# Code Simplification

## Rules

- Do not change behavior.
- Prefer small, safe steps.
- Add or update tests if coverage is missing.

## Workflow

1. Read the target code and identify complexity drivers.
2. Plan minimal refactors (early returns, extraction, deduplication).
3. Apply changes incrementally and keep intent clear.
4. Run relevant tests and linters.

## Heuristics

- Keep functions ~20 lines when possible.
- Limit nesting depth to 3.
- Reduce argument count to 4 or fewer.
- Replace magic numbers with constants.

## Report format
