Host checks. These commands do not flash the board. GitHub Actions on main and PRs runs these same commands (firmware, packages, and PCB). On-device hardware: hardware/testing.md.
Unity on the host. Compiles src/settings/validate.cpp plus header-only helpers such as include/servos.h.
pio test -e nativepio run builds firmware. Native tests are pio test -e native, not pio run -e native.
The optional expression library has deterministic asset checks and native renderer tests. These checks require Node 18+ and PlatformIO; they do not access hardware. On the robot, enable those faces with Config / eyes_style=kaomoji (default remains classic).

pio test -e native
pio run -e expression-demoThe expression-demo environment builds a separate OLED-only application without changing the default robot build. For a later bench test, follow its wiring and upload notes, leave the separate servo supply off, and observe all 16 faces through a complete 48-second cycle. Report physical display results separately from host tests and compilation.
Node 18+. No robot.
