The first batch was 37,141 patches in 57 s of measured GPU time. The page reads the covered windings from the manifest, so its text updates as windings are added. The 9.362 µm scan is about four times coarser than the 2.4 µm one, so this layer is noisier. `w047` and `w050` ran with patch overlap 0.5; others ran with 0.25 or 0.2, and their 128 px patch grid shows as faint square tiles. Per-run records (checkpoint sha256, villa commit, requested and measured GPU seconds) are in `data/gpu/receipts/`; `data/gpu.json` is the summary the page reads.
