## False Positives
| Issue | File:Line | Reasoning |
|-------|-----------|-----------|
| serializeRequest 10 sequential conditionals | openai-codec.ts:442-503 | Each branch is 2-4 lines with a named field, no nesting. Reviewer noted "low urgency since each branch is trivially understandable." After other extractions reduced file cognitive load, this function reads clearly as a straightforward mapping. |
| File lengths (translation-proxy.ts 603 lines, openai-codec.ts 586 lines) | Both files | Addressed indirectly by method extractions — both files reduced well below 500 lines after COMP-1/2/3/4/5 fixes. No further action needed. |
