-- 046 — NIS2 framework: TABELLE DI CONFIGURAZIONE (Epic C / C1)
-- =====================================================================
-- Fonte dati AUTORITATIVA: docs/simon/C1_Misure_Requisiti.xlsx +
-- C1_Vista_MisureRequisiti.xlsx (codifica NON variabile per direttiva Simon).
-- Seed via application/data/nis2_framework_seed.json (import-only).
--
-- Natura: SYSTEM-LEVEL (nessun organization_id), CANONICHE, sola-lettura per
-- l'utente; configurabili solo da super_admin/sistema. Il runtime legge QUESTE
-- tabelle (data-driven), NON file hardcoded.
--
-- ADDITIVO e REVERSIBILE: DROP TABLE cfg_nis2_requisiti, cfg_nis2_misure,
-- cfg_nis2_procedure, cfg_nis2_rischi, cfg_nis2_ambiti;
-- Runner-safe: solo CREATE TABLE IF NOT EXISTS (no DELIMITER/stored-proc).
