# ProtocolPausingPolicy

* **Purpose:** Allow protocol-level operators to pause actions across all nodes simultaneously.
* **Guarded selectors:** Same set as `NodePausingPolicy`.
* **Config:** Registry owner whitelists protocol pausers via `add(users)` / `remove(users)`. Whitelisted accounts can pause/unpause selectors or trigger a global pause with the corresponding functions (no per-node scoping).
* **Behavior:** Reverts with `GlobalPause()` when globally paused or `SigPause(selector)` when that selector is paused.
