- httpRecorder: use http.NewRequestWithContext instead of http.NewRequest - tcpRecorder: loop Write to avoid short-write data loss - fileRecorder: guard against nil out in Record and Close - plugin/grpc, plugin/http: handle json.Marshal errors instead of ignoring - fileRecorder, redis*Recorder: idempotent Close via sync.Once - All exported symbols: add doc comments
