Manifest scan, slow beat

Variant: Slow beat

The same manifest integrity check, paced as a deliberate patrol rather than a quick pass: the scan line takes noticeably longer to cross the rows and the unlisted record surfaces late in the sweep. Use it when the check is a long-running background job and a fast cycle would misrepresent the work. Only the clock changes — geometry, easing and keyframe percentages are identical to the single-beat sibling, so the detection still lands at the same point in the pass.
