Stratara.EventSourcing.WorkerDefaults
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
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.

Two operational fixes, both found while a consumer rolled out bus-envelope signing and reasoned
about rebuilding its read models: a projection replay now survives a passing failure, and an
integrity failure says whether the signature was absent or wrong. Additive on every published
surface.
### Added
- **A projection replay retries a failing batch before it gives up.** Each batch — the read from
the event store and the application of its entries — now runs under a new named policy,
`ResilienceNames.ProjectionReplayBatch`: five attempts in all, exponential backoff from one second
with jitter between them, any exception except cancellation. A read-store timeout or a
dropped connection mid-rebuild no longer ends the replay; a failure that persists through every
attempt ends it exactly as before, with the same failure record. A retried batch is applied
again from its first entry in a fresh scope, which relies on the guarantee projections already
give under at-least-once delivery: a second application converges (see *Write handlers that
converge rather than accumulate* in the projection guide). Each failed attempt logs a new
warning, `104_011`. `AddResiliencePipelines` registers six policies rather than five. Nothing
about truncation, ordering, progress, the failure record or the lease changes.
### Changed
- **An integrity failure now says whether the signature was absent or wrong, and the existing
warning and error ids fire only for a signature that is present and does not verify.** An
unsigned envelope — what every not-yet-restarted publisher emits during a `Permissive` roll —
was logged as *"signature mismatch"* under the same id as a key mismatch or tampering, so an
operator could not tell a rolling restart from an attack without correlating host start times.
Four new event ids carry the unsigned case: `105_004` (command, permissive), `111_004` (event
bundle, permissive), `105_105` (command, strict) and `111_105` (event bundle, strict). The
existing `105_003`, `111_003`, `105_104` and `111_104` keep their numbers and their level but
now mean a present signature that did not verify; an alert keyed on one of them goes quiet
during a roll instead of firing for every unsigned message. Strict-mode rejections name the
case in their exception message. `BusEnvelopeIntegrityVerifier.Verify` gains an overload with
`out BusEnvelopeIntegrityFailure` (`None`, `Absent`, `Invalid`); the existing overload and the
`BusEnvelopeIntegrityResult` values are unchanged. An absent signature no longer reaches the
signer, which already answered `false` for it.
