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.
Suite: 355/355 Application.Tests + 141/141 Api.Tests = 496/496 passing.
