Allow the sealed ResNet and YOLO convergence protocol to run unchanged on the remote NVIDIA accelerator while retaining CPU and MPS support.
Constraint: Preserve fixed seeds, exact workloads, and one-device-per-run semantics
Rejected: Reuse mixed MPS and CUDA results | invalid cross-device production matrix
Confidence: high
Scope-risk: narrow
Not-tested: Full production matrix on RTX 3080 Ti
