+  #! Only this repository runs the weekly `schedule`. A copy of this workflow in any other
+  #! repository is scheduled independently by GitHub and would deploy into the same GCP
+  #! project, colliding on instance and disk names.
+  #!
+  #! The schedule guard means: "Run unless this is a scheduled event in the wrong repository."
+  #!
+  #! | Event           | Repository               | Guard |
+  #! |-----------------|--------------------------|-------|
+  #! | `schedule`      | `ZcashFoundation/zebra`  | true  |
+  #! | `schedule`      | any clone                | false |
+  #! | anything else   | any repository           | true  |
+  #!
+  #! The guard is on the three jobs that have no `needs:` — `build`, `get-available-disks`
+  #! and `get-available-disks-testnet` — so everything downstream skips with them, plus
+  #! `integration-tests-success` because it is `always()` and does not allow `build` to skip.
+  #! Guard any new job without `needs:`, and any downstream job whose `if:` can still be true
+  #! when its guarded dependencies are skipped, such as a job using `always()`.
+  #!
+  #! `workflow_dispatch`, `push` and `pull_request` are deliberately unaffected everywhere.
