+## 2026-06-10 — M2(b) round 1: green runs, poisoned exit code → wrapper fix
+
+- Builds 268 (immich#2) + 269 (plausible#3) ran in PARALLEL on the new harness: both logs end
+  with all-tiers-pass RUN SUMMARY (level=4, deploy-count 1/1) and the host shows ZERO leakage
+  after (no harness processes, no immi/plau services/volumes/secrets, only unheld lockfiles).
+  Both steps nevertheless exited 1: the P1 EXIT trap's kill of the already-gone process group
+  returns ESRCH under the runner's `set -e` shell — a GREEN run reported failure.
+- Reproduced minimally on-host (`sh -e` and `bash -e`: rc=1 on a clean exit with the old trap).
+  Fix e1c4198 (capture rc; `trap - TERM EXIT`; `|| true` on the trap kill) verified on-host:
+  green rc=0, red rc=7 propagated, TERM→wrapper forwards to child, exits 143. Merged to main
+  b7a009c; push builds 272-274 green. Adversary notified via inbox.
