-- **27 reported cases:** 21 were recorded as fixed by the re-upload; we excluded 3 (one missing image and two with solution or test hints), and kept 3 after inspecting the remaining files.
-- **56 additional tasks with leftover files:** 27 were clean. For 22, copying the installed code into the repository did not pass the verifier. Of the remaining 7, we excluded 1 containing the requested feature and kept 6 after inspection. These checks did not demonstrate an exploit in the retained cases, but do not rule out every possible shortcut.

-We excluded `000092`, `001397`, and `000253` for solution or test hints, plus `000484` because its upstream image was removed. Other validation failures are counted separately above.
