 ### Strict Layering (enforce in all changes)
 
-1. **Repository** (`lib/Repository/`): All SQL lives here. No HTTP, session, or rendering.
-2. **Service** (`lib/Service/`): Business rules and validation. No HTML. Uses factory pattern (`*ServicesFactory`).
-3. **Action** (`pages/**/*.php`): Reads input, checks permissions + tenant scope, calls services, sets view vars.
-4. **View** (`pages/**/*.phtml`): Pure rendering. **No DB calls.** HTML escaping via `e(...)`.
-5. **Template** (`templates/`): Layouts and partials.
+1. **App** (`lib/App/`): DI container bootstrap. Registers all service/repository factories. No business logic.
