No, once a project is deleted in Phoenix, it cannot be restored, and all associated data is permanently removed. This applies even if you are using a dedicated PostgreSQL database鈥攄eletion is irreversible and the project, along with its traces and data, cannot be recreated or recovered through the UI or API as of current Phoenix behavior.
If you need to prevent accidental loss, consider implementing regular database backups at the PostgreSQL level, as recommended for production deployments, to allow for point-in-time recovery in case of accidental deletions. Would you like more detail on backup strategies or recovery options?
