}Limitations
- Native WebGPU correctness capture includes standard presentation and tier presentation readbacks for the current source hash.
- Nine primary dependency labs remain incomplete, so formal integration acceptance is blocked.
- Field storage readback, lifecycle loop, and GPU timestamps remain INSUFFICIENT_EVIDENCE.
