cuda-debugging
Use when debugging CUDA with cuda-gdb or Compute Sanitizer, reading GPU core dumps, using device printf, or triaging error codes 700, 701, 702, and 719. Not for performance: use cuda-profiling.

# CUDA debugging
## Contract
| Field | Bound contract |
|---|---|
| Trigger | A CUDA program crashes, hangs, or returns wrong values, and the job is interactive GPU thread inspection, automated memory and race checks, core dump analysis, device printf, or runtime error triage. |
| Authority | Reversible local. Writes are limited to debug builds, sanitizer logs, and core dumps in the project tree or `/tmp`; rollback is deleting those files and rebuilds. No remote mutation. |
| Side effect | Rebuilt binaries, sanitizer reports, core dump files, and a triage verdict. |
| Done | The defect class is named with evidence: a sanitizer report, a thread-level observation, or an error-code diagnosis, and the fix location is identified. |
## Inputs
1. Symptom (required): crash, wrong values, hang, or timeout, and when it appears.
