Module frame 

The frames a WebTransport subscription session carries (docs/design/subscriptions-websocket.md §6.4, §6a.2).

Field names follow what already ships rather than the older §2.3 sketch: a request is the batch binding’s RpcRequest shape (id, op, input), and items/errors use the SSE binding’s next/err (cratestack-axum/src/rpc/sse.rs). A frame’s kind is whichever of init/op/ready/next/end/err is present — there is no separate type tag, so new kinds are additive.
