# USER-WP-0003 - User Engine Multi-Tenancy

## Goal

Extend the MVP into a tenant-aware service with explicit platform-vs-tenant
boundaries, tenant profiles, tenant memberships, tenant-scoped admin actions,
and tenant isolation tests.

## Tasks

```task
id: USER-WP-0003-T1
status: done
priority: high
state_hub_task_id: "3b6d67cc-be4d-4da3-b08c-f5919c1cb167"
```

Implement tenant identifiers, tenant context resolution, and request validation.

```task
id: USER-WP-0003-T2
status: done
priority: high
state_hub_task_id: "9b8cb25a-eae5-4c6d-abdb-87fa73ba2cc6"
```

Add tenant-scoped account state, profile values, memberships, and persistence
constraints.

```task
id: USER-WP-0003-T3
status: done
priority: high
state_hub_task_id: "a7abd6b0-c35a-4b3a-ae60-1d7db41398f8"
```

Implement tenant admin operations while denying platform-root operations to
tenant admins.

```task
id: USER-WP-0003-T4
status: done
priority: high
state_hub_task_id: "9deb9f46-d214-4311-9b19-7f61d75b4aaa"
```

Extend authorization requests with tenant, target user, membership, assurance,
and scope facts.

```task
id: USER-WP-0003-T5
status: done
priority: medium
state_hub_task_id: "ea8d4127-7ef1-4a7a-80fb-11c8f00c25c3"
```

Add tenant-aware audit records and outbox events.

```task
id: USER-WP-0003-T6
status: done
priority: high
state_hub_task_id: "7d1071a2-c85f-4a21-9842-fcb826c0172d"
```

Add tests for cross-tenant denial, tenant admin allowed actions, tenant admin
platform-root denial, tenant profile precedence, and tenant membership changes.

```task
id: USER-WP-0003-T7
status: done
priority: medium
state_hub_task_id: "6c9e6b82-9a8f-4017-96c3-5df9f3185154"
```

Add tenant onboarding diagnostics for memberships, policy bindings, catalog
scopes, and audit readiness.

## Acceptance Criteria

- Tenant context is explicit on every tenant-scoped operation.
- Tenant data is isolated by constraints and authorization.
- Tenant admins cannot modify platform-root resources.
- Tests cover allowed and denied tenant paths.
