+## 2026-06-10 — M2(c) PASS round 2 (builds 290+291) + (a) re-run triggered

+- (c) round 2: builds 290 (08:22:30→08:46:05) + 291 (08:22:33→08:49:23) BOTH success.
+  291 log: "== app lock: another run of immi-ad3e33... in flight — waiting ==" at +1s,
+  "acquired" at +1411s = exactly 290's exit. Both: deploy-count = 1 (expect 1), level=4.
+  Slowness was an immich-ML healthcheck flake (Adversary cross-confirmed live via lslocks:
+  one holder pid 739163, one waiter pid 739341 on the same lock inode — serialization observed
+  in the kernel lock table); ML converged inside the 1500s window, both runs green anyway —
+  no clean re-run needed.
+- After both: no harness procs (pgrep run_recipe_c[i] empty), 0 immi/plau services/volumes/
+  secrets/server-envs. Unheld lockfile remains by design (tidy-swept at next janitor probe).
+- (a) re-run on fixed harness: !testme immich#2 comment 14307 @08:50:02Z; will cancel mid-run
+  via drone API once the deploy is in flight, then check pid/lock/leakage + janitor reap.
