# Business Logic — JBSbatKKCustDelTrgtCst.terminal() [7 LOC]

| Field | Value |
|-------|-------|
| Fully Qualified Name | `eo.business.service.JBSbatKKCustDelTrgtCst` |
| Layer | Service (Batch Business Service) |
| Module | `service` (Package: `eo.business.service`) |

## 1. Role

### JBSbatKKCustDelTrgtCst.terminal()

The `terminal()` method serves as the **lifecycle cleanup callback** in the business service template pattern implemented by the K-Opticom eo Customer Base System. This system is responsible for customer deletion target extraction (お客様消去対象抽出部品 — "Customer Deletion Target Extraction Component"). The method is invoked at the end of the business service lifecycle, following `initial()` (initialization) and `execute()` (main processing), as part of the `JBSbatBusinessService` abstract base class contract. Its role is to provide a hook for any resource cleanup, transaction rollback handling, or post-processing teardown required after the customer deletion target processing completes. Currently, this method is a **stub** — it contains no executable logic beyond the tool-generated start and end markers, meaning no post-processing cleanup is required for this particular business service. The actual business work of extracting customer deletion targets is performed entirely in the `execute()` method, which assembles output records for aging-updated deletion targets, distinguishing between eoID-based and nickname-based deletion scopes.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid

    START(["terminal() Entry"])
    TOOL_MARKER_START["Tool-Generated: Terminal Processing Start Marker"]
    TOOL_MARKER_END["Tool-Generated: Terminal Processing End Marker"]
    END_NODE(["Return"])

    START --> TOOL_MARKER_START --> TOOL_MARKER_END --> END_NODE
```

This method contains no conditional branches, loops, or method calls. It is a pure lifecycle callback stub that proceeds directly from entry to exit. The tool-generated markers (`ツールから生成した終了処理のソースです` — "Source of terminal processing generated from tool") serve as insertion points for code generated by the enterprise development tooling but are not executed logic.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | This method takes no parameters. It is a parameterless lifecycle callback inherited from `JBSbatBusinessService`. |

**Instance fields read by this method:** None. The method body contains no field accesses or external state reads.

## 4. CRUD Operations / Called Services

This method makes **no method calls**. No CRUD operations are performed. The `terminal()` callback is a no-op stub.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| — | (no calls) | — | — | This method contains no business logic or data access. |

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | (internal) | `JBSbatBusinessService.run()` (template lifecycle) -> `JBSbatKKCustDelTrgtCst.terminal` | (no terminal calls) |

**Notes:**
- The `terminal()` method is called internally by the `JBSbatBusinessService` base class as part of its lifecycle management template (after `execute()` completes, whether successfully or with an exception).
- No external screen, batch, or CBS layer directly invokes this method. It is an internal lifecycle hook.
- The `execute()` method (the primary entry point) outputs deletion target configuration records: it produces two output maps when both eoID and nickname (`NKNAME`) data are present, or a single output map when only eoID is present.

## 6. Per-Branch Detail Blocks

**Block 1** — [METHOD ENTRY] `(void terminal() throws Exception)` (L108)
