DATETIME2(3) + cursor roundtrip via O format perdía sub-ms de
DateTime.UtcNow causando ~37% flake rate. Timestamp fijo con sub-ms=0
elimina la ambigüedad.
Fixes residual flake del issue #29.
6 clases que instanciaban Respawner directamente migran a recibir SqlTestFixture
vía ICollectionFixture. 8 clases restantes solo actualizan ConnectionString a
TestConnectionStrings.AppTestDb. Cada clase ahora es responsable únicamente de
sus seeds específicos; la limpieza de la base queda centralizada en el fixture.
Fix all test compilation errors caused by T400.10/T400.20/T400.30:
- Handler constructors: add TimeProvider.System as last argument
- Domain mutator calls: add DateTime.UtcNow as explicit 'now' argument
- AuditLogger/SecurityEventLogger Build() helpers: add TimeProvider.System
- JwtService test constructors: add TimeProvider.System
Cat2 coverage already present in TimeProviderArgentinaExtensionsTests.cs:
FakeTimeProvider proves GetArgentinaToday() returns ART civil date, not UTC.
Agrega Quartz.Extensions.Hosting 3.13.1 al catálogo central.
SIGCM2.Infrastructure/Audit/Jobs/:
- AuditPartitionManagerJob — mensual (cron '0 0 2 1 * ?', UTC). Extiende
pf_AuditEvent_Monthly y pf_SecurityEvent_Monthly con SPLIT RANGE para el
mes+2 (mantiene +1 de buffer). Idempotente: verifica existencia antes.
- AuditRetentionEnforcerJob — anual (cron '0 0 3 1 1 ?', UTC). DELETE rows
> 10 años en AuditEvent y > 5 años en SecurityEvent. Temporal history se
purga solo vía HISTORY_RETENTION_PERIOD del engine.
- AuditIntegrityCheckJob — semanal domingos (cron '0 0 1 ? * SUN', UTC).
Valida SYSTEM_VERSIONING=ON + partitions próximos 3 meses. Emite
SecurityEvent 'system.integrity_alert' failure via ISecurityEventLogger
cuando detecta inconsistencias.
AuditMaintenanceRegistration.cs:
- services.AddAuditMaintenance(configuration) wraps AddQuartz + AddQuartzHostedService
con los 3 triggers crónicos.
Program.cs:
- builder.Services.AddAuditMaintenance(configuration) wired ONLY en entornos
productivos — skipeado en 'Testing' para que los integration tests no
disparen los triggers cron durante el ciclo de vida del TestWebAppFactory.
Row-based DELETE en RetentionEnforcerJob es la opción conservadora para la
primera generación — cuando los volúmenes lo justifiquen (>200M filas), se
upgradea a SWITCH OUT + DROP para partition-level drop. Documentado en
comentario de la clase.
Tests (Strict TDD, integration):
- AuditJobsTests (3): PartitionManager crea target boundary + idempotencia,
RetentionEnforcer purga > threshold (10y audit, 5y security), IntegrityCheck
all-OK no emite alert.

Refs: sdd/udt-010-auditoria-trazabilidad/{spec#REQ-AUD-6 #REQ-SEC-5, design, tasks#B11}
Composes the audit emission layer per design #D-8:
SIGCM2.Infrastructure/Audit/AuditLogger.cs (IAuditLogger):
- Enriches from IAuditContext (ActorUserId/ActorRoleId/Ip/UserAgent/CorrelationId).
- Sanitizes metadata via JsonSanitizer + AuditOptions.SanitizedKeys.
- Persists via IAuditEventRepository.InsertAsync.
- Fail-closed: throws AuditContextMissingException when ActorUserId is null.
- Translates Guid.Empty correlation id to null (DB column is nullable; Empty
indicates 'no middleware ran').
- Uses System.DateTime.UtcNow for occurredAt.
SIGCM2.Infrastructure/Audit/SecurityEventLogger.cs (ISecurityEventLogger):
- NOT fail-closed: null ActorUserId is valid (login failures, anonymous
permission.denied events).
- Ip/UserAgent pulled from IAuditContext; metadata sanitized the same way.
- Persists via ISecurityEventRepository.
DI: AddScoped for both loggers in AddInfrastructure.
Tests (Strict TDD, mocks for IAuditContext/IAuditEventRepository/
ISecurityEventRepository):
- AuditLoggerTests (6): happy path with full context, fail-closed null actor,
metadata sanitization, null metadata pass-through, repo-throws-bubbles-up
(critical for TransactionScope rollback), custom SanitizedKeys from options.
- SecurityEventLoggerTests (4): login.success with context, login.failure
with null actor + attemptedUsername, metadata sanitization,
permission.denied with both actor and attemptedUsername null.
Two initial failures were fixed by replacing 'null' literal arguments in
NSubstitute Received(...) assertions with Arg.Is<T?>(x => x == null) —
NSubstitute does not always match null literals when mixed with Arg.Any<T>().

Introduces persistence layer for audit and security events per design #D-6:
SIGCM2.Application/Audit/:
- IAuditEventRepository: InsertAsync + QueryAsync with cursor pagination
- ISecurityEventRepository: InsertAsync only (no query — SecurityEvent is
queried only from an admin dashboard deferred to ADM-004)
- AuditEventQueryResult: (Items, NextCursor) record
SIGCM2.Infrastructure/Audit/:
- AuditEventCursor (public): base64(OccurredAt:O|Id) opaque cursor for
DESC pagination. TryDecode is fail-open — malformed cursor returns null
and the query starts from the top.
- AuditEventRepository: Dapper INSERT via OUTPUT INSERTED.Id + dynamic
WHERE composition with parameterized filters (zero SQL injection risk).
LEFT JOIN to dbo.Usuario to populate ActorUsername in AuditEventDto.
Pagination fetches Limit+1 rows to detect "more pages"; emits cursor
from the Nth row when overflow observed.
- SecurityEventRepository: straight INSERT for login/logout/refresh/
permission.denied events.
DI: AddScoped for both repos in AddInfrastructure.
Integration tests (Strict TDD): 13 total, all against SIGCM2_Test.
- AuditEventRepositoryTests (10): insert-roundtrip, filter-by-actor,
filter-by-target, filter-by-date-range, cursor pagination across 3 pages
(no overlap/no gap), malformed-cursor fail-open, LEFT JOIN Usuario
populates username, cursor encode/decode roundtrip, cursor malformed
variants.
- SecurityEventRepositoryTests (3): insert success, insert failure with
null ActorUserId + AttemptedUsername, CK_SecurityEvent_Result rejection.

Wires the request-scoped audit context per design #D-2:
Middleware pipeline in Program.cs:
app.UseCors()
app.UseMiddleware<CorrelationIdMiddleware>() // PRE-AUTH
app.UseAuthentication()
app.UseMiddleware<AuditActorMiddleware>() // POST-AUTH
app.UseAuthorization()
app.MapControllers()
SIGCM2.Api/Middleware/CorrelationIdMiddleware.cs:
- Preserves client-sent X-Correlation-Id header when a valid GUID, otherwise
generates Guid.NewGuid(). Stores in HttpContext.Items (audit:correlationId).
- Captures Ip (Connection.RemoteIpAddress) + UserAgent header into Items.
- Echoes the correlation id back via response header (OnStarting + immediate
set — immediate set makes unit testing against DefaultHttpContext reliable).
SIGCM2.Api/Middleware/AuditActorMiddleware.cs:
- Reads JWT 'sub' claim from authenticated HttpContext.User, parses to int,
stores as audit:actorUserId. Anonymous / non-numeric sub leaves it unset.
SIGCM2.Infrastructure/Audit/AuditContext.cs (IAuditContext scoped impl):
- Reads Items entries via IHttpContextAccessor. Returns null / Guid.Empty
when no HttpContext is available (jobs, tests without middleware).
- ActorRoleId intentionally null for now — rol code → id resolution is
deferred; the logger may resolve it at persist time in a later batch.
DI registration (Infrastructure/DependencyInjection.cs):
- services.AddScoped<IAuditContext, AuditContext>()
Tests (Strict TDD):
- CorrelationIdMiddlewareTests (6): generates/preserves/handles-malformed
correlation id, sets response header, captures ip/ua, calls next.
- AuditActorMiddlewareTests (5): authenticated/anonymous/no-sub/non-numeric/
calls-next.
- AuditContextTests (7): reads from Items, null-http-context defaults,
ActorRoleId currently null.

Adds the metadata sanitization layer per #REQ-AUD-5:
SIGCM2.Infrastructure/Audit/JsonSanitizer.cs (static class):
- Sanitize(object?, IReadOnlyCollection<string>) -> string?
- Serializes via System.Text.Json + JsonNode recursive traversal.
- Strips blacklisted keys at every nesting level (objects + arrays).
- Case-insensitive match (ToLowerInvariant on both sides).
- Null input -> null output (never throws).
- Output is always valid JSON (ISJSON=1 compatible — satisfies AuditEvent CHECK).
SIGCM2.Application/Audit/AuditOptions.cs:
- Documented the IConfiguration array-binding quirk: config is ADDITIVE
(append at higher indices), not REPLACE. Intentional for security — defaults
like 'password'/'token'/'cvv' must not be silently dropped.
SIGCM2.Infrastructure/DependencyInjection.cs:
- services.Configure<AuditOptions>(configuration.GetSection(AuditOptions.SectionName))
wired in AddInfrastructure().
Tests (Strict TDD, RED -> GREEN):
- JsonSanitizerTests (10): null/empty-blacklist/flat/nested/arrays/case-insensitive/
primitives/round-trip-valid-json/string-as-value/default-keys-effective.
- AuditOptionsBindingTests (2): defaults when section absent + additive override.
One test needed adjustment during GREEN: 'AlreadySerializedJsonString' originally
asserted against an encoding-specific literal; rewrote to use JsonDocument
round-trip (validates behavior without coupling to encoder quirks).
