The full review
Stopped by us. Stopped by us (box row cap reached (2890s); stopped by the box lane so the run ships as partial); not a model failure.

The exact prompt
as run, 926 characters. Every result for this prompt
Using Blender's Python API only (a script run headless with blender -b -P), build a humanoid character with an armature (hips, spine, neck, head, arms with elbows and hands, legs with knees and feet) skinned to a simple stylised body mesh, and animate a seamless looping walk cycle of 32 frames at 24 fps. The walk must look human: knees and elbows bend one way only within realistic joint limits, feet plant with no sliding during contact, the pelvis bobs and the torso stays upright, and arms swing opposite to the legs. Add a three-point light and a camera. Render a 1280x720 PNG still of a mid-stride frame to render.png, render a turntable video to turntable.mp4 (the character walking in place while the camera orbits once around it, 1280x720, 24 fps, at least 4 seconds), save scene.blend, and export walk.glb with the armature and the walk animation (no cameras or lights). Write everything into the working directory.

Run notes
- frozen prompt (written): prompts/blender_humanoid_walk_cycle.md verbatim (Blender variant of humanoid_motion_cycle, 2026-09-30)
- plain wave-1-equivalent cc_config copy (settings.json + .claude.json; no ECC files)
- W6: Blender 5.2.2 GUI on a private Xvfb display inside the sandbox (filesystem socket in the sandbox's own /tmp only, per-run cookie), software OpenGL (llvmpipe), render threads 2; working directory = the run's work dir
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Context setting: 1M ([1m] model name)
- Isolation audit: outside paths seen
