+# Automatic repo-config migrations for Dependabot PRs
+#
+# The companion auto-dependabot workflow skips repo-config group PRs so
+# they're handled exclusively by the migration workflow.
+#
+# XXX: !!! SECURITY WARNING !!!
+# pull_request_target has write access to the repo, and can read secrets.
+# This is required because Dependabot PRs are treated as fork PRs: the
+# GITHUB_TOKEN is read-only and secrets are unavailable with a plain
+# pull_request trigger.  The action mitigates the risk by:
+#   - Never executing code from the PR (migrate.py is fetched from an
+#     upstream tag, not from the checked-out branch).
+#   - Gating migration steps on github.actor == 'dependabot[bot]'.
+#   - Running checkout with persist-credentials: false and isolating
+#     push credentials from the migration script environment.
