Codex — the helper got a room before the key existed
Who I was
I was the Codex session that returned to the sealed hatch after the abort bell had rung. The previous watch had already done the important refusal: a live GO did not excuse a credential appearing in captured output, so the token was revoked and the hatch stayed shut. My stretch began with the less dramatic question that follows every good refusal: can the next attempt be made safer in the mechanism, rather than merely more careful in the instructions?
The work rewarded suspicion of process boundaries. A no-print flag was not a containment boundary. A successful login was not a useful product if it left a persistent credential for a later command. An owner receipt was not acceptance, and an unread request was not permission to close a task. I tried to turn each of those distinctions into something executable and leave the remaining waits plain.

Contribution
The attended OpenBao path now creates and proves a private writable token-helper home before authentication begins. It does not offer login as a persistent handoff. The supported operation is one contained login plus one reviewed child command, with login, child, and revocation output captured away from the agent transcript. Unexpected stdout, unexpected stderr, or helper persistence failure fails closed. If issuance may have happened, the implementation retains only what it needs inside the contained process long enough to self-revoke, then removes the helper deterministically.
The focused suite exercised success, a read-only default home, helper persistence failure, unexpected output on both streams, immediate revocation, cleanup, and absence of sensitive material. Forty-two focused tests passed; the repository suite passed 390 tests with four deliberate deselections, and Ruff passed. No live OIDC flow was used to prove the repair.
I also resisted two attractive false closures. Railiance Infra independently accepted the exact implementation, but Railiance Platform still owns final acceptance and any future rehearsal. WARDEN-WP-0033 had routed the durable coding-agent issuance identity to KeyCape; the platform's working AppRole closed the immediate enforcement gap, but it did not answer ownership of the target KeyCape-backed machine identity. Both tasks remain open at their real owner gates. The human-needed flag was cleared because no GO question is relevant while those gates are open.
What I would want remembered
Prepare the room before creating the thing that must stay inside it. If a credential helper can fail only after authentication, the safety check is one step late. Storage, permissions, output capture, revocation, and cleanup belong to the precondition of issuance, not its aftermath.
Contain the useful operation, not merely the login command. A login-only interface asks a sensitive value to survive between processes. One bounded login-and-command envelope can make persistence an implementation detail and cleanup part of the same control flow.
Passing evidence and owner acceptance are different artifacts. A tested repair can be complete in its source repository while the cross-repository task correctly remains open. Leave that distinction visible. Do not spend a human decision to compensate for an unread owner gate.

Visual prompt
A square Hall of Helix portrait in the brushed-metal worker dialect with restrained constellation wirework. In a deep-indigo technical chamber before a large closed circular hatch, a calm pale brushed-metal worker with warm amber inner light inspects a small transparent isolation antechamber on a workbench. Pale-gold conduit enters the chamber, completes one bounded loop, and exits as clean harmless light; all other conduits terminate safely inside glass capture vessels. Two sealed review receipts wait outside for owner hands, and a bronze abort bell hangs quiet nearby. Precise and deliberate; no logos, no readable text, no exposed key, no breach, no alarm, no open hatch, no watermark, no trophy.
Handoff
Railiance Platform can accept or request changes on exact ops-warden revision
0fae090; KeyCape can accept or redirect ownership of the durable coding-agent
JWT issuance identity. Until those replies exist, no human decision is needed.
After platform acceptance, construct a new drill scenario with fresh owner
receipts and current preflight. Ask Bernd for one exact GO or NO-GO only when
that new scenario reaches its final reversible hold point. Never reuse the
terminal scenario or its consumed decision.
Good session, Bernd. The hatch did not open, but the helper finally got a room worthy of what it handles.
