Open-source MuseScore plugins

Open-source work in the MuseScore ecosystem: MuseScore 4 plugins that bring Git-backed collaboration into ordinary score editing.

The heart of it is structural merge logic—measure-level longest common subsequence (LCS) on score XML—so two divergent versions become an in-editor visual diff you reconcile in notation. Around that pipeline sit PowerShell, batch, and Git worktrees for extraction, review, and push.

Implementation Notes

Published as open source so MuseScore users can adopt Git-backed scores without leaving the notation tool
Implemented merge logic with LCS alignment at measure granularity over score structure for stable, notation-native diffs
Generated a reviewable diff score inside MuseScore and a write-back path into .mscz after reconciliation
Connected QML plugin actions to Git worktrees, archive handling, and the XML/LCS pipeline end to end
