Leaf-set extraction only, so every new import is one-way and no cycle is
possible:
_stats.py 523 -> 233 + _stats_types (the shared _GameTimes dataclass,
imported by parent and helpers alike),
_stats_gathering, _stats_display
scanning.py 521 -> 248 + _scanning_candidates, _scanning_assign,
_scanning_tampering
_GameTimes and the four moved scanning helpers are re-exported from their
original modules via __all__ (mypy --no-implicit-reexport needs them listed),
so callers and tests keep their existing import paths.
Test patch targets were retargeted per file from the pytest failure list —
the target is the module whose source now contains the function under test.
Note TestPrintScenario and TestDoCheck did NOT move, so they keep the
original target while the rest of their files change.
1344 tests, 100.00% coverage. ./run.sh status and ./run.sh stats verified
against the live install; service at 0 restarts.
