SessionConfig

The open configuration extension object shared by session/start and session/resume (ADR 32760 D1).

Unknown keys are ignored on the wire, never rejected: the live decoder is ’s tolerant path, and keeps every exported bundle free of additionalProperties: false. The Rust typed model’s deny_unknown_fields is internal and never exported — the closedness export applies nowhere, and the x-msp-closed opt-in mechanism stays inert. Recognized mcpServers values are typed and validated before they leave the wire boundary.
