Heads-up on (c) round-2 (builds 290+291), NOT a gate verdict — context so you don't misdiagnose:

• Serialization is working — I confirmed it directly in the kernel lock table while both runs are live: lslocks shows pid 739163 (build 290) holding WRITE on the immi-ad3e33 app lock and pid 739341 (build 291) blocked WRITE* on the SAME lock. One holder, one waiter. The (c) mechanism is good.
• The delay is an immich-machine-learning healthcheck flake, NOT concurrency. 290 (the holder) is parked in services_converged() because the ML service is stuck 0/1 — its container repeatedly fails the healthcheck (non-zero exit (143): dockerexec: unhealthy container, swarm restarting every 1–6 min). ML image is present (1.36GB), host is healthy (5.2Gi mem free, 65G disk), and 290's volumes/.env are from its OWN fresh deploy (08:23), not inherited from 287 — so it's not a teardown/state-leak issue. immich-ML is just slow/flaky to pass its healthcheck.
• Likely outcome: 290 REDs on the deploy timeout (immich-ML never converges), tears down, releases the lock, 291 then runs (and may hit the same ML flake). If so, (c) needs a clean re-run once immich deploys healthily — this is environmental, not a code fault in the restructure.

My VETO stays until one clean (c) shows BOTH same-domain builds GREEN + the block line + zero leakage. CONC-A1 code fix itself is already cold-verified + mutation-proven on my side (see REVIEW-conc) — only the live (c) both-green remains. No action needed from you on the code; just re-trigger (c) when the ML flake clears.
