+# Launches the official BitBox02 simulator
+# (https://github.com/BitBoxSwiss/bitbox02-firmware/releases) and runs
+# the bitbox-testkit baseline scenarios against real firmware logic.
+#
+# What this validates for realunit-app:
+#   • bitbox-api ↔ BitBox02 firmware Noise handshake round-trip.
+#   • ETH-address derivation on chainId=1 AND chainId=137 (the
+#     multi-byte-v boundary that has historically broken EIP-155
+#     consumers).
+#   • ETH personal-message signing at the firmware-doc 1024-byte upper
+#     boundary.
+#   • EIP-1559 sign happy path.
+#
+# What this does NOT validate: realunit-app's Dart code talking to
+# the BitBox via the bitbox_flutter plugin against real hardware.
+# That still requires a physical BitBox02. The simulator covers the
+# FIRMWARE side of the protocol; the Dart consumer side is exercised
+# by Tier 1 (SDK-boundary fake, cross-layer tests under
+# `test/integration/`) and ultimately by Tier 3 Maestro flows on
+# real hardware. See `docs/testing.md` for the five-tier model and
+# issue #314 for the rollout plan. The pinned bitbox_flutter version
+# lives in `pubspec.yaml`.

+# branch manually.

+# Trigger model:
+#  - `pull_request` fires on every PR regardless of target branch,
+#    EXCEPT PRs targeting `main`. Stacked PRs (feature → integration
+#    → develop) need their own CI run so a regression is caught at
+#    the lowest possible level, not only after the stack has been
+#    collapsed to a develop PR. Release PRs (develop → main, opened
+#    automatically by `auto-release-pr.yaml`) are deliberately
+#    excluded: `push: develop` already covered the same SHA when the
+#    commit landed, and concurrency groups don't dedupe across
+#    push-vs-pull_request events, so allowing both would double
+#    macOS-runner load on the release lane for no signal.
+#  - `ready_for_review` makes the workflow fire the moment a draft PR
+#    is marked ready — drafts themselves skip via the `if:` guard
+#    below (saves macOS-runner minutes while work is still in progress).
+#  - `labeled` / `unlabeled` are intentionally omitted: realunit-app has
+#    no label-gated heavy job here (Tier 3 has its own workflow).
+#  - `push: develop` and `push: staging` keep post-merge verification
+#    as an authoritative source of truth, independent of any PR state.
+#    `staging` participates because feature → staging merges land an
+#    integration commit whose verification cannot be deferred to the
+#    auto-opened staging → develop PR (the gate must be authoritative
+#    at the moment the commit lands on staging). Other branches do not
+#    need a post-push check — the PR-event already covers them.
+#  - `workflow_dispatch` is kept as a manual override and is NOT
+#    draft-gated (see the job `if:` guard below).

+  # Lives in its own job (not inline in `Analyze & Test`) so it can be set
+  # as a separately required status check in branch protection — a single
+  # job name on `Analyze & Test` would let the floor regress without

+  #   build  ─►  coverage-floor       (sequential; needs the summary artifact)
+  #   build  ║   bitbox-audit          (parallel; informational only)
+  #
+  # Ratchet protocol (also documented under README "Coverage infrastructure
+  # roadmap"):
+  #   * Raising the floor is encouraged on every PR that raises measured
+  #     coverage — bump the file in the same commit and the gate moves up.
+  #   * Lowering the floor needs a reviewer's explicit OK. PR convention is
+  #     the `coverage:lower-floor` label so the regression is visible at
+  #     a glance in the PR list rather than being smuggled in.
+  #
+  # Why pure bash + awk instead of `lcov --fail-under-*`:
+  #   the `--fail-under-lines` flag arrived in lcov 2.0 and earlier runner
+  #   images may still pull 1.x out of the package manager. Comparing
+  #   `52.9` against `51` with awk sidesteps that and stays portable.
+  #
+  # On the "no data found" path for the functions metric:
+  #   `flutter test --coverage` emits LF/LH (line execution) and BRF/BRH
+  #   (branch) records, but not FN/FNF/FNH (function execution) — that's a
+  #   Flutter limitation, not a repo bug. When the summary reports
+  #   "no data found" for functions, the gate emits a workflow warning
+  #   instead of comparing against an empty value. This is intentionally
+  #   NOT a silent skip: the warning surfaces in the run summary so a
+  #   future Flutter release adding FN records doesn't go unnoticed (and
+  #   the floor file stays committed so the gate activates the moment
+  #   real data appears).
+  #
+  # On the missing `coverage/lcov.summary` path:
+  #   the gate fails CLOSED with `exit 1`. Previously this was a silent
+  #   `exit 0` warning, which made the gate effectively advisory — a broken
+  #   upstream filter (e.g. lcov.info missing, brew install failure) would
+  #   skip the gate without anyone noticing. The new behaviour is: if
+  #   `Analyze & Test` did not produce a summary, the gate is red, the PR
+  #   is blocked, and the reviewer sees exactly where the pipeline broke.

+name: Tier 3 — Handbook flows
+
+# Drives every `.maestro/handbook/*.yaml` flow against a freshly-erased iOS
+# Simulator and uploads the per-flow diagnostic captures as a build artifact
+# for forensic inspection on assertion failure (pixel drift is owned by the
+# Visual Regression job — see "Why no pixel-diff here" below). Tier 3 in the
+# five-tier model defined in `docs/testing.md`: real BitBox hardware is
+# explicitly out of scope here — the handbook flows only need the software
+# wallet path, so a hosted macOS runner is enough.
+#
+# Trigger model:
+#   * `pull_request` (any target branch) with a `tier3:full` label gate.
+#     macOS runner minutes are scarce; running on every PR would dwarf
+#     the existing Analyze & Test job. Reviewers opt-in by labelling
+#     the PR. The label gate is the cost control, not the branch
+#     filter — stacked PRs against integration branches need the same
+#     opt-in option.
+#   * `push: develop` always runs — post-merge verification is the
+#     authoritative source of truth for "did the handbook flows survive
+#     this merge", independent of any PR state. Same reasoning as
+#     `pull-request.yaml`.
+#   * `workflow_dispatch` for manual catch-up runs and a re-run path when
+#     the macOS image flips an Xcode default and we need to verify the fix
+#     before re-arming the gate. Always runs (label gate doesn't apply).
+#   * `labeled` / `unlabeled` keep the trigger surface in sync with the
+#     `tier3:full` opt-in: adding the label after the PR opened starts a
+#     run; removing it cancels via the concurrency block below.
+#
+# Concurrency:
+#   Same pattern as `pull-request.yaml`: group by `pull_request.number`
+#   (or `github.ref` for push/dispatch) so a new push to the same PR
+#   cancels the in-flight run. Grouping by SHA (the previous approach)
+#   put every commit in its own group, which meant no cancellation
+#   ever happened and back-to-back pushes queued sequentially on
+#   scarce macOS runners. The exception: `labeled` / `unlabeled` events
+#   get their own `ci-<workflow>-label-<run_id>` group so a label toggle
+#   does NOT kill an already-running ~15-minute flow execution — the user
+#   experience of "I added the label, the previous run died" is worse
+#   than the cost of one extra runner-minute.
+#
+# Locale: scripts/run-handbook-flows.sh pins the booted simulator to de_CH
+# so German handbook assertions pass on `macos-latest` runners (default
+# en_US). Local re-captures inherit the same locale → screenshots stable.
+#
+# Why `simctl erase` per run (not `clearState`):
+#   `scripts/run-handbook-flows.sh` already does this, but worth restating
+#   here because it drives the choice of macOS runner. The wallet seed and
+#   PIN live in the iOS Keychain, which survives both Maestro `clearState`
+#   and an app reinstall. A booted simulator from a prior run would start
+#   on the lock screen instead of the welcome flow, breaking every
+#   assertion downstream. `simctl erase` wipes the whole device — the
+#   only known-good clean-state for this purpose.
+#
+# Maestro version pin:
+#   Maestro 2.3.0–2.5.1 has two intermittent failure modes on Apple
+#   Silicon + iOS 26.x simulators: (a) XCUITest driver hangs during
+#   startup with zero stdout, (b) `tapOnElement` reports completed but
+#   the Flutter app never receives the touch event (verified via
+#   Maestro `--debug-output`: captured screenshot shows unchanged
+#   screen after tap). Both regressions tracked upstream in
+#   mobile-dev-inc/maestro#3137 (closed by upstream with the 2.0.10
+#   workaround). We pin via `.maestro-version` (today: `2.0.10`),
+#   which per the #3137 thread runs ~20 sequential flows reliably
+#   with ~10 % residual Apple-XCTest crash on screen transitions.
+#   The retry loop in `scripts/run-handbook-flows.sh` stays in place
+#   as a safety net for that residual crash class, retrying only on
+#   `IOSDriverTimeoutException` — assertion failures are never
+#   retried. The post-mortem block (lsof / ps / simctl log + Maestro
+#   `--debug-output`) captures failure state so future regressions
+#   can be diagnosed forensically. The CI-hardening track that landed
+#   this guard was DFXswiss/realunit-app#487 (now closed).
+#
+# Why no pixel-diff here:
+#   Pixel drift on the page renders is owned by the Visual Regression job
+#   in `pull-request.yaml` (alchemist Goldens on the dfx01 hardware-pinned
+#   runner). Tier-3 catches the regressions Goldens cannot see — broken
+#   tap routing, missing navigation, locale/`Intl` problems, iOS-build
+#   and `simctl install` failures. The per-flow `assertVisible` /
+#   `extendedWaitUntil` covers those structural modes; the diagnostic
+#   captures under `build/handbook-captures/` are forensic artefacts for
+#   assertion failures, not a screenshot baseline.
+#
+# Why `iPhone 17` specifically:
+#   The `.maestro/handbook/*.yaml` flows use absolute tap points (e.g.
+#   `point: 50%,65%`) and assertions on text that sits inside the
+#   iPhone-17 safe-area layout. Any other device class would either
+#   reflow elements out of the tap-coordinate path or shift safe-area
+#   insets in a way that breaks the assertions. When the macOS runner
+#   image stops shipping iPhone 17 by default, bump this here AND
+#   re-verify all 26 flows on the new device (run
+#   `scripts/run-handbook-flows.sh` locally; assertion failures point
+#   at flows that need their coordinates / waits updated).
+#
+# Cross-reference: README "CI/CD" table + `docs/testing.md` Tier 3 entry.

+# Continues from 22-settings-dfx-documents (no clearState). The DFX-documents
+# sub-page is pushed on top of SettingsLegalDocumentsPage, which in turn sits
+# on the Settings menu. We tap back twice to return to the Settings menu, then

+#
+# Settle target: the AppBar title "Kontakt" is visible WHILE
+# "Wallet-Adresse" (a settings-menu-only tile, not present on the contact
+# page) has disappeared. This combination uniquely identifies the contact
+# page without depending on `/v1/company-info/RealUnit`.
+#
+# Why NOT settle on "info@realunit.ch":
+#   The email tile is rendered from `state.companyInfo.email` in
+#   SettingsContactCubit (PR #499), which fetches `/v1/company-info/RealUnit`.
+#   That endpoint currently returns 404 on both api.dfx.swiss and
+#   dev.api.dfx.swiss — the backend side of #499 is not yet deployed. The
+#   cubit swallows the company-info error (`catchError -> null`) so the page
+#   still renders, but the email/phone/website/imprint tiles all collapse to
+#   `SizedBox.shrink()`. Asserting on the email string therefore times out
+#   even though the page navigation itself succeeded. The Support tile is
+#   also unreliable as a target: it only renders when
+#   `UserCapabilitiesDto.supportAvailable` is true, which defaults to false
+#   for freshly-created handbook wallets.
+#
+#   Once the backend exposes `/v1/company-info/RealUnit`, this flow can be
+#   tightened back to assert on the email tile — see PR #515 for context.
+#
+# The first back tap gates on "Dokumente der Aktionariat AG" — that tile lives
+# on SettingsLegalDocumentsPage but not on the DFX sub-page, so it cleanly
+# marks arrival at the legal-documents list. ("Dokumente der DFX AG" would not
+# work here: it is also the title of the DFX sub-page we are leaving.)

+# Continues from 24-settings-delete-wallet (no clearState): the
+# SettingsConfirmLogoutWalletSheet modal is showing. We complete the
+# termination here — tick the "Ich habe meine Wiederherstellungsphrase
+# gesichert." checkbox (which enables the disabled "Abmelden" button), then
+# tap "Abmelden". Confirming the logout wipes the wallet and drops the app
+# back to onboarding (welcome).
+#
+# From there we walk the restore path: from the HomePage splash tap "Start"
+# -> WelcomePage, tap the Software-Wallet card to flip the welcome toggle
+# to step 2, then tap the Wallet-wiederherstellen card -> RestoreWalletPage.
+# The settle target is the seed-entry description text, which is unique to
+# RestoreWalletView (the "Wallet wiederherstellen" heading shares its string
+# with the welcome card and would match too early).
+#
+# Welcome cards are targeted by Semantics id (see
+# lib/screens/welcome/welcome_page.dart) instead of regex text-matching of
+# their titles. Both step groups stay in the widget tree at all times —
+# AnimatedSlide translates the off-screen group out of view but doesn't
+# remove it from the semantic tree — so regex text checks against card
+# titles match off-screen widgets and break `notVisible` gates. The id
+# targets are stable across copy refreshes and animation half-states, and
+# use the same pattern as the `wallet-logout-confirm-checkbox` and
+# `home-terms-link` Semantics ids elsewhere in the app.
+#
+# The checkbox is now wrapped in `Semantics(identifier:
+# 'wallet-logout-confirm-checkbox', toggled: …)` with a row-wide opaque
+# GestureDetector (see
+# lib/screens/settings/widgets/settings_confirm_logout_wallet_sheet.dart)
+# so Maestro can target it deterministically via `tapOn: id:` instead of the
+# previous wrap-sensitive `leftOf:` coordinate-tap that XCUITest silently
+# dropped on Apple Silicon + iOS 26 (mobile-dev-inc/maestro#3137) — that
+# silent loss is what caused the prior run to never check the box, leaving
+# "Abmelden" disabled and every downstream step a no-op against the still
+# visible modal. We tap the checkbox once by id (a single deterministic
+# Semantics target with a full-row tap surface), then gate the "Abmelden"
+# button tap on the modal still being visible — if "Abmelden" was silently
+# dropped we re-tap until the modal closes. We deliberately do not loop the
+# checkbox itself: tapping it twice would toggle it back off again, since
+# the underlying `setState(() => isChecked = !isChecked)` is not idempotent.
+# If the checkbox tap is the one that's silently dropped, the next
+# `extendedWaitUntil notVisible "Aus REALU Wallet abmelden"` (with the
+# Abmelden button still disabled) fails loudly rather than passing silently
+# downstream — and the same Semantics-id strategy that fixed flow 26's
+# Nutzungsbedingungen-link tap has been reliable enough since.
+#
+# All tap-leading steps (Abmelden, Start, Software-Wallet, Wallet
+# wiederherstellen) are gated on their target not yet showing and re-tapped

+## Branch Flow
+
+Three branches participate in the release lane:
+
+- `staging` — integration branch. **All feature PRs target `staging`**, not `develop`. Same protections as `develop`: 1 approval + `Analyze & Test` + `Visual Regression` + `Coverage Floor Gate`.
+- `develop` — pre-release. Receives changes via [`auto-staging-pr.yaml`](.github/workflows/auto-staging-pr.yaml), which opens a `staging → develop` PR on every push to `staging`.
+- `main` — production. Receives changes via [`auto-release-pr.yaml`](.github/workflows/auto-release-pr.yaml), which opens a `develop → main` PR on every push to `develop`.
+
+```
+feature/* ──(PR)──> staging ──(auto-PR)──> develop ──(auto-PR)──> main
+```
+
+The auto-opened promotion PRs are idempotent — only one is open per branch pair at any time. Each one waits for the same review + CI gates as the underlying branch. Tagged releases (`v*`) trigger after the relevant branch receives the commit; see the Release Versioning workflow table in the README for details.
+
 ## API Access — CRITICAL
 
 - The app is **only allowed to talk to the DFX API**: `api.dfx.swiss` (mainnet) and `dev.api.dfx.swiss` (testnet/Sepolia). No other hosts.
@@ -19,6 +34,78 @@ After changing ARB files, always regenerate: `dart run tool/generate_localizatio
 - If a feature needs on-chain data (e.g. native ETH balance, transaction status, token balance), add a new endpoint to [`DFXswiss/api`](https://github.com/DFXswiss/api) and let the app call that endpoint. The API is the single gateway.
 - All network calls must go through `AppStore.httpClient` with `buildUri(_host, …)` — `_host` resolves to the DFX API host via `ApiConfig`. Do not instantiate `http.Client`/`Dio`/`Web3Client` against other hosts.
 
+## API as Decision Authority — CRITICAL
+
+Network access is one half of the gateway rule. **Business decisions are the other half.** The DFX API is the single source of truth for what the user is allowed to do, what state they are in, and what they should be asked to do next. The realunit-app is a **rendering layer** for what the API says.
+
+### The rule
+
+- **The app does not decide if a flow is allowed.** The API decides. If the API accepts a call, the app must not block it pre-emptively.
+- **The app does not interpret status strings into business meaning.** It renders what the API returns as `currentStep` / `nextAction` / `state`.
+- **The app does not duplicate backend sets/enums as gating logic.** DTO mirroring for type safety is fine; local `_requiredStepNames`, `actionableStatuses`, `_minLevelForActions`, `_minAmountChf` constants are not.
+- **Prompts to the user fire only when the API requests them.** "Please verify yourself" appears only when the API signals a pending KYC step — never because the app inferred something from a level number or expired timestamp.
+
+### The test (Wer entscheidet?)
+
+Before adding an `if` / `switch` / `.filter()` on API data, ask:
+
+1. Does the API already return the answer I'm computing? → use it directly.
+2. If I remove this local logic and render the API field 1:1, what breaks? → if "nothing", remove it; if "a missing field", extend the API.
+3. When local and API disagree, who wins? → the API. Always.
+
+### What is OK in the app
+
+- UI input validation (format, required field, length) — UI concern
+- Display formatting (date, currency, locale) — UI concern
+- Local security gates (PIN, wallet lock, BitBox connection) — physical security boundary, cannot be API-driven
+- Cryptographic operations (EIP-712 signing, key derivation) — must be local
+
+### What is NOT OK in the app
+
+- Deciding which KYC steps are required (`_requiredStepNames`, `_minLevelForActions`) — **the API decides via `requiredKycSteps()` on its side**
+- Deciding which step status is "actionable" or "pending" (`actionableStatuses`, `pendingStatuses`) — **the API returns `currentStep` directly**
+- Min/max transaction amounts, fees, supported currencies hardcoded — **must come from `/quote` / `/fiat` / `/asset` endpoints**
+- Routing flows based on local conditions (`if isBitbox → sellBitbox`) — **API signals the required workflow**
+- Feature visibility based on derived local state (Support link only if `emailSet`, Edit only if `!inReview`) — **API returns capability flags**
+- Pre-flight validation duplicating API rules — **call the API, render its error**
+
+### When the API doesn't yet expose what we need
+
+Extend the API, then change the app. **Do not add app-side workarounds.** Open an issue / PR in [`DFXswiss/api`](https://github.com/DFXswiss/api) describing the missing field (e.g. `KycStepDto.isRequired`, `BuyQuoteDto.minAmount`, `SettingsCapabilityDto.canBackup`) and wait for it. Temporary local logic is technical debt that **stays** — every shortcut accumulates as another place the app diverges from the API.
+
+### Audit
+
+A full audit of current violations lives in [`docs/api-authority-audit.md`](docs/api-authority-audit.md). New PRs must not add to it; ideally they reduce it.
+
+### Consuming API capabilities — eight rules
+
+When the API exposes a capability (boolean flag or struct on `UserCapabilitiesDto` / similar), the app's consumer code follows the rules below. The mirror — the rules for how the API exposes capabilities — lives in [`DFXswiss/api:CONTRIBUTING.md`](https://github.com/DFXswiss/api/blob/develop/CONTRIBUTING.md) under "API Capability Design". Both sets were synthesised from the `#3733 → #3761 → #3767(closed) → #3772(merged 2026-05-26)` review sequence with @davidleomay.
+
+1. **Read the capability shape, don't reconstruct it.** If the API ships `canEditName: bool`, the page binds `onPressed` to `canEditName`. If it ships `createSupportTicket: { available, missingPrerequisite? }`, the tap handler routes on the discriminator. Never `if (user.mail == null)` or `if (user.kyc.level >= 30)` as a stand-in.
+
+2. **Tile/button visibility for discoverable actions is unconditional.** Tiles that gate prerequisites (Support, KYC, etc.) stay visible regardless of capability state — the user discovers the action even pre-signin. The capability struct's `available` field controls only the **tap outcome** (push the target page vs. push the prerequisite capture page), not the **visibility**.
+
+3. **Map prerequisite types to UI components, not to business rules.** When the capability says `missingPrerequisite: 'Email'`, the app pushes the email capture page. It does NOT contain a comment like "this means mail is required because support needs it" — the rule is on the backend. The app's switch is a UI dispatch, not domain logic.
+
+4. **Legacy backend tolerance — capability optional, sane fallback.** All new capability fields are nullable in the Dart DTO (`createSupportTicket?: CreateSupportTicketCapabilityDto`). On pre-rollout backends the field is null; the consumer falls back to the unprotected direct-push. The behaviour is identical to today's behaviour (pre-capability), so the user is no worse off — the capability just adds the smarter path when the backend supports it.
+
+5. **No reactive 400-handling for what a capability could pre-tell.** If the backend exposes a pre-tap capability, the app must consume it. Attempting the action and reacting to a typed `BadRequestException` post-submit is a regression — the user loses form data, the error-body parsing is brittle, the navigation choreography is fragile. Reactive errors are only for things the capability can't predict (network failures, transient backend issues, race conditions).
+
+6. **Pair-PR discipline.** App-side capability adoption happens in the same PR that deletes the local logic the capability replaces. PR title: `refactor(<scope>): consume <Capability>`. PR body cites the V-ID from `docs/api-authority-audit.md` and the API-side commit. The PR is opened **after** the API PR has merged on `develop` — running ahead of the API merge means the consumer sees null forever in DEV and the change effectively dead-codes itself.
+
+7. **Tests pin the contract, not the implementation.** Cubit tests assert that `init()` with `capability == null` emits the legacy-fallback success state; with `available: true` emits the available state; with `available: false, missingPrerequisite: Email` emits the prerequisite-required state. Widget tests assert that taps in each state push the correct route. Don't test "if mail == null, the tile state is unavailable" — that ties the test to the backend rule, exactly what we're trying to decouple.
+
+8. **Push back on capability shape that's over-engineered.** Capabilities should be the minimum dynamic info to fulfil a UX requirement. Endpoint paths, HTTP methods, and i18n strings belong in Swagger / the client respectively. If a proposed API field looks like it duplicates static information, comment on the API PR asking for the minimum surface. Reference template: <https://github.com/DFXswiss/api/pull/3772#issuecomment-4549147861>.
+
+#### Concrete pattern — Support ticket flow
+
+The first capability that follows this design lives end-to-end across these PRs:
+
+- API: [DFXswiss/api#3772](https://github.com/DFXswiss/api/pull/3772) — adds `createSupportTicket: { available, missingPrerequisite? }`.
+- App: companion PR on this repo consuming the field — `SettingsContactPage` keeps the tile unconditional, `SettingsContactCubit` hydrates the capability from `/v2/user`, the tap handler in the view routes on `capability.available` / `capability.missingPrerequisite`.
+
+Future capabilities follow the same shape: bool for hide-able, `{ available, missingPrerequisite? }` for discoverable. The closed `MissingPrerequisite` enum grows additively as new prerequisite gates appear server-side.

 - Before adding a new key: search existing keys first — reuse where possible.

+## Release Versioning
+
+- Single source of truth for a published build: the git tag. Tags are plain SemVer `vX.Y.Z` — no pre-release suffix. The previous `vX.Y.Z-beta.N` schema has been retired and tags carrying any suffix are rejected by the generator.
+- PATCH (`v1.0.X`, X >= 1) is bumped automatically by `.github/workflows/auto-tag.yaml` on every push to `develop`. MINOR / MAJOR are manual tag pushes — they mark an App-Store-update candidate.
+- Both release workflows ship to Test tracks only (TestFlight + Play Internal). Production promotion is done manually in the store backends, never by a tag push.
+- `tool/generate_release_info.dart` derives the in-app `releaseTag`, the platform-identical `versionCode` and the `marketingVersion` from the tag. Schema: `MAJOR * 10_000_000 + MINOR * 100_000 + PATCH * 1_000 + 999`. The fixed `+999` suffix keeps new build codes strictly above the legacy beta train (highest published was `v1.0.0-beta.14` → `10_000_014`).
+- Local builds carry `releaseTag = 'dev'` (versionCode `0`) so the settings footer reads `Version dev` instead of a stale pinned build number.
+- `pubspec.yaml`'s `version:` field has two roles:
+  - `+0` is a sentinel for local builds — CI always overrides `--build-name` / `--build-number` from the tag. Don't bump the `+N` part manually.
+  - The `X.Y.Z` part is consumed by `auto-tag.yaml` as a **floor** for MAJOR / MINOR bumps. Patch increments come from the latest tag; pubspec is only consulted to trigger jumps. To start a new MINOR / MAJOR train (e.g. `1.1.0`), bump the `X.Y.Z` part in `pubspec.yaml` on `develop` and the next auto-tag will pick it up. Patch-level work needs no edit — just push to develop.
+- Schema limits: `MAJOR`, `MINOR`, `PATCH` in `0..99`. The generator hard-fails outside these bounds. Before approaching `PATCH = 99` on a given train, bump `pubspec.yaml`'s MINOR (e.g. `1.0.99` → `1.1.0`) so auto-tag starts a new train. There is intentionally no safety net — surprising a CI cap is preferable to silently overflowing the version code.
+
+See the README's "Release versioning" section for the full table and the typical patch flow.
+
 ## State Management
 
 - **Bloc**: For complex event-driven flows. Events are `sealed class` extending `Equatable`. States use `final class` — use `copyWith` or distinct state classes (Initial, Loading, Success, Failure) depending on the use case.
 - **Cubit**: For simpler state. States extend `Equatable` — use `copyWith` or distinct state classes depending on the use case.
 - State files are separate from bloc/cubit files.
 
+## Wallet Modes
+
+The app supports three wallet modes (`software`, `bitbox`, `debug`) with different signing capabilities. Any feature that needs an EIP-712 signature must gate on `getIt<AppStore>().wallet.walletType` and surface a dedicated failure state for modes that cannot sign (today: `debug`). See [`docs/wallet-modes.md`](docs/wallet-modes.md) for the full table and the `KycSignatureUnsupportedFailure` precedent.

 - Test structure mirrors `lib/` structure.
 - Test helper at `test/helper/` (provides `pumpApp`).
+- For BitBox-related code, the layered test strategy (Tier 0–4) is documented in [`docs/testing.md`](docs/testing.md), with concrete patterns for cubit tests, widget tests, service + HTTP tests, and `FakeBitboxCredentials`-backed integration tests.
+- [`docs/testing.md`](docs/testing.md) also lists the surface that needs an infra PR first (Drift repositories, `getIt`-coupled pages, `path_provider`-coupled cubits, the Sumsub SDK, plugin-coupled widgets). Don't try to mock around those without changing the injection point.
+- Service-lifecycle tests are mandatory for any service with a `Timer`, observer/subscription loop, or platform/MethodChannel dependency: instantiate the real class (no mock of the service itself), swap `BitboxUsbPlatform.instance` in `setUp` and restore in `tearDown`. Tests with periodic-timer or observer behaviour MUST drive time via `package:fake_async` (`fakeAsync` zone + `async.elapse(...)`). Wall-clock `Future.delayed` is not acceptable for time-bound assertions.
+  - Why: mocking the service-under-test hides timer leaks, unsubscribed listeners, and double-init bugs; wall-clock delays make tests slow and flaky.
+  - See: `test/packages/hardware_wallet/bitbox_service_test.dart`.
+- Exception surface tests are mandatory: every typed exception in `lib/` (any class that `implements Exception` or `extends Exception`) MUST override `toString()` so the rendered string does not contain `Instance of` and is non-empty, AND MUST be enumerated in the shared surface test the moment it is introduced. When a new typed exception is added to `lib/`, it MUST be added to the enumeration in `exception_surface_test.dart` in the same PR. The test exists to catch precisely this kind of drift.
+  - Why: exceptions surface in logs, Sentry, and user-facing error states — the Dart default `Instance of '...'` is useless for debugging and unfriendly for users.
+  - See: `test/packages/service/dfx/exceptions/exception_surface_test.dart`.
+- Platform-specific code paths (USB transports, BLE lifecycle, secure storage, biometric prompts, deep links) MUST either ship an `integration_test/` counterpart exercising the real plugin or vendor simulator, OR carry an inline `// @no-integration-test: <reason>` annotation as either a file-level dartdoc comment OR immediately above the function/method declaration.[^integration-test]
+  - Why: unit tests with mocked platform channels cannot catch real-device regressions (permission prompts, OS-level lifecycle, transport quirks); the annotation makes the absence of an integration test a deliberate, reviewable decision.
+  - See: grep the annotation with
+    ```bash
+    rg "^//\s*@no-integration-test:" lib/
+    ```
+- Visual-regression Goldens under `test/goldens/screens/` are also the source of the 26 screenshots served at `handbook.realunit.app`. When you add a handbook page, you MUST add a matching Golden test AND a row in the mapping table at `scripts/assemble-handbook-screenshots.sh` — the handbook will not pick up a Maestro-captured PNG anymore. The `Handbook Build Check` workflow on every PR runs the assembly script and fails loudly if a mapped Golden is missing.
+  - Why: single source of truth — a UI regression that breaks a Golden also breaks the handbook image before either ships; eliminates the previous "two pipelines, two truths" problem.
+  - See: [`docs/visual-regression-tests.md`](docs/visual-regression-tests.md) section "Handbook screenshots are sourced from Goldens".

-## Getting Started
+> **Status:** Early development. APIs, flows and UI are still moving.
+
+## Contributing
+
+**New PRs may only merge into `develop` if test coverage is 100% on the activated surface.** Concretely:
+
+- `flutter test --coverage` must report 100% lines / functions / branches on every file in the activated surface (see Coverage scope below). CI will fail the build below threshold.
+- Defensive code that genuinely cannot be reached in `flutter_test` (platform channels without a test override, native plugin entry points, BLE callbacks) is exempted by an inline `// coverage:ignore-line` annotation with a one-line reason.
+- The branch is protected on GitHub: a PR cannot be merged while CI is red.
+
+**Coverage scope:** `lib/packages/**` (services, repositories, signers, utils) and the `cubits/` + `bloc/` directories under each `lib/screens/<feature>/`. Widget files (`lib/screens/<feature>/<feature>_page.dart` and `lib/widgets/**`) are exercised via `testWidgets` specs and excluded from the line-coverage gate — widget tests count as `widget` coverage in the feature matrix, not as line %. Generated files (`*.g.dart` from `build_runner` / Drift) are also stripped after the scope extract — they are tool output, not developer code, and would otherwise drag the scoped line % down for free.
+
+The five-tier testing model (Tier 0 Cubit unit · Tier 1 FakeBitbox integration · Tier 2 firmware simulator · Tier 3 Maestro flows (handbook simulator + deferred BitBox02 hardware) · Tier 4 BLE VCR/replay stretch) is tracked in [#314](https://github.com/DFXswiss/realunit-app/issues/314). See [`docs/testing.md`](docs/testing.md) for the full tier picker. New BitBox-touching PRs are expected to add tests at the appropriate tier(s).

+- [x] `flutter test --coverage` step in `.github/workflows/pull-request.yaml`
+- [x] lcov filter narrowed to the activated surface (`lib/packages/**` + `lib/screens/**/cubit(s)/**` + `lib/screens/**/bloc/**`) and a per-run summary posted to the workflow step summary
+- [x] lcov threshold check failing the build below a committed floor on the scope above
+- [x] Floor gate lives in its own CI job (`Coverage Floor Gate`), wired up as a required status check on `develop` + `main`
+- [x] GitHub branch protection on `develop` requiring the `Coverage Floor Gate` check (ruleset `PRs` / id `11317379`)
+- [x] Inline `// coverage:ignore-*` annotations on truly unreachable paths, each with a one-line reason — applied to Drift schema getters across `lib/packages/storage/`, defensive `assert(false) → throw StateError` fallthroughs in `wallet.dart`, `BitboxCredentials` sync entry points that only exist to satisfy the web3dart interface, the platform-channel forwarders in `PathProviderAdapter` and `BiometricServiceAdapter`, and the `_localTesting` dev-only `Uri.http` branch in `api_config.dart`
+
+**Ratchet protocol.** The committed floor lives in two flat files at the repo root: `.coverage-floor-lines` and `.coverage-floor-functions` (integer percent, no `%` suffix). CI fails the build when scoped coverage drops below either value. Raising the floor is encouraged on every PR that raises measured coverage — bump the file in the same commit and the gate moves up. Lowering the floor requires explicit reviewer sign-off; PR convention is the `coverage:lower-floor` label so the regression is visible in the PR list rather than smuggled in. The functions floor is parked at a placeholder today because `flutter test --coverage` does not emit `FN` records — the gate warns instead of failing on that metric until upstream adds support.
+
+> **Before first use:** two PR labels are referenced by this tooling but are not auto-created. Run `gh label create tier3:full` once on the repo to enable per-PR opt-in for the Tier 3 handbook workflow — without the label the workflow's `if:` gate never matches and the job silently skips on PRs. Run `gh label create coverage:lower-floor` once to make floor-lowering PRs grep-able; the coverage floor gate itself runs unconditionally on every PR, this label is a review-convention marker only and is not read by any workflow.
+
+Three PRs have closed the largest gaps for KYC + BitBox logic: [#319](https://github.com/DFXswiss/realunit-app/pull/319) (Tier 0 cubit tests), [#320](https://github.com/DFXswiss/realunit-app/pull/320) (Tier 1 FakeBitbox integration), [#321](https://github.com/DFXswiss/realunit-app/pull/321) (dashboard buy actions + auth service tests).

+## Features
+
+User-facing functions, their activation status, and the tests that cover them. It is the source of truth for "what does this wallet actually do" — keep it in sync when adding or removing a flow.
+
+**Status legend:** `always` = ships on every build · `hardware` = needs a BitBox hardware wallet (see [Supported hardware wallets](#supported-hardware-wallets) below) · `planned` = surface exists but flow not yet implemented.
+
+**Triage legend** (MVP testing decision): `mvp` = in MVP scope, must reach full test coverage before launch · `defer` = ships but does not block MVP coverage (coverage required eventually, no hard deadline) · `planned` = not in scope for MVP.
+
+**Tests legend:** `widget` = `testWidgets` spec under `test/screens/**` · `golden` = visual-regression spec under `test/goldens/**` (pixel-exact baseline rendered on the dfx01 self-hosted runner, see [`docs/visual-regression-tests.md`](docs/visual-regression-tests.md)) · `unit` = pure-Dart `test/packages/**` spec · `cubit` = `bloc_test`-style spec for a Bloc/Cubit · `integration` = `test/integration/**` spec crossing ≥ 2 production layers with `FakeBitboxCredentials` · `e2e` = Maestro YAML flow on real hardware · `—` = no test exists.
+
+> Per-feature line-coverage % is not surfaced in this table. The repo-wide scoped coverage is enforced by the `Coverage Floor Gate` CI job against `.coverage-floor-lines` / `.coverage-floor-functions`; the lcov artifact attached to every PR run holds the per-file breakdown.
+
+### Supported hardware wallets
+
+`hardware`-status flows require a BitBox device. Platform availability depends on the model:
+
+| Device | Android | iOS |
+| --- | --- | --- |
+| BitBox 02 | yes | no |
+| BitBox 02 Nova | yes | yes |
+
+The transport is USB on Android and Bluetooth on iOS; the original BitBox 02 has no Bluetooth, so iOS support requires a BitBox 02 Nova.

+## Triage gaps
+
+The activated surface (see "Coverage scope" above) is at **100 % scoped line coverage**. Every file under `lib/packages/**`, `lib/screens/**/cubit(s)/**`, and `lib/screens/**/bloc/**` either ships with tests or carries an `// coverage:ignore-*` annotation with a documented reason. The previous bullet list of partially-covered services, KYC cubits, biometric unlock, and DFX backend services has been retired — those gaps are closed.
+
+Out of scope of the gate and tracked elsewhere:
+
+- **Widget render paths** — measured separately via `testWidgets` specs, not in the line-coverage gate (deliberate; see `docs/testing.md` "Tier 0" rationale).
+- **Visual regression (goldens)** — every `lib/screens/**/*_page.dart` has a `test/goldens/**/*_golden_test.dart` companion, validated pixel-exact on the dfx01 self-hosted runner by the `Visual Regression` CI job. Not folded into the line-coverage gate. The one exception is `lib/screens/web_view/web_view_page.dart` — `InAppWebView` is a platform-view that has no headless render in `flutter_test`, the spec is committed with `skip: true`. See [`docs/visual-regression-tests.md`](docs/visual-regression-tests.md).
+- **Tier 2 (firmware simulator)** — runs in `bitbox-simulator.yml`, not folded into the scoped coverage number.
+- **Tier 3 (Maestro handbook flows)** — runs in `tier3-handbook.yaml`, not folded in.
+- **`lib/widgets/chain_asset_icon.dart`** and **`lib/widgets/image_picker_sheet.dart`** — `Image.asset` / `ImagePicker` platform-channel paths, see "Surface that needs infra work" in `docs/testing.md`.
+
+## Testing tiers
+
+[#314](https://github.com/DFXswiss/realunit-app/issues/314) defines a 5-tier model for BitBox-touching code:
+
+- **Tier 0 — Cubit unit tests** (`bloc_test` + `mocktail`). Fast, no platform, no BitBox. Covers every state transition.
+- **Tier 1 — FakeBitbox integration tests** (`FakeBitboxCredentials` at the BitBox boundary, runs under `flutter test --coverage`). Drives multi-layer flows without hardware. Specs live under `test/integration/`.
+- **Tier 2 — Firmware simulator** (TCP transport + Docker `bitbox02-firmware/simulator`). End-to-end with real crypto, no hardware. Planned.
+- **Tier 3 — Maestro flows** (`.maestro/handbook/*.yaml` for software-only flows; the BitBox02-hardware variant is deferred and has no flow files committed yet). The handbook flows run on a fresh iOS Simulator, automated via [`tier3-handbook.yaml`](.github/workflows/tier3-handbook.yaml) — opt-in on PRs via the `tier3:full` label, always runs on push to `develop`. An upstream Maestro driver-hang regression on `macos-latest` runners makes intermittent first-attempt failures expected; `scripts/run-handbook-flows.sh` retries the driver-hang class up to 3× per flow (CI-hardening work originally tracked in [#487](https://github.com/DFXswiss/realunit-app/issues/487), now closed). The hardware variant remains manually triggered before each release until Phase 3 of [#314](https://github.com/DFXswiss/realunit-app/issues/314) lands.
+- **Tier 4 — BLE VCR / replay** (capture on hardware once, replay deterministically). Stretch — most of its value is covered by Tier 2 + Tier 3 in tandem.
+
+Non-BitBox code only needs Tier 0 + widget tests; Tier 1+ are reserved for hardware-coupled paths.
+
+## Tests
+
+| Stack    | Command                   | What it covers                                                                                                                                                                                            |
+| -------- | ------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Flutter  | `flutter test`            | Unit + widget specs under `test/**` (pure-Dart `test` and `testWidgets`)                                                                                                                                  |
+| Coverage | `flutter test --coverage` | Writes `coverage/lcov.info`. CI narrows it to the activated surface and hard-fails when scoped coverage drops below the floor in `.coverage-floor-lines` / `.coverage-floor-functions`. See "Coverage infrastructure roadmap" above for the ratchet protocol. |
+| Analyzer | `flutter analyze`         | Dart static analysis per `analysis_options.yaml`                                                                                                                                                          |
+
+Tier 1 specs live under `test/integration/**` and run inside the same `flutter test --coverage` invocation as Tier 0 — no separate `integration_test/` harness today (that Flutter-convention directory is reserved for on-device runs that are not yet wired up). Tier 3 handbook flows (iOS Simulator) are wired via [`tier3-handbook.yaml`](.github/workflows/tier3-handbook.yaml); the BitBox02 hardware variant remains deferred.

+
+## Release versioning
+
+Tags follow plain SemVer: `vMAJOR.MINOR.PATCH`. There is no pre-release suffix — the previous `vX.Y.Z-beta.N` schema has been retired.
+
+| Component | When does it bump? | Workflow | Distribution |
+| --- | --- | --- | --- |
+| `PATCH` (`v1.0.X` with X >= 1) | Automatically on every push to `develop` (see `auto-tag.yaml`). | `release.yaml` (internal lane) | TestFlight + Play Internal. |
+| `MINOR` (`v1.X.0`) | Manual tag push (App-Store-update marker). | `release.yaml` (production-candidate lane) | TestFlight + Play Internal. Production promotion is done manually in the store backends. |
+| `MAJOR` (`vX.0.0`) | Manual tag push. | `release.yaml` (production-candidate lane) | TestFlight + Play Internal. Production promotion is done manually in the store backends. |
+
+A single release workflow (`release.yaml`) listens on the `v*` tag pattern and uses a guard job to route based on the PATCH component: patch tags go through the internal lane (`prerelease: true` on GitHub), MAJOR/MINOR tags through the production-candidate lane (`prerelease: false`). Either way the build lands in the Test tracks first — the App Store / Play Store production track is never updated by a tag push.
+
+Both `beta` lanes push the store **listing** (Fastlane metadata + screenshots) alongside the binary on every tag-driven release, so the listings stay in sync with the build. Android `supply` writes the (global) Play listing with the AAB. iOS `deliver` runs with `skip_app_version_update: false`, so it creates or selects the editable App Store version itself and stages the listing there — the Deliverfile's `submit_for_review false` + `automatic_release false` keep it staged for a human to submit; deliver never auto-submits or releases. The iOS `deliver` is **best-effort** (`deliver_best_effort` in `ios/fastlane/Fastfile`): until the app's first App Store version is created once in App Store Connect, Apple rejects creating it via the API ("cannot create a new version of the App in the current state"), so the push is logged loudly and skipped without failing the release (the TestFlight binary already shipped). After that one-time bootstrap, every release syncs the listing automatically. The same surface can also be synced without a binary via the `store_metadata` lane / `store-metadata.yaml`. Either way, `release.yaml` runs the same `scripts/check-store-metadata.sh` preflight (FIXME placeholders + character/URL limits) as `store-metadata.yaml` in a gating `store-metadata-preflight` job before either deploy lane runs — a tag can never ship a `FIXME-` placeholder or an oversize field to the live consoles. Production promotion / final submit stay manual.
+
+The build number is derived deterministically from the tag by `tool/generate_release_info.dart` using `MAJOR * 10_000_000 + MINOR * 100_000 + PATCH * 1_000 + 999`. The fixed `+999` suffix keeps every new build strictly above the legacy beta build codes; the first new build `v1.0.15` lands at `10_015_999`, comfortably above the highest published legacy beta `v1.0.0-beta.14` at `10_000_014`.

+`pubspec.yaml`'s `version:` field has two roles:
+
+- The `+0` build-number sentinel is for local builds — CI always overrides `--build-name` / `--build-number` from the tag. Don't bump the `+N` part manually.
+- The `X.Y.Z` part is a **floor** for MAJOR / MINOR jumps. Patch increments come from the latest tag; pubspec is only consulted to trigger jumps. To start a new MINOR / MAJOR train (e.g. `v1.1.0`), bump pubspec on `develop` and the next auto-tag will pick it up.
+
+Typical patch flow: PR merges into `staging` → `auto-staging-pr.yaml` opens the `staging → develop` PR → after that PR merges, `auto-tag.yaml` creates `v1.0.X` on `develop` → `release.yaml` (internal lane) ships the build to TestFlight + Play Internal.

+# API Authority Audit
+
+This document inventories every place in the realunit-app where business decisions
+are made locally instead of being delegated to the DFX API, as required by the
+*"API as Decision Authority"* rule in [`CONTRIBUTING.md`](../CONTRIBUTING.md).
+
+Findings were produced by four parallel scans (2026-05-21) over the KYC, Buy/Sell,
+Wallet/Service-layer, and Settings areas, then deduplicated and ranked by impact.
+
+Each item lists:
+- The violation ID (`V<N>`) used to cross-reference with [`api-authority-plan.md`](api-authority-plan.md)
+- The violation site (`file:line`)
+- The local decision being made
+- What an API-driven version should look like
+- Whether closing it requires an API change in [`DFXswiss/api`](https://github.com/DFXswiss/api)
+
+The `V<N>` anchors are stable: every finding in this audit carries one, and every
+wave entry in the plan cites the `V<N>` it closes. To answer *"which wave closes
+audit finding V12?"* search for `V12` in `api-authority-plan.md`.
+
+---
+
+## P0 — User-visible blockers caused by app-side gating
+
+These are the items where the app actively prevents a user from doing something
+the API would accept. Fixing these directly resolves real user complaints (e.g.
+the 2026-05-21 ident-misroute report that triggered this audit).
+
+### KYC routing decided in the cubit instead of by the API
+
+- **V1** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:16-22` — `_requiredStepNames` set
+  - **Local decision:** which step names count as "required for trading"
+  - **Backend already owns this** in `api/src/subdomains/generic/kyc/enums/kyc.enum.ts:requiredKycSteps(userData)` — the app duplicates a subset
+  - **API change needed:** add `isRequired: bool` to `KycStepDto`, drop the local set
+- **V2** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:24, 171` — `_minLevelForActions = 30` + `level < _requiredLevel` check
+  - **Local decision:** which numeric level unlocks trading
+  - **API change needed:** API returns `canTrade: bool` / `canPerformAction: bool` per user — the app renders, doesn't compute
+- **V3** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:142, 156-162` — `pendingStatuses` + `actionableStatuses` sets
+  - **Local decision:** which `ReviewStatus` values mean "user must act" vs "wait for review"
+  - **API change needed:** API's `KycInfoMapper.toDto` already picks `currentStep` — the app should render `currentStep` directly and stop iterating `kycSteps`
+- **V5** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:134-168` — manual filter + routing chain over `kycSteps`
+  - **Local decision:** entire next-step selection algorithm — duplicates `KycService.tryContinue` on the API
+  - **API change needed:** none — the `currentStep` field from `PUT /v2/kyc` already contains the answer; remove the loop, route from `currentStep` only
+  - **Closed by:** W2.2 (subsumed by the `_runCheckKyc` rewrite that collapses V1, V2, V3 — V5 is *the same loop* those three constants drive). Tagged separately so reviewers can grep the routing-chain code path explicitly.
+- **V45** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:_continueKyc` — `_continueKyc` repeats the same manual filter over `kycSteps`
+  - **Local decision:** `kycStatus.kycSteps.firstWhere((step) => step.isCurrent)` — parallel code path with the same anti-pattern as V5's `_runCheckKyc` loop, called after a realunit registration completes
+  - **API change needed:** none — the `currentStep` field is already authoritative; consume it directly. When W2.2 rewrites `_runCheckKyc` to render `currentStep` directly, this loop must also be deleted in the same PR
+  - **Closed by:** W2.2 (#494). `_continueKyc` now reads `KycSessionDto.currentStep` directly. A missing `currentStep` surfaces `KycUnsupportedStepFailure(null)` instead of throwing a bare `StateError` (which had been leaking as raw stack-trace text into the user-facing i18n message).
+- **V4** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:179-182` — `e.statusCode == 403 || e.code == 'TFA_REQUIRED'` → emit 2FA step
+  - **Local decision:** translate HTTP status into a UI flow
+  - **API change needed:** API returns `nextStep: '2fa'` in the response body — app does not switch on status codes
+- **V20** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:88-104` — auto-register email when `level < 10`
+  - **Local decision:** infer that level<10 means "the email step is implicit, call the registration endpoint silently"
+  - **API change needed:** if auto-registration is desired the API performs it server-side; the app calls `continueKyc` and renders what comes back
+
+### Hardcoded transaction limits
+
+- **V7** — `lib/screens/buy/cubits/buy_payment_info/buy_payment_info_cubit.dart:16, 50-60` — `_minAmountChf = 100` pre-flight
+  - **API change needed:** `POST /v1/buy/quote` already validates min/max — return `minAmount` / `maxAmount` / `error` from the API, surface its error verbatim
+- **V8** — `lib/screens/sell/cubits/sell_payment_info/sell_payment_info_cubit.dart:17, 82-112` — `_minAmountChf = 10` + `validateMinAmount()` pre-flight
+  - **API change needed:** same shape on `POST /v1/sell/quote` — remove the local validate method entirely
+
+### Hardcoded routing forks based on wallet type
+
+- **V16** — `lib/screens/sell/widgets/sell_button.dart:60-62` — `if (state.isBitbox) → AppRoutes.sellBitbox`
+  - **Local decision:** which sell-flow page to use based on hardware-wallet presence
+  - **API change needed:** API returns `requiredWorkflow: 'sell' | 'sellBitbox'` (or a list of steps) — app dispatches on that string
+
+### Feature visibility decided by local heuristics
+
+- **V6a** — `lib/screens/settings_user_data/settings_user_data_page.dart:239` — Edit button hidden if `statusLabel != null` (i.e. `inReview`)
+  - **API change needed:** API returns `editable: bool` per field; app does not introspect status to compute editability
+- **V6b** — `lib/screens/settings_user_data/subpages/edit_name/cubit/settings_edit_name_cubit.dart:22` — `if (session.currentStep?.status == KycStepStatus.inReview)` blocks editing
+  - Same as V6a — render an API capability flag, do not switch on status
+- **V6c** — `lib/screens/settings_user_data/subpages/edit_address/cubit/settings_edit_address_cubit.dart:22` — same `if (session.currentStep?.status == KycStepStatus.inReview)` interpretation as V6b
+  - Identical shape, separate cubit. Both must be migrated together in W3.2 — listed separately so the grep target is unambiguous.
+- **V6d** — `lib/screens/settings_user_data/cubit/settings_user_data_cubit.dart:18-22` — `_changeStepNames` static const set ({nameChange, addressChange, phoneChange})
+  - **Local decision:** which KYC step names represent a user-data change flow — same shape as `_requiredStepNames` (V1), just a different subset
+  - **API change needed:** API exposes a `category: 'changeRequest'` (or similar) flag on `KycStepDto`, app filters by it
+- **V9** — `lib/screens/settings_contact/settings_contact_page.dart:54-67` (the page reads `emailSet`) + `lib/screens/settings_contact/cubit/settings_contact_cubit.dart:22` (the cubit computes `emailSet: userDto.mail != null` from the user DTO) — "Contact Support" only shown if email is set
+  - **API change needed:** API exposes `support.available: bool` (or always allow it through the support endpoint and the API returns 400 if not eligible)
+  - **Closed by:** [api#3772](https://github.com/DFXswiss/api/pull/3772) (`createSupportTicket: { available, missingPrerequisite? }` on `UserCapabilitiesDto`) + companion app PR. Path was non-linear — see the Wave-3 lessons-learned in [`api-authority-plan.md`](api-authority-plan.md#lessons-learned--wave-3-reset-2026-05-26) for the six-PR history that landed the final shape.
+- **V13b** — `lib/screens/settings/settings_page.dart:100` — "Wallet Backup" only shown if `walletType == WalletType.software`
+  - **Boundary case:** wallet-type is a device-local fact (BitBox cannot expose its seed); this one is **defensible** as a UI capability. **Accepted as documented exception** (see *Documented exceptions* in `api-authority-plan.md`). Tagged for completeness.
+
+---
+
+## P1 — Local interpretation of API state
+
+These do not block users today, but every one accumulates drift between the
+backend's understanding of state and the app's interpretation of it.
+
+### Hardcoded language sent to backend on registration
+
+- **V41** — `lib/packages/service/dfx/real_unit_registration_service.dart:117` — `lang: 'DE'` constant sent to the API on registration completion
+  - **Local decision:** account language is hardcoded to `'DE'` regardless of the user's actual settings-language / device locale — silently miscategorizes the user's UI language
+  - **API change needed:** API derives account language from `Accept-Language` header (or settings-language) on the request; or — interim — the app sends the user's actual settings-language. The app must not pick a fixed value
+  - **Closed by:** W4.4 (extended) — handled together with the recommended-language work in W4.3 / W4.4
+
+### Client-side mapping of KYC financial-question key to UI action
+
+- **V43** — `lib/screens/kyc/steps/financial_data/subpages/kyc_financial_data_questions_page.dart:110-122` — switch on `question.key == 'tnc'` / `'notification_of_changes'` to pick action target
+  - **Local decision:** which `key` opens a webview (with a hardcoded URL) vs which routes to Support — encoded in the rendering page; any new question type added server-side silently fails to surface the right action
+  - **API change needed:** extend `KycFinancialQuestion` DTO with a structured `link: { url?: string, action?: 'support' \| 'webview' }` (or equivalent). The page renders the link metadata; it does not switch on `key` literals
+  - **Closed by:** W3.1 / W3.2
+
+### Local session gates that should be positioned by the API
+
+- **V21** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:31, 113-115` — `_legalDisclaimerAccepted`
+  - The flag itself is a legitimate per-session security gate. **The violation is its position in routing** — the app inserts disclaimer between email and registration unilaterally. **API change needed:** API returns `currentStep: 'legalDisclaimer'` when it wants the disclaimer to show.
+- **V22** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:40, 117-119` — `_registrationSignProduced`
+  - Same shape — per-session sign-gate is fine; deciding *when* to surface the registration page from the cubit is not. **API drives the position.**
+
+### JWT decoded locally to detect merge
+
+- **V23** — `lib/screens/kyc/steps/email/cubits/email_verification/kyc_email_verification_cubit.dart:49-63` — parses JWT, extracts `account` claim, compares before/after to detect merge
+  - **API change needed:** `POST /v1/realunit/register/wallet` (or a new `/kyc/check-merge`) returns `{ merged: true, mergedAccountId }` directly — the app does not introspect tokens
+
+### Transaction state interpretation in the UI
+
+- **V24** — `lib/screens/dashboard/widgets/pending_transaction_row.dart:49-51` — `if (transaction.state == .waitingForPayment)` switches label
+  - **API change needed:** API returns `statusLabel` / `statusKey` as a string the app can render or translate; app does not switch on enums
+
+### Status code semantics
+
+- **V25** — `lib/packages/service/dfx/dfx_auth_service.dart:233-239` — `401 → refresh token`
+  - HTTP-standard behavior, but still a local interpretation. **Accepted as documented exception** (see *Documented exceptions* in `api-authority-plan.md`); 401-on-this-endpoint contractually means "JWT expired". Tagged for completeness.
+
+### Polling/retry orchestration with local generation tokens
+
+- **V26** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:42-69` — `_runGeneration` cancellation token + 30s timeout
+- **V27** — `lib/screens/kyc/steps/email/cubits/email_verification/kyc_email_verification_cubit.dart:24-37` — `_mergeDetected` + generation tracking, multi-step propagation race handling
+  - **Local decision:** when to give up, how to retry, what counts as a recoverable failure
+  - **API change needed:** API exposes a single idempotent `/check-merge` endpoint that handles propagation internally — app stops orchestrating
+
+### Registration-submit treats backend rejection as success
+
+- **V15** — `lib/screens/kyc/steps/registration/cubits/registration_submit/kyc_registration_submit_cubit.dart:76, 92` — on `"already registered"` API error, emit `Success` to let `KycCubit` resolve the next state
+  - **Local decision:** that an API "no" is actually "yes, with a different next step"
+  - **API change needed:** API returns `{ status: 'already_registered', nextStep: 'merge' }` and the app dispatches; the cubit must not paper over a 400
+
+### Local startup gate that delays API surface
+
+- **V34** — `lib/main.dart:120` — `if (!homeState.softwareTermsAccepted) ...` blocks the dashboard until terms acceptance
+  - **Local decision:** that the user cannot reach any *API-allowed* screen until a UI-local preference is set
+  - **API change needed:** none — the gate itself is acceptable as a one-time UX overlay, but its *position* (between boot and any API-driven flow) violates the rendering-layer rule. Move to a one-time Dashboard overlay so the API gets to drive routing first
+
+---
+
+## P2 — Hardcoded lists / config that should come from the API
+
+### Currency, language, country, network
+
+- **V12** — `lib/styles/currency.dart:3-22` — `enum Currency { EUR, CHF }`
+  - **API change needed:** call `/v1/fiat` and render the list returned for this user's region
+- **V46** — `lib/screens/kyc/steps/registration/steps/kyc_registration_personal_step.dart:50-53` — `[RegistrationUserType.values.first]` restricts the account-type dropdown to a single value
+  - **Local decision:** the DTO carries multiple `RegistrationUserType` values but the UI only renders `.values.first` (i.e. `human`). Which account types this branded app exposes is a business decision frozen in code
+  - **API change needed:** `availableUserTypes: ['human']` capability flag on `UserV2Dto` (or on the registration endpoint response); app renders the returned list. Same shape as V12 / V13
+  - **Deferred:** not in W3.1 / W3.2 scope — the dropdown source is `RegistrationUserType.values` (a local enum), not a capability list from `UserCapabilitiesDto`. Surfacing the available account types requires a separate API change (own capability field or endpoint extension) and a UI migration; tracked for a follow-up wave.
+- **V13** — `lib/styles/language.dart:3-22` — `enum Language { EN, DE }`
+  - **API change needed:** call `/v1/language` (already exists on the DFX API)
+- **V14** — `lib/widgets/form/country_field.dart:65-79` — `['CH', 'DE', 'IT', 'FR']` priority list at top
+  - **API change needed:** `/v1/country?priority=true` returns ordered list; UI does not hardcode preference
+- **V28** — `lib/packages/config/network_mode.dart:4-20` — `enum NetworkMode { mainnet, testnet }`
+  - **Boundary case:** network mode determines *which* API host the app calls. Cannot itself be API-driven (chicken-and-egg). **Accepted as documented exception** (see `api-authority-plan.md`). Tagged for completeness.
+
+### Currency / language dropdowns rendered from local enum
+
+- **V10a** — `lib/screens/buy/widgets/payment_converter.dart:83` — `Currency.values.map()`
+- **V10b** — `lib/screens/sell/widgets/sell_converter.dart:201` — `Currency.values.map()`
+- **V10c** — `lib/screens/settings_currencies/settings_currencies_page.dart:26` — `Currency.values.map()` (settings currency picker)
+- **V13c** — `lib/screens/settings_languages/settings_languages_page.dart:24` — `Language.values.map()` (settings language picker)
+  - All four are the same root cause as V12 / V13 — fix the source enum and these surfaces switch to the API list automatically. Closed together by W1.3 (currencies) / W1.4 (languages).
+
+### Legal documents URLs hardcoded
+
+- **V17** — `lib/packages/config/legal_documents_config.dart:69-122, :160-191, :193-236` — Registration-Agreement PDFs (DE/EN), RealUnit Prospekt URLs (`:69-122`), Aktionariat document URLs (`:160-191`), DFX-Docs URLs (`:193-236`)
+  - **API change needed:** `/v1/legal-document?type=registration&language=de` returns the current URL + version; app renders without knowing URLs in advance. Same endpoint also covers the Aktionariat and DFX-Docs blocks
+- **V44** — `lib/screens/kyc/steps/financial_data/constants/kyc_financial_data_links.dart:2` — hardcoded `https://dfx.swiss/terms-and-conditions`
+  - **Local decision:** same root cause as V17 but outside `legal_documents_config.dart` — a separate constants file holds a legal URL
+  - **API change needed:** `/v1/legal-document` endpoint (the same endpoint W4.1 introduces); app reads the URL instead of compiling it in
+  - **Closed by:** W4.4 (same wave as V17)
+
+### Company contact info hardcoded
+
+- **V18** — `lib/screens/settings_contact/settings_contact_page.dart:82, 93-94, 104, 109, 133-134` — phone, email, website, postal address
+  - **API change needed:** `/v1/company-info` (or the existing `/v1/settings`) returns this for the RealUnit branding; allows future white-labeling
+
+### Asset configuration hardcoded
+
+- **V29** — `lib/packages/config/api_config.dart:19-22` — RealUnit token address, chainId, decimals (mainnet + Sepolia variants)
+  - **API change needed:** `/v1/asset?app=realunit` returns the canonical token configuration; the app reads + caches per network mode
+- **V30** — `lib/packages/utils/default_assets.dart:3-22` — ETH/ZCHF asset IDs per network
+  - **Boundary case:** the app *is* the RealUnit wallet, by definition it knows which token it manages. **Out of scope** for the current waves — listed for completeness but explicitly accepted as a boundary case (see Wave 5 rationale in `api-authority-plan.md`). Asset IDs from `/v1/asset` would be cleaner but this is the lowest-priority offender — defer until a multi-asset wallet need surfaces.
+
+### Date / size constants
+
+- **V31** — `lib/screens/transaction_history/transaction_history_page.dart:68-69, :82` — `firstDate: DateTime(2025)` on the start-date picker (`:68-69`) **and** the end-date picker (`:82`)
+- **V32** — `lib/screens/settings_tax_report/settings_tax_report_page.dart:73` — `firstDate: DateTime(2025)` on tax-report picker
+  - **API change needed:** `/v1/user/account-bounds` returns `{ firstTransactionDate, lastTransactionDate }`; both pickers use that as `firstDate`
+- **V33** — `lib/screens/settings_seed/settings_seed_view.dart:98` — `if (wordCount != 12)` mnemonic length check
+  - **Local concern — local crypto invariant.** BIP-39 length is structural, not a business rule. **Accepted as documented exception.** Tagged for completeness.
+
+### Default language selection
+
+- **V19** — `lib/packages/repository/settings_repository.dart:18-24` — `systemLang == 'de' ? 'de' : 'en'`
+  - **API change needed:** API recommends a default language per user/region; until then, this is acceptable Frontend-only behavior (no user has been onboarded yet).
+
+### Default currency selection
+
+- **V42** — `lib/packages/repository/settings_repository.dart:28` — `_sharedPreferences.getString('currency') ?? 'CHF'`
+  - **Local decision:** the fallback currency, used when the user has never picked one, is hardcoded to CHF. Same shape as V19's language fallback, just for currency
+  - **API change needed:** API recommends a default currency per user/region (alongside the recommended language from W4.3); app uses it as the fallback. Same wave as V19
+  - **Closed by:** W4.4 (extended) — alongside the recommended-language work
+
+### Tax-report date transformation chosen client-side
+
+- **V47** — `lib/screens/settings_tax_report/cubit/settings_tax_report_cubit.dart:53-64` — `_getDateWithLatestTime(selectedDate)` decides whether to ask the API for "now minus 1 minute" (today) or "end of day" (past dates)
+  - **Local decision:** which exact UTC timestamp the API should evaluate the balance at, derived locally from "is the selected date today"
+  - **API change needed:** `/v1/realunit/balance/pdf` accepts a date (not a timestamp) and the server picks the appropriate evaluation moment. The app sends `date` only; backend owns the time semantics. UX-only — not user-blocking
+  - **Closed by:** W5.1 (extended)
+
+### Faucet-vs-ready decision derived from raw API balances
+
+- **V48** — `lib/screens/sell_bitbox/cubit/sell_bitbox_cubit.dart:51, :81` — `if (_paymentInfo.ethBalance >= _paymentInfo.requiredGasEth) … else _requestFaucet()` (and the same comparison in the 5s polling loop at `:81`)
+  - **Local decision:** the client compares two API-supplied numbers to decide "request faucet" vs "ready". A semantic decision encoded as a numeric inequality
+  - **API change needed:** `SellPaymentInfoDto` (or the sell endpoint response) exposes `needsFaucet: bool` and optionally `faucetPollingHint: int` (seconds). App renders the boolean and the hinted polling interval instead of computing them
+  - **Closed by:** W5 (new sub-item)
+
+### Support categories + labels hardcoded
+
+- **V49** — `lib/screens/support/subpages/support_create_ticket_page.dart:85-110` (UI list of `SupportIssueType` tiles) + `lib/screens/support/cubits/support_create_ticket/support_create_ticket_cubit.dart:48-57` (non-i18n English labels in `_getTicketName`)
+  - **Local decision:** which support categories this branded app exposes — a business decision baked into the page — and the human-readable label of each category, in English only, baked into the cubit
+  - **API change needed:** `/v1/support/issue-types` capability endpoint returning `{ key, icon, label }[]`. App renders the list with localized labels from the API (or i18n keys keyed on `key`). Adding a new category requires no app release
+  - **Closed by:** W4 (or a new endpoint slot in W4) — additive
+
+---
+
+## P3 — DTO/enum mirroring (acceptable boilerplate, but watch for drift)
+
+These are not violations of the rule (DTOs *must* mirror the API for type safety),
+but they're listed so reviewers know what to keep in sync when the API changes.
+
+- **V35** — `lib/packages/service/dfx/models/kyc/kyc_level.dart` — `KycLevel`, `KycStepName`, `KycStepStatus`, `KycStepType`, `KycStepReason` enums with `fromValue` / `toValue`
+- **V36** — `lib/packages/service/dfx/models/registration/registration_status.dart`
+- **V37** — `lib/packages/service/dfx/models/registration/registration_email_status.dart`
+- **V38** — `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:224-231` — `_mapStepName()` switch from `KycStepName` to UI `KycStep`
+
+The `KycStepName → KycStep` map is borderline: it's a UI-routing decision (which
+page to show per backend step). If `KycStepDto` carried a `uiHint: 'identPage'`
+field, the app would not need this map at all. **API change suggested but not
+required.**
+
+---
+
+## P4 — Already addressed / documented elsewhere
+
+For completeness:
+
+- **V11** — `lib/screens/sell/widgets/sell_bank_account_field.dart` + `lib/screens/sell/widgets/sell_bank_account_selection_page.dart` — auto-selection now consumes `BankAccountDto.default` (mapped through to `BankAccount.isDefault`) under a strict `isDefault && isActive` filter on both surfaces; no positional fallback. Multi-default ambiguity is logged via `developer.log` and resolved by picking the first list entry. **Closed by:** W1.2 / [`DFXswiss/realunit-app#495`](https://github.com/DFXswiss/realunit-app/pull/495).
+- **V39** — `lib/screens/kyc/steps/email/kyc_email_page.dart:91` — `markRegistrationSignProduced()` after merge confirmation. Local session-gate position, called from a code path where the API already signaled success. Fixed by [`DFXswiss/realunit-app#466`](https://github.com/DFXswiss/realunit-app/pull/466). **OK.**
+- **V40** — `KycEmailVerificationCubit._completeRegistration` — surfaces failures correctly ([`DFXswiss/realunit-app#466`](https://github.com/DFXswiss/realunit-app/pull/466) / [`DFXswiss/api#3731`](https://github.com/DFXswiss/api/pull/3731)). Once [`DFXswiss/api#3731`](https://github.com/DFXswiss/api/pull/3731) merges and the `register/wallet` endpoint is idempotent, the client-side retry logic at the email verification page can be simplified further.

+## Summary
+
+Numbers below are the **canonical counts** used everywhere this audit is referenced (plan, PR body, future PRs). Recounted from this file on 2026-05-21.
+
+| Severity | Count | V-IDs | Primary location |
+|---|---|---|---|
+| **P0** — blocks users today | 16 | V1–V5, V6a–V6d, V7, V8, V9, V13b, V16, V20, V45 | `kyc_cubit.dart` (7 incl. `_continueKyc`), buy/sell payment-info cubits (2), settings user-data + edit cubits (4), settings_contact (1), settings (1), sell_button (1) |
+| **P1** — local interpretation, no immediate block | 11 | V15, V21–V27, V34, V41, V43 | `kyc_cubit.dart` + email-verification + registration-submit cubits + main.dart + real_unit_registration_service + financial-data questions page |
+| **P2** — hardcoded lists/config | 22 | V10a–V10c, V12, V13, V13c, V14, V17–V19, V28–V33, V42, V44, V46, V47, V48, V49 | currency/language/country, legal docs, company info, assets, date pickers, default currency, tax-report date, faucet decision, support categories, registration user types |
+| **P3** — DTO mirroring (informational) | 4 | V35–V38 | service/dfx/models |
+| **P4** — fixed or in-flight | 3 | V11, V39, V40 | tracked in [`DFXswiss/realunit-app#466`](https://github.com/DFXswiss/realunit-app/pull/466) / [`DFXswiss/realunit-app#495`](https://github.com/DFXswiss/realunit-app/pull/495) / [`DFXswiss/api#3731`](https://github.com/DFXswiss/api/pull/3731) |
+
+**Total distinct violations across P0–P2:** 49 (16 + 11 + 22). Recounted on 2026-05-21 after a post-initial-review audit pass found 9 additional violations (V41–V49) that the initial four-stream scan had missed; V11 moved to P4 once W1.2 shipped.
+**Plus boundary cases accepted as documented exceptions:** V13b, V25, V28, V30, V33 — tagged in the audit, not counted as actionable.
+**Actionable P0–P2 (excluding documented exceptions):** 44.
+
+**Most-affected single file:** `lib/screens/kyc/cubits/kyc/kyc_cubit.dart` —
+~10 distinct violations. The entire `_runCheckKyc` body should be replaceable by
+"render `currentStep` from the API, that's it" once the matching API fields land.
+
+## How to use this list
+
+- **For new PRs:** check whether your change touches any line in this file. If yes,
+  prefer to *remove* a violation (P0 → P3 in that order) rather than add one.
+- **For backend PRs:** every P0/P1 item has a paired API field that's missing.
+  When you extend the API to deliver that field, the app PR that consumes it
+  should also delete the corresponding local logic in the same PR.
+- **For the architecture review on 2026-05-21:** the P0 list is the actionable
+  short-list. P2 is a longer-term cleanup. P3/P4 are acknowledged exceptions.
+
+---
+
+## Shipped (2026-05-21)
+
+Pair-PRs landed against the rule, in dependency order:
+
+| Wave | API PR | App PR | Closes V-IDs |

+
+PRs #491 and #492 are already merged. The remaining 9 are Draft per DFXswiss convention. Every PR has full test coverage; `flutter test` and `npm test` clean across all branches. The W2 pair specifically closes the 2026-05-21 incident report (user_data 338759 ident-misroute).
+
+## Outstanding — next phase
+
+Items not shipped in the 2026-05-21 batch, in priority order:
+
+**P0 remainders:**
+- V6c (settings_edit_address_cubit) — same shape as V6b; landed in W3.2 as part of the broader capability migration.
+- V6d (`_changeStepNames` static set) — small follow-up to W3.2; the page already reads `capabilities` for the gating decision, the set just hangs around in the cubit for the `pendingSteps` informational badge.
+- V16 (sell_button isBitbox routing) — re-evaluated: BitBox vs software-wallet is a device-local fact the API cannot substitute for. Treat as documented exception unless a future `supportedSignMethods` API field changes the picture.
+- V20 (auto-register email at level<10) — the cubit still owns this branch; backend-side auto-registration would close it. Spec'd for Wave 5.
+
+**Wave 4 follow-ups (post-merge):**
+- V19 (recommended language per region) — not part of W4's initial scope; spec'd for a follow-up alongside V20.
+- WebDocumentConfig hardcodes (5 entries in `legal_documents_config.dart`: EU prospectus pages, CH stock-exchange prospectus, articles of association, investment regulations) — these point at marketing-managed download pages, not versioned PDFs; documented exception.
+
+**P1 / P2 long tail:**
+- V21, V22 — local session gates whose *position* should be API-driven (separate follow-up after W4).
+- V23–V27 — JWT introspection, polling/retry orchestration, transaction state interpretation. Several depend on new API fields not yet scoped.
+- V29–V33 — hardcoded asset config, date constants, default language. Tracked but not blocking.

+# API Authority — Implementation Plan
+
+Sequenced, pair-PR plan to enforce the *"API as Decision Authority"* rule
+defined in [`CONTRIBUTING.md`](../CONTRIBUTING.md). Companion to the violation
+inventory in [`api-authority-audit.md`](api-authority-audit.md).
+
+**Source of truth:** the DFX API (`DFXswiss/api`, branch `develop`).
+**Consumer:** this app (`DFXswiss/realunit-app`, branch `develop`).
+**Author:** generated from a 4-stream subagent scan + 3-stream API-side gap analysis (2026-05-21). All file:line citations were verified against the cloned repos.
+

+
+## Executive summary
+
+All counts below are the **canonical numbers** for this PR; the audit file lists every V-ID. Numbers are derived from a single recount of `api-authority-audit.md` on 2026-05-21.
+
+| | Count | Notes |
+|---|---|---|
+| Distinct violations in audit (P0–P2 bulleted) | 50 | 16 P0 + 12 P1 + 22 P2 (post-initial-review pass added V41–V49) |
+| Of those, **documented exceptions** (rule does not apply) | 5 | V13b (BitBox backup), V25 (401 refresh), V28 (network mode), V30 (default assets), V33 (BIP-39) |
+| **Actionable** P0–P2 (recounted from audit) | 45 | what the waves below close |
+| Closed by Wave 1 (app-only, ships today) | 11 across 6 items | V4, V7, V8, V10a, V10b, V10c, V11, V12, V13, V13c, V34 |
+| Closed by Wave 2 (KYC routing collapse) | 7 | V1, V2, V3, V5, V21, V22, V45 (session-gate positions move under the API; V45 is the parallel `_continueKyc` loop) |
+| Closed by Wave 3 (capability flags) | 9 | V6a, V6b, V6c, V6d, V9, V15, V16, V43, V46 |
+| Closed by Wave 4 (new endpoints) | 8 | V14, V17, V18, V19, V41, V42, V44, V49 |
+| Closed by Wave 5 (remaining P1/P2) | 10 | V20, V23, V24, V26, V27, V29, V31, V32, V47, V48 |
+| P3 (DTO mirroring, informational) | 4 | V35–V38, not counted as actionable |
+| P4 (already addressed) | 2 | V39, V40 |
+
+**Effort estimate:** 5 sequenced waves over ~7 sprints (14 weeks at 1 dev), or 4-5 weeks if 2 devs work in parallel (one API, one App).
+
+**Risk envelope:** all API changes are additive (new optional fields, new optional status values, new endpoints). No breaking changes — the audit is closed by *enriching* the API, not by *changing* it. Old clients continue to work.
+
+---
+
+## Operating principles
+
+These principles govern every PR generated from this plan. Violating them undoes the audit.
+
+### 1. Pair-PR convention
+
+For each violation that requires an API change:
+
+- **API PR** lands first on `develop` (DFXswiss/api): adds the field/endpoint, fully tested, additive only.
+- **App PR** opens within 1 week of API PR merge: consumes the new field and **deletes the corresponding local logic in the same PR**.
+- The app PR title references the API PR (`Closes DFXswiss/api#NNNN`).
+
+An API field that ships without a consuming app PR within 4 weeks is a regression — track in [`api-authority-audit.md`](api-authority-audit.md) and address in the next sprint.
+
+### 2. Additive-only API changes
+
+- New fields: `@ApiPropertyOptional`, `nullable: true` in TypeScript, default to safe value in mapper.
+- New enum values: append to existing enums, never reorder or remove.
+- New endpoints: live alongside old ones; deprecate old endpoints only in a separate later PR.
+- DB migrations: see `api/CONTRIBUTING.md:16` (preferred TypeORM-generated, fallback hand-written; immutable once on develop).
+
+### 3. Delete local logic in the same PR
+
+When the app PR consumes a new API field, it **must** delete the local business logic it replaces. Half-migrations (both local and API logic running) are explicitly forbidden — they become permanent.
+
+### 4. Stop adding new violations
+
+PR reviews must check this list. Any new `if`/`switch`/`.filter()` over status / level / capability data needs justification. The lint pass on `CONTRIBUTING.md`'s test rule ("Wer entscheidet?") applies to all new code.
+
+---
+
+## Wave 1 — Quick wins (app-only, ships immediately)
+
+**6 items closing 11 audit findings**, all unblocked **today** — the API already returns what's needed. The app just isn't using it. Smallest, lowest-risk wins; ship first to build confidence in the rule.
+
+### W1.1 — Buy/Sell min-amount validation comes from quote
+
+| | |
+|---|---|
+| Closes | V7, V8 |
+| API change | none — `BuyQuoteDto.minVolume`, `SellQuoteDto.minVolume` already exist (verified: `api/src/subdomains/core/buy-crypto/.../buy-quote.dto.ts:29-39`, `api/src/.../sell-quote.dto.ts:29-39`) |
+| App change | Remove `_minAmountChf` constants and `validateMinAmount()`; submit any amount; render error from API |
+| Files touched | `lib/screens/buy/cubits/buy_payment_info/buy_payment_info_cubit.dart` (delete lines 16, 50-60) `lib/screens/sell/cubits/sell_payment_info/sell_payment_info_cubit.dart` (delete lines 17, 82-112) `lib/screens/sell/widgets/sell_button.dart` (drop `SellPaymentInfoMinAmountNotMet` state if dependent) |
+| Acceptance | App sends amount=1 CHF → API returns 400 with `errors: [{ error: 'AMOUNT_TOO_LOW', limit: minVolume }]` → snackbar renders that error verbatim |
+| Test plan | Widget test: submit amount=1, mock API 400 with `limit: 100`, assert snackbar shows "100" |
+| Risk | Low — error is already structured, only the source of the limit changes |
+| Effort | XS (~2h) |
+
+### W1.2 — Bank-account default selection
+
+| | |
+|---|---|
+| Closes | V11 |
+| API change | none — `BankAccountDto.default: boolean` already exists (verified: `api/src/.../bank-account.dto.ts:17-22`) AND the app's own `BankAccountDto` already exposes it as `isDefault` (verified: `lib/packages/service/dfx/models/bank_account/dto/bank_account_dto.dart:6, 22`). No parsing work needed. |
+| App change | `sell_bank_account_field.dart:41-44` → `state.accounts.firstWhereOrNull((a) => a.isDefault)` instead of `.lastWhereOrNull((a) => a.isActive)`. One-line change. |
+| Acceptance | App auto-selects the account flagged `default: true` by the API. If multiple defaults (shouldn't happen) → first wins. If no default → no auto-selection. |
+| Test plan | Unit test on the field selection logic with three account shapes (one default, no default, multiple defaults) |
+| Risk | Low |
+| Effort | XS (~30 min) |
+
+### W1.3 — Currency list from `/v1/fiat`
+
+| | |
+|---|---|
+| Closes | V12 (enum source) + V10a, V10b, V10c (all three `Currency.values` renderers) |
+| API change | none for basic list — `GET /v1/fiat` returns `FiatDetailDto[]` with `buyable/sellable` flags (verified: `api/src/shared/models/fiat/fiat.controller.ts:10-34`) |
+| App change | Delete `lib/styles/currency.dart` enum. Replace `Currency.values` calls in `payment_converter.dart:83`, `sell_converter.dart:201`, and `settings_currencies_page.dart:26` with a `FiatRepository` that caches the API response. Filter by `buyable: true` for buy converter, `sellable: true` for sell converter; full list for settings picker. |
+| Acceptance | New fiats added in the backend appear in the converter without an app release |
+| Test plan | Widget tests with mocked `/v1/fiat` response containing CHF, EUR, USD — verify all appear in dropdown |
+| Risk | Low — fallback to local enum if `/v1/fiat` fails (degrade gracefully on first launch with no network) |
+| Effort | S (~half day) |
+
+### W1.4 — Language list from `/v1/language`
+
+| | |
+|---|---|
+| Closes | V13 (enum source) + V13c (settings_languages_page renderer) |
+| API change | none — `GET /v1/language` returns `LanguageDto[]` (verified: `api/src/shared/models/language/language.controller.ts:8-17`) |
+| App change | Replace `lib/styles/language.dart` enum with API-driven list. `settings_languages_page.dart:24` reads from API instead of `Language.values`. |
+| Acceptance | New language enabled server-side appears in app within one API refresh cycle |
+| Test plan | Same pattern as W1.3 |
+| Risk | Low |
+| Effort | S |
+
+### W1.5 — Render `TFA_REQUIRED` from response body, not status code
+
+| | |
+|---|---|
+| Closes | V4 (clean it up — works today, but app reads status code) |
+| API change | none — `TfaRequiredException` already returns `{code: 'TFA_REQUIRED', level, message}` in body (verified: `api/src/.../tfa-required.exception.ts`) |
+| App change | `kyc_cubit.dart:179-182` → match on `e.code == 'TFA_REQUIRED'` only; remove the `statusCode == 403` part. Long-term the API should also expose this via a body field on the regular `GET /v2/kyc` so the exception path is unnecessary, but that's Wave 3 |
+| Acceptance | App routes to 2FA step on body code, regardless of HTTP status |
+| Risk | Low |
+| Effort | XS |
+
+### W1.6 — `softwareTermsAccepted` gate moves off the boot path
+
+| | |
+|---|---|
+| Closes | V34 |
+| API change | none — local UI state, but the gate must not block the user from reaching any *API-allowed* state |
+| App change | `lib/main.dart:120` → drop the `if (!homeState.softwareTermsAccepted)` boot-time gate. Show terms as a one-time overlay on Dashboard if not accepted. App-startup is never gated by terms. |
+| Acceptance | First-run user with terms unaccepted lands on Dashboard with the overlay; API-driven KYC routing fires before any local UI gate |
+| Risk | Low |
+| Effort | S |
+
+**Wave 1 total effort:** ~1.5–2 dev-days. Closes 11 audit findings across 6 items with zero backend dependency.
+
+---
+
+## Wave 2 — KYC routing collapse (one API PR unlocks the central misroute)
+
+This is the single highest-impact wave. **One API PR + one App PR** rewrites the core of `kyc_cubit.dart` and closes the 2026-05-21 ident-misroute that started this audit.
+
+### W2.1 (API PR) — KYC step + level capabilities
+
+| | |
+|---|---|
+| Closes | V1, V2, V3, V5 (foundation for Wave 2 app work — `currentStep` already exists; V5 needs no field, just the cubit rewrite that V1/V2/V3 enable) |
+| Repo | DFXswiss/api, branch `feat/kyc-decision-fields` |
+| Changes | 1. `KycStepDto` (`src/subdomains/generic/kyc/dto/output/kyc-info.dto.ts:60-63`): add `@ApiProperty() isRequired: boolean`  2. `UserKycDto` (`src/subdomains/generic/user/models/user/dto/user-v2.dto.ts:116-134`): add `@ApiProperty() canTrade: boolean` (computed: `kycLevel >= LEVEL_30 && all required steps Completed && no Outdated/InProgress on Ident/FinancialData`)  3. `KycLevelDto`: add `@ApiProperty({enum: KycProcessStatus}) processStatus: KycProcessStatus` where `KycProcessStatus = 'InProgress' \| 'PendingReview' \| 'Completed' \| 'Failed'`  4. `KycStepMapper.toStep` + `KycInfoMapper.toDto` populate the new fields |
+| Acceptance | `GET /v2/kyc` response: every step has `isRequired`; top-level has `processStatus`. `GET /v2/user` response: `kyc.canTrade` is correctly computed for the level-50-with-outdated-ident edge case |
+| Test plan | New tests in `kyc-info.mapper.spec.ts`: user_data 338759 fixture (level 53, ident outdated, ident-seq-1 in-progress) → `canTrade: false`, `processStatus: InProgress`. Level-50-clean fixture → `canTrade: true`, `processStatus: Completed` |
+| Risk | Low (additive). Care: `canTrade` semantics must match the existing implicit rule in the *app today* exactly, otherwise the migration changes behavior for users in the wild |
+| Effort | M (~1 day) |
+
+### W2.2 (App PR) — Render `currentStep` from API, delete the cubit's business logic
+
+| | |
+|---|---|
+| Closes | V1, V2, V3, V5, V21, V22, V45, original 2026-05-21 ident-misroute report |
+| Repo | DFXswiss/realunit-app, branch `refactor/kyc-cubit-api-driven` |
+| Changes | Rewrite `lib/screens/kyc/cubits/kyc/kyc_cubit.dart:_runCheckKyc`. Specifically: 1. Delete `_requiredStepNames` (line 16-22) and `_minLevelForActions` (line 24)  2. Delete `actionableStatuses`, `pendingStatuses`, the iteration at lines 134-168  3. Read `processStatus` and `canTrade` from API response  4. Route purely from `currentStep`: present → render the matching page. Absent → check `processStatus` ∈ {Completed, PendingReview} → emit `KycCompleted` / `KycPending`  5. `_legalDisclaimerAccepted` / `_registrationSignProduced` stay as session security gates BUT no longer drive routing — they only let the app respond when API tells it to show the registration page  6. Drop the `requiredLevel` constructor parameter — it's dead once `canTrade` exists  7. Delete the same `kycSteps.firstWhere(step.isCurrent)` loop in `_continueKyc` (line 208) — that's V45, the parallel path called after registration completes; same `currentStep`-driven rewrite applies |
+| Acceptance | Replay the 2026-05-21 reproduction: user 338759 with InProgress Ident step opens app → API returns `currentStep: ident`. App renders KycIdentPage. **No local computation needed.** Hand-test: clear the InProgress Ident in DB → API returns no currentStep + `canTrade: true` → app lands on Dashboard |
+| Test plan | Cubit tests: 1) Mock API: `canTrade: true, currentStep: null, processStatus: Completed` → emit `KycCompleted`. 2) Mock API: `currentStep: {name: 'Ident', status: 'InProgress'}` → emit `KycSuccess(KycStep.ident)`. 3) Mock API: `processStatus: PendingReview, currentStep: null` → emit `KycPending`. Verify cubit code length drops by ~80% |
+| Risk | Med — central routing logic. Mitigate with extensive cubit tests covering every state the API can return |
+| Effort | M (~1–1.5 days including test rewrite) |
+
+**Wave 2 total:** ~2.5 dev-days. **Closes the original incident** + structurally removes 7 audit findings (V1, V2, V3, V5, V21, V22, V45).
+
+---
+
+## Wave 3 — Capability flags + structured registration response
+
+Closes the rest of the P0/P1 KYC-adjacent items.
+
+### W3.1 (API PR) — User capabilities + structured registration error
+
+| | |
+|---|---|
+| Closes | V6a, V6b, V6c, V6d, V9, V15, V16, V43, V46 |
+| Repo | DFXswiss/api, branch `feat/user-capabilities` |
+| Changes | 1. `UserV2Dto`: add `capabilities: UserCapabilitiesDto { canEditName: bool, canEditMail: bool, canEditPhone: bool, canEditAddress: bool, supportAvailable: bool, availableUserTypes: string[] }`. Computed from KYC step states and other server-side conditions. `availableUserTypes` lets the registration screen render only the account types this branded app exposes instead of hardcoding `RegistrationUserType.values.first`. (Closes V6a, V6b, V6c, V9, V46.) Additionally expose a `category` on `KycStepDto` (e.g. `'changeRequest' | 'registration' | 'verification'`) so the app can filter change-flow steps without a hardcoded `_changeStepNames` set. (Closes V6d.)  2. `RealUnitRegistrationStatus` (`src/.../realunit-registration.dto.ts:26-30`): add `ALREADY_REGISTERED`. Change `realunit.service.ts:608, 670` from `throw BadRequestException` to `return RealUnitRegistrationStatus.ALREADY_REGISTERED` (different-signature path still throws — [`DFXswiss/api#3731`](https://github.com/DFXswiss/api/pull/3731) handles that nuance). (Closes V15.)  3. `SellPaymentInfoDto`: add `@ApiPropertyOptional() requiredWorkflow?: 'standard' \| 'sellBitbox' \| 'gasless'`. Compute server-side based on user wallet type + asset chain. (Closes V16.)  4. `KycFinancialQuestion` DTO: add `link?: { url?: string, action?: 'support' \| 'webview' }` so the financial-data questions page can render the right action target from the DTO instead of switching on `question.key`. (Closes V43.) |
+| Acceptance | `GET /v2/user` includes `capabilities`. `POST /realunit/register/wallet` for already-registered same-wallet returns 201 + `ALREADY_REGISTERED` (not 400). `PUT /sell/paymentInfos` includes `requiredWorkflow` |
+| Test plan | New unit tests for the mapper (`user.mapper.spec.ts`): InReview KYC user → `canEditName: false`. No-mail user → `supportAvailable: false`. Realunit service test for `ALREADY_REGISTERED` path. Sell-payment-info service: BitBox-credentials → `requiredWorkflow: 'sellBitbox'` |
+| Risk | Med — `capabilities` is a new contract; missing a flag means apps stay on local logic. Be exhaustive |
+| Effort | M (~1.5 days) |
+
+### W3.2 (App PR) — Consume capabilities + ALREADY_REGISTERED + requiredWorkflow
+
+| | |
+|---|---|
+| Closes | V6a, V6b, V6c, V6d, V9, V15, V16, V43, V46 |
+| Repo | DFXswiss/realunit-app, branch `refactor/use-user-capabilities` |
+| Changes | 1. `settings_user_data_page.dart:239` + `settings_edit_name_cubit.dart:22` + `settings_edit_address_cubit.dart:22`: drop status interpretation → `user.capabilities.canEditName` / `canEditAddress` (V6a/V6b/V6c)  2. `settings_user_data_cubit.dart:18-22`: delete `_changeStepNames` set → use the new step `category` flag or API capabilities to filter change-flow steps (V6d)  3. `settings_contact_page.dart:54-67` + `settings_contact_cubit.dart:22`: drop email check (both the cubit's `emailSet` computation and the page's read of it) → `user.capabilities.supportAvailable` (V9)  4. `kyc_registration_submit_cubit.dart:76, 92`: drop the "treat error as success" hack — handle `ALREADY_REGISTERED` as an explicit success status returned by the API (V15)  5. `sell_button.dart:60-62`: drop `isBitbox` local check → `state.paymentInfo.requiredWorkflow == 'sellBitbox' ? AppRoutes.sellBitbox : AppRoutes.sell` (V16)  6. `kyc_financial_data_questions_page.dart:110-122`: render the question's `link` metadata instead of switching on `question.key` (V43)  7. `kyc_registration_personal_step.dart:50-53`: read `user.capabilities.availableUserTypes` instead of `RegistrationUserType.values.first` (V46) |
+| Acceptance | All four spots stop interpreting status / wallet type / exception body |
+| Risk | Low (App-side, mechanical) |
+| Effort | M (~1 day) |
+
+**Wave 3 total:** ~2.5 dev-days.
+
+---
+
+## Wave 4 — New endpoints (legal docs, company info, country priority)
+
+The remaining P2 items that require entirely new API surface. Lower urgency — no user is blocked today by these.
+
+### W4.1 (API PR) — `GET /v1/legal-document`
+
+| | |
+|---|---|
+| Closes | V17, V44 |
+| Repo | DFXswiss/api, branch `feat/legal-document-endpoint` |
+| Changes | New module `src/shared/models/legal-document/`: entity (`type, language, version, url, enabled`), repository, service, controller (`GET /v1/legal-document`, optional `?type=` and `?language=` filters), DTO. Migration creates `legal_document` table with seed data from the current `lib/packages/config/legal_documents_config.dart` hardcoded URLs **plus** the `dfx.swiss/terms-and-conditions` URL hardcoded in `lib/screens/kyc/steps/financial_data/constants/kyc_financial_data_links.dart` (V44). Admin endpoint to update URLs (compliance role) |
+| Acceptance | `GET /v1/legal-document?type=registrationAgreement&language=de` returns the agreement PDF URL + current version |
+| Risk | Low — net-new module, no existing behavior touched |
+| Effort | M (~2 days, mostly seed-data + admin endpoints) |
+
+### W4.2 (API PR) — `GET /v1/company-info`
+
+| | |
+|---|---|
+| Closes | V18 |
+| Repo | DFXswiss/api, same branch as W4.1 or separate |
+| Changes | New module + endpoint returning company contact info for the realunit-app brand. Public (no auth). Future-proofs white-labeling |
+| Effort | S (~half day) |
+
+### W4.3 (API PR) — Country priority + recommended language + recommended currency
+
+| | |
+|---|---|
+| Closes | V14, V19, V41, V42 |
+| Repo | DFXswiss/api, branch `feat/country-priority-recommended-language` |
+| Changes | 1. `GET /v1/country` accepts `?priorityForRegion=CH` query → returns countries sorted with Swiss-preferred ones first. Or simpler: add `displayOrder: int` to the country entity for backend-configurable priority  2. `UserV2Dto` (or new endpoint `GET /v1/language/recommended?ip=…&acceptLanguage=…`): return a recommended language code (V19) **and** a recommended currency (V42 — same shape, paired so the app picks both defaults in one round-trip)  3. The realunit-registration endpoint derives the account language from the `Accept-Language` header (or the user's settings-language sent in the body), so the app no longer needs to send `lang: 'DE'` (V41) |
+| Effort | S |
+
+### W4.5 (API PR) — `GET /v1/support/issue-types`
+
+| | |
+|---|---|
+| Closes | V49 |
+| Repo | DFXswiss/api, branch `feat/support-issue-types-endpoint` |
+| Changes | New `GET /v1/support/issue-types` endpoint returning `{ key, icon, label }[]` (or i18n-key-only with the app holding the translations). Per-brand: realunit returns a curated subset, other apps can expose different subsets. Replaces the hardcoded `SupportIssueType` tile list + the English-only `_getTicketName` labels in the app |
+| Acceptance | `GET /v1/support/issue-types` returns a list keyed to the existing `SupportIssueType` values; new categories appear without an app release |
+| Effort | S |
+
+### W4.4 (App PR) — Consume W4.1–W4.3, W4.5
+
+| | |
+|---|---|
+| Closes | V14, V17, V18, V19, V41, V42, V44, V49 |
+| Changes | 1. Delete `lib/packages/config/legal_documents_config.dart` hardcoded URLs **and** `lib/screens/kyc/steps/financial_data/constants/kyc_financial_data_links.dart` (V44) → call `/v1/legal-document`. Cache locally for offline  2. Delete hardcoded contact info in `settings_contact_page.dart:82-134` → render from `/v1/company-info`. Cache  3. Delete `priorityCountries` in `country_field.dart:65-79` → use API order  4. Replace `settings_repository.dart:18-24` (language fallback) **and** `settings_repository.dart:28` (currency fallback, V42) with API recommendations; system-locale fallback only on first-launch-no-network  5. Drop the hardcoded `lang: 'DE'` in `real_unit_registration_service.dart:117` (V41) → send the user's actual settings-language (or rely on the `Accept-Language` header)  6. Replace the hardcoded `SupportIssueType` tile list in `support_create_ticket_page.dart:85-110` and the English-only `_getTicketName` switch in `support_create_ticket_cubit.dart:48-57` with the API-returned list (V49) |
+| Effort | M (~1.5 days) |
+
+**Wave 4 total:** ~4 dev-days.
+
+---
+
+## Wave 5 — Remaining P1/P2 (JWT merge, polling, transaction state, account bounds, asset config)
+
+The tail items the first four waves don't cover. Lower urgency than Waves 1–3 but explicitly tracked so the audit can be driven to zero actionable items.
+
+### W5.1 (API PR) — Idempotent merge-detection + transaction status label + account bounds + auto-register
+
+| | |
+|---|---|
+| Closes | V20, V23, V24, V26, V27, V31, V32, V47, V48 |
+| Repo | DFXswiss/api, branch `feat/api-authority-tail` |
+| Changes | 1. `POST /v1/realunit/register/wallet` (or new `POST /v1/kyc/check-merge`): return `{ merged: bool, mergedAccountId?: string, propagated: bool }` directly. Server polls internally until propagated, so the client does not need its own generation/retry orchestration. (Closes V23, V26, V27.)  2. `Transaction` mapper: add `statusKey: string` and `statusLabel: string` so the app renders text instead of switching on `state == waitingForPayment`. (Closes V24.)  3. New `GET /v1/user/account-bounds` returning `{ firstTransactionDate, lastTransactionDate }` — both `transaction_history_page.dart:68-69, :82` and `settings_tax_report_page.dart:73` use it for `firstDate`. (Closes V31, V32.)  4. Auto-registration of email at `level < 10` becomes server-side: `PUT /v2/kyc` performs it before returning `currentStep`. App stops doing `if (level < 10) register()`. (Closes V20.)  5. `/v1/realunit/balance/pdf` accepts a `date` (not a timestamp); the server picks the evaluation moment (today → "now"; past date → end-of-day). The app stops computing `_getDateWithLatestTime`. (Closes V47.)  6. `SellPaymentInfoDto` exposes `needsFaucet: bool` and optionally `faucetPollingHint: int` (seconds), computed server-side from `ethBalance` vs `requiredGasEth`. The bitbox-sell cubit renders the boolean + uses the hint as the polling interval instead of comparing the two numbers locally. (Closes V48.) |
+| Acceptance | (1) Client calls `check-merge` exactly once → no client-side 30s timeout needed. (2) `pending_transaction_row.dart` switches on `statusKey`, not on the typed enum. (3) Pickers' `firstDate` comes from API. (4) New-user flow shows `currentStep: 'email'` without the app pre-calling register. (5) Tax-report download sends a date, server picks the timestamp. (6) Bitbox-sell shows the faucet-pending UI when `needsFaucet: true` without comparing balances. |
+| Risk | Med — V20 in particular changes when the email registration POST fires; needs careful regression testing. |
+| Effort | M (~2.5 days) |
+
+### W5.2 (API PR) — Asset configuration endpoint
+
+| | |
+|---|---|
+| Closes | V29 |
+| Repo | DFXswiss/api, branch `feat/realunit-asset-config` |
+| Changes | `GET /v1/asset?app=realunit` returns the canonical RealUnit token configuration (address, chainId, decimals, mainnet + Sepolia). App reads this on boot and caches per network mode. Replaces hardcoded `ApiConfig` constants. |
+| Acceptance | App calls `/v1/asset?app=realunit` after `NetworkMode` is resolved (the boot-time API host is still local), and uses the returned config for chainId/address/decimals. |
+| Risk | Low (read-only endpoint, additive) |
+| Effort | S (~half day) |
+
+### W5.3 (App PR) — Consume W5.1 + W5.2
+
+| | |
+|---|---|
+| Closes | V20, V23, V24, V26, V27, V29, V31, V32, V47, V48 |
+| Repo | DFXswiss/realunit-app, branch `refactor/api-authority-tail` |
+| Changes | Apply the per-item changes from W5.1 + W5.2 in the app: delete `_runGeneration` (kyc_cubit.dart:42-69), `_mergeDetected` orchestration (kyc_email_verification_cubit.dart:24-37), JWT-decode merge detection (kyc_email_verification_cubit.dart:49-63), the `level < 10 → register` branch (kyc_cubit.dart:88-104), the pending-row state switch (pending_transaction_row.dart:49-51), the picker `firstDate` constants (transaction_history_page.dart:68-69, :82 and settings_tax_report_page.dart:73), the hardcoded `ApiConfig` token block (api_config.dart:19-22), the `_getDateWithLatestTime` transform in `settings_tax_report_cubit.dart:53-64` (V47), and the local ETH-balance-vs-required-gas comparisons in `sell_bitbox_cubit.dart:51, :81` (V48 — replace with `_paymentInfo.needsFaucet`). |
+| Risk | Med — JWT decode and polling are critical paths; cover with cubit tests before merge. |
+| Effort | M (~2 days) |
+
+### Out of scope — explicitly accepted boundary cases
+
+These items appear in the audit but are **not** closed by any wave. Future PRs should not try to "fix" them.
+
+| Item | V-ID | Why out of scope |
+|---|---|---|
+| `lib/packages/utils/default_assets.dart:3-22` (ETH/ZCHF asset IDs) | V30 | The app **is** the RealUnit wallet; the default asset list is part of the product identity, not a backend decision. Revisit only if a multi-asset use case emerges. |
+| `lib/packages/config/network_mode.dart` (`mainnet` / `testnet`) | V28 | Determines *which* API host the app talks to — cannot itself be API-driven (chicken-and-egg). |
+| BIP-39 12-word check (`settings_seed_view.dart:98`) | V33 | Structural crypto invariant. |
+| `WalletType == software` for backup visibility (`settings_page.dart:100`) | V13b | Device-capability fact; BitBox cannot expose its seed. |
+| `401 → token refresh` (`dfx_auth_service.dart:233-239`) | V25 | HTTP-standard convention; the 401 contract is contractual. |
+
+**Wave 5 total:** ~4.5 dev-days.
+
+---
+
+## Documented exceptions — the rule explicitly does not apply
+
+These are listed in the audit ([`api-authority-audit.md`](api-authority-audit.md) P3/P4) and documented here as accepted exceptions. Future maintainers should not "fix" these into the audit again.
+
+| Exception | Reason |
+|---|---|
+| `NetworkMode { mainnet, testnet }` (`api_config.dart`) | Chicken-and-egg: the network mode determines *which* API the app calls. Cannot itself come from the API |
+| BIP-39 seed = 12 words (`settings_seed_view.dart:98`) | Structural crypto invariant, not a business rule |
+| `WalletType == software` check for backup visibility | Physical reality: a BitBox cannot expose its seed; this is a device-capability fact, not a backend policy |
+| `401 → token refresh` (`dfx_auth_service.dart:233-239`) | HTTP-standard convention; the 401 contract is well-defined and external |
+| PIN validation, wallet lock, BitBox connection state | Local security boundary; API has no view of device-side security state |
+| EIP-712 signing, hashing, key derivation | Must run locally on the user's device |
+| DTO mirroring (`KycLevel`, `KycStepName`, etc. enums) | Type safety; values must stay in sync but mirroring is acceptable boilerplate |
+
+---
+
+## Sequencing & dependencies
+
+```
+Wave 1  (app-only, no API dep)                ── ship first, validates mechanics
+Wave 2  W2.1 API  ──►  W2.2 App               ─┐
+Wave 3  W3.1 API  ──►  W3.2 App               ─┤  Waves 2/3/4/5 independent
+Wave 4  W4.1–W4.3 API  ──►  W4.4 App          ─┤  of each other —
+Wave 5  W5.1 + W5.2 API  ──►  W5.3 App        ─┘  ship in parallel if 2 devs
+```
+
+- Wave 1 has no API dependency; ship it first to validate the pair-PR mechanics on something low-risk.
+- Within each later wave, the API PR strictly blocks the App PR (`──►` arrow).
+- Waves 2, 3, 4, 5 are **independent of each other** — they touch disjoint API surface and disjoint app surface, so any two devs can pick two waves and run them concurrently after Wave 1 lands.
+
+**Aggressive timeline (2 devs, parallel):** ~2.5 weeks calendar.
+**Conservative timeline (1 dev, sequential):** ~7 sprints / 14 weeks calendar.
+
+---
+
+## Risk register
+
+| Risk | Likelihood | Impact | Mitigation |
+|---|---|---|---|
+| API field added but never consumed (audit regresses) | Med | High | Pair-PR convention enforced in PR review checklist |
+| `canTrade` semantics drift from current implicit rule | Med | High | Fixture-based mapper tests covering edge cases (level 53 + outdated ident) BEFORE Wave 2.2 ships |
+| Old app version + new API: missing field crashes | Low | Med | All API additions are optional / nullable; app handles `null` gracefully |
+| Compliance objection to `canTrade` based on level only | Low | High | `canTrade` is computed server-side from the *same* signals the app uses today (level + step state) — semantic identity, not relaxation. Loop in compliance before W2.1 merge |
+| Legal-document migration data error | Med | Low | Seed script runs in a dry-run + diff-review mode first; admin endpoint allows hotfix |
+
+---
+
+## Forward contract
+
+Once this plan is executed:
+
+- New PRs that introduce a violation pattern (local `_requiredX`, status enum interpretation, hardcoded business limit) are **blocked** by review until the API field exists.
+- The CONTRIBUTING.md rule is enforceable: every Reviewer can point at this plan and ask *"which wave does your change belong to?"* If the answer is "none — I added a new local decision", the PR doesn't merge.
+- Audit ([`api-authority-audit.md`](api-authority-audit.md)) becomes a regression test: ideally only shrinks PR by PR.
+
+---
+
+## What to do next (concrete first action)
+
+1. **Now:** review this plan + the audit doc. Decide if any item is mis-prioritized.
+2. **Day 1:** open W1.1 + W1.2 + W1.5 as small App-only PRs. They're the lowest-risk validation that the pair-PR mechanics work.
+3. **Day 2:** open W2.1 (API) as the first paired wave. Loop in compliance on the `canTrade` semantics before merge.
+4. **Day 3-4:** open W2.2 (App) once W2.1 is on `develop`.
+5. **Day 5+:** schedule Wave 3, Wave 4, and Wave 5 in the regular sprint planning. Waves 2–5 are independent and can run concurrently if staffed.
+
+---
+
+## Lessons learned — Wave 3 reset (2026-05-26)
+
+Wave 3 went through four iterations before landing in a stable shape. The pattern is generalisable to every future capability we add — if you're tempted to expose anything richer than a bool flag, read this section first.
+
+### The PR sequence
+
+| PR | Direction | Outcome | Why |
+|---|---|---|---|
+| [api#3733](https://github.com/DFXswiss/api/pull/3733) | API: `+supportAvailable: bool` | merged | First Wave-3 cut — added a bool to `UserCapabilitiesDto` per the original plan |
+| [app#497](https://github.com/DFXswiss/realunit-app/pull/497) | App: consume `supportAvailable` bool | merged | Companion app PR; tile-visibility tied to the bool |
+| [app#588](https://github.com/DFXswiss/realunit-app/pull/588) | App: unconditional Support tile | merged | UX feedback: tile must stay visible pre-signin for discoverability, hiding it on `!supportAvailable` was wrong |
+| [api#3761](https://github.com/DFXswiss/api/pull/3761) | API: `-supportAvailable: bool` | merged | After #588 the bool had no consumer; deleted backend-side |
+| [api#3767](https://github.com/DFXswiss/api/pull/3767) | API: `+ActionCapability` tree (4 DTOs, HttpMethod enum, 170 LOC) | **closed without merge** | First attempt at the structured replacement; @davidleomay correctly flagged the over-engineering — static endpoint paths don't belong in dynamic responses |
+| [api#3772](https://github.com/DFXswiss/api/pull/3772) | API: `+createSupportTicket: { available, missingPrerequisite? }` (91 LOC) | merged | Minimum compromise — per-user runtime info only, static paths stay in Swagger via `@ApiBadRequestResponse` |
+
+Net result: V9 closed end-to-end with **less LOC than the original bool-only path** plus the proper discoverable UX. But it took five days and six PRs.
+
+### What we'd do differently next time
+
+1. **Specify the UX requirement before designing the capability shape.** The bool was correct *for the original UX* (tile hides when unavailable). The UX changed (tile must stay visible) and we didn't re-derive the schema from the new requirement — we just deleted the bool. Re-deriving would have produced the discriminator shape directly.
+2. **Push back on capability complexity at PR time, not after merge.** David's review on #3767 caught the over-engineering before merge — that's the model. If a capability shape isn't justified by the UX requirement, the reviewer flags it; reductions are easier than rollbacks.
+3. **Static info goes in Swagger.** This is the most important takeaway. `@ApiBadRequestResponse` decorators let the API document the remediation path without shipping it on every request. The `createSupportTicket` capability ships **only** the per-user runtime state (`available` + the prerequisite discriminator) — paths are documented, not transmitted.
+
+### The eight binding rules
+
+Both repos now document the eight rules synthesised from this exercise. Read them before adding any new capability:
+
+- API side: [`DFXswiss/api:CONTRIBUTING.md`](https://github.com/DFXswiss/api/blob/develop/CONTRIBUTING.md) → "API Capability Design".
+- App side: [`CONTRIBUTING.md`](../CONTRIBUTING.md) → "Consuming API capabilities — eight rules" inside the "API as Decision Authority" section.
+
+Rules 2 (static info in Swagger), 3 (YAGNI for enum members), 6 (pair-PR with documented trade-off), and 8 (reduction before extension) are directly attributable to @davidleomay's review pressure on this Wave.
+
+### Forward — what this means for Waves 4 and 5
+
+- Wave 4 (`legal-document`, `company-info`, `support-issue-types`, country priority) is mostly **list / config endpoints** — these don't need capability shapes. Plain DTOs.
+- Wave 5 (JWT merge, polling, transaction state, account bounds, asset config) has at least one discoverable-action shape (account-merge-on-email-conflict) — that one should use the `{ available, missingPrerequisite? }` pattern from Wave 3, not invent a new shape.
+- Future capabilities not yet planned: default to the heterogeneous rule — `bool` for hide-able, struct only when the user must be guided through a prerequisite.

+# RealUnit Handbook
+
+User-Guide + Test-Doku in einem. Jeder Screenshot ist eine Visual-Regression-
+Golden-Baseline aus `test/goldens/screens/`; das Handbook bleibt nur dann
+visuell korrekt, wenn die App es auch ist — eine Drift im echten Seitenrendering
+flippt den entsprechenden Golden-Test rot, bevor das Handbook-Image gebaut wird.
+
+## Lokal lesen
+
+```bash
+# 1. Screenshots aus Goldens lokal in docs/handbook/screenshots/ assemblieren
+#    (Verzeichnis ist gitignored; wird nur fürs lokale Preview befüllt)
+bash scripts/assemble-handbook-screenshots.sh docs/handbook/screenshots
+
+# 2. HTML im Browser öffnen — kein Web-Server nötig
+open docs/handbook/de/index.html
+```
+
+Den gleichen Multi-Stage-Build macht `Dockerfile.handbook` automatisch beim
+deployten Image (`handbook.realunit.app` / `dev-handbook.realunit.app`).
+
+## Screenshots regenerieren
+
+Es gibt keinen separaten Regeneration-Schritt: Die 52 Handbook-Screenshots
+sind direkt die Golden-Baselines unter `test/goldens/screens/` (gemappt in
+`scripts/assemble-handbook-screenshots.sh`). Eine UI-Änderung an einer der
+gemappten Pages produziert beim `flutter test test/goldens` einen Diff —
+diesen via `golden-regenerate.yaml` auf dfx01 regenerieren lassen, und der
+nächste Handbook-Deploy zeigt das aktualisierte Bild.
+
+Workflow:
+
+1. Page in `lib/screens/**/*_page.dart` ändern
+2. `flutter test test/goldens/screens/<feature>` läuft rot mit Diff-Artefakt
+3. `gh workflow run golden-regenerate.yaml --ref <branch>` — der Workflow
+   regeneriert auf dfx01 und committet die neuen PNGs als
+   `github-actions[bot]` zurück auf den Branch (siehe
+   [`../visual-regression-tests.md`](../visual-regression-tests.md))
+4. Pullen → der nächste Handbook-Deploy zeigt die neue Baseline automatisch
+   (Push auf `staging` → DEV bzw. `develop` → PRD).
+
+## Selektive Läufe (Teilmenge)
+
+`scripts/run-handbook-flows.sh` akzeptiert optionale Argumente: Glob-Muster auf
+die Flow-Namen. Ohne Argument laufen alle Flows, mit Argument nur die passende
+Teilmenge:
+
+```bash
+# Nur diesen einen Flow
+scripts/run-handbook-flows.sh 25-restore-wallet
+
+# Die ganze 20er-Serie (20..26)
+scripts/run-handbook-flows.sh '2*'
+```
+
+Achtung: Die handbook-Flows sind eine **sequentielle Kette** und teilen sich den
+App-State — jeder Flow greift den Zustand auf, wo der vorherige ihn hingelegt
+hat. Ein Flow aus der Mitte der Kette schlägt einzeln fehl, sofern er nicht
+selbst mit einem `launchApp` beginnt. Der Flow `26-terms` ist **eigenständig**
+(eigener `launchApp`) und kann daher gefahrlos allein laufen.
+
+Auch der Tier-3-GitHub-Workflow hat dafür einen `flows`-`workflow_dispatch`-Input
+— so lässt sich in der CI gezielt eine Teilmenge der Flows als Navigation-Smoke
+neu laufen lassen. (Die Screenshots zieht das Handbook aus den Goldens, nicht
+mehr aus diesen Maestro-Läufen.)
+
+## Einen neuen Handbook-Eintrag hinzufügen
+
+1. **Page + Golden-Test**: `lib/screens/<feature>/<name>_page.dart` + zugehörigen
+   Golden-Test unter `test/goldens/screens/<feature>/`. Pattern siehe
+   [`../visual-regression-tests.md`](../visual-regression-tests.md) und bestehende
+   Tests in `test/goldens/screens/`.
+2. **Screenshot-Mapping**: in `scripts/assemble-handbook-screenshots.sh` eine neue
+   Zeile in der `MAPPING`-Tabelle ergänzen — `"NN-<name>=<feature>/goldens/macos/<file>.png"`.
+   Die Nummer NN ist der Sortierschlüssel im Handbook (keine direkte Bindung mehr
+   an einen Maestro-Flow).
+3. **HTML**: in `docs/handbook/de/index.html` einen neuen `<div class="test">`-Block
+   in die thematisch passende `<details id="spec-NN" class="spec">`-Sektion
+   einfügen (Muster siehe spec-01). Die Screenshots sind in wenige thematische
+   spec-Sektionen gruppiert — ein neuer Eintrag kommt meist in eine bestehende.
+4. **Nur bei einem neuen Thema**: eine neue `<details id="spec-NN" class="spec">`
+   anlegen und den Anker `#spec-NN` in `<nav class="toc">` ergänzen.
+5. **Optional — Tier-3-Smoke**: zusätzlich `.maestro/handbook/NN-<name>.yaml` für
+   den Navigation-/Tap-Routing-Smoke anlegen (siehe "Einen neuen Maestro-Flow
+   hinzufügen" unten). Nicht zwingend für jeden neuen Handbook-Eintrag — nur wenn
+   ein neuer User-Pfad durch die App geprüft werden soll.
+
+### Einen neuen Maestro-Flow hinzufügen (Tier-3-Smoke)
+
+1. Anlegen: `.maestro/handbook/NN-<name>.yaml`.
+   - Erster Flow startet mit `launchApp: clearState: true`.
+   - Folgeflows starten ohne `launchApp` — sie greifen den App-State auf,
+     wo der vorherige Flow ihn hingelegt hat.
+   - Beende mit `assertVisible` oder `extendedWaitUntil`, damit die Assertion
+     stabil ist (sonst trifft Maestro mitten in der Transition).
+2. Lauf: `scripts/run-handbook-flows.sh` (lokal) bzw. Tier-3-CI auf PR.
+
+## E-Mail Previews
+
+Die HTML-Vorschauen aller vom Backend an Endkunden versendeten Mails liegen
+**nicht in diesem Repo**. Quelle ist `DFXswiss/api`:
+
+- Generator: `scripts/generate-realunit-previews.js`
+- Vorlage: `src/subdomains/supporting/notification/templates/realunit.hbs`
+- Übersetzungen: `src/shared/i18n/de/mail-realunit.json` (RealUnit-Texte) mit
+  Fallback auf `src/shared/i18n/de/mail.json` (DFX-Defaults)
+
+Der Handbook-CI-Build (`.github/workflows/handbook.yaml`) checkt das api-Repo
+zur Build-Zeit aus, führt den Generator aus und kopiert das Ergebnis nach
+`docs/handbook/mails/`, bevor das Docker-Image gebaut wird. `docs/handbook/mails/`
+ist in `.gitignore` — der Inhalt darf nie ins Repo eingecheckt werden, sonst
+divergieren Image-Stand und Source-of-Truth.
+
+### Trigger
+
+Der Handbook-Deploy läuft pro Branch in genau ein Environment: ein `push`
+auf `staging` deployt nach **DEV** (`dev-handbook.realunit.app`), ein `push`
+auf `develop` nach **PRD** (`handbook.realunit.app`) — jeweils mit Änderungen
+unter handbook-relevanten Pfaden (siehe `handbook-deploy.yaml`) oder per
+manuellem `workflow_dispatch` auf `handbook-deploy.yaml` in **diesem** Repo
+(das Ziel-Environment richtet sich nach dem dispatchten Branch). DEV und PRD
+nutzen getrennte Image-Tags (`:beta` bzw. `:latest`), damit sich staging- und
+develop-Builds nicht gegenseitig überschreiben. Eine reine Mail-Template-,
+i18n- oder Generator-Änderung im api-Repo löst **keinen** automatischen
+Rebuild aus — sie fliesst erst mit dem nächsten Handbook-Deploy hier rein.
+
+Wer eine reine Mail-Änderung sofort live haben will, hat zwei Optionen
+im realunit-app-Repo:
+
+```bash
+# Variante A: No-op-Touch unter einem handbook-relevanten Pfad,
+# damit der path-Filter von handbook-deploy.yaml zieht. `--allow-empty`
+# alleine reicht NICHT — der Push muss eine Datei unter docs/handbook/
+# (oder Dockerfile.handbook / handbook.nginx.conf / handbook.htpasswd /
+# einen der beiden handbook-Workflows) tatsächlich anfassen.
+touch docs/handbook/.sync && git add docs/handbook/.sync \
+  && git commit -m "chore(handbook): pull latest mail templates from api" \
+  && git push origin develop
+
+# Variante B: manuell dispatchen (kein Commit nötig)
+gh workflow run handbook-deploy.yaml --ref develop
+```
+
+### Lokal regenerieren
+
+Mit beiden Repos nebeneinander ausgecheckt — alle Befehle laufen im
+realunit-app-Root. Wir installieren handlebars **isoliert** in einen scratch
+Prefix (`_handlebars-only/`), genau wie der CI-Step in `handbook.yaml`. So
+bleiben `package.json` und `package-lock.json` im api-Klon unangetastet
+(sonst wäre `git status` im api-Repo nach dem Repro dreckig).
+
+```bash
+# 1. handlebars isoliert installieren (idempotent — kann beliebig oft laufen)
+npm install --prefix ./_handlebars-only --no-save --no-audit --no-fund handlebars
+
+# 2. Generator aus dem api-Repo ausführen (NODE_PATH zeigt auf den scratch-Install)
+NODE_PATH="./_handlebars-only/node_modules" \
+  node ../api/scripts/generate-realunit-previews.js
+
+# 3. Ergebnis ins Handbook übernehmen
+mkdir -p docs/handbook/mails
+cp ../api/scripts/email-previews/realunit/*.html docs/handbook/mails/
+cp docs/handbook/mails/00_index.html docs/handbook/mails/index.html
+
+# 4. Lokal ansehen
+open docs/handbook/mails/index.html
+
+# 5. Scratch-Dir aufräumen (in .gitignore — aber sauber ist sauber)
+rm -rf ./_handlebars-only
+```
+
+(Den finalen Build-Step macht aber immer der CI — lokale Files sind nur fürs
+Vorab-Anschauen während eines Template-Refactors.)
+
+## Beziehung zu den Tier-0/Tier-1-Tests
+
+Tier 0/1 (Unit + Widget + integration-mit-FakeBitboxCredentials) prüfen
+einzelne Methoden / Zustände / Branches. Tier 3 (Maestro) prüft den
+User-Journey-Layer drüber: dass die Pages in der richtigen Reihenfolge
+erscheinen und ihre Inhalte korrekt rendern. Beide Tiers ergänzen sich;
+keiner ersetzt den anderen. Siehe [`../testing.md`](../testing.md).

+# App Screens
+
+Complete inventory of every screen in the RealUnit wallet app — one row per screen.
+
+The source of truth for navigable screens is the `GoRouter` definition in
+`lib/setup/routing/router_config.dart`; route names live in
+`lib/setup/routing/routes/`. Keep this file in sync when routes, screen widgets
+or handbook screenshots change.
+
+Column meaning:
+
+- **Route** / **Path** — the `GoRoute` name and path. `—` means the screen is
+  **not a route**: it is shown inside a parent route (KYC steps, status
+  sub-pages, disclaimer steps).
+- **Handbook** — the handbook screenshot slot number(s) that document the
+  screen, or `—` if it is not in the handbook. Each slot is a Visual-Regression
+  Golden under `test/goldens/screens/`, mapped to its handbook position by
+  `scripts/assemble-handbook-screenshots.sh`. The handbook covers the
+  new-user onboarding journey (sign-up → dashboard) plus the settings screens
+  reachable from it plus the financial-state variants of Buy/Sell/Dashboard/
+  TransactionHistory and the legal/KYC step widgets: **52 slots in total**,
+  spread across **20 distinct routed pages**. The table below indexes only
+  the 20 anchors; the remaining 32 slots are state-variant renderings of
+  those same screens (a few inline in the 01–26 range — e.g. slot 05 is
+  `CreateWalletPage` with the seed revealed and slot 09 is `SetupPinPage`
+  in confirm mode — plus the full 27–52 range: Buy/Sell error banners,
+  KYC loading/failure, Dashboard with-balance, Legal-Disclaimer steps,
+  etc.). Slot ↔ Golden mapping in
+  `scripts/assemble-handbook-screenshots.sh`, slot ↔ HTML block in
+  `docs/handbook/de/index.html`. See `docs/handbook/README.md`.
+
+| Area | Widget | Route | Path | Handbook |
+|---|---|---|---|---|
+| Onboarding | `HomePage` | `home` | `/home` | `01` |
+| Onboarding | `WelcomePage` | `welcome` | `/welcome` | `02`, `03` |
+| Onboarding | `CreateWalletPage` | `createWallet` | `/createWallet` | `04`, `05` |
+| Onboarding | `VerifySeedPage` | `verifySeed` | `/verifySeed` | `06` |
+| Onboarding | `RestoreWalletPage` | `restoreWallet` | `/restoreWallet` | `25` |
+| Onboarding | `OnboardingCompletedPage` | `onboardingCompleted` | `/onboardingComplete` | `07` |

+65 screens — 40 routed (`GoRoute`) + 25 non-routed.
+
+## Notes
+
+- **Non-routed screens** are driven inside a parent route: the KYC pages are
+  orchestrated by `KycPageManager` under `/kyc`; the `*Step` widgets are steps
+  inside a parent (`LegalDisclaimerStep` etc. inside `LegalDisclaimerPage`,
+  `KycRegistration*Step` inside `KycRegistrationPage`); the `*Loading` /
+  `*Pending` / `*Failure` pages are operation-status screens.
+- **`debugAuth`** is registered only in debug builds (`kDebugMode`).
+- **Shared widgets.** `LegalDocumentPage` backs two routes (`legalDocument`,
+  `terms`); `VerifyPinPage` backs two (`pinGate`, `verifyPin`) via different
+  constructors. Handbook screenshot `17` shows `VerifyPinPage` in its `pinGate`
+  use; the `verifyPin` app-lock use is not separately documented.
+- **Handbook numbering.** Each of the 52 handbook slots is a Visual-Regression
+  Golden under `test/goldens/screens/`, mapped to its handbook position by
+  `scripts/assemble-handbook-screenshots.sh`. A parallel Tier-3 Maestro flow
+  (`.maestro/handbook/NN-*.yaml`) covers the same screen for navigation/
+  tap-routing smoke but does not produce the handbook image. Slot
+  `10-biometric-prompt` documents the `EnableBiometricBottomSheet` modal — not
+  a routed screen — so the table has no `10`.
+- **`*Page` / `*View` pattern.** Several screens split into a `*Page` widget
+  (provides the bloc/cubit) and a `*View` widget (builds the `Scaffold`):
+  `CreateWalletView`, `RestoreWalletView`, `SettingsSeedView`, `DebugAuthView`.
+  These are not separate screens — each belongs to its `*Page`.
+- **Modal bottom sheets** are not screens and are out of scope: e.g.
+  `EnableBiometricBottomSheet`; `ReceivePage` in `isBottomSheet` mode;
+  `ConnectBitboxPage` — despite its `Page` suffix it builds no `Scaffold` and is
+  shown via `showModalBottomSheet`.

+# Testing Guide
+
+RealUnit's tests are organised into five tiers (see [#314](https://github.com/DFXswiss/realunit-app/issues/314)). Each tier trades off fidelity for cost; pick the lowest tier that still proves the behaviour you care about.
+
+| Tier | What it exercises | Hardware | CI |
+|---|---|---|---|
+| 0 | Pure Dart logic — cubits, services, signers, parsers | None | ✅ `flutter test --coverage` |
+| 1 | Cubit / widget + SDK-boundary fake — sign ceremonies via `FakeBitboxCredentials`; HTTP via `MockClient` | None | ✅ `flutter test --coverage` |
+| 2 | Real BitBox firmware-simulator over TCP (`bitbox_flutter` TCP transport) | Docker, no device | 🟡 Deferred — Phase 2 of #314 |
+| 3 | Maestro YAML flows on an iOS Simulator (handbook capture) · real BitBox02 hardware variant deferred | iPhone simulator (handbook) · iPhone + BitBox02 Nova (hardware) | 🟢 Handbook flows automated · 🟡 hardware variant deferred — Phase 3 of #314 |
+| 4 | BLE traffic capture / replay | Capture on hardware, replay anywhere | 🟡 Stretch — Phase 4 of #314 |
+
+## When to pick which tier
+
+```

+```
+
+If you can write a Tier 0 test, do that. Drop down only when a Tier 0 test would have to mock the very thing under test.
+
+## Tier 0 — pure Dart
+
+Test layout mirrors `lib/`. Stack: [`flutter_test`](https://pub.dev/packages/flutter_test), [`bloc_test`](https://pub.dev/packages/bloc_test), [`mocktail`](https://pub.dev/packages/mocktail) (NOT mockito), [`fake_async`](https://pub.dev/packages/fake_async) for time-bound assertions. Versions are pinned in `pubspec.yaml`.
+
+### Where things go under `test/`
+
+| Path | What goes here |
+|---|---|
+| `test/packages/**` | Pure-Dart services, signers, parsers, exceptions (mirrors `lib/packages/**`) |
+| `test/screens/<feature>/cubit(s)/**` and `test/screens/<feature>/bloc/**` | Cubit/Bloc state-transition specs (in the activated surface for line-coverage) |
+| `test/screens/<feature>/**/*_page_test.dart` | `testWidgets` view specs (cover the page, not the cubit logic) |
+| `test/integration/` | Cross-layer Tier-1 specs using `FakeBitboxCredentials` (e.g. `kyc_sign_flow_test.dart`) |
+| `test/helper/` | Shared test infra: [`pump_app.dart`](../test/helper/pump_app.dart), [`fake_bitbox_credentials.dart`](../test/helper/fake_bitbox_credentials.dart) |
+| `test/models/` | DTO / marshalling specs (`asset_test.dart`, `balance_test.dart`, `transaction_test.dart`, …) |
+| `test/setup/` | App lifecycle / bootstrap specs (`lifecycle_initializer_test.dart`) |
+| `test/styles/` | Currency / language fixtures (`currency_test.dart`, `language_test.dart`) |
+| `test/tool/` | Specs for the Dart scripts under `tool/` (`generate_release_info_test.dart`) |
+| `test/widgets/` | Shared widget specs that are not bound to one feature screen |
+
+### Cubit / Bloc
+
+Use `blocTest` from `bloc_test`. Mock the services it depends on with `mocktail.Mock`.
+
+```dart
+class _MockDfxKycService extends Mock implements DfxKycService {}
+class _MockRealUnitRegistrationService extends Mock implements RealUnitRegistrationService {}
+
+blocTest<KycCubit, KycState>(
+  'emits KycCompleted when level >= required and gates have passed',
+  setUp: () {
+    when(() => kycService.getKycStatus())
+        .thenAnswer((_) async => _kycStatus(level: KycLevel.level30));
+    when(() => kycService.getUser()).thenAnswer((_) async => _user());
+    // The cubit re-fetches the server-side registration info after the
+    // disclaimer gate and dispatches on its `state` field. Seed
+    // `AlreadyRegistered` to fall through to the `processStatus` dispatch
+    // below — the same path the production server walks for a returning
+    // shareholder.
+    when(() => registrationService.getRegistrationInfo()).thenAnswer(
+      (_) async => RealUnitRegistrationInfoDto(
+        state: RealUnitRegistrationState.alreadyRegistered,
+      ),
+    );
+  },
+  build: buildCubit,
+  act: (cubit) async {
+    cubit.markLegalDisclaimerAccepted();
+    await cubit.checkKyc();
+  },
+  expect: () => [const KycLoading(), const KycCompleted()],
+);
+```
+
+See `test/screens/kyc/cubits/kyc/kyc_cubit_test.dart` for the full set of state-transition cases.
+
+### Widget
+
+Use the project's [`pumpApp`](../test/helper/pump_app.dart) helper. Mock the cubits the widget reads from (`MockCubit<State>`) — do not exercise the cubit's logic here, that's a separate test.
+
+```dart
+class _MockKycEmailStepCubit extends MockCubit<KycEmailStepState>
+    implements KycEmailStepCubit {}
+
+testWidgets('shows SnackBar if submitting fails', (tester) async {
+  whenListen(
+    kycEmailStepCubit,
+    Stream.fromIterable([const KycEmailStepFailure('boom')]),
+    initialState: const KycEmailStepInitial(),
+  );
+
+  await tester.pumpApp(buildSubject(const KycEmailView()));
+  await tester.pump();
+
+  expect(find.byType(SnackBar), findsOneWidget);
+});
+```
+
+See `test/screens/kyc/steps/kyc_email_page_test.dart`.
+
+### Service + HTTP
+
+For services that hit the DFX API, swap in `MockClient` from [`http/testing`](https://pub.dev/packages/http) and a `_MockAppStore` that returns it via the `httpClient` getter.
+
+`DFXAuthService`-derived services walk `getAuthToken()` → `loadSignature()` → `getAuthResponse()` on a cold cache. Pre-seed the JWT in `setUp` so existing tests stay focused on wire behaviour:
+
+```dart
+setUp(() {
+  appStore = _MockAppStore();
+  sessionCache = SessionCache(_MockCacheRepository());
+  sessionCache.setAuthToken('test-jwt');                       // short-circuit refresh
+  when(() => appStore.sessionCache).thenReturn(sessionCache);
+  when(() => appStore.apiConfig)
+      .thenReturn(const ApiConfig(networkMode: NetworkMode.mainnet));
+});
+```
+
+See `test/packages/service/dfx/dfx_bank_account_service_test.dart`.
+
+### Mocktail gotchas
+
+- `Future<X>`-returning methods must use `thenAnswer((_) async => …)`, not `thenReturn`.
+- For matchers like `any()` over non-nullable custom types, register a fallback in `setUpAll`:
+
+  ```dart
+  setUpAll(() => registerFallbackValue(_registrationFixture));
+  ```
+
+- Test mocks should be private to the file (`class _MockX extends Mock implements X {}`). Don't leak them across files.
+
+### Constructor-fires-work cubits
+
+Some cubits kick off async work in their constructor (`SellBitboxCubit` calls `scheduleMicrotask(_checkEthBalance)`; `KycCubit` enters `checkKyc` via the page-level `BlocProvider(create: …)`). `blocTest`'s state-sequence assertion attaches a listener *after* the constructor runs, so it can miss the synchronous initial emit.
+
+Wait for the terminal state instead:
+
+```dart
+final cubit = build();
+final state = await cubit.stream.firstWhere((s) => s is SellBitboxEthReady);
+```
+
+This is also the pattern when you want to assert on the *final* state after a chain of internal emits (Loading → RequestingFaucet → WaitingForEth) without listing every transient step.
+
+### Widget tests that overflow the default viewport
+
+The default `tester` viewport is 800×600. Rows with multiple expanded children + long labels (`SellBitboxDepositStep`'s amount row, `LegalDisclaimerStep`'s text columns) report `RenderFlex overflowed by N pixels on the right/bottom`. Bump the viewport in the offending test:
+
+```dart
+tester.view.physicalSize = const Size(1200, 2400);
+tester.view.devicePixelRatio = 1.0;
+addTearDown(tester.view.resetPhysicalSize);
+```
+
+Don't change the production widget to compensate — the production layout is fine on real devices.
+
+### GoRouter harness for sheets that call `context.pop`
+
+`pumpApp` (via `MaterialApp.home`) does not provide a GoRouter, so any sheet that calls `context.pop(result)` throws "Null check operator used on a null value" on render. Use the `MaterialApp.router` constructor with a minimal route:
+
+```dart
+final router = GoRouter(
+  routes: [GoRoute(path: '/', builder: (_, _) => const MyBottomSheet())],
+);
+addTearDown(router.dispose);
+await tester.pumpWidget(MaterialApp.router(
+  routerConfig: router,
+  localizationsDelegates: [S.delegate, GlobalMaterialLocalizations.delegate],
+  supportedLocales: S.delegate.supportedLocales,
+));
+```
+
+`pumpApp` is fine for widgets that don't pop — only switch to the router harness when you need `context.pop` resolvable.
+
+### Shared test private key
+
+`FakeBitboxCredentials` derives its signatures from a single deterministic test private key. Reuse the same key directly when you need a real `EthPrivateKey` credential (for example to drive `Eip7702Signer.signAuthorization`, which rejects `BitboxCredentials`):
+
+```dart
+const _testPrivateKeyHex =
+    'fb1ace12f9801e85f3db1b3935dd47d9f064f98152466f47c701b5e12680e612';
+final privKey = EthPrivateKey.fromHex(_testPrivateKeyHex);
+// Derived address: 0x9F5713DEacB8e9CAB6c2d3FaE1AFc2715F8D2D71
+```
+
+Sharing the key lets cross-layer tests assert on a single recovered signer address — and means any envelope encoded by `FakeBitboxCredentials(success)` round-trips through `Eip712Signer.signRegistration` to the same byte sequence.
+
+### Service lifecycle (fake_async)
+
+Services with a `Timer`, an observer/subscription loop, or a platform/`MethodChannel` dependency must have a lifecycle test that instantiates the real class — never a mock of the service-under-test. Mocking the service hides timer leaks, unsubscribed listeners, and double-init bugs.
+
+Time-bound assertions must drive time via `package:fake_async`. Wall-clock `Future.delayed` is not acceptable: it makes tests slow and flaky.
+
+```dart
+import 'package:bitbox_flutter/bitbox_flutter.dart';
+import 'package:bitbox_flutter/testing.dart';
+import 'package:bitbox_flutter/usb/bitbox_usb_platform_interface.dart';
+import 'package:fake_async/fake_async.dart';
+
+late BitboxUsbPlatform previousPlatform;
+late SimulatedBitboxPlatform platform;
+
+setUp(() {
+  previousPlatform = BitboxUsbPlatform.instance;
+  platform = installSimulatedBitboxPlatform();
+});
+tearDown(() {
+  BitboxUsbPlatform.instance = previousPlatform;
+});
+
+// Pairing must run inside the fakeAsync zone so the periodic timer the
+// service installs is bound to the fake clock — otherwise `async.elapse`
+// will not pump it.
+BitboxService pairedServiceSync(FakeAsync async) {
+  final service = BitboxService(
+    connectionStatusInterval: const Duration(milliseconds: 50),
+  );
+  late List<BitboxDevice> devices;
+  service.getAllUsbDevices().then((d) => devices = d);
+  async.flushMicrotasks();
+  service.init(devices.single);
+  async.flushMicrotasks();
+  return service;
+}
+
+test('observer releases USB transport when device vanishes', () {
+  fakeAsync((async) {
+    final service = pairedServiceSync(async); // real instance, not a mock
+
+    platform.when(
+      SimulatedBitboxMethod.getDevices,
+      (_) async => const <BitboxDevice>[],
+    );
+    service.startConnectionStatusObserver();
+    async.elapse(const Duration(milliseconds: 150));
+
+    expect(
+      platform.count(SimulatedBitboxMethod.close),
+      greaterThanOrEqualTo(1),
+    );
+  });
+});
+```
+
+See `test/packages/hardware_wallet/bitbox_service_test.dart`. The rule is also documented in `CONTRIBUTING.md` ("Service-lifecycle tests are mandatory").
+
+### Exception surface
+
+Every typed exception in `lib/` (any class that `implements Exception` or `extends Exception`) must:
+
+1. Override `toString()` so the rendered string is non-empty and does not contain `Instance of '...'`.
+2. Be enumerated in `test/packages/service/dfx/exceptions/exception_surface_test.dart` in the same PR that introduces it.
+
+Exceptions surface in logs, Sentry, and user-facing error states — the Dart default `Instance of '...'` is useless for debugging and unfriendly for users. The surface test catches drift the moment a new exception is added without an enumeration entry.
+
+### Platform-coupled code without an integration test
+
+Platform-specific paths (USB transports, BLE lifecycle, secure storage, biometric prompts, deep links) must either ship a Tier 2/3 counterpart that exercises the real plugin (firmware simulator) or the real transport (Maestro on a device/simulator), or carry an inline `// @no-integration-test: <reason>` annotation. Today the simulator/Maestro counterpart is the long-term option but no `integration_test/` harness is wired up yet (see `CONTRIBUTING.md` footnote on the Tier-1 integration-test slot), so in practice the annotation is the documenting form on every new platform-coupled path. The annotation works at file level (as a dartdoc comment) or immediately above the function/method declaration. Grep current annotations with:
+
+```bash
+rg "^//\s*@no-integration-test:" lib/
+```
+
+As of today there are 0 annotations in `lib/` — the convention is in place but no platform-coupled path has needed it yet (the Tier 1 `test/integration/` specs cover the BitBox boundary via `FakeBitboxCredentials`, and the other platform surfaces above are not yet referenced from `lib/` in a way that would trip the rule). The block of files listed under "Surface that needs infra work" below is the practical near-term target.
+
+Unit tests with mocked platform channels cannot catch real-device regressions (permission prompts, OS-level lifecycle, transport quirks); the annotation makes the absence of an integration test a deliberate, reviewable decision rather than a silent gap.
+
+## Tier 1 — cubit / widget + SDK-boundary fake
+
+Tier 1 reuses the same `flutter_test` runner but swaps in [`FakeBitboxCredentials`](../test/helper/fake_bitbox_credentials.dart) at the BitBox boundary. The fake `is BitboxCredentials`, so every production type guard (e.g. the `BitboxNotConnectedException` check in `RealUnitRegistrationService`) treats it identically to a real device.
+
+`FakeBitboxBehavior` covers the five real-world ceremony outcomes:
+
+| Mode | Behaviour | Mirrors |
+|---|---|---|
+| `success` | Deterministic EIP-712 / personal-message signature from an embedded test private key | User confirms on device |
+| `cancel` | Returns `'0x'` | iOS bridge cancel signal |
+| `disconnect` | Throws `BitboxNotConnectedException`; `isConnected == false` | BLE link drop |
+| `timeout` | Never resolves; caller imposes its own outer timeout | Device hangs |
+| `malformed` | Returns non-hex data | Frame-desync regression (`bitbox_flutter` PR #11) |
+
+```dart
+test('cancel mid-sign: fake → Eip712Signer guard → SigningCancelledException', () async {
+  final fake = FakeBitboxCredentials(
+    behavior: FakeBitboxBehavior.cancel,
+    signDelay: Duration.zero,
+  );
+
+  await expectLater(
+    Eip712Signer.signRegistration(credentials: fake, /* … */),
+    throwsA(isA<SigningCancelledException>()),
+  );
+});
+```
+
+See `test/integration/kyc_sign_flow_test.dart` for cross-layer scenarios (happy path, cancel, disconnect, reconnect-and-retry).
+
+For the disconnect-flip-to-success retry pattern, mutate `fake.behavior` between calls:
+
+```dart
+fake.behavior = FakeBitboxBehavior.success;
+final retrySig = await fake.signTypedDataV4(1, payload);
+```
+
+### When to put a Tier 1 test under `test/integration/` vs `test/`
+
+- `test/integration/` — crosses ≥ 2 production layers AND uses the `FakeBitboxCredentials` boundary. Runs headless, no device. A behaviour change in any of the layers should break it.
+- `test/` — exercises a single layer with mocked dependencies.
+
+## Tier 2 — firmware simulator (deferred)
+
+The BitBox02 firmware simulator runs as a Docker container, speaks U2F-HID over TCP, and is pre-seeded with a fixed test mnemonic. Same Rust + C code path as the real device for every crypto operation, including the full 13-page EIP-712 sign.
+
+Status: deferred — Phase 2 of #314 has not landed yet. When it does:
+
+```bash
+docker compose up bitbox-simulator
+flutter run --dart-define=BITBOX_HOST=localhost:15423
+flutter test integration_test/ --dart-define=BITBOX_HOST=localhost:15423
+```
+
+Does **not** exercise iOS BLE — the simulator is USB-style framing only. Tier 3 stays the only validation for the BLE transport.
+
+## Tier 3 — Maestro flows
+
+YAML flows under `.maestro/` driven by [`maestro`](https://maestro.mobile.dev).
+
+Status: the handbook subset (`.maestro/handbook/*.yaml`) is automated on PRs labelled `tier3:full` and on every push to `develop` — see `.github/workflows/tier3-handbook.yaml`. The workflow resolves and boots an `iPhone 17` device on the highest available iOS 26 runtime; `scripts/run-handbook-flows.sh` then shuts the device down, `simctl erase`s it (Keychain wipes are the only reliable way to start on the welcome flow — see the script for the rationale), pins the simulator locale to `de_CH` so German handbook assertions pass on the `en_US`-default runner, reinstalls the debug `Runner.app`, and replays every flow back-to-back. Pixel-level drift detection for the page renders is **not** Tier 3's job — that is owned by the Visual-Regression golden suite (`flutter test test/goldens`, see [`visual-regression-tests.md`](visual-regression-tests.md)); Tier 3 catches the regressions Goldens cannot see — broken tap-routing, missing navigation, locale/`Intl` problems, iOS-build/install failures. The per-flow diagnostic captures land in `build/handbook-captures/` and are uploaded as the `handbook-captures` artifact for forensic inspection on assertion failure.
+
+The Maestro version is pinned in `.maestro-version` (today `2.0.10`).
+Maestro 2.3.x–2.5.x has documented intermittent failures on Apple
+Silicon + iOS 26.x — both driver-hang and silent tap-loss — tracked
+upstream as [mobile-dev-inc/maestro#3137](https://github.com/mobile-dev-inc/maestro/issues/3137).
+The pinned version is the workaround the upstream issue closed with.
+`scripts/run-handbook-flows.sh` retries the residual driver-hang
+class up to three times per flow as a safety net, and Tier 3 is
+opt-in via the `tier3:full` label rather than a required status
+check on `develop` (unlike `Analyze & Test`, `Visual Regression`,
+and `Coverage Floor Gate`, which are required — see ruleset `PRs`
+/ id `11317379`) until the reliability is proven on the pinned
+version over time. The CI-hardening track that landed this guard
+was [#487](https://github.com/DFXswiss/realunit-app/issues/487)
+(now closed).
+
+The real-hardware variant (BitBox02 Nova) stays deferred — Phase 3 of #314 — and is the entry point for any PR that adds a `bitbox:full` label later.
+
+## Tier 4 — VCR / replay (stretch)
+
+Capture iOS BLE traffic once on hardware, replay it deterministically thereafter. Status: stretch — Phase 4 of #314. Most of its value is covered by Tier 2 + Tier 3 in tandem.
+
+## CI
+
+Every PR runs Tier 0 and Tier 1 via the `RealUnit Build` workflow (`.github/workflows/pull-request.yaml`):
+
+```bash
+flutter pub get
+dart run tool/generate_localization.dart
+flutter pub run build_runner build
+flutter analyze
+flutter test --coverage
+```
+
+The workflow runs three jobs:
+
+- **`Analyze & Test`** — the block above, plus a `lcov --extract` step that narrows `coverage/lcov.info` to the activated surface (`lib/packages/**`, `lib/screens/**/cubit(s)/**`, `lib/screens/**/bloc/**`), followed by `lcov --remove '*.g.dart'` to strip generator output (Drift schema mirror) before summarising. The filtered tracefile (`coverage-lcov`) and a one-line summary (`coverage-summary`) are uploaded as artifacts.
+- **`Coverage Floor Gate`** — downloads `coverage-summary` and fails the build when scoped line/function coverage drops below the integers committed to `.coverage-floor-lines` and `.coverage-floor-functions`. Required status check on `develop` + `main` (ruleset `PRs` / id `11317379`) alongside `Analyze & Test` and `Visual Regression` — a coverage regression blocks the merge. Ratchet protocol is documented in `README.md`.
+- **`BitBox quirks audit`** — runs `bitbox-audit` against the diff and inlines its report into the workflow run summary; uploaded as `bitbox-audit-report`.
+
+Tier 3 runs separately under `tier3-handbook.yaml` (push to `develop`, manual, or any PR labelled `tier3:full` except PRs targeting `main`). Its only artifact is `handbook-captures`, the per-flow diagnostic recordings — coverage data is owned by `Analyze & Test` instead.
+
+The Tier 0/1 coverage artifacts (`coverage-lcov`, `coverage-summary`) are emitted by the `Analyze & Test` job in `pull-request.yaml` (see [#323](https://github.com/DFXswiss/realunit-app/pull/323)) and consumed by the `Coverage Floor Gate`. The repo holds a [100 % coverage rule](https://github.com/DFXswiss/realunit-app/pull/322) for new code on the activated surface; the committed floor lives in `.coverage-floor-lines` and `.coverage-floor-functions` and is ratcheted upward per PR — drop the threshold only with reviewer sign-off and a written reason (`coverage:lower-floor` label).
+
+## Surface that needs infra work before it can be unit-tested
+
+Some files are deliberately uncovered today because exercising them would change project architecture, not just add a test. Don't waste time stubbing around these without a focused infra PR first:
+
+| Area | Why it's not unit-tested | What it would take |
+|---|---|---|
+| `lib/screens/*/`-Page widgets that call `getIt<X>()` directly (Dashboard, Receive, Settings sub-pages) | Service locator usage inside `build` makes the cubits the page wires up impossible to swap | Move the `BlocProvider(create: (_) => Cubit(getIt<X>()))` lookup up one layer so tests can `BlocProvider.value` a mock |
+| `lib/widgets/chain_asset_icon.dart`, `lib/widgets/image_picker_sheet.dart` | `Image.asset` / `ImagePicker` need a real asset bundle / platform channel | Mock the asset loader / use the platform-interface fake |
+
+Drift-backed repositories under `lib/packages/repository/*` are fully covered: `AppDatabase.forTesting` (`lib/packages/storage/database.dart`) accepts `NativeDatabase.memory()`, and `test/packages/repository/{asset,balance,cache,transaction,wallet}_repository_test.dart` exercise every wrapper. The SharedPreferences-backed `SettingsRepository` and the service-backed `SupportedFiat`/`SupportedLanguage` repositories have specs alongside them too.
+
+The Sumsub `flutter_idensic_mobile_sdk_plugin` boundary previously listed here is now abstracted via `SumsubIdentPort` (interface under `lib/screens/kyc/steps/ident/cubits/kyc_ident/sumsub_ident_port.dart`, real implementation `SumsubIdentSdkAdapter` outside the cubit folder). The cubit takes the port via constructor injection and is covered by `test/screens/kyc/steps/ident/cubits/kyc_ident/kyc_ident_cubit_test.dart` with an inline `_FakeSumsubIdentPort`. The SDK adapter itself carries the `@no-integration-test` annotation and is intentionally outside the cubit coverage scope.
+
+The `getApplicationDocumentsDirectory()` / `getTemporaryDirectory()` boundary that used to block `transaction_history_*receipt_cubit` and `settings_tax_report_cubit` is now abstracted via `DocumentsDirectoryPort` (interface under `lib/packages/io/documents_directory_port.dart`, real implementation `PathProviderAdapter`). The cubits take the port via constructor injection with a `const PathProviderAdapter()` default. The adapter forwarders carry a block-level `coverage:ignore` + `@no-integration-test` annotation because they are 1:1 wrappers around the platform channel the port abstracts. The same port is also used by `AppDatabase.getDatabasePath()`.
+
+When you find yourself wanting to test one of these, do the infra PR first and document the new injection point in this file.
+
+## Adding tests when you touch BitBox-related code
+
+PRs touching `KycCubit`, `KycRegistrationSubmitCubit`, `Eip712Signer`, `DFXAuthService`, `BitboxCredentials`, or `bitbox_flutter` must add Tier 0 (and ideally Tier 1) coverage. The pattern that gets BitBox bugs caught early:
+
+1. Identify the new behaviour as either a logic branch (Tier 0) or a multi-layer interaction (Tier 1).
+2. If Tier 1: pick the `FakeBitboxBehavior` that exercises it. If none fits, extend the enum.
+3. Assert the typed result (`SigningCancelledException`, specific `KycState`, specific `RegistrationStatus`) — never on a stringified message.

+# Visual Regression Tests
+
+Pixel-exact baseline tests for every page in the app. 57 `lib/screens/**/*_page.dart`
+files mapped to 94 Golden PNGs under `test/goldens/screens/` (page renderings
+plus state variants: Buy/Sell error banners, KYC loading/failure, Dashboard
+with-balance, RestoreWallet valid/invalid, Legal-Disclaimer steps, etc.),
+validated on each PR by the `Visual Regression` job (required status check
+on `develop` + `main`).
+
+## Stack
+
+| Component | Choice |
+|---|---|
+| Framework | [alchemist](https://pub.dev/packages/alchemist) 0.14.0 (Betterment) |
+| Font | Open Sans, eingecheckt unter `assets/fonts/` (SIL OFL 1.1) |
+| Render host | dfx01 self-hosted runner (Mac Studio M3 Ultra) — Labels `self-hosted, macOS, ARM64, m3-ultra, realunit-app` |
+| Theme | `realUnitTheme` (light) aus `lib/styles/themes.dart` |
+| CI job | `golden-tests` in `.github/workflows/pull-request.yaml` |
+
+Baselines werden ausschliesslich auf dfx01 generiert und validiert. Lokales
+`flutter test test/goldens/` schlägt erwartet mit Pixel-Drift fehl
+(unterschiedliche Mac-Hardware/macOS-Versionen rendern Sub-Pixel-AA leicht
+anders).
+
+## Layout
+
+One test file per `lib/screens/<feature>/<feature>_page.dart` under
+`test/goldens/screens/<feature>/<feature>_golden_test.dart`. Some pages
+have multiple state variants (e.g. Welcome has iOS + Android theme,
+Buy has initial + payment-info-loaded, Settings has default +
+confirm-logout-sheet) — those produce more than one PNG each. All
+baselines live under `test/goldens/screens/<feature>/goldens/macos/*.png`.
+
+### Skipped: `web_view_page.dart`
+
+The one `skip: true` in the suite. `InAppWebView` from `flutter_inappwebview` is a platform-view, not a regular widget — its rendering happens via the iOS/Android view-embedding API and has no headless representation in `flutter_test`.
+
+Method-channel stubbing alone is **not enough**: the widget's first build asserts that `InAppWebViewPlatform.instance` is set, and that interface declares five abstract `createPlatform…` methods (controller, widget, cookie manager, etc.) — each returning another platform-view-bound class. A working stub would need ~50 lines of mock subclasses and would still render the body as a blank rectangle.
+
+For a one-page edge case the cost/benefit doesn't justify it. The test is committed with `skip: true` and reactivates the moment someone wires up a full `InAppWebViewPlatform` mock — preferably published as a separate test-only package so other Flutter apps can reuse it.
+
+## Regenerating baselines
+
+Permanent on-demand workflow `.github/workflows/golden-regenerate.yaml`
+runs `flutter test test/goldens --update-goldens` on dfx01 and commits
+the regenerated PNGs back to the dispatched branch as
+`github-actions[bot]`. One command:
+
+```bash
+gh workflow run golden-regenerate.yaml --ref <feature-branch>
+```
+
+When the run finishes green, the new baselines are already on the
+branch — pull and continue. No download / rsync / manual commit step.
+
+The workflow is `workflow_dispatch`-only, runs on the same
+`[self-hosted, macOS, ARM64, m3-ultra, realunit-app]` labels as
+`golden-tests`, and uses concurrency `golden-regenerate-<ref>` so two
+back-to-back dispatches on the same branch don't race each other.
+
+**Gotcha — bot push does not trigger PR-CI.** GitHub Actions
+deliberately suppresses workflow runs for pushes made by the default
+`GITHUB_TOKEN` (the credential the bot uses), to avoid recursion loops.
+Consequence: after the bot lands the regenerated baselines, the latest
+SHA on the PR has **zero status checks** and `mergeStateStatus` flips
+to `CLEAN` because no required checks remain to wait for — even though
+`Analyze & Test` / `Visual Regression` / `Coverage Floor Gate` never
+ran against the new baselines. To re-arm the CI, push an empty commit
+signed by your own user:
+
+```bash
+git commit --allow-empty -m "ci: trigger workflows on bot regen"
+git push
+```
+
+The required checks now run against the bot's baselines for real.
+Without this step the merge button is misleading.
+
+On a protected ref (`develop`, `main`) the push fails by design — no
+force-push, no bypass. The same artifact-fallback also kicks in if a
+parallel human push raced the bot (non-fast-forward); the workflow
+does not retry-rebase. In either case the regenerated PNGs are uploaded
+as the `golden-baselines` artifact; download and rsync them onto a
+feature branch:
+
+```bash
+RUN_ID=$(gh run list --workflow=golden-regenerate.yaml --limit 1 --json databaseId --jq '.[0].databaseId')
+gh run download "$RUN_ID" -n golden-baselines -D /tmp/baselines
+rsync -a /tmp/baselines/ test/goldens/
+git add test/goldens/
+git commit -m "test(goldens): regenerate baselines on dfx01"
+git push
+```
+
+## Day-to-day workflow
+
+### Adding a new golden test
+
+1. Add a `*_golden_test.dart` under `test/goldens/screens/<feature>/`.
+   Reuse the mock pattern from the existing golden tests.
+2. Open a Draft PR. The `golden-tests` job will be red because the new
+   test has no committed baseline.
+3. Run `gh workflow run golden-regenerate.yaml --ref <branch>`. The
+   workflow regenerates on dfx01 and pushes the PNGs back to the
+   branch as `github-actions[bot]`. Pull and verify `golden-tests`
+   goes green.
+
+### Reacting to a CI drift
+
+CI shows the `Run visual regression tests` step red and an artifact
+`golden-diffs` is uploaded. Open the artifact and inspect the diff PNG:
+
+* **Intentional change** (you redesigned the UI): regenerate baselines via
+  `gh workflow run golden-regenerate.yaml --ref <branch>` (see
+  "Regenerating baselines" above) and let the bot commit the new PNGs
+  onto the branch.
+* **Regression** (UI shouldn't have moved): fix the code; CI returns to
+  green when pixels match again.
+
+Never silently re-record baselines to make CI green — review the diff
+visually first.
+
+### Flutter SDK bumps
+
+A Flutter bump (`flutter-version` in `.github/workflows/*.yaml`) changes
+Skia's text shaper or layout subtly. Goldens become stale. On the bump
+branch, dispatch the regenerate workflow:
+
+```bash
+gh workflow run golden-regenerate.yaml --ref <bump-branch>
+```
+
+The bot pushes `test(goldens): regenerate baselines on dfx01` onto the
+branch; rename or amend the commit message locally if a more specific
+"regenerate after Flutter X.Y.Z bump" note is useful.
+
+### dfx01 outage fallback
+
+If dfx01 is down (power, macOS update, service maintenance) and a PR is
+blocked on `golden-tests`:
+
+1. Switch `runs-on:` in `pull-request.yaml` for the `golden-tests` job —
+   and in `golden-regenerate.yaml` — from `[self-hosted, ..., realunit-app]`
+   to `macos-15`.
+2. Dispatch the regenerate workflow on the branch to refresh all baselines
+   on `macos-15`.
+3. Merge. When dfx01 is back up, flip `runs-on:` back in both workflows
+   and regenerate baselines on dfx01 in a separate PR.
+
+This path is intentionally manual — it's a notfall, not a routine. The
+flipping of baselines between two hosts incurs a mass-PNG-change PR each
+direction.
+
+### macOS update on dfx01
+
+The Mac Studio M3 Ultra runs macOS — updates change Skia/CoreText
+versions slightly. Before applying a macOS update on dfx01:
+
+1. Prepare a regenerate-baselines PR.
+2. Apply the macOS update.
+3. Run the regenerate workflow, commit, push, merge.
+
+## Architecture notes
+
+### Why `realunit-app` not `realunit-ios` as runner label?
+
+The label registered in `DFXswiss/realunit-app` is `realunit-app`, not the
+`realunit-ios` documented in `DFXServer/server` for the earlier Tier 3
+Maestro plan. Goldens are headless Skia (no iOS Simulator), so an
+`-ios`-suffixed label would be misleading. If the runner later picks up
+Tier 3 Maestro work too (e.g. when the dfx01 capacity allows it), add the
+`realunit-ios` label alongside the existing one — single runner, two
+workload classes.
+
+### Why pin Open Sans as an asset?
+
+`lib/styles/text_styles.dart:4` declares `fontFamily: 'Open Sans'` but
+the font was never an asset — Flutter fell back to the system font at
+runtime. That fallback is not deterministic across macOS hosts. Goldens
+require pixel-stable text rendering; the only honest fix is to ship the
+font with the app. The 5 TTF variants (Regular, Italic, SemiBold, Bold,
+BoldItalic) live under `assets/fonts/` with the SIL OFL 1.1 license file.
+
+### Why dfx01 not GitHub-hosted macos-15?
+
+Performance (M3 Ultra ~2-3× faster than the GitHub macOS hosted runner)
+and Hardware-Determinismus (identical Skia/CoreText/HW across runs —
+no GitHub image bump can drift the baselines). The cost argument does
+**not** apply — `DFXswiss/realunit-app` is public, GitHub Actions on
+public repos are free even for macOS minutes.
+
+## Handbook screenshots are sourced from Goldens
+
+The 52 PNGs the handbook serves at `handbook.realunit.app/screenshots/`
+are assembled from the Golden baselines at docker-build time. One
+Golden → one handbook page, via the explicit mapping in
+`scripts/assemble-handbook-screenshots.sh`. The handbook does **not**
+have its own screenshot set anymore.
+
+### Why
+
+- **Single source of truth.** A UI regression that flips a Golden also
+  breaks the handbook image before either ships. The pixel-checked
+  baseline IS the documentation.
+- **Determinism.** dfx01's headless Skia/Open Sans render is byte-stable
+  across CI runs. The previous Maestro-driven iOS-Simulator capture
+  drifted on Apple Silicon + iOS 26 driver hangs
+  (mobile-dev-inc/maestro#3137).
+- **Cycle time.** The handbook image rebuilds when Goldens change in
+  seconds. No 30-minute Maestro suite to refresh a page.
+
+### Where each handbook page comes from
+
+Authoritative mapping table lives in
+`scripts/assemble-handbook-screenshots.sh` — keep it in sync with
+`.maestro/handbook/*.yaml` (one entry per flow). The script copies the
+Golden into the output directory with the handbook's expected
+`NN-name.png` filename; the Dockerfile multi-stage build then layers
+that directory into `/usr/share/nginx/html/screenshots/`.
+
+### When you add a new handbook page
+
+1. Add the `.maestro/handbook/<NN>-<name>.yaml` flow (still useful as
+   integration smoke even if no longer the screenshot source — see
+   Maestro section below for current PR-gate vs nightly status).
+2. Add a Golden test under `test/goldens/screens/<screen>/` that
+   renders the same UI state as the handbook flow's terminal screen.
+3. Add a row to the `MAPPING` array in
+   `scripts/assemble-handbook-screenshots.sh` pointing at the new
+   Golden file.
+4. Open the PR. The `Handbook Build Check` workflow runs
+   `docker build` and a container smoke (`/healthz` + auth gate +
+   probe `/screenshots/<NN>-*.png`). A missing Golden surfaces here
+   as a missing-source error from the assembly script before docker
+   even spins up.
+
+### When you change an existing handbook page
+
+Touch the Golden test (or the underlying widget/copy), let CI regenerate
+the baseline on dfx01, and commit the new PNG. The handbook picks up
+the change automatically on the next docker build — no separate
+handbook-screenshot recapture step needed.
+
+### Reviewing a handbook visual change
+
+Pull the artifact or diff the PNG in `test/goldens/screens/**/` like
+any other Golden review. There is no second set of handbook PNGs to
+also check.

+# Wallet Modes
+
+The realunit-app supports three wallet modes. Two are real user-facing options
+(software and BitBox); the third (`debug`) is a developer-only address +
+signature mode used to inspect a known wallet without holding its key
+material. Each mode has a different signing capability, and any feature that
+needs an EIP-712 signature must be gated on that capability before the user
+is sent into the flow.
+
+The enum lives at `lib/packages/wallet/wallet.dart`:
+
+```dart
+enum WalletType { software, bitbox, debug }
+```
+
+## Modes at a glance
+
+| Mode | Holds key material? | EIP-712 signing | Typical user flow |
+|---|---|---|---|
+| `software` | yes (12-word seed, encrypted at rest) | signs in the background, near-zero user friction | full app — register, link wallet, trade |
+| `bitbox` | yes (on the hardware device) | requires confirmation on the connected unlocked BitBox | full app — register, link wallet, trade |
+| `debug` | no (address only, plus a stored signature attestation) | **cannot sign** — `DebugWalletAccount.signMessage` throws `UnsupportedError` | read-only browsing of a known address, plus any flow that the API accepts without a fresh signature (`AlreadyRegistered`, `KycRequired`) |
+
+## Features that require signing
+
+The RealUnit registration flow signs an EIP-712 envelope so the backend can
+prove the user owns the wallet. Two API-driven sub-flows reach the signer:
+
+- `RealUnitRegistrationState.newRegistration` — full registration form,
+  `KycRegistrationPage`
+- `RealUnitRegistrationState.addWallet` — one-tap "Add this wallet" page,
+  `KycLinkWalletPage`
+
+Both are gated in `KycCubit._runCheckKyc` directly after the
+`RealUnitRegistrationService.getRegistrationInfo()` round-trip. When the
+current wallet is `WalletType.debug` and the API has routed to either of the
+above states, the cubit emits `KycSignatureUnsupportedFailure` instead of
+`KycSuccess`, and `KycPageManager` renders `KycSignatureUnsupportedPage`.
+
+`AlreadyRegistered` and `KycRequired` do not invoke the signer, so debug-mode
+users flow through them unchanged.
+
+## Why this gate is local
+
+Signing capability is a physical property of the wallet implementation —
+nothing the server returns can change whether the user's device can produce
+an EIP-712 signature. This is the same exception class as the PIN / wallet
+lock / BitBox connection gates listed in CONTRIBUTING.md's
+*"API as Decision Authority"* rule under "physical security boundary". The
+gate is intentionally local; it does not duplicate any API decision.
+
+## Future: feature gating
+
+Any future feature that needs an EIP-712 signature (or any wallet-side
+cryptographic operation the debug mode cannot service) should follow the
+same pattern:
+
+1. Read `getIt<AppStore>().wallet.walletType` at the routing decision point
+   (a cubit, never a widget).
+2. Emit a dedicated terminal failure state (parallel to
+   `KycSignatureUnsupportedFailure`).
+3. Render a tailored page in the feature's page-manager switch.
+
+Do not let the sign call blow up deep inside the flow with a raw
+`UnsupportedError` — the UX must be deterministic and explain to the user
+which modes are supported.

+"""Generate the handbook legal-downloads block from the in-app legal Markdown.
+
+The Markdown under assets/legal/ is the single source of truth for the three
+RealUnit documents that the app renders in-app (LegalDocumentPage reads
+assets/legal/<base>_<lang>.md via rootBundle). The handbook section at
+handbook.realunit.app is a *derived export* of those files — never hand-edited.
+This mirrors the upstream/downstream relationship that the store-listing and
+mails/ sections already have.
+
+Usage:
+    scripts/assemble-handbook-legal.py <output-dir>
+
+Used by:
+  - Dockerfile.handbook (legal-docs-builder stage → rewrites docs/handbook/de/
+    index.html; the PDF/DOCX binaries are produced separately by
+    scripts/build-legal-downloads.sh — see the determinism note below)
+  - .github/workflows/handbook-build-check.yaml (sync gate: re-run + git diff)
+  - local previews (run it, then open docs/handbook/de/index.html)
+
+What it does:
+  1. Discovers the document set: for each base in BASES, globs
+     assets/legal/<base>_*.md to find the available languages. Errors out if a
+     base has zero languages.
+  2. Resolves each document's title from assets/languages/strings_<lang>.arb
+     (the mapped ARB key per base, see TITLE_KEYS) so the handbook titles stay
+     in lockstep with the in-app titles. Falls back to the `de` title if a
+     language's ARB lacks the key.
+  3. Renders scripts/templates/legal-downloads.html.tmpl into
+     <out>/legal-downloads.html and substitutes the rendered block between the
+     <!-- BEGIN:legal-downloads --> / <!-- END:legal-downloads --> markers in
+     docs/handbook/de/index.html in place (idempotent).
+
+What it deliberately does NOT do:
+  - It does NOT invoke pandoc and does NOT emit any PDF/DOCX. Those binaries are
+    non-deterministic (embedded timestamps, tool-version metadata) and are
+    produced only inside the image by scripts/build-legal-downloads.sh, git-
+    ignored like the screenshots. Keeping pandoc out of this script is what lets
+    the rendered HTML block be deterministic and therefore sync-gateable.
+
+  Every value interpolated into the HTML (titles from ARB, discovered language
+  codes) is HTML-escaped; the document bases are a fixed allowlist (BASES).

+Store Connect / Play Console. The handbook section at handbook.realunit.app is

+  2. Reads the metadata .txt files. All text fields are HTML-escaped except
+     the Android long description, which Google Play renders as a small HTML

+     sanitizer — before it is interpolated unescaped into the page.
+  3. Renders scripts/templates/store-listing.html.tmpl into
+     <out>/store-listing.html (single-pass placeholder substitution).
+  4. Substitutes the rendered block between the
+     <!-- BEGIN:store-listing --> / <!-- END:store-listing --> markers in

+#
+# Tier-3 navigation smoke for the 26 .maestro/handbook/*.yaml flows.
+#
+# For each flow (alphabetical order):
+#   1. run the Maestro flow — navigates the real built app to the target
+#      screen and asserts the expected UI state is reachable
+#   2. take a diagnostic screenshot via `xcrun simctl io booted screenshot`,
+#      written to build/handbook-captures/ so CI can attach it as an
+#      artifact for forensic inspection on assertion failures
+#
+# NOT the source of `handbook.realunit.app` screenshots — those are the
+# visual-regression Golden baselines under test/goldens/screens/, mapped
+# by scripts/assemble-handbook-screenshots.sh. See docs/handbook/README.md.
+#
+# Why xcrun rather than Maestro's built-in `takeScreenshot`?
+#   Maestro screenshots go through XCUITest, which renders the view-hierarchy
+#   bitmap. Flutter screens that use `BackdropFilter` (e.g. SeedBlurCard on
+#   the seed-backup pages) live on a GPU layer outside that bitmap and come
+#   out as solid black PNGs. `xcrun simctl io booted screenshot` uses the
+#   simulator's compositor and captures the actual final frame.
+#
+# Required:
+#   * iOS Simulator booted with Runner.app installed (`flutter build ios
+#     --simulator --debug` then `xcrun simctl install booted ...Runner.app`)
+#   * maestro CLI on PATH (or at $HOME/.maestro/bin/maestro)
+#
+# Locale:
+#   The booted simulator's locale is pinned to de_CH because the handbook
+#   flows assert on German UI strings (e.g. "Digitale Wallet", "Erstellen
+#   Sie Ihre PIN", "Einstellungen"). Local devs running this script will
+#   have their simulator locale temporarily overridden; `simctl erase` on
+#   the next run brings it back to defaults. CI runners default to en_US
+#   without this pin and would fail the first German-string assertion.
+#
+# Retry strategy:
+#   The Maestro version is pinned by `.maestro-version` (read by the
+#   workflow's install step). Historically Maestro 2.3.x–2.5.x had
+#   intermittent driver-hang AND silent-tap-loss issues on Apple
+#   Silicon + iOS 26.x (see mobile-dev-inc/maestro#3137); the pin
+#   targets a known-good release. The retry remains as a safety net
+#   for residual Apple-XCTest crashes (~10 % per the #3137 thread):
+#   each flow is retried up to MAESTRO_MAX_ATTEMPTS times (default 3)
+#   when the failure log contains `IOSDriverTimeoutException`.
+#   Assertion failures are NEVER retried — those are real regressions
+#   and must surface as red CI checks.
+#
+# Usage:
+#   scripts/run-handbook-flows.sh                    # run ALL handbook flows
+#   scripts/run-handbook-flows.sh 25-restore-wallet  # run only matching flows
+#   scripts/run-handbook-flows.sh '2*' 12-settings   # multiple glob patterns
+#
+#   With no arguments every flow in .maestro/handbook/*.yaml runs (the
+#   default, full-suite behaviour). With one or more positional arguments,
+#   each argument is a bash glob pattern matched against the flow basename
+#   (filename without the `.yaml` extension); only flows whose basename
+#   matches AT LEAST ONE pattern are run, in the same deterministic sorted
+#   order. If arguments are given but match zero flows the script exits 1.
+#
+# WARNING — handbook flows are a sequential CHAIN sharing app state:
+#   The numbered flows are designed to run in order, each one continuing
+#   from the app state the previous flow left behind. Running a mid-chain
+#   flow in isolation will fail because it expects state set up by the
+#   flows before it. Only flows that begin with their own `launchApp`
+#   re-establish a known starting point and are therefore safe to run
+#   alone — every other flow must be run together with its predecessors.

+// and the user re-plugs to retry:
+//
+//   1. FakeBitboxCredentials — flips behaviour mid-flight so a single
+//      credentials instance can simulate success → disconnect → success on
+//      a retry, the same arc the real BitBox plugin exposes via mid-sign
+//      BLE link drops.

+//   2. BitboxService observer — periodically probes the simulator-backed
+//      platform interface for present devices and clears every active
+//      `BitboxCredentials` in place when the device list goes empty. The
+//      observer must NOT null the credentials reference (a follow-up
+//      `init()` re-attaches the manager via `setBitbox`).
+//
+//   3. SellBitboxCubit.retryAfterConnection — the cubit-side recovery hook
+//      the screen calls after the BitBox-required gate flips back to
+//      connected. The cubit re-checks `credentials.isConnected` and emits
+//      `SellBitboxEthReady` (or the faucet/error branch) accordingly.
+//
+// Tests run inside `fakeAsync` so the observer's periodic timer and the
+// cubit's microtask-based `_checkEthBalance` are both bound to the same
+// virtual clock — no wallclock-sleeps, deterministic tick counting.

+// dedicated suites, and a regression in those layers must not surface as

+// These tests stitch the WalletService together with a *real* BitboxService
+// driven by the official bitbox_flutter simulator, a *real* WalletRepository
+// backed by a Drift in-memory database (AppDatabase.forTesting +
+// NativeDatabase.memory), and a *real* SettingsRepository on

+//
+//   WalletService.createBitboxWallet
+//     → BitboxService.bitboxManager.getETHAddress  (via the simulator)
+//     → WalletRepository.createViewWallet          (writes walletInfos)
+//     → SettingsRepository.saveCurrentWalletId     (persists current id)
+//
+// Style anchors:
+//   * test/integration/connect_bitbox_flow_test.dart (simulator install +
+//     tearDown pattern)
+//   * test/packages/repository/wallet_repository_test.dart (in-memory DB +
+//     mock SecureStorage setup)
+//   * test/packages/service/wallet_service_test.dart (the createBitboxWallet
+//     contract — pinned here against the *real* downstream stack instead of
