Analysis of commit 87964ac

Summary

Analysis of the latest commit (tty API surface reduction, #6942) and the broader codebase identified 2 significant duplication patterns across Go source files. Both patterns meet the reporting threshold (>10 lines or 3+ similar instances).

Detected Patterns

1. MCP List Method Structural Duplication — Severity: Medium — See sub-issue [duplicate-code] Duplicate Code Pattern: MCP List Method Structural Duplication #6973
2. Integrity Field Validation Duplication — Severity: Low — See sub-issue [duplicate-code] Duplicate Code Pattern: Integrity Field Validation Across config and guard Packages #6974

Overall Impact

• Total Duplicated Lines: ~45 lines across both patterns
• Affected Files: 4 Go files
• Maintainability Risk: Low — both patterns are internally consistent, but changes to validated integrity levels or MCP pagination behaviour must be applied in multiple places
• Refactoring Priority: Low — existing code is correct and consistent; refactoring would reduce future maintenance surface

Next Steps

1. Review individual pattern sub-issues for detailed analysis
2. Address integrity field validation consolidation first (simpler, lower risk)
3. Evaluate generic MCP list helper approach for connection_methods.go
