Stratara.Diagnostics

License: FSL-1.1-MIT (Functional Source License — source-available; converts to MIT after 2 years). Not OSI-approved OSS.

Generic observability primitives shared by all Stratara packages. Use this to emit Activity / Meter instruments under a uniform source name and stable event-ID schema.

Contents

  • ApplicationDiagnostics — ActivitySource("Stratara.Application") + Meter("Stratara.Service") + tag-name constants (correlation.id, causation.id, tenant.id, user.id) + metric names (event_source.append.conflicts). These names are part of the public observability contract — renaming them breaks downstream Grafana/Tempo queries.
  • LogEvents — [LoggerMessage] event-ID ranges per domain (ChangeSet=100_000s, BackgroundTasks=101_000s, EventStore=102_000s, …, Messaging=108_000s, Update=109_000s, Saga=110_000s). Even hundreds = info/debug, _1xx = error.
  • LoggerScopeExtensions.BeginCreateAggregateScope / BeginUpdateAggregateScope — pre-baked logging scopes for the create/update aggregate flows.

Quick reference

using var activity = ApplicationDiagnostics.Activity.Source
    .StartActivity("CreateOrder");
activity?.SetTag(ApplicationDiagnostics.TagNames.TenantId, tenantId);

ApplicationDiagnostics.Metrics.EventSourceAppendConflicts.Add(1,
    new("aggregate.type", "Order"));

Package Downloads
Stratara.Sessions

ASP.NET Core middleware and provider for Stratara's Actor/Subject session model. Reads tenant and user from JWT claims (or X-Tenant-Id / X-Client-Id headers) and populates the ambient ISessionContextProvider for every request.
Stratara.Shared

Umbrella package for the Stratara framework — source-generated logger extensions for outbox / saga / projection / messaging, domain-event helpers, merge primitives, and the Tier-A/B abstractions surface re-exported as one transitive bundle.
Stratara.Security

Dependency-light key-store and envelope encryption for the Stratara framework. Production IKeyStore implementation (EnvelopeFileKeyStore) with KEK-wrapped, versioned per-scope DEKs (rotation + revoke + crypto-shred), a file-backed master-key provider, and an AES-GCM blob encryptor with purpose-bound associated data. References only Stratara.Abstractions + BCL crypto — no EF Core, RabbitMQ, Redis, or cloud SDKs.
Stratara.Validation

Vendor-neutral request validation for the Stratara framework — a mediator pipeline behavior that runs IValidator<T> implementations before the handler and throws an aggregated StrataraValidationException on failure. No FluentValidation dependency; an optional adapter is shipped separately.

### Added

- **New package `Stratara.Testing`** — test doubles and assertion helpers so consumers can
 unit-test Stratara-based code without Postgres or RabbitMQ testcontainers. Reference it from
 test projects only.
 - `AggregateTestHarness<T>` + `Aggregate.Rehydrate<T>(...)` — given/when/then rehydration of an
   aggregate from events using the same reflection-based `Apply(...)` dispatch as the production
   aggregation service. It throws on an event with no matching `Apply` overload so a forgotten or
   mistyped overload fails the test; opt back into the production-lenient skip with
   `IgnoringUnmappedEvents()`.
 - `InMemoryKeyStore` — an `IKeyStore` that mints random 256-bit DEKs per `KeyScope` and supports
   rotation / revocation / scope-erasure without a master KEK or key file.
 - `TestBlobEncryptor.CreateAesGcm()` — the real AES-GCM `ISecureBlobEncryptor` over an
   `InMemoryKeyStore`, so blob round-trips exercise production encryption.
 - `InMemoryMessageBus` — an `IMessageBus` with synchronous in-process dispatch and a `Published`
   list for assertions.
 - `TestSessionContext` / `TestSessionContextProvider` — preset Actor/Subject `SessionContext`
   values and an `ISessionContextProvider` double.
 - `TestTenants.Of("acme")` — stable, deterministic tenant/user ids from readable slugs.
   `TestSessionContext` sets both correlation and causation ids so the context can drive
   event-store writes.
 - `TestEvent.Create(payload, ...)` — wrap an event payload in `IEvent<T>` with realistic
   metadata; `ProjectionTester.HandleAsync(projection, event)` — invoke a projection's private
   `HandleAsync` handler directly to unit-test it against mocked repositories.
- **New package `Stratara.Testing.EntityFrameworkCore`** — spins up the **real** event-sourcing
 write stack (`IEventSource`, `IAggregationService`, snapshots, the EF Core write store) against a
 shared in-memory SQLite database in one call, so tests exercise production code paths without
 Postgres or Docker. Reference it from test projects only.
 - `EventStoreTestHost.Create(...)` — owns the SQLite connection + service provider; exposes
   `ExecuteAsync(IEventSource)`, `AggregateAsync<T>(streamId)`, the preset `Session`, and the
   recording `Outbox`.
 - `AddStrataraTestingEventStore<TWriteDbContext>(connection, tenantId)` — the lower-level DI
   extension; `StrataraTestWriteDbContext` — a ready-made concrete write context;
   `RecordingEventBundleOutboxDispatcher` — captures emitted bundles for assertions.
 - The lockstep family grows from 22 to 24 packable packages.
