-          "message": "fix: sticky notes validation - eliminate false positives in workflow updates (#350)\n\nFixed critical bug where sticky notes (UI-only annotation nodes) incorrectly\ntriggered \"disconnected node\" validation errors when updating workflows via\nMCP tools (n8n_update_partial_workflow, n8n_update_full_workflow).\n\nProblem:\n- Workflows with sticky notes failed validation with \"Node is disconnected\" errors\n- n8n-validation.ts lacked sticky note exclusion logic\n- workflow-validator.ts had correct logic but as private method\n- Code duplication led to divergent behavior\n\nSolution:\n1. Created shared utility module (src/utils/node-classification.ts)\n   - isStickyNote(): Identifies all sticky note type variations\n   - isTriggerNode(): Identifies trigger nodes\n   - isNonExecutableNode(): Identifies UI-only nodes\n   - requiresIncomingConnection(): Determines connection requirements\n\n2. Updated n8n-validation.ts to use shared utilities\n   - Fixed disconnected nodes check to skip non-executable nodes\n   - Added validation for workflows with only sticky notes\n   - Fixed multi-node connection check to exclude sticky notes\n\n3. Updated workflow-validator.ts to use shared utilities\n   - Removed private isStickyNote() method (8 locations)\n   - Eliminated code duplication\n\nTesting:\n- Created comprehensive test suites (54 new tests, 100% coverage)\n- Tested with n8n-mcp-tester agent using real n8n instance\n- All test scenarios passed including regression tests\n- Validated against real workflows with sticky notes\n\nImpact:\n- Sticky notes no longer block workflow updates\n- Matches n8n UI behavior exactly\n- Zero regressions in existing validation\n- All MCP workflow tools now work correctly with annotated workflows\n\nFiles Changed:\n- NEW: src/utils/node-classification.ts\n- NEW: tests/unit/utils/node-classification.test.ts (44 tests)\n- NEW: tests/unit/services/n8n-validation-sticky-notes.test.ts (10 tests)\n- MODIFIED: src/services/n8n-validation.ts (lines 198-259)\n- MODIFIED: src/services/workflow-validator.ts (8 locations)\n- MODIFIED: tests/unit/validation-fixes.test.ts\n- MODIFIED: CHANGELOG.md (v2.20.8 entry)\n- MODIFIED: package.json (version bump to 2.20.8)\n\nTest Results:\n- Unit tests: 54 new tests passing, 100% coverage on utilities\n- Integration tests: All 10 sticky notes validation tests passing\n- Regression tests: Zero failures in existing test suite\n- Real-world testing: 4 test workflows validated successfully\n\nConceived by Romuald Członkowski - www.aiadvisors.pl/en",
