Ho ricostruito la causa root con 5-why chain:
1. Cascade lock → 2. SELECT FOR UPDATE senza index → 3. Migration mancante → 4. Pipeline continue-on-error → 5. Workaround 2024-11 mai rimosso (root cause).
PIR draft pronto. 5 corrective actions suggerite. Vedi RCA →

Rollback completato. Ambiente stabile. Procediamo con post-incident review domani 14:00.

Confermo: migration 0142_add_status_idx.sql non applicata in prod-eu-1. Drift da prod-us-1.

L'incident ha impatto business (€18k). Vale la pena valutare se NIS2 Det. ACN 379907/2025 richiede pre-notifica (24h) — soglia: "Incident significativo con impatto su servizio essenziale". Security Expert produce draft pre-notifica.

Quando attivo (Sprint S2), MCP Control può eseguire fix immediato: applicare la migration mancante via mcp-postgres + rimuovere continue-on-error dal pipeline via mcp-github. Sentinel Safety gate richiesto.
