"""ayllu.lounge — the collaboration surface, learned from the tribe lounge/bus.

The tribe let souls talk in a shared room. a11oy keeps that, in-memory and honest: each
posted message carries a source label ("brain" when a real model answered, else
"persona-fallback"), so a reader always knows whether they are seeing a grounded reply
or an honest placeholder. `deliberate()` runs a BOUNDED council round — one honest turn
per persona — and never fabricates when no backend is injected.
