+  # Replaces vyos/vyos-1x:.github/workflows/pr-auto-close.yml, which only
+  # covered `sagitta`. Closes every PR (including Mergify-created
+  # backports) opened against `sagitta`, `crux`, or `circinus` in any
+  # vyos/* repo that extends this config, except the two excluded below.
+  #
+  # Excluded repos:
+  #   - vyos-documentation — still accepts per-branch docs maintenance
+  #     and backports to `sagitta` and `circinus`.
+  #   - vyos.vyos — Ansible Galaxy collection on `main`; listed
+  #     defensively so a future branch named `sagitta`/`crux`/`circinus`
+  #     would not be auto-closed.
+  #
+  # Mergify's `repository-name` attribute is the bare repo name (no
+  # org prefix). Since this central config is consumed only by vyos/*
+  # repos via `extends: mergify`, the bare name is unambiguous.
+  #
+  # Backport interaction: the `defaults.actions.backport` block above
+  # creates backport PRs targeting whatever branch a Maintainer asks
+  # for. If a Maintainer issues `@Mergifyio backport sagitta` on a
+  # vyos/* repo other than the two excluded ones, the backport PR is
+  # created and then immediately closed by this rule. That is the
+  # intended behavior — backports to EOL branches are not accepted.
