## Google Python Style Guide

The vendored guide is background reference material only, not Vexcalibur's enforceable style policy. It contains upstream rules and links that intentionally do not match this repository, including `pylint`, 80-character line length, and formatter recommendations. Vexcalibur's project license remains Apache-2.0; this external document keeps its upstream license and attribution. The vendored Markdown is normalized to remove trailing whitespace and patch stale upstream-local links so repository checks remain clean.

Vexcalibur's canonical Python style policy is [docs/development/python-style.md](../development/python-style.md).
