NK-WP-0056-T12 done: pilot operations; synthetic rotation and revert pass

operations.py: OpenBao KV v2 CAS, LLDAP self-rotation (forward and revert),
ExternalSecret force-sync and status, rollout restart (RolloutFailed is a
definite failure), pilot checks. synthetic_pilot.py on the T08 stack plus
OpenBao 2.5.4 with CCR-2026-0058's policy: rotation completed; a one-off wrong
delivery reverted in declared order with the earlier value restored.

Runner: revert steps run in declared order (BEA-10), definite failures revert,
unknown outcomes stop, receipts carry error types. Found and corrected (in
railiance-platform) CCR-2026-0058's required_parameters refusing reads.
Packaging moved to new T13. 29 executor tests.

+"""Synthetic pilot: the executor rotates the svc-authelia bind on the T08 stack (NK-WP-0056-T12).
+
+Agent-runnable, local Docker only, generated values, everything removed afterwards. Starts the T08 identity
+stack (LLDAP, privacyIDEA, Authelia, KeyCape on the pinned images) and an OpenBao dev server on the platform's
+pinned 2.5.4 image (KV v2 at `platform`, `cas_required` on the bind). The executor gets its own token with
+exactly CCR-2026-0058's policy file plus a journey-read policy, never the root token.
+
+Not on this stack: approval-engine (an in-process carrier with its consume semantics stands in), audit-core
+(an in-memory sink), and Kubernetes. Stand-ins replace the ExternalSecret delivery (re-project the KV value
+into Authelia's configuration) and the rollout (restart the Authelia container). The real Kubernetes adapters
+(operations.KubeDelivery, KubeRestart) are covered by unit tests and exercised live in T06.
+
+Runs:
+  rotation   one admission, the bind rotates; afterwards the old value is refused and the journey passes
+  revert     a second admission whose first delivery projects a wrong value while reporting success:
+             Authelia does not become ready after the restart (definite failure), the executor reverts in
+             declared order, the previous value is back and the journey passes again
+
+Writes a value-free report. Exit 0 when both runs end as expected.

+# NK-WP-0056-T12: the executor rotates a bind on the synthetic stack (2026-10-31)
+
+Agent-run, local Docker, generated values, everything removed afterwards: `uv run bounded-executor/synthetic_pilot.py`.
+
+**Setup:**
+
+- The T08 stack: LLDAP, privacyIDEA, Authelia and KeyCape on the pinned images.
+- An OpenBao dev server on the platform's pinned 2.5.4 image, with KV v2 at `platform` and `cas_required` on the
+  `svc-authelia` bind.
+- The executor gets its own token with CCR-2026-0058's policy file plus a journey-read policy.
+- Stand-ins:
+  - approval-engine: an in-process carrier with its consume semantics;
+  - audit-core: an in-memory sink;
+  - the ExternalSecret: re-projects the KV value into Authelia's configuration;
+  - the rollout: restarts the Authelia container.
+- The Kubernetes adapters are unit-tested against a fake API server (`bounded-executor/tests/test_operations.py`).
+
+Report: [`pilot-report.json`](pilot-report.json). It is value-free: scanned, and the harness asserts that no generated
+value is present.
+
+| Run | Outcome | Evidence |
+| --- | --- | --- |
+| BEA-2026-9001 rotation | `completed` | KV v1→v2; LLDAP refuses the old value and accepts the new; delivery, restart and synthetic journey pass; started event and receipt emitted |
+| BEA-2026-9002 one-off wrong delivery | `reverted` | Authelia never becomes ready after the restart (`RolloutFailed`, a definite failure). Revert in declared order, each step passing its own check: `restore-kv` → `restore-directory` → `redeliver` → `restart-again`. The value from before the run is current again (KV v4); the journey passes |
+
+## Findings that changed the design
+
+1. **CCR-2026-0058's policy refused reads.** OpenBao 2.5.4 applies `required_parameters = ["options"]` to GET as well,
+   so the executor could not read the version it must name for CAS. The executor token got 403 on every read.
+   - Without that line, read and CAS write work.
+   - A stale CAS and a write without `options` are refused, by `cas_required` on the key.
+   - Metadata, delete, sibling reads and new paths are still denied.
+   - The fix is in railiance-platform's renderer and policy file. CCR-2026-0058 needs re-approval.
+2. **Revert order.** Undoing in strict reverse order would restart Authelia before its password was restored. Revert
+   steps now run in the order the admission declares (data, then delivery, then restart), limited to steps that ran.
+   The standard's BEA-10 says so.
+3. **Definite failures revert.** A rollout that never becomes ready was first handled like an unknown outcome
+   (stop, no revert). Operations can now signal a definite failure (`definite_failure`, `executor.StepFailed`),
+   which the runner reverts like a failed check. Truly ambiguous errors still stop.
+4. **Error types in receipts.** Receipts now carry the error *type* of a failed or unknown step, never its message.
+5. **Stand-in artifact:** a restarted container gets a new host port. Fixed in the harness; not relevant to Kubernetes.

+**Done 2026-10-31** ([evidence](../docs/evidence/2026-10-31-nk56-t12-synthetic-pilot/README.md)).
+`bounded-executor/operations.py`:
+
+- the OpenBao KV v2 CAS client;
+- LLDAP self-rotation, the same operation forward and in revert;
+- the Kubernetes ExternalSecret force-sync and status check, and the rollout restart that raises `RolloutFailed`;
+- the pilot checks.
+
+`bounded-executor/synthetic_pilot.py`: rotation `completed`, and a one-off wrong delivery `reverted` in declared order
+with the earlier value restored. 29 tests.
+
+Findings:
+
+- CCR-2026-0058's `required_parameters` refused reads. Corrected in railiance-platform; needs re-approval.
+- Revert steps now run in declared order (BEA-10).
+- Definite failures revert; unknown outcomes stop.
+- Receipts carry error types.
+
+The image part moved to T13 (split agreed 2026-10-31).

+The CLI entry point for one admission:
+
+- reads the admission, the approval id and the configuration;
+- uses Kubernetes auth to OpenBao;
+- uses the in-cluster Kubernetes and audit sender;
+- ships the pinned `lldap_set_password` in the image.

+Also: the Containerfile and the Forgejo image workflow in net-kingdom, and the `rapp-bounded-executor` package
