Map data flows and debug end-to-end

Trace data flow through codebase end-to-end

Finding where a feature or bug lives by tracing the complete data flow with file:line accuracy

• · symptom, feature name, or data path

• · entry point file and function
• · transformation chain with line numbers
• · failure points identified
• · finding recommendations

• · grep
• · git log

• · codebase is searchable
• · entry point can be identified

• · entry point not found
• · flow crosses language boundaries unclear
• · data transform hard to trace

• · maps function-by-function
• · identifies data transformations
• · names ownership boundaries
