# Generic GPU runtime base image for Foxhunt training pods
# Contains: CUDA 13.0 + NVRTC + rclone (no cuDNN — zero conv ops in codebase)
# Binaries are fetched by initContainer at pod startup, not baked into this image.
# Rebuild: only on CUDA version bump

# Plan 5 Task 3 (A.4.1): nsys profile harness.
# `nsight-systems-cli` is installed unpinned because the CUDA 13 runtime base
# already pulls in the nsys version that matches its NVRTC stack; pinning a
# stale apt version (e.g. 2024.4.1.61-1 from older plans) causes the build to
# fail when the apt index advances. Verify post-build with `nsys --version`.
