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. |

Three correctness fixes, all of the same kind: behaviour that failed by succeeding. A pipeline
behaviour registered twice ran twice and nothing said so; a closed generic type name normalized to a
malformed key that two different types could share, and the loser of that collision was discarded
silently; and a heavy command republished from the outbox left its lane whenever its type could not
be resolved. None produced an error, and no test covered any of them. They were found by reading the
code against the specification rather than by a failure report.
### Fixed
- **A pipeline behaviour registered twice now installs once.** Every behaviour registrar used a
plain scoped registration, so a host that called one twice — the ordinary result of composing two
service bundles that each set up their own slice of the framework — installed the stage twice and
ran it twice per request. None of the three consequences was benign: every validator ran twice
against every request, so a validator with a side effect (a uniqueness check against the database)
performed it twice; the tenant guard ran twice, the second time against a second options instance
that could disagree with the first; and two nested resilience pipelines multiplied rather than
added, turning a configured budget of four attempts into sixteen. `AddStrataraValidation`,
`AddStrataraTenantIsolation`, `AddStrataraResilienceBehavior`, `AddCommandAuditing` and the
`AddPipelineBehavior` / `AddPipelineBehaviorWithResult` primitives are now idempotent per behaviour
type. Registering two *different* behaviours is unaffected.
- **A closed generic type name now normalizes correctly.** Resolving a recorded type name is meant to
ignore the assembly version and match on the type name and assembly name alone. For a closed
generic it did neither: the name was truncated at its second comma, which for a generic falls
*inside* the type-argument brackets, so the outer assembly name was dropped and the key became a
malformed fragment. Two closed generics that differed only in the assembly that declared them
collapsed onto one key, and the second registration was then silently discarded — an event
upcaster could match the wrong source type, and a type a host believed it had registered was
unresolvable. Names are now parsed rather than counted, and each type argument is reduced the same
way as the outer name, so upgrading the *payload's* assembly no longer strands rows either.
- **A heavy command republished from the outbox stays in the heavy lane.** When a stored command's
recorded type could not be resolved in the process draining the outbox, republication fell back to
the shared command topic regardless of the lane the command belonged to. Depending on how the lanes
are deployed, the command was then either dead-lettered by the interactive worker or executed on
the interactive lane — the starvation the separate lane exists to prevent. The lane is now recorded
on the envelope when the command is enqueued, so republication no longer depends on resolving the
type.
### Changed
- **Registering two different types under one recorded name now fails.** The trusted-type resolver
previously kept the first and discarded the second without a word, which is indistinguishable from
a registration that never happened: the type simply fails to resolve later, when a stored row is
read. `ITrustedTypeResolver.Register` now throws, naming both types. Registering the same type
again remains a no-op. Reaching this requires two distinct types sharing a full type name *and* a
simple assembly name in one process.
- **`TenantIsolationOptions` follows the options pattern.** The mode can now be bound from
configuration with `Configure<TenantIsolationOptions>(section)` in addition to the
`AddStrataraTenantIsolation(o => ...)` callback, and a second call to the registrar no longer
leaves a conflicting second options instance behind. `Stratara.Mediator` therefore takes a
dependency on `Microsoft.Extensions.Options`.
### Added
- **`CommandEnvelope.Heavy`** records whether a command declared itself long-running when it was
enqueued. Optional and defaulting to `false`, which is how an envelope written by an earlier
version deserializes; the signed canonical form is unchanged, so existing signatures still verify.
