… the disconnect flow Review follow-up on jamulussoftware#3794: - "On new connection" for the Client is now defined: the first audio packet from the Server (CChannel::PutAudioData returns PS_NEW_CONNECTION). The Server's REQ_* messages have been answered by then; the four messages the Client sends are unrequested, and the list now includes REQ_CHANNEL_LEVEL_LIST, which CClient::OnNewConnection sends and the previous text omitted. - The disconnect sentence claimed the Client sends CLM_DISCONNECTION repeatedly until the Server stops streaming. On the wire the Client stops its audio, answers packets arriving during its ~100 ms wait, sends one final CLM_DISCONNECTION and is done; the Server stops streaming on receipt, or times out 30 s after the Client's last packet. - The legacy-ID sentence said ID 28 is no longer sent; the Client sends it once per connection. - Two wording suggestions from review applied ("server list"). Measured 2026-09-05 with a pristine main build (72e856a) of client and server, tcpdump on loopback, three scenarios (GUI disconnect against a real server, GUI disconnect against a fake server that keeps streaming, SIGKILLed client): rig-3794/wire in the upstream workspace.

We may want to drop this backwards compatibility one day.
…pell out both Directory roles Two review points from @ann0see: - The ACKN sentence spelled out that an acknowledgement is not itself acknowledged, which is general protocol knowledge. Replaced with the part that is specific to this code: CreateAndImmSendAcknMess() emits the message directly rather than putting it on the send queue, so the retransmit machinery described above it does not apply. - "both roles" was too terse. Named the class and the flag: CServerListManager's bIsDirectory selects between keeping the registered Server list and registering with a Directory, and Register(), Unregister(), Append(), Remove() and RetrieveAll() each branch on it.

… and the hole-punch exception Two findings from CodeRabbit, both checked against jamulussoftware/jamulus main at 267bf6b: - The new-connection sequence went straight from CLIENT_ID (32) to CONN_CLIENTS_LIST (24). CServer::OnNewConnection sends RAWAUDIO_SUPPORTED (36) between them (server.cpp:403, :408, :414), guarded by !bDisableRaw, which only --noraw sets (main.cpp:519-522). The message table already carried row 36; the sequence did not. - The NAT hole-punching bullet said the Directory sends CLM_SEND_EMPTY_MESSAGE (1008) to every registered Server. CServerListManager::RetrieveAll sends it only where NetworkUtil::IsPrivateNetworkIP rejects the registered address (serverlist.cpp:722, :734, :740), and its loop starts at list index 1 (:717), so the Directory's own entry never gets one either.
