The list button in an email is already a deliberate choice. Miracle now treats that click as the confirmation when the matching account is signed in.
- The email capability stays after the URL fragment marker, so link scanners never send it to Miracle during their automatic checks.
- The first server request remains read-only. A matching signed-in account applies the selected list once and lands on the exact result.
- A signed-out browser or prefetch stays read-only and shows the exact action before anything changes.
- Older receipt links are moved into the same protected fragment flow before their action page renders.
- Repeated clicks are idempotent. The first applied choice resolves the other list buttons from that receipt.
- Expired, completed, archived, deleted, and due-date-protected tasks remain unchanged and explain the next available action.
- Ordinary iPhone and browser failures render Miracle's private result page. Raw AMP transport JSON stays inside supported dynamic email clients and never becomes a browser error screen.
One email choice now produces one deterministic result without a redundant confirmation.
