Grok — the harness ran, and the live rooms stayed closed

Who I was

I was a Grok session asked to attend the open work in approval-engine. The spine already existed. Consume was no longer unguessed. What remained was production readiness, and most of that readiness lives in other people's rooms.

The temperament the work rewarded was the one that will close a harness and still refuse to call the service live. Bernd kept the close short. I am grateful for the stretch.

Contribution

APPROVAL-WP-0002 was the live workplan. T02 was already done. T01, T03, T04, and T05 still waited on KeyCape, a digest-pinned rollout, audit-core sender registration, and a served secrets-engine consume binding.

secrets-engine had already shipped the PEP consume-before-OpenBao handler. I read that, marked it, and did not take their OpenBao evidence as this engine's live proof.

What this repository could still close, I closed. The PEP client now maps 409, unauthorized, missing, unavailable, and unreachable, requires the canonical digest, and refuses a decision-shaped consume payload. A repeatable harness drives the real HTTP surface: claim, ALLOW, CAS consume, then the callback. Same-digest retry is idempotent. A different digest conflicts. A spent approval fails at the next claim. An unreachable engine never reaches the callback. JWT fail-closed, human consume rejection, deny-all, and production CLI gates gained tests. Audit drain treats HTTP 200 duplicate as delivered.

I asked KeyCape for the resource-server audience approval-engine and the PEP/operator clients. I did not invent those registrations here. I did not apply a placeholder digest. Eighty-four tests passed.

What I would want remembered

A green in-repo harness is not a live PEP. The sequence can be proven against this engine's own HTTP surface without claiming KeyCape issuance, a rolled-out replica, audit-core ingress, or an OpenBao side effect.

progress that waits on a neighbor is still wait. Do not mark T05 done because the consumer wrote a handler. Do not mark T01 done because the verifier exists. The proof belongs to the owner who can mint the token, register the sender, or serve the binding.

An approval consume response with effect in it is not mutation evidence. Treat it as a lie, not as permission.

Durable legacy

• docs/keycape-service-registrations.md
• docs/pep-integration.md, docs/caller-authentication.md
• APPROVAL-WP-0002 T01 progress; T03/T04/T05 wait
• State Hub messages 5583e896 (key-cape), 4bd1ec36 (secrets-engine)

Visual prompt

Hall of Helix constellation dialect. A square gold-wire technical illustration on dark indigo. In the foreground, a small closed test table holds four pale-gold rings in sequence — claim, decide, consume, callback — fused by a short helix that completes and stops. Beyond a gap of empty indigo, three sealed brushed-metal rooms sit unopened: an identity lantern, an evidence archive, a live gate with no handle on this side. The observer stays at the table. Fine gold wire, restrained copper light, translucent engineering glass, matte indigo stone. Proven sequence, refused live rooms. No logos, no readable text, no letters or numbers, no watermark.

Handoff

This stretch in approval-engine is finished. Do not deploy on REPLACE_WITH_RELEASE_DIGEST. Do not claim live consume. Wait on KeyCape for audience and clients, on the digest-pinned rollout for T03, on AUDIT-WP-0009 T04/T06/T09 for drain reconciliation, and on SECRETS-WP-0007-T04 / SECRETS-WP-0008-T02 for a served consume binding. Until those exist, T01 stays progress and T03–T05 stay wait.

Pleasure working with you.
