Reviewer's Guide

Applies safe Ruff auto-fix formatting to backend tests and scripts, primarily reordering/sorting imports, normalizing spacing and class layout, and performing a few minor syntactic simplifications in test code and one script function without altering logic.

File-Level Changes

Change	Details	Files
Normalize and sort imports across backend tests for consistency with Ruff rules	Reordered standard library, third-party, and local imports into Ruff-compliant groups Consolidated duplicate or reordered imports within the same file Swapped import aliases or ordering where necessary to satisfy style rules (e.g., AIMessage/HumanMessage ordering) Ensured pytest and unittest.mock imports follow consistent ordering	backend/tests/test_supervisor.py backend/tests/test_utils.py backend/tests/test_graph_mock.py backend/tests/agent/test_supervisor_llm.py backend/tests/test_search_robustness.py backend/tests/test_validation_coverage.py backend/tests/test_search_router.py backend/tests/test_validation.py backend/tests/agent/test_middleware_security.py backend/tests/test_memory_tools.py backend/tests/test_mcp_tools.py backend/tests/agent/test_rate_limiter.py backend/tests/test_input_validation.py backend/tests/test_ipv6_rate_limit.py backend/tests/test_proxy_security.py backend/tests/test_rag_nodes_mock.py backend/tests/test_mcp_config.py backend/tests/test_state_types.py backend/tests/agent/test_checklist_verifier.py
Apply minor style and readability fixes in tests (spacing, blank lines, class separation)	Inserted or normalized blank lines between imports, classes, and functions to comply with Ruff formatting Adjusted multi-import lines into parenthesized or multi-line imports for readability and lint compliance Ensured fixtures, helper functions, and classes are visually separated and ordered consistently	backend/tests/test_utils.py backend/tests/test_state_types.py backend/tests/agent/test_checklist_verifier.py backend/tests/test_ipv6_rate_limit.py backend/tests/test_proxy_security.py backend/tests/test_rag_nodes_mock.py backend/tests/test_input_validation.py
Refine minor logic-safe expressions in scripts for clarity and lint compliance	Replaced explicit key-in-dict check plus truthiness with dict.get call in report generation script Used explicit string formatting with !s conversion instead of str(e) inside f-strings to satisfy style rules Standardized print string interpolation style in dev helper script	scripts/generate_sample_reports.py scripts/dev.py
Run Ruff auto-fix on additional backend test files without semantic changes	Applied import sorting, whitespace normalization, and other auto-formatting to remaining test modules Ensured no business logic or assertions were modified, only formatting and style	backend/tests/agent/test_orchestration.py backend/tests/agent/test_rag.py backend/tests/agent/test_rate_limiter_proxy.py backend/tests/conftest.py backend/tests/evaluators.py backend/tests/test_configuration.py backend/tests/test_gemma_compatibility.py backend/tests/test_kaggle_integration.py backend/tests/test_mcp.py backend/tests/test_nodes.py backend/tests/test_persistence.py backend/tests/test_planning.py backend/tests/test_registry.py backend/tests/test_research_tools.py backend/tests/test_state.py backend/tests/test_utils_hypothesis.py backend/tests/test_validate_web_results.py
