This illustration combines irregular spacing and changing chord sizes across different columns. It shows some of the kinds of variation measured by the technical proxy.

Open the diagram to view the full-size image. These are original timelines, not screenshots of a real map. Column numbers are not keyboard bindings. The example is illustrative rather than a test of the entire-chart classifier.

The v1 score combines column distribution, variation in chord sizes, timing-interval variation, and column imbalance. These are measurable signals, not an official technical skillset definition.

Use either form as an active player. The shared room’s future selections use the preference; already visible queue entries stay in place. Use .style or .map to inspect the current Mania chart and .pool for active filters.

A short drawing cannot establish a complete chart’s classification. Technical evidence can overlap Jack, Chordjack, Stream, and LN. Regular-looking passages can still be part of a highly varied chart.

When strict fresh choices run out, style fallback can broaden the selection while keeping the active eligibility boundaries. Common spelling aliases remain supported; see style syntax.

See the visual pattern atlas, the command reference, practical style examples, and style selection.

The illustration explains the pattern, not an automatic admission test. Current native catalogs require a style score plus sustained/prominent feature evidence; a short passage or isolated event need not qualify the whole chart. See style selection and fallback for combinations and fresh-map tiers.
