Stratara.Infrastructure
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
License: MIT.
Cross-cutting infrastructure plumbing for the Stratara framework — the Tier-C glue that lets downstream apps wire authorization, DI composition, and worker-stack configuration with a single reference.
Contents
- Authorization decorators over command-outbox dispatch (
AuthorizingCommandOutboxDispatcher) — enforces[RequireRole]and[RequirePermission]on the command's runtime type before it reaches the outbox. - DI composition helpers that wire Mediator, Outbox, Identity, and EFCore into a hosted app.
- Configuration providers and option binders used by the worker stack.
Dependencies
Transitively depends on Stratara.Contracts, Stratara.EventSourcing.EntityFrameworkCore, Stratara.Mediator, Stratara.Outbox.RabbitMQ, Stratara.Sessions, Stratara.Shared.
Behavioural notes
AddSecurity() — IKeyStore registration (since 3.0.11)
AddSecurity() registers Stratara's security stack including the IKeyStore abstraction. The default is a TryAddSingleton<IKeyStore, DummyKeyStore> fallback — but DummyKeyStore since 3.0.11 throws InvalidOperationException in any environment other than Development (whitelist guard to prevent production data exposure from the demo encryption key). Hosts on Staging, QA, UAT, Preview, or any custom environment must register a real IKeyStore implementation before calling AddSecurity():
// Recommended composition root
if (builder.Environment.IsDevelopment())
{
builder.Services.AddSecurity(); // DummyKeyStore fallback is fine
}
else
{
// The production key store Stratara ships (Stratara.Security): KEK-wrapped, versioned
// per-scope DEKs. Register it before AddSecurity() so it wins the TryAdd race.
builder.Services.AddStrataraFileKeyStore(builder.Configuration);
builder.Services.AddSecurity();
}
Stratara ships one production IKeyStore — EnvelopeFileKeyStore, via AddStrataraFileKeyStore.
There is no built-in Azure Key Vault / AWS KMS / HSM store; if you need one, implement IKeyStore
against your provider and register it in place of the file store.
KeyStoreStartupProbe logs a Warning (event id LogEvents.KeyManagement.DummyKeyStoreActive = 112_001) at host start when the resolved IKeyStore is DummyKeyStore — even in Development — so an accidental dependency on the dummy is loud rather than silent.
Why the change: Before 3.0.11 the guard only blocked IsProduction(). Hosts in any other environment silently encrypted with the world-known constant pass-phrase "StrataraTestKey" baked into the shipping NuGet — a Staging or QA copy of production data could be decrypted by anyone reading the source. The whitelist guard makes this configuration crash-fast at host build instead of allowing silent data exposure.
AddCaching() — Redis registration
AddCaching() used to delegate to builder.AddRedisClient("redis") from Aspire.StackExchange.Redis. After the Aspire-wrapper removal it registers IConnectionMultiplexer directly via ConnectionMultiplexer.Connect(...) from StackExchange.Redis. The method signature is unchanged, but the Aspire-only side-effects are gone:
- No automatic Redis health check. Add one explicitly with
AddHealthChecks().AddRedis(connectionString)(fromAspNetCore.HealthChecks.Redis) if your host exposes/healthand you want Redis covered. - No automatic OpenTelemetry Redis instrumentation. Add
OpenTelemetry.Instrumentation.StackExchangeRedisand.AddRedisInstrumentation()to yourTracerProviderBuilderif you want Redis spans in your traces.
The connection-string lookup (ConnectionStrings:redis in configuration) is identical to the pre-cleanup behaviour.

Stratara.EventSourcing.WorkerDefaults
Worker-host wiring composites for the Stratara event-sourced stack. IHostApplicationBuilder extensions (AddBackendServices, AddCommandWorkerServices, AddHeavyCommandWorkerServices, AddEventProjectionWorkerServices, AddEventStreamHashWorkerServices, AddSagaWorkerServices, AddOutboxWorkerServices) bundle the per-concern DI calls so each worker host opts in with one line. |
|
|
Stratara.Testing.EntityFrameworkCore
Spin up the real Stratara event-sourcing write stack (EventSource, aggregation, snapshots, the EF Core write store) against a shared in-memory SQLite database in one call — production code paths, no Postgres, no Docker. Builds on Stratara.Testing's in-memory doubles. |

Two operational fixes, both found while a consumer rolled out bus-envelope signing and reasoned
about rebuilding its read models: a projection replay now survives a passing failure, and an
integrity failure says whether the signature was absent or wrong. Additive on every published
surface.
### Added
- **A projection replay retries a failing batch before it gives up.** Each batch — the read from
the event store and the application of its entries — now runs under a new named policy,
`ResilienceNames.ProjectionReplayBatch`: five attempts in all, exponential backoff from one second
with jitter between them, any exception except cancellation. A read-store timeout or a
dropped connection mid-rebuild no longer ends the replay; a failure that persists through every
attempt ends it exactly as before, with the same failure record. A retried batch is applied
again from its first entry in a fresh scope, which relies on the guarantee projections already
give under at-least-once delivery: a second application converges (see *Write handlers that
converge rather than accumulate* in the projection guide). Each failed attempt logs a new
warning, `104_011`. `AddResiliencePipelines` registers six policies rather than five. Nothing
about truncation, ordering, progress, the failure record or the lease changes.
### Changed
- **An integrity failure now says whether the signature was absent or wrong, and the existing
warning and error ids fire only for a signature that is present and does not verify.** An
unsigned envelope — what every not-yet-restarted publisher emits during a `Permissive` roll —
was logged as *"signature mismatch"* under the same id as a key mismatch or tampering, so an
operator could not tell a rolling restart from an attack without correlating host start times.
Four new event ids carry the unsigned case: `105_004` (command, permissive), `111_004` (event
bundle, permissive), `105_105` (command, strict) and `111_105` (event bundle, strict). The
existing `105_003`, `111_003`, `105_104` and `111_104` keep their numbers and their level but
now mean a present signature that did not verify; an alert keyed on one of them goes quiet
during a roll instead of firing for every unsigned message. Strict-mode rejections name the
case in their exception message. `BusEnvelopeIntegrityVerifier.Verify` gains an overload with
`out BusEnvelopeIntegrityFailure` (`None`, `Absent`, `Invalid`); the existing overload and the
`BusEnvelopeIntegrityResult` values are unchanged. An absent signature no longer reaches the
signer, which already answered `false` for it.
