Ghost Sweeper (Empty Cell Remover)

SCAN walks every saved scene cell and data packet and lists empty header-only cells, objects with two owners (a scene row plus a buffer/section-loader copy), ids saved twice, stacked duplicates, orphans and dead paths; type any id to see every place it lives. DELETE ALL EMPTY CELLS runs touch-then-delete behind an in-game confirm, and CLEAN SCENE SIDE cuts doubled rows. The bundled guide lists every fix path we tried on a 4.6 km crater, from cleanup to burying stale summaries under a raised solid floor (what finally worked), plus a log of the engine-side bugs. Build room only. A stopgap: the Spawn engine is already being updated to rebuild stale far views itself. After a cleanup, relog only once your version history shows every step saved.
