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.

The calendar already said which individual days went over budget, but not
whether the week as a whole did. A run of small overages reads as four
harmless yellow squares; averaged, it is the thing that actually moves the
needle.
Three rules are load-bearing, and are documented in CLAUDE.md because getting
any of them wrong silently changes what "under budget" means:
- The denominator is logged days, not elapsed days. An unlogged day is not a
zero-kcal day, and averaging gaps in as zeros would make a badly-tracked
week look like the best week of the year.
- The yardstick is the mean of the per-day budgets over those same days,
resolved through BudgetSchedule -- never today's budget, which would
retroactively reclassify past weeks on every budget edit.
- Today is excluded. A half-logged today drags the mean far enough to flip
the band, so every period ends at yesterday.
Band boundaries reuse the calendar's own OVER_BUDGET_YELLOW_CEILING by
import rather than by copy, so a period and its days can never disagree
about what "over" means; that constant loses its underscore to say so.
The MCP get_averages tool returns the average and the band but drops the
average budget, keeping the module's existing invariant that the budget
number never leaves this machine. The CLI, the gate and the phone all show
both, since it is hidden from the network, not from the user.
