## 1. Role

### FUW01403SFLogic.executeInitService()

This method implements the **initial screen display** processing for the "2 Number Service Application" (2番号サービスお申し込み) — a telecom service contract flow where customers apply for a second telephone number on the same line. It is the entry-point service logic that orchestrates all data gathering required to render the initial application screen.

The method follows a **mapper-based upper/lower mapping pattern** (アッパーマッピング／ダウンマッピング). It first populates an `inputMap` with SC (Service Component) and CC (Common Component) request parameters via the `FUSV0041_FUSV0041OPDBMapper` — covering service contract information display, price plan lists, device option service lists, initial fee breakdowns, ONU exchange work eligibility, and work skip possibility judgments. After invoking the underlying service chain through `invokeService(paramMap, inputMap, outputMap)`, it retrieves all results back into the form beans via corresponding `get*` (lower mapping) calls.

The method also handles **mansion (apartment) vs. detached house judgment** to determine whether to include mansion-specific initial fee items (service handling fees). Additionally, it computes a display flag (`CHG_MULTI_PHONE_CALL_MSG_DSP_FLG`) that controls whether an advisory message about multi-line change processing should be shown — determined by whether the customer has zero multi-phone registrations but non-zero warikomi (bundled) phone registrations.

It is called as the service handler from `FUW01403SFLogic.init()`, which serves as the screen entry point dispatching initialization actions to this method.

**CONSTANT resolutions used in flowchart:**
- `MANSION_JUDGE_FLG = "マンション判定フラグ"` (mansion judgment flag parameter key)
- `CON_MANS_FLG = "1"` (is mansion constant — indicates the customer is in a mansion/apartment building)
- `SVC_USECASE_ID_FUSV0041 = "FUSV0041"` (use case ID for the service component mapping)
- `JPCModelConstant.FUNC_CD_1` (function code 1 — typically indicates display/initialization operation)

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `commonInfoBean` | `final X31SDataBeanAccess` | Shared form Bean carrying common customer and session information (e.g., customer ID, access authority, operation date, and shared flags) used as context across all service processing in this module. Passed to `serviceFormBeanArray2` for CC-level methods requiring both form and common info. |
| 2 | `serviceFormBean` | `final X31SDataBeanAccess` | 2 Number Service Application form Bean carrying screen-specific data: service type number (`SVC_KEI_NO`), mansion judgment flag (`MANSION_JUDGE_FLG`), and all fields that will be populated by upper/lower mapping for display on the initial application screen. |

**External state read by this method:**

| Field / Source | Type | Business Description |
|---------------|------|---------------------|
| `this.getCommonInfoBean()` | `X31SDataBeanAccess` | Instance field accessor — retrieves the instance-level common info Bean (used alongside `serviceFormBean` in `serviceFormBeanArray2` for CC methods that need both contexts). |
