Centered on the resume task: build the infra-ops-owned Worldtree per-deployment
config repo + deploy tooling (operator-directed) with the one-time
worldtree-dev boundary agreement. Also records: The Booth shipped (v0.1.3), the
jackdaw-compose nh3-dev deploy, and the Worldtree #376 arc closed (per-instance
config ruled by-design). Two detail files + the /tmp handoff.
