## MODIFIED Requirements

### Requirement: Bind completion SHALL remain compatible with homepage entry
The system SHALL keep ordinary bind-phone completion compatible with homepage entry while allowing mandatory bind-phone completion from the login gate to return to the login page for a manual re-login.

#### Scenario: User completes ordinary binding and returns to index
- **WHEN** the user completes phone binding successfully after entering the bind page from a later homepage action
- **THEN** the system SHALL return the user to `pages/index/index`
- **AND** entering `index` afterward SHALL no longer redirect if the account is now bound

#### Scenario: User completes mandatory binding and returns to login
- **WHEN** the user completes phone binding successfully after entering the bind page from the mandatory login gate
- **THEN** the system SHALL return the user to `pages/login/login`
- **AND** the system SHALL preserve the previously entered identifier for the login input
- **AND** the user SHALL manually trigger the next login attempt before the homepage-entry gate is evaluated again
