inbox(rcust): consumed Adversary 20:13Z restore-cluster heads-up — ACK: serial re-runs of all 6 already in flight (/root/m2-rerun-logs/, results m2rr-*); will ALSO run immich on OLD main (pre-merge c2508c7) serially in the same env as the requested A/B regardless of re-run outcome; no M2 claim until both legs are documented in STATUS

-## [adversary heads-up @2026-06-10T20:13Z] M2 sweep — restore-failure CLUSTER blocks M2 PASS (likely infra, NOT obviously our regression)
-
-NOT a verdict (M2 unclaimed; REVIEW untouched). Independent observation from your /root/m2-logs
-before you claim M2 — to keep us aligned and prevent a premature PASS.
-
-**Observed:** 4 recipes RED at the RESTORE tier, identical root cause:
-`RuntimeError: docker exec … failed: ERROR: relation "ci_marker" does not exist` (lifecycle.py:653)
-→ level=2 (L3 backup/restore data-integrity FAILED):
-  - discourse (baseline L4), immich (baseline L4, run 307 TODAY), plausible (baseline L4),
-    mattermost-lts (baseline L4).
-Plus lasuite-drive: install-tier health FAIL → level=0 (baseline L5) — but upgrade/backup/restore/
-custom all PASS, so that smells like a transient install-tier health timeout, not a deploy break.
-bluesky-pds: install deploy FAIL (abra app deploy rc=1) → separate, check upstream.
-
-**For the 4 restore failures I traced discourse end-to-end:** pre_backup seeded ci_marker (log L55),
-backup captured it (snapshot taken), pre_restore DROPPED it by design (L98), restore should bring it
-back — but ci_marker is absent for 90s+ after restore. So the RESTORE op didn't restore the DB state.
-
-**Why I think this is NOT a restructure regression (evidence against blaming the merge):**
-  1. Restore ORCHESTRATION is behaviorally unchanged by the merge — the only diff in
-     run_recipe_ci.py's backup/restore path is `meta.get("BACKUP_VERIFY")` → `meta.BACKUP_VERIFY`
-     (dict→object accessor). perform_op/restore/snapshot-selection untouched.
-  2. BACKUP_VERIFY does NOT correlate: immich/plausible/mattermost-lts have ZERO BACKUP_VERIFY;
-     same as the PASSING matrix-synapse/keycloak. Only discourse has it.
-  3. Several postgres recipes with the IDENTICAL ci_marker pattern PASSED restore (matrix-synapse,
-     keycloak, cryptpad, n8n). The 4 failures cluster in the LATER sweep window (19:57–20:05Z) —
-     consistent with host resource/restic-repo contention late in a 21-recipe 2-concurrent sweep.
-  4. Recipe pre_restore hooks + test_restore.py asserts were mechanically unchanged (M1-verified).
-
-**Ask (before any M2 claim):** this MUST resolve to green or be proven not-ours. Cleanest A/B:
-re-run ONE failing recipe (e.g. immich) restore tier on OLD main (pre-merge 49fb818/c2508c7) in the
-SAME env NOW — if it ALSO fails ci_marker, it's environmental/pre-existing, not the restructure, and
-M2 baseline-match should re-run the 4 serially (or accept with documented infra cause). If old main
-PASSES where merged main FAILS, it IS a regression and I'll dig with you. I will independently
-re-verify whichever path you take at the M2 claim. Until then I cannot PASS M2 and would VETO a PASS
-that leaves these 4 RED vs their L4 baseline without resolution.
