+backend/api/agent_checkpoint.py — Simplified checkpoint endpoints (ARCH-K2.3)
+
+Aggiunge alias /api/agent/checkpoint (senza task_id nella path) per uso diretto dal frontend:
+  GET    /api/agent/checkpoint             — lista tutti i checkpoint attivi in memoria
+  POST   /api/agent/checkpoint             — salva checkpoint (taskId opzionale nel body)
+  GET    /api/agent/checkpoint/{task_id}   — recupera checkpoint specifico
+  DELETE /api/agent/checkpoint/{task_id}   — elimina checkpoint
+
+I checkpoint per-task esistono già su /api/agent/tasks/{id}/checkpoint (agent.py).
+Questi alias sono più comodi quando il frontend non ha un task_id esplicito
+(es. salvataggio periodico dello stato dell'agente, resume dopo refresh).
+
+ROUTING CF PAGES: /api/agent/* → HANDS (Space B) via HANDS_PATTERNS[0].
+Nessuna modifica a [[catchall]].ts necessaria.
+
+NOTA: Import da api.agent e api.persistence sono LAZY (dentro le funzioni)
+per evitare import circolari — agent.py importa già molti altri moduli.

-backend/api/memory_router.py — Memory Router unificato (ARCH-K2.3)
+backend/api/memory_router.py — Unified Memory Router (ARCH-K2.3)
 
-Implementa una MemoryAPI unificata che astrae i layer di memoria del Brain.
-Il Brain usa MemoryRouter invece di accedere direttamente a MemoryManager,
-rispettando l'invariante S9 (ogni servizio ignora l'impl interna degli altri).
+Espone /api/memory come interfaccia unica per tutti i layer di memoria:
+  GET  /api/memory         — lista/ricerca voci (layer, query, limit)
+  POST /api/memory         — scrivi voce (layer, key, value/content)
+  GET  /api/memory/stats   — statistiche aggregate tutti i layer
 
-Routing:
-  working   → memoria contestuale a breve termine (STM)
-  episodic  → episodi persistiti (LTM eventi)
-  semantic  → ricerca vettoriale (Knowledge)
-  all       → tutti i layer in parallelo
+Layer agent: persistito su Supabase (agent_memory) con fallback in-memory.
+Layer episodic/semantic/reflection: delegati a MemoryManager se disponibile.
 
-Interfaccia compatibile con MemoryManager per drop-in replacement:
-  memory_router.get_context(goal)       → str
-  memory_router.save_episode(...)       → None
-  memory_router.search(query, limit)    → list[dict]
-  memory_router.reflection.record_success(...)
+ROUTING CF PAGES: /api/memory (non /api/memory/compress o /semantic) → BRAIN
+Nessuna modifica a [[catchall]].ts necessaria.
 
-HTTP Endpoints (auth: MACHINE):
-  GET  /api/memory/router/status        — stato + configurazione
-
-Invarianti ADR: S4, S9, S21, S27
+NOTA: percorsi /api/memory/agent e /api/memory/decision già gestiti da _mem_router
+e _decision_router. Questo router aggiunge SOLO /api/memory (radice) e /api/memory/stats.

 """
 backend/api/policy.py — Policy Engine (ARCH-K2.4)
 
-Punto unico di controllo per ogni azione del Brain/Executor.
-Il Brain NON implementa mai direttamente auth, budget, retry o quota.
-Usa SOLO: from api.policy import policy; decision = await policy.check(ctx)
-
-Funzioni principali:
-  policy.check(PolicyContext)        → PolicyDecision (allow/deny/throttle)
-  policy.record_usage(task_id, ...) → None  (aggiorna contatori budget)
-  policy.get_session_budget(sid)    → BudgetStatus
-
-HTTP Endpoints (auth: MACHINE):
-  POST /api/policy/check             — check sincrono da servizi esterni
-  GET  /api/policy/status            — stato engine + configurazione
-  GET  /api/policy/budget/{session}  — budget residuo sessione
-
-Invarianti ADR:
-  S4:  Brain non conosce l'infrastruttura di policy
-  S9:  ogni servizio ignora l'implementazione interna degli altri
-  S15: ogni azione autorizzata prima dell'esecuzione
-  S16: retry con backoff esponenziale centralizzato
-  S17: quota e rate-limit applicati a livello Kernel
-  S21: Brain dipende solo dal Kernel (che chiama Policy)
-  S27: ogni decisione tracciabile via correlation_id
+Gestisce centralmente Authorization, Budget, Quota, Sandbox, Retry e Timeout
+per ogni tool call / task submission. Il Kernel (ARCH-K2.1) consulta questo
+modulo prima di eseguire qualsiasi operazione.
+
+Endpoints (auth: MACHINE):
+  GET  /api/policy/rules         — lista regole policy per risk level
+  GET  /api/policy/budget        — stato budget provider (reale, da memoria)
+  POST /api/policy/budget/record — registra utilizzo provider (chiamato dal loop LLM)
+  POST /api/policy/check         — valuta se un tool/task è autorizzato
+  GET  /api/policy/quota/{sid}   — stato quota per sessione
+  POST /api/policy/quota/reset   — reset quota sessione (OPERATOR)
+
+Invarianti rispettate:
+  - Budget check fail-open: se Supabase non risponde, non blocca (log warning)
+  - Quota sliding window: 60s — senza stato persistente non bloccante
+  - Timeout per risk level: safe=30s, medium=90s, risky=180s, dangerous=300s
+  - Retry per risk level: safe=3, medium=2, risky=1, dangerous=0
+  - Tool "dangerous" richiede sempre conferma esplicita (caller_confirmed=True)
