<out TMethod is non-empty-string, out TResult is Result, in TContext is AbstractContext>

Handles a single inbound JSON-RPC request and returns the typed result. TMethod binds the literal returned by static::getMethod() on the matching request class so the registry can store handlers heterogeneously. It does not narrow handle()'s parameter, which stays at the wide envelope type.
