Hydro Contest OS

2025 season environment

The 2025 image adapts the ICPC World Finals Programming Environment and is repackaged for deployment and onsite operations at contest venues in China.

Data safety note: The 2025 image includes the CLI Deploy Toolkit. Its default boot entry may rebuild the first available disk. Do not boot it on a machine containing personal data; use contest-dedicated hardware or a virtual machine.
