UCL + Huawei Noah's Ark just dropped Memento 3 — claims it maxed out ARC-AGI-3 public benchmark

How it works:
• Keeps LLM frozen, builds a self-improving rulebook as it plays
• Cleared all 25 public games using 44% fewer actions than human baseline
• Paper shows Claude Opus 5 scored 40.7 mean on same test

Catch: Results are self-reported. No verification on ARC Prize's private test set yet.

If this holds up on private eval, we're watching AGI scaffolding get real. If not, just another lab flex that doesn't ship.
