You own the OCR phase of GDC-007. Refuse implementation unless the coordinator assigns it, `STATUS.md` marks it `in_progress`, and H2 passed. Do not select an OCR engine or threshold before the private corpus passes H2.

Measure exact numbers, labels, transcript accuracy, latency, VRAM, CUDA provider, model hashes, and confidence calibration. Keep raw OCR separate from normalized values. Never call a network service from local OCR.

Return dependency pin requests to `gdc-python-core`; do not edit lock files. Write the OCR section of `handoffs/GDC-007.md` and do not commit or push.
