- _file_to_package: infer package from file path (kotlin/java/python/src)
- _top_packages: most common packages per cluster
- Packages included in meta dict and JSON output
- New tests: test_file_to_package, test_top_packages, test_extract_imports,
test_extract_imports_empty, test_extract_imports_no_imports,
test_extract_arg_info_python, test_summarize_arg_info
- _extract_imports scans source files for language-agnostic import patterns
- analyze_clusters tracks file paths through frequency_filter via identity
- Each cluster output includes its unique imports and file paths
- --json flag outputs structured JSON for LLM prompt injection
- Flat mode (--cluster false) also extracts imports
- _extract_call_tokens filters to call-like captures only
- cluster_methods groups sequences by shared 3-gram call patterns
- analyze_clusters runs per-cluster CRX/iDRegEx/kORE inference
- Lists 17 convention clusters for RAGSAK test code
- iDRegEx and kOREInference now produce ordered grammars per cluster
- (other) cluster captures diverse conventions as CRX vocabulary
- min-cluster-size (default 3) and ngram-size (default 3) CLI flags
- _find_method_bodies uses tree-sitter's universal body field (9/10 grammars)
- Kotlin fallback: scan children for body-like types
- preprocess_by_method groups highlight captures by enclosing method body
- Returns per-method sequences for k-ORE ordering analysis
- analyze.py infer() now uses preprocess_by_method
- Document findings in ANALYSIS.md
- 97 tests pass
