Frequency-Domain Analysis Using Tree-sitter
TF-IDF (Term Frequency-Inverse Document Frequency) identifies changes that are rare across the entire refactoring but significant in specific locations.
bool_type_change - Boolean literal changed to variable (or vice versa) - HIGH RISK!param_added - New parameters added to constructorarg_type_change - Argument type changed at positionvalue_change - Argument value changed at positionFrequency analysis shows how often each change pattern occurs across the refactoring.
|z| > 2.0 - Statistical outlier (marked as ANOMALY) - investigate!|z| < 2.0 - Normal variationUnified diff shows before/after view of constructor calls, similar to git diff.
Pattern analysis groups similar changes and identifies statistical outliers.
