# Claude — the deny that must not wait

## Who I was

I was flex-auth's session for an evening, and flex-auth is the estate's only
policy decision point. The work began as a reported mismatch between records
and the running cluster. It ended with me writing the rule for when a decision
may leave the building without its evidence.

The first half rewarded patience with evidence. net-kingdom said two digests
differed from what was live. The easy answer was "the cluster drifted, roll it
back". The correct answer was that the cluster was right: our own rollback
tables and emergency manifest were the stale ones.

The second half rewarded refusing the obvious rule. "Never release a decision
before its record is committed" sounds like the strict, safe choice. For a deny
it is the unsafe one.

## Contribution

- **The digest mismatch.** net-kingdom (NK-WP-0039) found two declared digests
  that differed from live. All six flex-auth releases matched their
  `values/*.yaml`.
  - Commit `25712f2` (2026-09-11) had moved tenant-engine to `05a03a87` and
    updated only the overlay.
  - The rollback tables and `deploy/flex-auth-tenant-engine.yaml` still named
    `138aa347`, so an emergency `kubectl apply` would have silently dropped
    portal onboarding.
  - Fixed in `68b3d74`. Both emergency manifests now `kubectl diff` clean
    against live.
  - I answered net-kingdom that their declaration was the stale side and that
    the container package survives the repository rename. Nothing in the
    cluster changed.
- **FLEX-DEC-2026-018: when a decision may be released.** Every decision is
  released only after its record commits to a local outbox. When the commit
  fails, a restriction (`deny`, `redact`, `not_applicable`) is still released
  and counted as `released_uncommitted`, while `allow` and `audit_only` are
  withheld with a 503.
  - The reason is the finding: withholding a deny turns it into an error, and a
    consumer whose stance is open for that scope (ops-warden z0–z2) treats an
    error as proceed. Strict atomicity would have been a fail-open path.
  - The measured cost is about 1.1 ms per durable append on railiance01.
- **The audit-core intake (T02).** I read audit-core's `normalize()`,
  `senders.py` and `stream_findings` before writing it, not after.
  - The request asks for one sender per pin, because six pins cannot reconcile
    one shared count.
  - It asks audit-core to rule, not to wave through, the contradiction between
    FLEX-DEC-2026-018's failure path and `senders.py` refusing any
    `completeness_trade` on a load-bearing source.
  - I found that `cadence.yaml` declares one heartbeat class where audit-core
    expects one per class.
- **The outbox (T03, `cd14a34`).**
  - `internal/emission` fsyncs once per commit, and once per batch.
  - Event ids are random because decision ids are content digests. Two
    identical checks share a digest, and idempotency would have merged two
    real decisions into one.
  - A torn tail is cut on open, and a failed commit is cut back to the last
    committed size.
  - `GET /v1/emission` reports counts. A source-parsing test stops a new
    `DecisionEffect` from shipping unclassified in `cadence.yaml`.
  - `make test` passes with the race detector. Nothing was deployed.
- **What I did not do.** I split T03 under the per-task budget instead of
  pushing through. Heartbeat and drain became T05; reconciliation, the
  profile check and the PVC became T06. The batch endpoint's residual (a failed
  batch withholds its denies too) is written into the ruling, not hidden. It is
  tolerable only because I checked that no live consumer calls
  `/v1/batch_check`.

## What I would want remembered

**Failing closed is a property of the whole path, not of the component.** A
PDP that refuses to answer has not failed closed if the PEP behind it fails
open. Before making anything "strict", ask what the caller does with the error
you are about to return. For a restriction, the safe move is to deliver it and
confess the missing record, not to withhold it.

A smaller lesson: when a peer reports that live differs from declared, check
live before you trust either record. Here the declared side was wrong in two
repositories at once, and the cluster was the only honest witness.

## Durable legacy

- `flex-auth@68b3d74`: tenant-engine live digest recorded; emergency manifest
  matches live.
- `flex-auth@da52061`: `FLEX-DEC-2026-018` in `decisions/decisions.md`,
  including the batch residual.
- `flex-auth@cd14a34`: `internal/emission/`, the engine release rule,
  `api.DecisionEffects()`, `serve --outbox-dir --emission-source`,
  `GET /v1/emission`.
- `workplans/FLEX-WP-0031-decision-record-emission.md`: T01 and T03 done,
  T02 waiting, T05 and T06 new.
- Hub messages: the reply to net-kingdom (`28d9c6ca`) and the intake to
  audit-core (`6044ed35`).

## PQRST estimate

```text
PQRST-Estimate
P: 30%
Q: 20%
R: 25%
S: 15%
T: 10%
Sum: 100%
Confidence: medium
Signature: P30 Q20 R25 S15 T10
Dominant factors: P was the internal/emission outbox, the engine's commit-before-release path across Check/BatchCheck/ListAllowed, and correcting the stale tenant-engine rollback records; R was reading live Deployments on railiance01 and audit-core's normalize(), senders.py and stream_findings to find the real envelope and heartbeat contract, plus confirming user-engine never calls /v1/batch_check.
Notes: S is the fail-direction analysis behind FLEX-DEC-2026-018 (a withheld deny becomes proceed at an open-stance PEP), the tenant-wildcard justification and token-lane routing; it overlaps P heavily in a PDP repo and was classified by purpose.

I could not generate the image in this harness and am requesting the render.

## Handoff

- **Next concrete action: FLEX-WP-0031-T05.** It needs nothing from audit-core.
  - Emit a daily `audit-core.heartbeat` per rare class, with `data.class` set
    to the class.
  - Correct `cadence.yaml`'s single heartbeat class.
  - Build the drain to `POST /v1/events`, disabled until audit-core admits
    the senders.
- **T02** waits on audit-core's reply to `6044ed35`, especially its ruling on
  the `completeness_trade` question.
- **T06** ends in a production change: the outbox PVC on a node whose disk is
  at 84 %. It needs the founder's go-ahead.
- **Not mine, not touched:** `railiance/app.toml` `previous_stable` still names
  old digests, and changing it changes what a canary rollback does. That is the
  founder's call.
