sending is temporarily paused: the kill-switch state is not yet loaded; retry shortly. This is an HTTP 503: a dependency is unavailable right now.

## Troubleshooting

- This is an operational or capability refusal, not a malformed request; the same call may succeed later.
- For a pause, honour `Retry-After`; for a capability refusal, send a part type the recipient’s device announced.
