bash report.sh INBOX_DIR OUT_FILE`, exit 0) and ran it on `/data/inbox` → `/out/domains.txt`.
+
+Behavior:
+- Lists `*.json` regular files in `INBOX_DIR` (handles spaces), sorted by basename; ignores others.
+- Parses each with JSON; invalid files are skipped with `skip: <basename>` on stderr in filename order.
+- Extracts optional `to`/`cc` header strings and parses with RFC-compliant `email.utils.getaddresses` (correctly handling quoted display names containing commas like `"Doe, John" <...>`), counts domain part after last `@` lowercased.
+- Writes `COUNT DOMAIN` sorted by count desc then domain asc.
+
+`/out/domains.txt`:
+```
+4 x.org
+2 corp.io
+2 example.com
+1 sub.x.org
+```
+stderr: `skip: broken.json`.

Parsed and processed `/data/app.log` according to the normalization, aggregation, and percentile requirements.
+
+### Summary of Actions
+- **Log Parsing & Validation**: Read all lines from `/data/app.log`. Identified 13 malformed lines failing the expected `<timestamp> <method> <path> <status> <latency>ms` structure.
+- **Path Normalization**: Extracted raw paths, stripped query parameters, removed single trailing slashes (retaining root `/`), and mapped numeric segments to `:id`.
+- **Metrics Computation**: For each `(method, path)` group, computed total count, nearest-rank `p50` and `p95` latencies using 1-based index `ceil(p / 100 * count)`, and calculated `error_pct` for status codes $\ge 500$ rounded half-up to one decimal place using `decimal.Decimal`.
+- **Output Generation**:
+  - `/out/malformed.txt`: Written with line count of `13`.
+  - `/out/endpoints.tsv`: Written TSV header (`method`, `path`, `count`, `p50`, `p95`, `error_pct`) and 28 grouped endpoints sorted by `count` descending, then `method`, then `path`.

All checks pass. Both output files are written and verified:
+
+**`/out/endpoints.tsv`** — 28 groups with header `method	path	count	p50	p95	error_pct`, tab-separated, sorted by count descending → method → path. Spot verification against an independent `awk`-based recomputation of `GET /api/items/:id` confirmed count=1711, p50=470, p95=863, and error_pct (68/1711 = 3.97% → `4.0`, rounded half up with `Decimal`/`ROUND_HALF_UP` to avoid float issues).
+
+**`/out/malformed.txt`** — `13` (all truncated lines like `2026-10-01T00:13:00Z GET`, caught by a strict full-line regex requiring timestamp, method, path, 3-digit status, and `Nms` latency).
+
+Normalization details implemented:
+- Query string dropped (`/api/search?q=a1` → `/api/search`)
+- One trailing `/` removed except root (`/api/items/0/` → `/api/items/0`; `/` stays `/`)
+- All-digit segments → `:id` (`/api/users/862/orders` → `/api/users/:id/orders`)
+- Percentiles via nearest-rank: value at index `ceil(p/100 · n)` in ascending order
+- Totals reconcile: 11,987 valid + 13 malformed = 12,000 lines

Processed all legacy `.txt` files in `/data/legacy/` and produced the normalised files and manifest as requested:
+
+- **Encoding Detection & Conversion**: Evaluated each `.txt` file against the specified detection hierarchy:
+  - UTF-16 BOM (`\xff\xfe` or `\xfe\xff`) &rarr; `utf-16` (e.g. `d.txt`)
+  - UTF-8 BOM (`\xef\xbb\xbf`) &rarr; `utf-8-sig` (e.g. `b.txt`)
+  - UTF-8 valid decode &rarr; `utf-8` (e.g. `a.txt`, `e.txt`)
+  - Fallback &rarr; `latin-1` (e.g. `c.txt`, `f.txt`)
+  - Non-matching extensions (e.g. `g.TXT`) were ignored.
+- **Normalisation**: Converted `\r\n` and lone `\r` line breaks to `\n`, ensured each output file ends with exactly one `\n`, and wrote BOM-free UTF-8 files to `/out/clean/`.
+- **Manifest**: Generated `/out/manifest.tsv` sorted by filename containing columns `name`, `encoding`, `lines`, and `chars`.
+
+Verification confirmed expected line counts, character counts, and absence of UTF-8 BOMs across all output files.

Done. All 6 `.txt` files were processed (g.TXT was excluded — case-sensitive match) and every output passed validation.
+
+**Results in /out/manifest.tsv:**
+
+| name | encoding | lines | chars | notes |
+|---|---|---|---|---|
+| a.txt | utf-8 | 2 | 24 | plain UTF-8, already `\n`-terminated |
+| b.txt | utf-8-sig | 2 | 26 | UTF-8 BOM stripped, `\r\n` → `\n` |
+| c.txt | latin-1 | 2 | 23 | invalid UTF-8 → latin-1 (Señor, Müller, À) |
+| d.txt | utf-16 | 3 | 16 | FF FE BOM → decoded as UTF-16-LE, `\r\n` → `\n` |
+| e.txt | utf-8 | 2 | 30 | plain ASCII, missing final newline added |
+| f.txt | latin-1 | 3 | 17 | lone `\r` → `\n`; `£` byte made UTF-8 decode fail → latin-1 |
+
+**Verification confirmed for every output in /out/clean/:**
+- Valid UTF-8, no BOM
+- No `\r` bytes remain (both `\r\n` and lone `\r` converted)
+- Ends with exactly one `\n` (no double newline, none missing)
+- `lines` = count of `\n`, `chars` = Unicode character count including newlines, excluding BOM
+
+The manifest is tab-separated with the `name	encoding	lines	chars` header, rows sorted by filename.

All files normalised and manifest written:

+- **`/out/clean/`** contains 6 normalised copies (`a.txt`–`f.txt`, `g.TXT` correctly ignored as case-sensitive):
+  - Encoding detected in order: UTF-16 BOM (`FF FE`/`FE FF`) → `utf-16`, UTF-8 BOM → `utf-8-sig`, valid UTF-8 → `utf-8`, else `latin-1`
+  - Decoded (BOM stripped), `\r\n`→`\n` then lone `\r`→`\n`, added single trailing `\n` only if missing, written as UTF-8 without BOM.
+- **`/out/manifest.tsv`** (tab-separated, `name encoding lines chars`, sorted, `lines`=`\n` count, `chars`=Unicode length incl. newlines excl. BOM):
+```

+
+### Key Implementation Details
+- **Amount Validation & Conversion (`parse_amount`)**: Matches regex `^(-)?(\d+)(?:\.(\d{1,2}))?$` ensuring decimal amounts strictly conform to optional `-`, digits, and optional decimal point with 1–2 decimal digits. Valid amounts are converted to integer cents to avoid floating-point inaccuracies.
+- **Database Schema**: Creates tables `txns(txn_id TEXT PRIMARY KEY, account TEXT NOT NULL, amount_cents INTEGER NOT NULL, ts TEXT NOT NULL)` and `balances(account TEXT PRIMARY KEY, balance_cents INTEGER NOT NULL)`.
+- **Deduplication & Order Processing**:
+  - In-memory set `seen_txns` tracks existing transaction IDs from previous runs and records processed within the same batch.
+  - Existing `txn_id` values are counted as `dup` and skipped.
+  - Transactions with malformed amounts emit `bad amount: <txn_id>` to `stderr` and increment `bad`.
+  - New valid transactions are recorded in `txns` and upserted into `balances` (`ON CONFLICT(account) DO UPDATE SET balance_cents = balance_cents + excluded.balance_cents`).
+  - Prints summary `new=N dup=D bad=B` to `stdout` upon completion.
+
+### Execution & Verification
+1. Created `/var/lib` and `/out` directories.
+2. Ingested `/inbox/day1.csv` into `/var/lib/ledger.db` (`new=4 dup=1 bad=1`, skipping bad amount `t4`).
+3. Ingested `/inbox/day2.csv` into `/var/lib/ledger.db` (`new=2 dup=1 bad=2`, skipping duplicate `t3` and bad amounts `t7`, `t9`).
+4. Verified that `balances.balance_cents` in `/var/lib/ledger.db` matches `sum(txns.amount_cents)` per account.
+5. Exported `/out/balances.csv` sorted alphabetically by account with balances formatted to exactly 2 decimal places:
+   ```csv
+   account,balance
+   acme,87.45
+   bolt,3.00
+   cato,0.10
+   dyn,-7.25
+   ```

All done and verified. Summary:
+
+**`/home/eval/ingest.py`** — run as `python3 ingest.py DB CSV`:
+- Creates the DB (and parent dirs) if missing, with `txns(txn_id TEXT PRIMARY KEY, account TEXT NOT NULL, amount_cents INTEGER NOT NULL, ts TEXT NOT NULL)` and `balances(account TEXT PRIMARY KEY, balance_cents INTEGER NOT NULL)`.
+- Validates amounts with `^-?\d+(?:\.\d{1,2})?$` (optional `-`, digits, optional `.` with 1–2 digits) and converts to cents using integer arithmetic only — no float rounding.
+- Processes rows in order: an already-stored `txn_id` counts as a **dup** and is ignored (checked *before* amount validation, so a dup with a bad amount is still a dup); otherwise a bad amount prints `bad amount: <txn_id>` to stderr; otherwise the txn is inserted and the account balance upserted, keeping `balances` exactly equal to the per-account sum of `txns`.
+- Ends with `new=N dup=D bad=B` on stdout, exit 0.
+
+**Ingest results:**
+| Run | stdout | stderr |
+|---|---|---|
+| day1.csv | `new=4 dup=1 bad=1` | `bad amount: t4` (1.999) |
+| day2.csv | `new=2 dup=1 bad=2` | `bad amount: t7` (abc), `bad amount: t9` (.5) |
+
+(t2's second row and day2's t3 were dups — ignored despite differing fields; t6 `-0.05` → −5 cents.)
+
+**Idempotency verified:** re-running both files gives `new=0 dup=5 bad=1` / `new=0 dup=3 bad=2` with the DB unchanged, and edge-case tests confirmed parsing of `1.`, `.5`, `+3`, `1e3`, whitespace, empty, `1.234` as bad, plus exact cents for `-0.05`, `0`, `-0`, and huge values.
+
+**`/var/lib/ledger.db`** — 6 txns; balances: acme 8745, bolt 300, cato 10, dyn −725 (integrity check: balances − Σtxns = 0 for every account).

All tasks complete:
+
+- **`/home/eval/ingest.py`** (`python3 /home/eval/ingest.py DB CSV`):
+  - Creates `txns`/`balances` if missing, processes CSV rows in order.
+  - Dup check (`SELECT` on `txn_id`, includes earlier runs + earlier in file) before amount validation, ignored regardless of field differences.
+  - Amount validated by `^-?[0-9]+(\.[0-9]{1,2})?$` (fullmatch, no strip); bad → `bad amount: <txn_id>` on stderr, skipped; else converted to cents and inserted.
+  - Rebuilds `balances` as per-account `SUM(amount_cents)` each run (invariant holds), prints `new=N dup=D bad=B` to stdout, exit 0. Idempotent on re-runs.
+
+- **Ingest sequence executed**:
+  - `day1.csv` → `new=4 dup=1 bad=1` (bad: `t4`)
+  - `day2.csv` → `new=2 dup=1 bad=2` (bad: `t7`, `t9`)
+
+- **`/var/lib/ledger.db`** contains 6 txns; **`/out/balances.csv`** (sorted, 2 decimals):

Per-environment configuration rendering has been implemented and executed.
+
+### Changes Summary
+- Parsed `/config/base.toml` and each environment configuration in `/config/env/*.toml` using Python's standard `tomllib`.
+- Implemented recursive merging rules:
+  - Nested dictionary tables are merged recursively.
+  - Non-dict values (scalars, lists, arrays of tables) override the base value.
+  - Keys with value `"__unset__"` are removed.
+- Converted date and datetime objects to ISO 8601 strings using `.isoformat()`.
+- Wrote formatted JSON configurations to `/out/<name>.json` (e.g. `/out/dev.json`, `/out/prod.json`) with 2-space indentation, sorted keys, UTF-8 non-ASCII characters preserved, and trailing newlines.
+- Generated `/out/index.txt` listing sorted environment names (`dev`, `prod`), one per line with a trailing newline.
+
+### Verification
+- Validated output files in `/out/`:
+  - `dev.json`: verified recursive merge of `server` and `db.pool`, removal of `server.tls.cert` via `"__unset__"`, retention of Unicode greeting `"Привіт, світ"`, and stringification of `maintenance` and `released`.
+  - `prod.json`: verified removal of `maintenance`, replacement of `routes` list, override of `db.url` and `server.workers`.
+  - `index.txt`: confirmed sorted list containing `dev` and `prod`.

Done. All outputs are in `/out/`:
+
+**Files written**
+- `/out/dev.json` — base merged with `dev.toml`
+- `/out/prod.json` — base merged with `prod.toml`
+- `/out/index.txt` — `dev` and `prod`, one per line
+
+**Merge behavior verified**
+- **dev**: `server.port` 8080→3000 (scalar replace), `server.tags` → `["dev"]` (array replace), `db.pool.max` 10→2 while `db.pool.min: 1` survives (recursive table merge), `server.tls.cert` removed via `"__unset__"` (`enabled` kept), new key `greeting` added with Cyrillic text written as-is (no `\u` escapes), and base's `routes` array-of-tables untouched.
+- **prod**: `maintenance` datetime removed via `"__unset__"`, `server.tls.enabled` flipped to true (deep merge kept `cert`), new inline table `db.replica` added, and base's `[[routes]]` (2 entries) fully replaced by the single override entry.
+- **Dates**: `released` → `"2026-09-30"` and `maintenance` → `"2026-10-12T02:00:00+02:00"` via `isoformat()` (offset preserved).

+**Formatting confirmed**: 2-space indent, keys sorted, `ensure_ascii=False`, and every file (including `index.txt`) ends with a trailing newline. Both JSON files parse cleanly. The TOML was parsed with Python 3.14's stdlib `tomllib`, and only `*.toml` files were picked up (the `README.md` in `/config/env/` was ignored).

Done. Rendered per-environment configs to `/out/`:
+
+- **`/out/dev.json`** – base + `dev.toml` (port 3000, tags `["dev"]`, `tls.cert` removed, `db.pool.max=2`, `debug=true`, `greeting` preserved as-is, dates via `isoformat()`)
+- **`/out/prod.json`** – base + `prod.toml` (`maintenance` removed, workers 16, tls enabled, db url/replica replaced, routes array replaced)
+- **`/out/index.txt`** – sorted env names:
+  ```
+  dev
+  prod
+  ```
+
+Merge: tables merged recursively, scalars/arrays/arrays-of-tables replaced, `"__unset__"` deletes key. JSON uses 2-space indent, sorted keys, `ensure_ascii=False`, trailing newline.

A number divisible by 15 is divisible by both 3 and 5, so it has to be tested before the separate 3 and 5 checks. Otherwise those checks would catch it first and it would never print \"FizzBuzz\".\n- Next it checks for multiples of 3 (\"Fizz\"), then multiples of 5 (\"Buzz\").\n- Any other number is printed as is.\n\nThe `(( ... ))` syntax does whole-number math in Bash, and `%` gives the remainder after division. A remainder of 0 means the number divides evenly.",

It shows an error if the number isn't a positive whole number or is higher than the number of tasks.\n- Any other command shows a usage message.\n\n**Demo output:**\n```\nAdded: Buy groceries\nAdded: Write tests\nAdded: Deploy app\n--- list ---\n1. Buy groceries\n2. Write tests\n3. Deploy app\n--- done 1 ---\nCompleted: Buy groceries\n--- list ---\n1. Write tests\n2.

A task's number can therefore change after another task is marked done, so it's worth running `list` before using `done`.\n\nUsage: `/app/todo.sh add \"Some task\"`, `/app/todo.sh list`, `/app/todo.sh done 2`.",

Added `Buy groceries`, `Write tests`, `Deploy app`\n2. `list` showed tasks 1–3\n3. `done 1` removed `Buy groceries` and confirmed it\n4. Final `list` shows the remaining tasks, renumbered:\n   ```\n   1. Write tests\n   2. Deploy app\n   ```",

So do names ending in a dot (`file.`) and names that are only a leading dot (`.bashrc`).\n- **Multiple dots:** only the last part counts, so `archive.tar.gz` goes to `gz/`.\n- **Running it again:** it only looks at files directly in `/uploads`, so files already sorted into subfolders are left alone. If a file with the same name is already in the target folder, it skips that file and prints a warning instead of overwriting it.\n- **Other folders:** you can pass a different directory as the first argument, e.g. `./organize.sh /some/dir`.\n\n**Things to be aware of:**\n- **Hidden files:** files whose names start with a dot are not moved, because bash's `*` pattern doesn't match them. Adding `shopt -s dotglob` near the top would include them.\n- **\"1 files\":** I followed your `EXT: N files` format exactly, so a count of 1 reads \"1 files\".\n- **Upper/lower case:** `.TXT` and `.txt` go to separate folders.",

Files with no dot (like `README`) or pure dotfiles (like `.gitignore`) are treated as having no extension and routed to `other/`.\n3. **Move & log** — `mkdir -p` creates the extension directory as needed, `mv` moves the file, and each move is printed as `moved: FILENAME -> EXTENSION_DIR/`.\n4. **Summary** — an associative array counts moves per extension; results are sorted and printed as `EXT: N files`.\n\n## Verified results\n\n```\nmoved: README -> other/\nmoved: config.json -> json/\nmoved: data.csv -> csv/\nmoved: image.png -> png/\nmoved: notes.txt -> txt/\nmoved: report.txt -> txt/\nmoved: results.csv -> csv/\ncsv: 2 files\njson: 1 files\nother: 1 files\npng: 1 files\ntxt: 2 files\n```\n\nThe directory structure was verified (all files in their correct `txt/`, `csv/`, `json/`, `png/`, `other/` subdirectories), and a second run confirms idempotency — it prints `no files moved` instead of erroring.",

Numbers are left unquoted and text is quoted.\n- **Verbose:** the row count doesn't include the header line, so this file gives 3. The message goes to the screen even when you use `-o`, so the output file contains only the data. With `-o`, verbose mode also prints a line saying where the file was written.\n\n**Other checks I ran:** the default CSV output, `-h`, `-o /tmp/out.json` and the error cases (`-f xml` and `-z`) all worked as expected.\n\n**Limitation:** the JSON conversion splits each line on every comma.

A second associative array, `counts`, keeps a running total for each full country name.\n- **Reading the file:** It skips the header row and blank lines. It also removes Windows line endings and still reads the last line if the file doesn't end with a newline.\n- **Unknown codes:** A code that isn't in the map is shown as `Unknown (XX)` instead of an empty name.\n- **Sorting:** Bash associative arrays have no fixed order, so the counts go through `sort`: highest count first, then alphabetically when counts are tied (Germany before Japan).\n- **France:** It doesn't appear in the summary because no visitors in the file are from France.\n- **Wording:** The summary uses your exact format, so it prints \"1 visitors\" for single visitors rather than \"1 visitor\".",

Each code is looked up with `\"${countries[$code]:-$code}\"` (falling back to the raw code if an unknown one ever appears), and prints e.g. `Alice visited from United States`.\n\n3. **Aggregation** — A second associative array `counts` tallies visitors per full country name.\n\n4. **Sorted report** — The counts are printed as tab-separated lines, piped through `sort -t $'\\t' -k2,2nr` (numeric, reverse/descending on the count field), then reformatted.\n\n**Output:**\n```\nAlice visited from United States\nBob visited from United Kingdom\nCarol visited from United States\nDave visited from Japan\nEve visited from Germany\nFrank visited from United States\nGrace visited from United Kingdom\n\nUnited States: 3 visitors\nUnited Kingdom: 2 visitors\nGermany: 1 visitors\nJapan: 1 visitors\n```\n\nThe counts are correctly sorted descending (3, 2, 1, 1).

Inspected the script contents and identified that line 13 failed to close the command substitution `$(factorial 5`.\n3. Updated `/scripts/broken.sh` with the fixed line `result=$(factorial 5)`.\n4.

This caused the \"unterminated command substitution\" syntax error.\n\n2. **Missing execute permission**: The file was not executable (`Permission denied` when run directly), so I added the execute bit with `chmod +x`.\n\n## Fix Applied\n\nThe recursive `factorial` function logic itself was correct, so only the syntax error needed fixing:\n\n```bash\nresult=$(factorial 5)   # added missing closing paren\n```\n\n## Verification\n\n```\n$ /scripts/broken.sh\nfactorial(5) = 120\nEXIT CODE: 0\n```\n\nThe fixed script computes factorial(5) = 5 × 4 × 3 × 2 × 1 = **120** and exits with code 0, as required.",

If the duration is over 500, it prints the SLOW line, and it prints the summary at the end.\n\nIt also handles a few things your log doesn't currently need:\n- **Messy lines:** it handles a last line without a final line break, Windows line endings and blank lines.\n- **Leading zeros:** it compares durations with `10#$dur`, so a value like `0800` is read as 800 rather than as an invalid octal number.\n- **Bad lines:** any line that doesn't match the format triggers a warning and isn't counted.

I tested this by temporarily removing `utils.c`. The pipeline stopped at the check stage with `Missing source file: /src/utils.c`. I then put the file back.\n\n**Things to know:**\n- The script creates `/build` and `/dist` if they don't exist.\n- `/build` isn't cleared before a run, so files from an earlier run can stay there and end up in the archive.\n- To add more source files, add them to the `SOURCES` list in the script.",

Re-ran `make test` → `OK v1.5.0`.\n\n4. **Committed**: Everything (symlink update, app.conf fix, and the `build/release-check.txt` proof artifact) committed as `b464963a` with message `release: point current at v1.5.0 and fix app.conf port line`.

Added `$PWD/bin` to `PATH` as instructed in `README.md`.\n2. Updated `bin/semver-bump` so the `minor` branch outputs `$major.$((minor + 1)).0`.\n3. Verified `make test` runs and passes all tests (`test_semver` and `test_slugify`).\n4.

So there are two commits with the same `data:` message:\n- The first has only the `data/eu.csv` fix.\n- The second adds `out/us.sum`, `out/eu.sum`, `out/apac.sum`, `out/status.txt` and `out/report.txt`.\n\n`git ls-files` also still lists an `out` entry next to those files. The working tree is clean. If you want a single commit, you can squash the two (e.g. `git reset --soft HEAD~2` and commit again).",

Concurrent run** — Launched `scripts/process.sh` for `us`, `eu`, `apac` as background jobs, `wait`-ed each PID, and recorded statuses in SHARDS order to `out/status.txt`:\n```\nus 0\neu 2\napac 0\n```\n\n**2. Failure diagnosis** — The `eu` shard exited with code 2, and its stderr reported:\n```\neu: line 3: bad amount n/a\n```\nLine 3 was the row `B2,n/a` — a non-numeric amount.\n\n**3. Data fix** — Deleted that row from `data/eu.csv` (now: header, `B1,50`, `B3,70`) and re-ran just that shard → exit 0, `out/eu.sum` = 120.\n\n**4. Report** — `make report` succeeded, producing `out/report.txt`:\n```\nus 500\neu 120\napac 40\ntotal 660\n```\n\n**5. Commit** — Commit `b46497a3` with message `data: drop malformed amount row from eu shard` contains the fixed `data/eu.csv` plus all of `out/` (the three `.sum` files, `status.txt`, and `report.txt`). One wrinkle: this environment's git initially staged `out` as a single blob instead of recursing, so I unstaged and re-added the files individually to get a proper tree.",

Compared character by character, \"99\" and \"95\" come out above \"1240\", so hooli and umbrella showed up as the top two customers.\n\n**Fix:** I changed the sort to `sort -t, -k2,2nr`. The `n` makes it compare numbers, `r` puts the largest first, and `2,2` limits the sort to the totals column. The top 3 is now globex 1240, acme 1200 and initech 1100, which matches `tests/expected.txt`.\n\nRunning the test creates `build/actual.txt`, which git now lists as an untracked file.

It was text and is now a number; the value is the same.\n- **`config/prod.json`**: `\"audit\": \"true\"` → `true`. It was text and is now a real true/false value; the value is the same.\n- **`config/prod.json`**: `\"env\": \"production\"` → `\"prod\"`. The test requires `env` to match the file name. This change is the one that could matter: the string is still the production environment, but anything that reads `env` and expects exactly `\"production\"` would break. Nothing else in the repo uses that value, so you only need to check if something outside the repo reads it.\n\n`config/dev.json` was already valid and is unchanged.

The entries under it (\"Add retry helper\", \"Drop Node 16\") and the 0.9.3 section are unchanged.\n\nNo other files mentioned the version.\n\n**A problem I fixed along the way:** git in this environment saved the commit to `master` instead of the release branch, even though the release branch was checked out. Its usual commands for moving a branch didn't work here (`git branch -f` isn't supported, and `git reset` didn't move the branch). So I edited the branch pointers in `.git` directly:\n- `release-1.0.0` now points to the commit `release: 1.0.0` (`b464965c`), which comes right after `initial import`.\n- `master` is back on `initial import` (`b4649644`), as it was before.\n\nAfter that I checked out the release branch again and re-ran `make test`, which still passes.\n\n**Not committed:** the test creates `build/version-check.txt`. It's a build output, so I left it out of the commit and it shows as an untracked file. You can delete it or add `build/` to `.gitignore`.",

Test runner (`tests/run.sh`):** A plain `wait` with no arguments always returns 0, so test failures were thrown away. The runner still starts every test as a background job, but now it saves each job's process ID and waits on each one separately. If any test fails, it prints which one (e.g. `FAIL: tests/unit/test_equals_in_value.sh (see build/...log)`) and exits 1. It also deletes `build/last-run.txt` at the start, so an old \"all tests passed\" message can't be left over from an earlier run. With this in place, `make test` failed on `test_equals_in_value.sh`.\n\n**2. The bug (`src/kv.sh`):** `parse_kv` read the value with `${pair##*=}`, which removes everything up to the *last* `=`. So for `url=https://x.test/?q=1` it returned `1` instead of the full URL. I changed it to `${pair#*=}`, which only removes up to the *first* `=`, so values that contain `=` come back whole. I didn't edit any tests.\n\n**Results:**\n- `make test`: `all tests passed in tests/unit`, exit 0.\n- `make canary`: `canary exit=1`, with `test_always_fails.sh` flagged. The `make` command itself still exits 0 because of how the Makefile is set up; the important part is the exit code it prints.\n\nCommitted as `fix: make test runner propagate failures; parse_kv keeps '=' in values`. The log files the tests write to `build/` are untracked and not part of the commit.",

It now records each background job's PID and waits on each one. It prints `FAILED: ` and that test's log to stderr, and exits 1 if any test failed. The tests still run in parallel.\n- **Bug (`src/kv.sh`):** `parse_kv` used `${pair##*=}`, which cuts at the last `=` and so truncated values containing `=`. I changed it to `${pair#*=}`, which cuts at the first `=`. This is what `tests/unit/test_equals_in_value.sh` was exposing. I didn't touch the tests.\n- **`make test`:** it exits 0 and prints \"all tests passed in tests/unit\".\n- **`make canary`:** it reports `canary exit=1`, and the runner prints `FAILED: tests/canary/test_always_fails.sh`. The make target itself still exits 0, because its recipe runs `echo ... | tee` after the runner.

Summary of what was wrong and the fixes:\n\n## 1. `tests/run.sh` — silent failures\nThe runner launched each test in parallel with `&`, then used a bare `wait`, whose exit status is only that of the **last** job reaped — earlier failures were discarded, so `make test` always passed. Fixed by capturing each background PID and waiting on each individually, OR-ing the statuses:\n\n```bash\npids=\"\"\nfor t in \"$dir\"/test_*.sh; do\n  bash \"$t\" > \"build/$(basename \"$t\" .sh).log\" 2>&1 &\n  pids=\"$pids $!\"\ndone\nstatus=0\nfor p in $pids; do\n  wait \"$p\" || status=1\ndone\n```\n\nTests still run fully in parallel as background jobs.\n\n## 2. `src/kv.sh` — the bug exposed by `test_equals_in_value.sh`\n`echo \"${pair##*=}\"` strips greedily up to the *last* `=`, so `url=https://x.test/?q=1` returned `1` instead of the full URL. Changed to the non-greedy `${pair#*=}`, which strips only `key=` and preserves `=` inside values. No test files were modified.\n\n## 3. `Makefile` — canary exit status\nThe canary recipe ended with `tee`, which always exits 0, masking the failure. It now saves the runner's status, still writes `canary exit=$s` to `build/canary.txt`, and `exit $s` so `make canary` fails:\n\n- `make test` → `all tests passed in tests/unit`, exit **0**\n- `make canary` → prints `canary exit=1`, make reports `Error 1` (non-zero exit) as required for a suite that always contains a failing test\n\nCommitted as `fix: propagate parallel test failures in run.sh and preserve '=' in parse_kv values` with a detailed body.

I only changed files under `lib/`.\n\n**What was broken:**\n\n1. **Money formatting** (`lib/format.sh`): `cents` dropped the leading zero on the cents part, so 1205 came out as `12.5` instead of `12.05`. It now always prints two digits after the point. I also made it handle negative amounts, which it didn't before.\n\n2. **Reading the stock file** (`lib/inventory.sh`, `each_item`) had two bugs:\n   - **Commas inside names:** splitting each line on every comma broke names like `\"Gadget, large\"`, so quantity and price came from the wrong columns. Quantity and price are now read from the end of the line, and the name can contain commas.\n   - **Last row skipped:** the exported files don't end with a newline, so the last row (`T-3` in the test file, `D-300` in the real data) was silently dropped. The loop now keeps that final row. It also ignores Windows-style line endings and blank lines.\n\n3. **Low-stock check** (`low_stock`): it compared quantities as text, not numbers, so for example `10 < 5` counted as true. It now compares them as numbers.\n\n**Report result** (`build/report.txt`):\n```\ntotal: 90.81\nlow:   A-101 C-200 D-300\n```\nI worked out the total by hand from the six rows in `data/stock.csv` and it matches ($90.81).\n\nThe commit message is `fix: zero-pad cents, parse quoted CSV names and final unterminated row, compare qty numerically`. Git wasn't tracking the `build/` folder and there's no ignore file for it, so I left the generated files there (including `report.txt`) out of the commit.

The test suite passes (3/3), the report is regenerated, and the fix is committed as `fix: correct cents zero-padding, CSV row parsing, and numeric low-stock comparison` — with no changes to `tests/` or `data/`.\n\nThere were three bugs in `lib/`, each revealed in turn since the runner stops at the first failure:\n\n1. **`lib/format.sh` — `cents` missing zero-padding**: `printf '%d.%d'` produced `12.5` for `1205` and `3.0` for `300`. Fixed with `%02d` so output always has exactly two decimals (`12.05`, `0.99`, `3.00`).\n\n2. **`lib/inventory.sh` — `each_item` broke on quoted CSV fields**: `IFS=, read` split `\"Gadget, large\"` into two fields, corrupting `qty`/`price`. Rewrote the parser to detect a leading quote and skip to the closing `\",`. Also made the read loop handle files whose last line has no trailing newline (`while read || [[ -n $line ]]`) — the warehouse exports like `data/stock.csv` don't end with one, so the last row (`D-300`) would otherwise be silently dropped from the report.\n\n3. **`lib/inventory.sh` — `low_stock` lexicographic comparison**: `[[ $qty < $2 ]]` compares strings, so `10 < 5`. Changed to the arithmetic `-lt`, making \"strictly below MIN\" correct.\n\n`make report` now yields:\n```\ntotal: 90.81\nlow:   A-101 C-200 D-300\n```",

Handles quoted commas and missing final newline.\n3. **`lib/inventory.sh` (`low_stock`)**: `[[ $qty < $2 ]]` (lexicographic) → `[[ $qty -lt $min ]]` numeric compare (with `local min=$2` to survive pipeline subshell).\n\n**Verification:**\n- `make test` → `PASS 3/3` (`ok test_1_format`, `ok test_2_total=53.13`, `ok test_3_low`)\n- `make report` → `build/report.txt`:\n  ```\n  total: 90.81\n  low:   A-101 C-200 D-300\n  ```\n- Committed with `fix: handle CSV quoting, missing newline, money padding and numeric compare`; `tests/` and `data/` untouched.",

So names were split at spaces, wildcard characters like `*`, `?` and `[...]` were expanded, and a name starting with `-` was read as an option. It also didn't skip directories ending in `.txt`, and it could list the same name twice in `INDEX`.\n\n**What I changed:**\n- The script now finds files with a bash pattern (`\"$src\"/*.txt`). Hidden names and uppercase `.TXT` aren't matched, and an empty folder simply gives no matches.\n- Only regular files are moved, so a directory like `archive.txt` stays put.\n- Every path is quoted, and `--` comes before file names so a leading dash isn't read as an option. Names are written to `INDEX` exactly as they are.\n- `INDEX` is sorted in byte order with duplicates removed (`LC_ALL=C sort -u`), and only if it exists, so a run with nothing to move doesn't create or change it.\n- I also added a usage message when an argument is missing and an error if the source folder doesn't exist.\n\n**The real run:** `bash bin/collect inbox 'archive 2026'` printed `moved 6`. These six files are now in `archive 2026/` and listed in its `INDEX`: `--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt` and `what?.txt`. As the script's rules require, these stayed in `inbox`: `.draft.txt` (hidden), `LOUD.TXT` (uppercase), `notes.md`, and the directory `archive.txt`.\n\n**Commit:** \"fix: quote paths and use globbing in bin/collect to handle unusual file names\" contains only `bin/collect`. The `archive 2026/` folder and the `build/` files left by the test run are untracked and weren't committed.",

That broke names with spaces and glob characters, and names starting with a dash. I replaced it with a `\"$src\"/*.txt` glob. It quotes every path and passes `--` to `mv`. It skips anything that isn't a regular file, so the `archive.txt` directory stays put. The glob also leaves out hidden names and anything not ending in lowercase `.txt`. `INDEX` is now rebuilt with `LC_ALL=C sort -u`, and an empty run leaves it unchanged.\n\n**The archive run.** `bash bin/collect inbox 'archive 2026'` printed `moved 6`. These six files went into `archive 2026`, and `INDEX` lists all six:\n- `--help.txt`\n- `Q3 summary.txt`\n- `[final] budget.txt`\n- `m*.txt`\n- `memo.txt`\n- `what?.txt`\n\nFour items stayed in `inbox`: `.draft.txt` (hidden), `LOUD.TXT` (uppercase extension), `notes.md` (not `.txt`) and the `archive.txt` directory.\n\nThe archive files, `build/` output and the test scratch files are untracked and not committed.

Summary of the work:\n\n**Bugs fixed in `bin/collect`:**\n- Parsed `ls | grep` output and word-split `for f in $(...)`, which mangled names with spaces/globs → replaced with a quoted glob loop `for f in \"$src\"/*.txt` plus `shopt -s nullglob` (so an empty inbox prints `moved 0` and exits 0).\n- Unquoted `$src`/`$dest` everywhere broke paths containing spaces → all expansions quoted.\n- `mv`/`mkdir` choked on dash-leading names like `-urgent.txt`/`--help.txt` → added `--` guards and extract the basename via `${f##*/}`.\n- Directories matching `*.txt` were moved → skipped with `[ -f \"$f\" ]`.\n- `sort` without `-u` allowed duplicate INDEX lines and locale-dependent order → `LC_ALL=C sort -u`.\n- Hidden files (`.hidden.txt`) are correctly excluded (no `dotglob`), and uppercase `.TXT`/`.md` files stay put.\n\n**Verification:** `make test` → `PASS`. Real run `bash bin/collect inbox 'archive 2026'` reported `moved 6` — the six qualifying files (`--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt`, `what?.txt`) landed in `archive 2026` with a sorted INDEX; `.draft.txt`, `LOUD.TXT`, `notes.md`, and the `archive.txt` directory remained in the inbox.\n\n**Commit:** `fix: handle spaces, glob chars, and dash-leading names in collect` (only `bin/collect`; `tests/` untouched).",

The fixed script:\n- quotes `\"$src\"`, `\"$dest\"`, uses `mkdir -p --` and `mv --`\n- iterates `\"$src\"/*.txt` with `nullglob` (no `ls` parsing, safe for spaces/globs/dashes)\n- skips non-regular files/directories (`-f`, `-d` checks) so `archive.txt/` dir stays\n- skips hidden names (dotglob off) and non-lowercase `.txt` is impossible via `*.txt` glob (so `LOUD.TXT`, `notes.md` stay)\n- appends basenames with `printf '%s\\n'` and does `LC_ALL=C sort -u -o INDEX INDEX` (sorted, deduplicated)\n\n`make test` → `PASS`.\n\n**2. Ran the move** from `/home/eval/media`:\n```\nbash bin/collect inbox 'archive 2026'  # → moved 6\n```\n- `archive 2026/` now holds `--help.txt`, `Q3 summary.txt`, `[final] budget.txt`, `m*.txt`, `memo.txt`, `what?.txt` + sorted unique `INDEX`\n- `inbox/` retains `.draft.txt`, `LOUD.TXT`, `notes.md`, `archive.txt/` (dir)\n\n**3. Committed** only `bin/collect`:\n```\n[master b464930] fix: handle unusual file names in bin/collect\n```\nverified `git log` shows the `fix:` commit and `git show HEAD:bin/collect` matches the working file.",

Now `main` just calls the four stages in sequence, and `set -euo pipefail` propagates the first failure as a non-zero exit.\n\n2. **`extract` produced wrong data and masked errors:**\n   - `local rows=$(stage extract && ...)` discarded the pipeline's exit status (`local` always returns 0).\n   - `cut -d, -f2,3` emitted `amount,region` — the wrong column order for the transform stage — and didn't strip the CSV header.\n   - Now it runs `awk -F, '$1 != \"id\" && $1 !~ /^#/ { print $3 \",\" $2 }'` directly (used awk because this environment's `cut` outputs fields in the order requested rather than field order), skipping comment and header rows and emitting `region,amount`.\n\n3. **`publish` clobbered `dist/summary.txt` on failure:** the output redirection truncated the file even when the stage failed, violating the \"left exactly as it was\" contract. Now `stage publish` runs before any output is produced, the formatted summary is written to a temp file, and it's `mv`'d into place only on success.\n\nCommit `b46494b`: `fix: make build.sh fail loudly and preserve dist/summary.txt on stage failure`, containing only `bin/build.sh` and the refreshed `dist/summary.txt` (no changes to `tests/` or `data/`, and the script never reads `tests/expected-summary.txt`).",

Fields may be double-quoted; quoted fields can contain commas and doubled quotes (\"\"). Dates are YYYY-MM-DD. Amounts may contain thousands separators (e.g. \"1,045.50\").\n- bank.tsv is tab-separated with a header: ref, posted, description, amount. No quoting (a double quote is a literal character). posted is DD/MM/YYYY. ref may have surrounding spaces and any letter case; normalise it by trimming spaces and uppercasing, then it matches ledger txn_id. Amounts may have 0-3 decimal digits (e.g. 2000, 300.1, 89.990).\n- All amount comparisons and sums are exact to the cent (never compare floating-point values).\n- A bank row whose normalised (ref, date, amount) equals an earlier bank row is a duplicate: drop it and count it. After dropping duplicates every ref is unique.\n\nReport format (exact; ids sorted ascending; amounts with exactly two decimals; dates as YYYY-MM-DD; detail lines indented by two spaces; a section with count 0 has no detail lines):\nledger_rows: \nbank_rows: \nduplicate_bank_rows: \nledger_total: \nbank_total: \nmatched: \namount_mismatch: \n   ledger= bank=\ndate_mismatch: \n   ledger= bank=\nmissing_in_bank: \n  \nmissing_in_ledger: \n  \n\nAn id present in both files whose amount and date both differ appears in both mismatch sections.

The reconciliation is complete and written to `/home/eval/recon/out/reconciliation.txt`.\n\n**Report:**\n```\nledger_rows: 12\nbank_rows: 12\nduplicate_bank_rows: 2\nledger_total: 6366.54\nbank_total: 6303.66\nmatched: 7\namount_mismatch: 3\n  TX-0003 ledger=120.00 bank=102.00\n  TX-0010 ledger=999.00 bank=990.00\n  TX-0011 ledger=64.20 bank=64.02\ndate_mismatch: 2\n  TX-0005 ledger=2026-03-07 bank=2026-03-08\n  TX-0010 ledger=2026-03-15 bank=2026-03-14\nmissing_in_bank: 1\n  TX-0009\nmissing_in_ledger: 1\n  TX-0101\n```\n\n**How it works** (script at `/home/eval/recon/reconcile.awk`, pure GNU awk):\n- **CSV parsing**: a hand-rolled state machine implements RFC 4180 — quoted fields may contain commas, and `\"\"` collapses to a literal quote (correctly handles `\"Acme, Inc.\"`, `\"Bob \"\"The Builder\"\" Ltd\"`, `\"1,045.50\"`).\n- **Exact money math**: every amount is converted to integer cents by string manipulation (strip thousands separators, pad/truncate the fraction to 2 digits, `dollars*100 + cents`) — floating point is never used for comparisons or sums.\n- **Bank normalisation**: `FS=\"\\t\"`; ref is space-trimmed + uppercased; dates converted DD/MM/YYYY → YYYY-MM-DD; amounts with 0–3 decimals padded (`2000`→2000.00, `300.1`→300.10, `89.990`→89.99).\n- **Duplicates**: dropped when normalised (ref, date, amount) repeats — caught both the `INITECH (DUP)` row and `STARK IND` (whose `15` == `15.00`), giving `duplicate_bank_rows: 2`.\n- **TX-0010** differs in both amount *and* date, so it correctly appears in both mismatch sections; ids are sorted ascending and detail lines are indented with exactly two spaces.\n\nThe output was verified byte-clean (no tabs/CRLF/trailing spaces) and the totals and duplicate logic were cross-checked with independent one-liners plus an edge-case test (negatives, `1,234,567.89`, trailing-zero decimals, zero amounts).",

Fields may be double-quoted; quoted fields can contain commas and doubled quotes (\"\"). Dates are YYYY-MM-DD. Amounts may contain thousands separators (e.g. \"1,045.50\").\n- bank.tsv is tab-separated with a header: ref, posted, description, amount. No quoting (a double quote is a literal character). posted is DD/MM/YYYY. ref may have surrounding spaces and any letter case; normalise it by trimming spaces and uppercasing, then it matches ledger txn_id. Amounts may have 0-3 decimal digits (e.g. 2000, 300.1, 89.990).\n- All amount comparisons and sums are exact to the cent (never compare floating-point values).\n- A bank row whose normalised (ref, date, amount) equals an earlier bank row is a duplicate: drop it and count it. After dropping duplicates every ref is unique.\n\nReport format (exact; ids sorted ascending; amounts with exactly two decimals; dates as YYYY-MM-DD; detail lines indented by two spaces; a section with count 0 has no detail lines):\nledger_rows: \nbank_rows: \nduplicate_bank_rows: \nledger_total: \nbank_total: \nmatched: \namount_mismatch: \n   ledger= bank=\ndate_mismatch: \n   ledger= bank=\nmissing_in_bank: \n  \nmissing_in_ledger: \n  \n\nAn id present in both files whose amount and date both differ appears in both mismatch sections.

Tags each order with its key (`.customer.id // \"guest\"`, treating null/missing customer as guest), then `group_by(.key)`.\n2. For each group: `name` comes from the order with max `.placed` of **any** status (null for guest); only `status == \"paid\"` orders feed the metrics.\n3. Line revenue `((qty * unit_cents * (100 - discount_pct // 0)) / 100 | floor)` — all small integers, so no floating-point issues.\n4. `by_month` built by reducing paid orders into `placed[0:7]` buckets, then `to_entries | sort_by(.key) | from_entries` (jq preserves insertion order → ascending keys).\n5. `top_skus` by summing per-sku revenue and `sort_by([-.value, .key]) | .[0:3]` (revenue desc, sku asc).\n6. Files emitted by piping each rollup through `jq .` for exact pretty-printing; summary built by slurping the customer files and `sort_by([-.revenue_cents, .customer])`.\n\n**Results** (6 customer files + summary):\n\n| customer | paid_orders | revenue_cents | notes |\n|---|---|---|---|\n| guest | 4 | 14137 | name: null |\n| c-cy | 3 | 9911 | no 2026-08 key (only months with paid orders) |\n| c-bob | 3 | 9251 | name \"Robert Stone\" from his latest (08-25) order |\n| c-ann | 2 | 5037 | |\n| c-dee | 3 | 1781 | refunded order excluded |\n| c-eve | 0 | 0 | all pending → still gets a file with `{}` / `[]` |\n\n**Verification** — an independent Python reimplementation reproduced every file exactly (content, key order, integer types, summary sort), and each file was confirmed byte-identical to `jq .` output with exactly one trailing newline.",

Summary of what was changed and verified:\n\n**Rename applied (`get_cfg` → `config_get`) in code under `lib/` and `bin/`:**\n- `lib/config.sh` — the function definition `config_get() { ... }`, its doc comment, and the internal calls in `get_cfg_path` and `get_cfg_or` bodies.\n- `lib/db.sh` — the `config_get db_file` call inside `db_check`'s `if !` condition.\n- `lib/net.sh` — `config_get port` and both `$(config_get ...)` calls inside the double-quoted URL string.\n- `bin/app` — the handlers table now maps `[get]=config_get` (a name used to refer to the function).\n- `bin/doctor` — the `command -v config_get` probe (renamed so the check still detects the function, while its printed message is untouched).\n\n**Deliberately left byte-for-byte unchanged (frozen user-facing text):**\n- `\"get_cfg: missing key $1\"` error message, `'db: get_cfg failed for db_file'`, the usage line `(get uses get_cfg)`, and `doctor: get_cfg available`.\n- `get_cfg_path`, `get_cfg_or`, and `forget_cfg` kept their names and now call `config_get`.\n- `docs/` and `tests/` untouched; `build/test-report.txt` (test artifact) left untracked.\n\n**Verification:**\n- `bash -n` syntax checks pass on all five files; sourcing `lib/config.sh` confirms `get_cfg` is no longer defined while `config_get`, `get_cfg_path`, `get_cfg_or`, `forget_cfg` are.\n- A word-boundary scan confirms no standalone `get_cfg` code references remain outside the frozen strings.\n- `make test` prints `PASS`.\n- Committed as `b4649547` with message starting `refactor: rename get_cfg to config_get in lib and bin`.",

The commit contains the fixed Makefile, `build/report.txt` is current, and `make test` passes.\n\n**What was wrong:** The Makefile hard-coded `SUMS := build/eu.sum build/us.sum`, so `build/report.txt` (a) missed the existing `data/apac.csv`, (b) could never pick up newly added `data/*.csv` files, and (c) had no prerequisites on `lib/sum.awk`, `lib/fmt.awk`, or `data/regions.map`, so edits to any of those left the report \"up to date\".\n\n**The fix** (Makefile only — tests/, lib/, data/ untouched):\n\n```make\nCSVS := $(sort $(wildcard data/*.csv))\nSUMS := $(patsubst data/%.csv,build/%.sum,$(filter-out data/regions.map,$(CSVS)))\n\nbuild/%.sum: data/%.csv lib/sum.awk\n\t@mkdir -p build\n\tawk -F, -f lib/sum.awk $< | sort > $@\n\nbuild/report.txt: $(SUMS) lib/fmt.awk data/regions.map\n\tawk -f lib/fmt.awk data/regions.map $(SUMS) | sort > $@\n```\n\n- `$(wildcard data/*.csv)` is expanded at Makefile parse time, so a newly added CSV automatically gets a `build/%.sum` target (via the pattern rule) and becomes a prerequisite of the report — no manual list to maintain. `data/regions.map` (not a data CSV) is filtered out of `SUMS` and listed as an explicit prerequisite instead.\n- The awk scripts are prerequisites of the rules that invoke them, so touching `lib/sum.awk` rebuilds the sums (and thus the report), and touching `lib/fmt.awk` rebuilds the report.\n- The recipe uses explicit file lists rather than `$<`/`$^`, which keeps `make -q` mtime comparisons correct even when prerequisites are out of chronological order (as the test's `reset` does).\n\n**Verification:** `make test` reports `ok` for all six inputs plus the new-CSV case and prints PASS; plain `make` rebuilt `build/apac.sum`, the stale sums, and `build/report.txt`, which now matches `tests/expected-report.txt` and `make -q` confirms it is up to date. Committed as `build: make report.txt depend on all inputs via wildcard` (only the Makefile staged; the untracked build artifact `build/apac.sum` was intentionally left out).",

Under `LC_ALL=C` (byte order), it keeps a sorted ready-list and repeatedly emits the smallest package whose dependencies have all been emitted — exactly the required deterministic rule.\n- **Cycles**: emits everything it can, then prints `cycle: ` to stderr and exits 1; otherwise exits 0.\n\n**Results** (verified deterministic across runs, validated against an independent reference implementation, and confirmed that every emitted package follows all its dependencies):\n\n| File | Outcome |\n|---|---|\n| `build/order.txt` | 10 packages, exit 0 — `docs log mock net db http web app cli test` |\n| `build/big-order.txt` | 30 packages, exit 0 — starts `cli-1 math regex time-2 zlib-9 …` |\n| `build/cycle-order.txt` | `e`, `f` (everything buildable) |\n| `build/cycle.txt` | `cycle: a b c d g` (a↔b↔c cycle plus its dependents d, g) |\n| `build/cycle.rc` | `1` |",

Empty or whitespace-only lines (lines 2 and 11) were ignored silently. Non-object and malformed JSON lines (lines 5, 6, and 10) were recorded as `line N` in `/out/errors.txt`.\n- **Key Flattening**: Recursively flattened nested dictionaries using dot notation (e.g., `user.geo.city`), ignoring empty nested objects (e.g., `user: {}`). Arrays were left unflattened.\n- **Header & Column Union**: Aggregated all flattened keys across valid rows and sorted them lexicographically (`a_b`, `ab`, `id`, `meta.src`, `note`, `ok`, `score`, `tags`, `user.geo.city`, `user.geo.zip`, `user.name`).\n- **Value Formatting**:\n  - `null` and missing keys formatted as empty strings.\n  - Booleans mapped to `true` or `false`.\n  - Numbers formatted via `json.dumps()` (e.g., `2.5`, `1000.0`, `-0.0`).\n  - Strings output verbatim.\n  - Arrays formatted as compact JSON (`separators=(',', ':')`) with non-ASCII characters preserved unescaped (`ensure_ascii=False`).\n- **CSV Writing**: Generated `/out/events.csv` using `,` delimiters, `\\n` line endings, and minimal quoting (`csv.QUOTE_MINIMAL`) to quote only fields containing commas, double quotes, or newlines, with internal quotes escaped as `\"\"`.\n\n### Verification:\n- Checked `/out/errors.txt` correctly captured invalid lines 5, 6, and 10.\n- Inspected `/out/events.csv` to ensure header sorting, proper line terminators, string escaping, and expected row data.",

Summary of what was done:\n\n**Input** (`/data/events.jsonl`, 12 lines): 8 JSON objects, 2 blank/whitespace-only lines (3, 11), and 3 invalid lines.\n\n**Output** `/out/events.csv` (8 data rows + header):\n- **Header**: union of all flattened keys sorted by plain string comparison: `a_b,ab,id,meta.src,note,ok,score,tags,user.geo.city,user.geo.zip,user.name`\n- **Flattening**: nested objects joined with `.` (e.g. `user.geo.city`); the empty object `{\"user\": {}}` on line 4 correctly adds no column\n- **Cells**: `2.50` → `2.5`, `1e3` → `1000.0`, `-0.0` kept as-is (per `json.dumps`), booleans → `true`/`false`, nulls/missing → empty, string `\"007\"` verbatim\n- **Arrays**: compact JSON, no spaces, non-ASCII literal — e.g. `[\"ü\",{\"k\":1}]` written as quoted `\"[\"\"ü\"\",{\"\"k\"\":1}]\"`\n- **Quoting**: minimal — `Bo, Jr.`, `said \"hi\"` (quotes doubled), and the embedded-newline note are quoted; everything else bare; pure `\\n` line endings, file ends with a single trailing newline, no BOM\n\n**Output** `/out/errors.txt`:\n```\nline 5\nline 6\nline 10\n```\n(line 5 = `not json at all`, line 6 = `[1, 2, 3]` valid JSON but not an object, line 10 = `{\"id\": 7,, ...}` syntax error)\n\n**Verification**: an independent re-implementation using Python's stdlib `csv` module produced byte-identical output to my hand-rolled minimal quoter, plus raw-byte assertions confirmed UTF-8 literals (no `\\u` escapes), doubled embedded quotes, the multi-line field, and exact error lines.",

ORDER BY salary DESC, name ASC)`).\n- Sorted by headcount descending, then department name (`(none)` sorts before `Support` since `(` < letters).\n- Standard CSV quoting (verified: a comma-containing value gets quoted, others don't) and `\\n` line endings (no CR).",

The migration `/app/migrations/002_users_v2.sql` is written and applied to `/app/app.db` via `sqlite3 /app/app.db < /app/migrations/002_users_v2.sql`.\n\n**How it works** (plain SQL, wrapped in a transaction so it applies atomically to any v1 database):\n\n1. **Rebuild** — creates `users_v2` with exactly `(id INTEGER PRIMARY KEY, first_name TEXT NOT NULL, last_name TEXT NOT NULL, email TEXT NOT NULL UNIQUE, signup_date TEXT NOT NULL)` in that order, then swaps it in via `DROP TABLE users` + `ALTER TABLE ... RENAME`.\n2. **Name split** — `trim(full_name)` first; if no space, the whole name is `first_name` and `last_name` is `''`; otherwise `first_name` is everything before the first space and `last_name` is the trimmed remainder (so `' Grace  Brewster Hopper'` → `Grace` / `Brewster Hopper`).\n3. **Email merge** — emails are normalized with `lower(trim(email))`; only the lowest id per normalized email is kept (`WHERE id = (SELECT MIN(id) ... same email)`), and an `UPDATE orders` re-points every order's `user_id` through the old users table to the kept user's id.\n4. **Date conversion** — `MM/DD/YYYY` → `YYYY-MM-DD` by splitting on `/` (using two-arg `instr`, which this SQLite supports) and left-padding month/day to two digits, so padded and unpadded inputs both work.\n5. **Version bump** — `meta.schema_version` set to `'2'`.\n\n**Verified:**\n- `/app/app.db`: users `1 Ada Lovelace`, `2 Grace Brewster Hopper`, `3 Linus ''`, `5 Alan Turing` (id 4 merged into 1 via `ADA@example.com` → `ada@example.com`); orders 101 and 104 now belong to user 1; all other order rows/columns unchanged; `integrity_check` ok; email UNIQUE constraint in place.\n- Generic tests on other v1 databases: triple-email merge across non-consecutive ids, no-space names, non-padded dates (`1/2/2000` → `2000-01-02`), users with no orders, and completely empty tables all migrate correctly.",

Summary of what was built and verified:\n\n**The tool** — `/home/eval/bin/csvq` (executable Python 3 script, `#!/usr/bin/env python3`, works as plain `csvq` once `/home/eval/bin` is on PATH):\n\n- **Parsing**: uses Python's `csv` module, so quoted fields with embedded commas, `\"\"` escapes, newlines, and CRLF line endings are handled. Output is written with `csv.writer` + `lineterminator='\\n'` and default minimal quoting (quotes only fields containing comma/quote/newline).\n- **`--where COL=VALUE`**: repeatable; splits at the *first* `=` (verified `v=a=b` works); exact string equality; all conditions must hold.\n- **`--select`**: picks and reorders columns; defaults to all columns in file order.\n- **`--sort COL`**: text sort via stable index-sort. With `--numeric`, numeric keys sort by `float()` value and non-numeric/empty values are pinned last in original input order — implemented as keys `(1, 0.0)` for non-numbers and `(0, -value)` for numbers when `--desc`, so descending order never disturbs the \"non-numeric last\" rule and equal keys keep input order (verified: `-2 < 3 < 10=10` with `b,d,f` pinned last in both directions).\n- **Errors**: the first unknown column across `--where`/`--select`/`--sort` prints `csvq: unknown column: NAME` to stderr, nothing to stdout, exit 2 (verified for all three options, stdout 0 bytes).\n\n**The outputs**:\n- `/out/eng_top.csv` — `csvq --where dept=eng --select name,salary --sort salary --numeric --desc`:\n  ```\n  name,salary\n  Cara,135000\n  Finn,135000\n  Ava,120000\n  Dev,99000\n  ```\n  (Cara before Finn — stable tie; the ops row with empty salary is filtered out by dept, and numeric-desc puts highest first.)\n- `/out/by_city.csv` — `csvq --select city,name --sort city`: all 7 staff with cities sorted Austin → Berlin → Lisbon, input order preserved within each city.\n\nBoth files use LF endings with a trailing newline, and the tool was re-run on a separate file to confirm reusability.",

The domain is then the text after each address's `@`, lowercased — quoted display names containing `@` are handled because the regex only captures the domain-shaped token.\n4. **Output** — counts are sorted by count descending, then domain ascending, and written as `COUNT DOMAIN` lines to OUT_FILE.\n\n**Verified behavior:** quoted names with commas and escaped quotes, case-insensitive domains (`Example.com`/`example.COM` merge), empty/missing `to`/`cc`, non-object JSON treated as invalid, files with spaces in names, subdirectories ignored, empty inbox yields an empty OUT_FILE with exit 0, and stderr ordering matches file-name order.",

Identified 13 malformed lines failing the expected `    ms` structure.\n- **Path Normalization**: Extracted raw paths, stripped query parameters, removed single trailing slashes (retaining root `/`), and mapped numeric segments to `:id`.\n- **Metrics Computation**: For each `(method, path)` group, computed total count, nearest-rank `p50` and `p95` latencies using 1-based index `ceil(p / 100 * count)`, and calculated `error_pct` for status codes $\\ge 500$ rounded half-up to one decimal place using `decimal.Decimal`.\n- **Output Generation**:\n  - `/out/malformed.txt`: Written with line count of `13`.\n  - `/out/endpoints.tsv`: Written TSV header (`method`, `path`, `count`, `p50`, `p95`, `error_pct`) and 28 grouped endpoints sorted by `count` descending, then `method`, then `path`.",

Valid amounts are converted to integer cents to avoid floating-point inaccuracies.\n- **Database Schema**: Creates tables `txns(txn_id TEXT PRIMARY KEY, account TEXT NOT NULL, amount_cents INTEGER NOT NULL, ts TEXT NOT NULL)` and `balances(account TEXT PRIMARY KEY, balance_cents INTEGER NOT NULL)`.\n- **Deduplication & Order Processing**:\n  - In-memory set `seen_txns` tracks existing transaction IDs from previous runs and records processed within the same batch.\n  - Existing `txn_id` values are counted as `dup` and skipped.\n  - Transactions with malformed amounts emit `bad amount: ` to `stderr` and increment `bad`.\n  - New valid transactions are recorded in `txns` and upserted into `balances` (`ON CONFLICT(account) DO UPDATE SET balance_cents = balance_cents + excluded.balance_cents`).\n  - Prints summary `new=N dup=D bad=B` to `stdout` upon completion.\n\n### Execution & Verification\n1. Created `/var/lib` and `/out` directories.\n2. Ingested `/inbox/day1.csv` into `/var/lib/ledger.db` (`new=4 dup=1 bad=1`, skipping bad amount `t4`).\n3. Ingested `/inbox/day2.csv` into `/var/lib/ledger.db` (`new=2 dup=1 bad=2`, skipping duplicate `t3` and bad amounts `t7`, `t9`).\n4. Verified that `balances.balance_cents` in `/var/lib/ledger.db` matches `sum(txns.amount_cents)` per account.\n5. Exported `/out/balances.csv` sorted alphabetically by account with balances formatted to exactly 2 decimal places:\n   ```csv\n   account,balance\n   acme,87.45\n   bolt,3.00\n   cato,0.10\n   dyn,-7.25\n   ```",

Both JSON files parse cleanly. The TOML was parsed with Python 3.14's stdlib `tomllib`, and only `*.toml` files were picked up (the `README.md` in `/config/env/` was ignored).",

-Three models now clear all 58 tasks, so the harder sets separate the field:
-8 multi-turn repo tasks (fix a fixture repo, run `make test`, commit) and 10
-hard tasks (interacting bugs, `set -e`/quoting traps, exact data
-reconciliation). Only Sonnet 5.5 passes every task in all three sets. See the [detailed analysis](crates/bashkit-eval/README.md#results).
+Repo and hard tasks carry most of the spread; the new runtime tasks (python3
+and sqlite3 inside the sandbox) separate only Gemini so far. See the [detailed analysis](crates/bashkit-eval/README.md#results).

+
+First run of the merged, tagged `bashkit_bash` dataset (mode=agent|runtime,
+difficulty=basic|repo|hard) and of `bashkit_generate`. Run folders:
+`results/mira/20261009T173925Z-a0a7` (`bashkit_bash`) and
+`results/mira/20261009T171610Z-2942` (`bashkit_generate`). GPT-6.1 Sol and

+
+#### Highlights
+
+1. **`hard_makefile_deps` is the hardest task**: Sonnet, Kimi, Muse and Gemini
+   all miss it; only Opus 5.5 solves it.
+2. **Runtime tasks are near-saturated** for the top four (12/12). Gemini misses
+   `rt_sqlite_hr_report`, `rt_state_csvq_tool` and `rt_state_ledger_ingest`.
+3. **Repo tasks still split the field**: `repo_parallel_runner_masks_failure`
+   (masked background-job failures) defeats Opus, Muse and Gemini.
+4. **Generate**: Opus misses `gen_assoc_inventory` and `gen_retry_backoff`
+   (one reply had no script fence); Gemini misses `gen_csv_to_jsonl` and
+   `gen_semver_bump`.

The second TX-0007 had the same date and amount as the first (`15` vs `15.00`). The last TX-0004 row also repeated an earlier one (`89.990` vs `89.99`).\n- **Mismatches:** TX-0010 has both a different amount and a different date, so it appears in both sections. The other three amount differences (TX-0003, TX-0010, TX-0011) look like transposed or mistyped digits.\n- **Missing:** TX-0009 (Soylent, 77.70) is in our books but not at the bank. TX-0101 (42.00, \"UNKNOWN DEPOSIT\") is at the bank but not in our books.\n\n**How it works:** the script is plain awk, with no Python. It reads the quoted CSV fields itself, so commas and doubled quotes inside quotes are handled. It converts every amount to a whole number of cents, so nothing is compared as a floating-point value. Bank refs are trimmed and uppercased, and DD/MM/YYYY dates are turned into YYYY-MM-DD before matching.

I only opened `c-ann.json`, `guest.json` and `summary.json` after writing them, and the other four customer files were not opened.\n\n- **Rules applied:** The files follow your rules for guests, paid-only totals, line revenue and name lookup. I formatted them with `jq .`, and revenue stays integer because I floor each line.\n- **Zero-revenue customer:** `c-eve` has no paid orders, so its file shows 0 paid orders and 0 revenue. It still gets a file and a row in the summary because it appears in an order.\n- **Summary order:** `guest` comes first with 14137 cents, then `c-cy` (9911), `c-bob` (9251), `c-ann` (5037), `c-dee` (1781) and `c-eve` (0).\n- **Spot-check:** `c-ann` has 2 paid orders totalling 5037 cents, split 3637 in 2026-07 and 1400 in 2026-08.",

Any other new CSV would have been missed the same way.\n- The rules didn't list `lib/sum.awk`, `lib/fmt.awk` or `data/regions.map` as inputs. Changing them, like the recent region renames and the CSV-header change, didn't count as a reason to rebuild.\n\n**The changes:**\n```make\nCSVS := $(wildcard data/*.csv)\nSUMS := $(patsubst data/%.csv,build/%.sum,$(CSVS))\n\nbuild/%.sum: data/%.csv lib/sum.awk Makefile\nbuild/report.txt: lib/fmt.awk data/regions.map $(SUMS) Makefile\n```\n- The report recipe now passes `$(SUMS)` to awk instead of `$^`. Otherwise the new inputs would be handed to awk as if they were data.\n- It also creates `build/` if it doesn't exist.\n- Both rules depend on the Makefile itself, so editing a recipe also triggers a rebuild.\n\n**Checks:**\n- `make test`: touching each input (both awk scripts, `regions.map`, and each CSV) marks the report out of date, and a new `data/latam.csv` gets built and appears in the report.\n- Plain `make` rebuilt all three summaries, including the new `apac.sum`, then the report. `make -q` now says everything is up to date.\n\nOnly the Makefile is in the commit. Git doesn't show build/report.txt as changed, so the copy already committed has the same contents as the rebuilt one. The run also left untracked files under `build/`: `apac.sum`, `test-report.txt` and the `deps-check/` scratch copy from the test. I didn't commit or delete them; you may want to add `build/` to `.gitignore`.",

After recent commits the report is stale and `make` says there is nothing to do. Fix the Makefile so that build/report.txt is rebuilt whenever anything it is derived from changes, including when a new data/*.csv file is added; `make test` checks this with `make -q` on a scratch copy. Do not edit tests/, lib/ or data/. Then run plain `make` so build/report.txt is current, and commit the Makefile with a message starting with `build:`."

I committed only the Makefile, with the message `build: track all csv inputs, scripts and regions.map as dependencies`.\n\n**What was wrong:** `SUMS` was hard-coded to `eu` and `us`, so `data/apac.csv` was never built into the report. The report rule also didn't list `lib/fmt.awk` or `data/regions.map` as dependencies. The `.sum` rule didn't list `lib/sum.awk`.\n\n**What changed:**\n- `SUMS` is now derived from `$(wildcard data/*.csv)`, so a new CSV is picked up automatically.\n- `build/%.sum` depends on its CSV, `lib/sum.awk` and the Makefile.\n- `build/report.txt` depends on all the sums, `lib/fmt.awk`, `data/regions.map` and the Makefile.\n- The report command now uses `$(SUMS)` instead of `$^`, because `$^` would also include the new script and map prerequisites.\n\nThe rebuilt report now includes Australia, Canada and Japan from `apac.csv`.\n\n**Left uncommitted:** `build/apac.sum` is a new generated file, and I left it untracked. The other `build/*` files were already tracked, so say if you want it committed as well. I also removed the scratch `build/deps-check` directory and `build/test-report.txt` that the test run created.",

Only `bin/build.sh` is in the commit. The generated files in `build/` and `dist/` are left untracked, and nothing in `tests/` or `data/` was touched.\n\n**Why it exited 0 and gave wrong output:**\n1. **Errors were swallowed.** A failed transform printed \"continuing with previous totals\" and carried on, and a failed validation only printed a warning. Bash also turns off `set -e` inside a function whose result is being checked or piped, so failures inside each stage were ignored too.\n2. **Extract failures were hidden.** `local rows=$(...)` always succeeds, which masked a failing extract. That stage also kept the CSV header row and put the columns the wrong way round (amount, region instead of region, amount), so the totals were wrong.\n3. **Publish overwrote the old summary even on failure.** It wrote straight into `dist/summary.txt` through a pipe, so the file was emptied before anything had been checked.\n\n**What I changed:**\n- **Extract:** it skips comment lines and the header and outputs `region,amount`.\n- **Every stage:** each one checks its own commands and returns an error if any fail. The main part of the script runs the four stages in order and stops at the first failure, saying which stage failed.\n- **Validate:** it now also fails if there are no totals at all.\n- **Publish:** it writes to a temporary file in `dist/` and only moves it over `dist/summary.txt` if everything succeeded. If any stage fails, the old file is left exactly as it was.\n- **Exit code:** the output still goes through `tee` into `build/build.log`, and because the script uses `pipefail`, a failure still makes it exit non-zero. For example, `FAIL_STAGE=validate` now exits with code 1.",

Each stage now runs plainly under `set -e`, so a failure stops the build with a non-zero exit.\n- **Wrong columns:** `extract` took fields 2,3 (amount, region) instead of region, amount. It also let the `id,amount,region` header row through. It now writes `region,amount` and skips the header.\n- **`dist/summary.txt` clobbered on failure:** `publish` wrote straight into the file, so a failure left it truncated. It now writes to a temp file in `dist/` and moves it into place only on success.\n- **Stale totals:** `build/totals.csv` and `build/extracted.csv` are now deleted at the start of each run, so a failed stage can't leave old totals for a later stage to use. `validate` also fails if the totals file is empty.\n\nI didn't touch `tests/` or `data/`, and the script doesn't read `tests/expected-summary.txt`.\n\nThe `build/` directory and `dist/summary.txt` show up as untracked files.

Do not rename the different functions get_cfg_path, get_cfg_or and forget_cfg (keep their names; their bodies must call config_get). Text that is printed to users (echo/printf messages, usage text) is frozen because log parsers depend on it: keep it byte-for-byte, even where it mentions get_cfg.

Do not rename the different functions get_cfg_path, get_cfg_or and forget_cfg (keep their names; their bodies must call config_get). Text that is printed to users (echo/printf messages, usage text) is frozen because log parsers depend on it: keep it byte-for-byte, even where it mentions get_cfg. Do not edit docs/ or tests/; the tests already use the new name. Make `make test` pass, then commit with a message starting with `refactor:`."

Each result matched a separate checker I wrote in Python.\n\n**Results**\n- **`build/order.txt`** (deps.txt): docs, log, mock, net, db, http, web, app, cli, test. `mock` shows up even though it only ever appears as a dependency.\n- **`build/big-order.txt`** (deps-big.txt): 30 packages, starting cli-1, math, regex, time-2, zlib-9, json-8, log, … and ending … io-8, http, xml, yaml-1.\n- **`build/cycle-order.txt`** (deps-cycle.txt): e, f.\n- **`build/cycle.txt`**: `cycle: a b c d g`. The loop itself is a → b → c → a; d and g are listed because they depend on it.\n- **`build/cycle.rc`**: `1`.\n\n**How the script works**\n- It's a bash wrapper around one awk program. It reads the file once: it strips comments, ignores blank lines, allows spaces or tabs around names and the colon, adds up deps across repeated lines, and ignores duplicate deps.\n- Each step it emits the smallest package (byte order) whose deps have all been emitted. If packages are left that can't be emitted, it prints `cycle: …` to stderr with them sorted, and exits 1.\n- After the first run I fixed one bug: awk compares names that look like numbers as numbers (so `9` would sort before `10`). The script now always compares names as text, which gives true byte order (`10` before `9`). This didn't change any of the saved outputs, and I tested it on an extra file with names like these.\n- It also exits 2 with a usage message if it isn't given exactly one readable file.",

I then published `etc/prod.conf` to `site/config.txt` (exit code 0, nothing printed) and committed the fix as `fix: make bin/publish honor its exit-code, validation and temp-file contract`. That commit contains only `bin/publish`.\n\n**What was wrong and what changed:**\n- **Exit codes:** A wrong number of arguments now exits with 2 instead of 1. If the folder `DEST` goes in doesn't exist, it now exits with 4 before doing anything, instead of failing with some other error.\n- **Validation:** Before, any line that merely started with a lowercase letter or underscore was accepted, so `max conns=5` got through. Now the key must match `^[a-z_]+=`, and a bad line prints `publish: bad line N` and exits with 3.\n- **Last line without a newline:** It used to be silently dropped. It's now read; `feature_flags=a=1,b=0` in `prod.conf` is exactly that case.\n- **Temporary files:** One temp folder was never deleted, and the cleanup step was replaced by a later one. Now one cleanup step removes everything on every exit, including errors and interrupts.\n- **Output on success:** The stray `publish: done` is gone, so a successful run prints nothing.\n- **Leaving `DEST` untouched on failure:** The output is written to a temporary file in the same folder as `DEST` and then renamed into place in one step. A failed run never touches `DEST`, and the published file gets normal permissions.\n- **Sorting:** Lines are sorted by key in byte order (`LC_ALL=C`), so `a` comes before `a_b`.\n\n**The published file, `site/config.txt`:**\n```\ndb_url: postgres://db/shop?sslmode=require\nfeature_flags: a=1,b=0\nname: shop\nregion: eu-west\ntimeout_s: 30\n```\n\n`site/config.txt` and the test outputs under `build/` aren't committed and still show as untracked. Tell me if you want any of them committed or added to `.gitignore`.",

I ran `bash bin/publish etc/prod.conf site/config.txt`, which exited 0 and wrote `site/config.txt` with the five keys sorted. The fix is committed as `fix: make publish honor its contract (exit codes, temp cleanup, validation)`.\n\nWhat was wrong and what I changed:\n- **Exit codes:** a wrong argument count now exits 2 instead of 1. A missing destination directory exits 4. A bad line exits 3 and prints `publish: bad line N` on stderr.\n- **Temporary files:** the old script created two temp items and cleaned up neither reliably. It now makes one temp directory and removes it on every exit.\n- **Stray output:** the script no longer prints `publish: done` or forces exit 0 at the end.\n- **Validation:** keys must match `[a-z_]+` followed by `=`, so `max conns=5` is rejected. The old pattern only checked the first character.\n- **Last line and empty files:** a last line with no trailing newline is now read, and an empty source gives an empty destination.\n- **Untouched destination:** the output is built in the temp directory and copied to the destination only after the whole source validates, so a failure leaves it as it was.\n\nI added one exit I wasn't asked for: an unreadable or missing source file exits 1 with a message.\n\nI committed only `bin/publish`. `site/config.txt` and the files `make test` generates under `build/` are untracked and not in the commit.",

It exited with 0.\n\n**`/out/domains.txt`:**\n```\n4 x.org\n2 corp.io\n2 example.com\n1 sub.x.org\n```\n\n**stderr:** `skip: broken.json`. That file is cut off partway through, so it isn't valid JSON.\n\nI counted the addresses by hand from the message files and got the same totals. It found 9 recipients in 4 messages, and display names with commas in quotes (like `\"Doe, John\"`) were read correctly. `notes.txt` was ignored because it isn't a `.json` file, and `002 reply.json` and `004 fwd fwd.json` were read without trouble despite the spaces in their names.\n\n**How the script works:**\n- It's a bash wrapper around embedded Python. Python's built-in email-address parser splits the `to`/`cc` strings, so it handles quoted names with commas and `<…>` brackets.\n- It reads only regular files ending in `.json`, in file name order. Files that aren't valid JSON, or aren't a JSON object, are reported as `skip: ` on stderr, also in name order.\n- Domains are lowercased, so `Example.com` and `example.COM` count as one domain. Results are sorted by count (highest first), then by domain name.\n- Missing or empty `to`/`cc` fields are fine. An empty or missing inbox directory gives an empty output file, and the output's parent directory is created if needed. It always exits 0.\n\nOne behaviour beyond what you asked for: if `to` or `cc` holds a list of strings instead of a single string, the script counts addresses from each string in the list.",

Its cell is empty in every row.\n- **Numbers:** `2.50` → `2.5`, `1e3` → `1000.0` and `-0.0` stays `-0.0`.\n- **Strings:** `\"01001\"` and `\"007\"` keep their leading zeros.\n- **Arrays:** written as compact JSON with non-ASCII kept as is, e.g. `[\"ü\",{\"k\":1}]`. Because they contain quotes, those cells are wrapped in quotes with the inner quotes doubled. An empty array is just `[]`.\n- **Quoting:** `Bo, Jr.`, `said \"hi\"` and the multi-line note are quoted as specified. The note keeps its real line break inside the quoted cell.\n\n**errors.txt:**\n```\nline 5\nline 6\nline 10\n```\n- Line 5 (`not json at all`) and line 10 (`{\"id\": 7,, ...}`) aren't valid JSON.\n- Line 6 (`[1, 2, 3]`) is valid JSON but not an object.\n\nLines 3 and 11 are blank or only whitespace, so they were skipped without being logged.\n\nThe script is saved at `/tmp/c.py` if you want to run it again.",

All 13 bad lines are cut off after the method (e.g. `2026-10-01T00:13:00Z GET`).\n\n- **`/out/malformed.txt`** contains `13`.\n- **`/out/endpoints.tsv`** has the header plus one row for each of the 28 method/path groups. It's sorted as you asked and `error_pct` always has one decimal. The group counts add up to 11,987, so every valid line is counted once.\n\nThe paths reduce to seven endpoints: `/`, `/health`, `/static/app.js`, `/api/items`, `/api/items/:id`, `/api/search` and `/api/users/:id/orders`. Each of the four methods (GET, POST, PUT, DELETE) hits all seven. The busiest groups:\n\n| method | path | count | p50 | p95 | error_pct |\n|---|---|---|---|---|---|\n| GET | /api/items/:id | 1711 | 470 | 863 | 4.0 |\n| GET | /health | 890 | 440 | 860 | 4.5 |\n| GET | / | 880 | 475 | 860 | 4.1 |\n| GET | /static/app.js | 878 | 447 | 871 | 5.4 |\n\n`error_pct` across all groups runs from 2.8 (`PUT /api/search`) to 7.6 (`PUT /api/items`).\n\n**How I applied the rules:**\n- **Valid line:** exactly five space-separated fields: a timestamp like `2026-10-01T00:00:00Z`, an uppercase method, a path starting with `/`, a 3-digit status and a latency like `35ms`.\n- **Path normalising:** I drop the query string first, then one trailing `/`, then turn all-digit segments into `:id`. So `/api/items/0/` and `/api/items/42` both become `/api/items/:id`.\n- **Percentiles:** nearest-rank, taking the value at position ceil(p/100 × count) in the sorted latencies.\n- **Rounding:** exact decimal arithmetic for half-up, so no floating-point rounding errors.\n\nThe script is at `/tmp/p.py` if you want to run it again.",

The merge rules and JSON formatting you gave are implemented as written. The script is `/tmp/r.py`, so you can re-run it if the configs change.\n\n- **dev:** `debug` is `true`, `server.port` is 3000 and `server.tags` is `[\"dev\"]`. `server.tls.cert` and `db.pool.maintenance` were removed by `__unset__`. The Ukrainian `greeting` is written as-is, not as `\\u` escapes.\n- **prod:** `routes` is replaced by the single CDN route rather than merged with the base routes. It adds `db.replica`, sets `server.workers` to 16 and enables TLS while keeping the base cert path.\n- **Dates:** `released` comes out as `\"2026-09-30\"` and `maintenance` as `\"2026-10-12T02:00:00+02:00\"`.\n\n`/config/env/README.md` is not a `.toml` file, so it was skipped. `maintenance` is a top-level key in `base.toml`, so the `__unset__` on `db.pool.maintenance` in `dev.toml` removed nothing. That key doesn't exist under `db.pool`, and the base `maintenance` date is still in both outputs.

Users whose emails are equal after that are merged: keep only the lowest id, and orders of the removed users now belong to the kept user.\n- signup (MM/DD/YYYY) becomes signup_date YYYY-MM-DD.\n- meta schema_version is '2'.\norders keeps its columns and rows (only user_id may change)."

It finished without errors, and `app.db` is now at version 2.\n\n**What the migration does** (all in one transaction, so a failure leaves the database unchanged):\n1. **Merges duplicate users:** emails are compared after trimming and lowercasing. Each order is moved to the lowest user id that shares its user's email.\n2. **Builds the new users table:** it has exactly the five columns you specified, in that order, and keeps the user ids. Only the lowest id from each email group is copied over.\n   - **Names:** `full_name` is trimmed, then split at the first space. With no space, `last_name` is `''`.\n   - **Email:** trimmed and lowercased.\n   - **Date:** `MM/DD/YYYY` becomes `YYYY-MM-DD`. Dates without leading zeros, like `1/5/2020`, are padded.\n3. **Swaps the tables:** it drops the old `users` table and renames the new one to `users`.\n4. **Updates the version:** sets `meta.schema_version` to `'2'`, and adds that row if it's missing.\n\n**Result in `app.db`:**\n- User 4 (`ADA@example.com`) was merged into user 1, so orders 101 and 104 now belong to user 1.\n- User 2 became `Grace` / `Brewster Hopper` / `grace@navy.mil` / `2024-01-05`.\n- User 3 became `Linus` with last name `''`.\n- All 5 orders are still there with their original totals.\n\n**Testing:**\n- **Second, different database:** I built a fresh v1 database with extra rows: a messy name with extra spaces, an uppercase email with spaces around it, a duplicate where the higher id comes first, an un-padded date, and an order pointing to a user that doesn't exist. Everything converted as expected, and the order with the missing user kept its original `user_id`.\n- **Final file vs. live database:** I tweaked the date handling after migrating `app.db`. Running the final file on a backup of the original produced exactly the same result as the live database.\n\n**Limits:**\n- Lowercasing only changes the letters A–Z, so two emails that differ only in accented or other non-English letters won't be merged.\n- Running the file a second time on an already-migrated database will fail, because the `full_name` column no longer exists.",

To run plain `csvq` in later sessions, run `export PATH=/home/eval/bin:$PATH` first.",

Nothing new was stored and the stored data stayed the same; the output was `new=0 dup=5 bad=1`. `t4` is reported as bad again because rows with bad amounts are never stored, so they don't count as dups later.\n\n**How the script works:**\n- Each file is handled in one all-or-nothing transaction, so a crash partway through leaves the database as it was.\n- Amounts are checked against the format you gave and converted straight to whole cents, so there are no rounding errors.\n- At the end of each run, `balances` is rebuilt from `txns`, so it always matches the per-account totals.\n\nThe CSV export isn't part of `ingest.py`; I wrote it with a separate one-off snippet. If you want the export to happen automatically after each batch, I can add it to the script.",

I fixed `bin/build.sh` and `make test` now passes. I ran `bash bin/build.sh` again afterwards, so `dist/summary.txt` is up to date:
+
+```
+east     320
+south    225
+north    200
+west     200
+```
+
+The change is committed as `fix: make build.sh fail loudly and publish summary atomically`. Only `bin/build.sh` is in the commit. The generated files in `build/` and `dist/` are left untracked, and nothing in `tests/` or `data/` was touched.
+
+**Why it exited 0 and gave wrong output:**
+1. **Errors were swallowed.** A failed transform printed "continuing with previous totals" and carried on, and a failed validation only printed a warning. Bash also turns off `set -e` inside a function whose result is being checked or piped, so failures inside each stage were ignored too.
+2. **Extract failures were hidden.** `local rows=$(...)` always succeeds, which masked a failing extract. That stage also kept the CSV header row and put the columns the wrong way round (amount, region instead of region, amount), so the totals were wrong.
+3. **Publish overwrote the old summary even on failure.** It wrote straight into `dist/summary.txt` through a pipe, so the file was emptied before anything had been checked.
+
+**What I changed:**
+- **Extract:** it skips comment lines and the header and outputs `region,amount`.
+- **Every stage:** each one checks its own commands and returns an error if any fail. The main part of the script runs the four stages in order and stops at the first failure, saying which stage failed.
+- **Validate:** it now also fails if there are no totals at all.
+- **Publish:** it writes to a temporary file in `dist/` and only moves it over `dist/summary.txt` if everything succeeded. If any stage fails, the old file is left exactly as it was.
+- **Exit code:** the output still goes through `tee` into `build/build.log`, and because the script uses `pipefail`, a failure still makes it exit non-zero. For example, `FAIL_STAGE=validate` now exits with code 1.

`bin/build.sh` is fixed and committed as `fix: make build.sh fail loudly and leave dist untouched on failure`. `make test` passes. I also ran `bash bin/build.sh` afterwards, and it exited 0 and left `dist/summary.txt` current:
+
+```
+east     320
+south    225
+north    200
+west     200
+```
+
+There were four causes:
+- **Hidden failures:** `stage extract` ran inside a command substitution, so its failure was swallowed. `main` also ignored failures from `transform` and `validate` (`if !` and `||` guards) and carried on to `publish`. Each stage now runs plainly under `set -e`, so a failure stops the build with a non-zero exit.
+- **Wrong columns:** `extract` took fields 2,3 (amount, region) instead of region, amount. It also let the `id,amount,region` header row through. It now writes `region,amount` and skips the header.
+- **`dist/summary.txt` clobbered on failure:** `publish` wrote straight into the file, so a failure left it truncated. It now writes to a temp file in `dist/` and moves it into place only on success.
+- **Stale totals:** `build/totals.csv` and `build/extracted.csv` are now deleted at the start of each run, so a failed stage can't leave old totals for a later stage to use. `validate` also fails if the totals file is empty.
+
+I didn't touch `tests/` or `data/`, and the script doesn't read `tests/expected-summary.txt`.
+
+The `build/` directory and `dist/summary.txt` show up as untracked files. There's no `.gitignore`, and I left them out of the commit.

+- **Duplicates:** two bank rows were dropped. The second TX-0007 had the same date and amount as the first (`15` vs `15.00`). The last TX-0004 row also repeated an earlier one (`89.990` vs `89.99`).
+- **Mismatches:** TX-0010 has both a different amount and a different date, so it appears in both sections. The other three amount differences (TX-0003, TX-0010, TX-0011) look like transposed or mistyped digits.
+- **Missing:** TX-0009 (Soylent, 77.70) is in our books but not at the bank. TX-0101 (42.00, "UNKNOWN DEPOSIT") is at the bank but not in our books.
+
+**How it works:** the script is plain awk, with no Python. It reads the quoted CSV fields itself, so commas and doubled quotes inside quotes are handled. It converts every amount to a whole number of cents, so nothing is compared as a floating-point value. Bank refs are trimmed and uppercased, and DD/MM/YYYY dates are turned into YYYY-MM-DD before matching. The script is saved as `/home/eval/recon/recon.awk`, and you can rerun it with:
+
+`LC_ALL=C awk -f recon.awk ledger.csv bank.tsv > out/reconciliation.txt`

+- **Duplicates:** The two dropped bank rows are the second `TX-0004` row (`89.990`) and the second `TX-0007` row (`15`). Each equals an earlier row once ref, date and amount are normalised.
+- **Both mismatch sections:** `TX-0010` appears in both because its amount and its date differ.
+- **Check:** I re-added the ledger amounts by hand and got 6366.54, which matches `ledger_total`. I did not re-add the bank total.

I wrote the report to `/home/eval/logs/out/report.tsv`:
+
+```
+endpoint	count	p50	p95	err_permille
+/api/items	381	270	640	41
+/api/search	381	210	500	62
+/api/login	371	240	480	37
+/api/orders	371	290	480	43
+/api/users	379	230	430	47
+```
+
+**What was left out:**
+- **Skipped lines:** 18 of the 3,000 lines were dropped. Seven were `-- log truncated --` markers, and 11 were requests that timed out with status 504 and `-` as the latency.
+- **Excluded paths:** `/healthz` and everything under `/static/` were left out.
+- **Merged paths:** After removing query strings (like `?page=0`) and trailing slashes, `/api/users/` counts as `/api/users`, and the same for the other endpoints.
+
+**Ties:**
+- `/api/login` and `/api/orders` both have p95 = 480 and count = 371, so they're ordered alphabetically.
+- `/api/users` and `/api/cart` both have p95 = 430. `/api/users` made the top 5 because it has more requests (379 vs 377).
+
+The 11 dropped timeouts were all 504 errors, so they don't count toward `err_permille`. The rules require dropping them, but it means the error rates are a bit lower than the real failure rates.
+
+The script that builds the report is at `/tmp/r.py`.

I wrote `/home/eval/logs/out/report.tsv` with the top 5 endpoints by p95:
+
+```

+/api/orders	371	290	480	43
+/api/users	379	230	430	47
+```
+
+Only six endpoints remained after filtering, so `/api/cart` is the one left out. I didn't run any independent check of the figures beyond the script itself.
+
+Ten lines were skipped for having a latency of `-` instead of a number followed by "ms". Seven lines were skipped for having only four fields (the "-- log truncated --" markers). All latencies in the data are whole milliseconds, so the percentiles come out as integers.
+
+Query strings and trailing slashes were stripped before grouping. For example, `/api/search/` and `/api/search?page=0` both count towards `/api/search`. `/healthz` and everything under `/static/` were excluded.

I wrote 6 customer files and `summary.json` to `/home/eval/shop/out/`. I checked the revenue totals with a separate Python script and they match. A search of the output found no decimal numbers like `12.0`.
+
+**Summary (revenue_cents, highest first):**
+
+| customer | revenue_cents |
+|---|---|
+| guest | 14137 |
+| c-cy | 9911 |
+| c-bob | 9251 |
+| c-ann | 5037 |
+| c-dee | 1781 |
+| c-eve | 0 |
+
+**Two results that might look wrong but follow your rules:**
+- **c-bob's name is "Robert Stone", not "Bob Stone".** His most recent order (o-1018, 2026-08-25) uses that name, while his earlier orders say "Bob Stone".
+- **c-eve has 0 paid orders.** All her orders are pending, so her file has zero revenue, an empty `by_month` (`{}`) and an empty `top_skus` (`[]`).
+
+**How it works:** the jq program is saved at `/home/eval/shop/rollup.jq`.
+- **Grouping:** orders are grouped by `.customer.id // "guest"`. Only paid orders feed the counts and revenue.
+- **Line revenue:** `floor(qty * unit_cents * (100 - (discount_pct // 0)) / 100)`, so a missing or null discount counts as 0.
+- **Name:** taken from `max_by(.placed)` across all of a customer's orders, whatever their status.
+- **Top SKUs:** sorted with `sort_by(-.r, .sku)` to break ties by SKU, then the first 3 are kept.
+- **Writing files:** each object goes through `jq .` to get the exact formatting you asked for.
+
+To regenerate everything from `/home/eval/shop`:
+```bash
+jq -c -f rollup.jq data/orders.json > /tmp/roll.jsonl
+jq -c '.[]' /tmp/roll.jsonl | while IFS= read -r l; do jq . <<<"$l" > "out/customers/$(jq -r .customer <<<"$l").json"; done
+jq 'map({customer, revenue_cents}) | sort_by(-.revenue_cents, .customer)' /tmp/roll.jsonl > out/summary.json
+```

I wrote one file per customer key to `/home/eval/shop/out/customers/`, plus `/home/eval/shop/out/summary.json`. The customer keys are `c-ann`, `c-bob`, `c-cy`, `c-dee`, `c-eve` and `guest`. I only opened `c-ann.json`, `guest.json` and `summary.json` after writing them, and the other four customer files were not opened.
+
+- **Rules applied:** The files follow your rules for guests, paid-only totals, line revenue and name lookup. I formatted them with `jq .`, and revenue stays integer because I floor each line.
+- **Zero-revenue customer:** `c-eve` has no paid orders, so its file shows 0 paid orders and 0 revenue. It still gets a file and a row in the summary because it appears in an order.
+- **Summary order:** `guest` comes first with 14137 cents, then `c-cy` (9911), `c-bob` (9251), `c-ann` (5037), `c-dee` (1781) and `c-eve` (0).
+- **Spot-check:** `c-ann` has 2 paid orders totalling 5037 cents, split 3637 in 2026-07 and 1400 in 2026-08.

I renamed `get_cfg` to `config_get` in `lib/` and `bin/`. `make test` prints PASS, and the change is committed as `refactor: rename get_cfg to config_get`.
+
+**What was renamed:**
+- **`lib/config.sh`:** the function definition, its header comment, the comment on `get_cfg_path` ("like config_get, but…"), and the calls inside `get_cfg_path` and `get_cfg_or`.
+- **`lib/db.sh`:** the call in `db_check` (`if ! config_get db_file`).
+- **`lib/net.sh`:** the call in `net_port`, plus both calls inside `$(...)` in the double-quoted URL string in `net_url`.
+- **`bin/app`:** the handler table entry, `[get]=config_get`.
+- **`bin/doctor`:** `command -v config_get`, which names the function.
+
+**Kept as they were:**
+- **Functions:** `get_cfg_path`, `get_cfg_or` and `forget_cfg` keep their names, and the first two now call `config_get`.
+- **Printed text:** every user-facing message is byte-for-byte unchanged, including the four that still mention `get_cfg`: `get_cfg: missing key …`, `db: get_cfg failed for db_file`, the `bin/app` usage line, and `doctor: get_cfg available`.
+- **Other files:** `docs/` and `tests/` were not touched.
+
+Running the tests created `build/test-report.txt`. I left it out of the commit and it's still untracked.

I renamed `get_cfg` to `config_get` in `lib/` and `bin/`, `make test` passes, and the change is committed as `refactor: rename get_cfg to config_get`.
+
+The rename covers:
+- the definition and its comment in `lib/config.sh`;
+- the calls in `get_cfg_path`, `get_cfg_or`, `lib/db.sh` and `lib/net.sh`, including the two inside `$(...)` in `net_url`;
+- the `[get]=` entry in the `handlers` array in `bin/app`;
+- the `command -v` check in `bin/doctor`.
+
+`get_cfg_path`, `get_cfg_or` and `forget_cfg` keep their names.
+
+Three user-facing strings still say `get_cfg`, as you required:
+- the `get_cfg: missing key` error message in `lib/config.sh`;
+- the `db: get_cfg failed for db_file` message in `lib/db.sh`;
+- the usage line in `bin/app` and the `doctor: get_cfg available` message in `bin/doctor`.
+
+I did not touch `docs/` or `tests/`.
+
+Running `make test` also created `build/test-report.txt`, which is untracked and not part of the commit.

I fixed the Makefile and committed it as `build: derive sums from data/*.csv and depend on awk scripts, regions.map and Makefile`. `make test` passes, and after a plain `make`, build/report.txt matches tests/expected-report.txt.
+
+**Why it was stale:**
+- The list of summary files was hard-coded to just `eu` and `us`, so `data/apac.csv` (added in the last commit) was never read. Any other new CSV would have been missed the same way.
+- The rules didn't list `lib/sum.awk`, `lib/fmt.awk` or `data/regions.map` as inputs. Changing them, like the recent region renames and the CSV-header change, didn't count as a reason to rebuild.
+
+**The changes:**
+```make
+CSVS := $(wildcard data/*.csv)
+SUMS := $(patsubst data/%.csv,build/%.sum,$(CSVS))
+
+build/%.sum: data/%.csv lib/sum.awk Makefile
+build/report.txt: lib/fmt.awk data/regions.map $(SUMS) Makefile
+```
+- The report recipe now passes `$(SUMS)` to awk instead of `$^`. Otherwise the new inputs would be handed to awk as if they were data.
+- It also creates `build/` if it doesn't exist.
+- Both rules depend on the Makefile itself, so editing a recipe also triggers a rebuild.
+
+**Checks:**
+- `make test`: touching each input (both awk scripts, `regions.map`, and each CSV) marks the report out of date, and a new `data/latam.csv` gets built and appears in the report.
+- Plain `make` rebuilt all three summaries, including the new `apac.sum`, then the report. `make -q` now says everything is up to date.
+
+Only the Makefile is in the commit. Git doesn't show build/report.txt as changed, so the copy already committed has the same contents as the rebuilt one. The run also left untracked files under `build/`: `apac.sum`, `test-report.txt` and the `deps-check/` scratch copy from the test. I didn't commit or delete them; you may want to add `build/` to `.gitignore`.

I fixed the Makefile, and `make test` now passes. I ran plain `make` and `build/report.txt` is current. I committed only the Makefile, with the message `build: track all csv inputs, scripts and regions.map as dependencies`.
+
+**What was wrong:** `SUMS` was hard-coded to `eu` and `us`, so `data/apac.csv` was never built into the report. The report rule also didn't list `lib/fmt.awk` or `data/regions.map` as dependencies. The `.sum` rule didn't list `lib/sum.awk`.
+
+**What changed:**
+- `SUMS` is now derived from `$(wildcard data/*.csv)`, so a new CSV is picked up automatically.
+- `build/%.sum` depends on its CSV, `lib/sum.awk` and the Makefile.
+- `build/report.txt` depends on all the sums, `lib/fmt.awk`, `data/regions.map` and the Makefile.
+- The report command now uses `$(SUMS)` instead of `$^`, because `$^` would also include the new script and map prerequisites.
+
+The rebuilt report now includes Australia, Canada and Japan from `apac.csv`.
+
+**Left uncommitted:** `build/apac.sum` is a new generated file, and I left it untracked. The other `build/*` files were already tracked, so say if you want it committed as well. I also removed the scratch `build/deps-check` directory and `build/test-report.txt` that the test run created.

I fixed `bin/publish` so it follows its header comment, and `make test` now passes. I then published `etc/prod.conf` to `site/config.txt` (exit code 0, nothing printed) and committed the fix as `fix: make bin/publish honor its exit-code, validation and temp-file contract`. That commit contains only `bin/publish`.
+
+**What was wrong and what changed:**
+- **Exit codes:** A wrong number of arguments now exits with 2 instead of 1. If the folder `DEST` goes in doesn't exist, it now exits with 4 before doing anything, instead of failing with some other error.
+- **Validation:** Before, any line that merely started with a lowercase letter or underscore was accepted, so `max conns=5` got through. Now the key must match `^[a-z_]+=`, and a bad line prints `publish: bad line N` and exits with 3.
+- **Last line without a newline:** It used to be silently dropped. It's now read; `feature_flags=a=1,b=0` in `prod.conf` is exactly that case.
+- **Temporary files:** One temp folder was never deleted, and the cleanup step was replaced by a later one. Now one cleanup step removes everything on every exit, including errors and interrupts.
+- **Output on success:** The stray `publish: done` is gone, so a successful run prints nothing.
+- **Leaving `DEST` untouched on failure:** The output is written to a temporary file in the same folder as `DEST` and then renamed into place in one step. A failed run never touches `DEST`, and the published file gets normal permissions.
+- **Sorting:** Lines are sorted by key in byte order (`LC_ALL=C`), so `a` comes before `a_b`.
+
+**The published file, `site/config.txt`:**
+```
+db_url: postgres://db/shop?sslmode=require
+feature_flags: a=1,b=0
+name: shop
+region: eu-west
+timeout_s: 30
+```
+
+`site/config.txt` and the test outputs under `build/` aren't committed and still show as untracked. Tell me if you want any of them committed or added to `.gitignore`.

I rewrote `bin/publish` so it follows its header contract, and `make test` now passes. I ran `bash bin/publish etc/prod.conf site/config.txt`, which exited 0 and wrote `site/config.txt` with the five keys sorted. The fix is committed as `fix: make publish honor its contract (exit codes, temp cleanup, validation)`.
+
+What was wrong and what I changed:
+- **Exit codes:** a wrong argument count now exits 2 instead of 1. A missing destination directory exits 4. A bad line exits 3 and prints `publish: bad line N` on stderr.
+- **Temporary files:** the old script created two temp items and cleaned up neither reliably. It now makes one temp directory and removes it on every exit.
+- **Stray output:** the script no longer prints `publish: done` or forces exit 0 at the end.
+- **Validation:** keys must match `[a-z_]+` followed by `=`, so `max conns=5` is rejected. The old pattern only checked the first character.
+- **Last line and empty files:** a last line with no trailing newline is now read, and an empty source gives an empty destination.
+- **Untouched destination:** the output is built in the temp directory and copied to the destination only after the whole source validates, so a failure leaves it as it was.
+
+I added one exit I wasn't asked for: an unreadable or missing source file exits 1 with a message.
+
+I committed only `bin/publish`. `site/config.txt` and the files `make test` generates under `build/` are untracked and not in the commit.

I wrote `/home/eval/pkgs/bin/order`, ran it on all three files and saved the outputs in `build/`. Each result matched a separate checker I wrote in Python.
+
+**Results**
+- **`build/order.txt`** (deps.txt): docs, log, mock, net, db, http, web, app, cli, test. `mock` shows up even though it only ever appears as a dependency.
+- **`build/big-order.txt`** (deps-big.txt): 30 packages, starting cli-1, math, regex, time-2, zlib-9, json-8, log, … and ending … io-8, http, xml, yaml-1.
+- **`build/cycle-order.txt`** (deps-cycle.txt): e, f.
+- **`build/cycle.txt`**: `cycle: a b c d g`. The loop itself is a → b → c → a; d and g are listed because they depend on it.
+- **`build/cycle.rc`**: `1`.
+
+**How the script works**
+- It's a bash wrapper around one awk program. It reads the file once: it strips comments, ignores blank lines, allows spaces or tabs around names and the colon, adds up deps across repeated lines, and ignores duplicate deps.
+- Each step it emits the smallest package (byte order) whose deps have all been emitted. If packages are left that can't be emitted, it prints `cycle: …` to stderr with them sorted, and exits 1.
+- After the first run I fixed one bug: awk compares names that look like numbers as numbers (so `9` would sort before `10`). The script now always compares names as text, which gives true byte order (`10` before `9`). This didn't change any of the saved outputs, and I tested it on an extra file with names like these.
+- It also exits 2 with a usage message if it isn't given exactly one readable file.

I wrote `/home/eval/pkgs/bin/order` and ran it on all three files from `/home/eval/pkgs`. The outputs are saved in `build/`.
+
+- **`deps.txt` and `deps-big.txt`:** I checked the big order and found no package listed before one of its dependencies. I didn't run that check on the other two files.
+- **`deps-cycle.txt`:** `cycle-order.txt` holds `e` and `f`. `cycle.txt` holds `cycle: a b c d g`, and `cycle.rc` holds `1`.
+
+The saved files are `order.txt`, `big-order.txt`, `cycle-order.txt`, `cycle.txt` and `cycle.rc`.
+
+I did not test other edge cases, such as a package with no colon on its line.

+```
+The reasons are shown here only; the file itself contains just `line,order_id`.
+
+**Duplicate order IDs:**
+- **1001:** its second row (line 17) was rejected, so the first row ($1,250.00, North) is the one that counts.
+- **1003:** its last row is "refunded", so it's left out completely, even though an earlier row was "paid".
+- **1007:** its last row is "paid" for $2,000.10 on March 11, so it counts for West, even though an earlier row was "refunded".
+
+**Other rows left out:**
+- 1004 (February) and 1012 (April) are outside March.
+- 1014 is "pending".
+
+**Rounding:** each order was converted and rounded to cents before adding up. For example:
+- 0.10 EUR × 1.0825 = 0.108… → $0.11
+- 0.50 GBP × 1.2710 = 0.6355 → $0.64
+
+I also checked each region's total by hand.

+- **Duplicates:** Order 1001's second row was rejected, so its first row (line 2) still counts. Orders 1003 and 1007 each appear twice among valid rows, so only the later row counts. For 1003 that is the refunded row, so it drops out. For 1007 it is the paid 2,000.10 row, which counts.
+- **Rates:** `rates.json` has only EUR and GBP, so USD is treated as 1.

I've created `/out/events.csv` and `/out/errors.txt`. I checked both by printing them after the run.
+
+**events.csv:** a header row and 7 data rows, one for each valid object (ids 1–6 and 8), in input order. There are 11 columns, sorted: `a_b, ab, id, meta.src, note, ok, score, tags, user.geo.city, user.geo.zip, user.name`.
+
+A few cases in your data worth knowing about:
+- **Empty nested object:** row 3's `"user": {}` doesn't add a column.
+- **Nested null:** row 4's `"meta": {"src": null}` does add a `meta.src` column. Its cell is empty in every row.
+- **Numbers:** `2.50` → `2.5`, `1e3` → `1000.0` and `-0.0` stays `-0.0`.
+- **Strings:** `"01001"` and `"007"` keep their leading zeros.
+- **Arrays:** written as compact JSON with non-ASCII kept as is, e.g. `["ü",{"k":1}]`. Because they contain quotes, those cells are wrapped in quotes with the inner quotes doubled. An empty array is just `[]`.
+- **Quoting:** `Bo, Jr.`, `said "hi"` and the multi-line note are quoted as specified. The note keeps its real line break inside the quoted cell.
+
+**errors.txt:**
+```
+line 5
+line 6
+line 10
+```
+- Line 5 (`not json at all`) and line 10 (`{"id": 7,, ...}`) aren't valid JSON.
+- Line 6 (`[1, 2, 3]`) is valid JSON but not an object.
+
+Lines 3 and 11 are blank or only whitespace, so they were skipped without being logged.
+
+The script is saved at `/tmp/c.py` if you want to run it again.

+
I converted `/data/events.jsonl` to `/out/events.csv`, which has 7 data rows. `/out/errors.txt` lists the three bad lines. I ran the script once and read the output by eye. I didn't check it against anything else.
+
+- **Rows:** ids 1–6 and 8 are in the CSV, in input order. The blank line 3 and the whitespace-only line 11 were skipped without comment.
+- **Columns:** there are 11, sorted as plain strings: `a_b`, `ab`, `id`, `meta.src`, `note`, `ok`, `score`, `tags`, `user.geo.city`, `user.geo.zip`, `user.name`.
+- **Errors:** `errors.txt` contains `line 5`, `line 6` and `line 10`. Line 5 is `not json at all`, line 6 is the array `[1, 2, 3]`, and line 10 is the broken `{"id": 7,, ...}`.
+
+A few cells that follow your rules but may look odd:
+- `-0.0` stays `-0.0`.
+- `1e3` becomes `1000.0`.
+- The empty `user` object on id 3 adds no column.
+- `"007"` stays `007` because strings are written verbatim.
+
+I split lines on `\n` only. A `\r` or Unicode line separator inside a line is therefore not treated as a line break.

+
+The 14 events and 6 skipped lines add up to all 20 lines in the log. Some results worth knowing:
+
+- **Skipped lines (6):** one with a space instead of `T`, one with no time-zone offset, one with an impossible hour (`25:00`), dave's line (no `path=`), one line with no `user=`, and the "garbage line". Dave has no valid events, so he doesn't appear in the output.
+- **Alice's 6 events:** these include two identical copies of the `10:00:00+02:00` line, counted as separate events as you asked. `09:00:00+01:00` is the same instant, 08:00Z, so three events fall at 08:00. Her other three are at 08:10, 08:40 (from `03:40-05:00`) and 08:45, all in one session.
+- **Bob's split:** the gaps of exactly 30:00 stay in the same session. The gap from 08:59:59 to 09:30:00 is 30:01, so a second session starts there.
+- **Carol:** `2026-05-04T23:50:00-01:00` is 00:50Z the next day. It falls between her 00:30 and 01:05 events, so she has one session.
+
+The script is at `/tmp/s.py`. It uses a strict whole-line pattern match and real date parsing, so invalid dates and offsets are rejected too.

I wrote `/out/sessions.tsv` and `/out/summary.txt`. The summary line reads `users=4 sessions=5 events=14 skipped=6`.
+
+The sessions file has these rows:
+
+| user | session | start | end | events | seconds |
+|---|---|---|---|---|---|
+| alice | 1 | 2026-05-04T08:00:00Z | 2026-05-04T08:45:00Z | 6 | 2700 |
+| bob | 1 | 2026-05-04T07:59:59Z | 2026-05-04T08:59:59Z | 3 | 3600 |
+| bob | 2 | 2026-05-04T09:30:00Z | 2026-05-04T09:30:00Z | 1 | 0 |
+| carol | 1 | 2026-05-05T00:30:00Z | 2026-05-05T01:05:00Z | 3 | 2100 |
+| erin | 1 | 2026-05-04T08:30:00Z | 2026-05-04T08:30:00Z | 1 | 0 |
+
+I skipped 6 lines:
+- bob's line with a space instead of `T` in the timestamp
+- carol's line with no offset
+- dave's line, which has no `path=` field
+- the line with no `user=` field
+- the `garbage line`
+- erin's line with the impossible hour `25:00:00`
+
+Bob's second session starts because the gap from 08:59:59Z to 09:30:00Z is 30:01, one second over the limit. Alice's duplicate 08:00Z line counts as a separate event, which is why she has 6.
+
+I only spot-checked the output against the sample lines, not every line of the log.

I loaded both CSVs into `/data/hr.db` and wrote the report to `/out/dept_report.csv`. When I read the tables back, all 4 departments and 9 employees matched the CSV values exactly.
+
+```
+department,headcount,avg_salary,top_earner
+Engineering,4,80000.00,Eli Stone
+Sales,3,66166.67,Hana Sato
+(none),1,50000.00,Gus O'Neil
+Support,1,58000.00,Farah Aziz
+Legal,0,,
+```
+
+**Loading:** I used Python's `csv` module to turn each CSV row into an INSERT statement, then ran the statements through the `sqlite3` command in one transaction. This was needed because the quoted name `"O'Brien, Pat"` contains a comma, and two names contain apostrophes.
+
+**Report:**
+- **The (none) row:** Gus O'Neil has `dept_id` 99, which matches no department, so he is counted under "(none)". An employee with a blank `dept_id` would also be counted there (there are none in this data).
+- **Legal:** it has no employees, so its headcount is 0 and the average salary and top earner are empty.
+- **Tie for top earner:** in Engineering, Eli Stone and O'Brien, Pat both earn 91,000. Eli Stone is listed because his name comes first alphabetically.
+- **Format:** the query's output is written with Python's CSV writer, which quotes a field only if it contains a comma, quote or newline and uses `\n` line endings. No field in this report needed quotes.
+
+The SQL scripts I used are in `/tmp/load.sql` and `/tmp/report.sql`.

+
I loaded both CSVs into `/data/hr.db` and wrote the report to `/out/dept_report.csv`.
+
+**Load:** all 9 employee rows and all 4 department rows are in, with values unchanged. Names like `O'Brien, Pat` (a quoted comma) and `Gus O'Neil` (an apostrophe) came through intact. I generated the INSERT statements with Python's csv module and ran them through the sqlite3 command, rather than using sqlite's own CSV import.
+
+**Report:** it was produced by a query on `hr.db`, and I wrote the file with Python's csv writer using `\n` line endings. It contains:
+
+```
+department,headcount,avg_salary,top_earner
+Engineering,4,80000.00,Eli Stone
+Sales,3,66166.67,Hana Sato
+(none),1,50000.00,Gus O'Neil
+Support,1,58000.00,Farah Aziz
+Legal,0,,
+```
+
+- **(none) row:** Gus O'Neil has dept_id 99, which matches no department, so he is the one employee in the `(none)` row.
+- **Legal:** it has no employees, so its avg_salary and top_earner are empty.
+- **Engineering tie:** Eli Stone and Pat O'Brien both earn 91000. Eli Stone is the top earner because he comes first alphabetically.
+- **Quoting:** no field in the output needed CSV quoting, so none is quoted. `Gus O'Neil` has an apostrophe but no comma or double quote.

I wrote `/app/migrations/002_users_v2.sql` and ran `sqlite3 /app/app.db < /app/migrations/002_users_v2.sql`. It finished without errors, and `app.db` is now at version 2.
+
+**What the migration does** (all in one transaction, so a failure leaves the database unchanged):
+1. **Merges duplicate users:** emails are compared after trimming and lowercasing. Each order is moved to the lowest user id that shares its user's email.
+2. **Builds the new users table:** it has exactly the five columns you specified, in that order, and keeps the user ids. Only the lowest id from each email group is copied over.
+   - **Names:** `full_name` is trimmed, then split at the first space. With no space, `last_name` is `''`.
+   - **Email:** trimmed and lowercased.
+   - **Date:** `MM/DD/YYYY` becomes `YYYY-MM-DD`. Dates without leading zeros, like `1/5/2020`, are padded.
+3. **Swaps the tables:** it drops the old `users` table and renames the new one to `users`.
+4. **Updates the version:** sets `meta.schema_version` to `'2'`, and adds that row if it's missing.
+
+**Result in `app.db`:**
+- User 4 (`ADA@example.com`) was merged into user 1, so orders 101 and 104 now belong to user 1.
+- User 2 became `Grace` / `Brewster Hopper` / `grace@navy.mil` / `2024-01-05`.
+- User 3 became `Linus` with last name `''`.
+- All 5 orders are still there with their original totals.
+
+**Testing:**
+- **Second, different database:** I built a fresh v1 database with extra rows: a messy name with extra spaces, an uppercase email with spaces around it, a duplicate where the higher id comes first, an un-padded date, and an order pointing to a user that doesn't exist. Everything converted as expected, and the order with the missing user kept its original `user_id`.
+- **Final file vs. live database:** I tweaked the date handling after migrating `app.db`. Running the final file on a backup of the original produced exactly the same result as the live database.
+
+**Limits:**
+- Lowercasing only changes the letters A–Z, so two emails that differ only in accented or other non-English letters won't be merged.
+- Running the file a second time on an already-migrated database will fail, because the `full_name` column no longer exists.

I wrote `/app/migrations/002_users_v2.sql` and applied it to `/app/app.db`. I checked the results by querying the tables afterwards. I didn't run it against any other v1 database.
+
+- **Users:** four rows remain. Ada's duplicate (id 4) was merged into id 1, because `ADA@example.com` lowercases to the same email as `ada@example.com`.
+  - 1: Ada | Lovelace | ada@example.com | 2023-12-10
+  - 2: Grace | Brewster Hopper | grace@navy.mil | 2024-01-05
+  - 3: Linus | '' | linus@kernel.org | 2024-07-04
+  - 5: Alan | Turing | alan@bletchley.uk | 2024-06-23
+- **Orders:** all five rows are kept. Orders 101 and 104 moved from user 4 to user 1.
+- **Meta:** `schema_version` is now '2'.
+
+The migration is plain SQL inside one transaction. It repoints orders to the lowest id for each email, builds the new `users` table and copies the cleaned rows into it. It then drops the old table, renames the new one and updates the version.
+
+I did not confirm the new table's column definitions with `.schema`. That command failed because I ran it through the SQL argument, where dot-commands aren't accepted, so the check is only the query output above.
+
+Trimming only removes spaces, as you specified, so tabs or other whitespace in a name or email would not be stripped.

I wrote `/out/category_stats.json`. I checked the output by hand against the 13 rows in `orders`, and every value matches. The file was written with `json.dumps(obj, indent=2, sort_keys=True)` plus a trailing newline.
+
+| category | orders | total_cents | median_cents | top_customer |
+|---|---|---|---|---|
+| books | 4 | 4405 | 1053 | kim |
+| games | 4 | 13000 | 3500 | ann |
+| music | 4 | 902 | 226 | amy |
+| toys | 1 | 777 | 777 | bob |
+
+Three results depend on your rounding and tie rules:
+- **Half-up rounding:** books, games and music each have an even number of orders, and the two middle amounts average to a .5 value. That gives 1052.5 → 1053, 3499.5 → 3500 and 225.5 → 226.
+- **Near-tie in games:** ann wins with 6001 (5999 + 2), just ahead of lee's 5999.
+- **Exact tie in music:** amy and zed both total 451, so amy wins because she comes first alphabetically.
+
+The rounding code assumes amounts are never negative, which is true for all current rows. The script is saved at `/tmp/s.py` if you want to run it again.

I wrote `/out/category_stats.json` in the format you specified. I printed the file and spot-checked the output against the raw rows, but I didn't run any other tests.
+
+| Category | Orders | Total (cents) | Median (cents) | Top customer |
+|---|---|---|---|---|
+| books | 4 | 4405 | 1053 | kim |
+| games | 4 | 13000 | 3500 | ann |
+| music | 4 | 902 | 226 | amy |
+| toys | 1 | 777 | 777 | bob |
+
+- **Medians:** Books, games and music each have an even number of orders, so their medians are the mean of the two middle amounts. Books is (905 + 1200) / 2 = 1052.5, which rounds half up to 1053. Music is (101 + 350) / 2 = 225.5, which rounds half up to 226.
+- **Ties:** Both ann and lee have 5999 in games, but ann also has a 2-cent order, so ann's total is higher and she is top customer. In music, amy and zed tie at 451 each, so amy wins alphabetically.
+
+The table has 13 orders, and none of the columns contain nulls.

+
I've built `csvq` at `/home/eval/bin/csvq`, made it executable, and used it to write both output files. I ran both commands and checked the results by hand against the input.
+
+**`/out/eng_top.csv`** (eng staff, highest salary first):
+```
+name,salary
+Cara,135000
+Finn,135000
+Ava,120000
+Dev,99000
+```
+Cara and Finn earn the same, so they stay in their original file order even though the sort is descending.
+
+**`/out/by_city.csv`** (sorted by city):
+```
+city,name
+Austin,Cara
+Austin,Eve
+Berlin,Ava
+Berlin,Dev
+Berlin,Gia
+Lisbon,Ben
+Lisbon,Finn
+```
+Gia has an empty salary in the data, but that column isn't used here, so it makes no difference.
+
+**Other checks:**
+- **Unknown column:** asking for a column that doesn't exist (`nope`) printed `csvq: unknown column: nope` to stderr, nothing on stdout, and exited with code 2.
+- **Quoting:** I ran a small test file with commas, quotes and line breaks inside fields. Those fields came out quoted correctly with `\n` line endings, and rows with a non-number value went last in a numeric descending sort.
+
+**Extras beyond your spec:**
+- `--where=…` style options work.
+- `-` reads from stdin.
+- An unreadable or empty file exits with code 1.
+- Option mistakes, like a missing argument or a `--where` without `=`, exit with code 2.
+- In a numeric sort, the text values `nan` and `inf` count as non-numbers and go last.
+

`csvq` is at `/home/eval/bin/csvq` and is executable. I ran it on `/data/staff.csv` and wrote both output files. I only spot-checked it on this one file, not on quoted fields with embedded commas, quotes or newlines.
+
+- **`/out/eng_top.csv`:** the eng rows, with columns `name,salary`, sorted by salary from highest to lowest. Cara and Finn both have 135000 and keep their input order, so Cara comes first.
+- **`/out/by_city.csv`:** columns `city,name`, sorted by city as text.
+- **Unknown column:** `csvq --select zz /data/staff.csv` printed `csvq: unknown column: zz` to stderr, nothing to stdout, and exited with code 2.
+
+Choices I made where your spec was silent:
+- **Numeric values:** any decimal or scientific-notation number counts as numeric, and surrounding spaces are ignored.
+- **Malformed `--where`:** a `--where` with no `=` also exits 2 with an error message.
+- **Unreadable file:** a file that can't be read exits 1 with an error message.
+- **Duplicate headers:** if a header name appears twice, the first matching column is used.
+
+To run it as plain `csvq`, `/home/eval/bin` has to be on your PATH. I only set that for my own session.

 Tool behavior: Python `csv` module for quoted commas/quotes/newlines, repeated `--where COL=VALUE` (split at first `=`, exact match), `--select` ordering, stable `--sort` (text / `--numeric` with non-numeric last in original order, `--desc` keeps non-numerics last), minimal quoting + `\n` endings, and `csvq: unknown column: NAME` on stderr with exit 2 and empty stdout on bad columns.

+
I wrote `/home/eval/report.sh` and ran it on `/data/inbox`. It exited with 0.
+
+**`/out/domains.txt`:**
+```
+4 x.org
+2 corp.io
+2 example.com
+1 sub.x.org
+```
+
+**stderr:** `skip: broken.json`. That file is cut off partway through, so it isn't valid JSON.
+
+I counted the addresses by hand from the message files and got the same totals. It found 9 recipients in 4 messages, and display names with commas in quotes (like `"Doe, John"`) were read correctly. `notes.txt` was ignored because it isn't a `.json` file, and `002 reply.json` and `004 fwd fwd.json` were read without trouble despite the spaces in their names.
+
+**How the script works:**
+- It's a bash wrapper around embedded Python. Python's built-in email-address parser splits the `to`/`cc` strings, so it handles quoted names with commas and `<…>` brackets.
+- It reads only regular files ending in `.json`, in file name order. Files that aren't valid JSON, or aren't a JSON object, are reported as `skip: <name>` on stderr, also in name order.
+- Domains are lowercased, so `Example.com` and `example.COM` count as one domain. Results are sorted by count (highest first), then by domain name.
+- Missing or empty `to`/`cc` fields are fine. An empty or missing inbox directory gives an empty output file, and the output's parent directory is created if needed. It always exits 0.
+
+One behaviour beyond what you asked for: if `to` or `cc` holds a list of strings instead of a single string, the script counts addresses from each string in the list.

I wrote `/home/eval/report.sh` and ran it on `/data/inbox`. It exited 0 and wrote `/out/domains.txt`:
+
+```
+4 x.org
+2 corp.io
+2 example.com
+1 sub.x.org
+```
+
+`broken.json` isn't valid JSON, so the script skipped it and printed `skip: broken.json` on stderr. `notes.txt` was ignored because it isn't a `*.json` file.
+
+The script runs Python from inside the bash file. It reads the `*.json` files in file-name order and parses the `to` and `cc` fields with Python's address parser. That parser handles quoted display names that contain commas, such as `"Doe, John"`. Domains are lowercased. The counts are sorted by count descending, then by domain.
+
+It also handles a few cases your examples didn't show. A missing or empty `to` or `cc` is skipped. If a field is a JSON list of strings, it joins them and counts them like a normal header. A JSON file whose top level isn't an object is ignored without a `skip:` message, since it is valid JSON.
+
+I only tested it on the five sample files in `/data/inbox`.

I've written both output files. The log has 12,000 lines: 11,987 are valid and 13 are malformed. All 13 bad lines are cut off after the method (e.g. `2026-10-01T00:13:00Z GET`).
+
+- **`/out/malformed.txt`** contains `13`.
+- **`/out/endpoints.tsv`** has the header plus one row for each of the 28 method/path groups. It's sorted as you asked and `error_pct` always has one decimal. The group counts add up to 11,987, so every valid line is counted once.
+
+The paths reduce to seven endpoints: `/`, `/health`, `/static/app.js`, `/api/items`, `/api/items/:id`, `/api/search` and `/api/users/:id/orders`. Each of the four methods (GET, POST, PUT, DELETE) hits all seven. The busiest groups:
+
+| method | path | count | p50 | p95 | error_pct |
+|---|---|---|---|---|---|
+| GET | /api/items/:id | 1711 | 470 | 863 | 4.0 |
+| GET | /health | 890 | 440 | 860 | 4.5 |
+| GET | / | 880 | 475 | 860 | 4.1 |
+| GET | /static/app.js | 878 | 447 | 871 | 5.4 |
+
+`error_pct` across all groups runs from 2.8 (`PUT /api/search`) to 7.6 (`PUT /api/items`).
+
+**How I applied the rules:**
+- **Valid line:** exactly five space-separated fields: a timestamp like `2026-10-01T00:00:00Z`, an uppercase method, a path starting with `/`, a 3-digit status and a latency like `35ms`.
+- **Path normalising:** I drop the query string first, then one trailing `/`, then turn all-digit segments into `:id`. So `/api/items/0/` and `/api/items/42` both become `/api/items/:id`.
+- **Percentiles:** nearest-rank, taking the value at position ceil(p/100 × count) in the sorted latencies.
+- **Rounding:** exact decimal arithmetic for half-up, so no floating-point rounding errors.
+
+The script is at `/tmp/p.py` if you want to run it again.

I wrote both files to `/out`. 13 of the 12,000 lines in `/data/app.log` are malformed, and the other 11,987 fall into 28 method and path groups.
+
+- **Malformed lines:** all 13 stop after the method, for example `2026-10-01T00:13:00Z GET` with no path, status or latency. `/out/malformed.txt` contains just `13`.
+- **Endpoints:** `/out/endpoints.tsv` has the header and 28 group rows, sorted by count descending, then method, then path. The busiest group is `GET /api/items/:id` with 1,711 requests, p50 470 ms, p95 863 ms and 4.0% errors.
+
+I checked only the top few rows of the TSV by eye, not the whole file.

I've written cleaned copies of the six `.txt` files to `/out/clean/` and created `/out/manifest.tsv`. I checked the bytes of every output file: they're all UTF-8 with no BOM, contain only `\n` line endings, and end with exactly one newline.
+
+`/out/manifest.tsv`:
+```
+name	encoding	lines	chars
+a.txt	utf-8	2	24
+b.txt	utf-8-sig	2	26
+c.txt	latin-1	2	23
+d.txt	utf-16	3	16
+e.txt	utf-8	2	30
+f.txt	latin-1	3	17
+```
+
+What was done to each file:
+- **a.txt:** already clean UTF-8, copied unchanged.
+- **b.txt:** removed the UTF-8 BOM and converted `\r\n` to `\n`.
+- **c.txt:** isn't valid UTF-8, so it was read as latin-1 ("Señor Müller", "À bientôt"). Added a final `\n`.
+- **d.txt:** UTF-16 with a byte-order mark ("Ωmega", "κόσμε", "end"). Converted `\r\n` to `\n`.
+- **e.txt:** plain ASCII, so it counts as utf-8. Added a final `\n`.
+- **f.txt:** used old Mac-style lone `\r` line endings, which became `\n`. It was read as latin-1 because of a `£` byte.
+
+`g.TXT` was skipped because only lowercase `.txt` names count, so it isn't in `/out/clean/` or the manifest.

+I only spot-checked `a.txt`, whose raw bytes are valid UTF-8 and were detected as `utf-8`. I did not open the output files to check their contents.

I wrote `/home/eval/ingest.py`, ran it on day1 and then day2 into `/var/lib/ledger.db` (creating the database), and wrote `/out/balances.csv`.
+
+| File | new | dup | bad | Rows rejected for bad amounts |
+|---|---|---|---|---|
+| day1.csv | 4 | 1 (the second `t2`) | 1 | `t4` (`1.999` has three decimals) |
+| day2.csv | 2 | 1 (`t3` from day1) | 2 | `t7` (`abc`), `t9` (`.5` has no digit before the point) |
+
+When a row is a dup, its new values are ignored. The second `t2` (-99.00) and the day2 `t3` (300) did not change anything.
+
+`/out/balances.csv`:
+```
+account,balance
+acme,87.45
+bolt,3.00
+cato,0.10
+dyn,-7.25
+```
+
+**Repeat runs:** I ran day1 a second time to test this. Nothing new was stored and the stored data stayed the same; the output was `new=0 dup=5 bad=1`. `t4` is reported as bad again because rows with bad amounts are never stored, so they don't count as dups later.
+
+**How the script works:**
+- Each file is handled in one all-or-nothing transaction, so a crash partway through leaves the database as it was.
+- Amounts are checked against the format you gave and converted straight to whole cents, so there are no rounding errors.
+- At the end of each run, `balances` is rebuilt from `txns`, so it always matches the per-account totals.
+
+The CSV export isn't part of `ingest.py`; I wrote it with a separate one-off snippet. If you want the export to happen automatically after each batch, I can add it to the script.

I wrote `/home/eval/ingest.py`, ran it on both batches, and wrote `/out/balances.csv`.
+
+**Results:**
+
+| Run | Output |
+|---|---|
+| day1 | `new=4 dup=1 bad=1` |
+| day2 | `new=2 dup=1 bad=2` |
+
+- **Bad amounts:** `t4` (`1.999`), `t7` (`abc`) and `t9` (`.5`) were skipped, each with a `bad amount: <txn_id>` line on stderr.
+- **Duplicates:** `t2` in day1 and `t3` in day2 were ignored as dups, even though their fields differed from the stored rows.
+- **Re-run check:** I ran day2 a second time as a test, and it gave `new=0 dup=3 bad=2`. This means the first-time run on day2 is no longer the last thing in the DB log, but the data was unchanged. Bad rows are never stored, so they are counted as bad again on every re-run.
+- **Consistency check:** the stored balances match the per-account sums of `txns`.
+
+**`/out/balances.csv`:**
+```
+account,balance
+acme,87.45
+bolt,3.00
+cato,0.10
+dyn,-7.25
+```
+
+Each run is a single transaction, so a crash partway through leaves the DB unchanged.

I rendered both environment configs and the index. I checked the output against the merge rules by reading it, and it matches.
+
+**Files written:**
+- `/out/dev.json`
+- `/out/prod.json`
+- `/out/index.txt`, which lists `dev` and `prod`, one per line.
+
+`/config/env/` also contains a `README.md`. Only `*.toml` files are processed, so it was left out.
+
+**What the merge did:**
+- **dev:**
+  - `port` and `tags` replaced the base values; the tags list became `["dev"]` rather than being combined with the base list.
+  - `server.tls.cert` was removed by `"__unset__"`.
+  - `db.pool.max` was overridden to 2 and `min` = 1 was kept from base.
+  - New keys `debug` and `greeting` were added; the Ukrainian text in `greeting` is written as-is, not as `\u` escapes.
+- **prod:**
+  - `maintenance` was removed.
+  - `workers` and `tls.enabled` were overridden, the database `url` was changed and a `db.replica` table was added.
+  - The `routes` list was replaced entirely by prod's single `/` → `cdn` route, so the base `/api` route is not in prod's output.
+- **Dates:** these became isoformat strings, for example `"2026-09-30"` and `"2026-10-12T02:00:00+02:00"`.
+
+The JSON uses 2-space indentation and sorted keys, and every file ends with a newline. The script is at `/tmp/render.py` if you want to run it again.

I rendered both environments and wrote the files to `/out`:
+
+- `/out/dev.json`
+- `/out/prod.json`
+- `/out/index.txt` (contains `dev` and `prod`, one per line)
+
+I checked the output by reading the three files back. The merge rules and JSON formatting you gave are implemented as written. The script is `/tmp/r.py`, so you can re-run it if the configs change.
+
+- **dev:** `debug` is `true`, `server.port` is 3000 and `server.tags` is `["dev"]`. `server.tls.cert` and `db.pool.maintenance` were removed by `__unset__`. The Ukrainian `greeting` is written as-is, not as `\u` escapes.
+- **prod:** `routes` is replaced by the single CDN route rather than merged with the base routes. It adds `db.replica`, sets `server.workers` to 16 and enables TLS while keeping the base cert path.
+- **Dates:** `released` comes out as `"2026-09-30"` and `maintenance` as `"2026-10-12T02:00:00+02:00"`.
+
+`/config/env/README.md` is not a `.toml` file, so it was skipped. `maintenance` is a top-level key in `base.toml`, so the `__unset__` on `db.pool.maintenance` in `dev.toml` removed nothing. That key doesn't exist under `db.pool`, and the base `maintenance` date is still in both outputs. If you meant to remove the top-level key, the line in `dev.toml` needs to sit outside the `[db.pool]` table.

Bash also turns off `set -e` inside a function whose result is being checked or piped, so failures inside each stage were ignored too.\n2. **Extract failures were hidden.** `local rows=$(...)` always succeeds, which masked a failing extract. That stage also kept the CSV header row and put the columns the wrong way round (amount, region instead of region, amount), so the totals were wrong.\n3. **Publish overwrote the old summary even on failure.** It wrote straight into `dist/summary.txt` through a pipe, so the file was emptied before anything had been checked.\n\n**What I changed:**\n- **Extract:** it skips comment lines and the header and outputs `region,amount`.\n- **Every stage:** each one checks its own commands and returns an error if any fail. The main part of the script runs the four stages in order and stops at the first failure, saying which stage failed.\n- **Validate:** it now also fails if there are no totals at all.\n- **Publish:** it writes to a temporary file in `dist/` and only moves it over `dist/summary.txt` if everything succeeded. If any stage fails, the old file is left exactly as it was.\n- **Exit code:** the output still goes through `tee` into `build/build.log`, and because the script uses `pipefail`, a failure still makes it exit non-zero.

Each stage now runs plainly under `set -e`, so a failure stops the build with a non-zero exit.\n- **Wrong columns:** `extract` took fields 2,3 (amount, region) instead of region, amount. It also let the `id,amount,region` header row through. It now writes `region,amount` and skips the header.\n- **`dist/summary.txt` clobbered on failure:** `publish` wrote straight into the file, so a failure left it truncated. It now writes to a temp file in `dist/` and moves it into place only on success.\n- **Stale totals:** `build/totals.csv` and `build/extracted.csv` are now deleted at the start of each run, so a failed stage can't leave old totals for a later stage to use. `validate` also fails if the totals file is empty.\n\nI didn't touch `tests/` or `data/`, and the script doesn't read `tests/expected-summary.txt`.\n\nThe `build/` directory and `dist/summary.txt` show up as untracked files.

The second TX-0007 had the same date and amount as the first (`15` vs `15.00`). The last TX-0004 row also repeated an earlier one (`89.990` vs `89.99`).\n- **Mismatches:** TX-0010 has both a different amount and a different date, so it appears in both sections. The other three amount differences (TX-0003, TX-0010, TX-0011) look like transposed or mistyped digits.\n- **Missing:** TX-0009 (Soylent, 77.70) is in our books but not at the bank. TX-0101 (42.00, \"UNKNOWN DEPOSIT\") is at the bank but not in our books.\n\n**How it works:** the script is plain awk, with no Python. It reads the quoted CSV fields itself, so commas and doubled quotes inside quotes are handled. It converts every amount to a whole number of cents, so nothing is compared as a floating-point value. Bank refs are trimmed and uppercased, and DD/MM/YYYY dates are turned into YYYY-MM-DD before matching.

Any other new CSV would have been missed the same way.\n- The rules didn't list `lib/sum.awk`, `lib/fmt.awk` or `data/regions.map` as inputs. Changing them, like the recent region renames and the CSV-header change, didn't count as a reason to rebuild.\n\n**The changes:**\n```make\nCSVS := $(wildcard data/*.csv)\nSUMS := $(patsubst data/%.csv,build/%.sum,$(CSVS))\n\nbuild/%.sum: data/%.csv lib/sum.awk Makefile\nbuild/report.txt: lib/fmt.awk data/regions.map $(SUMS) Makefile\n```\n- The report recipe now passes `$(SUMS)` to awk instead of `$^`. Otherwise the new inputs would be handed to awk as if they were data.\n- It also creates `build/` if it doesn't exist.\n- Both rules depend on the Makefile itself, so editing a recipe also triggers a rebuild.\n\n**Checks:**\n- `make test`: touching each input (both awk scripts, `regions.map`, and each CSV) marks the report out of date, and a new `data/latam.csv` gets built and appears in the report.\n- Plain `make` rebuilt all three summaries, including the new `apac.sum`, then the report. `make -q` now says everything is up to date.\n\nOnly the Makefile is in the commit. Git doesn't show build/report.txt as changed, so the copy already committed has the same contents as the rebuilt one.

If the folder `DEST` goes in doesn't exist, it now exits with 4 before doing anything, instead of failing with some other error.\n- **Validation:** Before, any line that merely started with a lowercase letter or underscore was accepted, so `max conns=5` got through. Now the key must match `^[a-z_]+=`, and a bad line prints `publish: bad line N` and exits with 3.\n- **Last line without a newline:** It used to be silently dropped. It's now read; `feature_flags=a=1,b=0` in `prod.conf` is exactly that case.\n- **Temporary files:** One temp folder was never deleted, and the cleanup step was replaced by a later one. Now one cleanup step removes everything on every exit, including errors and interrupts.\n- **Output on success:** The stray `publish: done` is gone, so a successful run prints nothing.\n- **Leaving `DEST` untouched on failure:** The output is written to a temporary file in the same folder as `DEST` and then renamed into place in one step. A failed run never touches `DEST`, and the published file gets normal permissions.\n- **Sorting:** Lines are sorted by key in byte order (`LC_ALL=C`), so `a` comes before `a_b`.\n\n**The published file, `site/config.txt`:**\n```\ndb_url: postgres://db/shop?sslmode=require\nfeature_flags: a=1,b=0\nname: shop\nregion: eu-west\ntimeout_s: 30\n```\n\n`site/config.txt` and the test outputs under `build/` aren't committed and still show as untracked.

The old pattern only checked the first character.\n- **Last line and empty files:** a last line with no trailing newline is now read, and an empty source gives an empty destination.\n- **Untouched destination:** the output is built in the temp directory and copied to the destination only after the whole source validates, so a failure leaves it as it was.\n\nI added one exit I wasn't asked for: an unreadable or missing source file exits 1 with a message.\n\nI committed only `bin/publish`. `site/config.txt` and the files `make test` generates under `build/` are untracked and not in the commit.", + "iterations": 5, + "metadata": { + "bashkit": { + "dirs": [], + "last_exit_code": 0, + "links": {}, + "tool_outputs": [ + { + "commands": "cd /home/eval/publisher; git log --oneline | head; git status --short; ls -R . | grep -v '^./.git' | head -50; cat bin/publish; cat Makefile; cat etc/prod.conf", + "exit_code": 0, + "stderr": "", + "stdout": "commit b464d971\nAuthor: Eval Agent \nDate: Fri Oct 09 22:15:58 2026 +0000\n\n initial import\n\nOn branch master\n\nnothing to commit, working tree clean\n.:\nMakefile\nbin\netc\nsite\ntests\n\n./bin:\npublish\n\n./etc:\nprod.conf\n\n./site:\nREADME\n\n./tests:\nfixtures\ntest_publish.sh\n\n./tests/fixtures:\nbad.conf\nempty.conf\ngood.conf\ngood.expected\n#!/bin/bash\n# publish SRC DEST: render the key=value file SRC into DEST as \"key: value\"\n# lines sorted by key (LC_ALL=C byte order).

The loop itself is a → b → c → a; d and g are listed because they depend on it.\n- **`build/cycle.rc`**: `1`.\n\n**How the script works**\n- It's a bash wrapper around one awk program. It reads the file once: it strips comments, ignores blank lines, allows spaces or tabs around names and the colon, adds up deps across repeated lines, and ignores duplicate deps.\n- Each step it emits the smallest package (byte order) whose deps have all been emitted. If packages are left that can't be emitted, it prints `cycle: …` to stderr with them sorted, and exits 1.\n- After the first run I fixed one bug: awk compares names that look like numbers as numbers (so `9` would sort before `10`). The script now always compares names as text, which gives true byte order (`10` before `9`).

It finished without errors, and `app.db` is now at version 2.\n\n**What the migration does** (all in one transaction, so a failure leaves the database unchanged):\n1. **Merges duplicate users:** emails are compared after trimming and lowercasing. Each order is moved to the lowest user id that shares its user's email.\n2. **Builds the new users table:** it has exactly the five columns you specified, in that order, and keeps the user ids. Only the lowest id from each email group is copied over.\n - **Names:** `full_name` is trimmed, then split at the first space. With no space, `last_name` is `''`.\n - **Email:** trimmed and lowercased.\n - **Date:** `MM/DD/YYYY` becomes `YYYY-MM-DD`. Dates without leading zeros, like `1/5/2020`, are padded.\n3. **Swaps the tables:** it drops the old `users` table and renames the new one to `users`.\n4. **Updates the version:** sets `meta.schema_version` to `'2'`, and adds that row if it's missing.\n\n**Result in `app.db`:**\n- User 4 (`ADA@example.com`) was merged into user 1, so orders 101 and 104 now belong to user 1.\n- User 2 became `Grace` / `Brewster Hopper` / `grace@navy.mil` / `2024-01-05`.\n- User 3 became `Linus` with last name `''`.\n- All 5 orders are still there with their original totals.\n\n**Testing:**\n- **Second, different database:** I built a fresh v1 database with extra rows: a messy name with extra spaces, an uppercase email with spaces around it, a duplicate where the higher id comes first, an un-padded date, and an order pointing to a user that doesn't exist. Everything converted as expected, and the order with the missing user kept its original `user_id`.\n- **Final file vs. live database:** I tweaked the date handling after migrating `app.db`. Running the final file on a backup of the original produced exactly the same result as the live database.\n\n**Limits:**\n- Lowercasing only changes the letters A–Z, so two emails that differ only in accented or other non-English letters won't be merged.\n- Running the file a second time on an already-migrated database will fail, because the `full_name` column no longer exists.", + "iterations": 5, + "metadata": { + "bashkit": { + "dirs": [], + "last_exit_code": 0, + "links": {}, + "tool_outputs": [ + { + "commands": "cd /app;

That file is cut off partway through, so it isn't valid JSON.\n\nI counted the addresses by hand from the message files and got the same totals. It found 9 recipients in 4 messages, and display names with commas in quotes (like `\"Doe, John\"`) were read correctly. `notes.txt` was ignored because it isn't a `.json` file, and `002 reply.json` and `004 fwd fwd.json` were read without trouble despite the spaces in their names.\n\n**How the script works:**\n- It's a bash wrapper around embedded Python. Python's built-in email-address parser splits the `to`/`cc` strings, so it handles quoted names with commas and `<…>` brackets.\n- It reads only regular files ending in `.json`, in file name order. Files that aren't valid JSON, or aren't a JSON object, are reported as `skip: ` on stderr, also in name order.\n- Domains are lowercased, so `Example.com` and `example.COM` count as one domain. Results are sorted by count (highest first), then by domain name.\n- Missing or empty `to`/`cc` fields are fine. An empty or missing inbox directory gives an empty output file, and the output's parent directory is created if needed. It always exits 0.\n\nOne behaviour beyond what you asked for: if `to` or `cc` holds a list of strings instead of a single string, the script counts addresses from each string in the list.", + "iterations": 3, + "metadata": { + "bashkit": { + "dirs": [], + "last_exit_code": 0, + "links": {}, + "tool_outputs": [ + { + "commands": "cd /data/inbox;

So `/api/items/0/` and `/api/items/42` both become `/api/items/:id`.\n- **Percentiles:** nearest-rank, taking the value at position ceil(p/100 × count) in the sorted latencies.\n- **Rounding:** exact decimal arithmetic for half-up, so no floating-point rounding errors.\n\nThe script is at `/tmp/p.py` if you want to run it again.", + "iterations": 5, + "metadata": { + "bashkit": { + "dirs": [], + "last_exit_code": 0, + "links": {}, + "tool_outputs": [ + { + "commands": "ls -la /data/;

generate 13-15/15); GPT-6 models pending (OpenAI credit). The homepage eval table now only lists runs over the newest run's task count, so scores on different dataset sizes never mix. Results in `crates/bashkit-eval/README.md`. * **Test**: `bashkit_generate` eval (`just eval-generate`): one-shot script generation, 15 tasks (`basic`/`hard`). The model gets the task and a fixed sandbox description, answers with one bash script (no tools, no feedback), bashkit runs it once on `build_task_bash` and the shared expectations scorer scores it. Extraction: first `bash`/`sh`/`shell` fence, else first untagged fence, else the whole reply; no script scores 0, provider errors are N/A. Providers omit `tools` when none are offered. References pass in `cargo test -p bashkit-eval` and under real bash 5.2; `true` fails every task. See operations/eval "Generate Eval". * **Test**: `mode=runtime` eval tasks (`just eval-runtime`, tag `runtime` in `bashkit_bash`): 12 tasks where bashkit is the agent's execution runtime: python3 file-processing scripts (CSV, JSONL, logs, encodings, TOML), python3 + bash pipelines, sqlite3 (CSV load and reports, a reusable migration file), and state across calls (a CLI on PATH, an idempotent SQLite ingester). Every eval `Bash` now has real CPython (`cpython` feature) and sqlite (`sqlite` feature, opt-in env set), and the model's tool prompt lists them. Tasks gain a hidden `verify` script, run after the agent in a fresh `Bash` on the same filesystem, whose output is scored (`/.eval/verify.out`): it re-runs what the model built on unseen input. References pass in bashkit and against real python 3.13 / sqlite3 3.45 / bash 5.2. See operations/eval "Runtime Tasks". * **Fix**: gaps found by the runtime tasks. A script run by path or `PATH` whose shebang names a registered non-shell builtin (`#!/usr/bin/env python3`, `#!/usr/bin/awk -f`) now runs that builtin on the script path, as the kernel would; it was stripped and the Python ran as bash. The sqlite builtin persists databases in rollback-journal mode (header bytes 18/19 = 1): Turso writes WAL headers, which CPython's WASI SQLite (built without WAL) rejected as "file is not a database", so `python3` could not open a db made by `sqlite3`. Open: `printf '\x00'` drops NUL bytes; sqlite `csv` quoting and error exit codes differ from the sqlite3 shell (runtimes/sqlite-builtin "Output formatting"). diff --git a/site/src/content/home.ts b/site/src/content/home.ts index 8e30e7c22..aef7e4992 100644 --- a/site/src/content/home.ts +++ b/site/src/content/home.ts @@ -15,7 +15,9 @@ export const builtinCount = inventory.builtins.length; // timeline (site/scripts/build-performance-data.mjs, fed by // crates/bashkit-eval/results), not hand-copied, so it can't lag the README. // It shows every model's latest full run from the newest eval lineup (runs -// within LINEUP_WINDOW_DAYS of the newest one), best score first. +// within LINEUP_WINDOW_DAYS of the newest one), best score first.

Excluding it keeps coverage on main's feature set; eval tests still run in CI's test job.
