Suggestion identity reconciliation: duplicate result identifiers render duplicate suggestions · case 03

The dedupe completion transition produces an incorrect observable state.

Member previewVariant 3 · 3 implementations · 22 checks per implementation

Case contract

On a new result snapshot, option identifiers determine continuity; labels are presentation only. Duplicate identifiers collapse at their first occurrence. Active and selected identities survive only where specified, and a query replacement clears transient result state.

Why this case matters

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