## 1. Role

### JBSbatKKKojiKnrnInfToroku.createKojiRsvInfNet()

This method performs the **Construction Schedule Information (Network) Registration** processing for a batch job. It reads a CSV file containing construction schedule records for network services (Fiber-to-the-Home / broadband infrastructure), parses each row, maps the comma-delimited fields into a structured parameter list, and inserts the data into the `KK_T_KJ_RSV_WK` work table. The method is called during the nighttime batch processing window as the first of several construction-info output routines.

The service category handled by this method is **network-type construction scheduling** (distinct from the TV-type counterpart `createKojiRsvInfTv`). All records are written with a fixed construction project service type code of `"01"` (Home/Network), indicating these are residential broadband installation schedules.

The method implements a **batch record-by-record insert pattern**: it reads a file, iterates rows, transforms field data (filling missing values with a half-width space), and delegates the actual database write to the private method `executeKK_T_KJ_RSV_WK_PKINSERT`. It serves as a **delegating batch processor** called from the `execute()` entry point.

No conditional branches based on service type exist within this method — it processes all rows uniformly as network-type construction schedule records.

## 5. Dependency Trace

### Pre-computed evidence from code analysis graph:

No screen/batch entry points found within 8 hops. Direct callers found: 1 methods.
Terminal operations from this method: `printDebugLog` [-], `printDebugLog` [-], `printDebugLog` [-], `printDebugLog` [-], `printDebugLog` [-], `executeKK_T_KJ_RSV_WK_PKINSERT` [C], `toArray` [-], `split` [-], `split` [-], `split` [-], `split` [-], `getInputFile` [R], `getSystemDateTimeStamp` [R], `printDebugLog` [-], `printDebugLog` [-], `printDebugLog` [-], `printDebugLog` [-], `printDebugLog` [-]

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: JBSbatKKKojiKnrnInfToroku | `JBSbatKKKojiKnrnInfToroku.execute()` -> `createKojiRsvInfNet(mid_dir_kk)` (called within `if SPACE.equals(dayFlg)` nighttime processing block) | `executeKK_T_KJ_RSV_WK_PKINSERT [C] KK_T_KJ_RSV_WK` |

**Call chain detail:** The `execute()` method of `JBSbatKKKojiKnrnInfToroku` is the batch entry point. When `dayFlg` equals `SPACE` (empty string, indicating nighttime processing), it invokes `createKojiRsvInfNet(mid_dir_kk)` as the first of several sequential construction-info output routines. After this method completes, the batch continues with `createKojiRsvInfTv`, `createKikiInfNet`, `createKikiInfTv`, and other similar construction info methods.

**Terminal operations** (operations ultimately performed by this method):
- `executeKK_T_KJ_RSV_WK_PKINSERT [C] KK_T_KJ_RSV_WK` — Creates a record in the construction schedule work table
- `printDebugLog` [-] — Multiple debug log calls (entry, exit, intermediate)
