CHR0013: Reactor cannot combine EventStore with explicit event sequence

Rule Description

A reactor that declares [EventStore("...")] must use implicit inbox routing. It cannot also define an explicit event sequence.

Severity

Error

Example

Violation

using Cratis.Chronicle.Events;
using Cratis.Chronicle.Reactors;

[EventStore("identity-service")]
[Reactor(eventSequence: "custom-sequence")]
public class UserSyncReactor : IReactor
{
}

Fix

using Cratis.Chronicle.Events;
using Cratis.Chronicle.Reactors;

[EventStore("identity-service")]
[Reactor]
public class UserSyncReactor : IReactor
{
}

Why This Rule Exists

[EventStore] on a reactor is intended to drive outbox-to-inbox routing. Combining it with explicit event sequence configuration creates ambiguous routing intent.
