Summary

just check (and the queue's just ci) now fails a branch that edits any MIGRATE.md, unless that file's diff adds a version-transition heading (## 0.3 -> 0.4), which is how the release cut writes it. The error tells the author to revert and put the note in the PR's Impact section.

• sh/migrate.sh: diffs against the merge base from sh/changed.sh, so it holds in the merge queue as well. It runs only when a MIGRATE.md changed, and is skipped under --all, where there is no diff.
• sh/migrate.test.py: tests against a scratch repo, wired into .github/justfile.
• AGENTS.md keeps one line on where the note goes; CONTRIBUTING.md's Releases section says the version section is the only MIGRATE.md edit the check allows. Its Impact line already says a behavior change alone takes no !.
• Deletes quest/m0/ci/migrate-guard.md and its link.

Impact

Public API: none. Wire: none.

Choices made without asking

• How the cut is recognized: by content, meaning the file's diff adds a ## A -> B heading, rather than by branch name. Merge-queue refs lose the branch name, and the cut lands on main from an arbitrary branch. Trade-off: once a file's diff adds such a heading, the check allows any other edit to that file too. The guard is meant to catch accidental notes, not to resist someone gaming it.
• Several guides still have ## Unreleased sections from earlier PRs. The next cut folds them into its version section, so this PR leaves them alone.

Checks

shellcheck, shfmt, ruff, sh/text.sh, sh/migrate.test.py, sh/dispatch-query.test.py, and sh/migrate.sh origin/main all pass. The full quest gate just check waited about 90 minutes for host load and never started, so CI is the full gate.

Follow-ups

None.

Automated review by review (OpenAI)

Reviewed the complete patch at 8e43757, the shared merge-base resolver, dispatcher selection/execution, and existing review context. No actionable findings.

Direction: the small diff-based guard fits the accidental-edit problem. It checks each guide independently, preserves enforcement when orchestration changes widen the run, and skips only an explicit --all. Recognizing a cut by an added transition heading is deliberately permissive, as documented.

Verification limits: GitHub-only static review. I did not execute tests, just check, or a merge-queue run; reported author checks were not independently verified.

Walkthrough

The change adds sh/migrate.sh to check changed MIGRATE.md files for an added version-transition heading. The dispatcher runs the check for matching paths, except when the selected base is --all. New tests cover committed and uncommitted changes. The release guidance now describes the permitted version-transition edit, and the migration-guard planning document was removed.

Merge Risk: Low · previous review 8e437

The migration guard can be bypassed by adding a non-version heading, or by editing older sections alongside a valid one. This is a CI-only check with no runtime impact. Tighten the pattern before relying on it to enforce the release-cut rule.

Full details: Docstring Coverage

Explanation

Docstring coverage is 33.33% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 4 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

older sections even when the diff contains a matching new version-transition
heading; accept the file only when edits are confined to the new section, as
required by CONTRIBUTING.md.
- Line 18: Update the heading pattern in the `grep` check to require a version
on both sides of the transition arrow, while allowing package names alongside
those versions; keep the existing diff filtering and heading check behavior.

Important

The guard is correct for the small diffs the tests cover, but a large MIGRATE.md diff that does add a version heading is a false positive. sh/migrate.sh:18 runs git diff ... | grep -qE ... under set -o pipefail: grep -q exits on the first match, git diff gets SIGPIPE, and the pipeline's non-zero status is treated as "no heading". I reproduced it with a scratch repo whose MIGRATE.md changes more than the pipe buffer: the release cut's own edit is rejected with error: only the release cut edits MIGRATE.md. A release cut that rewrites a large guide while adding the heading would be blocked.

The fix is to read the diff through a process substitution, so the grep's exit status is the only one that matters: grep -qE '^\+## .+ -> .+' < <(git diff --no-renames -U0 "$base" -- "$path"). Add a test case with a large diff, since the existing four cases only exercise small diffs.

The rest of the PR is sound: the guard runs only when a MIGRATE.md changed, the --all skip is explicit, the sh/dispatch-query.test.py stub covers the widened run, and the AGENTS/CONTRIBUTING wording matches the enforcement.

Automated review by review (OpenAI)

Reviewed update 900dd0a against previously reviewed 8e43757. GitHub comparison shows one additional commit changing only sh/migrate.sh:18; the current PR base is cd560bd.

No new actionable defects found. Process substitution makes the condition depend on grep's status, resolving the large-diff SIGPIPE false rejection identified by the other reviews. The deliberately permissive release-heading policy is unchanged. Overall direction: this focused correction looks sound.

Non-blocking verification suggestion: add a regression case to sh/migrate.test.py with a matching heading followed by a diff larger than a pipe buffer, so the original pipeline form cannot silently return.

Verification limits: GitHub-only source/diff review; no tests or merge-queue run executed.

[pullfrog]

✅ No new issues found.

Reviewed changes — the delta since the prior pullfrog review at 8e43757:

• Read the MIGRATE.md diff through a process substitution. sh/migrate.sh:18 now runs grep -qE '^\+## .+ -> .+' < <(git diff ...) instead of piping git diff into grep -qE, so an early match no longer turns into a SIGPIPE failure under set -o pipefail.

I reproduced the reported bug at this head: on a 589 KB diff that adds the heading, the old pipeline returns 141 (SIGPIPE) while the new form matches and sh/migrate.sh exits 0. shellcheck and the four sh/migrate.test.py cases pass. I also checked the new form for the inverse failure — a failed or empty diff, a binary or gitlink diff, a leading-dash path, and grep status 2 all still flag the file rather than letting it through, so the fix widens acceptance only in the false-rejection case.

Worth noting for the next run rather than as a request here: the test suite's diffs are all below the pipe buffer, so the regression the fix removes has no automated coverage.

quest land watch: the merge queue removed this pull request at 900dd0a because its merge_group build failed (failed_checks).

The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.

The watcher found no failing merge_group job for it before 2026-11-10T18:23:59Z.
