Viktor's standing instruction (2026-06-12): lean on external infra as
much as possible for CI — builds, running tests, lint, releases all on
GitHub Actions hosted runners, never on cluster nodes; in-cluster
pipelines only for cluster-touching steps (deploys, terragrunt,
certbot). Also: watch any triggered pipeline chain to completion and
fix failures immediately. Added to AGENTS.md + .claude/CLAUDE.md
CI sections (ADR-0002 companions).
