The Dart half of the credential sync: a `KuchniaCredentialService` that owns the value locally, a `sync_merge_kuchnia.dart` adapter mirroring the Python one, and a `_syncKuchniaCredential` tick alongside the banks and budget. The phone can now receive the panel password, which is the prerequisite for it fetching anything itself. One source of truth, per the answered question: the value lives in the synced document store and nowhere else. Deliberately *not* mirrored into `flutter_secure_storage` -- two homes for one value is how a stale password survives a change made on the other device, and the credential has to be readable synchronously at merge time anyway. Gated by a second shared fixture, `tests/fixtures/kuchnia_credential.json`, asserted by both suites. Two cases carry the weight: - an **unparsable** edit time must fall back to the same clock on both sides (Python catches `ValueError` from `fromisoformat`, Dart's `tryParse` returns null). Verified they agree on `wall_time_ms == 0`; mutating that expectation fails both suites. - a **blank half** contributes nothing, so a half-filled settings form cannot push an empty-string password that wins LWW against a real one. `KuchniaCredentialService.init()` is called in the WorkManager isolate as well as `main()`. A fresh isolate has its own static state and `_syncKuchniaCredential` no-ops when the singleton is missing, so without it a background tick would neither publish this device's credential nor receive a peer's -- and on the phone the background tick is most of the syncing there is. Same class of trap as the `initSyncDeviceId()` one already documented there. `.toDouble()` came off the bank record: the fields are already `double`, so it was a no-op the analyzer flags. The field *types* are what keep the encoding byte-identical to Python's, and `kuchnia_parity_test.dart` asserts that. 654 Dart tests, 1040 Python tests, 100% Python branch coverage.
