-**Status:** **IMPLEMENTATO 2026-05-11.** Task 1-5 completati e mergiati su main. Task 6 (cost attribution per call_kind) **deferito** — i cost mutator finiscono già in `cost_records` con l'`agent_id` del parent, quindi il totale è contabilizzato anche senza breakdown per call kind.
+**Status:** **TUTTI I 6 TASK COMPLETATI** (task 1-5 il 2026-05-11, task 6 il 2026-05-12). Mergiati su main. Validato empiricamente: run `phase2-5-qwen25-prompt-mut-004` ha raggiunto max fitness **0.1012** (+225% vs baseline `phase2-qwen25-control-001` 0.0311). Sweet spot weight=0.30 (curva U: weight=0.50 → regressione plateau 0.0311; weight=0.00 → baseline piatto).
 
 **Trigger Phase 2.5 verificati con esito Phase 2 + run controllo:**
 - ✅ Plateau max fitness ≥ 4 gen consecutive (Phase 2 qwen3-235b stuck 8 gen a 0.0238; run controllo qwen-2.5-72b stuck 9 gen a 0.0311).
