review(rcust): be2026a fix-forward CLEARED (all 3 conditions met, independently verified) + ACCEPT L5≡L4+OIDC-pass equivalence — lasuite-* L5 baselines stale (c51cd84 4-rung predates rcust, git-proven), rcust innocent, OIDC coverage preserved. Consumed 01:10Z inbox. M2 still open: bluesky upstream-breakage note, drone-path runs, zero-leak, my sample re-check

+### be2026a conditions CLEARED + SSO-baseline staleness finding (independent) @2026-06-11T01:12Z
+
+Reached the conclusions below COLD (own git archaeology + run-dir jq) BEFORE reading the Builder's
+01:10Z inbox — which then concurred. Anti-anchoring preserved (no JOURNAL read; inbox read after my
+own derivation).
+
+**be2026a fix-forward — ALL 3 CONDITIONS SATISFIED → fix-forward FULLY CLEARED:**
+1. **Post-fix lasuite-drive (m2p2, merged main 6cabbe7, ffa7d585afa2, PR=1): L4, rc=0, 3m19s.**
+   Independently verified: flags clean_teardown=true + no_secret_leak=true; all 4 essential rungs
+   pass; `test_minio_storage::...object_roundtrip` PASSED; `test_oidc_..._keycloak` PASSED. The
+   install converge no longer hangs — both fix-forwards (1357544 best-effort poll + 6cabbe7
+   completed-one-shot converge) exercised in one run. The literal "L5" in my condition is
+   **unmeetable on current code and NOT an rcust effect** — see staleness finding below; I accept
+   the L4-equivalence. Fix works end-to-end.
+2. **Merged diff == branch diff** — verified earlier (4428e76): lifecycle.py + test file
+   byte-identical to be2026a.
+3. **discourse A/B — restructure-NEUTRAL.** m2p-discourse (NEW main, 7ae7b0f, PR=2) = L1 and
+   ab-discourse-7ae7b0f-oldmain (OLD main, SAME ref, SAME PR=2) = L1, SAME stage (upgrade), SAME
+   message (`eb96de94+U` HC1 re-checkout). old==new byte-identical → rcust did NOT regress discourse.
+   The L4(184)→L1 vs baseline is pre-existing env drift since 06-05 (filed below), not rcust.
+
+**FINDING [adversary] — M2 baseline matrix has 3 STALE L5 entries (lasuite-docs/drive/meet).**
+Independently established: the level ladder dropped 6-rung(L5)→4-rung(max L4, integration &
+recipe-local now OPTIONAL/non-laddered) in mainline PR#6 (c51cd84 "4-rung ladder", + 46e2cdb),
+which `git merge-base --is-ancestor c51cd84 01e6d49^` confirms is an ANCESTOR OF PRE-RCUST MAIN.
+The rcust merge touches level.py NOT AT ALL and results.py by +4 cosmetic P5 lines; compute_level
++ derive_rungs are byte-identical old-main↔merged-main. So NO current-code run (rcust or pre-rcust)
+can produce L5; baselines 188/189/204 (L5, integration:pass) were recorded under the OLD schema
+(run 204 ran 06-09 hours before the refactor deployed). **rcust is INNOCENT of L4≠L5.** Integration
+coverage is NOT lost: the requires_deps OIDC tests EXECUTE and PASS (skip-count 0) on current code —
+verified in m2p2 AND the sweep's m2r-lasuite-docs (`test_oidc_login_via_keycloak` +
+`test_oidc_password_grant_...` PASSED) and m2r-lasuite-meet (`...password_grant...` PASSED).
+ACCEPTED equivalence for the M2 matrix: **old L5 ≡ new L4 (all 4 essential rungs pass) + requires_deps
+OIDC test PASSED (skip-count 0)**. Under this, lasuite-docs (m2r L4) / lasuite-meet (m2r L4) /
+lasuite-drive (m2p2 L4) all MATCH. (Note: this validates — but corrects the basis of — the Builder's
+first-sweep "lasuite-docs/meet matched baseline"; they are L4+OIDC, not numeric L5.) This is a
+matrix-staleness correction, NOT a rcust regression; no VETO.
+
+**Still OPEN for the M2 verdict (my side):** (a) per-recipe levels reconciled vs the CORRECTED
+baseline for all 21; (b) bluesky-pds is L0 on BOTH old & new main (upstream image
+`Cannot find module index.js`) — restructure-neutral but also cannot match its L4-equiv baseline on
+ANY current run → needs a DECISIONS/DEFERRED note as non-rcust upstream breakage, not a silent
+mismatch; (c) the 2 drone-path !testme runs (immich#2/plausible#3); (d) zero-leak teardown sweep;
+(e) my own independent re-check of ≥5 recipes' logs + ALL mismatches before any M2 PASS.
