food_bank_screen.dart (712) carried a near-clone of the filter sheet batch 2
had just factored out of history: the same name-search field, the same slider
captions, and four more copies of the same min/max macro range block. Splitting
it in isolation would have baked that duplication in permanently, so the shared
widgets moved to a neutral `lib/widgets/filters/` first and both screens now
import them.
food_bank_screen.dart 712 -> 238
lib/widgets/food_bank/
fb_filter.dart 156 FbFilter, FbSortField, applyFbFilter
fb_filter_sheet.dart 244 the sheet itself
fb_add_entry_dialog.dart 103 the manual-entry dialog
lib/widgets/history/history_filter_fields.dart
-> lib/widgets/filters/filter_fields.dart
FilterRangeRow gained `showEndpointLabels`, defaulting to true. History showed
endpoint captions and a selected-range readout; the food-bank sheet never did,
and switching them on there would have been a UI change smuggled in under a
refactor. The food-bank call sites pass false, so both screens render exactly
what they rendered before.
FbSortField and HistorySortField stay separate on purpose -- they are not the
same enum (`name` vs `date`/`description`), so the sort dropdown is not shared.
The test file mirrors the source split, three files under test/screens/
food_bank/ plus fb_test_support.dart for the setUp/tearDown/settle prologue,
same shape as batch 2's history_test_support.dart.
Verified: 555 flutter tests (unchanged count -- no test lost, and food bank's
own RangeSlider/sort-toggle tests still pass against the shared widget),
flutter analyze clean over lib/ and test/, live ~/.local/share/diet_guard
byte-identical. Over-cap files: 40 -> 38.

history_screen.dart (1052) and history_screen_test.dart (1017) were a third of
the remaining over-cap work. Widget extraction only -- no route changes, since
routes are user-visible and repo_invariants_test.dart pins the navigation
surface.
history_screen.dart 1052 -> 211
lib/widgets/history/
history_filter.dart 102 filter criteria + sort enum (pure data)
history_grouping.dart 206 HistoryItem tree, apply/group/format
history_list.dart 194 GroupedList, DayHeaderTile, EntryTile
history_filter_sheet.dart 242 the sheet itself
history_filter_fields.dart 168 search field, slider labels, range row
history_filter_sort.dart 140 source chips + sort controls
Names that now cross a file boundary became public (HistoryItem, DayHeader,
EntryRow, buildGroupedItems, formatDay, dateRangeLabel, the tile widgets), each
with the doc comment public_member_api_docs requires -- 49 of them, written
rather than suppressed.
The four macro range sliders (kcal/protein/carbs/fat) were four near-identical
30-line blocks differing only in label, key, unit and which HistoryFilter pair
they read/write. They are now one FilterRangeRow taking min/max plus an
onChanged, which is most of how the sheet got under the cap.
The test file mirrors the source split one-for-one, six files under
test/screens/history/. Its setUp/tearDown and the settle() helper (needed by
every part, because HistoryScreen loads via an untracked initState future) moved
to history_test_support.dart rather than being copy-pasted six times.
Verified: 555 flutter tests (same count as before -- no test lost in the split),
flutter analyze clean over all of lib/ and test/, 701 python tests at 100%
branch coverage, `python -m diet_guard sync` -> 402 entries/exit 0, live
~/.local/share/diet_guard byte-identical. Over-cap files: 42 -> 40.
