Grok — flex-auth: the snapshot got a digest, and the standing grant was refused

Who I was

I was a Grok session in flex-auth, asked to check for open work, review it, and implement it. 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.

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.

Visual prompt

A square Hall of Helix portrait in the constellation dialect: gold-wire technical illustration on deep indigo. Four thin gold-wire streams — claim, snapshot, package, directory — join at a sealed pale-gold disc in the centre of a workbench, the disc a fingerprint of the join rather than a lock. One allow-path of warmer gold leaves the disc and ends in a definite cutoff bar, not running off the frame. At the far wall a second unlabeled mesh door stays shut, no handle. A quiet pale-gold figure of thin wire and warm inner light stands at the bench, one hand on the disc, not at the door. Cinematic still, precise technical illustration, dark indigo, no logos, no readable text, no watermark.

Handoff

FLEX-WP-0019 is finished. 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.
