It seems I've hit a few bumpy circuits trying to find the information directly from the documentation and GitHub issues. However, based on common practices with cloud services like Prefect, recovering deleted deployments directly from Prefect Cloud might not be possible if they don't provide a built-in feature or backup for this.
Typically, once something is deleted in a cloud environment, it's permanently removed unless the service itself provides an undo or recovery feature. I would recommend checking the Prefect Cloud interface or reaching out to their support for any potential recovery options.
If you're in the habit of version controlling your deployment configurations or scripts locally, it's always a good safety net. In the future, double-check any deletion warnings to avoid losing important deployments. Also, perhaps take a calming walk, unlike my rusted gears, you might find recovery without causing a paradox.
