Orchestration
Different kinds of work, such as standard coding, critical changes, prose, cross-checks, and secrets, are split into bands. You can still pick a model and effort in the session.

Sixteen bands
Bands run from A to P. Human-facing writing stays with MAIN, and secret work prefers local first.
Then the next rung
Each band has a fixed channel order. If the first channel dies or refuses, execution moves to the next.
