EventStores.Name, Reminders.Id, DataProtectionKeys.Id, and Patches.Name were declared without a maxLength. On SQL Server that emits NVARCHAR(MAX), which cannot be used as a key column in an index — the primary key constraint creation failed with SQL error 1919, taking down silo startup for every SQL Server integration job. Apply maxLength: 200 and nullable: false to those columns. The fix existed on the branch before the merge of main and was lost during conflict resolution; this restores it on the current merge result.
SQL Server support is not yet publicly released, so there are no real deployments running v15_0_0 in production that would need a separate v15_1_0 to evolve from. Collapse all cluster table creation into one migration to reduce maintenance overhead and make the initial schema trivial to read. Tables merged into v15_0_0: Users, Applications, DataProtectionKeys, Patches, SystemInformation. Down() drops them in reverse order.
Add a discover-implementations skill and a DI rule that codify the pattern from the IReactorSideEffectHandlers fix: inject IInstancesOf<TInterface> to enumerate all implementations of an abstraction, mark each implementation with [Singleton] (or rely on the IFoo → Foo convention for transients), and delete the services.AddSingleton<TInterface, Impl>() registrations. IEnumerable<TInterface> for discovery requires hand-maintained registrations everywhere — new implementations silently do nothing until someone remembers to register them, removed types leave dead registrations, and spec setups must mirror production. IInstancesOf<T> pushes that knowledge into the implementation itself.
The previous merge of origin/main inadvertently reverted the OpenIddict SQL storage layer to its pre-branch state. Restore it: token, authorization, and scope entities; matching IOpenIddictTokenStore / AuthorizationStore / ScopeStore implementations; DbSet wiring on ClusterDbContext; and Tokens / Authorizations / Scopes table creation folded into the consolidated Cluster v15_0_0 migration. This sits alongside main's own user/application/data-protection-key work — they are complementary auth storage concerns, not duplicates.
…ict keys The compile-time #if DEVELOPMENT branch tied ephemeral key generation to the build configuration. That made it impossible to run a Release build against a local Development environment for testing, and it fell back to throwing when no certificate was configured even on a genuine development machine. Replace the preprocessor branch with a runtime check against the standard DOTNET_ENVIRONMENT / ASPNETCORE_ENVIRONMENT variables. Same production behavior (throw without a certificate), better local ergonomics.
…e change ReactorSideEffectHandlers' constructor now takes IInstancesOf<T> instead of IEnumerable<T>. Wrap the test-side handler arrays in KnownInstancesOf<IReactorSideEffectHandler> at every call site — EventStoreForTesting plus the seven ReactionInvoker invocation specs. Also drop the now-unused 'using Cratis.Chronicle.Reactors.SideEffects;' from ChronicleClientServiceCollectionExtensions left over from the previous registration removal.

Two files came in via the merge of main that referenced types or call signatures the branch no longer has: - many_events_with_subjects.cs (PII / subject append spec) was added in main at Integration/DotNET.InProcess/...; git moved it into the Integration/Client/... folder during the merge but the namespace still pointed at Cratis.Chronicle.InProcess.Integration and the fixture was ChronicleInProcessFixture, neither of which exists in Integration/Client. Switch namespace to Cratis.Chronicle.Integration and fixture to ChronicleFixture, matching the sibling an_event spec. - EventWithSubjectAndPII.cs likewise used the InProcess namespace — align it with the Client folder's namespace. - Storage.Sql.Specs Sink spec's CreateContext and ReadModelTable mock setup were missing the IReadOnlyList<ProjectedColumn> columns parameter the branch added to ReadModelDbContext and IDatabase earlier on the branch. Pass an empty list.
…onvention EventStore.GetRequiredService<IReactorSideEffectHandlers>() failed at runtime with 'Cannot dynamically create an instance of type ... IReactorSideEffectHandlers. Reason: Cannot create an instance of an interface' for every ChronicleClient created without a host service provider — integration fixtures included, where each test reset went through this path. The previous code path worked because the type was registered explicitly with services.AddSingleton<IReactorSideEffectHandlers, ReactorSideEffectHandlers>(). The branch removed that registration as part of switching to IInstancesOf<T> for implementation discovery, so when no host DI container is in play DefaultServiceProvider had nothing to fall back to and Activator.CreateInstance on an interface threw. Teach DefaultServiceProvider the same conventions a real container honors: - IInstancesOf<TInterface> → InstancesOf<TInterface>(Types.Instance, this) - IFoo → Foo by namespace, instantiated via its widest constructor with parameters recursively resolved through the same provider This restores the discovery model the IInstancesOf rule promises: adding a new implementation no longer requires editing a composition root, and falling back to DefaultServiceProvider gives the same behavior as the host DI container would.
The previous attempt put convention-based resolution into DefaultServiceProvider — that solved the symptom but leaked DI-container behavior into a stub provider and would have to grow every time another consumer hit the same shape. Revert it. Instead, mirror the existing ComplianceMetadataResolver pattern in ChronicleClient: construct ReactorSideEffectHandlers eagerly with new InstancesOf<IReactorSideEffectHandler>(Types.Instance, _serviceProvider) and pass it to EventStore as an explicit constructor parameter. The EventStore no longer pulls IReactorSideEffectHandlers off the service provider at all, so the DefaultServiceProvider fallback path never has to know about it.
…I spec
Two unrelated regressions came in with the merge of main and only
surfaced once the spec matrix actually exercised them on the branch.
ConstraintsStorage.GetDefinitions / SaveDefinition translated
.OrderByDescending(_ => _.Version) down to the database — SQLite's
EF Core provider rejects ulong in ORDER BY ('SQLite does not support
expressions of type ulong in ORDER BY clauses'). Materialize the
candidate rows first, then sort client-side. Per-name version history
is small enough that this is fine, and it keeps Version a ulong in
the kernel (narrowing to long would change semantics, casting per
provider would diverge).
many_events_with_subjects PII spec was authored on main against the
DotNET.InProcess project (MongoDB only) and ran fine there. When the
merge moved it into Integration/Client it started running across the
full provider × runtime-mode matrix, and its Mongo-specific reads
(GetCollection<BsonDocument>, MongoDBContainer.GetMappedPublicPort)
fail on every non-Mongo leg — the kernel container has no embedded
mongod. Gate the at-rest verification (storage layout, encryption
keys) on the MongoDB backend; keep the storage-agnostic facts (tail
sequence number, round-trip decryption via EventLog) running
everywhere.
The spec came in via main against the pre-typed-column ReadModelDbContext (no ProjectedColumn list). When I rebuilt it for the branch's signature in 2c22fc5 I passed an empty list, which compiles but blows up at runtime: 'The entity type test_read_models (DynamicReadModelEntity) requires a primary key' — without any column, EF has no IsKey marker to hang the PK on. Build a JsonSchema declaring the two properties the spec writes through (name string, roles array of object), derive the column list via the same ProjectedColumns.ForSchema helper the production sink uses, and feed it into both the sink (through CreateReadModelDefinition) and ReadModelDbContext. They now agree on shape and EF is happy. Verified locally: 4 facts pass.
ObserverFilters (EventSourceType, EventStreamType, Tags) were checked
at batch granularity: 'skip the batch only when NO event in it matches
the filter'. Whenever a batch carried at least one matching event the
remaining non-matching events flowed straight through to the
subscriber, which then dispatched them to the handler — observable as
'reactor with [EventSourceType("order")] sees the non-matching event
too' on SQL out-of-process integration runs (MongoDB tends to deliver
events one at a time, so the per-batch check happened to coincide with
the intended semantics there). The structural event-type subscription
check at the top of Handle had the same shape and the same problem.
Compute the matching subset of events up front via a new
EventMatchesSubscription helper that combines the structural
event-type check with all three ObserverFilters, and feed only the
matching events into the dispatch path. eventsToHandle now derives
from matchingEvents instead of the raw batch, so the subscriber sees
exactly the events the observer subscribed to.
To avoid re-fetching trailing filtered-out events on every roundtrip,
advance NextEventSequenceNumber past observedTailEventSequenceNumber
when every matching event in the batch succeeded; partial success
keeps the conservative result.LastSuccessfulObservation.Next() so the
next attempt retries from the first unhandled matching event.
Validated locally: all 320 for_Observer specs pass.
Replay races sibling partitions through their own events independently of each other. When a root projection's HandleEvent step calls AddPropertiesFrom(InitialModelState) it produced a PropertiesChanged covering every property in the read model — including children collections like Features. A subsequent root event whose ChildAdded landed first would already have populated the parent document's Features array; the root's PropertiesChanged then $set Features back to [], wiping the children. The sequential append path got lucky because partitions were drained in order (root before children), but replay drives each partition through its own job step so the writes interleave. The visible symptom is and_projection_is_replayed of the deep-hierarchy spec: Module.Name materialises, Module.Features is empty. Walk the projection tree once when filling the initial-state diff and skip every children property path the root owns. Those paths are managed exclusively by ChildAdded / ChildRemoved across the read model's lifetime, never by a root $set. Verified locally: 410 Core specs + 396 Infrastructure specs pass.
f4316ab switched the dispatch path from a batch-level skip to a per-event match check, but split the filter from the sequence-number filter into two stages. When a batch happened to land with matching events whose sequence numbers were all already < NextEventSequenceNumber — re-fetches after restarts, partition-cursor gymnastics during catch-up etc. — the new shape produced a non-empty matchingEvents but an empty eventsToHandle, fell through the dispatch block without entering it, and left State unchanged. The next poll fetched the same batch and looped, never letting the observer transition to subscribed/active. for_EventStoreSubscriptions tenant-outbox-forwarding stalled at WaitTillSubscribed under both inprocess+mongodb and outofprocess+postgresql because of that loop. Compose the two filters into a single Where() so eventsToHandle is defined as exactly the events we intend to dispatch, then early-return with an explicit cursor advance past observedTailEventSequenceNumber when that set is empty. The early-return covers both "no matching event types in the batch" and "matching events are already past" with the same forward-progress bookkeeping. Verified locally: 320 for_Observer specs pass.
36693a6 hoisted both filter passes into a single Where() and added an unconditional cursor advance when the resulting set was empty. That regressed two existing for_Observer specs (and_events_has_already_been_handled, and_subscription_is_disconnected): when the entire batch lies before NextEventSequenceNumber the cursor should stay put and no state write should be emitted, but the early return was rewinding NextEventSequenceNumber to the batch tail's Next() and writing it. Guard the advance on observedTailEventSequenceNumber >= tailEventSequenceNumber. The forward-of-cursor path (the case the previous commit was protecting against — a batch whose only forward-of-cursor events are non-matching) still advances and writes state. A batch that lies entirely behind the cursor now exits without touching state, matching the long-standing spec contract. Verified locally: all 1531 Core specs pass.
f4316ab + 36693a6 + 7d47ebd fixed the partial-batch filter leak (reactor with [EventSourceType] saw events from the wrong source) by hoisting the filter into a single Where(), but the rewrite also changed the state-advancement semantics — chasing the batch tail when every matching event was handled, asymmetric handling between failure and success — and that knocked out for_Reducers retry tests (3 scenarios x 6 facts) plus a chunk of for_EventStoreSubscriptions. Pre-existing for_Reducers passes regressed from 67 to 56. Strip the rewrite back to a one-line behavior change: keep all four existing batch-level "skip if nothing matches" early-exits and the original NextEventSequenceNumber = result.LastSuccessfulObservation.Next() on success, but apply the same EventMatchesSubscription helper to filter eventsToHandle before dispatching to the subscriber. Reactors with EventSourceType / EventStreamType / Tags filters now only see matching events; the bookkeeping for failed partitions, retries, and catch-up paths is byte-identical to d979347. Verified locally: 1531 Core specs pass.
…r tests ed5a815 (Exclude children paths from root projection's initial-state diff) was speculatively fixing the deep-hierarchy replay scenario, but the latest CI shows the deep-hierarchy spec stayed at 6 failures and the change picked up new regressions: for_Reducers when_handling_event.and_it_fails (but_not_second_time + but_not_third_time) went from passing to failing (-11 tests on outofprocess+sqlite), and two new flake-shaped failures appeared on Projections inprocess/oop mongodb (when_projecting_with_watcher.should_receive_same_model, when_projecting_with_join_for_children.with_from_every.should_set...). Pulling that change back to d979347's behavior keeps the original deep-hierarchy bug — to be revisited separately — but stops the net regression in for_Reducers and the Projections watcher/join paths. Verified locally: 1531 Core specs pass.
bde819e kept what looked like a minimal Where() clause change, but even that one-line addition was enough to regress for_Reducers when_handling_event.and_it_fails (but_not_second_time + but_not_third_time) on outofprocess+sqlite and to flip two passing Projections tests (waiting_for_each_event.with_two_event_types) into NullReferenceException territory on inprocess+mongodb. The common shape — retry / catchup paths that depend on a specific sequence of failures and recoveries — won't tolerate the per-event filter without a deeper rethink that I don't have time to land safely tonight. Roll Observer.Handling all the way back to d979347 to clear the regression surface for the rest of the CI matrix. The original per-batch filter leak (reactor with [EventSourceType] still sees non-matching events when the batch carries at least one match) is back; that's the bug we set out to fix in f4316ab and the right follow-up is a targeted fix at the subscriber's dispatch layer rather than in the observer's batch handling. Verified locally: 1531 Core specs pass.
