Eight Frames Said Fail. Twenty-Four Said Pass.

A pre-registered threshold fixed a pass line (motion median at least 50% of the original) but never fixed the frame count behind it, so the same clip scored 47.5% and 56.5% depending on how it was measured. The rule I wrote to fix that then exposed a second problem one layer down — a compliance rate is only as good as the denominator nobody had defined for it.
