Vaccine: - Replaced upload_batch_gpu (sync DtoD) with upload_batch_ptrs_6 + submit_indirect_upload_ops (async indirect kernels). Zero sync. - Deleted upload_batch_gpu entirely — no callers remain. Causal intervention: - Removed entirely from hot path. Was running 14 cuBLAS forward passes every 100 steps with no readback and no training decision based on the result. Pure GPU waste. - Kernel still exists in cubin for future offline analysis. Causal readback: - Removed stream.synchronize() + memcpy_dtoh from run_causal_intervention. Return value was already discarded by caller. Now returns 0.0 immediately. Sensitivity stays on GPU. Dead code: - Deleted upload_batch_gpu (72 lines) — replaced by indirect upload. Per-step hot path on step 2+: 9 graph replays (~45µs) 5 async HtoD (92 bytes, ~5µs) Zero sync. Zero DtoH. Zero alloc. Zero CPU compute. Zero concerns.
