ESP32-C6 writes raw sensor bytes straight to microSD. No filtering, no maths — nothing that could cost a sample.

A pure Rust engine parses the binary log and owns every transform: filters, FFT, integration, kinematics estimation.

The companion app turns channels into answers — traces, FFT, histograms, lap timing and rider-to-rider comparison.
