# Architecture register — subsystem status (Completion Program WS1)

**Purpose:** Single **code-backed** snapshot of **Current / Partial / Pilot / Production** for major subsystems. Refresh per milestone or release.  
**Canonical agent matrix:** [`Execution_Matrix.md`](../Execution_Matrix.md) (see [`adr/0002-execution-matrix-canonical-source.md`](adr/0002-execution-matrix-canonical-source.md) for v2 draft status).

## Rules

- Promote a row to **Production** only with tests + runbook + owner sign-off.  
- **Pilot** requires feature flag, scope note, and rollback.  
- **Planned** rows must link to an ADR or workstream ID.

See [`completion-program-workstreams.md`](completion-program-workstreams.md) for the eight workstreams and exit criteria.
