# USER-WP-0006 - User Engine Implementation Assessment And Polish

## Goal

Assess the implementation against the PRD, architecture blueprint, interface
guidance, and integrated scenarios. Finalize public contracts, documentation,
operability, packaging, and UI handoff readiness.

## Tasks

```task
id: USER-WP-0006-T1
status: done
priority: high
state_hub_task_id: "e0b5621a-4935-45a6-bbd0-41476b3d3317"
```

Review implemented behavior against the PRD, architecture blueprint, and
interface guidance. Record gaps, accepted deviations, and follow-up work.

```task
id: USER-WP-0006-T2
status: done
priority: high
state_hub_task_id: "467eebf2-3a16-45b0-a5bd-28b5c1b634b1"
```

Verify user-engine has not absorbed identity provider, MFA, credential, PDP,
UI, or deployment responsibilities.

```task
id: USER-WP-0006-T3
status: done
priority: medium
state_hub_task_id: "3b7efcaf-041d-4262-973d-6cfd2a011b47"
```

Stabilize endpoint names, error taxonomy, catalog schemas, projection
responses, audit event shapes, and migration contracts.

```task
id: USER-WP-0006-T4
status: done
priority: medium
state_hub_task_id: "a0bc5469-6c6f-429a-a58e-2f6c6489f5c3"
```

Add readiness diagnostics, metrics, structured logs, audit correlation checks,
outbox drain diagnostics, cache status, and runbooks.

```task
id: USER-WP-0006-T5
status: done
priority: medium
state_hub_task_id: "996ffd8d-5006-4393-8214-be8072ebae8e"
```

Finalize developer docs for standalone setup, application onboarding, catalog
authoring, projection consumption, tenant boundaries, and event/audit
integration.

```task
id: USER-WP-0006-T6
status: done
priority: medium
state_hub_task_id: "bc1ca685-be53-4f70-8717-7d7226c81944"
```

Decide versioning, packaging, build artifacts, SBOM/security scan
requirements, migration policy, and compatibility guarantees.

```task
id: USER-WP-0006-T7
status: done
priority: low
state_hub_task_id: "7c4fa8b5-f6c4-434a-85e6-0048449fbdc8"
```

Prepare backend contracts and fixtures needed by future self-service and admin
UI surfaces.

## Acceptance Criteria

- A final assessment records what was implemented, what changed, and what
  remains open.
- Public API, schema, catalog, and projection contracts are coherent.
- Operability and release-readiness checks pass.
- Future UI work has a clear backend contract.
