 - Add delta-sync protocol scaffolding and an auditable reconciliation log
 
 This work aligns with the roadmap described in AGENTS.md and is designed to be extended incrementally.

+- Test status: 9 tests passing locally; packaging build succeeds via test.sh.
+- Ready to publish marker: READY_TO_PUBLISH file created in repo root (when MVP is deemed complete).
 CatOpt Bridge (MVP)
 - The CosmosMesh MVP includes a minimal CatOpt-style bridge that maps local optimization primitives
   to a canonical representation suitable for cross-domain adapters. This scaffold provides:
