-- V010__audit_infrastructure.sql
-- UDT-010: Infraestructura de Auditoría y Trazabilidad (Fase 0.5 — transversal).
--
-- Cambios:
--   1. Filegroups AUDIT_HOT y AUDIT_COLD (archivos físicos en default data path).
--   2. Partition functions + schemes mensuales (RANGE RIGHT) para AuditEvent y SecurityEvent.
--   3. dbo.AuditEvent particionada + 4 índices + CHECK constraints.
--   4. dbo.SecurityEvent particionada + 3 índices + CHECK constraints.
--   5. SYSTEM_VERSIONING en dbo.Usuario, dbo.Rol, dbo.Permiso, dbo.RolPermiso
--      con HISTORY_RETENTION_PERIOD = 10 YEARS y PAGE compression en history tables.
--
-- Source of truth del diseño: Obsidian/02-ARQUITECTURA-y-TECH-STACK/2.5 📋 Auditoría.md
-- Idempotente: seguro para re-ejecutar.
-- Reversa: V010_ROLLBACK.sql (pierde TODA la historia auditada).
-- Run on: SIGCM2 (dev) y SIGCM2_Test (integration tests). Para producción futuro,
-- revisar database/README.md (ventana de mantenimiento + backup previo).
