- Static-mesh scale test passes: 1 m = 100.00 cm, origin preserved, axis mapping east→+X / north→−Y / up→+Z (named presets ue_metric_v1 both sides). - MPFB 2.0.18 acceptance passes: generated human + standard 137-bone rig with weights + v2 skin baked to 1024² diffuse; imports as SkeletalMesh with Skeleton, Material, and Texture2D in /Game/Test/Character. - MPFB headless requires XDG_CONFIG_HOME at the Flatpak config tree; documented in Art/blender/README.md, probe in Tools/addon_compat_probe.py. - Docs/build.md completed: fresh-checkout build, packaging, headless checks. - Docs/setup.md reconciled with reality; ROADMAP/bootstrap closed out.
