2V1-d: offline login -> select -> loading against a fake 40250 server
port.login_flow drives the real 40250 root scripts through the ported CPythonNetworkStream and CAccountConnector against a loopback auth + game server built from net/classic (wire layouts, sequence table, cipher) that answers like the 40250 desc.cpp/input*.cpp: handshake, key agreement, LOGIN3/AUTH_SUCCESS, LOGIN2, the character list, DirectEnter reconnect, CHARACTER_SELECT, the loading packets and CLIENT_VERSION, with every sequence byte checked. - NetStream::ActivateCipher decrypts ciphertext already buffered behind KEY_AGREEMENT_COMPLETED (PORT) - CPythonApplication is final (PORT): no application object exists on the platform yet, so its virtual overrides must be called directly - app.GetTime (GetGlobalTime) and camera/center-position stubs - SendClientVersionPacket verbatim in the PhaseGame stand-in Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
