Reproduction of PR openai#803's complementary training approach on 8x L20Z (H100). Two-seed validation: 0.4377 (seed=1337), 0.4380 (seed=42). Key: bigram-weighted loss reweighting (COMPLEMENT_ALPHA=0.5) trains the neural model to specialize on tokens n-gram caches can't predict, combined with BackoffNgramMixer (orders 2-10) and legal score-first AdamW TTT.
