v0.1.0 — Blender agent OS + robot-arm demo

First public cut of the Blender agent operating system plus the robot-arm demo.

What's in the repo: Claude/Codex operating rules (AGENTS.md), three skills, a 28-file bpy knowledge base verified on Blender 5.2.0, the AGENT_OK/AGENT_FAIL execution contract (scripts/agent_runtime.py, headless-run.sh), state-safe verification helpers, a spec-driven production gate for 3D-printable parts, 30 boilerplates, 93 tests.

Robot-arm demo: accepted assembly film, source .blend, 38-part print kit (STL/3MF, PETG + TPU), engineering reports.

Gate evidence (2026-09-06): production-gate.py on the 38 exported STLs → GATE PASS, 836 checks pass, 0 fail (manifold, no self-intersection, one shell, dimensions = parts-list.csv ± 0.1 mm, STL round-trip). Report bound to scene/spec sha256 in builds/robot-arm-print-assembly/reports/gate-report-260906.json.

Not proven — read before printing for real: load capacity, fit after shrinkage, thermal/creep, retention hardware, wrist torque margin. Files are fit-prototype geometry; the arm is not released for manufacture.

Asset: robot-arm-print-kit-v0.1.0.zip — parts, plates, CSVs, README, gate report/spec, plate manifest, export check, two renders.
