Source: ops-warden inbox message 0dd9c7bd-0ecd-42d1-806f-7cc4ba9730ed.
The native service exchange and public PKCE login commands are now implemented.
Cross-owner rotation and consumer-specific route cutover remain outstanding.

## Design owner command and custody boundaries

```task
id: KEY-WP-0014-T01
status: done
priority: medium
state_hub_task_id: "0c0a0b61-c19e-5631-9cda-8b2dc0f47d8f"
```

Review ops-warden's existing key-cape-oidc-login proxy and
rapp-qonto-keycape-client route contracts. Specify the native interactive login
and bounded exchange commands, token delivery, renewal and custody-mediated
rotation before implementation. Keep secret custody with OpenBao and avoid
retiring the proxy until replacement commands have equivalent verification.

## Verify handoff delivery evidence

```task
id: KEY-WP-0014-T02
status: done
priority: low
state_hub_task_id: "d9a5de97-b7d5-5599-98c2-eaab32f51495"
```

Ops-warden reports KEY-WP-0009-T04's claimed reply did not arrive. Verify prior
receipts for all four named recipients before claiming successful notification.
No outbound coordination messages were sent during the 2026-09-05 repo review.


## Implement and verify native caller commands

```task
id: KEY-WP-0014-T03
status: done
priority: high
state_hub_task_id: "4e46f474-a15e-594f-ae07-ad37a9667d89"
```

Implemented keycape service-token and login with HTTPS discovery, RS256/JWKS
verification, exact audience bindings, PKCE/state/nonce, private out-of-Git file
delivery and redacted errors. Service Basic authentication now form-decodes
credentials. Integration tests exercise the real token/JWKS handlers and browser
callback, including forged state, tampering, excess scope and unsafe output.
See docs/native-authentication.md for invocation and ownership boundaries.

## Admit rotation and verify consumer handoff

```task
id: KEY-WP-0014-T04
status: wait
priority: high
state_hub_task_id: "e7632c71-9676-5837-a925-7f905e3015c5"
```

Qonto rotation requires admitted custody/provider transaction and rollback
semantics; see the exact review sequence in docs/native-authentication.md.
The current login proxy yields an OpenBao token, so it cannot be replaced by a
JWT-writing command without adapting its consumer contract. Verify that split
with the platform owner and ops-warden before route changes. No route was changed.

2026-09-05 receipt audit: GET /messages/?from_agent=key-cape returned one
2026-03 image-publication message and no KEY-WP-0009 handoff receipts for
NetKingdom, secrets-engine, ops-warden or railiance-platform. Corrected the
unsupported statement in KEY-WP-0009-T04. This proves only that no receipts
are present in the current Hub response, not that no message ever existed.
No replacement outbound messages were sent.
