# Com / Optage / Kopt / Ekk

## Overview

The `com.optage.kopt.ekk` package is a subpackage under `com.optage.kopt` that contains fixture classes used for SPEC-SCOPED-WIKI tests. It provides minimal stub implementations — `EKK0301A010` and `EKK0301A020` — which serve as test placeholders to validate the wiki generation pipeline for the EKK module scope. These classes delegate to or reference classes in the sibling package `com.optage.kopt.kkw` (specifically `KKW0100B001`), establishing a cross-package dependency.

## Key Classes and Interfaces

### EKK0301A010

**Source:** [`EKK0301A010.java`](src/main/java/com/optage/kopt/ekk/EKK0301A010.java)

`EKK0301A010` is the primary fixture class in this package. It represents the main contract processing entry point (as labeled in the comment) and coordinates with related modules via its `notify()` method.

**Methods:**

| Method | Description |
|--------|-------------|
| `process()` | A no-op stub representing contract processing. It exists as a structural placeholder for test contracts that exercise the EKK module. |
| `notify()` | Instantiates and triggers a `KKW0100B001` object by calling its `trigger()` method. This is the package's only cross-module interaction, reaching into the `com.optage.kopt.kkw` package. |

The class follows a simple command-like pattern: an external caller would invoke `process()` to handle the contract, and `notify()` to send a side-effect signal to a downstream handler in the `kkw` package.

### EKK0301A020

**Source:** [`EKK0301A020.java`](src/main/java/com/optage/kopt/ekk/EKK0301A020.java)

`EKK0301A020` is a secondary fixture class providing a supplementary contract processing entry point. It mirrors `EKK0301A010`'s structure but does not reference any external classes.

**Methods:**

| Method | Description |
|--------|-------------|
| `process()` | A no-op stub for secondary EKK contract processing. It provides a distinct code path from `EKK0301A010` for test coverage. |

## How It Works

Since both classes are auto-generated fixture stubs for wiki-generation tests, the "flow" is intentionally minimal:

1. An external test harness instantiates `EKK0301A010` or `EKK0301A020`.
2. Calling `process()` on either class exercises the structural presence of the EKK module in the codebase (currently a no-op placeholder).
3. Calling `EKK0301A010.notify()` creates a transient `KKW0100B001` instance and calls `trigger()`, establishing a sample cross-module call chain that the test framework can use to verify inter-module reference tracking.

## Data Model

This module does not define any data model classes, DTOs, entities, or fields. Both classes are pure stubs with void-returning methods and no state.

## Dependencies and Integration

| Dependency | Direction | Description |
|------------|-----------|-------------|
| `com.optage.kopt.kkw` | Outgoing | `EKK0301A010.notify()` creates and calls `KKW0100B001.trigger()`. This is the only cross-module dependency in the package. |

## Notes for Developers

- **These classes are auto-generated fixtures.** They exist to support the SPEC-SCOPED-WIKI test infrastructure and are not production business logic. Any real EKK contract-processing behavior would be implemented in a future iteration once the wiki-generation scaffolding is validated.
- **No child modules exist yet.** The `ekk` package has no further subpackages, so this wiki page covers the entirety of the module.
- **Cross-module reference:** `EKK0301A010` is the sole bridge to `com.optage.kopt.kkw` via `KKW0100B001`. If the `kkw` module changes its API (e.g., the `KKW0100B001` constructor or `trigger()` signature), this package would need to be updated accordingly.
