}

Required Methods

fn server_configuration( &self, ) -> Result<Option<StoredServerConfiguration>, StorageError>

The stored copy, or None when this database has never held one.

fn store_server_configuration( &self, identifier: &str, backend_url: &str, response: &[u8], fetched_at_ns: i64, ) -> Result<(), StorageError>

Write the copy whole: identifier, URL, response, and fetch time. Never touches conflicting_identifier, so a matching refresh cannot erase a recorded conflict (CFG-053).

fn record_server_configuration_conflict( &self, conflicting_identifier: &str, ) -> Result<(), StorageError>

Record that the deployment answered with a different identifier (CFG-051). Does nothing when no row exists yet.
