Build on Butai
Caliper uses Butai for agents, files and Git inside its CAD interface.
Relayed to the daemon's /v1/*: file tree, diffs, staging, commits, branches, agents, processes.
The framed protocol: panes arrive as cells, so Caliper never wrote a VT emulator.
Everything else — the API is documented.
