====== Stream patterns ======

A stream-like passage is a dense run of single-note starts. This example moves between columns at regular intervals.

===== Read the example =====
{{:images:patterns:stream_4k.png?640|Dense single-note starts moving between columns. Earliest events are at the top; time increases downward.}}

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.

===== What the analyzer measures =====
The broad v1 analyzer measures closely spaced single-note events and run length. It does not require a fixed alternating-column pattern, so repeated-column passages can contribute too.

===== Choose this preference =====
<code>
.style stream
.stream
</code>
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.

===== Limitations =====
The human description “stream” can be more specific than this heuristic. Rhythm, speed, length, and other structures still vary; this is not a stamina classification.

When strict fresh choices run out, [[wiki:style_fallback|style fallback]] can broaden the selection while keeping the active eligibility boundaries. [[updates:v6_6_17|Expanded spelling aliases]] are supported in the confirmed live v6.6.17 release.

===== The same idea in 7K =====
{{:images:patterns:stream_7k.png?640|Single-note starts spread across seven columns; time increases downward.}}

The structural idea also applies in 7K. The room keeps its key mode; selecting Stream does not convert a 4K room into 7K or change the player’s bindings.
