Mibyan supports multiple gateway processes running concurrently — one per profile (default, writer, admin, coder, researcher). Each gateway opens its own connection to platform APIs and delivers messages for its profile’s subscribers. Task subscriptions also cover review feedback. A changes_requested review event is delivered as an actionable review-BLOCK notification. Subscriptions using notify+wake additionally wake the exact originating chat/thread/session so the controller inspects the existing card and current run; notify remains passive-only and wake remains wake-only. Review feedback never creates, unblocks, requeues, or otherwise mutates a task.

​
Single-dispatcher posture

Only one gateway owns the kanban dispatcher. The owning gateway keeps kanban.dispatch_in_gateway: true (the default); every other gateway sets it to false. Why this matters: dispatching is single-owner so multiple gateways do not race to spawn the same work. Notification delivery is profile-owned instead: each gateway polls only subscriptions for profiles whose platform adapters it hosts. The atomic event claim prevents duplicate delivery across watcher processes.

​
Configuration

On the dispatch-owning gateway (typically the default profile), no change is needed. On every other profile gateway, add to ~/.mibyan/config.yaml:
Or set the env var: mibyan_KANBAN_DISPATCH_IN_GATEWAY=false

​
What each gateway does

Non-dispatch gateways still deliver messages for their own platform adapters (Telegram, Discord, etc.). They do not dispatch tasks, and they skip boards that have no subscriptions owned by their profiles.
