Adopt the four markdown namespaces and gate them 
Renames this repo's markdown onto README.md / CLAUDE*.md / DOCS*.md /
TODO*.md so a future session can tell a live task from a finished
record without reading the file to find out.

TODO files carry the literal "REMOVE ME AFTER FINISH" and are deleted
when the work lands. Enforced by the md-naming pre-commit hook and CI
workflow, both delegating to the shared gate in kuhyx/utils so this
repo's idea of a valid name cannot drift from every other repo's.

Includes the patch bump this repo's bump-patch-version hook applies to
app/pubspec.yaml on every commit.

Kuchnia Wikinga on the phone

The Dart half of the catering import. Read kuchnia-wikinga.md first — the API map, the traps and the delivered-is-not-eaten rule all live there and are not repeated here.

app/ carries a Dart mirror of the whole walk, so the feature works with the PC switched off. The files map one-to-one:

Python Dart
_kuchnia_client.py services/kuchnia_client.dart
_kuchnia_orders.py services/kuchnia_orders.dart
_kuchnia_parse.py services/kuchnia_parse.dart
_kuchnia_spread.py services/kuchnia_spread.dart
_kuchnia_import.py services/kuchnia_import.dart
_gatelock_kuchnia.py screens/log_meal_kuchnia_mixin.dart + services/kuchnia_queue.dart

Android only. The panel sends no CORS headers, so a browser cannot call it; refreshDelivery checks kIsWeb first and returns a reason. The settings fields still show on web — the desktop app is where a password is most likely to be typed, and the credential syncs from there to the phone.

package:http has no cookie jar, so the SESSION cookie is read off the login response and replayed by hand. Response.headers folds duplicate set-cookie values into one comma-joined string, so the parser splits on both , and ;.

What the parity gate covers, and what it does not

tests/fixtures/kuchnia_day.json is one payload with one expected result, read by both diet_guard/tests/test_kuchnia_parity.py and app/test/kuchnia_parity_test.dart. It pins the dish list, the dropped dishes, the slot assignment, the bank keys and the encoded records. A second fixture, kuchnia_credential.json, does the same for the credential adapter.

Three traps it exists for, each of which passed review once:

  • _ENERGY_TOLERANCE is 0.35, not the "~1%" quoted above for the captured day. Porting 0.01 would drop dishes the PC keeps, and then each device re-adds what the other dropped.
  • jsonEncode(435) emits 435 where Python emits 435.0. Every Dart macro is declared double, and the fixture compares canonicalised encodings, not just values — 435 == 435.0 is true, so a value-only test misses this.
  • Dart's List.sort is unstable; Python's sorted is stable. The Dart comparator carries the payload index as a final tiebreak, and the fixture contains two dishes sharing both a priority and a name.

The gate proves the two implementations agree on a fixed payload. It does not prove they agree against the live panel on a given day; that is a separate, on-device observation.
