charter hackathon-2026q3

Mini-Hackathon — 2026-Q3

A short, focused competition for ML-for-OPC and ML-for-ILT models against a frozen test split, scored by the same MRC/DRC-gated leaderboard CI that powers the open board. Crown the SOTA on a fixed contract — not on whatever everyone happened to evaluate against.

Frozen Contract
