Stratara.EventSourcing.WorkerDefaults

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

One-stop IHostApplicationBuilder composites that wire together the Stratara event-sourced stack for each host shape (API, command worker, event-projection worker, saga worker, event-stream-hash worker, outbox worker). Reference this package from each host instead of repeating the per-concern DI call chain.

What's in the box

Composite Wires
AddBackendServices Common framework services (messaging, identity, session, security, mapping, resilience) + mediator + write store + outbox dispatcher. For API hosts that dispatch commands but don't process them.
AddCommandWorkerServices Common + mediator + mediator-worker (hosted service that consumes the command topic into the in-process mediator) + write store + event sourcing + outbox dispatcher.
AddEventProjectionWorkerServices Common + write store + projection-replay state + projection worker.
AddSagaWorkerServices Common + write store + event sourcing + outbox dispatcher + saga worker.
AddEventStreamHashWorkerServices Common + write store + event-stream-hashing worker.
AddOutboxWorkerServices Common + write store + outbox dispatcher + outbox-retry worker.

The composites live in the Microsoft.Extensions.Hosting namespace so call sites read naturally:

// Command-handling worker host:
builder.AddCommandWorkerServices();

// API host that only dispatches commands:
builder.AddBackendServices();

Dependencies

This package pulls the framework's Tier-C pieces (Stratara.Infrastructure, Stratara.Outbox.RabbitMQ, Stratara.Projections, Stratara.Sagas, Stratara.EventSourcing.EntityFrameworkCore) so a single PackageReference is enough for a worker host. The lean Stratara.ServiceDefaults (OTel + Serilog) and Stratara.ServiceDefaults.AspNetCore (health-check endpoints + ASP.NET OTel) stay separate so non-worker hosts don't drag the Tier-C runtime in.

**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**.
