Feature: Route Missing Coverage Lines As a developer I want to test specific missing coverage lines in route.py So that I achieve 90%+ coverage Background: Given the route system is available Scenario: Direct from_stream_config method call with all properties Given I have a StreamConfig with all optional properties set When I call RouteConfig.from_stream_config directly Then line 170 should be executed And all stream properties should be copied correctly Scenario: Direct from_graph_config method call with complex nodes Given I have a GraphConfig with nodes having all optional properties When I call RouteConfig.from_graph_config directly Then lines 187-216 should be executed And nodes with tools should be converted And nodes with retry_policy should be converted And nodes with timeout should be converted And edges with conditions should be converted Scenario: Stream complexity analysis with hot stream type Given I have a hot stream RouteConfig When I analyze stream complexity Then line 273-274 should be executed for hot stream detection Scenario: Graph complexity analysis with conditional edges Given I have a graph with multiple conditional edges When I analyze graph complexity Then lines 303-304 should be executed for conditional edge counting Scenario: Stream recommendation for complex score Given I have a stream with complexity score of 8 When I get stream recommendation Then line 328 should be executed Scenario: Graph recommendation for advanced score Given I have a graph with complexity score of 18 When I get graph recommendation Then line 340 should be executed Scenario: Route type suggestion with all requirement combinations Given I have requirements with needs_state and needs_conditionals true When I get route type suggestion Then line 351 should be executed And it should return GRAPH Scenario: Route type suggestion with conditionals but not continuous Given I have requirements with conditionals true but continuous false When I get route type suggestion Then line 353 should be executed And it should return GRAPH Scenario: Route type suggestion with stateless and continuous Given I have requirements with stateless and continuous true When I get route type suggestion Then line 355 should be executed And it should return STREAM Scenario: Route type suggestion default case Given I have simple requirements When I get route type suggestion Then line 358 should be executed as default And it should return STREAM
