+## Empty currency accounts (task #66)
+
+The shared empty-account message used on Accounts and transfer screens explains
+that no currency accounts have been set up and directs the customer to support
+to request setup. English and Russian no longer suggest that refreshing creates
+accounts or imply that automatic provisioning is underway. This follows the
+existing support guidance for missing funding and payout setup. The application
+has no configured support contact channel; the message therefore provides text
+guidance without a nonfunctional contact button or invented contact details.
+
+UX review: the copy names the missing resource and the next step, retains the
+existing wrapping text and accessible reading order, and does not alter loading,
+error or populated-state behavior. Existing manual refresh remains available for
+accounts provisioned externally. This copy-only change adds no controls or
+journey outcomes and requires no new analytics events. Existing transaction
+journey signals and their production measurement limitations below still apply;
+support resolution and external account provisioning are not measured in-app.
+
+Validation: `flutter gen-l10n`, `flutter analyze` in `frontend/app`,
+`make test-frontend` (217 tests), and `git diff --check` passed. No Dart source
+changed, so Dart formatting was not applicable. Existing responsive workspace
+tests cover Russian at 320px with enlarged text; this copy-only change does not
+add a dedicated empty-state rendering or native screen-reader test. No security
+scan was requested. Delivery: [task #66](https://git.sendico.io/tech/sxchnge/issues/66),
+branch `wallet-66`, [PR #68](https://git.sendico.io/tech/sxchnge/pulls/68).
+Merge and deployment remain separate.

-## Residence country selection — task #64
-
-Task [#64](https://git.sendico.io/tech/sxchnge/issues/64), branch `kyc-64`.
-Delivery: [PR #65](https://git.sendico.io/tech/sxchnge/pulls/65).
-The profile now shows a country name and opens a searchable country list instead
-of asking customers to type a two-letter code. Names follow the English/Russian
-app locale. Search accepts localized or English names and two-letter codes,
-ignoring case and surrounding whitespace. Selection updates only
-`IdentityProfile.residenceCountry` with the country code; the existing provider,
-service, mapper and transport contracts remain unchanged.
-
-The `country_picker` dependency supplies bundled country data, code lookup and
-translations through `CountryService` and `CountryLocalizations`. Flutter Material
-controls provide the search interface, explicit no-results recovery, minimum
-touch targets, keyboard selection, a selected-state checkmark, Back and Escape.
-The package's built-in list omits explicit no-results feedback and uses shorter
-row targets, so its data/localizations are reused with standard Material controls.
-There is no remote lookup, copied country table or extra application provider.
-Cancelling preserves the current profile, prefilled codes display names, busy
-state disables opening the selector, and the search controller is disposed with
-its dialog. The list is a data catalogue; backend eligibility remains authoritative.
-
-This change stays within the existing KYC preparation/submission journey and its
-measurement definitions above. No selector events, queries, names or country
-codes are added to telemetry. Existing acceptance/failure/retry/abandonment
-signals and documented server-side review measurement gaps still apply.
-
-Focused widget checks cover name/code search, code-only updates, reselection,
-cancel, no-results recovery, clearing search, saved values, locale changes,
-Russian names, disabled state, keyboard activation/selection/Escape and labeled
-touch targets. A long country name fits at 320px with 1.6 text scale. Existing
-EN/RU verification journeys now select a country and assert the profile code
-before continuing through document submission. Native screen-reader and device
-keyboard testing remain release checks; widget semantics checks do not establish
-those device outcomes.
-
-Validation: five changed Dart files passed the format check; `flutter analyze`
-in `frontend/app` reported no issues; `make test-frontend` passed all 222 tests;
-and `flutter build web` passed, including its Wasm compatibility dry run. Browser
-smoke testing on the local demo opened the selector, searched for Poland and
-confirmed that the profile displays Poland after selection. Focused and full
-journey tests verify the stored `PL` code. Generated localization/build outputs
-remain ignored and uncommitted.

-# Identity photo preview correction
-
-Task [#69](https://git.sendico.io/tech/sxchnge/issues/69), branch `kyc-69`.
-Delivery: [PR #71](https://git.sendico.io/tech/sxchnge/pulls/71).
-This frontend change builds on the [identity verification journey](kyc.md)
-and is independent of the birthday controls in task #67.
-
-## Cause and correction
-
-A synthetic valid PNG reproduced this Flutter 3.47.7 browser error:
-
-```text
-TypeError: Instance of '_UnmodifiableUint8ListView': type
-'_UnmodifiableUint8ListView' is not a subtype of type 'NativeUint8List'
-```
-
-The stack reached `Uint8ListToJSUint8Array.toJS` from CanvasKit's browser
-image decoder through `MemoryImage` and `ResizeImage`. File selection had
-successfully decoded the original typed bytes. The `Photo` constructor then
-copied them into an unmodifiable view, which was passed directly into the
-preview's web decoder. Native decoding accepted that view, hiding the bug in
-native-only tests. The generic image error builder presented the failure as a
-damaged document even though the selected bytes were valid.
-
-`PhotoPreview` now creates a native `Uint8List` copy for `MemoryImage` once per
-selected photo. The shared domain model stays immutable, and validation,
-providers, services and transport contracts remain unchanged. The preview still
-requests a decode width of at most 1000 pixels and evicts its decoded cache entry
-on replacement or disposal. The extra encoded-byte copy belongs to the preview
-and is released with its provider/cache references; no secure-erasure guarantee
-is made.
-
-An actual preview failure now says that the preview could not be displayed and
-suggests selecting the photo again. The English/Russian fallback keeps at least
-the preview's usual height, can grow for long text, and has a separate live-region
-semantic node. Existing replacement/removal controls stay available and selected
-input is retained. This is distinct from validation's corrupt-file message.
-
-## UX and measurement review
-
-The outcome remains selecting readable ID and selfie photos, checking both on
-review, and submitting for confirmed service acceptance. Existing KYC journey
-attempts, retries, failure, submission and abandonment signals are reused. No
-control-level events, image bytes, filenames, form values or raw exceptions are
-added to telemetry. A selection success measures validation; it does not establish
-that pixels were painted. Preview-only rendering failures are not separately
-counted by existing telemetry. Server review/approval measurement and native
-screen-reader QA retain the limitations documented in the original journey.
-
-Regression tests use synthetic JPEG/PNG content only. They start and await real
-image decoding outside the widget test's fake async zone, inspect the actual
-rendered images, and surface stream errors so an error fallback cannot conceal a
-failure. Checks cover portrait/landscape decoding, model immutability, bounded
-decode width, stable provider reuse, replacement/removal cache eviction, both
-review slots, returning to review, localized fallback/replacement, a 320px view
-at 1.6 text scale, and error announcements isolated from surrounding instructions.
-The `image` package is already a KYC runtime dependency; its direct app test
-dependency is used only to create synthetic fixtures in memory.
-
-## Validation and delivery
-
-The original browser regression failed before the fix while its native equivalent
-passed. The complete task diff was reviewed against frontend architecture, UX,
-measurement, lifecycle and privacy requirements. Final validation passed:
-
-- In `frontend/app`, `dart format --output=none --set-exit-if-changed
-  lib/kyc/preview.dart test/preview_test.dart`: two files, no changes.
-- In `frontend/app`, `flutter analyze --no-pub`: no issues.
-- In `frontend/app`, `flutter test --platform chrome test/preview_test.dart
-  --reporter expanded --no-pub --verbose`: all six regression tests passed.
-- At the repository root, `make test-frontend`: all 228 tests passed across
-  the shared packages, theme example and app, including the six native preview
-  regressions and existing KYC journey/analytics tests.
-- In `frontend/app`, `flutter build web --no-pub`: release build and Wasm
-  compatibility dry run succeeded.
-
-Browser regression coverage uses Chrome; Safari and native assistive-technology
-testing remain release checks. Generated localization and build code stays
-ignored; the tracked app lockfile changes only `image` from transitive to direct
-test dependency. The separate birthday worktree was preserved.
