RPC Factory

Create an RPC utility tree from an RPC group and a ready client.

`createRpcQueryUtils(group, options)`

Returns an eager, frozen RpcQueryUtils tree for the group’s unary and streaming RPCs.

Options

Option	Meaning
`client`	Ready flat RPC client. The caller owns its `Scope` and lifecycle.
`keyPrefix`	Non-empty, JSON-safe tuple that namespaces every generated key.
`runPromiseExit`	Runner used for RPC Effects. Required when client-side services remain; otherwise defaults to `Effect.runPromiseExit`.
`keyEncoders`	Synchronous encoders keyed by literal RPC tags. Required for payloads that need encoding services or contain redacted values.

const rpcQuery = createRpcQueryUtils(rpcGroup, {
  client,
  keyPrefix: ['web', 'v1'] as const,
  runPromiseExit,
})

The factory throws EffectRpcQueryConfigError for an invalid prefix, RPC path collision, reserved path segment, or invalid encoder map. It performs no network request.

The public RPC consumer checks factory inference and runner requirements.
