BroadcastAudience

Human-readable name used to identify the audience. Internal only — it is never shown to recipients.

The channel this audience is written for. Must match the type of any broadcast it is attached to.

What the audience selects, resolved to concrete recipients at send time rather than when saved. No rows at all means every recipient the broadcast may reach.

Whether the audience has been soft-deleted. Soft-deleted audiences are excluded from lists but stay queryable by ID, so the record of what a past broadcast was sent to survives.
