The phone is getting its own Kuchnia Wikinga importer so the feature works
with the PC switched off. That turns a risk `_kuchnia_spread.py` called
"theoretical" into a live one: two implementations must now agree exactly on
which dishes are dropped, which slot each lands on, and the JSON a banked
record encodes to. Disagreement means each device re-adds what the other
dropped, and since `add_manual_entry` restamps `t` unconditionally, the whole
curated bank republishes to every peer on every refresh. A slot mismatch is
worse -- a checkpoint one device offers and the other does not can never be
satisfied.
So the port lands with its gate rather than after it. One shared fixture,
`tests/fixtures/kuchnia_day.json`, is asserted by both `pytest` and
`flutter test`: same input, same expected dishes, drops, slots, bank keys and
records. Two suites written independently from the same prose is not a gate.
The fixture is five real dishes (a scrubbed 2026-08-22 capture) plus synthetic
meals that each pin one drop or fallback path -- a per-100 g mix-up, an absurd
portion, a stringly-typed number, a non-dict entry, a missing `nutrition`, a
missing `mealPriority`, and a twin-dish pair. Without those, "the same meals
are dropped" is a vacuous assertion against an all-happy-path capture. Both
halves were mutation-checked: flipping an expected slot, drop count or record
value fails each suite, and flipping `435.0` to `435` fails the byte-identity
test while the value comparison still passes, which is why both exist.
Three traps the port had to survive, each caught before it shipped:
- `_ENERGY_TOLERANCE` is **0.35**. The prose said "~1%", which describes how
closely the captured day agreed, not the threshold; porting 0.01 would drop
dishes the PC keeps. That paragraph now says so.
- `jsonEncode(435)` emits `435` where Python emits `435.0`, so every Dart
macro is forced to `double` and a canonical-encoding test pins it.
- Dart's `List.sort` is unstable where Python's `sorted` is stable, so the
Dart comparator carries the payload index as a final tiebreak.
The real dishes live in their own file rather than as a literal in the
generator: transcribing them by hand corrupted three of the five, and the
error was invisible until the generated fixture was diffed against the
capture.
