Nothing in the server writes or reads a packet by hand any more, so the helpers for doing so go: - CBITSTREAM, CMSGHEADER, CINSTREAM, CINSTREAM_SKIP_HEADER, SEND_PACKET, SEND_PACKET_BROADCAST and HEADER_SIZE leave dCommonVars.h; - the free BitStreamUtils::WriteHeader (LUBitStream::WriteHeader writes the same bytes) and the unused PacketUtils::SavePacket are deleted. The last raw reads are replaced: WorldServer builds its input stream directly, the master packet logs read the header with LUBitStream::ReadHeader instead of peeking at packet->data[1] and [3], and MessageInspector reads a sent game message's header with the new NetGameMsg::ReadPacketHeader (the counterpart of WritePacket) instead of memcmp/memcpy. packet->data[0] is still compared with RakNet's own connection IDs. The frozen oracles keep using the macros verbatim through the test-only tests/dGameTests/LegacyPacketMacros.h; the HeaderSkip tests, which only tested CINSTREAM_SKIP_HEADER, are removed. docs/PacketArchitecture.md: "where we are" now describes the final state and what still touches raw bytes (RakNet IDs, replica headers, behavior bit streams), and a new section collects the known wire discrepancies found during the conversion, with client addresses.
