Suggestion pointer acceptance transaction: press stores the next query epoch rather than its rendered epoch · case 02

The press-epoch completion transition produces an incorrect observable state.

Case contract

Pointer acceptance captures option identity on press; release must match the captured pointer and row, remain inside, and exceed neither drag slop nor query epoch. Blur defers while a valid option press is pending. Hover is only preview and never a value commit.

Why this case matters

Autocomplete couples draft text, suggestion identity and asynchronous presentation; this bounded lifecycle model isolates one observable interaction defect.
