Ninth batch of the 250-line sweep. Every Python file in the repo is now under
cap (over-cap count 25 -> 18; the 18 remaining are all Dart).
_foodbank.py 365 -> 210 (+ _foodbank_search, _foodbank_rebuild)
test_averages.py 351 -> 222 (+ test_averages_report.py)
_estimator.py 325 -> 137 (+ _estimator_off.py)
_budget.py 323 -> 227 (+ _budget_biometrics, _budget_derived)
test_foodbank.py 311 -> 117 (+ test_foodbank_rebuild.py)
_averages.py 298 -> 174 (+ _averages_periods, _averages_report)
test_budget_history.py 288 -> 162 (+ test_budget_history_io.py)
The split boundaries are constrained by which module owns each conftest-patched
state path, not by line count. BUDGET_FILE stays in _budget, FOOD_BANK_FILE in
_foodbank: the derived/search/rebuild halves reach the file only through their
parent's private helpers. Two of the new modules had copied FOOD_BANK_FILE into
their headers as an incidental import, which is exactly the leak the guard is
for -- both cleaned.
test_state_redirect.py now covers all five redirected paths (FOOD_LOG_FILE,
BUDGET_FILE, BUDGET_HISTORY_FILE, FOOD_BANK_FILE, MANUAL_BANK_FILE) rather
than just the food log, in both directions: only the owning module may name
each constant, and each redirect demonstrably moves a real write off the live
path.
Two rewires fail-closed rather than silently: `_budget.budget_weight` and
`_estimator.requests` were module-attribute references no import rewrite
touches, and both raised AttributeError immediately. The latter appeared only
after ruff removed the now-unused `requests` import from _estimator -- the
import was load-bearing solely as a patch target.
Verified: 707 Python tests / 100% branch coverage, 5 layout-fits tests under
xvfb, check_patch_targets 0, pre-commit clean, ~/.local/share/diet_guard
byte-identical.
