Stratara.Abstractions
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
License: MIT.
Contract interfaces and wire-level POCO records for the Stratara framework. Library-safe — depends only on Microsoft.Extensions.DependencyInjection.Abstractions, Microsoft.Extensions.Logging.Abstractions, and Stratara.Contracts. No EF Core or message-bus runtime.
Use this when you need to reference Stratara types without pulling in any concrete implementation (Mediator runtime, EF Core, RabbitMQ, etc.). Typical consumers: handler/projection libraries that ship without a host.

Why split
NuGet consumers without an event-sourcing host can adopt Stratara's CQRS contracts and authorization model without dragging in EF Core, RabbitMQ, or the WriteStore.

|---|---|
|
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.Domain
Concrete domain types for the Stratara framework — the Tenant aggregate and its lifecycle events. Stratara's opinionated multitenancy model. |
|
|
Stratara.Resilience
Polly-based named resilience pipelines pre-wired for the Stratara framework's messaging and command/event dispatch paths. Four named pipelines registered via AddResiliencePipelines(). |
|
|
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. |
|
|
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. |

A fix for hosts on the Orleans execution model. A store reader that catches up a large backlog and a singleton
work that runs long now answer their keep-alive, so neither leaves reminder errors in the silo's log. A silo that
joins while a singleton work runs long on another silo no longer fails its start. No API change, no schema change
and no migration.
### Fixed
- **A busy store reader or singleton work answers its keep-alive.** On the Orleans execution model, a projection or
saga reader that caught up a backlog for longer than the runtime's response timeout made its keep-alive tick wait
behind the catch-up, and Orleans logged `Could not deliver reminder tick` at Error, once per partition and
keep-alive period. A singleton work whose run outlasted the timeout did the same. Nothing was lost, but a large
catch-up left dozens of errors on the silo. The keep-alive and the poll now start a catch-up where none is
running and do not wait for it. A partition is still read by one catch-up at a time, and a commit during a
catch-up is still applied by it. A singleton work's keep-alive interleaves with its run, and runs still never
overlap.
- **A silo starts while a singleton work runs long.** A silo that started while a singleton work it registers ran
longer than the response timeout on another silo waited for that run in its own start. The start then failed
with a `TimeoutException`. The call a starting silo makes to each singleton work and store reader now
interleaves, so the start goes on.
- *Operate the Orleans execution model* says that a durable timer whose handler outlasts the response timeout
still makes Orleans log `Could not deliver reminder tick` for that tick, and that the line says nothing about
the timer. It also says that, outside a deploy, the line now points to an unreachable store reader or singleton
work rather than a busy one.
