Before you rely on it
Read the Known limitations section of the README before you wire this into anything that matters. Every one of these systems is a floor, not a proof: it catches the failures it was written to catch, and it will not catch a failure nobody has described to it yet.
There are no testimonials, results or revenue claims on this page because there is no verified purchase or customer outcome to report for it.
