The design doc's `send_request = call` alias only makes the concrete class
satisfy RequestSender, not the abstract Dispatcher Protocol — so any consumer
typed against `Dispatcher[TT]` (Connection, ServerRunner) couldn't pass it to
something expecting a RequestSender without a cast or hand-written bridge.
RequestSender was also half a contract: every implementor (Dispatcher,
DispatchContext, Connection, Context) has `notify` too, and PeerMixin needs
both for its typed sugar (elicit/sample are requests, log is a notification).
Outbound(Protocol) declares both methods; Dispatcher and DispatchContext extend
it. PeerMixin will wrap an Outbound. One verb everywhere, no aliases, no extra
Protocols.
- Dispatcher.call -> send_request
- OnCall -> OnRequest, on_call -> on_request
- RequestSender -> Outbound (now also declares notify)
- Dispatcher(Outbound, Protocol[TT]), DispatchContext(Outbound, Protocol[TT])
