# SimReady Validator — HuggingFace Space image
#
# Base: nvcr.io/nvidia/isaac-sim:4.5.0. Ships Kit at /isaac-sim/ so
# runner._kit_available() auto-selects --use-kit and the validator
# runs PhysX / MDL rules without a code change.
#
# UID 1000 is required by HF Spaces. The Isaac Sim base already has
# a user at UID 1000 (varies between releases — ubuntu / kit / etc.),
# so we REUSE it rather than create one. /app is the workspace dir
# with HOME=/app so Claude Code CLI finds skills under ~/.claude/skills
# regardless of the existing user's name.
