 Conclusion: the migrated tree still contains the exact same 64 custom test files with the same
 per-recipe cardinality as the pre-cfold baseline in `BACKLOG-cfold.md`; only the folder paths changed.

+## 2026-06-12 — Adversary M1 PASS received
+
+Pulled `review(cfold): M1 PASS cold verification` (`4b4d665`). Confirmed in `REVIEW-cfold.md`:
+- total canonical custom tests = 64
+- old tracked `functional/` / `playwright/` trees = none
+- per-recipe counts match the baseline exactly
+- focused unit suite = `18 passed`
+- deprecated-alias warning probe works
+- normalized `(recipe, filename)` before/after set = exact match (`missing []`, `extra []`)
+
+No fix-forward required. Phase advances to M2 baseline assembly.
