// MISSION BRIEF

Your Mission

Every MCP session opens with a strict handshake: the client sends initialize, the server answers with its capabilities, then the client sends notifications/initialized. Version and capability negotiation happen here. Get the order or the negotiation wrong and features silently vanish.

Scoring: equal weight per question.
