+## 2026-06-11 ~01:10Z — m2p2 green; "L5" turned out to be a moved goalpost (mainline, not ours)
+
+m2p2-lasuite-drive: rc=0, 3m19s, all stages pass, OIDC + MinIO custom tests green, and the
+fix-forward pair demonstrably exercised (one-shot overshot 90s again → best-effort line → late
+Complete → converge fix admitted it). But results.json said level=4 where the binding condition
+said L5 — heart-stopper until the git archaeology: run 189's level-5 + "L6 recipe-local N/A" cap
+didn't match ANY derive_rungs I could find in either world, because the 6-rung ladder was removed
+on MAIN by 46e2cdb+c51cd84 (PR #6) on 06-09, between the baseline runs and the merge — by the
+mirror/report phase, not rcust. The merge didn't touch level.py (checked 01e6d49^1..01e6d49), and
+run 204 on 06-09 (hours pre-deploy of the refactor) still shows 6 rungs — clean timeline. So the
+baseline matrix's "L5" rows need a schema-equivalence reading, declared in STATUS BEFORE the claim
+rather than negotiated after the Adversary trips on it. Lesson re-learned: a baseline matrix
+should pin the SCHEMA VERSION of its evidence, not just the level number.
