Bump WolverineFx from 6.17.3 to 6.18.0

[dependabot]

Updated WolverineFx from 6.17.3 to 6.18.0.

Release notes

Sourced from WolverineFx's releases.

6.18.0

Wolverine 6.18.0

A security-relevant serialization fix, a startup-fatal codegen fix, a silently-dead-listener fix in RabbitMQ, the first F# saga codegen support of any persistence provider, and the CI split that makes "merge when green" mean something again.

If you use MassTransit interop over a durable listener, take this release. See the first section.

⚠️ Security-relevant: reserved envelope headers could be spoofed through the durable inbox

#​3408 — fixed in #​3411

EnvelopeSerializer wrote the typed envelope properties to the wire format and then appended every Envelope.Headers entry verbatim, with no reserved-key filter — and the appended entries came last. Because the reader parses reserved keys straight back into typed properties, a Headers entry under a reserved key silently overwrote the real property on the next read.

A value in envelope.Headers["tenant-id"] is inert while the envelope is in memory. It stops being inert the moment the envelope crosses the serializer — any durable listener, the inbox/outbox, or the scheduled-message store:

1. Something puts tenant-id into envelope.Headers.
2. The durable inbox persists the envelope; the header is appended after the (null) typed property.
3. On read back, env.TenantId is set from it.

saga-id reaches another saga's state, and id rewrites Envelope.Id — the inbox's dedupe identity.

This was live, not theoretical. MassTransitEnvelope.TransferData already copies every incoming MassTransit header into envelope.Headers unfiltered (and by assignment, not TryAdd). Any Wolverine app doing MassTransit interop over a durable listener has had this path open. If that describes you, this release is the one to take.

The fix filters reserved keys on the write side, so the typed property stays authoritative and a reserved key sitting in Headers becomes a no-op. causation-id is deliberately not filtered — DeliveryOptions intentionally carries it as a loose header for Wolverine.Marten's OutboxedSessionFactory, and it is never promoted by the reader.

Startup-fatal codegen fix

#​3399 — fixed in #​3406 — invalid generated class name for batched (array) message types. This one prevents the application from starting.

Fixes

• #​3388 (#​3400) — refuse a competing Marten daemon under Wolverine-managed event subscription distribution. A DaemonMode.Solo/HotCold daemon alongside managed distribution is now an actionable startup exception instead of two schedulers quietly fighting over the same shards.
• CritterWatch #​698 (#​3396) — IAgentRuntime.ApplyRestrictionsAsync persisted the restriction and then never dispatched the commands it computed, so pausing an agent had no immediate effect. Reported by @​erdtsieck against a live cluster.
• #​3385 (#​3403) — a header-identified saga invoked over a gRPC hop failed with an opaque Internal status. It now returns an actionable diagnostic telling you to put the saga identity on the request DTO.
• #​3398 (#​3404) — [AsParameters] now rejects unparseable values in collection query parameters, closing the gap left by the scalar fix in #​3372.
• #​3365 (#​3412) — the Polecat primary IEventStore bridge registered twice, so GetServices<IEventStore>() returned the same store instance two times and anything iterating it double-counted. Polecat's own AddPolecat() had started registering IEventStore and Wolverine was still bridging it as well.
• #​3391 (#​3419) — RabbitMQ: a successful eager channel restart never re-consumed. A callback-exception restart could leave an open channel with zero consumers while reporting State = Connected — a silently dead listener. The listener now defers to ReconnectedAsync(), which re-declares and re-consumes. Also pins the ConnectionMonitor tracking invariant that #​3370 fixed but nothing guarded.

OpenAPI

#​3380 (#​3418) — OpenAPI parameters are now derived from the full binding chain rather than the handler signature alone. Two real defects closed:

• Query/header values bound only by an After/Finally postprocessor were omitted from the operation entirely.
• Route parameter types were read off resolved binding variables, so they degraded to the route constraint (or string) whenever the description was assembled before those frames resolved — which is exactly the build-time OpenAPI / openapi CLI path, because ASP.NET caches the first ApiExplorer read.

More importantly, this ships the OpenAPI shape-test harness that was missing. Adding a shape assertion is now one endpoint plus one [Fact], which is why this class of omission kept shipping unnoticed.

New: Azure Service Bus emulator support

#​3366 (#​3409) — the docs told you to call UseAzureServiceBusTesting(), which only ever existed in Wolverine's own test suite. It is now a real, shipping API:
