Development

These documents should be considered the source of truth for ongoing development.

Priority order:

1. docs/project-state.md
2. docs/hardware-status.md
3. docs/protocol.md
4. docs/pico-architecture.md
5. docs/ui-wireframes.md

Implementation should follow documented architecture unless explicitly updated in the documentation first.
