`requires-python` and the CI pin already said 3.14, but ruff, mypy and pylint were still grading against 3.10 -- three tools judging an interpreter nothing runs any more, and ruff withholding the pyupgrade fixes that only become safe at the newer target. `pin_ci_python.py` rewrites exactly these three knobs. The fixes ruff then had to make are what the stale target was hiding: 18 files on `datetime.timezone.utc` instead of `datetime.UTC` (UP017), plus ruff's stable formatter applying PEP 758 -- `except (A, B):` becomes `except A, B:`. That second one makes the source 3.14-only at the syntax level, which is exactly what `requires-python = ">=3.14"` already promised; kuhy chose it deliberately over holding ruff a release back (2026-08-29). ruff, ruff-format, mypy --strict and pylint all clean at the new target.

"""Hand-curated food bank entries: foods added without ever eating them.
|
|
|
|
The main food bank (:mod:`diet_guard._foodbank`) is *derived* -- every record
|
|
is replayed from the synced food log, so both devices compute the same bank
|
|
from the same input and it needs no sync of its own. This module holds the
|
|
part that is **not** derivable: entries the user added by hand in the phone
|
|
app's food-bank screen, which never appear in any log.
|
|
|
|
Those were previously phone-only, which made them the last piece of
|
|
device-local state in the app. They now sync like everything else -- one
|
|
``crdt_sync`` record per normalized name, last-writer-wins by edit time -- so
|
|
a food added on the phone autocompletes in the PC gate and vice versa.
|
|
|
|
Kept in a separate file from the derived bank on purpose: the derived bank is
|
|
rewritten wholesale on every log write (:func:`diet_guard._foodbank.
|
|
rebuild_food_bank`), so storing curated entries there would lose them on the
|
|
next meal.
