    checklist starts pre-selected with the recommended memories. With `allow_empty:true`
    an empty selection is accepted (no memory applied; deselected still recorded) and
    the phase advances — no separate gate.
+   When the memory search returned **zero** candidates, still issue the single
+   `reviewer_decide(multi:true, advance:true, allow_empty:true)` with an empty merito list: the gate
+   detects the empty+advance case, shows the reviewer an info notice ("Nessuna memory

+   an empty checklist, and you do NOT add a separate `reviewer_confirm kind:"phase"`.
 4. Closing: if memories were applied or rejected (substantive decisions), `advance:true`
    no-ops — close with `reviewer_confirm kind:"phase"`. Only a truly empty memory phase
    (nothing applied, nothing rejected) auto-advances via `advance:true`.
