That is what invariant I2 forbids, and #457 is the fix: the + * session now REPORTS `TRIAGE-PAYLOAD:` lines, this script validates them + * fail-closed and renders the comment bodies from a trusted skeleton, and a + * separate workflow step posts them. The two comment commands left the + * allowlist (rule 2 — narrowing, the preferred direction) and the PAT left the + * model session's environment entirely. + * + * FAILS CLOSED, unlike its parser sibling. parse-scan-verdict.mjs always exits + * 0 and prints a verdict because its wrapper has a flagged default to fall to. + * This one has no safe default — a comment is either correct or not posted — + * so any defect (unreadable file, is_error, bad anchoring, wrong payload count, + * any schema violation) exits non-zero with EMPTY stdout, and the wrapper runs + * under `set -euo pipefail` with no fallback plus an exit-0-empty-stdout guard + * (the claude-repro.yml publish precedent). Nothing posts when anything is off. + * + * ANCHORING. The payload lines must be the LAST non-empty lines of the last + * result record, one per expected command, AND no other line in that message + * may start with the sentinel. The execution file echoes attacker-controlled + * text, so a loose search is forbidden: an issue body quoting a well-formed + * payload line would otherwise be read as the session's own report. The exact + * count also means a session that finishes the first PR command and bails + * during the second cannot pass on one payload. Whitespace-only lines count as + * lines (jq `select(length > 0)` parity with the check this replaced), so + * trailing spaces after the payloads still fail. Leading narration is + * tolerated — run 29794090279 false-failed an otherwise-correct skip because + * the session prefixed one explanatory line. + * + * THE SANITIZER RUNS ON FIELDS, NEVER ON THE ASSEMBLED BODY. This is the + * deliberate inversion from sanitize-repro-draft.mjs, where the whole draft is + * untrusted and gets one pass. Here the skeleton is trusted and only `title` / + * `reason` are not, so sanitizeField is applied to those two strings BEFORE + * they are interpolated. A well-meant "simplify: sanitize the finished body + * once" refactor would defang the skeleton's own `` + * marker and its `Duplicate of #N` line — both of which + * scripts/auto-close-duplicates.mjs consumes — and silently break auto-close. + * The test sibling pins that coupling against that file's own MARKER and + * DUPLICATE_RE, and asserts a hostile title cannot forge either. + * + * Why sanitizeField is written here rather than imported from + * sanitize-repro-draft.mjs: two of that file's rules are the wrong shape for + * this job. Its mention rule defangs only the three re-trigger handles, but + * these comments are authored by bestaxbot, so ANY `@user` pings a human — + * every `@` is encoded here. Its fence rule is line-start anchored, which + * never fires on a single-line field embedded mid-line. Importing and + * post-tightening would couple this path to a file whose header pins byte + * parity with a different job's sed; the duplication is six short regexes. + * + * CLI contract (the YAML wrapper depends on every clause): + * node scripts/render-triage-comments.mjs \ + * --exec-file= --mode=issue|pr --trigger=opened|labeled \ + * --autoclose=active|off --self= + * - exit 0: one line of compact JSON on stdout — the envelope the publish step + * iterates.
