A blind reviewer rejected this branch on false positives and the repro held up. The gate's intent check deleted every list and blockquote LINE before counting words, then measured what was left against an arbitrary 40. Real people write their story as bullets. Measured on the four realistic-human descriptions from the repro: description before after floor 40 floor 20 own prose written as four bullets 0 55 CLOSE PASS short non-native-English paragraph 38 38 CLOSE PASS specific first-person bug report 34 34 CLOSE PASS mostly a stack trace + a real explanation 28 27 CLOSE PASS The file's own exemption rationale already says a check that is red on every release is a check somebody disables inside a week. Red on every terse-but- genuine contribution dies the same way, and it costs real contributors on the way there — worse than the forgery risks rounds 1-3 chased. - intentWordCount strips the list/quote MARKER and keeps the author's words. Still stripped: fenced code, indented code (new — the other spelling of a fence, guarded so it never eats a list continuation), headings, HTML comments, raw HTML, bare URLs, inline code, link/image syntax, and the template's own bold prompts. An untouched pull_request_template.md still scores 0, pinned against the real file on disk. - INTENT_MIN_WORDS 40 -> 20, documented as a floor against empty/boilerplate- only descriptions, not a quality bar. CONTRIBUTING.md documents no word count at all. Empty, "fixes bug", the unfilled template, 10 words of lorem and an indented log paste all still fail. - The fix-it comment no longer tells contributors to reopen a PR that was never closed — the gate has no close call in it. It now says what actually happens: editing the description re-runs the check (the workflow triggers on `edited`), the PR stays open, a maintainer decides. - sanitizeModelText backslash-escapes `[` and `]`. Escaping HTML killed the <details> forgery, but Markdown needs no angle brackets: an image embed renders a green "APPROVED" picture and a link renders a live phishing target inside a close-lane comment. The file asserted nothing attacker-controlled reaches Markdown unescaped; that is now true. - A label-API failure during a NEUTRAL run no longer throws to exit 2 with no comment. NEUTRAL has no verdict to record, so it logs, still posts, exits 0 — and the comment stops claiming labels were cleared when they were not. The verdict path keeps failing loudly on purpose (ordering note). Four verbatim human descriptions are pinned as PASSING forever. Eight mutations (floor, list markers, quote markers, indented code, markdown escaping, the reopen copy, the NEUTRAL try/catch, the label claim) each fail at least one test. test/pr-gate-workflow.test.ts 145 -> 158 pass, 0 fail. typecheck, actionlint, verify (34/34) green.
