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

NuGet packages (9)
Showing the top 5 NuGet packages that depend on Stratara.Abstractions:
| Package | Downloads |
|---|---|
|
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.Shared
Umbrella package for the Stratara framework — source-generated logger extensions for outbox / saga / projection / messaging, 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. |
|
|
Stratara.Outbox.RabbitMQ
Outbox-pattern command and event dispatch for the Stratara event-sourced stack — RabbitMQ IMessageBus implementation, retry worker, mediator command worker, and Redis-coordinated projection-replay state. Azure Service Bus support ships as the sibling Stratara.Outbox.AzureServiceBus package. |

### Fixed
- **`FileMasterKeyProvider` now rejects a master KEK that is not exactly 32 bytes at startup.**
The KEK is used directly as an AES-256-GCM key, which accepts only 16/24/32-byte keys. The
provider previously required merely *at least* 32 bytes, so a longer KEK (for example the
48-byte output of `openssl rand -base64 48`, a common HKDF master-key recipe) passed both
construction and the eager `FileKeyStoreStartupProbe`, then threw
`CryptographicException: Specified key is not a valid size for this algorithm` on the **first**
key creation at runtime — defeating the purpose of the boot-time probe. The provider now
validates the decoded length is exactly 32 bytes and fails fast at boot with an actionable
message (`Generate one with: openssl rand -base64 32`). A 32-byte KEK is unaffected.
- **`EnvelopeFileKeyStore` is now safe for multiple processes sharing one store file** (for
example several containers bind-mounting the same host directory). Previously a process only
read the store once at construction, so a data-encryption key created by another process after
startup was invisible (`GetDataEncryptionKeyAsync` returned `null`, breaking decryption), and
two processes creating keys concurrently could overwrite each other's keys or mint colliding
versions for the same scope. Reads now reload from disk on a cache miss (guarded by the file's
last-write time to avoid reload storms), and every mutation serializes through an exclusive
cross-process lock file and re-reads the latest on-disk state before writing. A networked file
system (NFS/SMB) remains unsupported — it guarantees neither atomic rename nor reliable advisory
locks.
### Added
- **`LogEvents.KeyManagement.KeyStoreReloaded` (112_006)** — debug-level event emitted when the
file key store reloads its state from disk to pick up keys written by another process.
