    "Resident steps repeat one host batch with transfers included; not device-only compute or an epoch schedule.",
    "Fit is a fresh-model single training epoch after resident process/device warmup; includes tracing/compilation, excludes validation, export and model build.",
    "RSS is process lifetime high-water memory, not stage allocation or device memory; no GPU memory measurement.",
    "Single observations, not a speedup claim. Use fresh processes and repeated runs for comparisons."
