  # pull_request (not pull_request_target) — fork PRs get a read-only
  # token, so the label call 403s; the script catches that and stays
  # green (the original comment claimed the 403 was silent, but nothing
  # caught it, so fork PRs got a red check — e.g. #4872). Intentional
  # no-op on forks: the advisory label is only meaningful for
  # internal-branch PRs anyway.
  pull_request:
    types: [opened, synchronize, reopened]

# No concurrency group — intentionally omitted.
# Previous attempt (#3554, reverted #3599) used cancel-in-progress which
# killed in-progress PR runs before they produced useful results.
# Future iteration could safely add concurrency for scheduled/push-only
# triggers (where head_ref is empty and runs get unique groups).
