Result

No drift. No sync. No commit. All 5 mirror-map files byte-identical between canonical and destination.

What ran

• Stale-lock janitor: no .git lock files in Claude/Scheduled — nothing to quarantine.
• Mirror-map hash compare (5/5 in sync):
  • post-run-qa-reflection.md (partial) — ecf9a73
  • sail-kb-daily-pulse/SKILL.md (full-skill, preload-header verified) — c173c64
  • sail-kb-daily-pulse/build_report.py (binary) — e007f94
  • _skill-preload.md (binary) — 5a5fe1c
  • Codex/_fallback/SKILL-PRELOAD-AND-DRIFT-GUARD.md (binary) — 5a5fe1c
• Commit/push: correctly skipped (no sync). Claude/Scheduled on main @ 4f281b9.
• Skills_Library cross-check: 1 skill (post-run-qa-reflection), MATCH vs canonical.
• Cross-tool surface check: clean, no flags. All loader/MCP/API surfaces covered.

Working-tree heads-up (read-only)

Claude/Scheduled has 7 dirty/untracked entries owned by OTHER tasks (daily-shipit-cache-clear, drive-dedupe-weekly, sail-kb-daily-pulse/notion_paged_query.py, plus 4 new untracked task dirs). None are mirror-map files. This task did not touch them.

Pending items (mirrored to Codex QA queue — Notion is storage only)

1. Add skills-scheduled-mirror-sync/SKILL.md to the mirror map (full-skill mode). It is the task's own prompt; today it is byte-identical (a6399f8) so no live drift, but mapping it prevents this task from silently running stale. Recommended next edit pass.
2. Recreate missing discover_unmapped_partials.sh. Not present in the skill folder; Step 4 ran via a manual lightweight scan this run. Recommended restore so discovery is automated.

QA

Status: Open (pending policy/improvement items above; no drift). Tag set: skills-sync, drift-prevention, daily, QA: Open.

Pickup for next session

Run is idempotent and clean. Next agent only needs to act if R1/R2 are approved: add the map entry and/or restore the discover script, then re-run. Full run log: Codex/skills-scheduled-mirror-sync/2026-06-09.md.
