Stratara.EventSourcing.WorkerDefaults

License: MIT.

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.

### Added

- **Event upcasting (`IEventUpcaster`).** Persisted events can now be transformed from an older
 on-disk schema into the shape the current event record expects, applied on read before the payload
 is deserialized. Register upcasters with `AddEventUpcaster<TUpcaster>()`; each implements
 `IEventUpcaster` (`SourceEventTypeName` / `TargetEventTypeName` plus `JsonNode Upcast(JsonNode)`) and
 they chain across successive schema versions (v1→v2→v3), including event-type renames — the source
 type no longer needs to exist in the assembly. Matching ignores the assembly `Version` segment, and
 a cyclic or duplicate-source chain is rejected. Hosts that register no upcasters are unaffected
 (transparent pass-through). Snapshots are not upcasted — change an aggregate's shape and rebuild its
 snapshots.

### Changed

- **Copyright holder corrected to the full legal name "Norbert Heinz Rosenwinkel"** in the `LICENSE`
 file and in the `Authors` / `Copyright` package metadata. No code or licensing-terms change — the
 license remains MIT.
