Add 13 BDD scenarios covering previously uncovered code paths: - SAFE_BUILTINS validation (sandbox.py: 0% → 100%) - ConfigurationError re-raise path (config.py: 99.3% → 100%) - CLI hello/main functions (cli.py: 72.7% → 90.9%) - GraphState message truncation (state.py: 98.7% → 100%) - ProgressBarManager update/context rendering (progress.py: 0% → 87.7%) - MessageRouter regex/exact/contains routing (message_router.py: 0% → 59.4%) - RoutingAdapter parse_routing_command (routing_adapter.py) - DynamicRouterNode pattern-based routing (dynamic_router.py) - EnhancedTemplateRegistry unknown template type (enhanced_registry.py: 99.2%) - CompositeAgent null-graph error path (composite.py: 97.8% → 98.6%) Cover routing_adapter.py (17% → 100%): all GOTO/ROUTE patterns, create_routing_node, create_conditional_router, dynamic config conversion. Cover dynamic_router.py (21% → 87%): execute with empty/dict/string messages, extract_message with colon parsing, config creation, graph extension with edge generation. Cover message_router.py (59% → 78%): regex, exact, contains, prefix, suffix match types, invalid regex handling, non-string message, set_state. Exercise Node._prepare_conversation_history with invalid configs, _runtime error paths, _execute_message_router with rules, _execute_agent with current_message and metadata propagation, _execute_function with dynamic_router, and _execute_conditional with content_contains/content_not_contains/content_starts_with and custom condition types. Improves nodes.py from 71.3% to 72.5%. Exercise PureGraphConfig, PureLangGraph init with dict/config, RxPyLangGraphBridge registration/connection/lookup, ReactiveStreamRouter operator creation and condition functions, ReactiveConfigParser config/route/graph parsing, ToolAgent tool execution with JSON, space-separated, single, file_read, progress_bar invocations, and ReactiveCleverAgentsApp init/dispose/visualization.

Feature: Bridge Event Loop Management, Task Cleanup, and Metadata Handling
|
|
As a developer
|
|
I want the bridge to handle closed event loops, cancelled tasks, metadata in executors, and cleanup with async/sync paths
|
|
So that the bridge recovers from event loop failures, cleans up tasks, and propagates metadata correctly
|
|
|
|
Background:
|
|
Given a fresh bridge gaps test context (brg)
|
|
|
|
Scenario: Metadata passed to graph state in executor
|
|
Given a bridge with a mock graph named "meta_graph" (brg)

|
|
Given a bridge with a mock graph named "cl_loop_graph" (brg)

|
|
|
|

|
|
Given a bridge with a mock graph named "err_loop_graph" (brg)
|
|

|
|
Then the exception should be set on the future (brg)
|
|
|
|
Scenario: Task result handler handles CancelledError

|
Given a bridge gaps test context (brg)

|
|
Scenario: Task result handler handles generic Exception

|
|
Given a bridge has mock graph named "node_graph" with node named "worker_node" (brg)

|
|
Given a bridge with a stream "stm_graph" and graph "stm_graph" (brg)
|
|
When I connect stream to graph with no running loop (brg)
|
|
Then a new event loop should be created for the stream-to-graph connection (brg)
|
|
Given a bridge gaps test context (brg)
|
|

|
|
