// Transmission's own field names, casing warts and all (`percentDone` beside `peer-limit` and
// `sequential_download`). Renaming them here would mean this file and Transmission's rpc-spec.md disagree
// on what a field is called, which is exactly the confusion you don't want at 2am.
//
// The `officer*` fields are the sidecar's own additions — see src/servers/sidecar/transmission/rpc.ts.
