  * Cathedral parity suite — gate-tier (free, structural + content checks).
  *
  * Runs every PARITY_INVARIANTS check against the current SKILL.md output
- * vs the v1.44.1 baseline. Failures get an actionable, per-skill report
+ * vs the v1.53.0.0 baseline. Failures get an actionable, per-skill report
  * showing missing phrases, missing headings, and size ratios.
  *
+ * Baseline rebased v1.44.1 → v1.53.0.0: the brain-aware-planning releases
+ * (v1.49–v1.52) plus the v1.53 redaction guard pushed five planning skills
+ * past the 5% ratchet on the frozen v1.44.1 anchor. Rebasing absorbs that
+ * legitimate growth at HEAD while keeping the per-skill 1.05 ratio so future
+ * bloat is still caught. Historical v1.44.1 / v1.46.0.0 / v1.47.0.0 baselines
+ * are retained in test/fixtures/ for the v1→v2 audit trail.
+ *
  * Periodic-tier LLM-judge parity (paid) lands in Phase B (v2.0.0.0)
  * alongside the sections/ extraction. Plumbing is in parity-harness.ts.
