The parity ratchet had quietly failed for 7 skills — v1.58-v1.64 growth landed past the v1.57.7.0 anchors and nothing caught it because this test had no CI lane (verified pre-existing: SKILL.md content is byte-identical to origin/main). Same rebase protocol as v1.53->v1.57.7.0; old baseline retained for the audit trail. Root-caused a second latent bug while rebasing: captureBaseline recorded SKELETON-ONLY bytes while the checker compares UNION bytes (skeleton + carved sections/*.md), so a fresh capture read carved skills at ~2x ratio (ship: 82KB captured vs 183KB checked). captureBaseline now takes sectionedSkills and records unions for carved skills — capture and check measure the same thing, so the NEXT rebase can't hit this. Four CARVE_GUARDS skeleton caps re-ratcheted to current +headroom (plan-ceo 92K, plan-eng 70K, office-hours 100K, design-consultation 70K), annotated inline.
