🐛 fix(sync): resolve delete persistence regression and harden data-safety invariants (#13)
Deletions made in the UI were silently lost on page reload because the sync baseline (lastSyncedElementsRef) was never populated after initial load, making the delta algorithm unable to detect removed elements. Additionally, import_scene and restore_snapshot used a non-atomic clear+create pattern that could permanently lose all canvas data if the batch create failed after clearing, and duplicate_elements copied stale binding references pointing to original element IDs instead of remapped duplicates. 🔧 Sync baseline restoration: - Populate deletion-detection baseline on every server-to-client data path (page load, delta resync, hello handshake, initial elements broadcast) - Establish sync version and hash baselines to prevent phantom re-syncs 🛡️ Data-loss prevention: - Backup current scene before destructive clear in replace-mode operations - Atomic restore from backup when subsequent batch create fails - Remap all binding references (start/end IDs, boundElements, containerId) to new IDs during element duplication ✅ Comprehensive test coverage (154 new tests, 344 total): - Delta sync flows including deletion persistence and bidirectional sync - Multi-tenant element/sync/WebSocket isolation - Arrow binding resolution across all shape types and edge cases - MCP tool integration covering backup-restore and binding remapping - Input validation and security boundary testing - Frontend sync algorithm unit tests reproducing the exact regression 🎯 Eliminates the most critical data-integrity risks: deletions now persist reliably, destructive operations are rollback-safe, and the full test suite provides regression coverage for every sync path.
