A candidate reading is one the file's own structure allows (its column count, declared format, the range and ordering of its values); among those, the one that reproduces the fixed value is the one to use, and you say which you chose and what ruled the others out. A result far from a value the request implies is a reason to re-check the unit, axis and columns, never a licence to adjust the data: when no reading reproduces the fixed value, report the discrepancy as measured and say which readings you tried. | ||
| - Think in the workspace, not in your head. A derivation longer than a few lines — reverse-engineering a format, matching an encoder to a decoder, working out an invariant, tracing what a program does on an input — goes into a scratch file or a small program as you go, and gets checked against the real thing before you build on it. Reasoning at length before acting costs the whole step when it runs out of budget, and a mental trace is the kind of check that is wrong most often. | ||

Do not infer path role from file extensions
A path's spelling does not reliably identify whether it is a file or directory: /tmp/output can be an extensionless file, while /tmp/results.json can be a directory. For contradictory descriptions, this instruction can cause the agent to create or write the wrong target, and “implement so that every reading is satisfied” cannot resolve mutually exclusive filesystem roles. Use the request's explicit role when it is unambiguous and ask for clarification when the ambiguity changes the target, rather than applying the extension heuristic.

Reject URL separators before scanning absolute paths
A request containing https://example.com/report.json starts scanning at the first slash because the preceding : is not a path character. The resulting token is //example.com/report.json, which passes the segment and extension checks, is reported missing, and causes a valid final answer to be held while the model is instructed to write that bogus path. Treat a slash preceded by : as part of a URL rather than the start of an absolute filesystem path.

Do not infer path type from filename extensions
This parenthetical is false for valid concrete inputs: a file can be named README without an extension, and a directory can be named src.v1 with a dot. Because the instruction presents this as the way to satisfy both readings, an agent can choose the wrong interpretation and then report a check as proof, or create the wrong filesystem object. Remove the heuristic and require the surrounding requirements and final environment to establish whether the path is a file or directory.

Remove completed runs from the state map
runs is keyed by the process-unique instance ID, but entries are removed only from on_error. Every normally completed run therefore leaves its candidates and flags in this HashMap permanently; a long-lived harness handling many turns will grow without bound. Add normal-run cleanup (for example, an appropriate completion hook) so the entry is removed after the run finishes, not only when it errors.

Do not log user-controlled requested paths
missing contains paths extracted directly from the user's request and may include sensitive filenames or directory names. Logging the entire vector at info level violates the repository rule against logging full user content or sensitive data and exposes those names to application logs. Log only a count or a fixed diagnostic, as the final-answer path already does.

Restrict deliverable checks to the workspace
candidate_paths accepts arbitrary absolute paths, and this code passes them directly to Path::exists(). A caller who controls the request can therefore make the agent probe whether files outside its workspace exist; the result influences the injected continuation and can be used as a filesystem-existence side channel. Resolve candidates against an explicitly allowed workspace root and reject anything outside it before checking.

Cover the after_tool clock-band notes with a test
The half-time and late notes are new behaviour (two RunState flags, TurnClock::band(), note text and one-shot firing) and the module doc comments state they fire exactly once per run, but no test in unmet_deliverable_tests.rs drives after_tool through a clock band. A regression that never appends the notes, or appends them on every tool result, would pass the current suite. Add a test that constructs a TurnClock in the ≥5 and ≥8 bands (however testkit exposes it) and asserts the note appears once and only once.

No end-to-end test drives the unmet-deliverable hold on a live chat turn
This new middleware changes observable chat behaviour: a turn whose first user message names an absolute path with an extension that nothing created will have its final answer held and a harness instruction injected. No e2e test covers this — the candidates are pre-existing specs mentioning 'orchestrator' for other reasons, and no workflow gained a case for it. A test would have to: boot the app (or core in-process via the Rust E2E mock-backend lane), script the mock LLM so the orchestrator names an unwritten output path and then answers without writing it, and assert the answer is withheld and the injected notice reaches the next model request (or surfaces in the transcript).

- Around line 155-162: Update the notice in `wrap_harness_instruction` and the
matching `half_time_note` so they direct the agent to write an absent file only
when the request asks for it as output; when the path is merely a reference or
remote input, tell the agent not to create it and to answer normally.
- Around line 101-107: Update candidate extraction in candidate_paths to skip
slash sequences following a colon and tokens beginning with double slashes, so
URL paths are not treated as local file candidates. Add a URL case to
only_absolute_paths_carrying_a_file_extension_are_candidates and preserve
extraction of valid absolute file paths.
- Around line 307-315: Update the candidate-path extraction in the harness to
use only the current turn’s user request, not the first user message in the full
history. Use turn-specific text from the run context or capture the current-turn
message before follow-ups and injected messages are added, then pass that text
to candidate_paths.
- Around line 256-265: Update `missing` to translate `/workspace` candidate
paths to the host `action_dir` before checking existence, while retaining the
original paths in its results. If the middleware cannot access a stable
`action_dir` mapping for a Docker-sandboxed turn, skip the missing-deliverable
check for that turn.

Map sandbox paths before checking deliverables.
A Docker-sandboxed tool runs outside the core process. The sandbox mounts the host action_dir at /workspace, but missing checks the raw path in the host filesystem. If a request names /workspace/output/report.json, the tool can create it in action_dir/output/report.json while missing checks host /workspace/output/report.json. The middleware can then report a false missing file and hold the answer.
Map /workspace paths to the host action_dir before checking them. If no stable mapping is available, skip this middleware for Docker-sandboxed turns.

Not mapped in this PR. The middleware checks the filesystem the core runs on, which is the one the shell tool writes to in every configuration this was measured in (the benchmark container, the CLI, library hosts without a sandbox). Under the Docker sandbox the guest /workspace is the host action_dir, and the harness assembly does not carry that mapping today, so a request naming /workspace/... on a sandboxed turn would be held once with the new notice, which now allows the model to say the file exists elsewhere and answer. A with_path_mapping(guest_root, host_dir) on the middleware, fed from the sandbox config, is the right follow-up once the assembly has it.

@sanil-23 Thanks for the clarification. The host-filesystem check fits the configurations you measured. The revised notice limits the impact of a false missing-file result under Docker, but the path mismatch remains.
I accept deferring the mapping to a follow-up. Would you like me to open an issue for with_path_mapping(guest_root, host_dir) and its sandbox-config wiring?

Learning: In OpenHuman, the Docker sandbox mounts the host `action_dir` at guest `/workspace`. Host-side existence checks in `crates/openhuman-core/src/agent/tinyagents/middleware/unmet_deliverable.rs` must distinguish guest paths from host paths. The maintainer recommends a follow-up `with_path_mapping(guest_root, host_dir)` API on the middleware, supplied from sandbox configuration.

Reject non-filesystem prefixes before scanning paths
A URL such as https://example.com/output.json still reaches this scanner: the first slash is accepted because the preceding : is not a path character, and the resulting //example.com/output.json can be treated as an absolute filesystem candidate. Exclude URL schemes and other non-filesystem prefixes before accepting / as a path start.

This file adds no focused tests for those exact transitions, so regressions in inclusive band handling or repeated tool results can ship unnoticed.
Additional security observation
Cover the after_tool clock-band notes with a test
[RULE] clock-band-test-coverage
The new after_tool behavior has separate half-time and late-time branches, one-shot state transitions, and a precedence rule where the late note suppresses the half-time note. The added test module declaration does not provide visible coverage for these clock-band cases. Add deterministic tests covering both thresholds, repeated calls, missing versus already-created paths, and the late-band precedence.

Add an end-to-end test for the unmet-deliverable hold
There is no end-to-end test driving a live chat turn where the model names an output file, omits writing it, and this middleware sets continue_turn with the remediation notice. Unit tests of the parser would not catch middleware ordering, filesystem timing, or whether the held response actually produces the follow-up turn.

No end-to-end test drives the unmet-deliverable hold on a live chat turn
[RULE] missing-e2e-coverage
Still standing: the harness-level tests here cover the middleware in isolation, but no test runs the hold through a real chat turn in the host (session host → harness → notice surfaced to the model and the user). The prior review raised this; the isolated tests are good but the integration path — including interaction with verify_before_finish installed by harness_assembly on the same turn — remains unexercised.

Require a regular file before treating a deliverable as written
Path::exists() is also true for directories. If the request names /tmp/report.json and a directory with that name exists, the middleware considers the deliverable satisfied and allows the final answer through even though no output file was written. Check that the path is a file (for example with is_file()), according to the intended symlink policy.
Additional tests observation
Restrict deliverable checks to the workspace
[RULE] unconfined-filesystem-probe
Still unfixed: missing() stats any absolute path extracted from the request, with no confinement to the turn's workspace. A request that names /etc/... or another user's path causes filesystem probes outside the sandbox the turn operates in. Resolve candidates against the workspace root (or reject paths outside it) before calling exists().
Additional e2e observation
Restrict deliverable checks to the workspace
[RULE] unrestricted-fs-probe
missing() stats every absolute path extracted from the user's request, wherever it points — /etc/..., /proc/..., another user's home. The existence result is then reflected back into the model conversation, so the turn's behaviour becomes a function of arbitrary host filesystem state outside the workspace. Constrain candidates to paths under the turn's workspace root before statting.

Do not infer path role from file extensions
A filename extension does not reliably identify whether a path is a file: directories may contain dots, and files may have no extension. This instruction can make the agent create, inspect, or modify the wrong path when the request is ambiguous.

Reject URL separators before scanning absolute paths
A URL such as https://host/output.json can be scanned from its second slash and become a candidate resembling //host/output.json. The middleware then performs a filesystem existence check on that user-controlled token and may emit a misleading harness instruction. Exclude URL schemes and network-path references before treating slash-delimited text as a local absolute path.

Do not infer path role from file extensions
This test suite continues to encode the extension heuristic as the contract for deciding which request tokens are deliverables. File extensions do not distinguish an input from an output, so a request naming an existing input with an extension can still be treated as an unmet deliverable. Use explicit output semantics or workspace-aware operation metadata instead of inferring role from the filename.
Additional critique observation
Test URL-like references and extensionless deliverables
[RULE] missing-coverage
These tests encode the extension-based heuristic but do not cover the concrete false-positive case https://host/path/result.json: the parser can treat the slash after : as an absolute path candidate. They also do not cover a legitimate extensionless output such as /app/output/report, so a regression in the path-role heuristic would pass this suite. Add assertions for URL-like references and for the intended behavior of extensionless deliverables, or adjust the production parser and test its contract explicitly.

Do not infer path role from file extensions
Enabling this middleware activates candidate detection that treats an absolute path with a file extension as a deliverable.

Do not infer deliverables from file extensions
A valid extensionless deliverable such as /workspace/output is discarded before the existence check, so the middleware cannot hold a final answer for it. File extensions do not distinguish deliverables from references; candidate detection needs to support extensionless paths or use a stronger request/path contract.

Require a regular file before accepting a deliverable
This test locks the middleware to existence-only semantics, so a directory at report.json would satisfy the deliverable check even though no file was written. A request can create or encounter a directory at the requested path; that must remain unmet until the path refers to a regular file. Change the assertion and implementation contract to use a regular-file check rather than exists() alone.

Do not classify user messages by marker substring
A legitimate user request containing the literal <harness_instruction> marker is excluded from consideration, even though it is a Message::User. For example, a request that quotes that tag while asking for /workspace/output.pdf causes this search to skip the current request and potentially select an older user message or no message at all, so the unmet-deliverable hold never fires. Distinguish actual harness-injected messages using their structured metadata or an exact wrapper representation rather than searching untrusted message text for a substring.

Do not infer deliverable paths from filename extensions
This test requires a filename extension before a path can be considered a deliverable. That rejects a valid request such as write the result to /app/output/report and can also classify an input file with an extension as an output candidate. Path role cannot be reliably inferred from extension; the extraction and hold logic needs an explicit output signal or a less lossy request interpretation.

Remove completed runs from the state map
Successful runs are marked fired but never removed from runs; only the error path removes them. Because the middleware is installed on long-lived harnesses and keys state by every instance id, this retains candidate path strings and bookkeeping for every completed turn indefinitely. Remove the entry once the run reaches its terminal successful path, while preserving the state needed for any subsequent continuation.

State is inserted in before_model and removed only by on_error; successful runs, including runs that fire the continuation and later complete, remain in runs forever.

Do not infer deliverables from file extensions
A user request is untrusted input, and requiring a filename extension still causes extensionless deliverables to be ignored while treating arbitrary prose such as /tmp/report.data as a deliverable candidate. Identify deliverables from an explicit structured contract or validate candidates against the actual requested output semantics rather than the suffix.

Restrict deliverable existence checks to the workspace
The request controls each absolute path passed to Path::exists, so a caller can make the process probe arbitrary filesystem locations outside the workspace. Even though only existence is checked, this creates a filesystem existence oracle and can cause the middleware to include host paths in model instructions. Resolve candidates under the active workspace and reject paths that escape it before checking them.

The clock-driven behavior has distinct half-time, late, exact-boundary, and skipped-band paths, but this file only declares an external test module and provides no coverage for those transitions. Tests should verify half-time and late notes at their boundaries and the behavior when the first callback is already late, otherwise regressions in the one-shot flags can silently suppress required guidance.

Cover the after-tool clock-band transitions
The clock-driven behavior has boundary-sensitive half-time and late transitions, including skipped bands and exact threshold behavior, but this change provides no visible tests for those paths. Add deterministic unit coverage for the half-time threshold, late threshold, and a tool result that jumps directly from an earlier band to the late band.

Cover the after_tool clock-band notes with a test
The half-time and late notes are behavioural logic (band thresholds, once-per-run flags, note contents) with no test: every test in unmet_deliverable_tests.rs exercises the after_model hold, and none drives after_tool. A regression that fires the half-time note every round, or never, would not be caught. Raised in earlier revisions; the new tests do not cover it.

Restrict deliverable existence checks to the workspace
missing stats any absolute path the extraction produces, wherever it points. The traversal guard only rejects ..; a request naming /etc/shadow.conf or /proc/self/environ.txt gets a stat outside the turn's workspace, and the answer to the model's context reveals whether the path exists. Restricting the check to paths under the turn's working directory (as the requirements check does) would close the oracle. Raised in earlier revisions; unchanged.

No end-to-end test drives the unmet-deliverable hold on a live turn
The install call puts the middleware on every live root orchestrator turn served through the app, but no spec in app/test/e2e/specs/ exercises it: none of the chat-harness specs send a request that names an absolute output path, so the continue_turn hold, the half-time and late clock-band notes, and the interaction of this rung with the existing requirements check are never driven through the running system the way a user would. The candidates above that mention "orchestrator" are the pre-existing subagent-delegation specs and do not touch this behaviour. A test would need to send a chat turn whose request says to write a result to a named file path (which the mock backend can arrange never exists), let the mock model answer without calling the writer, and assert the turn continues once and the notice reaches the model. Until then a wiring mistake — wrong scope, wrong budget, ordering against verify_before_finish — regresses silently in production while all in-repo tests pass. Repeated from earlier revisions; unchanged.
Additional tests observation
Test the unmet-deliverable hold on a live chat turn
[RULE] missing-test-coverage
The tests call install on a bare AgentHarness they build themselves; nothing exercises the assembled production harness (harness_assembly) to confirm the middleware is actually pushed onto a real orchestrator turn, in the right order relative to the other rungs. If the install call is later dropped or reordered behind a rung that consumes the answer, no test fails. Raised in earlier revisions; still no wiring-level test.

Add the referenced unmet-deliverable module
Rust module resolution cannot find crates/openhuman-core/src/agent/tinyagents/unmet_deliverable.rs (or an inline module), so this declaration causes compilation to fail. Add the missing module in the same change, or remove this declaration and the associated re-export until its implementation is present.
Additional security observation
Do not infer deliverables from filename extensions
[RULE] avoid-extension-inference
The activated candidate parser only accepts absolute paths whose final component has a one-to-eight-character extension. Valid extensionless deliverables, dotfiles, and longer extensions are ignored, so the middleware can let a turn finish without producing the requested file. Identify candidates from path semantics and workspace resolution rather than requiring an extension.
Additional security observation
Do not log user-controlled requested paths
[RULE] avoid-sensitive-logging
The newly activated middleware logs the full missing path list at info level. Those paths come directly from the user's request and may contain sensitive filenames or directory structure; repository rules prohibit logging full user-controlled content. Log only a count or a fixed classification, not the paths themselves.
Additional security observation
Require a regular file before accepting a deliverable
[RULE] require-regular-file
The activated deliverable check treats any existing path as written, including directories, because it uses existence alone. A directory named with a file extension can therefore suppress the hold and make the turn appear to have produced its output. Require is_file() after applying the workspace restriction.
Additional security observation
Remove completed runs from the state map
[RULE] bound-run-state
The activated middleware stores RunState by instance ID and removes entries only in on_error; successful runs are never cleaned up. Long-lived harnesses can therefore accumulate candidate paths and flags indefinitely, allowing request-controlled state to grow with each completed run. Remove the entry when the run finishes successfully as well as on errors.
Additional security observation
Handle skipped clock bands before emitting the late note
[RULE] preserve-clock-band-transitions
When the first observed tool result is already in the late band, the middleware emits the late note and returns without evaluating the half-time band. This permanently skips the half-time deliverable warning for turns with sparse tool activity, contrary to the documented clock-driven rungs. Process any crossed earlier band before marking and emitting the late note.
Additional security observation
Do not classify user messages by marker substring
[RULE] avoid-marker-based-input-classification
The activated middleware excludes any user message whose text contains <harness_instruction>. A user can include that literal substring and prevent candidate extraction for the turn, bypassing the unmet-deliverable hold. Distinguish harness-generated messages by their message metadata or role/source rather than searching untrusted text.

Accept extensionless deliverable paths
This parser only considers absolute paths whose final segment passes has_extension, so a request to write an extensionless deliverable such as /workspace/manifest is silently ignored and the hold never runs. A filename extension is not a reliable indication that a path is a file; accept plausible absolute path tokens independently of their suffix, while retaining the existing length and candidate-count bounds.
[RULE] extension-based-path-classification ·
There was a problem hiding this comment.
By design, documented on candidate_paths: an extension is what separates a file the request asks for from a directory or a sentence fragment, and this middleware prefers reporting nothing to guessing. An extensionless deliverable is not held; the other rungs (budget notice, writer belt, finish check) still apply.

Restrict deliverable existence checks to the workspace
The existence check uses each user-supplied absolute path directly, relative to the process filesystem, with no workspace restriction. A request can therefore cause checks against arbitrary locations such as /etc/report.json or another user's /tmp file, and an unrelated pre-existing file can suppress the reminder. Resolve candidates within the run's workspace and reject paths outside it before checking them.
[RULE] workspace-path-confinement ·
There was a problem hiding this comment.
By design it stats the path the request names, where the core runs, and nothing else: no read, no traversal (.. is rejected), bounded count and length, and the only thing echoed back is the request's own string. The workspace is not a boundary the request is confined to: Terminal-Bench requests name /app/... and /tmp/... outputs, and a hold that ignored them would miss the cases this was built for.

Require a regular file before accepting a deliverable
Path::exists() returns true for directories, symlinks, and other filesystem objects. If /workspace/output.json is an existing directory, the middleware treats the deliverable as written and allows the final answer through. Check that the resolved path is a regular file (and apply the intended symlink policy) rather than only checking existence.
Additional tests observation
Require a regular file before accepting a deliverable
[RULE] deliverable-regular-file
Path::exists() is true for directories and other non-regular entries, so a turn that creates a directory at the named path silences the hold without ever writing the deliverable. Use symlink_metadata and require is_file().
Additional tests observation
Restrict deliverable checks to the workspace
[RULE] unconfined-path-check
missing stats any absolute path the request happens to name, including paths outside the turn's workspace and on other mounts. A request can probe the existence of arbitrary filesystem locations and get the result echoed back in an advisory notice. Filter candidates to the workspace root before statting.

Require a regular file before accepting a deliverable

Identify harness messages structurally, not by substring
Any genuine user message containing the literal <harness_instruction> is excluded from candidate extraction. For example, a user asking for /workspace/report while explaining that literal tag would produce no candidates and bypass the middleware. Distinguish injected harness messages by their message structure or metadata rather than treating a user-controlled substring as proof of provenance.
[RULE] marker-substring-classification ·
There was a problem hiding this comment.
The <harness_instruction> wrapper is this crate's own marker (wrap_harness_instruction), and the transcript has no structural role for harness-injected user messages. A genuine request that quotes the literal tag is excluded from candidate scanning, which costs at most one missed hold on that turn; a model-generated message cannot inject a path this way because only user-role messages are scanned.

- Around line 378-379: Make the half-time check in the affected test
deterministic: replace the fixed sleep with a controllable clock, or widen the
timing window enough that scheduling delays cannot push the call into the late
branch of after_tool. Keep the assertion focused on half-time behavior.

Accept deliverables without filename extensions
The candidate detector requires an extension, so valid requested outputs such as /workspace/Makefile, /workspace/output, or /workspace/Dockerfile are ignored. The middleware therefore cannot enforce its stated behavior for extensionless deliverables; path role must not be inferred from a filename extension.
Additional critique observation
Accept valid root-level absolute deliverables
[RULE] path-detection
This rejects every valid root-level file such as /report.json, because the only non-empty path segment is both first and last. A request can legitimately ask for a file directly under the filesystem root, so the middleware will never remind the model or hold its final answer for that deliverable. Remove the first == last rejection or otherwise distinguish a root-level file from a malformed token.
Suggested change for this observation (reference only)
if !has_extension(last) {
continue;
}
Additional security observation
Accept valid root-level absolute deliverables
[RULE] root-path-rejection
The first == last check drops /report.json, even though it is a valid absolute path. This causes a legitimate root-level deliverable to evade the middleware. Do not reject a path solely because it has one non-empty component; enforce the intended workspace restriction instead.
Additional tests observation
Accept extensionless deliverable paths
[RULE] heuristic-path-inference
The module exists because a turn ended with its named output file never written, but a request that says “write the report to /app/output/report” — no extension — is silently never checked: has_extension rejects it, so the hold and both clock notes never fire for it. The module docs argue the extension requirement avoids guessing, but the cost is that the exact failure mode this middleware was built for is missed on any request whose output path has no extension. Either accept a last segment without an extension (relying on the existence check, as the design already does for inputs), or document that this class of request is out of scope in a place that governs the behaviour, not just the extraction.

Remove completed runs from the state map
The state entry is removed only in on_error; successful runs remain in runs indefinitely. This leaks one RunState per completed instance and, if an instance ID is ever reused, reuses stale candidates and flags from an earlier turn. Clear the entry when the run completes successfully, not only on errors.

Accept extensionless deliverable paths
The test encodes the assumption that only paths with filename extensions can be deliverables. A valid output such as /app/output/report has no extension but is still an ordinary file path, so the middleware must not silently skip it. Replace this extension-based expectation with coverage for valid extensionless output paths. This is a pre-existing parser issue exposed by this new test, so it is marked late.

Make the fix tool create the requested deliverable
The test is described as permitting a fix, but this fake tool only returns "ok" and never creates missing. Consequently, the second answer is accepted even if the middleware fails to observe a successfully written file, and the test does not exercise the intended recovery path. Use a fake tool that writes the requested path before the second answer, then assert that the run succeeds because the file exists.
Additional security observation
Make the fix tool create the missing deliverable
[RULE] incomplete-test-fixture
The test claims to permit a fix, but its fake tool only returns text and never creates missing. The second answer can therefore pass because the middleware's one-shot hold was exhausted, not because the deliverable became a regular file. This does not protect the production path that should release the answer after a successful write; use a tool fixture that creates the requested file before the second model response.

Preserve valid trailing filename characters
The scanner only treats the narrow ASCII set in is_path_char as part of a path. A requested path ending in a valid filesystem character outside that set, such as /workspace/report~, is truncated or rejected, so the existence check may target a different path or miss the deliverable entirely. Tokenization should preserve valid filename characters rather than treating them as prose delimiters.

The core behavior is only effective when middleware ordering, model continuation, tool execution, and filesystem observation work together.

Make clock-band assertions deterministic
The test relies on fixed wall-clock sleeps to land in the half-time and late bands. CI scheduling can delay the first sleep past the late threshold, or otherwise shift the observations across a boundary, causing intermittent failures and undermining the coverage this test is intended to provide. Inject or control the clock, or use a deterministic clock abstraction instead of sleeping.
Additional critique observation
Avoid sleeping across clock-band boundaries
[RULE] time-based-flaky-test
This test depends on wall-clock sleeps to land in the half-time and late bands. Scheduler delays, machine load, or test parallelism can make the second call occur after the late band, or make the final call cross another boundary, causing the expected note to differ. The repository rules explicitly prohibit time-based flakes. Inject a deterministic clock or otherwise control the elapsed duration instead of using thread::sleep in an async test.

Accept valid root-level absolute deliverables
The test treats a valid root-level absolute file path as something that must be rejected. Root-level paths are still absolute filesystem paths and should be candidates when named as an output; keeping this case in the rejection fixture locks in a false negative.

No end-to-end test drives the unmet-deliverable hold on a live chat turn
install_unmet_deliverable changes what a user sees: on a root chat turn that names an unwritten output path, the first final answer is held and a notice is injected (response.continue_turn), and half-time/late notes are appended to tool results. The unit tests drive the middleware against a ScriptedModel, not the assembled harness a chat client reaches. The lexical candidates (chat-harness-subagent.spec.ts, agent-harness-behaviors.spec.ts) mention 'orchestrator' only in unrelated subagent-relay scenarios; none sends a request naming a missing output file and asserts the answer is held and then completed. A test would have to: boot the app (or Rust E2E lane), send a chat turn whose request names an absolute output path that does not exist, assert the assistant does not finalise with only prose, then write the file (or let the mock LLM emit a tool call that creates it) and assert the turn completes with the follow-up answer. None of the four CI e2e jobs exercises this path; they are all still PENDING, so nothing observed contradicts this.

The test relies on wall-clock sleeps and a claim about scheduler slop. Slow CI, system suspension, or load can move an observation across a threshold, making the assertions flaky; the std::thread::sleep calls also block the Tokio worker.

Handle skipped clock bands before emitting the late note
The half-time behavior is only exercised when a tool result happens in bands 5 through 7. If no tool result arrives in that interval, the first later observation emits only the late note and marks half_noted without ever reporting the missing deliverable.

Accept deliverables without requiring filename extensions
This test locks in the rule that only absolute paths with extensions are deliverables. Valid requested outputs can be extensionless, and a relative path may be resolvable in the configured workspace. Keeping this expectation makes the middleware silently skip unmet deliverables instead of holding the answer. Update the test and candidate extraction contract to recognize valid deliverable paths without inferring their role from an extension.

[RULE] invalid-path-contract
This test locks in rejecting legitimate deliverables such as /report.json and an extensionless path like /app/output/result.

Avoid sleeping across clock-band boundaries
The clock-band test depends on scheduler timing and uses blocking sleeps inside an async test.

Test the unmet-deliverable hold on a live chat turn
The hold is only exercised through after_model, where it mutates continue_turn and relies on the next model call to create the file. There is no end-to-end test driving a real chat turn through this middleware, so installation scope, message extraction, model-call limits, and continuation behavior are unverified together.

The middleware only injects an instruction asking the model to write the missing file; it does not ensure that a tool call or other action creates it. If the model ignores the continuation instruction, the next response can still end without the requested artifact, while fired prevents another hold. The continuation must be allowed to re-check and enforce the deliverable, or the completion path must verify the file after the requested fix turn.

Add the referenced unmet-deliverable module
middleware.rs declares mod unmet_deliverable and re-exports install, but crates/openhuman-core/src/agent/tinyagents/unmet_deliverable.rs does not exist at this commit. This call therefore leaves the crate with an unresolved module and prevents compilation. Add the module implementation (and its tests if required) before wiring it into the harness. This concern is late because the missing module declaration/file is outside the changed hunk, but it remains an unresolved blocking issue from the earlier review.

Accept deliverable paths without filename extensions
This declaration activates candidate_paths, which requires has_extension(last) before a path can become a candidate. Requests for valid outputs such as /workspace/report, /workspace/Makefile, or /workspace/.env therefore produce no missing-file notice and no unmet-deliverable hold, even when those files were requested and never created. Path existence and file type should determine whether a named path is a deliverable; do not require an extension.

Recognize relative deliverable paths
This declaration activates a parser that only accepts tokens beginning with / and explicitly documents that relative paths are ignored. A normal request such as write the result to output/report.json or save it as report.json therefore never gets checked, so the middleware cannot enforce the deliverable contract for the common relative-path form.

Drive clock-band tests with a deterministic clock
This async test blocks the test worker on a wall-clock sleep and assumes the scheduler will observe the run in the intended band. Under CI load, pauses or timer granularity can move the observation across a threshold, producing intermittent failures and unnecessarily tying up a worker for several seconds. Inject or control the clock used by the middleware in tests, or expose deterministic threshold advancement instead of sleeping.
Additional critique observation
Make clock-band assertions independent of wall-clock sleeps
[RULE] timing-dependent-test
The test depends on a 4-second real-time budget and assumes that 2.2 seconds reaches the half-time band and that a further 1.3 seconds reaches the late band. Scheduler delays, a loaded CI worker, or Tokio runtime starvation can move either observation into a different band and make the test flaky; std::thread::sleep also blocks the async executor thread. Use an injectable clock or deterministic context time instead of sleeping across thresholds.

Under scheduler or CI load these margins can collapse and move a call across a band boundary, producing flakes; the repository rule forbids time-based flakes. Inject a controllable clock (or fake the TurnClock) so the bands are exercised deterministically.

Identify harness messages structurally, not by substring
Filtering harness injections by checking that the text contains <harness_instruction> misclassifies any genuine user message that quotes or contains that marker, and breaks if the wrapper text changes. Use the harness's structural marker for wrapped instructions instead of a substring test on user text.

Restrict deliverable existence checks to the workspace
missing stats any absolute path extracted from the request, so a crafted or mistaken request makes the agent's middleware probe arbitrary host filesystem locations (e.g. /etc/...) and echo whether they exist back into the model context. Constrain candidates to paths inside the turn's workspace before statting.
[RULE] unbounded-path-stat ·
A turn already carries four rungs that tell the model to produce its
deliverable -- the budget notice part-way through, the penultimate call's
narrowed writer belt, the concluding instruction, and the requirements check
-- and the orchestrator prompt states the rule as well. All five are advice,
and none of them looks at whether anything was written, so a turn that
ignores them ends with a careful account of work nobody can use.
One run reconstructed a transcript, catalogued eleven variants and resolved
the domain it was asked for, listed the output file in its own answer as
"still outstanding", and stopped. Every check that read that file failed on
its absence rather than on anything in it. An earlier run of the same request,
which wrote a partly-filled file, was judged on the contents.
Hold the first final answer once when the request named a file that does not
exist, and say which path, with an instruction to write what has been
established even where it is provisional.
Telling a named output from a named input needs no grammar. The existence
check does it: a path the request gives as an input is already on disk and is
never reported, and a path nothing has created is either a skipped deliverable
or a passing mention, where the cost is one sentence. Extraction is therefore
deliberately blind -- absolute paths with a file extension, deduped, bounded,
never traversing -- and existence decides.
Existence only: nothing is opened or read, the paths echoed back are the ones
the request already carried, and a file holding `{}` satisfies it. Scope
matches the requirements check (root orchestrator turns), and the notice is
given once per turn whatever the second answer looks like.

…isfied both ways Two clock-driven notes on the tool result the model is about to read: at half the turn's budget, a path the request names that still does not exist is pointed out with the instruction to write it now and improve it in place; at 80%, to stop exploring and make what exists meet every limit the request states. Each is given once per run and asks the loop for reasoning on the next call. One run spent eight of nine minutes probing an input format, wrote the program at minute fourteen of fifteen, and had no time left to meet the size limit it knew about. Orchestrator and finish check: where the request describes one thing two ways (an argument called a folder in one sentence and the file to save in another), implement so every reading is satisfied and test each; a path value with a file extension is that file. One run wrote a directory where the grader expected a CSV and six tests died on it.

Its half-time and late notes read the clock from the run context, which does not carry the wall-clock budget; the sibling time-note middlewares receive it from the harness policy at construction. Same now, so the notes fire: on the first run neither did. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> (cherry picked from commit 5f94e071ec7cca7b552bcc5ca1b19668f2827616)
`unmet_deliverable::install` mirrors `verify_before_finish::install`: the same root-orchestrator scope and the policy's wall clock, in one call from the assembly, which keeps `harness_assembly.rs` under the layout limit. A test covers the install on a root turn and on a sub-agent turn. The half-time and late notes no longer ask the loop for reasoning on the next call: the vendored tinyagents has no such request yet (tinyhumansai/tinyagents#342 adds it); the line returns with that gitlink.

…allows a file that lives elsewhere Review follow-ups. A URL's `//host/file.ext` was read as a rooted path: a `/` after `:` or before another `/` no longer starts a token. The candidates come from the current turn's request (the last user message on the first call, harness instructions excluded), not the thread's first message, which could be an earlier turn. The notice now says the file does not exist here and that a path to a file on another machine or in a container can be answered as such; the hold is still given once. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
A path the request names may be a file on another machine or in a container; the note now says the write applies when the path is the file this turn was asked to produce, and otherwise to say so in the answer. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
A directory written at a `.csv` path is as unmet as nothing at all, so the existence check asks for a regular file. The half-time and late notes get a test that drives the clock through both bands and checks each note is given once. The request's paths are logged at debug. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
A run whose first tool result arrives past 80% got the late note and then, on the next result, the half-time note. The late branch now marks both as given and the half-time branch applies only below the late band. The clock test's budget is 4 s so a second of scheduler slop cannot move a call across a band; a late-first case is tested. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…og counts The run entry left the map only on an error, so a normally finished turn kept one. It is now dropped in after_agent too, with a test.

Drive the late-band assertion deterministically
This second blocking sleep has the same wall-clock race independently of the earlier assertion. A slow or busy CI worker can move the observation across multiple bands, while a fast or suspended worker can produce different note behavior than the test expects. Use an injectable clock or deterministic timestamps for the late-band transition.

Accept valid root-level and extensionless deliverables
This rejects /report.json because it has only one segment, and rejects every valid filename without an extension such as /README or /output. Filename extensions and directory depth are not reliable indicators of whether a request names an output file, so these deliverables are never checked.
Additional critique observation
Recognize relative deliverable paths
[RULE] path-form-rejection
Relative paths such as artifacts/report.json are never candidates because scanning only starts at /. Requests commonly name outputs relative to the agent workspace, so this causes the hold to be skipped for valid deliverables.
Additional critique observation
Accept valid root-level absolute deliverables
[RULE] root-path-rejection
A valid root-level path such as /report.json is rejected because first == last for the sole non-empty segment. The parser therefore misses deliverables that are intentionally placed directly at the filesystem root.

Make the scripted fix actually create the deliverable
The end-to-end test claims that the model is allowed to fix the missing output, but its fake writer only returns ok and never creates missing. The second answer therefore passes because the middleware's one-shot fired state permits it, not because a tool wrote the requested file. Make the scripted tool create the exact path and assert that the file exists, otherwise this test cannot catch a broken fix path.

Reject both slashes of URL separators
This skips the first slash in https://host/report.pdf, but then the second slash is treated as the start of a local absolute path (/host/report.pdf). That can produce false deliverable candidates and, before workspace containment is enforced, cause filesystem probes based on URL text. When a slash is part of :// or follows another slash, advance past the separator rather than rescanning the second slash.

Do not infer path roles from filename extensions
This instructs the orchestrator to treat every extensionless value as a directory and every dotted value as a file. That rejects legitimate extensionless deliverables such as Makefile, LICENSE, or README, and can turn a requested dotted directory such as data.v1 into a file. Path role must come from the request's explicit contract or filesystem/tool semantics, not from the presence of a dot in the name.

Do not lock in extension-based path classification
This assertion makes the archetype's rule that a path without a file extension is a directory part of the tested contract.

Do not infer deliverable paths from filename extensions
The extension requirement is the only classifier between a deliverable and a mention, and it is now also written into the prompt and the requirements check as a rule the model must follow ('a path argument whose value has a file extension is a file, one without is a directory'). That is a heuristic, not a contract: many named deliverables are extensionless (out/Makefile, /app/output/RESULTS, /tmp/run-report), and a run naming one of those is never held, which is exactly the failure the module exists to catch. The same reasoning applies at the other end — a . in a mention (v1.2/notes) passes the extension test and can hold a turn that was never asked to write. None of these cases is in the test module's accepted or rejected lists. As before, this keeps its level; the change is new only in that the prompt now states the heuristic as a rule.

Do not infer path role from filename extensions
This tells the orchestrator to treat a path containing a filename extension as a file and to prefer that heuristic over the request's prose. That misclassifies valid directory names such as fixtures.v1 and can reject or mishandle extensionless output files when the explicit contract says what the path represents. Resolve contradictions using the request's executable evidence and explicit path semantics, not filename syntax.

Do not infer deliverables from filename extensions
Still only paths with an extension qualify as candidates, so a request naming /app/output/report or a relative deliverable like output/report. is never checked and the hold never fires for it. The module doc presents the extension as a heuristic; nothing in the tests pins that a real deliverable without one is out of scope, and the skipped-deliverable failure mode this middleware exists for recurs whenever the request's path is extensionless or relative. Consider accepting any multi-segment absolute token, or at least also scanning the last user message for relative paths joined against the turn's working directory.

Identify harness messages structurally, not by substring
The last-user-message scan still classifies messages by a literal marker substring. A user request that legitimately quotes or contains <harness_instruction> (e.g. reporting a harness bug, pasting a log) would be silently skipped as a candidate source, and any change to the wrapper's wording breaks detection quietly. The message type or a structured role/source field should carry this, as raised in earlier cycles.

Recognize relative deliverable paths
Candidates must be absolute; a request that names its output relative to the workspace (write the report to output/results.) is never held even though it is the same unmet-deliverable failure the module was built for. The middleware already runs in a turn with a defined working directory, so resolving relative tokens against it is feasible; if it is deliberately out of scope, a test asserting that behaviour would at least pin the boundary.

… for reasoning again Moves vendor/tinyagents from 1df6ad01 to 5d322814, the merge of tinyagents #343, which carries exactly tinyagents #342 (dead-call recovery: reasoning-off fallback after a dead call, the streaming reasoning watchdog, the dead call's reasoning carried into the retry, reasoning handed back on a repeat note and for the finish check) and #343 (vendored tinytools to e2bf1be: tinytools #52 to #56). tinytools e2bf1be moves tinytools-std to sha2 0.11, so Cargo.lock records that; no other dependency changes. With RunContext::request_reasoning now in the vendored harness, the half-time and late notes ask for reasoning on the next call again, as they did before #7145 had to drop the calls. The clock-band test asserts both requests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Summary
Four commits, each self-contained. Together: a turn that never wrote the file its request named is held once; a requested file still absent at half the turn's budget is pointed out on the tool result the model is about to read, and at 80% the note says to stop exploring and meet the stated limits; and where a request describes one thing two ways, the orchestrator and the finish check ask for a result that satisfies every reading.
Problem
A turn carries four rungs that tell the model to produce its deliverable (budget notice, writer belt, concluding instruction, requirements check) and none that looks. One run catalogued everything it was asked for, listed the output file in its own answer as "still outstanding", and stopped; every check failed on the file's absence. Another spent eight of nine minutes probing an input format, wrote the program at minute fourteen of fifteen, and had no time left for the size limit it knew about. A third wrote a directory where the grader expected a CSV because the request called the argument a folder in one sentence and the file to save in another.
Solution
feat(agent): hold a turn that never wrote the file its request named—UnmetDeliverableMiddleware: absolute paths with a file extension are extracted from the request, deduped and bounded; a path that does not exist when the first final answer arrives holds that answer once, naming the path. Existence only; nothing is read. Scope matches the requirements check (root orchestrator turns).agent: a deliverable by half-time, and a request read two ways is satisfied both ways— the half-time and late notes, appended once each to a tool result; the orchestrator bullet and finish-check step 3 on satisfying every reading; where one path cannot be both, the evidence decides in order (the request's own test or example call, then the form of the value, then the prose label last).agent: hand the deliverable middleware the turn's clock budget— the notes read the clock from the run context, which does not carry the wall-clock budget; the harness policy'smax_wall_clock_msis passed at construction, as the sibling time-note middlewares do. Without it neither note fired.agent: install the deliverable check from its module—unmet_deliverable::installmirrorsverify_before_finish::install(sameappliesscope, policy budget), which keepsharness_assembly.rsunder the layout limit. The notes no longer ask the loop for reasoning on the next call: upstream tinyagents has no such request yet (agent_loop: dead-call recovery: a reasoning watchdog, reasoning switched off after a death and back for repeats and the finish check, and the dead call's reasoning carried into the retry tinyagents#342 adds it); the line returns with that gitlink.Evidence (Terminal-Bench 2.0, deepseek-v4.1-flash, one trial each unless stated)
gpt2-codegolf: with the note the program existed at minute 6 of the 15-minute budget instead of minute 12 (first run never had the note fire, which is the third commit). The task still failed in both trials: the file was 6,290 bytes against the task's 5,000-byte limit, and correctness work consumed the rest. The note changes when the deliverable exists, not whether the model can meet the limit.sam-cell-seg: before the rule, the script wrote a directory at the CSV path (IsADirectoryError, 3 of 9 tests passed). In two trials with the rule the script failed earlier, at argument parsing, because the model implemented the four named arguments positionally while the grader passes--name value, so whether the path reading improved is not observable in those trials. A further rule on named flags was tried on one run, did not change that, and is not in this PR. Treat this bullet's benefit as untested.Submission Checklist

Root orchestrator turns only. One extra model call at most when a named file is missing at the first answer; two short notes appended to tool results at 50% and 80% of a turn with a wall-clock budget. No change for turns without a budget beyond the hold.
