# RPF-WP-0006 - rapp-openbao extraction boundary

## Goal

Prepare the first `rapp-*` extraction by separating the OpenBao workload package
surface from the broader S3 platform ownership in `railiance-platform`.

This workplan follows the first-wave `rapp-*` order defined in
`/home/worsch/railiance-master/docs/rapp-first-wave-candidates.md`.

## Boundaries

This workplan may:

- identify which OpenBao assets belong to a future `rapp-openbao`
- record which OpenBao-related concerns remain platform-owned
- prepare the handoff contract between the future wrapper and S3 platform policy

It must not:

- weaken `railiance-platform` as the owner of secrets custody and policy
- move shared credential lane or approval machinery into the workload wrapper
- require a repo rename or live deployment change before the package boundary is clear

## T01 - Separate package assets from platform-governance assets

```task
id: RPF-WP-0006-T01
status: done
priority: high
state_hub_task_id: "5c0e5411-e47a-5a90-9005-b01762351c0a"
```

Classify the current OpenBao-related files into:

- workload package assets for `rapp-openbao`
- shared platform governance and policy that stays in `railiance-platform`

Done when the distinction is written against real file paths and current usage.

2026-07-25: Added `docs/rapp-openbao-boundary.md` with file-path classification
for OpenBao package assets, split-before-move assets, and retained S3
governance material.

## T02 - Define the first `rapp-openbao` move set

```task
id: RPF-WP-0006-T02
status: done
priority: high
state_hub_task_id: "3e5f8893-d440-5ce5-a436-3f84edad2e7b"
```

Prepare the first move set for the wrapper, including likely candidates such as:

- Helm values and middleware for the OpenBao workload
- UI overlay wrapper assets
- workload-specific deploy/verify scripts
- workload-health and recovery runbooks

Done when the future wrapper has a concrete first file inventory.

2026-07-25: Recorded the first move set in
`docs/rapp-openbao-boundary.md`, centered on Helm values, UI overlay assets,
OpenBao deploy/verify helpers, and the matching `Makefile` targets.

## T03 - Record the retained S3 platform responsibilities

```task
id: RPF-WP-0006-T03
status: done
priority: high
state_hub_task_id: "9a6a2cd9-9306-5721-9652-85f007043c19"
```

Record what must remain in `railiance-platform`, including:

- runtime secret custody as a platform capability
- workload lane policy and approval flows
- cross-workload secret delivery conventions
- platform-wide operator guidance that is not OpenBao-package specific

Done when the wrapper cannot be mistaken for the new S3 ownership home.

2026-07-25: Recorded retained S3 responsibilities in
`docs/rapp-openbao-boundary.md`, including platform-admin policy, workload KV
lane governance, delegated automation, credential grants, and SSH signing.

## T04 - Prepare the repo-creation handoff for `rapp-openbao`

```task
id: RPF-WP-0006-T04
status: done
priority: medium
state_hub_task_id: "a276f76b-48a7-512c-b0f8-786225d88683"
```

Blocked on T01-T03 and the creation of the future `rapp-openbao` repo.

Prepare the minimal handoff needed to create the wrapper repo without breaking
current operators or losing source-of-truth clarity inside `railiance-platform`.

Done when the future package extraction can start from a stable boundary.

2026-07-26: Added `docs/rapp-openbao-compatibility-handoff.md` to define the
current migration-window split: `rapp-openbao` is now the canonical home for
package-owned deploy/overlay/smoke assets, while `railiance-platform` retains
bootstrap, policy, credential-lane governance, and authenticated verification.
`docs/rapp-openbao-boundary.md`, `docs/openbao.md`, and `SCOPE.md` now point to
that split explicitly, so current operators can keep using temporary platform
copies without losing source-of-truth clarity.

## Notes

This workplan is repo-local. The framework-level sequencing stays in
`railiance-master/workplans/RMASTER-WP-0017-rail-rapp-reef-repo-separation.md`.
