primary path - CRITICAL: PR openai#1351 (Discriminative TTT, 1.0807) self-closed by author on 2026-04-05 — pre-quant AdamW TTT ruled as pre-eval adaptation on val data. Removed pre-quant TTT from technique table and plan. - Updated strategy to PR openai#1334 (Depth Recur + Parallel Residuals + MuonEq-R, 1.0897) as primary architecture target — zero legality flags. - Logged new PRs: openai#1379 (0.4162, n-gram mixer), openai#1376 (0.7094, SLOT-24 + pre-quant TTT), openai#1364 (1.1025, pre-quant TTT at risk), openai#1370 (1.003, GDN). - SLOT and pre-quant TTT both blocked; discriminative TTT post-quant still legal. - Updated CLAUDE.md Competition Strategy + Technique Reference + Lessons (v9.0). https://claude.ai/code/session_01RTLvTuYBp9YMtudwrY8mYM
