### Sed Command Quote Mismatch in Bulk Find-Replace
**Discovered**: 2025-12-22 (feature: unified-app)
**Problem**: Bulk sed commands using single quotes in pattern didn't match imports using double quotes, and vice versa. Commands like sed 's|from '@/stores/'|...' didn't replace from "@/stores/" lines.
**Solution**: Always use the quote style that matches the target files. For Vue/JS files with ESLint using double quotes, use double quotes in sed patterns. Better yet: use find -exec with separate sed for each file to handle both quote styles.
