## 1. Role

### KKW00121SFLogic.checkKKW00124Error()

This method performs comprehensive pre-registration validation for the eo Net service contract screen (KKW00124 / 照枠前登録 — "Before Confirmation Frame Registration"). It is the central validation gate invoked just before a customer's service contract data is submitted for processing. The method checks required-field completeness, cross-field consistency, tablet and smartphone terminal purchase validations, service pack (Security Pack, Family Pack, Premium Pack, Smart Premium) co-registration rules, router rental fee change detection, and Type-N-specific telephone number and transfer rules. It employs a routing/dispatch pattern by branching based on customer type (mansion vs. mezohn vs. Type-N), connection method (Ethernet, optical fiber, VDSL), and conditional flags (tablet purchase, IP-STB rental, course change). Its role in the larger system is that of a shared validation orchestrator called by multiple entry methods within `KKW00121SFLogic` — namely `checkAllGamenError()`, `checkGamenError()`, `smpAgntGet()`, and `tabletAgntGet()` — ensuring screen-level data integrity before any service component (SC) calls are made. The method supports three distinct service categories: Net service contracts, tablet device purchase flows, and streaming media player (SMP) purchase flows, with conditional branches handling each category's specific validation rules.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `isErrClear` | `boolean` | Controls whether to clear existing page error information before performing validation. When `true`, the method resets accumulated error info (`clearPageErrInfo`) and clears the network display status flag. This is used when re-entering the screen or re-triggering validation from a retry scenario. `true`: clear errors then check, `false`: skip clearing (used when errors should be accumulated across multiple checks). |
| 2 | `isCallTabletAgntGet` | `boolean` | Indicates whether this validation is being called from the `tabletAgntGet()` flow (tablet agent acquisition flow). When `true`, the tablet terminal buyer name validation is skipped because the buyer name has already been pre-filled by the tablet agent flow. `true`: called from tablet agent, `false`: standalone tablet purchase flow. |
| 3 | `isCallSmpAgntGet` | `boolean` | Indicates whether this validation is being called from the `smpAgntGet()` flow (streaming media player agent acquisition flow). When `true`, the SMP terminal buyer name validation is skipped because the buyer name has been pre-filled. Added in ANK-3987-00-00 (Netflix introduction support). `true`: called from SMP agent, `false`: standalone SMP purchase flow. |

**Instance fields / external state read:**

| `dataBean.sendMessageString()` calls | Various string values from screen state (review result, commitment item, terminal names, etc.) |
| `getMansionMap()` | Retrieves mansion-specific data from session |
