* test(event_bus): add tests for new worker monitoring events
Add tests for newly added emit methods:
- emit_worker_escalation_ticket (judge → queen escalation)
- emit_queen_intervention_requested (queen → operator escalation)
- emit_llm_turn_complete (LLM turn metadata)
- emit_node_action_plan (node planning)
Update test_key_event_types_exist to include:
- WORKER_ESCALATION_TICKET, QUEEN_INTERVENTION_REQUESTED
- LLM_TURN_COMPLETE, NODE_ACTION_PLAN
- WORKER_LOADED, CREDENTIALS_REQUIRED
Total: 45 tests (up from 41)
* test(event_bus): add tests for run_id, subagent_report, and new event types
- Add tests for run_id field in AgentEvent.to_dict()
- Add test for emit_subagent_report convenience method
- Update test_key_event_types_exist with new event types
- Total: 48 tests
* fix(test): remove tests for deleted EventBus methods and fix enum names
Remove test_emit_worker_escalation_ticket and
test_emit_queen_intervention_requested (methods were removed in recent
refactors). Fix WORKER_LOADED -> WORKER_GRAPH_LOADED in enum assertions.
* style: add future annotations import and fix empty assertion in test_emit_node_action_plan
* feat(tools): add Weights & Biases experiment tracking and model monitoring integration
* style: fix ruff formatting in wandb_tool.py
* feat(tools): add Weights & Biases ML experiment tracking integration
* fix(tools): address CodeRabbit review comments on wandb_tool
* fix(tools): rewrite wandb_tool to use official Python SDK instead of undocumented REST endpoints
* fix(tools): address Hundao review — remove .coverage, switch to GraphQL/httpx, fix wandb_host, add README
* fix(tools): wire filters to GraphQL, validate empty metric_keys, fix line lengths
* fix(tools): check credentials before input validation in wandb_get_run_metrics
Move _get_creds() call before run_id/metric_keys checks so the
framework credential test receives the expected {error, help} response
instead of a bare input-validation error.
* fix(test): update queen memory test mocks to match litellm ModelResponse format
PR #6976 refactored reflection_agent to extract tool calls from litellm
ModelResponse objects (choices[0].message.tool_calls) instead of plain
dicts. The test mocks were not updated, causing tool calls to silently
fail and two tests to break.
Fixes#6990
* style: ruff format
