1. Post-Bind Manual Re-Login

• 1.1 Route mandatory bind success to pages/login/login instead of continuing directly to pages/index/index
• 1.2 Show a one-time prompt that the user needs to log in again after successful binding
• 1.3 Preserve the previously entered identifier so the login input stays prefilled after returning
• 1.4 Ensure the restored identifier does not auto-trigger login and the user must manually tap login

2. Flow Compatibility

• 2.1 Keep the existing non-mandatory bind completion behavior unchanged
• 2.2 Remove dependence on automatic post-bind wechat-login continuation
• 2.3 Keep the normal homepage bind gate behavior for later homepage entries
• 2.4 Remove dependence on a one-time homepage bypass for mandatory bind success

3. API Contract Preservation

• 3.1 Keep using the existing login and bind-phone API contracts
• 3.2 Avoid adding a backend endpoint or changing current response schemas

4. Regression Verification

• 4.1 Verify mandatory bind success returns to the login page with the identifier still visible
• 4.2 Verify the login page shows the re-login prompt after bind success
• 4.3 Verify login does not auto-start until the user clicks login
• 4.4 Verify ordinary bind entry from homepage actions still follows the current completion path
