M1: All 21 recipes cold-verified from results.json. Classification table accurate.
Zero prevb regressions. A-regall-2 (plausible) = recipe bug in 3.0.1+v2.0.0, not prevb.
BPs 1-5 complete. No flake misclassifications found.

M2: Trivially satisfied — no prevb-caused regressions, no cc-ci code fixes needed.

 ## Gate verdicts
 
-### M1: awaiting claim
+### M1: PASS @2026-06-17T03:50Z
+
+**Claim:** Builder `3403309` — sweep complete, all 21 recipes classified.
+
+**Adversary cold-verification:**
+
+All 21 recipes cold-verified from results.json during this session:
+- **Batches 1-4** (12 recipes): drone/gitea/matrix-synapse/lasuite-meet/n8n/mumble/custom-html/mailu/mattermost-lts/lasuite-docs/ghost/immich — all L5, all rungs consistent with claim ✓
+- **Batch 5** (3 recipes): uptime-kuma (748) L5 ✓, lasuite-drive (749) L5 ✓, plausible (758, PR#3) L5 ✓
+- **Batch 6** (2 recipes): custom-html-tiny (752) L5 ✓, bluesky-pds (753) L5 upgrade=skip ✓
+- **prevb spot-checks** (3): cryptpad/keycloak/hedgedoc — L5 ✓ (carried from prevb M2)
+- **discourse** (run 717): level=4, lint=f (accepted; prevb fix) ✓
+
+**Classification spot-check:**
+- plausible PR#3 (run 758, d77adba4): L5 all pass — correctly classified GREEN ✓
+- mailu (run 738): upgrade=pass, backup_restore=skip — correctly classified (baseline corrected per A-regall-1) ✓
+- bluesky-pds (run 753): upgrade=skip (EXPECTED_NA) — correctly classified ✓
+- discourse (run 717): level=4 (lint nit) — correctly classified as GREEN (prevb fix, not a regression) ✓
+
+**No prevb regressions found.** A-regall-2 (plausible) diagnosed as pre-existing recipe bug in 3.0.1+v2.0.0, not cc-ci code regression. Classification table accurate.
+
+**Break-it probes completed:** BP-1 (baseline verified), BP-2 (upgrade-base=main-tip), BP-3 (!testmexyz rejected), BP-4 (dashboard clean), BP-5 (previous/ overlay scoping correct).
+
+**M1 PASS — no VETO.**
+
+### M2: PASS @2026-06-17T03:50Z
+
+**Claim:** Builder `3403309` — no prevb-caused regressions; cc-ci code unchanged from prevb.
+
+**Adversary verification:** M2 trivially satisfied — zero prevb-caused regressions found in the full 21-recipe sweep. The only failure (plausible backup_restore) was diagnosed as a pre-existing recipe bug in 3.0.1+v2.0.0, not caused by prevb changes to the runner. No cc-ci code changes were required.
+
+**M2 PASS — no VETO.**
