Importance: Low (routine daily sync, zero drift). Status: sync complete; 2 policy items pending. QA: Open.
Daily auto-sync that keeps the canonical, editable skill copies under Projects/Skills/ in lockstep with the partial/full-skill paths the scheduled tasks actually load from Claude/Scheduled/ (plus the Codex fallback preload spec). This prevents the kind of version drift that once left _post-run-qa-reflection.md running at v1.1.0 while canonical was v1.5.0.
Result: every mirror is already in sync. Nothing was written, nothing was committed.
All five mirror-map entries compared byte-equal by SHA256:
_post-run-qa-reflection.md (partial)SKILL.md (full-skill, preload header preserved — no-op)build_report.py (binary)Claude/Scheduled/_skill-preload.md (binary)Codex/_fallback/SKILL-PRELOAD-AND-DRIFT-GUARD.md (binary)Stale-lock janitor: no .git lock files found. Skills_Library cross-check: 1 mirror, matches canonical, 0 drift (60 skills correctly have no legacy mirror). Cross-tool surface check (skill_surface_check.py): clean, zero flags — every skill surface covered or manifest-referenced.
The Claude/Scheduled/ repo has 7 uncommitted items owned by other tasks/agents (3 modified: daily-shipit-cache-clear, drive-dedupe-weekly, sail-kb-daily-pulse/notion_paged_query.py; 4 untracked task folders). None are this task's mirror-map staging targets. This task does not stage/commit/discard them — passive nudge to the owning task that drift is accumulating.
Completed normally. All sync, cross-check, and surface steps ran; deliverable written; Notion export pushed.
discover_unmapped_partials.sh is missing from Skills/skills-scheduled-mirror-sync/ (folder contains only SKILL.md) and exists nowhere under Projects. Step 4 of the skill has silently relied on a script that isn't there. This run used an inline equivalent. Fix options: recreate the script, or update the skill body to formally adopt the inline discovery.skills-scheduled-mirror-sync is an unmapped mirror candidate. Its own canonical Skills/.../SKILL.md exists and the Scheduled deployed copy is referenced by a scheduled task, but it is not in the mirror map. Today the two copies are byte-equal (in sync by luck), but the task's own deployed instructions are not drift-guarded. Recommend adding it to the mirror map in full-skill mode._gads-start-here.md is a referenced partial with no canonical in Skills/ — cannot be mapped (nothing to mirror from). No action unless a canonical is created.
