# Section 04 Code Review Interview

## Triage Summary

| # | Finding | Severity | Decision |
|---|---------|----------|----------|
| 1 | Negative line numbers | Medium | Auto-fix: explicit isinstance+<=0 check |
| 2 | line: None not tested | Low | Let go — covered implicitly |
| 3 | Truthiness fragile | Medium | Auto-fix: same fix as #1 |
| 4 | Note string not asserted | Low | Let go |
| 5 | Missing/non-list errors | Low | Let go |
| 6 | Existing tests | Info | Let go |

## Auto-fixes Applied

### Fix #1/#3: Replace truthiness check with explicit type check
Changed `if not line` to `if not isinstance(line, int) or line <= 0`.
This correctly handles negative line numbers, None, missing keys, and non-int types.

## Fixes to Apply
Auto-fixes already applied. No user interview needed.
