Autocomplete form binding: multi-value autocomplete joins identifiers into one ambiguous value · case 03

The many completion transition produces an incorrect observable state.

Case contract

Form submission serializes committed suggestion identifiers separately from visible draft text. Required checks apply to committed values, an empty-string identifier is present, disabled fields are omitted, and reset restores the initial identity and label together. Multi-value fields preserve separate values.

Why this case matters

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