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.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.Domain
Concrete domain types for the Stratara framework — the Tenant aggregate and its lifecycle events. Stratara's opinionated multitenancy model. |
|
|
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 host that removed or renamed a projection no longer has that
projection's store readers come back on every start and fail each entry; they retire once, as a saga's readers do. A
retired store reader now logs its retirement once instead of three times, and leaves no reminder error behind. No
API change, no schema change and no migration.
### Fixed
- **A reader of a removed projection retires.** On the Orleans execution model, a host that removed or renamed a
projection kept the keep-alive reminders of its store readers. On every start of the silo they brought the readers
back, and each one read the next entry of its partition, failed it because no projection of its name was
registered, and tried again on the next tick, without end — a warning per partition and entry. Such a reader now
retires the first time it is brought back, as a saga's reader already did: it unregisters its keep-alive, logs
`117_136` `UnregisteredProjectionReaderRetired` (Information) once, reads nothing and deactivates. Its checkpoints
stay, so a projection registered again resumes where it stopped; *Operate the Orleans execution model* says how to
delete them. In a rolling deployment that adds a projection, a reader that lands on a silo of the earlier version
refuses a rebuild's or a replay's pause, which then fails naming it, and a wait counts its partition as behind.
- **A retired store reader logs its retirement once.** A reader that retired as it was activated — of a partition
beyond a lowered partition count, or of a saga the silo no longer registers — deactivated before it answered the
call that activated it. Orleans forwarded that call to a new activation, which retired again, so the retirement was
logged three times per reader and the keep-alive tick ended in `Could not deliver reminder tick` at Error. The
reader now answers the call first and deactivates after it.
