## 1. Role

### FUW00943SFLogic.selectMansionMngn()

This method assembles and returns a `StringBuilder` containing all message strings displayed during the **Mansion Management (マンション管理)** screen for the eo broadband residential service contract flow. Its primary business responsibility is to compose the full set of **mail text (メール文言)** — i.e., customer-facing informational messages — for mansion-managed properties, covering installation periods, optional security services, number portability notices, and construction content disclaimers.

The method supports multiple **service types** based on which services the customer has selected for the mansion property: **Net (Network/Internet)**, **TV**, and **Tel (Telephone)**. It also handles **service categories** such as eo Security Pack, Internet Security Gateway, Notification Premium, and indoor equipment supplementary services (PC plan / PC Wireless plan / TV plan).

It implements the **Builder design pattern** by initializing an empty `StringBuilder` and sequentially appending localized message fragments via `JFUWebCommon.getDispText()`, which resolves display keys against a message management table. Conditional branches route the message assembly based on **delivery method patterns** (Isa / Gigaisa, VDSL, direct fiber, light distribution), **installation status flags** (with construction / without construction), **contract start dates**, and **service selection states**.

The method is called by `finMskm()` within the same class, serving as a **shared presentation-layer utility** that generates the message payload for the mansion management confirmation screen. It does not perform any database CRUD operations itself — all data sourcing is delegated to bean accessors (`getKeiyakusvcinfo`, `getEonet`, `getEotel`, `getMansioninfo`) and common utility methods.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `webNewInfoBean` | `X31SDataBeanAccess` | The web form data bean carrying the customer's current input during the mansion management screen. Contains submission category (MSKM_KBN), selected services (Net/TV/Tel), contract service info, network info, telephone info, and mansion property details (delivery method, installation flag, 1G-only flag). |

**Instance fields / external state read:**
- `this` (the `FUW00943SFLogic` instance) — passed as context to `JFUWebCommon.getOpeDate(this, null)`.

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `getKeiyakusvcinfo(webNewInfoBean)` | - | - | Reads contract service information from web bean data |
| R | `getEonet(webNewInfoBean)` | - | - | Reads network service information from web bean data |
| R | `getEotel(webNewInfoBean)` | - | - | Reads telephone service information array from web bean data |
| R | `getMansioninfo(webNewInfoBean)` | - | - | Reads mansion property information from web bean data |
| R | `JFUStrConst.getDispText` | - | - | Resolves localized message text from message management table using display key |
| R | `JFUStrConst.getDispItem` | - | - | Resolves display item text for static UI labels (e.g., CX start date) |
| R | `JFUWebCommon.getDispText` | - | - | Resolves localized message text for the FUW00943 screen |
| R | `JFUWebCommon.getDispItem` | - | - | Resolves display item for CX start date configuration |
| R | `JFUWebCommon.getOpeDate` | - | - | Retrieves current operation date from the system |
| R | `JFUWebCommon.isHikariConcent` | - | - | Determines if the mansion property has a dedicated Hikari (fiber) concentration setup |
| R | `X31SDataBeanAccess.sendMessageString` | - | - | Extracts string values from data bean by message key |
| R | `JFUStrConst.isNull` | - | - | Null-check utility for strings |
| - | `JFUStrConst.RETURN_CODE` | - | - | Literal string constant used as newline separator for message assembly |

**Note:** This method performs **no database operations** itself. All data is sourced from the `X31SDataBeanAccess` web bean (which was populated by prior screen steps or DAO calls). The `getDispText`/`getDispItem` calls resolve display labels from a message management table (internal dictionary), and `getOpeDate` fetches the current operational date.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `FUW00943SFLogic.finMskm()` | `finMskm()` → `selectMansionMngn(webNewInfoBean)` | `getDispText [R]`, `getOpeDate [R]`, `sendMessageString [R]` |

**No screen/batch entry points** were found within 8 hops of this method. The only direct caller is `finMskm()`, which is a method within the same class (`FUW00943SFLogic`). This method is a **presentation-layer message assembler** — it does not trigger any business logic, data reads, or database operations.

**Terminal operations from this method:**
- `getDispText` [R] — Message lookup (repeated across many display keys)
- `getDispItem` [R] — Static display item lookup
- `getOpeDate` [R] — Current date retrieval
- `isHikariConcent` [R] — Fiber concentration check
- `sendMessageString` [R] — Web bean value extraction
