Federated suggestion sections: empty recent-suggestions section keeps a dead header · case 05

The local-header completion transition produces an incorrect observable state.

Member previewVariant 5 · 3 implementations · 22 checks per implementation

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.
