Feature: Reactive routing and route bridge port
  Validate minimal reactive stream routing and route bridge behavior in actor-first mode.

  Scenario: Create a cold stream and send a message
    Given a reactive stream router
    When I create a cold stream named "alpha"
    And I send message "hello" to stream "alpha"
    Then the stream "alpha" should exist

  Scenario: Initialize route bridge with dummy registry
    Given a reactive stream router
    And a dummy actor registry
    When I create a route bridge
    Then the route bridge should include agent "dummy"

  Scenario: Convert stream route to graph config via bridge
    Given a reactive stream router
    And a dummy actor registry
    And a stream route config named "s1" with a map agent operator
    When I create a route bridge
    And I convert the stream route to a graph config
    Then the graph config should contain nodes
