Stratara.Diagnostics

License: FSL-1.1-MIT (Functional Source License — source-available; converts to MIT after 2 years). Not OSI-approved OSS.

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.

ApplicationDiagnostics — ActivitySource("Stratara.Application") + Meter("Stratara.Service") + tag-name constants (correlation.id, causation.id, tenant.id, user.id) + metric names (event_source.append.conflicts). These names are part of the public observability contract — renaming them breaks downstream Grafana/Tempo queries.
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.

Quick reference

using var activity = ApplicationDiagnostics.Activity.Source
    .StartActivity("CreateOrder");
activity?.SetTag(ApplicationDiagnostics.TagNames.TenantId, tenantId);

ApplicationDiagnostics.Metrics.EventSourceAppendConflicts.Add(1,
    new("aggregate.type", "Order"));

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.	143
Stratara.Shared Umbrella package for the Stratara framework — source-generated logger extensions for outbox / saga / projection / messaging, domain-event helpers, merge primitives, and the Tier-A/B abstractions surface re-exported as one transitive bundle.	133
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.	46
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.	41

**Breaking release.** The `IKeyStore` and `ISecureBlobEncryptor` contracts changed shape, a new
dependency-light `Stratara.Security` package now owns the production key store and envelope
encryption, and a new vendor-neutral `Stratara.Validation` package adds request validation as a
`Stratara.Mediator` pipeline behavior. Consumers must recompile and adapt call sites; data
encrypted under the previous HKDF-style key model is **not** binary-compatible and needs a
re-encrypt pass on its own schedule.

### Added

- **`Stratara.Validation` — vendor-neutral request validation.** A new package providing a
mediator pipeline behavior that runs `IValidator<T>` implementations before the handler and
throws an aggregated `StrataraValidationException` on failure. Register with
`AddStrataraValidation()` (outermost behavior) and `AddValidatorsFromAssemblyContaining<T>()`.
Only `ValidationSeverity.Error` blocks the request; `Warning`/`Info` failures pass through and
are logged. The package has no FluentValidation dependency — the contract is intentionally
FluentValidation-shape-compatible so an optional adapter can be added later.
- **Validation contracts in `Stratara.Abstractions`** (namespace `Stratara.Abstractions.Validation`):
`IValidator<T>`, `ValidationResult`, `ValidationFailure`, `ValidationSeverity`, and
`StrataraValidationException`. Declaring the exception in `Stratara.Abstractions` lets a
consumer's global exception handler map validation failures to its own error model (e.g.
RFC-7807 ProblemDetails) without referencing the behavior package.
- **`Stratara.Security` — production key store + envelope encryption (dependency-light).** Adds
`EnvelopeFileKeyStore`, a file-backed `IKeyStore` storing **KEK-wrapped, versioned per-scope
data-encryption keys** (rotation, single-version revoke, and whole-scope crypto-shred), plus a
`FileMasterKeyProvider` (`IMasterKeyProvider`, the KEK custody seam), an AES-GCM
`ISecureBlobEncryptor`, and the Development-only `DummyKeyStore`. Register with
`AddStrataraFileKeyStore(configuration)`. The package references only `Stratara.Abstractions` +
BCL crypto + `Microsoft.Extensions.*` abstractions — no EF Core, RabbitMQ, Redis, or cloud SDKs —
so lean consumers can encrypt without pulling in `Stratara.Infrastructure`.
- **New security contracts in `Stratara.Abstractions.Security`:** `KeyScope`, `KeyMaterial`, and
`IMasterKeyProvider`.

### Changed

- **BREAKING — `IKeyStore`.** Replaced `EnsureKeyAsync(level, Guid? tenantId, Guid? userId)` with
`GetOrCreateCurrentKeyAsync(KeyScope)` returning `KeyMaterial` (key id + bytes in one call), and
added `RotateAsync(KeyScope)` and `EraseScopeAsync(KeyScope)`. `RevokeAsync(string keyId)` now
performs a real crypto-shred (the production store no longer treats it as a no-op). Scope
identifiers are `string?` (carrying both slugs and `Guid.ToString()` values) rather than `Guid?`.
- **BREAKING — `ISecureBlobEncryptor`.** `EncryptAsync`/`DecryptAsync` now take a `KeyScope` and a
`purpose` instead of a bare `Guid tenantId`. The encrypted stream gains a leading version byte
(v2) and a `purpose` field; legacy streams without the version byte remain readable (configurable
via `Stratara.Security` options).
- The AES-GCM encryption factory, blob encryptor, and dev key store moved out of
`Stratara.Infrastructure` into `Stratara.Security`; `AddSecurity()` now delegates to it. The
field/JSON `[EncryptData]` path (`ISecureJsonSerializer`) stays in `Stratara.Infrastructure`.

This brings the lockstep family to **22 packable packages**.
