CONTRAINTE STRICTE -- Tables autorisees UNIQUEMENT :
- agencecom.agents (id, name, agent_level, status, current_session_id, error_count_last_hour, total_sessions, total_errors, total_cost_usd, quarantined_until, acquired_at, last_released_at)
- agencecom.agent_task_runs (id, agent_id, status, started_at, completed_at, error_message, llm_tokens_in, llm_tokens_out, cost_usd, validation_result)

Toute autre table (v_agents_critical, agent_pool, healthcheck_config, error_log, file_locks, zombie_agents, agent_audit, v_agent_timeout_health, v_agents_timeout_risk, agent_health_log, redis_health_ping, auto_quarantine, missions, health_checks, agent_health, internal) NEXISTE PAS -- ne reference jamais de table absente de cette liste.

Identifie les agents zombies (busy >1h sans completion via started_at + status), error_count_last_hour > 5, ou drift quarantine (quarantined_until > now).
Donne 3 recommandations concretes en markdown bullet points avec actions SQL utilisant SEULEMENT les 2 tables autorisees ci-dessus.

**Agents zombies (tâche busy > 1h sans completion)**  
```sql
SELECT a.id, a.name, a.status AS agent_status, r.id AS run_id, r.started_at
FROM agencecom.agents a
JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
WHERE r.status IN ('running', 'busy')
  AND r.completed_at IS NULL
  AND r.started_at < NOW() - INTERVAL '1 hour';
```

**Agents avec error_count_last_hour > 5**  
```sql
SELECT id, name, error_count_last_hour, status
FROM agencecom.agents
WHERE error_count_last_hour > 5;
```

**Agents en dérive de quarantaine (quarantined_until > now)**  
```sql
SELECT id, name, quarantined_until, status
FROM agencecom.agents
WHERE quarantined_until > NOW();
```

---

**Recommandations concrètes avec actions SQL (tables autorisées uniquement)**  

- **Libérer les zombies – stopper les tâches bloquées et remettre l’agent en idle**  
  ```sql
  -- Terminer les runs zombies
  UPDATE agencecom.agent_task_runs
  SET status = 'failed',
      completed_at = NOW(),
      error_message = 'Zombie timeout (>1h sans completion)'
  WHERE id IN (
    SELECT r.id
    FROM agencecom.agents a
    JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
    WHERE r.status IN ('running', 'busy')
      AND r.completed_at IS NULL
      AND r.started_at < NOW() - INTERVAL '1 hour'
  );

  -- Repasser les agents concernés en idle
  UPDATE agencecom.agents
  SET status = 'idle'
  WHERE id IN (
    SELECT DISTINCT a.id
    FROM agencecom.agents a
    JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
    WHERE r.status IN ('running', 'busy')
      AND r.completed_at IS NULL
      AND r.started_at < NOW() - INTERVAL '1 hour'
  );
  ```

- **Isoler les agents trop erratiques – mise en quarantaine automatique**  
  ```sql
  -- Quarantaine de 15 minutes pour tout agent dépassant le seuil d'erreurs
  UPDATE agencecom.agents
  SET status = 'quarantined',
      quarantined_until = NOW() + INTERVAL '15 minutes'
  WHERE error_count_last_hour > 5
    AND status != 'quarantined';  -- éviter les doubles quarantaines
  ```

- **Corriger la dérive de quarantaine – aligner le statut quand quarantined_until est dans le futur**  
  ```sql
  -- Si un agent a une date de fin de quarantaine future mais n'est pas marqué quarantined,
  -- on le force en quarantined pour rétablir la cohérence.
  UPDATE agencecom.agents
  SET status = 'quarantined'
  WHERE quarantined_until > NOW()
    AND status != 'quarantined';
  ```

> Ces trois actions utilisent exclusivement les tables `agencecom.agents` et `agencecom.agent_task_runs`, conformément à la contrainte.
