• MotleyAI/slayer#141: Both PRs modify the project's public Discord invite wiring in the same files—README.md, docs/index.md, and pyproject.toml—so the main PR's invite URL update is directly connected to the retrieved PR's addition of the Discord community link.

Poem

🐰 A Discord link hops from place to place,
Through README, docs, and config's space,
All pointing true to the same invite door,
The warren grows, we welcome more! 🎉
