Stratara.Sessions
License: MIT.
Concrete session-context provider + ASP.NET Core middleware for Stratara's Actor/Subject session model. Reads tenant + user identity from JWT claims (with optional X-Tenant-Id / X-Client-Id header fallbacks), populates the ambient ISessionContextProvider, and exposes the Actor/Subject pair to every request.
Since 3.0.10: the
X-Tenant-Idheader fallback is opt-in viaSessionContextOptions.AllowTenantHeader = true(defaultfalse). Without the gate, any authenticated principal could pick the tenant their request operated against in hosts whose JWT does not carry the tenant claim. Embed the tenant id in the JWT claim set, or opt in explicitly when an upstream platform-admin role check guards the header.
Quick start
// Program.cs / Startup.cs
builder.Services.AddSessionContext();
// In the middleware pipeline:
app.UseMiddleware<SessionContextMiddleware>();
Then resolve in any scoped service:
public sealed class SomeHandler(ISessionContextProvider sessionContextProvider)
{
public async Task HandleAsync(...) {
var session = sessionContextProvider.Current
?? throw new InvalidOperationException("Session context not set");
// session.TenantId = Subject (data owner) — used for filtering / encryption AAD
// session.UserId = Subject user (nullable)
// session.ActorTenantId = Actor (who triggered) — audit trail
// session.ActorUserId = Actor user — audit trail
}
}
What's in the box
SessionContextProvider—internal sealedimpl ofISessionContextProvider, scoped per request. Writes Activity tags (correlation.id,causation.id,tenant.id,user.id) automatically onSet/Clear.SessionContextMiddleware— ASP.NET Core middleware that extracts tenant + user fromClaimTypes.NameIdentifier+stratara:tenant_idclaim (with optionalX-Tenant-Idheader fallback gated bySessionContextOptions.AllowTenantHeader) and constructs aSessionContextwith Actor=Subject (the default UserPlatform case).SessionContextOptions— configuration (SessionContextsection) controlling the header fallback gate. Bind viaservices.Configure<SessionContextOptions>(...)orservices.AddOptions<SessionContextOptions>().Bind(...).StrataraClaimTypes— claim-name constants (stratara:tenant_id).DefaultTenantIdentifier— sentinelGuidused when no tenant claim or header is present (typically anonymous / system flows).AddSessionContext()DI extension — registers the concrete provider as a scoped service againstISessionContextProvider.
Adopting the Actor/Subject model
For most operations Actor equals the data-owner Subject — a user acts on their own tenant's data. The split only diverges for:
- PlatformAdmin cross-tenant operations (Subject = customer tenant, Actor = admin tenant)
- Anonymous endpoints (Actor =
Guid.Empty, Subject = the just-minted tenant) - System / saga flows (Actor =
SessionContext.SystemActorTenantId/SystemActorUserId)
Consumers that reject ambient context (libraries that prefer explicit TenantId parameters everywhere) do not need to take this package — Stratara.Mediator and the rest of the framework work without an ISessionContextProvider registered as long as no path requires it.

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.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. |

Stratara.Infrastructure
Infrastructure glue for the Stratara framework — authorization decorators, configuration providers, and DI composition helpers that wire Mediator, Outbox, Identity, and EF Core into a hosted app. |

API keys can now be bootstrapped. Issuance always generated the key itself, which does not fit the
setups where server and caller have to share a key *before* either starts — container orchestration,
CI provisioning, self-hosted bundles, end-to-end test hosts. This release adds an import path for a
key the caller already holds, plus the canonical key format as public API so callers generate values
instead of inventing them.
### Added
- **`IApiKeyStore.ImportAsync` — store a machine key whose raw value the caller already holds.**
Issuance generates the key itself, which is the wrong shape when server and caller must share it
*before* either boots: container orchestration, CI provisioning, self-hosted bundles, end-to-end
test hosts. Without this path, consumers bypassed the store and reimplemented its internals (the
digest format and the machine-key membership row) — a copy that keeps compiling after the store
changes and fails as a runtime 401. Import is idempotent, so it can run unconditionally on every
boot: a value that is already stored returns the existing descriptor and the stored key is never
mutated, so a changed configuration cannot escalate a key's roles or extend its expiry unnoticed.
Revoked, expired, and foreign-tenant values are rejected rather than silently adopted, and
concurrent replicas racing the same first import converge on one key. Machine keys only —
`ApiKeyImportRequest` carries no `UserId`.
- **`ApiKeyFormat` (`Stratara.Abstractions.ApiKeys`) — the canonical raw-key format as public API.**
`CreateRawKey()` generates `stk_` plus the Base64Url encoding of 32 CSPRNG bytes; `IsWellFormed()`
checks that shape. `ImportAsync` accepts only well-formed values: the store keeps its stored
digest unsalted because a generated key carries 256 bits of entropy, and a hand-picked value would
quietly invalidate that. Generate keys out of band with `CreateRawKey()` and keep them in a secret
store — the type lives in the abstractions package so host-builder and orchestration projects can
reach it without referencing the storage implementation.
- **`InMemoryApiKeyStore` (`Stratara.Testing`) — the drop-in double for the API-key store**,
mirroring issuance, import, fail-closed validation, revocation, and the erasure sweeps, and
materializing machine keys into a membership store you can share and inspect.
### Changed
- **API-key lifecycle events are now logged** (`Stratara.Diagnostics` event-ID range 116_000):
import, idempotent repeat, and a repeat that supplied different parameters. Key ids and tenant
ids only — never the raw key or its digest.
- **For implementers of `IApiKeyStore`:** the interface gained `ImportAsync`. Custom implementations
need the new member; callers are unaffected.
