  -> Floor is at its fixed point (0 Major, 0 Minor) and the ceiling is clean. The manuscript is submission-ready as-is. NO EDITS REQUIRED -- a zero-edit result is a valid PASS. Do not manufacture changes. (WARNING: 1 gate artifact(s) had an unrecognised schema and were NOT counted -- this verdict may understate the floor: check_novel_schema)
