+# DEVX-182: feat(molecule): release lease emission (ships DEVX-181)
+
+- Task: DEVX-182
+- Status: draft
+
+## Problem
+
+DEVX-181 landed on master but was never released: the squash subject
+came out `DEVX-181: ci: retrigger validation` because the branch's last
+commit was an empty `ci:` retrigger. git-cliff found no bump-worthy
+commit, so `v0.55.5` is still latest and the S08 lease producer is
+unshipped. A `feat:` merge is needed to cut the release — and while
+shipping, the emission log line is upgraded from a bare count to the
+actual lease owner and UTC expiry, which is what an operator needs when
+debugging a cleanup race.
+
+## Approach
+
+REQ-1: `start_docker.main()` computes `lease_env()` once and logs
+`owner=` + ISO-8601 `until=` alongside the export confirmation. The
+single call also removes a latent second-boundary inconsistency where
+`emit_github_env` and the count message each re-derived `now`.
+
+REQ-2: Merge squash commit carries `feat(molecule):` so git-cliff cuts
+the next minor release containing DEVX-181's emitter and this change.
+
+## Test Plan
+
+- Update `test_emits_lease_on_success` + `test_prints_and_exports` for
+  the new log format; keep 100 % coverage.
+- `make pre-push` — full devx suite green.
+- Post-merge: verify a `v*` tag > v0.55.5 exists and
+  `pip index versions devx` (Gitea PyPI) lists it.
+
+## Deploy Plan
+
+- Auto-merge; post-merge release job tags + publishes.
+- Infra (OBL-INFRA-658) and GRM (GRM-174) consume the new pin.
+
+## Rollback Plan
+
+- Revert merge; the unreleased module remains dormant regardless.
+
+## Acceptance Criteria
+
+- [x] REQ-1: emission log includes owner and ISO-8601 expiry; lease env
+  computed once — covered by updated unit tests.
+- [x] REQ-2: merge commit uses `feat(molecule):` so the release job
+  cuts a version bump.
