Playable table (hinge-motor flippers, plunger, bumper, drain) plus a headless probe harness that measured, per engine: tunneling of a fast ball through a 1 cm wall with CCD off/on, and hinge-motor drive. Findings in godot/README.md: Box3D never tunnels even with CCD off, but its hinge motor sign is inverted vs Jolt/GodotPhysics, and Jolt blows through angular limits that Box3D holds. Ships a from-source macOS arm64 libgodot-box3d.dylib (upstream has no releases). Also gitignore the remaining Microsoft media at repo root. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
