Retired Sync Diagram Paths

The Mermaid diagram set was retired in July 2026 when the sync documentation was consolidated into the Sync Architecture Field Guide. These links route each old topic to its maintained replacement:

• Local persistence
• Server sync
• Conflict resolution
• File-based sync
• Meta-reducers and atomic intent
• Archive operations
• SuperSync vs file-based sync
• Sync flow explained

The individual retired filenames remain as forwarding stubs so historical links keep working.
