Staff arm a packet capture on the dashboard; master passes MESSAGE_CAPTURE_CONTROL ARM to
every world, auth and chat and arms its own. Each server's PacketCapture tap (dServer receive,
and a send hook in RakPeer::Send so replica constructions are seen too) records into one
preallocated chunk per server and ships sealed chunks through master on the main loop when
capture_flush_bytes or capture_flush_interval_ms is reached; past capture_buffer_max_mb the
oldest chunks are dropped and the dashboard records a gap. Nothing is armed: one flag check.
- targets: an account (from its login; packets before the login are kept per connection
and added once auth or the world knows whose they are), a character (from when it is
picked), or everything; up to 8 at once (a bit each in the record mask)
- worlds and auth record their clients' packets and the master link messages of a captured
player (session keys by name, zone transfers by request, player added/removed, migration);
chat finds the player in each packet; master records server traffic for everything
- secrets are never recorded: structs that carry them (login request, login response user
key, world validation session key, session key messages between servers) are read,
blanked and written again before recording; auth keeps only the handshake and login
- PacketDecoder: a registry by service and message id names every packet and decodes the
registered structs; CaptureBundle is the file format (DLUBNDL1, metadata, records);
CaptureTools orders records on one timeline, pulls movement out, makes bundles portable
or anonymous and diffs replays
- the dashboard keeps packet captures in message_capture_sessions (capture_kind 1) and
their packets in a file under capture_dir, one write per batch; arming is audited
- MESSAGE_CAPTURE_CONTROL/DATA only gain appended enum values and trailing fields

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.

Every packet of the chat service is now an LUBitStream struct in dNet/ChatPackets.h
(docs/PacketArchitecture.md, PR 13), and nothing in the chat server or the chat side of
the world server reads or writes a packet by hand any more.
- World <-> chat: LoginSessionNotify, UnexpectedDisconnect, GMLevelUpdate, GMMute,
Announcement (GM announce), CreateTeam, TeamUpdate (TEAM_GET_STATUS to worlds),
AchievementNotify, ShowAllRequest, FindPlayerRequest.
- Client -> world -> chat (friends, ignore list, teams, general and private chat):
GetFriendsList, AddFriendRequest, AddFriendResponse, RemoveFriend, GetIgnoreList,
AddIgnore, RemoveIgnore, GeneralChatMessage, PrivateChatMessage, TeamInvite,
TeamInviteResponse, TeamLeave, TeamKick, TeamSetLeader, TeamSetLoot, TeamGetStatus.
The 77 bytes the handlers skipped are named fields now (the sender block the client
fills in); the 4 unused bytes after the player ID are kept as `unknown`.
- What the client receives. Chat service (ChatPackets::Client): GeneralChatMessage
(replaces SendChatMessage; SendSystemMessage stays as a helper built on it),
PrivateChatMessage. Client service (ClientPackets, as structs go in the file of the
ServiceType in their header): SendCannedText (replaces SendMessageFail), GetFriendsListResponse, AddFriendRequest,
AddFriendResponse, RemoveFriendResponse, UpdateFriendNotify, WhoResponse,
ShowAllResponse, Get/Add/RemoveIgnoreResponse, TeamInvite, TeamInviteInitialResponse,
and the team game messages chat writes (TeamInviteConfirm, TeamGetStatusResponse,
TeamSetLeader, TeamAddPlayer, TeamRemovePlayer, TeamSetOffWorldFlag) as TeamGameMsg
structs, since chat doesn't link dGame's NetGameMsg.
- WORLD_ROUTE_PACKET is ChatPackets::WorldRoutePacket (its own file, dNet/WorldRoutePacket.h,
since it carries packets of other services): the target and the inner packet.
ChatPacketHandler::SendRouted replaces the per-function route headers and
SendRoutedMsg.
Dispatch: dNet/PacketDispatcher.h is a dispatch map from packet ID to (struct, handler
function); packets that fail to Deserialize are logged and dropped. The chat server's
switch and the world's HandlePacketChat switch are now maps. The handlers take the
structs; their logic is unchanged. World code sends to chat with ChatServerLink::Send
(dGame) instead of writing to Game::chatServer by hand. eChatChannel,
eChatMessageResponseCode and eAddIgnoreResponse moved to dCommon/dEnums so the structs
can use them.
Verified: tests/dGameTests/dNetTests/Legacy/ChatPacketsLegacy.h is a verbatim copy of
the old senders and readers; ChatPacketsTests (25 tests) sends a grid of inputs through
both and requires identical bits, bytes and destination, checks the old readers read
what the structs write, round trips every struct, checks truncated packets are refused,
and has hand written golden packets for general chat, canned text, GM mute and a routed
team game message. Breaking one field width (UpdateFriendNotify) and the TeamAddPlayer
zone flag made the tests fail. No wire bytes changed.

The login response's stamps were a fixed list: START and CLIENT_OS at the
start, an ERROR or two, and IM_LOGIN_START / WORLD_COMMUNICATION_FINISH
appended to every response whatever happened. Now a Stamps list (new
dNet/Stamps.{h,cpp}: eStamps, Stamp and Stamps with Serialize /
Deserialize in the login response's layout, so server messages can carry
it too) is created when the login request arrives, and each step adds its
own stamp, with the time, where it happens: the request read (value: the
client's OS), the account lookup (found or not), the password check,
failed checks, the closed server and play key checks, database writes,
asking master for a world, master's answer, handing the session key to
master, and sending the player on. The response serializes whatever was
stamped; the auth server logs the list like the client does.
What the client does with stamps (1.10.64): PacketHandler_MSG_CLIENT_
LOGIN_RESPONSE @ 00b32f90 reads them (LoginResponse::ReadStamps @ 005ed3c0,
count = (size - 4) / 16) and only logs each with its name from
StampLookup @ 017e6e88 (the 39 eStamps names) and its time relative to the
first and previous stamp. Documented in Stamps.h.
Behaviour change: on success, master gets the session key just before the
client gets the response instead of just after, so the handoff can be
stamped (and master knows the key before the client can reach a world).
The client-facing layout is unchanged; tests pin the stamp bytes, check
the steps of a failed login in order, and round trip the list.

Adds CommonPackets (ServiceType::COMMON): ClientVersionConfirm (the
client's handshake, with the handler that logs it and answers),
ServerVersionConfirm, DisconnectNotify and GeneralNotify (layout from the
1.10.64 client's PacketHandler_MSG_SERVER_GENERAL_NOTIFY; DLU does not send
it yet). AuthPackets::LoginRequest reads the login and keeps the old login
logic in its Handle; ClientPackets::LoginResponse (with the Stamp list)
replaces the hand written response, and AuthPackets::SendLoginResponse
fills it from the settings as before. dServer::Disconnect writes a
DisconnectNotify. AuthServer's if-chain and WorldServer's COMMON case
become CommonPackets::Handle / AuthPackets::Handle, dispatch maps that
read the struct, drop and log it if it does not deserialize, then Handle.
HandleHandshake and SendHandshake are gone.
No wire change. Verified against a frozen verbatim copy of the old
functions (tests/dGameTests/dNetTests/Legacy): the old handshake and login
handlers and the new dispatchers are fed the same packets and must send
identical bytes to the same address (same RNG seed for the session key),
over grids of versions, service types, ports, response codes, error
messages, IPs and stamp lists; plus hand computed golden bytes, round
trips, truncation checks, and a deliberate field width mutation that made
the tests fail. The only behaviour difference: truncated handshake and
login packets are now dropped instead of handled with whatever was read.
