# PMAT Lint Extreme Refactoring Progress

## Refactoring Heuristic

1. **Build First**: Ensure build compiles before moving to next file
2. **Fix Lint Errors**: Address all lint warnings in the file
3. **Apply Extreme Quality Standards**:
   - 80% test coverage minimum
   - Zero SATD (no TODO/FIXME/HACK comments)
   - Complexity < 20 for all functions
   - Complete implementations only (no placeholders)
4. **Document Progress**: Update this checklist after each file
