Federated suggestion sections: empty local section causes the entire picker to show no results · case 02

The source-empty completion transition produces an incorrect observable state.

Case contract

Local-history and remote suggestions are separate ordered sections. Stable identity includes source namespace. Empty sections have no header; pending remote work does not hide completed local results. Section headers are display rows, never commit candidates.

Why this case matters

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