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, and AddCommandServices, AddEventProjectionServices and AddSagaServices without the bus-fed workers) 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. |

A correctness release. A projection replay could apply a stream's later fact before its first and
then fail on every attempt, leaving the read models it had emptied empty; the two backfills that
prepare existing history for the Orleans execution model's commit-order readers took the same wrong
order. Beyond that, the setting store no longer needs declared settings, and a setting or permission
vocabulary can be declared in parts.
**Upgrading:**
- **If you replay projections, upgrade.** A store in which one save appended several versions of a
stream can hold sequence numbers that run against those versions, and a replay over it could not
complete. No entry is rewritten and no migration is needed.
- **If you implement `IEventStreamRepository` yourself,** override
`GetManyAfterSequenceInStreamOrderAsync` to give your replay the same guarantee; the default keeps
sequence order.
- **If you backfilled a store for a commit-order reader before this release,** the Orleans migration
guide gives the query that tells whether that history holds a stream out of version order, and how
to repair it.
- **A host that declared an empty `SettingCatalog` as a workaround can drop it.** A host that
registers a catalog through a factory and then calls `AddSettingCatalog` or `AddPermissionCatalog`
now fails at registration instead of replacing that catalog.
- No schema change.
### Added
- **`IEventStreamRepository.GetManyAfterSequenceInStreamOrderAsync`**: a range of the store in the order a
replay applies it — each stream's entries in version order, the streams interleaved as their sequence numbers
interleave them, and the range extended until it no longer ends between two versions of one stream. The default
implementation returns `GetManyAfterSequenceAsync`, sequence order, so a repository of your own compiles and
behaves as before; override the member to give your replay the guarantee.
### Fixed
- **A projection replay applies each stream in version order.** A save does not number its entries in version
order — EF Core chooses the statement order and the identity column numbers the rows as they arrive — and the
replay walked the store by sequence number, so it met a stream's later fact before its first. A projection that
reports a missing preceding fact then failed the batch on every attempt, and because a replay empties the read
models first, each attempt left the read side empty. On a store where many saves wrote several versions of one
stream, no replay could complete. The replay now reads through the new repository member; a batch can hold more
entries than `Projections:BatchSize`. No entry is rewritten and no migration is needed.
- **Both commit-order backfills keep each stream in version order.** `CommitTransactionIdBackfill` could end a
batch between two versions of one stream, stamping the later one with the earlier transaction.
`PartitionCounterBackfill` handed out positions in sequence order, so every save it positioned that the store
had numbered against its versions was read inverted by the portable reader. Both now extend a batch until it no
longer ends inside a stream, and the portable backfill positions each stream's entries in version order.
History backfilled with an earlier version is not revisited, because checkpoints stand on its commit records and
positions; the Orleans migration guide gives the query that tells whether a store holds such a stream.
- **The setting store works without declared settings.** `AddSettingStore<TContext>()` and
`AddSettingStoreFromContextFactory<TContext>()` resolved the `SettingCatalog` inside a factory, so a
host that registered the store and `AddStrataraErasure()` but declared no settings built, passed
`ValidateOnBuild` and every start-up check, and failed on its first erasure with *No service for type
`SettingCatalog` has been registered*. The store now registers an empty catalog when none is declared:
the store works, erasure included, and reading any setting through `ISettingProvider` fails as
undeclared. The example on `AddStrataraErasure` was exactly that composition. A host that declared an
empty catalog as a workaround can drop it.
- **A second `AddSettingCatalog` or `AddPermissionCatalog` call no longer replaces the first.** Each
call registered a new catalog and the last one won, so a host declaring its vocabulary per module kept
only the last module's — the others' settings failed as undeclared and their permissions were denied
without a word. Every call now adds to the one registered catalog, in whichever order it runs relative
to the setting store. A setting name declared in two parts throws as a duplicate; a redeclared
permission has no effect and grants to one role accumulate. A catalog registered as a factory cannot be
added to, and the next call now throws `InvalidOperationException` saying so instead of replacing it.
