Feature: Stream Router remaining uncovered lines
  As a developer
  I want Behave scenarios that target remaining stream_router gaps
  So that additional uncovered branches are exercised

  Background:
    Given the CleverAgents reactive system is available

  Scenario: Converting dict route config uses defaults
    When I convert a dict route config with only a name
    Then the stream config should use default values

  Scenario: Converting object route config uses defaults for missing attrs
    When I convert a minimal object route config
    Then the stream config should use default values

  Scenario: Transform operator with type parameter applies replace
    When I apply a transform operator with type replace
    Then the transform operator should update the field

  Scenario: Switch operator emits original message with no matches or defaults
    When I run a switch operator with no matches and no defaults
    Then the switch operator should emit the original message

  Scenario: Unsupported condition returns false
    When I evaluate an unsupported condition
    Then the unsupported condition result should be false

  Scenario: Agent mapper falls back when no processing methods exist
    When I map a message with an agent lacking processors
    Then the mapper should return the original content with metadata
