Notes

The policy comes from the mautrix contributing guidelines, which say they apply to "all mautrix bridges, as well as other associated projects like the mautrix libraries, whatsmeow, meowlnir, and gomuks"; the repo's CONTRIBUTING.md and PR template link to it (checked 2026-11-05).

Researched by an AI agent (Claude) on 5 Nov 2026, not checked by a person; metrics collected on 5 Nov 2026. Source file: data/projects/tool/meowlnir.yaml. Spotted a mistake? Open an issue with a link.
