// ptt-upload tests focus on the fingerprint (fast-upload) path: the
// regular load path goes through ffmpeg's silk encoder + the OS temp
// directory, which we don't want to exercise in a unit test. The
// fingerprint path covers most of what makes ptt-upload distinct
// (group/c2c requestId difference, command id mapping, the group-only
// bytesGeneralFlags blob, voiceFormat honouring).
