name: Refs not closing
description: >-
  Refuse a pull request whose `Refs #N` promise contradicts GitHub's
  closing-issue graph (#218). GitHub recognizes closing keywords anywhere
  in a PR body, including ordinary prose and code spans; the action reads
  the graph once and lets a pure script decide whether any Refs target is
  already scheduled to close.
runs:
  using: composite
  steps:
