Stratara.Identity.Core 3.1.2

• net10.0

  • Stratara.Shared (>= 3.1.2)

### 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.
