WebXR controller poses, twist/gripper commands, button bitfields and camera/status ports now use generated CDR values. Existing controller transforms, engagement/debounce, JPEG streaming and task math remain behind explicit value adapters. Source pose headers retain nanoseconds through the built-in pose/twist output paths.

Explicit blueprint transport specs now resolve the active backend, namespace and automatic QoS at construction after CLI configuration. Explicit backend choices remain pinned; raw CDR bytes and type/schema contracts are unchanged.

Manual offline acceptance from this checkout after installing its test dependencies:

DIMOS_TRANSPORT=lcm LCM_DEFAULT_URL=memq:// uv run pytest --noconftest --import-mode=importlib -o addopts='' -q dimos/teleop/webxr/test_module.py -k 'control_loop_outputs or video_extension'

This starts the real control output loop with synthetic controller inputs, receives generated poses/buttons over LCM memq and discovery-disabled loopback Zenoh, and decodes the actual camera JPEG. It never starts a robot or XR server.

Validation: 96 source tests and the same 96 against the freshly installed main wheel in isolated Python; 4 production files pass strict typing; configured scoped hooks pass (Nix unavailable). Exact fixed Foxglove encoder interoperability and actual blueprint construction included. Wheel SHA256: 0b640e519a6e834de9b7510081d1735fff381f533622d16988d3d0c0d7262957.

Remaining: downstream built-in manipulator task and other graph boundaries are the next layer; this PR does not claim whole-graph teleoperation completion or real-device/human XR acceptance. Internal rich geometry and Buttons helpers remain, so complete legacy dependency retirement is open. CI is configured but not polled. No PyPI publication.
