Stratara.Diagnostics
License: MIT.
Generic observability primitives shared by all Stratara packages. Use this to emit Activity / Meter instruments under a uniform source name and stable event-ID schema.
Contents
ApplicationDiagnostics—ActivitySource("Stratara.Application")+Meter("Stratara.Service")+ tag-name constants (correlation.id,causation.id,tenant.id,user.id,event.type,request.type,outcome,outbox.kind) + the metric instruments below. These names are part of the public observability contract — renaming them breaks downstream Grafana/Tempo queries.

Projections and sagas are real-time bus subscribers without a persisted checkpoint, so these report throughput and latency, not consumer lag.
LogEvents—[LoggerMessage]event-ID ranges per domain (ChangeSet=100_000s, BackgroundTasks=101_000s, EventStore=102_000s, …, Messaging=108_000s, Update=109_000s, Saga=110_000s). Even hundreds = info/debug,_1xx= error.LoggerScopeExtensions.BeginCreateAggregateScope/BeginUpdateAggregateScope— pre-baked logging scopes for the create/update aggregate flows.

Showing the top 5 NuGet packages that depend on Stratara.Diagnostics:
| Package | Downloads |
|---|---|
|
Stratara.Sessions
ASP.NET Core middleware and provider for Stratara's Actor/Subject session model. Reads tenant and user from JWT claims (or X-Tenant-Id / X-Client-Id headers) and populates the ambient ISessionContextProvider for every request. |
|
|
Stratara.Mediator
In-process mediator with DI-resolved handlers and pipeline behaviors for the Stratara framework. MediatR-style routing via typed wrapper cache, plus an authorizing decorator and a bucket-lock concurrency primitive. |
|
|
Stratara.Security
Dependency-light key-store and envelope encryption for the Stratara framework. Production IKeyStore implementation (EnvelopeFileKeyStore) with KEK-wrapped, versioned per-scope DEKs (rotation + revoke + crypto-shred), a file-backed master-key provider, and an AES-GCM blob encryptor with purpose-bound associated data. References only Stratara.Abstractions + BCL crypto — no EF Core, RabbitMQ, Redis, or cloud SDKs. |
|
|
Stratara.Validation
Vendor-neutral request validation for the Stratara framework — a mediator pipeline behavior that runs IValidator<T> implementations before the handler and throws an aggregated StrataraValidationException on failure. No FluentValidation dependency; an optional adapter is shipped separately. |
|
|
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. |
GitHub repositories

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.
