The new value type collided with DatReaderWriter.Types.Frame (used in physics-adjacent code like ShadowShapeBuilder), which the structural fix (per-file using-aliases across 6 files) would have re-incurred in every later physics slice. Renamed the TYPE to CellFrame; the Position.Frame MEMBER keeps retail's name. Restored the 5 alias-only files to their pre-Slice-1 state; synced spec + plan. Core 1522 passed / 0 failed.
