From 97cb8006593f859b90f8da1cd62101fb857e766f Mon Sep 17 00:00:00 2001 From: Edbert Chan Date: Thu, 24 Sep 2026 00:55:33 +0800 Subject: [PATCH 01/17] pr-schema-gate: find the validator in catstack, report UNCHECKED when a repo has none Scope now comes from the .git boundary, not scripts/create-pr.mjs. The validator is scripts/validate-pr-body.mjs, then engine/skills/draft-pr/scripts/validate-pr-body.mjs. A PR-publishing command in a git repo with neither reports UNCHECKED instead of staying silent.

The hook treats exit 0 alongside an UNCHECKED/SKIPPED/not-installed line as a vacuous pass, so the validator gets no credit for a run that never judged the body. The catstack validator prints exactly such a line for a sub-check it skipped -- "Summary reading grade unchecked: Summary has N words; under 30 the score is too noisy to trust" -- while still accepting the body and exiting 0. Every accepted body with a short Summary was therefore reported unchecked. check_body_file now lifts the vacuous reading when the run states its own verdict on the body (VALIDATOR_PASS_VERDICT_RE, "PR body validation passed"). Only a pass verdict counts, so a "failed" banner beside exit 0 stays unchecked. The scan also reads the whole output rather than the first VALIDATOR_OUTPUT_MAX_LINES: truncation shortens what the agent is shown, never what is judged. Two tests in tests/test_advisory.py drive a stub validator with the catstack shape (skip note on stderr, verdict on stdout, exit 0): one asserts the write is silent, one asserts it clears the pending follow-up. Both fail before this change. test_validator_exit_zero_with_an_unchecked_ line_is_not_clean still passes, so the guard against a validator that really did not run is unchanged.

Every existing code-name test uses a changed *file* stem, so deleting the folder loop in changedFileNames kept the whole suite green. Adds the real failing Review Claim as a repro plus its reworded, passing twin. Removing `for (const folder of parts) add(folder, 'changed folder name')` now fails the new test with `0 != 1`.
