North

Local work, visible boundaries.

North is the operator workspace for work that needs memory, action, and proof to stay close together.

Local-first

North keeps serious work close to the operator instead of burying it in abstraction.

Raven-gated

Risky action is classified before it moves.

Receipt-bearing

What happened remains inspectable after the moment passes.

System

A small set of roles. Clear responsibility.

Memory Lane preserves continuity. Raven gates action. mdash keeps proof near the work. Long Arc is the house those systems belong to.
