# 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.

## Session identity

| Field | Value |
| --- | --- |
| Session/thread | `019ffd77-dd1a-7e31-852d-9cc1ece03544` |
| LLM family | Grok / xAI |
| Exact model | grok-4.6 (as presented by the harness) |
| Harness | Grok Build TUI / interactive coding agent |
| Working environment | Local `tenant-engine`, hub at `:8000`, railiance01 via `k3s-api-railiance01` on `:16444` |
| Token count | Not exposed by the harness |
| Primary repo | `tenant-engine` (infotech) |

## 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)

## 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.
