The publisher-stamped `envelope.Store` (the main store) + carried through the inbox and `FlushOutgoingMessagesOnCommit` then pointed at the publisher's + `wolverine_incoming_envelopes` table while the receiving Marten session was connected to the ancillary + database, surfacing as `42P01: relation "public.wolverine_incoming_envelopes" does not exist`. Closes #2669. + - The receiving handler's ancillary-store association now wins over the publisher's: `assignAncillaryStoreIfNeeded` + in `DurableLocalQueue` and `DurableReceiver` no longer short-circuits when the envelope already has a `Store`. + - The Marten listener's in-transaction inbox `UPDATE` is gated on `Uri` equality (not `IMessageStore.Id`) so + cross-store envelopes deterministically skip the in-transaction shortcut and the envelope's owning store + handles the mark-handled separately. + +### WolverineFx.RabbitMQ + +- Added a public fluent API for multi-node RabbitMQ cluster failover via `RabbitMqTransportExpression.AddClusterNode(...)`. + Two repeatable overloads — `AddClusterNode(string hostName, int port = -1)` (copies the factory's `Ssl` settings + onto the new endpoint) and `AddClusterNode(AmqpTcpEndpoint endpoint)` (power-user). Cluster nodes propagate to + virtual-host tenants and surface in connection diagnostics. Closes #2659. + +### WolverineFx.Polecat + +- Fixed `FlushOutgoingMessagesOnCommit` `NullReferenceException` on every Polecat-backed handler. The + `OutboxedSessionFactory` was constructing the listener with `null!` for the `SqlServerMessageStore` on the + assumption that a post-construction setter would fill it in — but the listener's field is `readonly`. Replaced + with a `resolveSqlServerMessageStore()` helper that mirrors `PolecatEnvelopeTransaction`'s two-shape + resolution (`SqlServerMessageStore` + `MultiTenantedMessageStore { Main: SqlServerMessageStore }`) so multi-tenanted + Polecat works too. Closes #2668. + +### WolverineFx (core) + +- New `DocumentStores` collection on `ServiceCapabilities`, mirroring the existing `EventStores` walk for the + document side. Walks `IDocumentStoreUsageSource` registrations (Marten and Polecat both implement it via + `IDocumentStore`), dedupes by `Subject` URI to avoid double-counting when the same instance wears both + event-store and document-store hats, and stuffs `DocumentStoreUsage` snapshots into the capabilities surface + so CritterWatch can render document-side configuration the same way it already renders event stores. + +### Dependencies + +- Bumped `JasperFx` 1.28.2 → 1.29.0, `JasperFx.Events` 1.31.1 → 1.33.1, `Marten` + `Marten.AspNetCore` + 8.32.0 → 8.35.0. The bumped JasperFx packages provide the `IDocumentStoreUsageSource` and `DocumentStoreUsage` + types the new capability surface depends on. + +## 5.36.2 + +### WolverineFx (core) + +- Reworked the EF Core + outbox flush pipeline to ensure cascading messages aren't sent before the EF Core + transaction commits. New `IFlushesMessages` abstraction; `EnrollDbContextInTransaction` and the HTTP chain + codegen now route the post-handler flush through it so the commit-then-flush ordering is enforced + consistently. Companion fix to 5.36.1 — the codegen guard from 5.36.1 stopped emitting the duplicate flush + call, this release reworks the underlying machinery so the ordering invariant holds even under future + codegen changes. + +## 5.36.1 + +### WolverineFx.EntityFrameworkCore + +- Fixed a code-generation bug where the EF Core transactional middleware in Eager mode (the default) emitted + a duplicate `messageContext.FlushOutgoingMessagesAsync()` call BEFORE the wrapping + `efCoreEnvelopeTransaction.CommitAsync(...)`. The early flush sent cascading messages through the transport + sender while the EF Core transaction (and its `wolverine_outgoing_envelopes` row) was still uncommitted, so + the post-send `IMessageOutbox.DeleteOutgoingAsync` ran on a separate connection that couldn't see the + uncommitted INSERT — the row was left stranded for the durability agent to re-send (at-least-once instead of + exactly-once). Only manifested on HTTP endpoints; message handler chains were unaffected. Lightweight mode + is unchanged.
