Sources & further reading

This guide was compiled from five research passes across the sources below. Two are worth naming as non-sources: the auto-generated “Smart Magnets Market” reports (junk, uncited here), and vendor logo walls (displayed, not verified — only NASA’s Prandtl-M deployment has primary documentation).

Known gap in the record: no independent third-party force testing of coded magnets has been published — the K&J alternating-pole test is the closest thing. If you run or find one, it would be the most valuable document in this field.
