# 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.

# pulls tzdata in as a dep, which otherwise blocks the build asking

# System deps (Ubuntu 22.04). Isaac Sim base may ship apt/pip configs
# pointing at NVIDIA-internal mirrors (urm.nvidia.com) that HF Spaces'
# build infra can't reach — wipe those before any install. The base
# default Python is 3.10; simready-validate requires >=3.11, so we
# install python3.11 from the deadsnakes PPA and use it explicitly
# for everything below.

# base image with a different name); we just use the path. HOME points
