RE correction: op 0x1f7's worker gfx_registry_erase_range (@0x47d8b0) loops gfx_registry_erase over [handle, handle+count) — a teardown, not a create. Objects are created lazily by the geometry SET ops (gfx_object_get_or_create). GfxState.EraseRange + VM case + tests; opcodes.toml renamed gfx-elem-create -> gfx-elem-erase; Ghidra handler + workers annotated. Booted SC0000 CG geometry unchanged for the working CGs (no regression). Engine 40 green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
