Enum RpcResponse 

pub enum RpcResponse {
    Success {
        jsonrpc: JsonRpcVersion,
        id: RpcId,
        result: Value,
    },
    Failure {
        jsonrpc: JsonRpcVersion,
        id: RpcId,
        error: Value,
    },
}

A JSON-RPC 2.0 response (worker -> host): result XOR error, never both, never neither (JSON-RPC 2.0 §5). Modeled as an untagged enum of two complete structs so the illegal states are unrepresentable. Deliberately NOT #[serde(flatten)] over an untagged inner enum — that serde combination double-buffers (flatten → map, untagged → Content) and is a known deserialize failure mode (fails outright or degrades integers to floats).

The XOR is enforced at the deserialize boundary by a hand-written Deserialize (below), not merely asserted by the type shape: a plain untagged derive would match Success first and silently DROP a present error when both keys appear, letting a failed worker call read back as a bogus success. Serialize stays derived (untagged → each variant emits just its fields).
