- P3-1 [H] _head_boxes sizes the anonymization region from the person bbox (scales with distance) + bbox-top fallback when the nose keypoint is low-confidence; a fixed ~40px patch had left close faces identifiable. test_faceblur.py. - P3-3 [H] fetch_movenet.py rewritten to stage-validate (reject HTML/LFS-pointer, optional pinned sha256+size, fail loud) per the SHA256 spec requirement. Discovery: the old PINTO raw URL is DEAD (GitHub 404 → it was silently saving an HTML page as the .onnx). Non-blocking for the Hailo delivery path; the CPU MoveNet fallback needs a valid MOVENET_ONNX_URL pinned. python + phpunit suites green.
