Undoable autocomplete acceptance: redo restores the pre-completion caret position · case 03

The redo-caret completion transition produces an incorrect observable state.

Case contract

A completion acceptance is one undo transaction containing draft, committed identity and caret. Undo restores the pre-accept snapshot; redo restores the accepted snapshot. A subsequent edit discards redo, transient hover never enters the stack, and history snapshots own their data.

Why this case matters

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