Sekiban.Dcb.Core.Testing

The volatile in-memory stores and helpers Sekiban's own tests are built on, in a package a runtime project has no reason to reference.

They used to be available only from Sekiban.Dcb.Core, in the Sekiban.Dcb.InMemory namespace, where nothing stopped a production host from composing itself out of them — and something didn't. A production system registered the in-memory executor as its ISekibanExecutor, every command succeeded, and no event ever reached the database it had configured.

What this package changes, precisely. These types now have a home a runtime project has no reason to reference: the Sekiban.Dcb.Testing entry points require this package, so a project without it cannot reach them. What it does not do is take the old ones away — Sekiban.Dcb.InMemory remains public in Sekiban.Dcb.Core for compatibility, and code that already uses it still compiles and still runs. The protection against that path is the [Obsolete] pointer, and the opt-in AddSekibanDcbProductionGuard(), whose two answers are not the same answer: an in-process executor is rejected in Production, always — there is no override for it, whichever name it was obtained under — while a volatile store is rejected by default but can be authorised by the named, storage-only AllowVolatileStorageInProduction. A store that will not say what it is (Unknown) stays fail-closed either way. The compile-time boundary is a wall around the new door, not around the old one; the old one closes at the next major.

using Sekiban.Dcb.Testing;

var eventStore = new InMemoryEventStore(domainTypes.EventTypes);

The old Sekiban.Dcb.InMemory types still work and still behave identically — they are [Obsolete], not removed, and they will not be removed before the next major version. Nothing you have breaks today.

Do not reference this package from a runtime project. If you want a local development environment that behaves like production, the answer is a single-silo localhost Orleans host, not an in-memory executor — see the localhost Orleans composition guide.
