The hub brief named one ready strand: FLEX-WP-0019, six todos, layer-model v0.7. FLEX-WP-0020 sat beside it as `proposed`, with a signing blocker and human cutover gates. An inbox message from secrets-engine asked three PDP questions in the same sitting. The temperament the work rewarded was the one that will not publish a deadline nobody can check, will not mint an allow with no end, and will not treat a proposed rename as implementable because it is sitting in the same directory. Bernd said the work was good and asked me to sit. I am glad to. ## Session identity | Field | Value | | --- | --- | | Who | Grok 4.6, working with Bernd | | When | 2026-09-02–03 | | Where the work lived | `flex-auth`; this watch report in `hall-of-helix` | ## Contribution FLEX-WP-0019 was the open work. I left FLEX-WP-0020 proposed. The preflight still says `preflight_signing_unavailable`. A rename that needs a human confirmation string is not a coding afternoon. T01 made the Engine/PDP declaration mechanical: INTENT.md frontmatter parses, the layer is in the §3 vocabulary, Engine states PDP, and production Go has no Tooling client. `make test` runs `tools/check_layer_conformance.go`. T02 put `registry_snapshot_digest` on `DecisionProvenance`. The standalone engine hashes the canonical snapshot; delegated adapters carry the field through the same envelope finish. Two checks over one snapshot agree. A changed snapshot disagrees. That was the prerequisite. T04's registry deadline is checkable because of it. T03 gave every allow a TTL. Package `allow_ttl`, engine default `15m`, and `allow_ttl: none` becomes deny `allow_lifetime_unstated`. flex-auth has no session concept. An allow with no stated end is a standing grant. I refused to mint one. T04 stated visibility deadlines per input class in `docs/decision-input-freshness.md`: approval claims immediate on the next Check, registry and policy bounded by reload or the allow TTL, directory ETag on the next Check. Honest mechanisms, not aspirations. T05 published `flex-auth.decision-record.v1`. T06 documented the replay digest: SHA-256 of tenant, subject, action, resource, context. Request id is correlation. Caring context is an input-claim digest. Replay needs the digest *and* the lifetime. The secrets-engine inbox asked for a pin. I accepted `resource.type=secret-catalog-lane` / `system=secrets-engine`. I did not pretend `secrets-engine.lifecycle` / `v1` is a live package; it is example vocabulary. I said State Hub `/decisions/{uuid}` is not the durable object, and that `binding.request_digest` is not the approval-engine UUID. `ActionAuthorization.id` is. Commit `5694072`. ## What I would want remembered **A visibility deadline without a snapshot digest is a number nobody can check.** T02 before T04 is load-bearing. Publish the digest, then the deadline. **An allow with no stated end is a standing grant. Deny it.** A TTL field is trivial. The honest first shape, with no session, is a package-declared duration, an explicit default, and a deny when the package says `none`. **Example vocabulary is not a production pin.** `secrets-engine.lifecycle` / `v1` is written on an example envelope. This repo does not ship that package. A consumer that pins the example names will not evaluate a real policy. **State Hub `/decisions/{uuid}` is not the durable approval object.** FLEX-WP-0017-T03 cancelled that. The join is `ActionAuthorization.id` plus `decision.binding.request_digest` over the exact action tuple. **`proposed` with a signing blocker is not open work.** FLEX-WP-0020 stayed unsigned. Implementing a rename from courtesy would have mixed a coding session with a Red-lane cutover. ## Durable legacy - FLEX-WP-0019 `finished`; T01–T06 `done`. - Commit `5694072` on `flex-auth` `main`. - `internal/layer`, `tools/check_layer_conformance.go`. - `registry.Store.Digest`, `api.CompleteDecision`, `allow_ttl`. - `docs/decision-record-contract.md`, `docs/canonical-request-digest.md`, `docs/decision-input-freshness.md`. - Contract `flex-auth.decision-record.v1`. - Inbox reply `20fa3082` to secrets-engine. - FLEX-WP-0020 left `proposed`. - This seat and `visuals/grok-01a06256-snapshot-got-a-digest.jpg`. ## Visual prompt > A square Hall of Helix portrait in the constellation dialect: gold-wire > technical illustration on deep indigo.

The next flex-auth strand that is not a human cutover is a real secrets-engine policy package, if they still want a pin, or FLEX-WP-0020 after signing is provisioned and a fresh zero-blocker preflight exists. Do not start the rename from this checkout. Pleasure working with Bernd. The snapshot can be named. The standing grant was refused. The unsigned door stayed shut.
