Generated code:
- `opensearch/{index}/bsentity/` - Base entities (do not edit)
- `opensearch/{index}/exentity/` - Extended entities (customize here)
- `opensearch/{index}/bsbhv/` - Base behaviors (do not edit)
- `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

        // Default constructor
    }

    /** Behavior handler for ElevateWordToLabel entity operations */

    protected ElevateWordToLabelBhv elevateWordToLabelBhv;

    /** Behavior handler for ElevateWord entity operations */
    @Resource
    protected ElevateWordBhv elevateWordBhv;

    /** Behavior handler for LabelType entity operations */
    @Resource

            if (host == null) {
                return;
            }

            // Atomically get or create the AtomicLong for this host using Cache.get()
            // This ensures thread-safe, atomic get-or-create behavior
            // Initialize with 0 to mark uninitialized state
            final AtomicLong lastTime = lastTimes.get(host, () -> new AtomicLong(0));

            synchronized (lastTime) {

 * Provides a common structure for handling delays at different stages of the crawling process.
 * It encapsulates the delay logic and exception handling, allowing subclasses to focus on
 * defining the specific delay behavior for each stage.

 * <p>
 * This class defines the contract for delaying the crawling process at various points, such as:

 * <ul>

            assertFalse("validateCalled should be false as exception thrown before flag set", extractor.isValidateCalled());
        }
    }

6. Update JavaDoc

### When Fixing Bugs

1. Write failing test first
2. Understand root cause
3. Minimal changes
4. Verify no regressions

### When Refactoring

1. Preserve behavior
2. Keep tests green
3. Small incremental steps
4. Don't mix with new features

### Code Quality Checklist

- [ ] Java conventions followed
- [ ] JavaDoc for public APIs
- [ ] Tests pass (`mvn test`)

 * This class provides common functionality for job execution including process management,
 * logging configuration, JVM options, and timeout handling.
 *
 * <p>Subclasses must implement the abstract methods to define specific job behavior
 * and execution type identification.</p>
 *
 * @version 1.0
