MÖBIUS 0.3.16 - Windows preview

Adds configurable Session lineage previews and validates a multi-Session drag-demo workflow. Graphs now support horizontal or vertical layout, compact nodes, optional native IDs and source status, persistent preview preferences, clearer counts, search focus, ancestor highlighting, and all five Harness targets. The installed package passed a five-Session, four-handoff, three-round lineage test plus project-private Skill install/edit/isolation/uninstall acceptance.
