Dropped QAT: 8% throughput penalty kills 600s budget (per PR openai#360). Three novel additions on thwu1 SOTA base (1.1428): - TrigramHash(20480, dim=32): trigram embedding signal, bigram 10240->4096 - XSA: orthogonal self-value removal, last 4 layers, from PR openai#287 - TTT: 3-epoch SGD on val tokens before eval, all ranks, ~47s budget Fixed rank bug: TTT runs on all 8 ranks independently (not rank 0 only) Artifact: ~15.64MB. Smoke tests passing. H100 validation pending.
