# Com / Optage

## Overview

The `com.optage` package serves as the top-level namespace for the Optage application codebase. It appears to be a modular enterprise application that handles a range of operational capabilities — batch job processing, Send-Off-Dispatch (SOD) workflow orchestration, contract processing, emergency shutdown control, and data transfer.

At present, `com.optage` contains one directly indexed sub-package: `kopt`, which organizes the bulk of the observable functionality. The package structure follows a feature-oriented subpackage layout where each subpackage groups related classes by domain responsibility.

Most of the code in `com.optage` currently consists of auto-generated fixture stubs designed for SPEC-SCOPED-WIKI test scaffolding. Method bodies contain inline comments such as `/* SOD dispatch logic */` or `/* Contract processing */` indicating intended but unimplemented business logic. Developers should treat the existing code as scaffolding rather than production-ready implementation.

## Sub-module Guide

### com.optage.kopt — KOPT Application Subsystem

The `kopt` subpackage is the primary observable module within `com.optage`. It organizes capabilities into named subpackages:

- **`batch`** — Batch job processing entry points. Contains procedure classes (`KKPRC14901`, `KKPRC24901`, `KKPRC34901`) following a common `run()` signature. Only `KKPRC14901` has real wiring: it delegates to `ekk` for contract processing.
- **`bp`** — SOD (Send-Off-Dispatch) workflow orchestration. The central class `JKKHakkoSODCC` coordinates dispatch and validation flows, making it the coordination hub for the SOD subsystem.
- **`dto`** — Request/response data transfer objects for SOD operations. Minimal, behaviorless containers scoped by `tenantId` and `serviceId`.
- **`ekk`** — Contract processing. `EKK0301A010` is the primary processor; its `notify()` method delegates to `kkw` for notifications.
- **`esc`** — Emergency shutdown controller. A single isolated stub class with no outgoing dependencies.
- **`kkw`** — KKW batch trigger. Downstream leaf of `ekk`, with a no-op `trigger()` stub.
- **`unrelated`** — Self-contained test artifact with zero behavior.

**How they relate:** While most subpackages are independently scaffolded stubs, several meaningful interaction paths exist:

1. `bp` (SOD workflow) coordinates the primary data flow — it uses `dto` for data, delegates to `batch` for validation, and internally dispatches via `JKKSodSendCC`.
2. `batch` delegates to `ekk` for contract processing (`KKPRC14901` -> `EKK0301A010`).
3. `ekk` delegates to `kkw` for notifications (`EKK0301A010.notify()` -> `KKW0100B001.trigger()`).
4. `esc` and `unrelated` stand alone with no cross-package links.

The most active conceptual data flow follows: `bp` (orchestrates) -> `dto` (carries request) -> `batch` (validates) -> `ekk` (contracts) -> `kkw` (notifications).

## Key Patterns and Architecture

### Fixture / Stub Pattern
Almost every class across `com.optage.kopt` is an auto-generated fixture for test scaffolding. Method bodies contain placeholder comments indicating intended behavior that has not yet been implemented. This pattern should be treated as scaffolding, not production code.

### Delegation over Composition
The few classes with active code use a simple delegation pattern — creating target classes inline and calling methods on them, without factories or dependency injection. Examples include `KKPRC14901` delegating to `EKK0301A010`, `JKKHakkoSODCC` creating `JKKSodSendCC`, and `EKK0301A010` creating `KKW0100B001`.

### Naming Convention
Classes follow a structured pattern: a subsystem prefix (`KK`, `ESC`, `JKK`) followed by a numeric code encoding a spec identifier and component variant. Batch procedures use the `KKPRC` prefix with sequential numbering.

### Request/Response DTO Structure
The `dto` package provides minimal data shape containers for the SOD workflow, decoupling data from service logic. These will need augmentation with accessors, constructors, and serialization annotations for production use.

## Dependencies and Integration

### Internal Dependencies

| Source Package | Target Package | Nature of Dependency |
|---|---|---|
| `com.optage.kopt.batch` | `com.optage.kopt.ekk` | `KKPRC14901.run()` instantiates `EKK0301A010` |
| `com.optage.kopt.bp` | `com.optage.kopt.batch` | `JKKHakkoSODCC.validate()` calls `KKPRC14901.check()` |
| `com.optage.kopt.ekk` | `com.optage.kopt.kkw` | `EKK0301A010.notify()` instantiates `KKW0100B001` |
| `com.optage.kopt.bp` | `com.optage.kopt.dto` | SOD workflow uses request/response DTOs |

### External Dependencies

No external package dependencies were detected at the package level. The only external (test-scope) dependency is JUnit, used by `JKKHakkoSODCCTest` in the `bp` package.

## Notes for Developers

- **Most code is stubs**: The vast majority of classes in `com.optage` are auto-generated fixtures. Do not assume any non-stub class represents finished business logic. Always check the method body for placeholder comments before relying on behavior.
- **Only two classes have meaningful wiring**: `KKPRC14901` (batch -> ekk delegation) and `EKK0301A010` (ekk -> kkw notification) are the only classes with actual cross-package references beyond stubs.
- **`bp` is the coordination hub**: If you are tracing the SOD workflow, start in `bp`. It connects to `batch` (validation), `dto` (data), and `bp` internals (`JKKSodSendCC`, `JKKHakkoSODHelper`).
- **`esc` and `unrelated` are isolated**: Neither subpackage has incoming or outgoing dependencies. `esc` is a standalone emergency shutdown scaffold; `unrelated` is a test artifact with zero behavior.
- **Naming conventions are consistent**: When adding new classes, follow the prefix + numeric code pattern used across subpackages. New batch procedures should use the `KKPRC` prefix with sequential numbers.
- **DTOs need augmentation**: The `dto` classes are plain field containers with no accessors, constructors, or serialization annotations. Production use will require generating or adding these.
- **`JKKHakkoSODHelper.format()` is the only concrete utility**: Of all classes in the package, this is the only one with a non-trivial, non-stub implementation. It trims whitespace from a string input with no null safety.
