Current P1 state

Cabinet, control concept and computer platform are defined while the final coax cut-out remains intentionally open until the real driver is checked. The build log follows the same six-phase structure as every other project.

P0.2 is archive material.

The 24 August 2026 documents remain downloadable for traceability but are not a P1 manufacturing release.
