MatchResp ora include diag dict (CC feature). UI rendering:
- Nuovo pannello pieghevole "🔍 Diagnostica" sotto i tempi
- Per ogni match mostra:
* pipeline pruning (vars total → top_eval → top_pass → full_eval)
* candidati (raw → pre_nms → final)
* drop reasons (NCC, score, recall, bbox, NMS) con counter
* soglie effettive applicate
* flag attivi (polarity, soft, subpix-LM)
- Quando 0 match → pannello si apre automaticamente + mostra hint
contestuale specifico:
* "0 candidati top" → suggerisce ↓ min_score / top_thresh
* "tutti dropped da NCC" → ↓ verify_threshold (filtro_fp)
* "score post-NCC sotto" → ↓ min_score
* "recall basso" → ↓ min_recall
* "bbox out-of-scene" → check pose / search_roi
Risolve il pattern "0 match perche'?" con guida actionable invece
del black-box. Tutti e 3 endpoint match (/match, /match_simple,
/match_recipe) propagano il diag.
