- Replace flat JOINT_GAIN with per-joint JOINT_SCALE/JOINT_OFFSET linear mapping
for accurate retargeting (l_shoulder_pitch/roll/yaw, l_elbow calibrated)
- Switch shoulder parent from chest to hips to avoid head rotation contamination
- Add solo-joint mode (--solo-joint) for isolating single joints during testing
- Use XRHandTracker wrist transforms in body_tracker.gd for better wrist rotation
- Add joint_test.py for single-joint animation with pause-at-peak support
- Add joint_calibrate.py for XR-to-robot range calibration with scale+offset output
- Add calibration_log.md documenting extent tuning and axis mappings
- Disable waist/right arm/hands temporarily for left-arm-only testing

numpad overlay that appears when tapping input fields.

Adds a joint retargeting bridge that converts Quest 3 body tracking
data into G1 robot joint commands for Isaac Sim via CycloneDDS.
- Extend body_tracker.gd with 8 body joint transforms (56 floats)
- Extend teleop_server.py with body_joints_shared memory
- Add retarget_bridge.py: body retargeting, hand mapping, DDS publishing
- Add launch_bridge.py: one-command launcher for sim + bridge
- Update requirements.txt with unitree-sdk2py dependency

- Two-phase startup: CONFIG phase (VR start screen) -> AR phase (passthrough)
- Start screen with server host/port input, connect button, and launch AR button
- VR UI pointer with controller ray-pointing and hand poke interaction
- Body tracking visualization with colored spheres (spine, head, arms)
- Hand tracking with camera-based tracking (no controllers required)
- Android flavor manifest for Quest hand/body tracking permissions
- Upgrade OpenXR Vendors plugin from v3.1.2 to v4.3.0-stable
- Export presets updated for Godot 4.6.1 Meta plugin format
- Build scripts for Godot 4.6.1 with vendor plugin setup

- Bundle godotopenxrvendors addon (Meta, Khronos, Pico, MagicLeap)
for self-contained repo — no manual plugin download needed
- Remove stale editor_plugins section from project.godot
(GDExtension auto-loads via plugin.gdextension, not plugin.cfg)

Godot 4.3 project for Quest 3 that replaces the browser-based WebXR
teleoperation with a native app using XR_FB_body_tracking (70 joints).
Key advantage: chest-relative wrist tracking eliminates head-position
subtraction artifacts and decouples body rotation from arm control.
Godot app: body_tracker.gd, teleop_client.gd, webcam_display.gd
Robot server: teleop_server.py (WebSocket, replaces Vuer ~900→~250 lines)
Drop-in wrapper: native_tv_wrapper.py (compatible with teleop_hand_and_arm.py)
