Description

notification_target_for_channel() assumes channel owner is always the notification target — No abstraction for custom routing logic or multi-user scenarios. Future requirements for flexible routing will require schema changes.

Triage verdict: TOO LARGE — architectural concern, not a bug

notification_target_for_channel() correctly returns the channel owner as the notification target. This is used as a fallback in the notification resolution chain (explicit user → channel owner → ctx.user_id). The single-owner assumption is correct for the current single-user architecture. Multi-user routing would require broader schema changes and is a future enhancement, not a bug fix.
