## 1. Role

### FUW01403SFLogic.executeCfmMskmService()

This method implements the core service execution processing for the **Two-Number Service Application (Confirmation/Application)** screen (2番号サービスお申し込み(確認/申込)). It orchestrates the complete submission pipeline for a customer's two-number service contract — a telecom service that consolidates multiple phone numbers under a single unified contract while maintaining individual number identities for caller ID purposes. The method follows a **routing/dispatch** and **delegation** design pattern: it first populates a structured `inputMap` by chaining a sequence of data mapping and SC (Service Component) calls through the `FUSV0042_FUSV0042OPDBMapper` class, then delegates the actual business transaction to the remote service via `invokeService()`. The method handles two distinct service pathways based on the `noTchSvcUm` (non-transfer service management) flag: if set to `"1"`, it processes **optional service contract registration and start** workflows; otherwise, it processes **optional service contract cancellation and consent withdrawal** workflows. After service execution, it retrieves the results via `getFUSV004201CC()` and returns the structured output map to the caller. This method serves as the primary entry point from the two-number service application screen's `cfm()` and `mskm()` processing paths, acting as the critical bridge between the web presentation layer and the backend telecom service orchestration.

**Constant Resolution Notes:**
- `FUW01403SFConst.TELNO` = `"番号ポートatilityを利用する電話番号"` (Phone number using number portability) — identifies whether the customer is porting an existing phone number.
- `FUW01403SFConst.NO_TCH_SVC_UM` = `"発信者番号通知有无"` (Outbound caller number notification presence/absence) — flag that determines whether optional service management is active.
- `NO_TCH_SVC_UM_1` = `"1"` — when `noTchSvcUm` equals `"1"`, the customer has confirmed optional service registration (service start path); any other non-null value triggers the cancellation path.
- `SVC_USECASE_ID_FUSV0042` = `"FUSV0042"` — the use-case identifier for the FUSV0042 service transaction.
- `JPCModelConstant.FUNC_CD_1` and `JPCModelConstant.FUNC_CD_2` — function code constants used to differentiate service modes in SC calls.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `commonInfoBean` | `final X31SDataBeanAccess` | Shared form bean carrying common screen context data (session info, authentication details, and shared UI state) that is accessible across the two-number service application flow. Retrieved via `getCommonInfoBean()`. |
| 2 | `serviceFormBean` | `final X31SDataBeanAccess` | Service-specific form bean containing the two-number service application data — including phone numbers, customer address information, service contract details, and optional service management flags. This is the primary data carrier that flows through all mapping and SC operations. |
| 3 | `funcCode` | `final String` | Function code identifying the specific processing mode or screen invocation context. Passed through to multiple SC mapping methods to differentiate between different operational modes (registration vs. modification, etc.). |

**External state read:**
| Field | Type | Business Description |
|-------|------|---------------------|
| `this` (FUW01403SFLogic instance) | `FUW01403SFLogic` | The logic class instance containing inherited utility methods (`isNull()`, `handleMskmException()`), the `DEBUG_LOG` logger, and access to common info via `getCommonInfoBean()`. |
| `DEBUG_LOG` | Logger | Debug logging instance for tracing method execution boundaries. |

The `cfm()` and `mskm()` methods are both CBS (Core Business Service) methods within the same `FUW01403SFLogic` class. `cfm()` handles the confirmation flow (確認), and `mskm()` handles the application/registration flow (申込). Both delegate to `executeCfmMskmService()` for the actual service execution, differing only in how they prepare their input data before this method is called.
