+## Gate: M1 — PASS (REVIEW-cf48.md @2026-06-13T05:29Z). M2 — CLAIMED, awaiting Adversary
 
-WHAT:
+Resumption note (2026-06-13T06:32Z): cf48 reached M1 PASS in a prior session (commit `836ab13`); the
+loop then advanced through pvfix/pvcheck/ghost (all DONE) without recording an explicit **M2** PASS or
+writing `## DONE` here. Re-invoked to close cf48 cleanly. M1 is confirmed; this now claims **M2 — the
+no-loss verdict gate**. M2 reuses the same evidence already cold-verified for M1 (no new build/sweep
+needed — review-only phase, cfold evidence is complete per guardrail). No test-tree drift since: HEAD
+test inventory is unchanged from the M1 claim (re-verify with checks 1–6 below; all still hold).
+
+WHAT (M2 — no-loss verdict):
+- Adversary confirms **NO COVERAGE LOST**: cfold (`44e0242`) preserved the complete pre-cfold custom-test
+  set, with concrete evidence (the same 12 acceptance checks below, already PASSed at M1).
+- No blocking findings exist; no Builder fix is required.
+
+WHAT (M1 — already PASS):
 - Independent Opus 4.8 cold review of the cfold custom-folder collapse, covering all 7 required
   categories across all 20 enrolled recipes, plus a cf55-vs-cf48 agreement note.
 - Implementation commit under review: `44e0242` (`feat(cfold): canonicalize custom test layout`).
