## 1. Role

### JBSbatKKNrkeFinKikiHktgi.terminal()

This method implements the business service termination (lifecycle teardown) processing for the "eo Light Net Single Plane" equipment succession batch job. Its sole responsibility is to release all database resource handles that were acquired during the batch processing lifecycle, ensuring proper cleanup regardless of whether the batch completed successfully or terminated abnormally. The method follows the resource cleanup design pattern commonly used in batch service frameworks, where a `terminal()` lifecycle hook is guaranteed to execute after the main processing completes (typically via a `finally` block in the parent framework's invocation chain). As a resource cleanup method with no conditional branches or data mutations, it serves as a defensive safeguard against database connection leaks and file descriptor exhaustion during long-running batch operations. It is part of the class whose purpose is handling equipment succession processing after the completion of net-to-single-plane migration, and also outputs succeeded equipment information to the "Equipment Succession Completion List" file.

**Processing Description:**
The `terminal()` method executes a flat, sequential chain of 17 `close()` calls. There are no conditional branches, no loops, and no error handling logic within the method itself. Each `close()` call releases a database SQL access handle (`JBSbatSQLAccess`) that was opened during the batch job's processing phase. The handles are closed in the reverse order of their typical lifecycle acquisition, following a structured resource cleanup pattern. The additional handle `db_KU_T_KJAK_TG_TKKIKI` (Work Case Target Indoor Equipment) was added in version v74.00.00 under ticket ANK-4656-00-00 for the "eo Light Single Plane Provision (STEP3)" feature.

**Notes:**
- All operations are resource release calls (`close()`) on `JBSbatSQLAccess` objects. These are not CRUD operations against the database — they are framework-level resource cleanup calls that release database connections, statements, and result sets back to the pool.
- No SC codes (Service Component codes) are present because this method does not invoke service components; it only performs resource teardown.

## 5. Dependency Trace

The `terminal()` method is defined as an abstract method in the parent class `JBSbatBusinessService` and is implemented as a lifecycle hook. It is invoked automatically by the batch processing framework (typically in a `finally` block) after the main business processing completes — either successfully or due to an exception. No explicit callers were found in the codebase beyond the framework inheritance chain.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch Framework | `JBSbatBusinessService.execute()` (framework) -> `JBSbatKKNrkeFinKikiHktgi.terminal()` | `close(ZM_M_WORK_PARAM_KNRI) [RES] ZM_M_WORK_PARAM_KNRI`<br>`close(KK_T_KKTK_SVC_KEI) [RES] KK_T_KKTK_SVC_KEI`<br>`close(KK_T_KKTK_SVC_KEI_SAKI) [RES] KK_T_KKTK_SVC_KEI_SAKI`<br>`close(KK_T_SVC_KEI) [RES] KK_T_SVC_KEI`<br>`close(KK_T_KKOP_SVC_KEI) [RES] KK_T_KKOP_SVC_KEI`<br>`close(DK_T_HAISO_TG_BPIN) [RES] DK_T_HAISO_TG_BPIN`<br>`close(DK_T_HMPIN_KIKI) [RES] DK_T_HMPIN_KIKI`<br>`close(DK_T_HMPIN_KIKI_MOTO) [RES] DK_T_HMPIN_KIKI_MOTO`<br>`close(KK_T_SVKEI_KAISEN_UW) [RES] KK_T_SVKEI_KAISEN_UW`<br>`close(KK_T_ODR_SET) [RES] KK_T_ODR_SET`<br>`close(KK_T_SVC_KEI_UCWK) [RES] KK_T_SVC_KEI_UCWK`<br>`close(KK_T_ODR_HAKKO_JOKEN) [RES] KK_T_ODR_HAKKO_JOKEN`<br>`close(KK_T_ODR_INF_SKSI_WK) [RES] KK_T_ODR_INF_SKSI_WK`<br>`close(KK_T_PRG) [RES] KK_T_PRG`<br>`close(KU_T_KJAK_TG_TKKIKI) [RES] KU_T_KJAK_TG_TKKIKI` |

**Legend:** `[RES]` = Resource release (close) — not a database CRUD operation.

## 6. Per-Branch Detail Blocks

The `terminal()` method has no conditional branches, loops, or nested blocks. It consists of a flat sequence of 17 resource cleanup calls. Below is the complete block analysis:

**Block 1** — [SEQUENCE] `(terminal method body, lines 1317–1334)`

> This is the complete method body. It contains no conditions, no loops, and no try/catch. The method simply executes sequential close() calls to release all DB resource handles.
