## 1. Role

### JFUDslNetOpSvcKeiCC.dslSbOpSvcKeiMlad()

This method performs the core **sub-optional service contract cancellation execution processing** for the **eo Hikari Net (eo光ネット)** internet service in Japan. Specifically, it handles the cancellation (解約, *kaiyaku*) of sub-optional service contracts associated with a DSL network operation. It is the "Mail Address" (メールアドレス) variant of the broader optional service cancellation flow — the counterpart `dslOpSvcKeiMlad()` delegates to this method after resolving pre-conditions and gathering input data.

The method implements a **filter-and-dispatch routing pattern** across each sub-optional service contract record. For each contract in the list, it first validates eligibility by checking the service code against `MLAD_DSL_SBOP` (only email address, Wi-Fi Check, and My Home Page cancellation targets are processed) and then filters out any contracts with invalid statuses from `SVC_KEI_STAT_MUKO` (canceled or terminated contracts are skipped).

For eligible contracts, the method branches by service contract status into two cancellation strategies:
- **Cancellation (キヤンセル) path** — When the contract status is `CD00037_020` ("approved", 照会済), meaning the cancellation request has been reviewed and approved. This triggers a single `EKK0401C150` SC call for contract cancellation.
- **Contract termination (解約) path** — When the contract is still active (not yet approved or already in service provision). This triggers a more complex sequence: a non-fee assessment via `jdgHiChrg()`, followed by contract cancellation via `EKK0401C170`, and finally cancellation confirmation via `EKK0401C180`.

After processing the cancellation, if the sub-optional service code is `CD00137_D01` (Email Address), the method performs an additional ISP agreement inquiry (`EKK0411A010`) and triggers email aging processing via `dslAging()`, which releases or invalidates email-related resources.

**Processing overview (constant resolution):**
- `MLAD_DSL_SBOP` = `[CD00137_D01, CD00137_D02, CD00137_D03]` — sub-optional service codes eligible for cancellation processing (see Glossary for descriptions)
- `SVC_KEI_STAT_MUKO` = `[CD00037_910, CD00037_920]` — invalid contract statuses to skip (see Glossary)
- `CD00037_020` = "Approved" (照会済) — indicates the contract cancellation request has been reviewed and approved
- `CD00137_D01` = "Email Address" — the email address service type, which triggers additional aging processing
