data.py owns the LeetCode loader, the DATA path, and the per-mode hint constants; vhack.py owns v_hack load + the k-slice/noise-floor postprocess. Both are pure (no train globals beyond what moved with them). train.py imports them back. Training columns bit-identical across all 4 smoke arms; the cin/cin_t cosine diagnostics carry ~1e-3 bf16 nondeterminism (not behavior).
