# Contributing ## Before a pull request ```bash ``` Every command must exit `0`. ## Rules - One pull request, one logical reason. - New behaviour arrives with a test; a new check arrives with a fixture that fails without it. - Do not add dependencies without a discussion: . - Do not commit secrets, real domains, IP addresses or personal data. Use `example.com`, `203.0.113.0/24`, `user@users.noreply.github.com`. - Style: . ## Language of documentation English files are canonical; translations carry a language suffix (`README.ru.md`) and are updated in the same commit. ## Commit messages Conventional Commits: `feat:`, `fix:`, `docs:`, `perf:`, `refactor:`, `test:`, `chore:`. A breaking change is marked with `!` in the header or `BREAKING CHANGE:` in the body. ## Reporting a bug Include the version, the environment, the exact command, the exit code, and the output without secrets.
