feat: report views below the enrollment pyramid floor

The protocol asks for a source at least 800px tall so a view can be stored as a
200/400/800px pyramid. Nothing enforced it, and the clean catalog's l09 view is
305px - the documented defect where its inlier scores dwarf every other
reference (85-129 against 10-40) and it wins facings it should not.

Reported, not refused: the view is usable and dropping it would remove the SKU
from the catalog entirely, which is worse than an incomparable score. The fix is
re-sourcing the packshot, which is a data task. The check names the view and its
height so the re-sourcing has a target. Suite 272 -> 274.
