Applied to SIGCM2 (dev) and SIGCM2_Test.
V010__audit_infrastructure.sql (idempotent, ~280 LoC):
- Filegroups AUDIT_HOT + AUDIT_COLD with physical files (per-DB logical names
via DB_NAME() prefix to avoid collision in dev/test).
- pf/ps_AuditEvent_Monthly + pf/ps_SecurityEvent_Monthly (RANGE RIGHT,
DATETIME2(3), 14 boundaries 2026-01..2027-02 → 15 partitions). Job extends
forward monthly in B11.
- dbo.AuditEvent (partitioned, clustered PK on OccurredAt+Id) + 4 indexes
(Actor/Target/Action/Correlation) with PAGE compression.
- dbo.SecurityEvent (partitioned) + 3 indexes (Actor/Action_Result/Ip_Failure).
- CHECK constraints: Action LIKE '%.%', ISJSON(Metadata), Result IN (success|failure).
- SYSTEM_VERSIONING ON in Usuario/Rol/Permiso/RolPermiso with 10 YEARS retention +
PAGE compression in history tables.
- No hard FK on ActorUserId → Usuario.Id (soft FK — audit must survive user deletion).
V010_ROLLBACK.sql: emergency reversal (WARNING: destroys all audit history).
database/README.md: migration order + V010 prod-apply notes.
tests/SIGCM2.TestSupport/SqlTestFixture.cs:
- EnsureV010SchemaAsync() validates audit infra is applied (fails fast with
clear message if not — migration itself requires ALTER DATABASE privileges
and is applied manually via sqlcmd).
- Respawn TablesToIgnore extended with *_History (engine rejects direct DELETE
on system-versioned history tables).
tests/SIGCM2.Api.Tests/Audit/V010MigrationTests.cs — 5 smoke tests:
- AuditEvent insert+roundtrip with CorrelationId.
- CK_AuditEvent_Action rejects Action without '.'.
- CK_AuditEvent_Metadata rejects non-JSON.
- CK_SecurityEvent_Result rejects invalid Result.
- Usuario SYSTEM_VERSIONING: temporal query FOR SYSTEM_TIME AS OF returns
pre-update state + Usuario_History populated.
Suite: 130/130 passing (previous 124 + spike B0 + 5 new B1). No regressions.

Validates design decision #D-1 (TransactionScope ambient over IUnitOfWork):
TransactionScope with TransactionScopeAsyncFlowOption.Enabled does NOT
escalate to MSDTC when multiple SqlConnections share the same connection
string. Test passes (DistributedIdentifier == Guid.Empty).
Unblocks UDT-010 batches B1-B14.
Refs: sdd/udt-010-auditoria-trazabilidad/{design,tasks}
Transaction-scoped tests conflicted with the repository opening its own connection,
blocking on FK locks for the uncommitted seeded user and causing timeouts.
Switched to the Respawn pattern used by UsuarioRepositoryTests ([Collection("Database")])
which commits seed data and resets between test classes.
