"""Compatibility defaults: deliberate speech and multi-source attention routing.

Documented Contract:
1. Attention policy (`attention.plan`):
   - 'operator': wake('operator')
   - 'discord.dm': wake('directed')
   - 'discord.mention': wake('directed') (urgent directed notifications must wake immediately)
   - 'discord.ambient': defer(8) (shipped ambient participation policy: batches with 8-second window)
   - Any unknown source: raises ValueError('unknown source; never silently discard it')

2. Delivery policy (`delivery.review`):
   - DeliveryDecision.allow() for authorized destinations
