SuperSync Architecture Documentation Moved

The duplicated Mermaid architecture tome previously stored here was retired because its copied client flows, endpoint shapes, schema, and conflict behavior had drifted from the executable protocol.

Use these maintained owners instead:

• SuperSync Server Architecture — server-only trust boundary, stable endpoint purposes, transaction invariant, retention, E2EE, and executable owners.
• Sync Architecture Field Guide — five-minute whole-system maintainer map.
• Sync documentation index — focused client contracts and scenario catalogs.

This forwarding stub preserves historical links. The removed diagrams remain available in git history.
