## 1. Role

### JKKOpsvkeiTelIktAddCC.mainProc()

This method is the **central orchestration routine for the K-Opticom telephone service one-stop registration** (電話サービス一括登録), a core telecom order fulfillment workflow. It handles the complete lifecycle of registering a new **Option Service Contract (Telephone)** (オプションサービス契約〈電話〉) including all its subordinate service details and sub-option services, coordinating with 17 distinct Service Components (SCs) to manage the service contract, service detail agreement, device provisioning, content acceptance, and activation processes.

The method implements a **routing/dispatch pattern**: it first validates the service contract hierarchy by calling agreement/confirmation SCs (EKK0081A010, EKK0161A010, EKK0341B002, EKK0251B003), then branches based on content acceptance status (`isShosazumi`) to conditionally execute registration and post-processing steps. Within its main processing loop (iterating over `jkkOpsvkeiTelIktAddCCList`), it applies a **multi-branch delegation pattern** to handle two service types — **Option Services** (メインオプションサービス) and **Sub-Option Services** (サブオプションサービス) — each with its own registration, billing notification, check-close, and activation flows.

The method also manages the **SOD (Service Order Data) issuance flag**, determining whether a service can trigger SOD issuance based on VLAN-ID fix status, device manufacturing number, and the service type (particularly the Tenso/Bundled service B024). Upon completion, it delegates the actual SOD issuance to `JKKHakkoSODCC.hakkoSOD()`.

**Branch Summaries:**

- **Pre-loop SC calls (Step 1–4)**: Always executed sequentially. Each SC call checks for non-zero `statusCode` and returns immediately on failure.
- **Content acceptance check (`isShosazumi(svcKeiStat)`)**: If the service contract status indicates pending content acceptance, the method registers the content acceptance (EKK0011D020) and requests the post-processing check (EKK0021C060).
- **Fallback multi-function router lookup (ANK-3754)**: If the device manufacturing number (`kikiSeizoNo`) is empty and the service line detail list is available, a fallback SC (EKK0341B504) searches for multi-function router records with service type `C024` (TakinoRort/Telecom) or `C025` (HGW/Home Gateway) having status below `910`.
- **SOD issuance flag**: Set to `true` when VLAN-ID is fixed (`vlanIdFixFlg == "1"`) AND a device manufacturing number exists.
- **Main loop — Option Service branch (`isSvcKei == true`)**: For each Option Service item, handles three sub-branches:
  - **Billing amount reach notification (B072)**: If the service code is `B072` (通話指定額到達通知 / Call Allowance Limit Reach Notification) and an option service contract number exists, calls EKK0371A010, compares DB vs. input billing amounts, and conditionally updates (EKK0371C050) or registers (EKK0371D010).
  - **Registration without billing notification**: Calls EKK0371D010, then follows the service detail status chain (Check Close → Check/Check Close → Start Activation).
  - **Sub-Option Service branch (`isSvcKei == false`)**: Same flow structure but uses Sub-Option SCs (EKK0431* series) and calls EKK0831A010 for the service agreement lookup instead of EKK0821A010.
