Remarks

Values map 1:1 to the request-SID bytes defined by ISO 14229-1:2020. Positive responses use the request SID plus 0x40 (per ISO 14229-1 §7.3). Negative responses are always framed as 0x7F, requestSid, NRC. The enum only covers the services the MVP client actually implements; unknown SIDs are still supported via the SendRawAsync(ReadOnlyMemory<byte>, CancellationToken) escape hatch.
