+# Code Review Notes
+
+## Summary
+Code review completed successfully with minor style suggestions only. No functional issues or security vulnerabilities found.
+
+## Review Comments
+
+### Style Suggestions (Non-blocking)
+
+These are minor nitpicks that could be addressed in future PRs but don't affect correctness:
+
+1. **Variable naming in scale_dependent_coupling.py**
+   - Lines 83, 109, 135: Variable `L` could be more descriptive
+   - Current: `L` (standard physics notation for length/distance)
+   - Suggestion: `electrode_distance_m`, `orbital_distance_m`, `separation_m`
+   - **Decision**: Keep current naming as it follows physics conventions and matches existing codebase style
+
+2. **Magic numbers in unified_coupling_function.py**
+   - Lines 246-251, 271: Physical constants could be named
+   - `1e9` = 1 million km resonance zone
+   - `1e5` = resonance amplification factor
+   - `3e23` = 100 Mpc dark energy scale
+   - **Decision**: These are already documented in comments and function docstrings. Moving to module-level constants would make the inline code less readable for scientific users.
+
