Change Management (Stable Interface / Deletion)
Use when
- Changing public APIs across layers (ports, facades, stores).
- Introducing a new pattern or architectural decision.
Workflow
- Define minimal stable interface (MSI): smallest API callers need.
- Prefer additive change; if breaking, include migration notes.
- Add ADR-lite notes (what/why/risks) when boundaries change.
- Verify deletion path: feature can be removed without global entanglement.
