FA-23133 / Autocomplete interactions / Member archive

Autocomplete query activation policy: zero-character browse uses the minimum-length prompt instead of recent choices · case 03

The empty-query-mode completion transition produces an incorrect observable state.

Member previewVariant 3 · 3 implementations · 22 checks per implementation

Case contract

This stipulated picker searches only after minimum draft length unless explicit browse is requested. Empty-query browse uses recent suggestions, composition blocks query emission, and disabled/read-only interaction suppresses new requests. Draft erasure cancels pending search and clears query-bound results.

Why this case matters

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