-- NIS2 Agile — Migration 056: Riesame di Direzione (ISO 27001 §9.3)
-- ----------------------------------------------------------------------------
-- Modulo B del design docs/DESIGN_AUDIT_INTERNI_RIESAME_DIREZIONE.md.
-- Produce il VERBALE del riesame periodico del SGSI con INPUT aggregati dai
-- moduli esistenti (snapshot congelato all'approvazione) e OUTPUT = decisioni.
--
-- RUNNER-SAFE: SOLO CREATE TABLE IF NOT EXISTS con TUTTE le FK inline.
-- Niente ALTER ADD CONSTRAINT, niente DELIMITER o stored-proc, niente
-- separatori statement nei commenti. Idempotente (re-eseguibile). Charset utf8mb4.
-- Applicare con il seeder CLI application/cli/seed_management_reviews.php
-- (stessa connessione PDO dell'app — vedi nota mig.052/053).
