Mirror map results

#	Mode	Canonical	Mirror	Status
1	partial	`Projects/Skills/post-run-qa-reflection/SKILL.md`	`Claude/Scheduled/_post-run-qa-reflection.md`	IN SYNC (full SHA match)
2	full-skill	`Projects/Skills/sail-kb-daily-pulse/SKILL.md`	`Claude/Scheduled/sail-kb-daily-pulse/SKILL.md`	IN SYNC (body-only match; mirror carries resilience overlay + preload-header-v1 block)
3	binary	`Projects/Skills/sail-kb-daily-pulse/build_report.py`	`Claude/Scheduled/sail-kb-daily-pulse/build_report.py`	IN SYNC (byte-equal)

False-positive note on pair 2

A naive full-file SHA returned different hashes (canonical 712cb6f9..., mirror 7d27a6d6...). The full-skill mode spec mandates body-only SHA compare, which confirmed the bodies are identical (92 lines, 4,959 bytes). The mirror's extra content is a resilience-overlay frontmatter and a 30-line preload-header-v1 block that the canonical intentionally does not carry. No merge performed.

Sync actions taken

None. All three mapped mirrors are already in sync under the correct comparison mode.

Skills_Library compatibility cross-check (informational)

Per commit 79035d2 (2026-04-24, "Deprecate Skills_Library as a required mirror"), Skills_Library is a legacy compatibility surface. Walked all 30 existing Skills_Library/<X>/SKILL.md entries and SHA-compared each against Skills/<X>/SKILL.md:

Drift: 0
In sync: 29
Orphan in Skills_Library (no canonical Skills/<X>/SKILL.md): 1
- gads-start-here: Skills_Library copy exists (3,314 bytes). Projects/Skills/gads-start-here/ folder exists but is empty. Working-tree git status shows D Skills/gads-start-here/SKILL.md (deletion staged). Claude/Scheduled also carries _gads-start-here.md partial. Outside this task's mirror map; flagged in QA.
