## 1. Role

### KKW00129SF03DBean.typeModelData()

This method is a **data type routing and dispatch** utility used by the Futurity X33 web framework to dynamically determine the Java type of individual UI data fields within the "Service Contract <EO Optical TV> Consent Information" (サービス契約〈eo光TV〉一意向情報) screen. It implements the `X33VDataTypeBeanInterface.typeModelData(String key, String subkey)` contract: when the X33 framework needs to know what Java type a given field should be rendered as (e.g., for dynamic form binding, type-safe data loading, or HTML input generation), it calls `typeModelData` with a human-readable field label (`key`) and a property sub-key (`subkey`). The method matches the field label against **13 domain-specific telecom service fields** related to EO Optical TV subscription management, and for each field, maps the subkey to an appropriate Java type — `String.class` for value and state, `Boolean.class` for enabled/disabled flags. It follows a **routing/dispatch design pattern** using a chain of `if-else` branches — each branch handles one field label and three subkey cases. This method has **no side effects** — it is purely a read-only type introspection utility with no database access, no service calls, and no mutation of instance state. It plays the role of a **shared framework adapter**, enabling the X33 framework to generate type-safe dynamic form components without hardcoding field types in view templates.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The human-readable Japanese field label identifying which data field's type is being queried. Maps to internal item IDs (e.g., `svc_kei_no` for service contract number, `gene_add_dtm` for generation registration datetime). Each value corresponds to a specific UI-bound field on the EO Optical TV consent information screen. |
| 2 | `subkey` | `String` | A property sub-key within the field that determines which aspect's type to return. Three valid values: `"value"` (the data value of the field), `"enable"` (whether the field is enabled/disabled for editing), and `"state"` (the current state status of the field). Comparisons are case-insensitive (`equalsIgnoreCase`). |

**Instance fields read:** None — this method is stateless. It does not access any protected instance fields of `KKW00129SF03DBean`.

**Local variables:**
| Variable | Type | Business Description |
|----------|------|---------------------|
| `separaterPoint` | `int` | Holds the result of `key.indexOf("/")` — the index of the first forward slash in the key. This value is computed but never used in any conditional logic, suggesting it may be a leftover from a planned future enhancement (e.g., slash-delimited multi-key routing). |

## 4. CRUD Operations / Called Services

This method performs **no CRUD operations** and calls **no services or data-access methods**. It is a pure type-introspection router with zero side effects. No database queries, no entity manipulation, no service component invocations.

## 5. Dependency Trace

This method is an interface implementation of `X33VDataTypeBeanInterface.typeModelData()`. It is called indirectly by the X33 framework when the framework needs to determine the Java type of a dynamic form field. The method is also instantiated and registered in the parent bean `KKW00129SFBean` (see the constructor section where a new `KKW00129SF03DBean` instance is added to the `ekk0101a010cbsmsg1list_list` collection).

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKW00129SF | `KKW00129SFBean` constructor adds `KKW00129SF03DBean` to `ekk0101a010cbsmsg1list_list` → X33 framework invokes `typeModelData` | N/A (pure type routing, no data access) |
| 2 | Screen:KKW00129SF | `KKW00129SFBean` constructor (koptWebB) adds `KKW00129SF03DBean` to `ekk0101a010cbsmsg1list_list` → X33 framework invokes `typeModelData` | N/A (pure type routing, no data access) |

**Note:** The X33 framework calls `typeModelData` during the `loadModelData` / `saveModelData` lifecycle of `X33VDataTypeBeanInterface`-implementing beans. The framework passes the human-readable field label as `key` and the property sub-key as `subkey` to resolve the appropriate Java type at runtime.

## 6. Per-Branch Detail Blocks
