The PIMPL class StreamInletPrivate owns the QTcpSocket and is responsible for opening the connection to the host/port pair stored in the LSLLIB::stream_info, draining pending bytes on every samples_available probe, and reassembling them into fixed-width multichannel samples sized by channel_count * sizeof(float). Partial samples observed at the end of a readAll buffer are kept in a residual byte buffer and prepended to the next read so that no sample is ever split across calls.

The public LSLLIB::stream_inlet methods are thin forwarding shims that delegate to the PIMPL, which lets the public header stay free of Qt network symbols and keeps the std::unique_ptr destructor pinned to this translation unit where the complete type is visible.
