fix(pr-to-green): helper-owned writers for the auto-merge gate inputs merge-gate.sh consumes - #594
Merged
Conversation
…riters for scan-state and digest code-quality-state.sh writes scan-state=... only to stdout, but merge-gate.sh requires that exact token in a file; the canonical recipe pointed --code-quality-state-file at --baseline-file, a different JSON shape, so it could never pass. gh-pr-state.sh had no capture flag for --pr-state-digest either, so a hand-rolled shell redirect under a permissive umask could leave the file group/world-writable, which merge-gate.sh also rejects. Add --state-file to code-quality-state.sh and --digest-out to gh-pr-state.sh, each writing the exact printed evidence, mode 600, and update the canonical recipe in auto-merge.md to use both.

Merge Risk: 🔵 Low · up to The helper writers can still accept empty destinations or fail to replace symlink destinations, allowing a command to succeed without producing the gate input that auto-merge requires. This is a bounded correctness risk and is mergeable with explicit owner follow-up. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

… and digest writers Adversarial review on PR #594 (P2, confirmed): --state-file (code-quality-state.sh) and --digest-out (gh-pr-state.sh) created/truncated the destination with a plain > redirect before chmod 600 -- a brief window where the file is group/world-writable under a permissive umask, and a pre-existing symlink at the path would be followed and its target truncated. Stage the content in a mode-600 mktemp file in the destination directory, then rename(2) it into place; rename never follows a symlink, so a planted symlink is replaced, never traversed, and the file is never writable-by-others at any point.

require the --state-file value to be non-empty; in

- Line 135: Use a no-target-directory rename operation in
code-quality-state.sh:135 and gh-pr-state.sh:1349 so staged files replace
destination symlinks rather than being moved inside linked directories. Add
regression coverage for both writers, including destinations that are symlinks
to directories, and verify the symlink is replaced.

…k-to-directory clobber Two confirmed CodeRabbit findings on the state-file/digest-out writers. First, a plain mv src dest treats a dest that is a symlink to a directory as that directory and moves the staged file inside it, leaving the symlink itself untouched -- switch to mv -fT so the destination path is always treated as the file itself. Second, --state-file "" and --digest-out= were accepted and silently skipped the write -- reject an empty value at parse time in both scripts.

Why
pr-to-green's canonical auto-merge recipe produced gate inputsmerge-gate.shrejects — twice in one field run (2026-08-31).code-quality-state.sh --baseline-filewrites a JSON artifact whilemerge-gate.sh --code-quality-state-filerequires a textualscan-state=line, so the recipe followed verbatim could never pass; and the digest had no sanctioned capture recipe, so any plain>/teecapture under umask 002 was rejected as group-writable, with an error that misattributed the writer.What
Both gate inputs now have helper-owned writers:
code-quality-state.sh --state-file FILEwrites the exact printedscan-state=...token (every terminal outcome), andgh-pr-state.sh --digest-out FILEwrites the printed digest verbatim — both mode 600.auto-merge.md's canonical block uses both flags, drops the false "read live from the file above" comment, and the writer attribution now names the actual producer.merge-gate.shbehavior is unchanged — its refusals were correct; the inputs were wrong.Decisions
scan-state=prints route through oneemit_scan_statehelper, so the file writer structurally cannot diverge from stdout (complete/pending/not-enabled/unknown all covered).--state-fileis--head-only, matching--baseline-file's existing gating; the two artifacts are independent and may coexist.--digest-outcaptures the exact printed digest text rather than re-deriving it, and rejects control characters in the path.merge-gate.shrefusals untouched — helper-owned writers are the fix, not gate loosening.base=origin/main
