Unavailable suggestion presentation: explicit unavailable suggestion acceptance submits its identifier · case 03

The commit completion transition produces an incorrect observable state.

Member previewVariant 3 · 3 implementations · 22 checks per implementation

Case contract

Unavailable options remain visible with reasons but cannot be committed or auto-selected. Availability is attached to identity, not display text. A committed unavailable value remains represented for correction. Disabled-only responses are distinct from empty results.

Why this case matters

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