Stratara.Contracts

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

Wire-level POCO contracts shared by every Stratara package. Pure data records — no runtime, no DI, no infrastructure deps. Safe to reference from any layer.

Contents

  • Messages/EventMessage, EventBundle, CommandEnvelope — the cross-process envelope shapes that messaging adapters (Stratara.Outbox.RabbitMQ etc.) serialise on and off the bus.
  • Requests/PagedRequest — shared pagination + sort record used by query handlers across the family.
  • Session/SessionContext — public data shape for actor/subject identity, correlation, causation, and connection routing. The corresponding service abstractions live in Stratara.Sessions.

Quick reference

// Build a CommandEnvelope outside the framework (rare, but supported)
var envelope = new CommandEnvelope(
    Id: Guid.CreateVersion7(),
    CommandJson: commandJson,
    CommandTypeName: typeof(MyCommand).AssemblyQualifiedName!,
    SessionContextJson: sessionContextJson);

Stratara.Abstractions

Contract interfaces and POCO records for the Stratara CQRS / Event Sourcing framework — Mediator, EventSourcing, Persistence, Outbox, Messaging, Session, Security, Authorization. Library-safe, no EF Core or message-bus runtime.

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 command flows, domain-event helpers, merge primitives, and the Tier-A/B abstractions surface re-exported as one transitive bundle.

Stratara.Projections

Projection runtime for the Stratara event-sourced stack — projection-handler discovery, change-set creation, update application, and projection manager. Sits between read-model repositories and the event-bundle dispatcher.

Stratara.Outbox.RabbitMQ

Outbox-pattern command and event dispatch for the Stratara event-sourced stack — RabbitMQ IMessageBus implementation, retry worker, mediator command worker, and Redis-coordinated projection-replay state. Azure Service Bus support ships as the sibling Stratara.Outbox.AzureServiceBus package.

### 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.
