# Com / Optage / Kopt / Batch

## Overview

The `com.optage.kopt.batch` package contains three auto-generated fixture classes (`KKPRC14901`, `KKPRC24901`, `KKPRC34901`) used for SPEC-SCOPED-WIKI testing. These classes serve as minimal test stubs within the KOPT (key optimization / batch processing) subsystem. `KKPRC14901` delegates work to a class in the `com.optage.kopt.ekk` package, while `KKPRC24901` and `KKPRC34901` are currently no-op stubs marked as "secondary" and "tertiary" batch operations respectively.

## Key Classes and Interfaces

### KKPRC14901

Primary batch entry point for SPEC-SCOPED-WIKI tests. It exposes two methods:

- **`check()`** — A placeholder method with no implementation. Appears intended as a hook for validation or pre-condition checks before running the batch, but currently does nothing.
- **`run()`** — The main entry point. Instantiates and calls `process()` on an `EKK0301A010` object from the `com.optage.kopt.ekk` package. This is the only class in the batch package that performs any actual work (delegating outward).

### KKPRC24901

Secondary batch fixture. Currently contains only a no-op `run()` method with a comment indicating it represents a "secondary batch" operation. No other methods or state.

### KKPRC34901

Tertiary batch fixture. Structurally identical to `KKPRC24901` — a single no-op `run()` method labeled as a "tertiary batch" operation.

## How It Works

The package follows a simple delegation pattern:

1. A test harness or batch scheduler invokes `run()` on one of the three `KKPRC*` classes.
2. `KKPRC14901.run()` delegates to `EKK0301A010.process()`, offloading the actual batch logic to the `com.optage.kopt.ekk` package.
3. `KKPRC24901.run()` and `KKPRC34901.run()` are no-ops — no logic executes.

There is no input/output handling, no configuration, and no state management across these classes. Each class is standalone with no shared interfaces or abstract base class (beyond the implicit `java.lang.Object`).

## Dependencies and Integration

| Dependency | Direction | Purpose |
|---|---|---|
| `com.optage.kopt.ekk` | Outbound | `KKPRC14901.run()` creates and calls `EKK0301A010` |

This is a leaf module with no child sub-packages. It has no dependencies on `com.optage.kopt.batch` from outside the package other than `com.optage.kopt.ekk`.

## Notes for Developers

- These classes are **auto-generated fixtures** for test infrastructure (SPEC-SCOPED-WIKI). They should not be treated as production code. Do not add business logic directly here — if real batch behavior is needed, it belongs in the `com.optage.kopt.ekk` package or a non-test package.
- The naming convention (`KKPRC` + 5-digit suffix) appears to be code-generated and may not map to human-readable batch operation names.
- `KKPRC14901.check()` exists but is unimplemented. If a pre-flight validation step is ever needed, this is the intended hook.
- There are no constructors, no fields, no logging, and no error handling across any of the three classes.
