 - Cross-component references in Dependencies and Interactions sections must be kept accurate across all documents. When a component's role changes, update references in all affected documents.

 Each implementation class uses the DbContext internally and works with the POCO entity classes from Commons. Consuming components depend only on Commons (for interfaces and entities) — they never reference this component or EF Core directly. The DI container in the Host wires the implementations to the interfaces.
 
+Site-side exception: read-only SQLite-backed implementations of shared repository interfaces live in `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Repositories/` (currently `SiteExternalSystemRepository`) — same Commons interface, site-local store, writes throw `NotSupportedException` because site artifacts are managed exclusively by deployment from Central.

 `ITemplateEngineRepository` (implemented by `TemplateEngineRepository`) gains CRUD for both native alarm source entities, mirroring the existing alarm-override methods one-for-one:
