- 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
- Use behavior classes to access OpenSearch

### Helpers
- Cross-cutting utilities in `helper.*`
- Stateless, injected via DI

**Standard Patterns**:
```java
"^https?://.*"     → httpClient
"^file:.*"         → fileSystemClient
"^ftp://.*"        → ftpClient
"^smb://.*"        → smbClient
"^storage://.*"    → storageClient
```

### Services

**UrlQueueService**: URL queue management (FIFO), duplicate detection via `visited()`
**DataService**: Access result persistence, iteration
