Top-level GameMessage (UIQueue), not a GameEvent. Server sends when an object leaves the client's inventory view (sold / dropped / destroyed). Layout: opcode(4) + guid(4) = 8 bytes — the smallest inventory wire. 3 tests: happy path, wrong opcode, truncated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
