docs/refactor/BaoCao_TeamDuy_R01_R03_R04.md records what was delivered against
each of the 16 tasks, the measured evidence (243 tests, 218 of them in 1.22s;
check_imports PASS; no production file over 400 LOC), the three real defects
found while working - the routing_application() deadlock, the swallowed
"notice" event, and the suite silently testing a different checkout - plus the
six open decisions and, explicitly, what was NOT tested (no manual app launch,
no real provider traffic, tools/check_*.py not run).
Refactoring_Checklist.md now links to it from the progress block.
