Un-ignored: the dev drive is the ground truth the restoration and emulator work constantly reference (DPL3/LIBDPL + VRENDER i860 renderer source, BT/RP live+dev game trees, VGL_LABS pod boot, scene/audio content). Kept in-repo for the pod-owner community. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
