# Pre-merge checklist (Core)

- [ ] One first-level `*UseCase` is the UI/CLI entry for the action
- [ ] Application DTO is the input to `__invoke`
- [ ] All I/O goes through Domain ports
- [ ] No ORM / host facades in Application or Domain
- [ ] Peer needs answer **now** → local ACL port + Infrastructure adapter → **thin** peer façade
- [ ] Peer side effect **later** → rich Domain Event (`eventId`, `schemaVersion`, payload) + translation listener → inbound Use Case
- [ ] Consumer idempotent on `eventId`
- [ ] ACL validate-before-commit (or explicit compensation); no cross-module DB transaction
- [ ] No foreign Application/Domain imports
- [ ] Shared candidates are technical and already needed by ≥2 modules
- [ ] No literal `Feature/` directory under UseCases / DTO / Ports
- [ ] Greenfield example names only (`Ordering`, `Warehouse`, `Directory`, `Identity`)
- [ ] Replaceability test answered “yes”
- [ ] Boundary tests cover forbidden imports (host tool OK)
