 the nine 1.2 m scans nobody had done (CC BY-NC 4.0; model output, end status in each file's note).

+End checks on my nine lines (automatic only): 5 of 18 ends pass, 4 are flagged and 9 can't be judged.
+Can't be judged means the tilt check's planted fake tilt slipped under its bar, because those lines bend as much
+in the middle as the fake tilt does. 5 of the 13 published human-made lines fail that control the same way, so a
+slope rule can't decide these ends. Every end passes the papyrus support check. No end has been checked on CT by a
+person. usable_ends in each file's metadata says which ends to rely on.
