Two root causes of cross-process non-determinism fixed: 1. MSE→C51 graph switch: graph_forward_mse and graph_forward were captured in different sessions with different cublasLtMatmul configs. Fix: always use blended graph_forward (c51_alpha controls blend). Deleted LossMode enum, graph_forward_mse, and all switching code. 2. Multiple capture sessions at steps 0-2: graph_forward, graph_ddqn, and graph_adam were captured individually before graph_mega at step 2. Each capture contaminated cuBLAS internal state. Fix: capture graph_mega at step 0 (single capture session). Result: runs with same initial cublasLtMatmul capture are fully bit-identical across all 30 epochs. Remaining cross-process variation is from the single initial cublasLtMatmul call during graph capture. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
