# OpenMHC leaderboard — HF Docker Space (self-rendering website).
# Computes the imputation leaderboard live from the OpenMHC-leaderboard-data
# HF dataset and serves it as HTML on $PORT (HF Spaces default 7860).
# Requires an HF_TOKEN secret with read access to the (private) dataset.

# Canonical point-flow reducers (skill / rank / fair skill) for both the
# imputation (Track 2) and forecasting (Track 3) leaderboards. Installed WITHOUT
# deps so the heavy base deps (torch, xgboost, ...) are skipped — only the slim
# runtime set in requirements.txt is used. Pinned to a commit (current main
# HEAD) for reproducibility + reliable Docker-layer cache busting; bump this
# when the reducers change. main@991caf5 adds the unified forecasting per-user
# substrate reducers (PR #35).
