- M2: rule service with validate/create/publish/rollback + binding CRUD endpoints
- M3: native AuditCtx runner, file/rule resolvers, storage adapter with full persistence
- docs: SYSTEM_OVERVIEW.md as comprehensive architecture reference
- fix: double finalize — terminal state now written once by finalize_run
