 ### Migration metric
 
-Autoloop tracks `python_lines_migrated_pct = (migrated_python_lines / original_python_lines) * 100`. The best recorded value is **21.08%** (iteration 35, 15,116 of 71,696 lines). `go build ./...` and `go test ./...` pass on all accepted iterations. Module-specific Python-vs-Go timing data is not yet present in `benchmarks/migration-status.json`.

 ## Operating notes
 
 - Prefer leaf modules first; fewer internal APM dependencies and lower integration risk.
 - Keep Go implementations stdlib-only when sandbox networking blocks external module fetches.
 - Record every accepted iteration in `benchmarks/migration-status.json` so this page can report complete module data.
