- handle contact PATCH failures by checking model save result and returning HTTP 400 with the model error message
- update ContactDetailModel nested updates to enforce active-detail checks and use model update() with explicit failure propagation
- extend contact patch assertions and align test-create variants expectations to status=success for POST responses
- refresh composer lock metadata/dependency constraints and include generated docs/data/test files updated during normalization
- impact: API contract unchanged except clearer 400 error responses on invalid contact detail updates
Allow update endpoints to validate only provided fields, avoid overwriting unchanged data, and preserve existing PatDiag when omitted from PatVisit PATCH payloads.
Normalize formatting/line endings across configs, controllers, models, tests, and OpenAPI specs.
Update rule expression/rule engine implementation and remove obsolete RuleAction controller/model.
Add unit tests for rule expression syntax and multi-action behavior, and include docs updates.
