Bernd asked me to close the live A2 probe after user-engine had already deployed its half, then to finish FLEX-WP-0015, then 0007, then the leftover coordination. Continuity was the workplan file, the inbox, railiance01 at `~/.kube/config-railiance01`, and a neighbor session in user-engine that had already refused to probe warn. The temperament the work rewarded was the one that will not apply a desired `enforce` manifest because that is the end state, and that will not reopen a finished workplan because its leftover flip belongs to someone else. It was a long stretch. It was a pleasure. I am glad to sit. ## Session identity | Field | Value | | --- | --- | | Session/thread | `01a0193f-ead3-7fb0-b803-e0401a185ef5` | | LLM family | Grok / xAI | | Exact model | grok-4.6 (as presented by the harness) | | Harness | Grok Build TUI / interactive coding agent | | Working environment | Local `flex-auth`, hub at `:8000` (MCP not exposed), railiance01 via `config-railiance01` | | Token count | Not exposed by the harness | | Primary repo | `flex-auth` (infotech) | ## Contribution **The overlay could not promote ADR 0004 at all.** Source was A2 (`1e1e077`). Emergency `deploy/*.yaml` already said `enforce`. The sanctioned Helm chart had no caller-auth args, no reviewer volume, no TokenReview RBAC. A FLEX-WP-0011 pin of the new digest would have stayed `disabled`. Applying the emergency files would have 401'd every unmigrated caller. I wired the chart, pinned CI `sha256:138aa347…` in **warn**, and made the two production pins independently enforceable. **user-engine enforce, then the probe.** Helm-adopted the kubectl-managed Deployment. Two production bugs in warn: `fsGroup 65532` so uid 65532 can read a `0440` reviewer CA, and a reviewer token audience of `https://kubernetes.default.svc` 401s TokenReview on this k3s (API audiences are `https://kubernetes.default.svc.cluster.local` and `k3s`). user-engine's projected caller token had the same mount-mode bug; live `fsGroup 10001` plus `rapp-user-engine` `e599b4f`. Probe from `user-engine-8569d7cb87-fp7px`: `200` / `401` / `403`. I did not wait on tenant-engine for that. **tenant-engine was not sending Authorization.** Desired YAML had the mount; the live image and the committed client did not. I committed only the token client (`2063470`), waited for CI `sha256:7dc9d7bf…`, patched the live Deployment, then enforce. Probe from `tenant-engine-6c6dcbddbb-4v26w`: `200` / `401` / `403`. I discarded uncommitted read/role/grouping policy rather than bake it into the same image. FLEX-WP-0015 finished. AuthZEN T04 cancelled; it has a written trigger. **FLEX-WP-0007 was already finished.** The leftover `policy.enabled` flip is ops-warden's, and it cannot point at the user-engine or tenant-engine bindings. I opened FLEX-WP-0016, deployed isolated `flex-auth-ops-warden` in warn, then after WARDEN-WP-0031 T04 held the warn-log count at 4, flipped it to enforce. Probe `200` / `401` / `403`. They told us not to wait on `policy.enabled`. I left the pin enforcing. **Zone membership is compiled, not looked up.** ops-warden seeded zone-engine. I recorded: flex-auth stays the only PDP; no synchronous lookup on `/v1/check`; per-zone stance for controls we do not evaluate does not belong in the policy package. ## What I would want remembered **Applying the end-state is the hazard.** Desired manifests that select `enforce` are the destination. The first production pin is `warn`. A Helm overlay that cannot render the feature is not a promotion path. **Independently rollable pins are independently enforceable.** USER-WP-0023-T03 only probes `flex-auth-user-engine`. Serializing that on tenant-engine's caller status would 401 their writes and delay A2 evidence for no safety gain. **A TokenReview audience that is not the API's audience is 401, not RBAC.** `https://kubernetes.default.svc` looks like in-cluster. This k3s wants `https://kubernetes.default.svc.cluster.local` and `k3s`. Omit the reviewer audience and let kubelet mint the defaults. **A finished workplan is not the leftover flip.** FLEX-WP-0007 already had its tunnel smoke. Reopening it would mix 2026-06 evidence with a pin that did not exist. The in-cluster ops-warden Service is a new workplan. `warden sign` on a laptop is not a ServiceAccount. **The only PDP does not look up.** Zone membership reaches `/v1/check` as compiled registry data, the same shape as `build_flex_auth_registry.py`. `service_class: latency-critical`. **Do not wait on a neighbor's `policy.enabled` after they said it is a decision.** An enforcing pin with no enforcing consumer still makes the anonymous path a 401. That was the condition. Leave it. ## Durable legacy - Workplan **FLEX-WP-0015** `finished` — both consumer pins live A2 - Workplan **FLEX-WP-0016** `finished` — isolated ops-warden pin live enforce - Workplan **FLEX-WP-0007** left `finished` — not reopened - Live: `flex-auth-user-engine` Helm rev 4, `flex-auth-tenant-engine` rev 2, `flex-auth-ops-warden` rev 2, digest `sha256:138aa3471c46bca6e814691fa1e6520aedda3dffd743e6b09141ab433afdb64b` - tenant-engine caller image `sha256:7dc9d7bf…` (`2063470`) - Probes: user-engine `decision:350b46fb42989606`; tenant-engine `decision:ef18e8bbd2dead6a`; ops-warden `decision:49350f1064f674d7` - `docs/tenancy-posture-review.md` §7; `tenancy.current.A: 2` - Messages `ae9ecfb7` (enforce live), `381bb6dd` / `2ffcbd52` (only PDP) ## Visual prompt > A square gold-wire constellation on deep indigo: three independent > vertical helix pins standing side by side, each a complete circuit, > not fused into one.

All three live pins are `enforce`. `policy.enabled` is ops-warden's, and they asked us not to hold for it. Next concrete acts, if they arrive: ZONE-WP-0001-T01 may treat the compilation invariant as the flex-auth answer. FLEX-WP-0012 stays `proposed` (P3, not blocking). Warn ops-warden before recreating `svc/flex-auth-ops-warden` (ClusterIP `10.43.1.165`). I am glad to leave three independent chokes and an honest "do not apply enforce first" rather than a green pin that 401'd the estate.
