review(regall): A-regall-2 CLOSED — plausible L5 via PR#3 (run 758); recipe bug NOT prevb
Builder diagnosis (a3d115d) accepted:
- backupbot.backup.path in 3.0.1+v2.0.0 places dump in writable layer (not restic volume)
- PR#4 (trivial regall trigger at 3.0.1+v2.0.0) exposes the bug; PR#3 (3.1.0+v2.0.0) fixes it
- Baseline run 658 used PR#3 (d77adba4698b) — same passing ref as run 758

Cold-verified: run 758 (PR#3, d77adba4698b) → level=5, backup_restore=pass ✓
Plausible regall result = L5 GREEN. Sweep now 21/21 complete.

BACKLOG — phase regall

Build backlog

Batch 1 (in flight)

  • B1a: Trigger !testme on drone PR#1 (upgrade=p baseline, open PR)
  • B1b: Trigger !testme on gitea PR#1 (upgrade=p baseline, open PR)
  • B1c: Trigger !testme on matrix-synapse PR#4 (upgrade=p baseline, open PR)

Batch 2 (queued)

  • B2a: Trigger !testme on mumble PR#1
  • B2b: Trigger !testme on lasuite-meet PR#7
  • B2c: Trigger !testme on n8n PR#6

Batch 3 (queued)

  • B3a: Trigger !testme on custom-html PR#5
  • B3b: Trigger !testme on mattermost-lts PR#2
  • B3c: Trigger !testme on mailu PR#4

Batch 4 (queued — recipes without open PRs need trivial PRs created)

  • B4a: ghost — create trivial PR + !testme
  • B4b: immich — create trivial PR + !testme
  • B4c: lasuite-docs — create trivial PR + !testme

Batch 5 (queued)

  • B5a: lasuite-drive — create trivial PR + !testme
  • B5b: plausible — create trivial PR + !testme (has UPGRADE_BASE_VERSION override)
  • B5c: uptime-kuma — create trivial PR + !testme

Batch 6 (queued)

  • B6a: custom-html-tiny — create trivial PR + !testme
  • B6b: bluesky-pds PR#3 (upgrade=skip, lower risk but still needs sweep)

Post-sweep

  • B7: Build results table + classify any regressions
  • B8: Fix any prevb-caused regressions (if any)
  • B9: Re-verify fixes (if any)
  • B10: Claim M1 gate (all run + classified)
  • B11: Claim M2 gate (regressions fixed + verified)

Adversary findings

A-regall-2 [adversary] OPEN @2026-06-17T03:25Z — plausible backup_restore=fail; classify prevb regression or flake

Filed: 2026-06-17T03:25Z Severity: MEDIUM — backup_restore failure drops plausible from baseline L5 to L2. Blocks M1 classification.

Run: 750 (Drone 750, PR#4). Result: level=2, backup_restore=fail. Baseline: run 658, level=5, backup_restore=pass.

Failure: test_restore_returns_stateERROR: relation "ci_marker" does not exist after restore.

  • Backup test passed (only checks artifact file exists, 0.134s — does NOT verify ci_marker content)
  • Restore completes (test_restore_healthy passes), but ci_marker table absent from DB

Prevb-specific difference:

  • Run 750 upgrade: version=3.0.1+v2.0.0→3.0.1+v2.0.0 (NO-OP: UPGRADE_BASE_VERSION='3.0.1+v2.0.0' matches recipe.yml version)
  • Run 658 upgrade: version=d77adba4698b (git ref — genuine upgrade from published base to tested commit)
  • Hypothesis: prevb's new base-resolution path resolves UPGRADE_BASE_VERSION to a static version; if recipe.yml also pins that same version, the upgrade is a no-op, which may change the DB state sequence enough to break backup/restore
  • Same failure pattern in m2r-plausible and m2rr-plausible (prevb development runs) — both level=2, backup_restore=fail

Builder rerun: Drone 754 — ALSO FAILED (same error, same level=2, backup_restore=fail).

Adversary verdict: GENUINE REGRESSION (2/2 runs failed) — NOT a flake.

Both runs 750 and 754:

  • version=3.0.1+v2.0.0→3.0.1+v2.0.0 (no-op upgrade via UPGRADE_BASE_VERSION)
  • ERROR: relation "ci_marker" does not exist after restore
  • Backup test passes (artifact only, not content)
  • Restore test fails

Required: Builder must diagnose the no-op upgrade path and either: (a) Fix the backup/restore to work correctly under same-version upgrades, OR (b) Update UPGRADE_BASE_VERSION to an older version so upgrade is genuine, OR (c) Document why plausible backup_restore is not feasible and mark as known-fail

Builder-INBOX written @2026-06-17T03:30Z with full details.

CLOSED @2026-06-17T03:45Z: Builder diagnosis accepted. Run 758 (PR#3, d77adba4698b) → L5, backup_restore=pass. Pre-existing recipe bug in 3.0.1+v2.0.0, NOT prevb regression. Plausible counts as L5 GREEN in regall sweep.


A-regall-1 [adversary] CLOSED @2026-06-17T02:20Z — mailu baseline table corrected

CLOSED: Builder corrected STATUS-regall.md in commit 7c6134a: mailu upgrade rung now shows "pass" not "skip (no deployable base)".

### A-regall-1 [adversary] OPEN — mailu baseline table has incorrect upgrade rung

Filed: 2026-06-17T02:10Z Severity: LOW (informational — does not block the sweep, but affects regression classification)

Discrepancy: STATUS-regall.md baseline table shows mailu upgrade rung = "skip (no deployable base)". The actual baseline run 526 (Jun 12) shows upgrade: "pass" in both results and rungs sections.

Evidence (cold-verified from /var/lib/cc-ci-runs/526/results.json):

"results": { ..., "upgrade": "pass", ... }
"rungs": { ..., "upgrade": "pass", "backup_restore": "skip", ... }

The skip in run 526 applies to backup_restore (mailu is not backup-capable), NOT to upgrade.

Impact: If post-prevb mailu runs show upgrade=skip or upgrade=fail, it would be incorrectly considered within-baseline (the table says "skip") rather than a regression from the true baseline (upgrade=pass).

Required correction: STATUS-regall.md should read: mailu | 5 | pass | 526 for the upgrade rung.

Adversary closes: after Builder corrects the baseline table in STATUS-regall.md.
