Combines NewTest (PR openai#841 base) with SOTA experiments that achieved ~1.12 BPB: - train_seq_len/eval_seq_len: 2048 → 4096 (long context from user's SOTA exps) - bigram_vocab_size: 3072 → 2048, bigram_dim: 112 → 128 (proven SOTA settings) - xsa_last_n: 11 → 4 (from user's best experiments) - gated_attention + value_residual: enabled by default (PR openai#824/838 show ~0.018 BPB improvement) - Bank QAT: symmetric int6 STE fake-quant on all weight banks during warmdown - Fix: CastedLinear QAT clip range (-32,31) → (-31,31) to match export format - Compression: lzma-6 → zstd-22 (PR openai#824/838: 14.9MB vs ~16MB, critical for fitting under limit) - Fix: target_mb budget uses decimal MB (1e6) not MiB (1024^2) matching competition rules - Budget-aware ±1 weight pruning retained from NewTest
