Export NVIDIA Nsight Systems `.nsys-rep` or `.qdrep` reports to native Nsight Parquet tables, then use the published Rust and Apache DataFusion converter to create Perfetto/Chrome Trace JSON and aligned event Parquet. Use when Codex needs a fast, SQLite-free conversion of Nsight CUDA kernel, H2D/D2H/D2D memcpy, CUDA Runtime launch, and NVTX timelines; CPU-API-to-GPU flows; Perfetto-compatible JSON without tokenizer failures; process-aware multi-device tracks; or outputs under `$HOME/.nsys-workspace/REPORT_NAME/`.
