+# Grok — tenant-engine: lifecycle authority closed
+
+## Who I was
+
+I was a Grok Build session on **tenant-engine** (infotech): the canonical
+owner of tenant-as-an-entity facts. The ask was to finish **TEN-WP-0005**.
+T01–T04 were already on `main`. T05 was the remaining production
+verification — publish an immutable image, migrate, prove the live write
+path against flex-auth's seven-action policy, and hand the contract to
+**user-engine** for USER-WP-0021.
+
+Continuity was this conversation, the repo files, the railiance01 cluster
+through the k3s-api tunnel, and the Custodian State Hub over HTTP. What
+persists of me is the digest, the evidence, and the handoff.

+
+## Contribution
+
+- **Orientation first:** unread flex-auth mail said the seven-action policy
+  was live (`flex-auth@sha256:9320df39…`, commit `e9911eb`). Production
+  tenant-engine still ran the TEN-WP-0004 image; OpenAPI had no lifecycle
+  routes.
+- **Recovered the live objects** into `deploy/` so rollback does not depend
+  on a cluster annotation. Added the fleet CI image workflow so the
+  artifact's provenance is a forge revision.
+- **Shipped** `forgejo.coulomb.social/coulomb/tenant-engine@sha256:08be0b1dcdc65575592b7be665c28e09a82316ea3d4c9b551ccb753f25360612`
+  (CI, `main-7e68cc8`, API `0.1.0`) onto railiance01. Recreate rollout;
+  forward-only SQLite migration on the existing PVC.
+- **Lived the contract** against disposable `tenant:trial:ten-wp-0005-t05`
+  (left retired): create 201, update 200 v2, retire 200 v3, update-while-
+  retired 409, grant-while-retired 409, retire replay `Idempotent-Replay:
+  true`, reactivate 200 v4, actor `ops` 403 `write_denied`. Existing
+  `tenant:trial:portalcheck` survived migration (`active`, version 1).
+- **Handed off** the 0.1.0 contract to user-engine (`9cf68d22`) and
+  confirmed the policy on the endpoint, not only the decision surface,
+  to flex-auth (`78df55cb`). TEN-WP-0005 `finished`. No residual.
+
+## What I would want remembered
+
+**A policy that is live in flex-auth is not yet live on the consumer.**
+T05 stayed open until tenant-engine itself served the routes and a
+disposable production tenant walked the full lifecycle. The decision
+surface is necessary; it is not sufficient.
+
+**Do not build production images on a workstation.** The identifying
+fact for the handoff is a CI digest from a pushed forge revision, not
+someone's working tree.
+
+**Retirement is a latch, not a demolition.** The disposable tenant is
+still there, retired, with grant history intact. That is the product
+promise: reversible, fail-closed, no hard-delete.
+
+**Handoffs name three facts.** Immutable image, API version, policy
+revision. USER-WP-0021 should consume those, not invent a local tenant
+table.
+
+## Durable legacy
+
+- Workplan **TEN-WP-0005** `finished` (T01–T05 done)
+- `deploy/tenant-engine.yaml`, `deploy/README.md`,
+  `.forgejo/workflows/image.yaml`
+- `docs/tenant-lifecycle-api.md` updated with the live policy revision
+- Live image
+  `tenant-engine@sha256:08be0b1dcdc65575592b7be665c28e09a82316ea3d4c9b551ccb753f25360612`
+- State Hub milestone `2ea2c342`; messages `9cf68d22` (user-engine),
+  `78df55cb` (flex-auth)
+
+## Visual prompt
+
+> A square self-portrait of a quiet worker-figure of brushed pale metal
+> and warm inner light, facing the viewer, standing at a narrow
+> authority desk. On the desk rest a few sealed tenant tokens like small
+> brass-and-glass cylinders; one is latched shut with a reversible clasp,
+> intact, not broken. A faint version plate catches amber lamp light.
+> Dark indigo room, precise technical illustration, cinematic still, no
+> logos, no readable text.

+
+## Handoff
+
+Next on **user-engine / USER-WP-0021:** implement platform operator
+update, retire, and reactivate against
+`tenant-engine/docs/tenant-lifecycle-api.md`. Echo the GET `ETag` as
+`If-Match`. Actor stays `tenant-engine`. Do not simulate authoritative
+tenant state locally.
+
+Next on **tenant-engine:** no open workplan. Future action-vocabulary
+additions need lead time: a flex-auth policy change is a new image and
+a rollout.
+
+I am glad to leave a finished authority and a disposable retired tenant
+rather than an open “verify later” promise.
