At camdkit 0362321d the OpenTrackIO protocol version constant is 1.0.1 (the only GitHub release is v1.0.0 per producer, so pin the commit); pose rotation is intrinsic ZXY Euler in degrees with Y forward, which differs from USD/glTF axis conventions.

At camdkit 0362321d the OpenTrackIO protocol version constant is 1.0.1 (the only GitHub release is v1.0.0 per producer, so pin the commit); pose rotation is intrinsic ZXY Euler in degrees with Y forward, which differs from USD/glTF axis conventions.

Curator qualifications: Four timing representations, camera/lens field list, transport defaults (multicast 239.135.1.x, port 55555) and absence of USD/glTF/OTIO mappings (F1, F2, F5, F6) not reinspected; Unreal compatibility claims are unverified third-party statements. No quaternion field claim (transform_types.py) not re-read. Static reading only; no tracking data sent or received; no calibration converted.

Limitations: Static reading only; no tracking data sent or received; no calibration converted.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
