## 1. Role

### JBSbatKKKojiKnrnInfToroku.createKojiRsvInfTv()

This method performs the **construction schedule information (TV) registration processing** — it reads a pre-mashed CSV file containing work schedule data for television-related construction activities, transforms each CSV row into a structured parameter array of 33 fields, and inserts the records into the construction schedule work table (`KK_T_KJ_RSV_WK`). The method acts as a **batch data ingestion pipeline** within the larger construction information registration subsystem: it is a shared service method called by the batch orchestrator `execute()`, which manages multiple similar registration methods for different service types (Network, TV, etc.). The design pattern used is a **read-transform-write** loop: read raw CSV lines from an intermediate file directory, map/transform each line to a domain-specific parameter list with type code `03` (TV) hardcoded for the `KOJIAK_SVC_SBT_CD` field, fill missing fields with half-width spaces (or `"0"` for STB count), and insert into the database via primary-key-based insertion. The method handles one specific service type category: **TV (television) construction schedule** identified by the constant `KOJIAK_SBT_CD_TV = "03"`.
