Suggestion request context: token request collapses the replacement range to the caret · case 02

The range completion transition produces an incorrect observable state.

Case contract

A suggestion request is bound to draft, field identity, selection range, locale and dependency scope. Each outgoing descriptor carries those values from the initiating snapshot; accepting a response requires the same query epoch and field instance. No transport behavior is modeled.

Why this case matters

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