# Pythonic Design Pattern Application

Capture before/after evidence with mechanical-delta proof when a Pythonic-pattern rewrite is applied. Pair with `pythonic-design-pattern-detection`.

Every evidence file names the local Python example witness from `design-patterns-en.zip` and records the role map that the rewrite collapsed or preserved.

## Quick Start

```bash
uvx xenon --max-absolute C --max-modules C --max-average C src/
uv run gz arb step --name unittest -- uv run -m unittest -q
```

Author an evidence file under `.gzkit/chores/pythonic-design-pattern-application/proofs/application-YYYY-MM-DD-HHMMSS-<short-slug>.md` per the CHORE.md template.
