🔍 Duplicate Code Analysis Report

Analysis of commit 3b4c53f (HEAD → main)

Summary

Analysis identified 3 significant duplication patterns across the internal/logger and internal/server packages. Total estimated duplicated code: ~70–80 lines across 7+ files.

Detected Patterns

1. Identical withLock() Implementations – Severity: High – See sub-issue [duplicate-code] Duplicate Code Pattern: Identical withLock() in Logger Types #2908
2. Boilerplate initGlobal* / closeGlobal* Wrapper Functions – Severity: Medium – See sub-issue [duplicate-code] Duplicate Code Pattern: Boilerplate initGlobal*/closeGlobal* Logger Wrappers #2909
3. Authentication Error Handling Trio (log + runtime log + error response) – Severity: Medium – See sub-issue [duplicate-code] Duplicate Code Pattern: Auth/Guard Rejection Trio (log + runtime-log + error response) #2910

Overall Impact

• Total Duplicated Lines: ~70–80 lines (estimated)
• Affected Files: 7 files
• Maintainability Risk: Medium — any change to lock strategy, global logger lifecycle, or auth error format must be applied in multiple places
• Refactoring Priority: Medium — Patterns Configure as a Go CLI tool #1 and Lpcox/initial implementation #3 are low-risk, high-value quick wins

Next Steps

1. Review individual pattern sub-issues for detailed analysis
2. Prioritize refactoring based on severity and impact
3. Begin with Pattern Configure as a Go CLI tool #1 (lowest risk) and Pattern Lpcox/initial implementation #3 (quick win)
