+// To be implemented:
+// 1. Define an OpenRPC schema for supervisor functions (e.g., server status, key rotation).
+// 2. Implement an HTTP/TCP server (e.g., using Axum or jsonrpsee) that serves the schema
+//    and handles RPC calls.
+// 3. Implement support for Unix domain sockets in addition to TCP.
+// 4. Use the `herocrypto` or `redis-rs` crate to interact with the main `herodb` instance.
