Summary

  • integrate the remaining Nyarlathotep/pre-commit toolchain branches into one reviewable head
  • isolate parent/runtime shims and managed caches, preserve exact staged-file trust, and make gate exit handling fail closed
  • carry portable actionlint-to-ShellCheck metadata, validated UV environments, policy-git aliases, and the corresponding docs/tests
  • close the concrete CodeRabbit findings on the prior PR head

Validation

  • Python test suite: 50 passed through the canonical gate
  • make lint
  • make go-test
  • full commit and pre-push hooks on head 5a803de
  • docs/examples updated for changed behavior

Capability Surface

  • chosen surface: Go hook/runtime, policy/CEL integration, generated toolchain configuration, and documentation
  • why this surface owns the behavior: critical commit, lint-capture, sandbox, and parent-integration behavior is implemented by the compiled Go runner; generated configuration remains derived from repository authorities
  • grounding docs, metadata, policy IDs, tool definitions, or command docs: docs/HOOK_RUNTIME_BOOTSTRAP.md, config.yaml, repo_ethos.yml, and go/toolcatalog

Checklist

  • scope is intentional and limited to this integration and directly caused cleanup
  • tests updated when behavior changed
  • README / templates / config docs updated when workflow changed
  • no secrets or local-only paths introduced
  • CLA Assistant check completed

Notes

The outer agent sandbox prevents the complete local make check/make build paths from writing generated Gemini and code-intelligence artifacts, and it denies nested copied executables. The enforced commit and pre-push hooks, managed lint group, managed Go suite, and Python suite passed. The remaining local messages are nonblocking sandbox cache/code-intelligence warnings and the visible below-90%-coverage goal warning; GitHub CI supplies the consumer-visible final gate.

The branch also moved related shell/Python integration behavior into compiled Go where practical: actionlint marker handling, policy-git argument handling, gate status classification, and managed cache/environment setup now live in the Go runtime.

Review Change Stack

📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Git hooks now use a stable, verified runtime independent of worktree locations.
    • Repository gates are blocked when shell commands hide or alter their final status.
    • Generated configuration files are recognized when staged content exactly matches approved output.
    • PII scanning supports configurable path exceptions, including /home/agent/.
  • Bug Fixes
    • Improved parent workflow checks, hook synchronization, and external environment handling.
    • Code Intelligence upgrades deduplicate legacy search data while preserving related code relationships.
    • Improved Git command option parsing and managed tool routing.
  • Documentation
    • Updated workflow and hook-runtime guidance.

Walkthrough

The pull request updates the shared hook runtime, adds exit-status enforcement, introduces staged generated-file verification, upgrades Code Intelligence storage to schema v2, improves policy Git parsing, and adds PII, shell, UV, and memory handling changes.

Changes

Runtime, policy, and data integrity

Layer / File(s) Summary
Stable hook runtime projection
Makefile, go/cmd/coding-ethos-run/..., go/internal/hookrunnercli/..., docs/..., pre-commit/...
Parent workflows install and verify executable projections in the Git-common runtime. Hooks use explicit runners, repository-owned Go and UV state, and stable temporary roots.
Code Intelligence schema and replay integrity
go/internal/codeintel/..., docs/CODE_INTEL.md
Schema v2 adds unique search identities, duplicate migration, migration accounting, conflict-aware upserts, and search-term synchronization.
Generated-file trust and evaluator configuration
go/internal/generatedtrust/..., go/internal/lint/..., go/internal/evaluators/..., go/internal/policy/..., config.yaml, repo_config.example.yaml
Staged generated files are trusted only when their Git-index bytes match authority-rendered artifacts. PII and shell evaluator behavior now uses configured repository state.
Required gate exit-status enforcement
go/internal/hooks/gate_exit_status.go, go/internal/policy/...
A Bash policy blocks required gates whose exact exit status is masked by shell control flow, pipelines, wrappers, or nested scripts.
Command parsing and bounded project identity
go/internal/policygitcli/..., go/internal/memories/...
The policy Git wrapper separates wrapper options from Git arguments. Claude project keys use bounded, UTF-8-safe deterministic truncation.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 5a803

This PR hardens hook execution and shared runtime behavior, but the current head can still allow a required gate failure to be hidden after set +o pipefail, and concurrent hooks may observe partially replaced executables; these can permit invalid changes or interrupt hook execution, so the PR should not merge until the gate-state bug and installation safety are addressed.

Poem

A rabbit checks the hooks at night
Hashes glow in common light
Search rows settle, neat and small
Gates return their status call
Config paths pass the guard
Safe builds hop across the yard

Use the stable parent runner for the shared git shim.

installGitShim embeds --runner in the installed shim as exec <runner> policy-git "$@". Line 681 passes checkout-local $(GO_HOOK), so parent Git commands can fail after the authority checkout is retired. Pass $(PARENT_HOOK_BIN_DIR)/coding-ethos-run instead.

Inline comments:
In `@go/cmd/coding-ethos-run/dispatch.go`:
- Around line 1043-1044: Update parentExecutablePath() and the related
ShellCheck routing so actionlint requests using “shellcheck -f json -” directly
invoke the managed ShellCheck executable on supported non-Linux runtimes, while
preserving the existing Linux behavior. Use a portable parent-process signal or
an explicit actionlint dependency marker to distinguish this path from ordinary
runtimeExecLint handling.

In `@go/internal/generatedtrust/staged.go`:
- Line 37: Update ExactStagedFiles in go/internal/generatedtrust/staged.go at
lines 37-37 to intersect normalized caller paths with paths from git diff
--cached --name-only --diff-filter=ACMR before returning trusted paths, ensuring
only changed staged files receive the exemption. Add a regression test covering
an unchanged generated file. Review go/internal/lint/runner.go lines 148-158,
go/internal/lintcli/main.go lines 475-480, and go/internal/mcp/server.go lines
441-445 to ensure their callers use the corrected membership result; these sites
require no separate behavior change unless needed to preserve that root-cause
fix.

In `@go/internal/hooklog/runner.go`:
- Around line 264-266: Update the Code Intelligence ownership comment near the
hooklog runner to accurately state that it refreshes only policy-lint, git-hook,
and make commands, while parent-install, parent-check, and parent-lint do not
call codeintel.RefreshRepository.

In `@go/internal/hookrunnercli/external_tool.go`:
- Around line 324-325: Update the external-tool environment setup for
UVProjectEnv and UVFrozen so hooks do not all share a forced frozen mode or the
same repository-level environment. Scope these variables to the active UV
project, using a distinct project-specific environment and only enabling frozen
behavior where that project requires it.

In `@go/internal/hooks/gate_exit_status.go`:
- Line 67: Update the shell-segment processing around inheritedPipefail and
parsed.enablesPipefail so pipefail is evaluated and propagated in execution
order rather than scanning the entire parsed command upfront. Ensure each
pipeline uses only the pipefail state active at that segment, so a later set -o
pipefail does not affect earlier pipelines.
- Line 58: Update maskedRequiredGateStatus to return a blocking result when
depth exceeds maxGateShellDepth, rather than treating the command as unmasked
and allowing requiredGateExitStatusRouteFor to proceed. Preserve the existing
handling for blank commands and commands within the nesting limit.
- Around line 481-483: Update the pytest case in requiredExecutableGate to use
isPythonCommand for executable matching, so versioned interpreters such as
python3.12 are recognized while preserving the existing -m pytest argument
validation.

In `@go/internal/policygitcli/main.go`:
- Around line 248-252: Update the gitGlobalOptionStartsArgv allowlist used by
parsePolicyGitArgs and consumeWrapperOption to recognize Git’s short help and
version aliases, -h and -v, alongside their existing long forms; verify the
allowlist matches the supported Git version’s global options without changing
unrelated argument handling.

665-667: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Install projected executables atomically.

A concurrent hook can execute a destination while cp truncates and rewrites it. The hook can then fail before the copy completes. Copy each executable to a temporary file in $(PARENT_HOOK_BIN_DIR), set its mode, and rename it into place. This violates the documented atomic-install contract for the shared Git-common runtime.

Proposed fix
-	`@cp` "$(GO_TOOLS_BIN_DIR)"/coding-ethos-* "$(PARENT_HOOK_BIN_DIR)/"
+	`@for` source in "$(GO_TOOLS_BIN_DIR)"/coding-ethos-*; do \
+		target="$(PARENT_HOOK_BIN_DIR)/$$(basename "$$source")"; \
+		tmp="$$target.tmp.$$"; \
+		cp "$$source" "$$tmp"; \
+		chmod 755 "$$tmp"; \
+		mv -f "$$tmp" "$$target"; \
+	done

Handle set +o pipefail in maskedRequiredGateStatus.

isPipefailCommand only recognizes set -o pipefail, so the state remains true after set +o pipefail. A later required gate pipeline can therefore bypass gatePipelineReason and mask the gate failure. Track both operations.
