## 1. Role

### FUW00943SF02DBean.listKoumokuIds()

This method serves as a static metadata provider for the FUW00943SF survey display module, returning a fixed ordered list of six field labels used throughout the survey (enquete) UI screens. These field names — including "アンケート内容" (Survey Content), "アンケートチェック種類" (Survey Check Type), "アンケート番号" (Survey Number), "表示順序（アンケート内容）" (Display Order (Survey Content)), "ラジオボタン選択肢" (Radio Button Choices), and "アンケート回答リスト" (Survey Answer List) — represent the columns or data items that appear in survey-related table views, forms, and data binding layers. The method implements a simple factory/builder pattern: it constructs a new `ArrayList<String>`, appends each field name in a deterministic order, and returns the collection for downstream consumers. Its role in the larger system is as a shared data-bean utility called by parent DBean classes across multiple survey screen modules (FUW00912SF, FUW00926SF, FUW00959SF, FUW00964SF) to populate display metadata for survey answer lists, enabling consistent column ordering and field identification across screens without hardcoding labels at each call site.

The method performs a single linear sequence of operations with no conditional branches, loops, or external service calls. It instantiates a new `ArrayList<String>`, adds six survey-related field names in a fixed order via `add()` calls, and returns the populated list.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | - |

This method takes no parameters. It operates purely as a stateless factory, constructing and returning a new list each time it is invoked.

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| - | - | - | - | - |

This method performs no CRUD operations, no database access, and no calls to service components (SC) or common business services (CBS). It is a pure in-memory data builder.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | FUW00912SF (Survey Module) | `FUW00912SFBean.listKoumokuIds(key)` → `FUW00912SF01DBean.listKoumokuIds()` | (none — pure bean) |
| 2 | FUW00926SF (Survey Module) | `FUW00926SFBean.listKoumokuIds(key)` → `FUW00926SF01DBean/02DBean/03DBean.listKoumokuIds()` | (none — pure bean) |
| 3 | FUW00959SF (Survey Module) | `FUW00959SFBean.listKoumokuIds(key)` → `FUW00959SF01DBean/02DBean/03DBean/04DBean.listKoumokuIds()` | (none — pure bean) |
| 4 | FUW00964SF (Survey Module) | `FUW00964SFBean.listKoumokuIds(key)` → `FUW00964SF01DBean/02DBean/.../11DBean.listKoumokuIds()` | (none — pure bean) |

The `listKoumokuIds()` method is called exclusively by parent DBean classes within the survey (`FUW`-prefixed) screen modules. Each caller's `listKoumokuIds(String key)` method routes to a specific child DBean's static `listKoumokuIds()` based on the `key` parameter value. The terminal result is a simple list of field name strings used for UI display metadata — no downstream service or database calls originate from this method.
