## 1. Role

### ValuesPicker.transform()

This method serves as a **data mapping transformer** that extracts discount and promotion (割引・Promotion) information from a CBS (CBS: Customer Billing System) message and normalizes it into a standardized `HashMap<String, String>` output. It implements the **Transformer design pattern**, taking a `CAANMsg` input envelope and producing a flat key-value map suitable for downstream screen binding or business logic consumption.

The method performs **conditional branching** based on the "Discount/Discriminated Judgment Code" (`WRIB_DCHS_HAMBET_CD`). When the code equals `"1"`, the method processes the record as a **discount service** (割引サービス), setting `kei_kind` to `"w"` (WRIB — 割引), and applies special date logic: if the start date (`staymd`) is a placeholder value of `20991231` (meaning "unspecified/infinite"), it calculates the actual start date as the day after the end date plus one. When the code is anything else, it processes the record as a **non-discount service** (非割引), setting `kei_kind` to `"d"` (HNSOKU — 非割引).

In the non-discount branch, an additional business rule handles **network-phone-TV three-way applications** (ネッ電話TV三点申込): if the service discount code equals `"DT0000002"`, the method clears both `staymd` (start date) and `endymd` (end date) to empty strings, as these services do not have fixed term start/end dates.

The method was refactored in **v5.00.20** to consolidate discount/promotion data retrieval into a single service IF (CBS message `EKK0451B011CBSMsg1List`), removing the need for a separate older message (`EKK0451B005CBSMsg1List`). A second refactoring in **v5.00.24** introduced the placeholder start date calculation logic to handle cases where the start date is not explicitly set.

**Processing Summary:**

1. **Initialization**: Create a `HashMap` with `DEFAULT_HASH_SIZE` (typically 50) for the output.
2. **Branch Detection**: Read the discount discrimination judgment code (`WRIB_DCHS_HAMBET_CD`) from the input message. This determines whether the service is a discount type or non-discount type.
3. **Discount Branch** (keiKind == "1"): The `kei_kind` is set to `"w"` (割引/Discount). For the start date, if the system returned a placeholder end-of-range date (`20991231`), the actual start date is calculated as one day after the end date using `JPCDateUtil.addDay(eYmd, 1)`.
4. **Non-Discount Branch** (keiKind != "1"): The `kei_kind` is set to `"d"` (非割引/Non-Discount). The start date is read directly from the input. Additionally, if the service code is `"DT0000002"` (Network-Phone-TV three-way application), both start and end dates are cleared to empty strings.
5. **Common Field Mapping**: Both branches map the same set of output keys, differing only in `kei_kind`, `staymd` (in the discount branch, possibly adjusted), and `endymd` (potentially cleared in the non-discount special case).
