📝 Walkthrough

Walkthrough

Comprehensive PR adding AI-assisted issue triage with confidence scoring to the code analyzer pipeline, improving type safety across modules, enhancing CI/CD workflows, and normalizing documentation formatting. Includes new AISuggestionFixer fallback mechanism and batch evaluation interface for LLM orchestration.

Changes

Cohort / File(s)	Summary
Configuration & CI/CD .flake8, .github/workflows/auto-label.yml	Added Flake8 linting config with max line length 100, ignoring E203/W503. Updated GitHub Actions to use pull_request_target trigger, added explicit GITHUB_TOKEN input, and promoted contents read permission.
Debug & Utility debug_syntax.py	New script iterating over parser.py and indexer.py to detect non-ASCII bytes, validate syntax with ast.parse, and check for PY_LANGUAGE byte sequences with exception handling.
Core AI Triage Feature refactron/analyzers/code_smell_analyzer.py, refactron/autofix/engine.py, refactron/autofix/fixers.py, refactron/llm/orchestrator.py	Introduced AI-assisted triage: CodeSmellAnalyzer now accepts optional orchestrator; AISuggestionFixer added for AI-generated code suggestions; AutoFixEngine extended to use AI suggestions as fallback; LLMOrchestrator now provides batch evaluation interface returning confidence scores for filtering issues (threshold 0.3) and triggering suggestion generation (threshold 0.8).
Configuration & Core Modules refactron/core/config.py, refactron/core/config_loader.py, refactron/core/refactron.py, refactron/core/repositories.py, refactron/core/workspace.py, refactron/core/memory_profiler.py	Added enable_ai_triage boolean flag to RefactronConfig with YAML serialization. Moved analyzer imports inside _initialize_analyzers for lazy loading. Minor comment formatting and error message restructuring. Added type: ignore annotations for external imports.
LLM Modules refactron/llm/backend_client.py, refactron/llm/client.py, refactron/llm/models.py, refactron/llm/safety.py	Enhanced type safety: explicit return type annotations, str casting for content, boolean normalization for health checks. Added type hints to internal helpers and type: ignore for SentenceTransformer imports.
CLI & Scripts refactron/cli.py, scripts/analyze_feedback_data.py	Added explicit return type annotations (-> None) to suggest and document CLI handlers, fixed interactive path return type to Path. Updated analyze_feedback with return type Optional[Dict] and removed dynamic path insertion.
RAG Modules refactron/rag/indexer.py, refactron/rag/parser.py, refactron/rag/retriever.py	Enhanced tree-sitter initialization with fallback logic for multiple API variants. Added explicit typing for Dict[str, int], Set[str] return types. Improved error message formatting. Made CHROMA availability explicit with None fallback on import failure.
Documentation docs/*, documentation/docs/*, docs/docs.json	Comprehensive formatting normalization: removed/added blank lines around Accordion and Step components, standardized spacing around code blocks. Fixed CLI reference table alignment and --version flag format. All changes are whitespace-only with no content alterations.
Test Suite tests/test_ai_autofix.py, tests/test_analyzers.py, tests/test_backend_client.py, tests/test_config_loader_edge_cases.py, tests/test_config_management.py, tests/test_llm_orchestrator.py, tests/test_patterns_integration.py, tests/test_rag_indexer.py	Added new integration tests for AI autofix workflow with mocked orchestrator, testing high/low confidence thresholds. Added ai_triage filtering test in analyzers. Cleaned up imports and simplified pattern isolation checks. Added type: ignore annotations to yaml imports.
