feat(githooks): canonical docstring scanner with a known-answer suite - #1073
Merged
Merged
Conversation
Adds .githooks/docstring-scan.sh. It asks the same question as CodeRabbit's "Docstring Coverage" check: of the functions a change touches, how many carry a docstring? It answers per function with added/modified provenance, and in --check mode it blocks only on a newly-added undocumented function. The Stop hook, the pre-commit validator and the CI backstop all consume it. Tier 1 is shell. Every other source file reports as SKIPPED, never as documented, and the SUMMARY line always prints its denominator. scripts/tests/docstring-scan-test.sh (30 assertions) calibrates against PR #1034 at 1cc72cd (2 files / 13 functions / 0.00% / 3 skipped). If that commit is absent, the calibration fails rather than skipping. The suite also covers: - a planted positive and a negative control; - added vs modified; - predicate edges (trailing comment, shellcheck directive, heredoc body); - --staged/--worktree parity; - paths containing spaces or non-ASCII characters. These mutants were each killed: a shellcheck directive counted as a docstring, a heredoc body treated as code, untracked files dropped, a trailing comment counted as a docstring, and a deleted fixture docstring.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Extensionless shell scripts are skipped in --staged and --range modes.
The shebang check runs only when MODE is worktree. It also reads the worktree file, not the new content for the active mode. For example, a staged .githooks/pre-commit with #!/usr/bin/env bash is classified as other and reported as skipped. The pre-commit gate and the CI gate then miss new undocumented functions in hook files. The --worktree report for the same change classifies the file as shell. This breaks the staged/worktree parity that the PR claims.
Read the first line with new_content for every mode.
🐛 Proposed fix

Resolve SCANNER to an absolute path before changing directory.
With SCANNER=.githooks/docstring-scan.sh, the existence check passes when the suite starts at the repository root. After newrepo changes directory, scan looks for that relative path inside the fixture repository. The scanner cannot run, so the fixture assertions fail.
Resolve the override to an absolute path before the first directory change.

Clear inherited Git environment variables before running Git.
If a caller exports GIT_DIR for another repository, git init uses that directory instead of creating the fixture's .git. The subsequent git config commands can then change the caller's repository configuration. Changing directory does not remove this override. (git-scm.com)
Clear repository-local Git environment variables at startup, before calibration and fixture setup.
Based on learnings: scripts that invoke Git must clear inherited repository-local Git environment variables.

The calibration commit 1cc72cd is PR #1034's pre-squash head. It lives only under refs/pull/1034/head, so no clone of main contains it and Self Test has been red on main since #1073. Fetch it by full SHA when absent, with no --depth, since that would make a complete clone shallow. Keep the fail-closed assertion when the fetch fails.

…uuid-v7, map roots, canon 2.1.2, docstring calibration (#1088) Restores `standards` main to green. The reds on main and on this PR hold each other in a cycle, so every cure is in this one PR: under the fully-green rule, no smaller PR can pass CI alone. ## What each commit fixes 1. **Lock-gate staging pin bump.** The `ref:` under "Checkout standards for the lock gate" in `governance-reusable.yml` moves to `5f82b635`. `scripts/check-lock-gate-pin-freshness.sh` returns rc=1 on main and rc=0 on this branch. Each tree's own copy of the script was run; running one tree's copy against another tree reads the wrong workflow and passes vacuously. 2. **Registry `source_hash` regeneration** (#1092). #1072 and #1075 changed files under the RSR spec home without regenerating `.machine_readable/REGISTRY.a2ml`, so `build-registry.sh --check` fails. That failure reds Self-tests, and the pin guard step never runs because it comes after the failing suite. The change is one regenerated hash line. Under D231 it is a regeneration only; migrating off the generated file is a later piece of work. 3. **`uuid-v7.yml` hardening.** It adds `timeout-minutes: 10`, a `concurrency` group, and a `push` trigger bounded to `main`. These are the three unfiltered Hypatia Baseline findings on main: missing_timeout_minutes, d_burn_double_trigger, and WH006. 4. **Delete the five unmapped root entries** (D241, cherry-picked and signed from #1097). This cures the map-integrity red that woke on this PR. 5. **Canon PATCH 2.1.1 → 2.1.2.** #1041 added a KNOWN-TENSIONS row under `0-canon/constitution/` without the same-commit bump and sha256 rewrite that `canon.lock` requires. Gate A is path-filtered, so main never ran it and the drift stayed invisible until this PR woke the gate. This commit bumps the version, sets released to 2026-09-30 and the tag to `canon-v2.1.2`, rewrites the constitution hash to `be48496f…`, and adds a header note. The spine's dogfood red was a stale hypatia compile error, fixed upstream at 9d2e6de3. Re-running rsr-template-repo run 36475038466 turned it green. 6. **Fetch the docstring calibration commit by SHA** (#1099). #1073's `docstring-scan-test.sh` calibrates against `1cc72cdc80c9`, PR #1034's pre-squash head, which no clone of main can contain. Self Test on main (run 36741131926) failed on this as well as the stale registry. I read only the first failure, so my earlier claim that this PR cured every main red was wrong. The test now fetches the commit by full SHA on a miss, without `--depth` (which would make a complete clone shallow), and still fails closed if the fetch fails. The branch was rebased onto main 74d2f66 (signed) so the test file is present. Closes #1092 Closes #1094 Closes #1095 Closes #1099 ## Local verification on 6192c92 (rebased on main 74d2f66) | check | result | |---|---| | `bash scripts/run-shell-test-suite.sh` | 63 of 63 test files passed | | `check-lock-gate-pin-freshness.sh origin/main` | PASS | | `build-registry.sh --check` | clean | | `check-canon-lockstep.sh --spine rsr-template-repo@8256a6e --base origin/main` | GATE A PASSED (9 passed, 1 skipped: hypatia oracle not local) | | `check-standards-map.sh` | GATE D PASSED, 124 entries | | **positive control:** one appended byte in `KNOWN-TENSIONS.adoc`, `canon.lock` untouched | GATE A FAILED, naming `constitution` | | docstring calibration: watched failing locally (object absent, 25 passed / 1 failed), then green after the fix | files=2, functions=13, documented=0, skipped=3, coverage=0.00%; clone not shallow afterwards | #1097 is superseded by commit 4.

) ## What Adds **leg B** to the canonical docstring scanner `.githooks/docstring-scan.sh` (#1073): - **Leg B**: documented / (documented + undocumented) over **all touched** (added + modified) functions, skipped files excluded, below `DOCSTRING_THRESHOLD` (default **80**) is a violation. This is the ratio CodeRabbit's Docstring Coverage check reports. - **Phase-in**: a self-flipping date gate with the same shape as `scripts/check-docs-presence.sh` (`valid_date`/`require_date`, plus a `DOCS_TODAY` seam). `ENFORCE_DOCSTRINGS_FROM` defaults to **2026-11-01** (owner ruling 2026-10-01). Before the cutoff, a leg-B violation under `--check` prints a `WARN leg B` line on stderr and leaves the exit code unchanged. From the cutoff date onward, `--check` exits 1. - **Leg A is unchanged**: an added undocumented function still makes `--check` exit 1. - **Zero touched functions** gives `legb=n/a`, and under `--check` the scanner says so on stderr. A vacuous ratio counts as neither a pass nor a fail. - **Fail loud**: a malformed `ENFORCE_DOCSTRINGS_FROM` or `DOCS_TODAY`, or a `DOCSTRING_THRESHOLD` that is not an integer 0-100, exits **2** in every mode. A bad value cannot silently disarm the gate. - **Integer verdict**: the check is `d*100 < T*n`, so exactly 80% passes and 79.17% fails. - **SUMMARY** gains `threshold=T legb=pass|fail|n/a`, appended at the end only. The one consumer I found is the `~/.claude` docstring Stop hook. It drops the SUMMARY line, reads only `added`/`undocumented` TSV rows, and runs **without** `--check`, so this PR changes nothing for it. Nothing in this repo parses SUMMARY apart from the test suite. ## Tests (`scripts/tests/docstring-scan-test.sh`): 72 passed, 0 failed locally. The full `run-shell-test-suite.sh` passed all 63 files. - The existing leg-A assertions now run with leg B disarmed (`DOCSTRING_THRESHOLD=0`). Without that, "editing an undocumented legacy body does not block" would flip red on 2026-11-01. - New fixtures cover: - before the cutoff: WARN and rc 0 - on the cutoff date and after it: rc 1 - `ENFORCE_DOCSTRINGS_FROM` override - no `--check`: rc 0 - exactly 80% passes; 79.17% fails - zero touched: no verdict, rc 0 - skipped files in both directions: 3/4 fails beside a skipped file, which would read 4/5 if skipped counted as documented; 4/5 passes beside a skipped file, which would read 4/6 if skipped counted as undocumented - malformed dates and thresholds: rc 2 - **Known-answer calibration controls.** Each one fetches commits by full SHA into a throwaway repo, and an unfetchable commit counts as a FAILURE ("a skip is not a pass"). Both match CodeRabbit's verdict at the head it reviewed: - `hyperpolymath/panll` `964f9563..61141fb3` gives **2 documented of 22**, legb=fail. - `hyperpolymath/nextgen-databases` `fc12a2eb..e12e4c71` gives **2 documented of 22**, legb=fail. - Leg A also fires on both ranges (9 added undocumented each), so these controls assert SUMMARY fields, not exit codes. ## Mutants (run through the `SCANNER=` seam; each passed `bash -n` and differed from the original under `cmp`) | Mutant | Reds | |---|---| | ratio `-lt` → `-le` | 4: the two exactly-80% fixtures (each asserts verdict and rc) | | date compare `<` → `>` | 6: before-cutoff rc0 and WARN, after-cutoff, ENFORCE override, 79.17% rc, skipped rc | | skipped counted as undocumented in the denominator | 2: 4/5 passes beside a skipped file (verdict and rc) | | skipped counted as documented | 2: 3/4 fails beside a skipped file (verdict and rc) | A planted bad calibration SHA reds the control as `commits present … absent`. shellcheck is clean, and both files stay 0755. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01Hw7qg3u9PAP6b2oKyVTSVC Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
