+- 2026-06-18T07:06Z — **discourse RE-VERIFIED PASS (F-redfix-1 CLOSED).** Builder reworked discourse PR #4
+  @9ff5e19 (force-pushed onto 53ba0910). I inspected the diff: it removes ONLY the orphaned image-less
+  `sidekiq:` block from `compose.smtpauth.yml`; the `app:` service keeps `DISCOURSE_SMTP_PASSWORD_FILE` env
+  + `smtp_password` secret (SMTP auth preserved — sidekiq is internal to the official image). No test

+  `grep -c sidekiq compose*.yml` = 0); (2) my OWN full cold run (`/tmp/adv-discourse-m2v2.log`, RECIPE=
+  discourse @9ff5e19) → **RUN SUMMARY level=5 of 5**, all 5 tiers pass (install/upgrade/backup/restore/

+## REVIEW VERDICT — Gate M2: **PASS** @ 2026-06-18T07:06Z (supersedes the 06:42Z FAIL)
+
+All 6 canon-sweep failures FIXED and independently cold-verified by my own runs / chaos-deploys, one
+recipe at a time, no concurrent load — each two-sided where applicable (M1 failure reproduced first-hand,
+M2 fix proven):
+1. **keycloak** (harness) — WC5 promote at the collision-free `warm-canon-keycloak` domain; live shared
+   `warm-keycloak` SSO UNDISTURBED (app up 4d, service Updated 2026-06-13, /realms/master 200 throughout);
+   all cold tiers pass. Collision-free routing affects ONLY keycloak (sole WARM_DOMAINS member) — zero
+   blast radius on the other 15 canonicals.
+2. **mumble** (harness) — handshake test PASS in 10.3s (load-flake confirmed: fast in isolation); budget
+   widening 60s→180s is pure headroom, asserts unchanged (non-weakening). level=5.
+3. **gitea** (recipe PR #2 @a0f2db8) — chaos-deploy onto retained idle 3.5.3 volumes (genuine pre-fix
+   0-byte app.ini): NO read-only crash (M1 signature gone), app.ini seeded 0→1862B (INSTALL_LOCK=true),
+   `/api/v1/version` 200 {1.24.2}, healthz 200, retained data adopted; canonical UNCHANGED 3.5.3 e6a1cc79
+   (no false promote). Merge-gating honest (published 3.6.0=357926f ≠ fix).
+4. **bluesky-pds** (recipe PR #4 @4987ba9) — chaos-deploy: caddy resolves its OWN app via the FQ swarm
+   name (10.0.5.5 internal) while bare `app` → 10.10.0.12 foreign (the M1 collision); cert obtained, 0
+   connection-refused; external `/xrpc/_health` 200 {0.4.219} (M1 was 000).
+5. **mattermost-lts** (recipe PR #1 @4ca7f418) — cold run all 5 tiers pass incl restore; the M1-failing
+   `test_restore_returns_state` PASSES (pg_backup.sh + restore.post-hook round-trips the dump). level=5.
+6. **discourse** (recipe PR #4 @9ff5e19) — official-image migration; both upgrade-overlay tests pass AND
+   the F-redfix-1 regression (image-less sidekiq in compose.smtpauth.yml) is fixed → level=5, lint R011 ✅.
+
+No standing exceptions. gitea/bluesky end-to-end canonical advance is operator-merge-gated (the fix is
+proven by chaos-deploy; the published tags don't carry it pre-merge) — consistent with the phase's
+"nothing merged" constraint, NOT a shrug. Node left clean: only infra + live warm-keycloak (200); gitea
+idle 3.5.3 canonical unchanged; mattermost/discourse/bluesky no canonical (M1 baseline); no test/warm
+stacks, no run procs; all 6 recipes at their published tags. No open Adversary findings (F-redfix-1
+CLOSED). **No VETO.** The Builder is cleared to write `## DONE` to STATUS-redfix.md.
