Skills trial review 2026-10-25 (window end): per-host checklist #474

Checklist for the skills trial window-end review. The trial runs 2026-09-25 to 2026-10-25 (adoption/skills/manifest.json; docs/decisions/2026-09-25-skills-trial-and-usage.md). Owner: the skills-trial owner at that date (the foundation coordinator session, or its successor).

On or after 2026-10-25, for each trial host:

1. Collect usage: python3 tools/skill-usage/skill_usage.py --run-skill-doctor --codex-root <each rollout root>.
2. Tree drift: re-run the retained evidence/artifacts/skills-listing-restore-20260928/tree_drift_check.py with --allow scripts/uv.lock (decision L1066-1074).
3. Apply the prune rule (manifest L30; decision L287-289) per host, counting 30 days from each skill's own install (decision L1143-1154). Compare use counts only within one listing state. The 14 skills whose listing was restored on the workstation become eligible only from 2026-10-28T15:09:02Z (decision L1034-1046). security-audit is not a prune candidate (decision L718-719).
4. Decide semgrep and codeql (decision L1155-1156). The kept verdict winners change only through a sealed re-record (decision L1157-1159).
5. Include the Mac host's receipt from [mac-coordinator] other: skills check, remove verification-before-completion (by 2026-10-25) #472 (decision L1101-1104). Without it, the review covers the workstation only.
6. Write the manifest update and a dated follow-up decision record, then run python3 scripts/validate.py.
