RapidPy — RAPID magnetometer control architecture Diagram

Measurement integrity

• One block = zero, four orientations at 0/90/180/270, zero
• A one-flux-count step between the zeros is rejected outright
• Recovery re-zeros and repeats the whole block, never a value

Fail closed on hardware

• Missing driver, port, adapter, or calibration blocks preflight
• Simulators exist only in explicit no-comm mode and are labelled
• Unconfigured lift positions block a run rather than being invented

Evidence you can audit

• Counter and DVM kept apart, tied to one latch identity
• Output staged, fsynced, then published with an atomic rename
• Provenance names the holder record, calibration, and commit

VB6 parity

• Baseline weights i/5 and the four CorrectedSample rotations
• Fischer CSD, induced vector, and the three signal ratios
• Deterministic fixtures pin the numbers against modMeasure.bas
