Reaching maintainers

The CONTRIBUTING.md file documents the etiquette for tagging maintainers. For most non-trivial PRs, opening the PR and waiting for assign-reviewers.yml (.github/workflows/assign-reviewers.yml) to suggest reviewers based on touched paths is the right approach.

Issue triage

The team triages GitHub issues with labels described in ISSUES.md. For specific subsystems, the contributors above are typically the right pings.
