SHARED LOBBY RELEASE VALIDATION PUMPKO 1.6.0 / ANetARCADE 1.3.0 / Chat Hub 1.0 Native builds: Linux x64 and ARM64 static, Windows x86 and x64. Windows networking uses OS WinHTTP/TLS 1.2 and native HMAC-SHA256. All eight platform ZIPs contain three files: installer, README, FILE_ID.DIZ. Verified locally: - Six service tests: cross-game/BBS messages and counts, replay/ownership, terminal controls, duplicate events, cursors, rate limits, live credential reload, BBS disabling, session expiry, caller deduplication and signatures. - Two real OpenDoors games in PTYs exchanged messages through a trusted local HTTPS service and returned to their games. Profiles were saved. - ANetARCADE submits its handle with one LF Enter; PUMPKO input/profile regression smoke passed. ARM64 terminal smoke tests passed under QEMU. - Fresh Linux installers run without Python. Upgrade tests preserve config, unknown fields, chat credentials, scores and profiles. Disabled chat stays hidden. Malformed chat config remains unchanged. Chat settings use 0600. - Existing PUMPKO Hub/enrollment/native tests passed. Story/Daily cache permissions remain 0644, including unchanged cache repair. - PE architecture and OS-only DLL imports; all Windows embedded payload bytes matched staging. Linux payloads matched staging and are static. - Supplied OpenDoors and working PUMPKO score networking/sync/migration code remain unchanged (972 original files checked). Limits: Windows packages were cross-compiled and inspected; they still need a real Windows 7/BBS playtest. ARM used QEMU, not Raspberry Pi hardware. The public chat service has NOT been deployed; DNS, nginx TLS and systemd deployment are still required. No real Hub enrollment or production messages were sent. ANetARCADE's high scores remain local; this release adds shared chat only. Presence counts cover chat-enabled game callers, with a 45-second timeout. ASCII chat, 160-character messages, 16 wrapped display lines, 24-hour history.
