# Host Controller

Python scaffold for the Raspberry Pi / host-side controller.

Host responsibilities:
- state machine orchestration;
- geometric gate;
- manual-mode UI integration;
- serial/protocol session with Teensy;
- controller-job validation;
- telemetry capture;
- logs, manifests, hashes, and `/data/status.json`.

This package is intentionally small for now. Add real hardware adapters behind interfaces and keep state-machine/contract tests fast.
