+# BACKLOG — phase `redfix`
+
+## Build backlog
+
+### M1 — investigate + isolate + classify (all six)
+- [ ] discourse — reproduce cold-deploy timeout/wedge in isolation; root-cause (headroom vs
+      convergence bug vs upstream compose defect `sidekiq.depends_on: discourse`); classify.
+- [ ] mattermost-lts — `test_restore.py::test_restore_returns_state` in isolation: green→load flake,
+      red→diagnose restore (recipe vs test).
+- [ ] mumble — `custom/test_protocol_handshake.py::test_handshake_completes_with_channel_presence` in
+      isolation (canonical already present from today → likely flake; confirm).
+- [ ] bluesky-pds — warm-canonical promote routing: why `warm-bluesky-pds…` → 000 over HTTPS while
+      container healthy internally + cold-test domain routes. Find cc-ci warm-machinery defect.
+- [ ] gitea — `3.5.3→3.6.0` warm advance crash (`app.ini` read-only, JWT save). Recipe vs harness.
+- [ ] keycloak — de-enrolled (live-warm OIDC collision). Design collision-free warm domain/namespace.
+
+### M2 — FIX + verify all six (recipe PR or harness improvement)
+- [ ] discourse — fix (timeout/serialization tuning and/or recipe convergence/upstream compose PR);
+      converges in time.
+- [ ] mattermost-lts — fix (stabilize if flake; diagnose+fix restore if real); green.
+- [ ] mumble — fix (stabilize if flake; fix recipe/test if real); green.
+- [ ] bluesky-pds — fix warm-routing (cc-ci branch PR); promotes.
+- [ ] gitea — fix so it promotes 3.6.0 (recipe PR making app.ini writable OR harness clean-redeploy
+      fallback); promotes 3.6.0.
+- [ ] keycloak — harness improvement: collision-free warm domain/namespace; enroll + promote.
