# Design State Hub preflight signing custody

## Prepare the platform design

```task
id: RPF-WP-0034-T01
status: done
priority: high
state_hub_task_id: "bb9e53a9-63b1-5500-8b30-96c5252b8d61"
```

Reviewed owner source and the current platform CCR contract. Delivered
`docs/credential-lane-designs/state-hub-preflight-signing.md` with proposed exact scope, custody, lifecycle, implementation gaps,
approval requirements and positive/negative acceptance evidence. This is a
completed design deliverable, not a live lane or approval. No secrets accessed,
production objects changed or owner messages sent.

## Obtain owner inputs and implement the approved lane

```task
id: RPF-WP-0034-T02
status: cancel
priority: high
state_hub_task_id: "96e4864a-fd17-529b-a72f-69ffd885a962"
```

Confirm exact primary deployment and delivery identity; approve the writer and read CCR; implement dedicated ESO/API-only delivery and a concrete rotation fence. Provision only in an approved window, prove preflight signing without executing a rename, and record API/ESO health and negative access evidence.

Review the linked design and pin current source revisions before implementation.
Do not interpret this workplan or a proposed coordinate as live authorization.

## Portfolio review — 2026-09-05

The design deliverable is complete. The implementation obligation is preserved
in **RPF-WP-0035-T04**, the single credential-lane implementation queue.
T02 is `cancel` here only because it is superseded there; it is not implemented,
waived or externally accepted. The approved design scope and all existing
identifiers remain unchanged. Archived on 2026-09-05 after this consolidation.
