# backend-integration lives in its own manual workflow
# (.gitea/workflows/backend-integration.yml) rather than running here. It held
# the runner for 3h12m on 2026-08-18 — 87 seconds of tests followed by a hang
# after the run completed — and blocked frontend-e2e behind it for the same
# three hours. Run it from Actions before merging anything that touches the API
# or the database.

  # Fails only on the rules with real defect-catching value — unhandled
  # promises, hook dependencies, missing alt text. Everything else is a warning
  # and does not block, which is why no --max-warnings flag appears here:
  # ESLint exits non-zero on errors and zero on warnings on its own. The split,
  # and the measurements behind it, are in
  # docs/superpowers/specs/2026-08-19-eslint-design.md.
