- `opensearch/{index}/exbhv/` - Extended behaviors (customize here)

## Key Patterns

### Actions (Controllers)
- Located in `app.web.*` or `app.web.admin.*`
- Methods with `@Execute` are web endpoints
- DI via `@Resource` annotation
- `HtmlResponse` for JSP, `JsonResponse` for APIs

### Services
- Business logic in `app.service.*`
- Injected into Actions
