SecureFsWriter writes through tokio::fs::File, whose write_all() only enqueues a blocking write task (tokio's poll_write returns Ready before the write completes), so the data may not be visible yet when the test reads the file. Drop the race-prone content assertion and only verify the Unsupported contract.
