cuda-profiling
Use when profiling CUDA with Nsight Systems or Nsight Compute, reading roofline and occupancy metrics, or annotating phases with NVTX. Not for correctness: use cuda-debugging.

# CUDA profiling
## Contract
| Field | Bound contract |
|---|---|
| Trigger | A CUDA kernel or pipeline is slow or unexplained, and the job is timeline capture, per-kernel metrics, roofline reading, occupancy analysis, or NVTX annotation. |
| Authority | Reversible local. Writes are limited to profiler reports and logs under the project tree; rollback is deleting those files. No remote mutation. |
| Side effect | Report files (`.nsys-rep`, `.ncu-rep`, CSV), possibly elevated-privilege profiling runs, and a diagnosis. |
| Done | The bottleneck is named with a measured metric, and the recommended fix targets that measurement. |
## Inputs
1. Workload (required): the application or kernel to profile and one representative input.
