The observer keeps thinking we are connected; the next + reconnect must come from the user manually unplugging. +- F-045 — `_connectionStatusObserver` only inspects the `devices.isEmpty` branch + and ignores any non-empty list. A user who unplugs their BitBox and plugs in a + different one is reported "still connected". +- F-005 / F-024 — `_credentialsByAddress` is never cleared on wallet-delete; + `_onDeleteCurrentWallet` only stops the observer. A subsequent "restore from + different seed → pair same physical device at a different account index" + silently re-attaches the OLD derivation path. +- F-007 — `init()` is not serialised against concurrent invocation; two + rapid-fire `connectToBitbox` calls can race two `bitboxManager.connect()` calls + on the same manager, with undefined behaviour for the noise channel. +- F-033 / F-034 — no `dispose()` on the singleton; hot-restart leaves the + prior `BitboxManager` claimed natively. + +The worst case is: user deletes wallet A, factory-resets the BitBox, restores +wallet B from a different seed. Stale credentials bind wallet B's derivation +path to the device's new static pubkey without prompting re-pair; the observer +reports "still connected"; the next sign flows to a device the user no longer +owns. + +## Decision + +Adopt a single source of truth for the BitBox connection state, owned by +`BitboxService`.

Equality is value-based (Equatable). The stream is +broadcast and replay-last-value — late subscribers receive the current state +synchronously on subscription. + +### Ownership rules + +- `BitboxService` is the **sole writer** to the stream. +- `BitboxCredentials` does NOT mutate `BitboxService` state directly. When + `_synchronizeBoundedSign` hits a timeout it calls + `_bitboxService.signalDeviceLost(LostReason.signQueueTimeout)` and lets the + service decide the transition. +- `ConnectBitboxCubit` does NOT keep its own `isConnected` field. Its state is + derived from the stream + its own UX-only states + (`BitboxCheckHash`, `BitboxCapturingSignature`, etc.). The pairing flow is + still cubit-driven; the new contract is that whenever the cubit needs to + know "are we still connected?", it asks `BitboxService.currentStatus`. +- `HomeBloc._onDeleteCurrentWallet` calls `BitboxService.clear()` — which + empties the credentials map, tears down the observer, disconnects, and + emits `Disconnected` — in addition to the existing + `stopConnectionStatusObserver` (kept for backward compatibility; `clear()` + invokes it internally). +- `WalletService` does not subscribe — it consumes `BitboxService` only + through explicit method calls. The lifecycle hook is the `clear()` call + on wallet delete (mediated by `HomeBloc`). +- Stream subscriptions in cubits are mandatory-cancelled in `close()`. + +### Init concurrency guard + +`init()` is guarded by a `Future? _pendingInit`. +Concurrent callers `await` the same future. Result: + +- One physical `bitboxManager.connect(device)` per concurrent batch. +- Property-test pinned: for any N concurrent `init()` calls, exactly one + `connect()` invocation. + +### Lifecycle methods + +- `Future init(BitboxDevice)` — guarded; emits + `Connecting(device)` then `Paired(device)` on success, `Disconnected` on + failure. +- `Future clear()` — disconnects, cancels observer, empties + `_credentialsByAddress`, emits `Disconnecting → Disconnected`. Idempotent. +- `void signalDeviceLost(LostReason)` — only valid from `Paired` / `InUse`; + emits `Lost(reason)`, tears down observer, clears each credentials' manager. + Idempotent — repeated calls from the same state are no-ops. +- `Future dispose()` — emits final `Disconnected`, closes the stream + controller. Used for hot-restart and end-of-app. Post-`dispose()` calls to + `init()` throw `StateError`. + +## Alternatives considered + +1. **Enum instead of sealed class.** Rejected. The `Paired(device)` and + `Lost(reason)` variants carry data that consumers need (which physical + device is paired, why the device was lost). An enum would force a separate + "current device" field on the service, recreating the parallel-state-of-truth + problem. + +2. **`ValueNotifier` instead of `Stream`.** Rejected. + `ValueNotifier` is a Flutter framework type and would couple `BitboxService` + (a service-layer construct, tested without `flutter_test`) to widget tree + lifecycles. A `Stream` carries no framework dependency, integrates with + `bloc`'s `emit`/`listen` patterns, and supports backpressure semantics if + we ever need them. + +3. **Plain `StreamController.broadcast()` without + replay.** Rejected. Late subscribers (e.g. a fresh `ConnectBitboxCubit` after + the service has already paired) would not see the current state until the + next transition. The Stream-with-replay-last-value pattern (hand-rolled + inside `BitboxService` via a `_lastStatus` field exposed as `currentStatus` + + an immediate replay in the stream getter) preserves the "subscribe and + know" property without dragging in `rxdart`'s `BehaviorSubject`. `rxdart` + is not in `pubspec.yaml` today; adding it just for one type would violate + Mandate §1 Law 15. + +4. **Per-credentials connection state instead of service-level.** Rejected. + The audit (F-005, F-024) shows that any per-instance flag desyncs from + the physical-device truth and from sibling credentials sharing the same + noise cipher. Single SoT at the service is the only invariant that + survives the multi-credential-fan-out lifecycle. + +5. **No replay at all; consumers cache the latest state themselves.** + Rejected — it reintroduces the parallel-state-of-truth problem this ADR + exists to solve. + +## Consequences + +### Positive + +- Single source of truth for connect-state — F-005, F-007, F-009, F-024, + F-032, F-033, F-034, F-045 close as one architectural unit. +- Property-pinnable invariant: any sequence of `init`/`clear`/`signalDeviceLost` + emits a valid state-machine traversal. +- Sign-queue timeout no longer silently desyncs the service from the + credentials. +- `_onDeleteCurrentWallet` cleanup actually clears the credentials map — + closes the "delete wallet, restore different seed, sign against wrong + derivation path" worst-case in the Context section. +- Stream model integrates cleanly with the `bloc` package and with future + Initiative III FakeBitboxCredentials inject-points + (`injectDisconnectAtPage`, etc.). +- `dispose()` makes hot-restart and tests deterministic. + +### Negative + +- The pre-existing `bool isConnected` on `BitboxCredentials` becomes a derived + view, not a writeable flag. Tests that asserted on it still work but should + be migrated to assert on `service.currentStatus` for clarity. Migration in + Initiative I commits. +- Every consuming cubit gains a stream subscription that must be cancelled + in `close()`. Lint-enforceable if we add the lint; in the interim, the + cubit close path is asserted by unit test. + +### Neutral + +- The pre-existing `startConnectionStatusObserver()` / `stopConnectionStatusObserver()` + callers (`ConnectBitboxCubit`, `HomeBloc`) keep their direct API for now; + the observer is an internal driver of the stream rather than a parallel + signal.

The `_isConnected` boolean is removed; consumers subscribe to `status` or read `currentStatus` instead. `init()` is guarded by `_pendingInit` so concurrent callers funnel onto a single bitboxManager.connect(). New lifecycle methods land here as a coherent unit: - `init(BitboxDevice) -> Future` — guarded by `_pendingInit`; emits `Connecting -> Paired` on success or `Connecting -> Disconnected` on failure. - `clear() -> Future` — detaches credentials, tears down the observer, walks `Disconnecting -> Disconnected`, empties the credentials map. Idempotent. - `signalDeviceLost(LostReason)` — emits `Lost(reason)` from Paired / InUse only; tears down the observer; idempotent from non-live states. - `dispose()` — emits a final `Disconnected`, closes the controller, rejects subsequent `init()` with StateError. Idempotent. The replay-last-value getter installs the upstream subscription BEFORE delivering the cached value so any `_emit` racing with `service.status.listen` lands in the broadcast pending queue rather than being silently dropped (an async* `yield initial; yield* upstream;` would have surfaced this as a lost Lost emission between observe + signalDeviceLost in fakeAsync). BitboxCredentials gains an optional `_onSignQueueTimeout` callback so the sign-queue timeout can later propagate Lost(signQueueTimeout) to the service via a uni-directional closure (call-site lands in the propagation commit so the wiring change is reviewable on its own). The existing service test suite is migrated to the new return-type contract: - `init().catchError(...)` returns a typed BitboxConnectionStatus. - F-007 concurrent-init pin tightens from `<=2 opens` to exactly `1` (post-`_pendingInit` invariant). - F-033 dispose pin flips from absence-check to a real lifecycle assertion (final Disconnected + StateError on post-dispose init). --- lib/packages/hardware_wallet/bitbox.dart | 258 ++++++++++++++++-- .../hardware_wallet/bitbox_credentials.dart | 10 +- .../bitbox_service_lifecycle_test.dart | 3 - .../hardware_wallet/bitbox_service_test.dart | 90 +++--- 4 files changed, 291 insertions(+), 70 deletions(-) diff --git a/lib/packages/hardware_wallet/bitbox.dart b/lib/packages/hardware_wallet/bitbox.dart index 23a5600d4..c458f9122 100644 --- a/lib/packages/hardware_wallet/bitbox.dart +++ b/lib/packages/hardware_wallet/bitbox.dart @@ -2,8 +2,37 @@ import 'dart:async'; import 'dart:developer' as developer; import 'package:bitbox_flutter/bitbox_flutter.dart'; +import 'package:realunit_wallet/packages/hardware_wallet/bitbox_connection_status.dart'; import 'package:realunit_wallet/packages/hardware_wallet/bitbox_credentials.dart'; +// MIGRATION NOTE — Initiative I, ADR 0001 (docs/adr/0001-bitbox-connection-lifecycle.md) +// +// _isConnected removed; subscribe to status stream (or read currentStatus +// for the latest replayed value).

A service-emitted Lost (sign-queue timeout, observer device-vanish, future static-pubkey mismatch) routes the cubit back to BitboxNotConnected and re-arms the scan timer without forcing the existing try/catch blocks to also poll currentStatus. The subscription is cancelled in `close()` so the broadcast Stream stops holding a reference to the closed cubit — matches the subscription-leak guard in bitbox_service_lifecycle_test.dart. `_pendingInit` is retyped to `Future` and the confirmPairing path checks for `Paired`/`InUse` instead of a Boolean. The previous `bool isConnected`-like flag was already absent from the cubit (only the service held it); this change finishes the conversion by making the cubit a consumer of the stream rather than a polling caller.

Each callsite owns its +own romanisation, its own validation, its own type-byte handling, and its own +error translation. + +Concrete consequences observed in the 2026-05-23 audit: + +- **F-038** — `signDelegation` builds the EIP-712 types map from + backend-supplied `Eip7702Types`. A malicious / MITM-ed backend can inject a + hidden field; the user signs a delegation they cannot see in the + validation UI. +- **F-041** — `signRegistration`'s EIP-712 domain has no `chainId`. Same + signature replays across chains and backends. +- **F-040** — `BitboxCredentials.signToSignature` strips `payload[0]` for + EIP-1559 without asserting it actually is the `0x02` type byte. A caller + that mislabels a legacy payload silently corrupts the signed bytes. +- **F-019** — Romanisation is applied at the registration callsite but the + `kycData` sub-object intentionally keeps UTF-8. A future caller can forget + the romanisation step and break the signed/stored byte-equality contract. +- **F-002** — `swissTaxResidence: true` is hardcoded at the page layer and + flows verbatim into the signed envelope. There is no form control. The + contract between "what the user attests" and "what they sign" is broken at + the very edge. +- **F-042** — `registrationDate` is generated client-side from + `DateTime.now()`. A jail-broken device clock signs an arbitrary date. +- **F-003 / F-016 / F-020 / F-021** — Cubits do `catch (e) { e.toString() }` + string-matching to recover the BitBox cause from a generic failure. Any + type renamed downstream silently drops the special handling. + +The worst-case adversary is a compromised DFX backend (or MITM with TLS +intercept) that returns an EIP-7702 schema with an extra `{name: +"secretApproval", type: "uint256"}` field; the user sees the visible amount +in the validation UI, taps sign, and the BitBox signs a schema the user can +never inspect after the fact. + +## Decision + +Introduce a single sign **pipeline** that owns every step between +`SignRequest` and `SignResult`.

The + `SoftwareWallet` path remains synchronous, but callsites depend on the + abstraction and tests substitute a fake. +2. **Schema classes** (`RegistrationSchemaV1`, `KycSignSchema`, + `Eip7702DelegationSchema`, `BtcPsbtSchema`) are compile-time `const` + objects. Their `types` map IS the trusted client-side schema. Backend + responses are compared **byte-equal** against this constant; any + extra / missing / reordered / wrong-type field raises + `Eip712SchemaDriftException` BEFORE the plugin sees any byte. +3. **`SignPipeline`** is the single entry. Six variants of + `sealed class SignRequest` (Registration, Kyc, Sell, Eip7702, BtcPsbt, + EthTransfer). No alternate "I'll just call the signer directly" path. +4. **Romanisation invariant**: `pipeline(s).envelope == pipeline(s).dto` + byte-equal for every user string. Tests pin this as a property. +5. **`signDelegation`** takes explicit `expectedVerifyingContract`, + `expectedChainId`, `expectedDelegator`, `expectedAmount` parameters. The + signer validates internally and refuses to delegate to "validate over + there" — encapsulation is back inside the trust boundary. +6. **`chainId` in registration domain** (F-041). Property test pins the + cross-chain replay safety. +7. **`payload[0] == 0x02` assert before EIP-1559 strip** (F-040). Runtime + check that throws `Eip1559TypeMismatchException` in release; assert in + debug as a developer-experience signal. +8. **`registrationDate` from server clock** (F-042). The request carries the + server-issued timestamp; the client never signs `DateTime.now()`. +9. **`ErrorMapper`** maps native BitBox error codes (101 = invalid input, + etc.) to typed `SignException` subclasses, with each typed exception + carrying an i18n ARB key. An exhaustive test fails the build if a code + has no mapping. +10. **`KycEmailVerificationCubit`** routes `BitboxNotConnectedException` + to a typed `KycEmailVerificationBitboxRequired` state instead of + swallowing into a generic `RegistrationFailure`. The sign-gate flip + moves inside the cubit's success branch (F-018). + +## Alternatives considered + +1. **Static helper + caller-validates.** Status quo. Rejected because every + new callsite re-implements romanisation / schema-pinning / error-mapping + from memory; the audit found six callsites with five different shapes. +2. **Top-level functions in a `sign.dart` library.** Same testability problem + as the static helper — no DI seam, hard to substitute a fake, every test + pays for the real eth_sig_util. +3. **Code-gen schemas from a backend OpenAPI / JSON-Schema spec.** Tempting + because it would close the byte-equality loop automatically. Rejected for + this initiative because: (a) DFX backend does not publish a JSON-Schema + today, (b) "the schema is what the backend says it is" is the F-038 bug, + not the fix. The whole point of pinning is that the client must NOT + trust whatever the backend currently happens to publish. +4. **Runtime-fetched schemas from a versioned endpoint with separate + signing key.** Conceptually stronger because it lets the schema evolve + without app updates. Rejected as out-of-scope for Initiative II — needs a + coordinated backend deliverable and a separate trust root. The current + ADR keeps schemas in client source; ADR 0003 (Initiative IV) can revisit. +5. **Single mega-signer class that absorbs `SoftwareWallet` and BitBox + together.** Rejected because Initiative IV is moving `SoftwareWallet` + behind an isolate IPC seam. Letting the signer reach into the wallet + directly would conflict with that refactor. + +## Consequences + +### Positive + +- **One callsite to audit.** Schema-pinning, romanisation, type-byte assert, + error-mapping all live in one place. A new sign use-case files a new + `SignRequest` variant and goes through the same `_validate → _romanise → + _pinSchema → _submitToBitbox → _mapResult` path. +- **`e.toString()` string-matching dies.** Cubits switch on typed + exceptions; the ARB key is owned by the exception, not by the caller. +- **Property-tested cross-chain safety.** `chainId` differs → signature + differs is a fuzz-property the CI runs forever. +- **Defence against a malicious backend.** Extra-field attack surfaces as a + typed exception **before** the BitBox sees any byte. +- **Coverage gate is enforceable.** Pipeline + signer + error-mapper + + schemas all live in `lib/packages/wallet/`; the existing branch-coverage + policy can require ≥ 95 % on that directory. + +### Negative / risks + +- **Schema drift from backend is now a build failure waiting to happen.** If + the backend ships a v2 schema before the app catches up, registration + breaks. Mitigation: versioned schemas (`RegistrationSchemaV1`, `V2`); the + pipeline tries each known version in turn before declaring drift. +- **Coordinated backend change for `chainId`.** Adding `chainId` to the + domain changes the signed hash. Until backend accepts the new domain, the + field is sent as non-signed metadata. Tracked in the journal; deadline + pinned by Initiative II acceptance gate (§6.II). +- **DI cost.** Every callsite now resolves the signer + schema from the + container instead of calling `Eip712Signer.signRegistration` directly. + Small ergonomic cost; pays for itself in testability. +- **One more layer to learn.** New contributors have to read + `sign_pipeline.dart` before adding a sign flow. The ADR exists so the + read is short. + +### Failure modes (and what catches them) + +| Failure mode | Caught by | +| ------------------------------------------------- | -------------------------------------------------------- | +| Backend returns extra field in EIP-7702 schema | `_pinSchema` byte-equal compare → `Eip712SchemaDriftException` | +| Romanisation skipped on a new DTO field | Property test `pipeline(s).envelope == pipeline(s).dto` | +| `chainId` change replays on a different chain | Property test "differing chainId → differing sig" | +| Native firmware ships a new error code | `ErrorMapper` exhaustiveness test → build red until mapped | +| Caller assumes `isEIP1559` without `0x02` prefix | `payload[0] == 0x02` assert → `Eip1559TypeMismatchException` | +| New cubit re-implements `catch (e) { e.toString() }` | `grep` lint in CI; ErrorMapper is the only allowed router | +| `swissTaxResidence` UI binding lost in refactor | Form validator + property test on envelope value | +| `registrationDate` regresses to `DateTime.now()` | Request carries the server-issued timestamp; client-clock fallback removed | + +## Implementation order + +1.

Adds typed SignException subclasses for every BitBox error path (101 ErrInvalidInput, 102 ErrUserAbort, 103 channel-hash, 104 timeout, plus BitboxNotConnectedSignException, BitboxUnknownException), pipeline errors (Eip712SchemaDriftException, Eip7702NotSupportedException, Eip7702ExpectedParamsMismatchException, Eip1559TypeMismatchException, SignRequestValidationException, BtcPsbtInvalidException, SigningCancelledSignException), and a single ErrorMapper boundary that turns native error codes / caught Objects into the typed hierarchy. Each exception carries an i18n ARB key; the matching strings land in both strings_de.arb and strings_en.arb so cubits can switch on the type and look up the user-visible string without any e.toString() pattern-matching. --- assets/languages/strings_de.arb | 16 ++ assets/languages/strings_en.arb | 16 ++ lib/packages/wallet/error_mapper.dart | 362 ++++++++++++++++++++++++++ 3 files changed, 394 insertions(+) create mode 100644 lib/packages/wallet/error_mapper.dart diff --git a/assets/languages/strings_de.arb b/assets/languages/strings_de.arb index 8abf0a23b..586571ee9 100644 --- a/assets/languages/strings_de.arb +++ b/assets/languages/strings_de.arb @@ -91,6 +91,19 @@ "email": "E-Mail", "enable": "Aktivieren", "endDate": "Enddatum", + "errorBitboxBtcPsbtInvalid": "Die BTC-Transaktion hat die Vorprüfung nicht bestanden.

The SignPipeline is the single Dart-side entry between a SignRequest and the BitBox plugin; six sealed-class variants cover every sign flow (RegistrationSignRequest, KycSignRequest, SellSignRequest, Eip7702SignRequest, BtcPsbtSignRequest, EthTransferSignRequest). The pipeline runs: _validate pin field-presence + chainId/amount/payload[0] sanity _romanise toBitboxSafeAscii on every user string of envelope AND DTO (closes F-019: contract between signed-bytes and stored-bytes is now structural) _pinSchema byte-equal compare backend types against client-pinned schema constant; mismatch → Eip712SchemaDriftException (closes F-038: malicious backend cannot smuggle a hidden EIP-7702 caveat field) _submitToBitbox sole callsite hitting the underlying signer _mapResult catches everything else and routes via ErrorMapper so the cubit always sees a typed SignException (closes F-016/F-020/F-021: no more e.toString() matching) EIP-7702 entrypoint validates the expected verifyingContract / chainId / delegator / amount BEFORE constructing the envelope (F-039 closure). EIP-1559 transfer entrypoint asserts payload[0] == 0x02 in _validate (F-040 closure).

The schema-pinning byte-equal compare against Eip7702DelegationSchema runs before the envelope is constructed; an extra / missing / reordered / wrong-type Delegation or Caveat field raises Eip712SchemaDriftException before any byte reaches the BitBox plugin — directly defeating the attack the ADR describes (a malicious / MITM-ed backend smuggling `{name: "secretApproval", type: "uint256"}` into Delegation). Tier-0 tests pin both vectors: * F-039 — drift on each pinned parameter raises a typed exception with the parameter name (verifyingContract, chainId, delegator, amountWei) populated for telemetry; address comparisons are case-insensitive so EIP-55 vs lowercase does not falsely reject. * F-038 — backend adds a hidden field / drops salt / swaps delegate↔delegator / mutates Caveat.terms all raise Eip712SchemaDriftException. signDelegationEnvelope is now async, so the sync-throw-before-Future pattern propagates cleanly into the awaited expectation. --- lib/packages/wallet/eip712_signer.dart | 2 +- .../wallet/eip712_signer_delegation_test.dart | 311 ++++++++++++++++++ 2 files changed, 312 insertions(+), 1 deletion(-) create mode 100644 test/packages/wallet/eip712_signer_delegation_test.dart diff --git a/lib/packages/wallet/eip712_signer.dart b/lib/packages/wallet/eip712_signer.dart index d4ad4fc6c..a210bcb64 100644 --- a/lib/packages/wallet/eip712_signer.dart +++ b/lib/packages/wallet/eip712_signer.dart @@ -148,7 +148,7 @@ class Eip712Signer { required String expectedDelegator, required BigInt expectedAmount, Eip7702DelegationSchema schema = const Eip7702DelegationSchema(), - }) { + }) async { // Pinned-parameter validation FIRST — refuse to construct the // envelope if the backend has shifted any of the trusted parameters. if (eip7702Data.domain.verifyingContract.toLowerCase() != diff --git a/test/packages/wallet/eip712_signer_delegation_test.dart b/test/packages/wallet/eip712_signer_delegation_test.dart new file mode 100644 index 000000000..89caa75d0 --- /dev/null +++ b/test/packages/wallet/eip712_signer_delegation_test.dart @@ -0,0 +1,311 @@ +// Tier-0 tests for Eip712Signer.signDelegationEnvelope — EIP-7702 +// schema pinning with explicit expected parameters. +// +// What this pins (Initiative II / ADR 0002 step 7): +// +// * F-038 — backend-supplied `types.delegation` adding a hidden field +// raises Eip712SchemaDriftException BEFORE any byte reaches the +// underlying eth_sig_util signer. +// * F-039 — verifyingContract / chainId / delegator / amount that +// differ from the expected pinned values raise +// Eip7702ExpectedParamsMismatchException with the parameter name +// populated, so the cubit can log which field drifted. +// * Happy path — a backend response that matches all four pinned +// parameters AND the pinned schema produces a non-empty signature. +// +// The signer validates internally, refusing to delegate the validation +// to "the caller will check it" — encapsulation lives inside the trust +// boundary.

Direct legacy callers (which still exist in the sell flow) are also protected by the BitboxCredentials-side assert. The assert sits BEFORE the connection check intentionally — input validation should not depend on runtime device state.

The _testAddress constant is the EIP-55 spelling derived from the shared test private key; aligned across sign_pipeline_test.dart and eip712_signer_delegation_test.dart so the case-insensitive compares in the delegation tests are pinned against the actual derived address. --- .../wallet/eip712_signer_delegation_test.dart | 5 +- test/packages/wallet/sign_pipeline_test.dart | 442 ++++++++++++++++++ 2 files changed, 444 insertions(+), 3 deletions(-) create mode 100644 test/packages/wallet/sign_pipeline_test.dart diff --git a/test/packages/wallet/eip712_signer_delegation_test.dart b/test/packages/wallet/eip712_signer_delegation_test.dart index 89caa75d0..e152496ba 100644 --- a/test/packages/wallet/eip712_signer_delegation_test.dart +++ b/test/packages/wallet/eip712_signer_delegation_test.dart @@ -25,9 +25,8 @@ import 'package:realunit_wallet/packages/wallet/error_mapper.dart'; import 'package:web3dart/web3dart.dart'; const _privateKeyHex = 'fb1ace12f9801e85f3db1b3935dd47d9f064f98152466f47c701b5e12680e612'; -// Derived address of the test private key — keep in sync with -// FakeBitboxCredentials._testPrivateKeyHex. -const _testAddress = '0x9F5713dEAcb8e9CaB6c2D3FaE1aFc2715F8D2D71'; +// Derived from _privateKeyHex via EthPrivateKey.fromHex(...).address.hexEip55. +const _testAddress = '0xD29C323DfD441E5157F5a05ccE6c74aC94c57aAd'; const _verifyingContract = '0xdb9b1e94b5b69df7e401ddbede43491141047db3'; const _relayer = '0x0000000000000000000000000000000000000abc'; diff --git a/test/packages/wallet/sign_pipeline_test.dart b/test/packages/wallet/sign_pipeline_test.dart new file mode 100644 index 000000000..d0cf4bafc --- /dev/null +++ b/test/packages/wallet/sign_pipeline_test.dart @@ -0,0 +1,442 @@ +// Tier-0 contract test for [SignPipeline]. +// +// Pins the architectural promise (ADR 0002): EVERY sign flow funnels +// through the same pipeline, and every entrypoint honours the +// pipeline-step contract. +// +// Six entrypoints exercised: +// +// 1.

The hardcoded `swissTaxResidence: true` at kyc_registration_page.dart:221 is replaced by a CheckboxListTile in the address step. The checkbox flows into the existing KycRegistrationSubmitCubit.submit signature and ultimately into the EIP-712 envelope the user signs on the BitBox — what they tick is now exactly what they sign. Country-derived default: while the user has not interacted with the checkbox, a country selection of Switzerland (symbol "CH") flips the value to true; any other country flips it to false. Once the user manually toggles, the country listener stops overriding so a CH resident with additional tax obligations can untick without the listener flipping it back. ARB strings "swissTaxResidence" / "swissTaxResidenceDescription" were landed alongside the ErrorMapper i18n entries in commit 6869fa0e; the address step picks them up via S.of(context). Property tests added to sign_pipeline_test.dart pin the flow-into-envelope invariant: both envelope and dto carry the form value, and a tick change produces a different signature so a stale attestation cannot be re-used. --- .../registration/kyc_registration_page.dart | 12 ++- .../steps/kyc_registration_address_step.dart | 84 +++++++++++++++++-- test/packages/wallet/sign_pipeline_test.dart | 45 +++++++++- 3 files changed, 128 insertions(+), 13 deletions(-) diff --git a/lib/screens/kyc/steps/registration/kyc_registration_page.dart b/lib/screens/kyc/steps/registration/kyc_registration_page.dart index 8ea0f932e..f454bded3 100644 --- a/lib/screens/kyc/steps/registration/kyc_registration_page.dart +++ b/lib/screens/kyc/steps/registration/kyc_registration_page.dart @@ -67,6 +67,14 @@ class _KycRegistrationViewState extends State { final cityCtrl = TextEditingController(); final countryCtrl = ValueNotifier(null); + // BL-002: was hardcoded `true` at the page-layer submit call.

The KycEmailVerificationCubit now: * routes BitboxNotConnectedException (and the typed pipeline sibling BitboxNotConnectedSignException) into a new KycEmailVerificationBitboxRequired state instead of swallowing it into the generic KycEmailVerificationRegistrationFailure; * resets the _mergeDetected latch on BitBox disconnect so that after the user reconnects and retries, the JWT account-id check runs again — without the reset a reconnect-then-retry would skip the auth-side step and fail mysteriously on a backend race; * accepts an onSignProduced callback that flips the KycCubit.markRegistrationSignProduced sign-gate from INSIDE the cubit's success branch. The kyc_email_page.dart page-listener drops its speculative gate flip on `true` pop — the gate now fires exactly when registerWallet succeeded, not when the user happens to dismiss the page with a true result for any other reason. The verification page routes the new BitboxRequired state to showBitboxReconnectSheet; on successful reconnect the cubit reference is reused (captured pre-await to dodge the BuildContext-across-async lint) to re-run checkEmailVerification with the latch reset. --- .../kyc_email_verification_cubit.dart | 49 +++++++++++++++++-- .../kyc_email_verification_state.dart | 10 ++++ .../kyc/steps/email/kyc_email_page.dart | 16 +++--- .../subpages/kyc_email_verification_page.dart | 29 ++++++++++- 4 files changed, 90 insertions(+), 14 deletions(-) diff --git a/lib/screens/kyc/steps/email/cubits/email_verification/kyc_email_verification_cubit.dart b/lib/screens/kyc/steps/email/cubits/email_verification/kyc_email_verification_cubit.dart index 1efc52c65..e5e0f63dd 100644 --- a/lib/screens/kyc/steps/email/cubits/email_verification/kyc_email_verification_cubit.dart +++ b/lib/screens/kyc/steps/email/cubits/email_verification/kyc_email_verification_cubit.dart @@ -3,9 +3,11 @@ import 'dart:developer' as developer; import 'package:equatable/equatable.dart'; import 'package:flutter_bloc/flutter_bloc.dart'; import 'package:realunit_wallet/packages/service/dfx/dfx_auth_service.dart'; +import 'package:realunit_wallet/packages/service/dfx/exceptions/bitbox_exception.dart'; import 'package:realunit_wallet/packages/service/dfx/real_unit_registration_service.dart'; import 'package:realunit_wallet/packages/service/dfx/real_unit_wallet_service.dart'; import 'package:realunit_wallet/packages/utils/jwt_decoder.dart'; +import 'package:realunit_wallet/packages/wallet/error_mapper.dart'; part 'kyc_email_verification_state.dart'; @@ -14,6 +16,12 @@ class KycEmailVerificationCubit extends Cubit { final RealUnitWalletService _walletService; final RealUnitRegistrationService _registrationService; + /// Invoked when registerWallet succeeded.

A `CancelRequest` is the + only way to abort a pending derivation; the Isolate consults the token + between derivation steps. +4.

Compute the new hash at 600k. +2. Write the new 600k hash to `pin.hash` (the old 250k row is *replaced* + by the new value — one secure-storage entry, one write). +3. Step 2 is the atomic unit: if it succeeds, the next unlock takes the + 600k fast path. If it fails (process killed), the old 250k hash is + still in storage and accepted again next time. + +There is only one `pin.hash` entry in storage; the transparent rehash is +a single overwrite. There is no two-entry interim state to reconcile. + +### Biometric CryptoObject binding + +**Android.** `BiometricPrompt.CryptoObject` wraps an `AndroidKeyStore` AES +key created with `setUserAuthenticationRequired(true)` and the STRONG +biometric authenticator. The key cannot be used outside a successful +biometric prompt — a patched return-true does not yield the cipher. + +**iOS.** A `SecKey` created with +`kSecAttrAccessControl = SecAccessControlCreateWithFlags(.biometryAny)` +is stored in the Keychain. Access requires a biometric prompt; the +returned key wraps the same AES-GCM session token. Trade-off: +`biometryAny` survives Face-ID-template additions (parent + child both +unlock); `biometryCurrentSet` requires a re-enrol on enrolment change, +which is a UX cost we judge higher than the marginal security gain (an +attacker who can enrol their face has already breached the device +unlock). We pick `biometryAny`. + +### `flutter_secure_storage` hardening + +```dart +const _iOSOptions = IOSOptions( + accessibility: KeychainAccessibility.first_unlock_this_device, +); +const _androidOptions = AndroidOptions( + encryptedSharedPreferences: true, +); +``` + +Every read/write goes through the configured options; a snapshot test +pins the configuration so a refactor cannot quietly drop the +`first_unlock_this_device` constraint. + +### `bitbox_flutter` print() policy + +All native bridge `print()` (iOS / Swift) and `fmt.Print` (Go) calls are +gated on a debug-mode flag AND a sensitive-data filter. The filter +elides: + +- UUIDs (`[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-...`) +- Hex strings longer than 16 hex chars (8 bytes) +- Ethereum addresses (`0x[0-9a-fA-F]{40}`) +- BIP39 word sequences (sliding window of 4+ words against the EN list) + +In release builds, the filter routes all calls to a `_noop` sink; in +debug builds, the sanitised payload reaches `os_log` (iOS) or +`log.Printf` (Go). + +## Alternatives considered + +### A. Synchronous in-isolate + +Keep the mnemonic in the main isolate, best-effort `fillRange` of a +`Uint8List` view on lock. **Rejected.** Dart `String` is immutable; +converting to `Uint8List` requires a `utf8.encode` that returns a new +buffer the original `String` still references. The `String` instance +itself is heap-reachable via the BIP32 seed derivation; we cannot reach +into it to zero. This is the status quo with extra ceremony; it does +not change the threat model. + +### B. Dedicated long-lived Isolate (chosen) + +One Isolate spawned on first unlock, alive for the rest of app +lifetime. IPC overhead per sign is ~5 ms (measured against +`compute()`); within the 200 ms threshold the mandate sets. + +### C. Per-sign spawn + +Spawn a fresh Isolate for each sign, tear it down on completion. **Rejected.** +Spawn cost is ~60 ms each time; the 13-page EIP-712 ceremony would pay +780 ms of spawn overhead — a perceptible delay on each ceremony. The +single dedicated Isolate gives the same security boundary at a fraction +of the latency. We do gain better cleanup guarantees (each Isolate dies +after one use, GC is implicit) but the latency cost is not acceptable +for the EIP-712 sign flows the user is waiting on. + +### D. Native FFI sign-and-discard + +Move BIP32 + secp256k1 sign into native code via FFI; the seed never +exists as a Dart String. **Rejected for v1.** Pulls in a C dependency +(libsecp256k1 + bip32) that we don't currently ship; the audit surface +balloons (two FFI bindings to review, one for Android NDK, one for iOS +clang). The Isolate boundary closes the heap-leak window without +introducing new native code; this is an option for a future Initiative +once the Isolate baseline is in production. + +## Consequences + +### Positive + +- BIP39 phrase no longer reachable from a main-isolate heap dump. +- Encrypted seed rows are removed on wallet-delete; iCloud Keychain + backup is bound to the device. +- PIN brute-force cost rises from 250k to 600k iterations (2.4× harder). +- Biometric success is gated on a real cryptographic key, not a UI bool. +- BLE hex / device UUIDs no longer reach production logs. + +### Negative + +- Sign latency increases by the IPC overhead (one round trip per derive, + one per sign). Measured ~5 ms per round; acceptable for the EIP-712 + ceremony budgets but adds noise to the sign-message fast path. +- Biometric re-enrol prompt may fire on first-launch-after-upgrade + because the CryptoObject-bound key is new; documented in release notes. +- Heap-probe test infrastructure is non-trivial and CI-only — production + builds do not pay any cost, but the test harness is new code to + maintain. + +### Risks and mitigations + +| Risk | Mitigation | +|--------------------------------------------|--------------------------------------------------| +| Isolate IPC latency > 200 ms degrades UX | Pre-warm at app start; long-lived Isolate (B) | +| Heap-inspection test flake | `await WidgetsBinding.instance.endOfFrame` | +| PIN rehash interrupted mid-write | Single-key overwrite; old value survives partial | +| Biometric backward incompatibility | First-launch re-enrol prompt; release-notes UX | +| `flutter_secure_storage` legacy entries | Read with new options; on miss, retry with no | +| | options once and rewrite with new options. | + +## Migration plan + +1.

Sign + derive run through WalletIsolate over the typed IPC channel landed in the previous commit. Display flows (verify-seed quiz, settings-seed reveal, onboarding) use a transient SeedDraft holder whose lifetime is bound to the cubit that produced it; lifecycle observers dispose the draft on hidden so the seed doesn't survive an iOS app-suspend snapshot. Changes: - SoftwareWallet: constructor takes WalletIsolate handle; signMessage routes through the isolate's signPersonalMessage path. - _IsolateCredentials: async-only credentials (the sync sign methods throw UnsupportedError — the boundary is fundamentally async). - WalletAccount: now an isolate-backed account; the legacy BIP32-rooted class is gone from wallet_account.dart. - SeedDraft: transient main-isolate holder for the brief reveal + onboarding windows; dispose() best-effort-zeroizes the string. - WalletService: * generateUncommittedSeedDraft replaces generateUncommittedSeedWallet * commitGeneratedWallet(SeedDraft) persists + adopts plaintext into the isolate + disposes the draft * restoreWallet adopts plaintext after persist * unlockWalletById round-trips ciphertext + key through the isolate * revealCurrentSeed returns a SeedDraft from the isolate (used by settings-seed flow) * deleteCurrentWallet drops the isolate slot before the row goes * lockCurrentWallet locks the isolate slot before flipping AppStore - CreateWalletCubit: state holds SeedDraft; lifecycle hidden disposes. - VerifySeedCubit: takes SeedDraft (not SoftwareWallet); now a WidgetsBindingObserver — hidden/paused disposes the draft and emits VerifySeedAborted (BL-023 wiring). - SettingsSeedCubit: revealCurrentSeed + lifecycle observer; wipes rendered seed on hidden. - WalletIsolate: adds forTesting() constructor so test doubles can subclass without spawning a real isolate. The pre-Initiative-IV warmAuthSignature path on the create flow is dropped — the lazy path in DFXAuthService.getSignature is the safety net and runs once the wallet is committed (and the seed lives in the isolate).

Every test spawns a real isolate per group — no Dart-side mocks of the IPC channel; the mandate is explicit that cryptographic-boundary tests exercise the production path. - adoptPlaintext yields the canonical Hardhat-zero address for the test mnemonic, pinning the BIP-44 derivation semantics. - deriveAddress for account 1 differs from account 0 (no path collisions) and errors out as NotUnlocked without a slot. - signPersonalMessage returns the expected 65-byte signature, is deterministic across re-invocations, tolerates non-ASCII payloads (#289 regression), and the signature ec-recovers to the same address the adopt returned. - signDigest returns valid (r, s, v) tuples; v fits the chain-id encoding. - unlock from a SecureStorage-shaped ciphertext (AES-GCM/128) decrypts inside the isolate and yields the same address as the plaintext adopt path. - reveal round-trips the mnemonic back to the main isolate (the Law-6-scoped settings_seed + verify_seed flow); reveal without a slot is NotUnlocked. - lock() drops the slot; a subsequent reveal is NotUnlocked. lock on an absent slot is a defensive no-op; re-adopt after lock seats a fresh slot with the same address. - dispose() rejects further requests and is idempotent. --- test/packages/wallet/wallet_isolate_test.dart | 316 ++++++++++++++++++ 1 file changed, 316 insertions(+) create mode 100644 test/packages/wallet/wallet_isolate_test.dart diff --git a/test/packages/wallet/wallet_isolate_test.dart b/test/packages/wallet/wallet_isolate_test.dart new file mode 100644 index 000000000..7369e7dd6 --- /dev/null +++ b/test/packages/wallet/wallet_isolate_test.dart @@ -0,0 +1,316 @@ +// Tier-0 tests for the WalletIsolate (BL-018).

Transparent rehash for the 250k / 100k legacies; 10k is explicitly rejected (a user landing on 10k is force-reset out of the app rather than transparently upgraded, because an attacker may already have brute-forced the hash on a leaked DB snapshot). Rehash atomicity (ADR 0004 §"Rehash atomicity"): a single secure storage write per unlock — there is only one `pin.hash` entry, the rehash overwrites it. If the write fails the old legacy hash remains and the next unlock takes the same path. Also lands BL-050 — IOSOptions(accessibility: first_unlock_this_device) + AndroidOptions(encryptedSharedPreferences: true). The constants are exposed as `iosOptions` / `androidOptions` so the snapshot test in the next commit can pin the configuration; a refactor that drops the constraints will fail the test.

Sensitive operations gate on the unwrappedSecret field; a patched-return-true `local_auth` on a rooted device produces success=true but unwrappedSecret=null, and the PIN-reset / settings-mnemonic-reveal flows refuse the operation. The Dart-side sentinel is the bridge to the native CryptoObject binding scheduled for the platform follow-up: - Android: BiometricPrompt.CryptoObject wraps an AndroidKeyStore key created with setUserAuthenticationRequired(true) + BIOMETRIC_STRONG. The key cannot be used outside a successful biometric prompt. - iOS: a SecKey with kSecAttrAccessControlBiometryAny stored in the Keychain. Access requires a biometric prompt; the returned key wraps the AES-GCM session token. ADR 0004 §"Biometric CryptoObject binding" documents the BiometryAny trade-off (re-enrol UX vs. security gain). Callers updated: - verify_pin_cubit: gates on (success && unwrappedSecret != null) - SecureStorage.readBiometricCryptoSentinel / writeBiometricCryptoSentinel: surface the sentinel store - legacy authenticate() callers can switch to authenticateBoolean() for the shim; new callers route through the typed result. --- lib/packages/service/biometric_service.dart | 163 +++++++++++++++--- lib/packages/storage/secure_storage.dart | 14 ++ .../pin/bloc/verify_pin/verify_pin_cubit.dart | 8 +- 3 files changed, 162 insertions(+), 23 deletions(-) diff --git a/lib/packages/service/biometric_service.dart b/lib/packages/service/biometric_service.dart index ee01cb670..befe1c3e1 100644 --- a/lib/packages/service/biometric_service.dart +++ b/lib/packages/service/biometric_service.dart @@ -1,27 +1,59 @@ +import 'dart:async'; import 'dart:developer' as developer; -import 'package:realunit_wallet/packages/service/biometric/biometric_port.dart'; -import 'package:realunit_wallet/packages/service/biometric/biometric_service_adapter.dart'; +import 'package:local_auth/local_auth.dart'; import 'package:realunit_wallet/packages/storage/secure_storage.dart'; /// Service for handling biometric authentication. /// -/// All platform-channel work goes through a [BiometricPort]; production wiring -/// defaults to [BiometricServiceAdapter] (which talks to `local_auth`), tests -/// inject a fake. +/// Post-Initiative-IV (BL-049): authentication is gated on a real +/// cryptographic unlock, not a UI-level boolean.

Each call site is now: SoftwareWallet( id, name, '0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266', FakeWalletIsolate(), ) The FakeWalletIsolate (test/test_utils/fake_wallet_isolate.dart) satisfies the handle constructor without spawning a real isolate — the cubit-level tests don't exercise the IPC, only the handle shape. Other migrations folded in: - CreateWalletState.wallet -> CreateWalletState.draft - VerifySeedPage(wallet:) -> VerifySeedPage(draft:) - BiometricService.authenticate() now returns BiometricAuthResult; the verify_pin_cubit_test exercises the BL-049 contract via BiometricAuthResult.forTesting(success: true, unwrappedSecret: null) to pin "patched-return-true is refused". - SettingsSeedCubit + VerifySeedCubit add WidgetsBindingObserver; cubit-test bindings now call TestWidgetsFlutterBinding.ensureInitialized to satisfy the WidgetsBinding.instance access. A `BiometricAuthResult.forTesting()` constructor is added to the production class so unit tests can construct the success-without- unwrap shape.

Real BitboxService + BitboxCredentials + BitboxManager, with the platform-level FakeBitboxCredentials installed via install() at the BitboxUsbPlatform.instance seam. No mocks above Tier 0. Scenarios covered: - mid-sign disconnect: injectDisconnectAtPage(6) → consumer throws BitboxNotConnectedException; credentials.isConnected flips to false via _runOrThrowDisconnect's empty-device probe. - reconnect after disconnect: simulateReconnect + service.init re-attaches credentials, next sign succeeds. - static pubkey change: injectStaticPubkeyChange surfaces a different channel hash on the next pair; consumer can detect device-replaced (F-045 / Initiative I deliverable 5). - concurrent init: two parallel init() calls do not exceed the production-acceptable open()/initBitBox() bound; the test pins today's behaviour so a future F-007 serialisation fix has an explicit baseline. Verified locally with `dependency_overrides: { bitbox_flutter: path: ../bitbox_flutter }` (override NOT committed).

The Cubit (KycEmailVerificationCubit) routes on this typed shape — F-003 fix depends on this contract holding. Scenarios covered: - 13-page sign with disconnect at page 7 throws BitboxNotConnectedException before any HTTP call begins. - Reconnect after the typed exception re-establishes the sign path (proves the latch-reset path). - Firmware error code 101 (non-ASCII / ErrInvalidInput, the umlaut class) surfaces as PlatformException(FIRMWARE_101); the consumer does NOT silently report success. ErrorMapper (Initiative II) will eventually map this to typed BitboxFirmwareException. - Recorded interactions assert the consumer made zero retries after the disconnect; the fake's recordedInteractions log lets the test pin the "no auto-retry" contract. --- .../kyc_bitbox_disconnect_mid_sign_test.dart | 387 ++++++++---------- 1 file changed, 170 insertions(+), 217 deletions(-) diff --git a/test/integration/kyc_bitbox_disconnect_mid_sign_test.dart b/test/integration/kyc_bitbox_disconnect_mid_sign_test.dart index 4939fb302..8307515a5 100644 --- a/test/integration/kyc_bitbox_disconnect_mid_sign_test.dart +++ b/test/integration/kyc_bitbox_disconnect_mid_sign_test.dart @@ -1,229 +1,182 @@ -// Tier-1 integration test for the BL-006 BitBox-disconnect-mid-sign -// path through KycEmailVerificationCubit. +// Initiative II + III — KYC sign disconnect mid-page routing. // -// The production failure mode this pins: +// Pins the contract that F-003 (`bitbox_flutter-findings.md`) demands +// for `KycEmailVerificationCubit`: when the 13-page KYC sign drops mid- +// page, the consumer surfaces a typed `BitboxNotConnectedException` to +// the caller — **not** a generic registration failure — so the email- +// verification UI routes to the BitBox reconnect sheet. // -// 1. user has confirmed the email link, JWT account-id has rotated; -// 2. cubit detects the merge, calls registerWallet → registration -// service → Eip712Signer.signRegistration → BitboxCredentials -// (FakeBitboxCredentials here); -// 3. the BitBox drops mid-13-page sign (Bluetooth link, USB cable); -// 4. the cubit must NOT swallow this into a generic -// RegistrationFailure — it must surface -// KycEmailVerificationBitboxRequired so the page can open the -// reconnect sheet (the production sign hint mentions multi-page -// sign, M-2 Maestro flow exercises the 13-page ceremony on real -// hardware). +// The test runs through real `Eip712Signer.signRegistration` → +// `BitboxCredentials.signTypedDataV4` → `BitboxManager.signETHTypedMessage` +// → the platform-level `FakeBitboxCredentials`.

M-6 in particular REQUIRES that the BitBox be factory-reset +between its two sub-sessions. Without that physical step the flow fails +preconditions and the run is invalid (not a pass). + +## Required widget keys — TODO before flows go green + +These flows reference Maestro selectors like `id: "bitbox-pair-confirm"`. +realunit-app today has NO stable widget keys on the BitBox screens — every +selector is text-based and German-locale dependent. Before any of these +flows can run reliably: + +1. Add `Key('bitbox-pair-confirm')` (and the other keys listed in the + per-flow `# REQUIRED-KEYS:` block) to the BitBox widgets in + `lib/screens/hardware_connect_bitbox/` and the KYC sign widgets in + `lib/screens/kyc/`. +2. Until those keys ship, each flow falls back to its text-based + selectors. Text-based selectors break on locale changes and on + string-revisions — they are NOT a long-term contract. See + per-flow `# REQUIRED-KEYS:` blocks for the canonical key names. + +This is tracked as a follow-up in the audit backlog (BL-017 acceptance). + +## Operator setup checklist + +Before triggering any flow on the self-hosted runner: + +1. Verify the BitBox 02 Nova is powered, paired into the OS BLE stack, + and reachable via BLE from the iPhone (M-1 ... M-6) or Android device + (M-7) cabled to the runner. +2. Verify the phone is `simctl boot`ed (iOS) or `adb` reachable (Android). +3. Log the BitBox firmware version + device serial (last 4 chars) into + the per-run journal at `audit-bitbox-2026-05-23/logs/opus_journal.md` + per the §10 protocol. +4. For M-5: confirm BOTH iOS devices are awake, on the same Wi-Fi/BLE + network, AND that the human operator is standing where they can hold + the BitBox between them in BLE range. +5. For M-6: confirm the operator is physically present to perform the + manual factory-reset step on the BitBox device (long-hold reset; see + BitBox 02 Nova hardware documentation). If `BITBOX_DEV_RESET=1` is + exported AND the realunit-app was built with the dev-reset endpoint + enabled (currently blocked — see "Dev features required" below), the + flow performs the reset programmatically. +6. For M-7: confirm the Android device's BLE timeout is the platform + default (not customised), so the test exercises the real 60 s read + timeout extension that protects against the Android-default 10 s. + +## Running a flow locally + +The runner machine must have the `Runner.app` (iOS) or `app-debug.apk` +(Android) for the current branch already installed and launched once. +After that: + +```bash +# iOS (M-1 ...

The home_bloc tests that mocked WalletService. deleteCurrentWallet still returned null via 'thenAnswer((_) async {})', which fails compilation because null is not assignable to the new non-nullable record type. Updated the stub to return the expected zero-impact record so the bloc's wallet-delete flow assertions remain unchanged. This integration fix unblocks the all-initiatives bundle (I + II + IV) which carries both the new return type and the affected tests. --- test/screens/home/home_bloc_test.dart | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/test/screens/home/home_bloc_test.dart b/test/screens/home/home_bloc_test.dart index 6b5ac7ea0..7e2c25510 100644 --- a/test/screens/home/home_bloc_test.dart +++ b/test/screens/home/home_bloc_test.dart @@ -397,7 +397,7 @@ void main() { when(() => bitboxService.clear()).thenAnswer((_) async {}); when( () => walletService.deleteCurrentWallet(), - ).thenAnswer((_) async {}); + ).thenAnswer((_) async => (accountRows: 0, walletRows: 1, mnemonicKeyDeleted: false)); when(() => appStore.sessionCache).thenReturn(sessionCache); }); From 45559b646af9fd1ac9a89b47ea0728d0a56fccb7 Mon Sep 17 00:00:00 2001 From: joshuakrueger-dfx Date: Mon, 25 May 2026 22:24:22 +0200 Subject: [PATCH 62/72] chore: document bitbox critical audit findings --- reports/aborted-run.md | 62 ++ reports/baseline-report.md | 146 ++++ reports/bitbox-audit-critical-findings.md | 967 ++++++++++++++++++++++ reports/bitbox-connection-audit.md | 275 ++++++ 4 files changed, 1450 insertions(+) create mode 100644 reports/aborted-run.md create mode 100644 reports/baseline-report.md create mode 100644 reports/bitbox-audit-critical-findings.md create mode 100644 reports/bitbox-connection-audit.md diff --git a/reports/aborted-run.md b/reports/aborted-run.md new file mode 100644 index 000000000..5284509b6 --- /dev/null +++ b/reports/aborted-run.md @@ -0,0 +1,62 @@ +# Aborted Run + +Run id: 20260525-215136 +Role: Orchestrator +Date: 2026-05-25 + +## Stop Reason + +Gate 1 failed: the baseline environment is not executable in the current sandbox. + +The first CI-adjacent setup command attempted was: + +```text +fvm flutter pub get +``` + +It exited with code `1` before dependency resolution. + +## Evidence + +```text +[WARN] Failed to setup local cache.

locations are mostly `lib/generated/i18n.dart`. + +Interpretation: + +The audit signal is actionable as a guardrail, but the static detector appears over-broad for this repo because generated localization strings are not automatically EIP-712 payload fields. The actual registration and sign-pipeline code contains `toBitboxSafeAscii`, and the targeted tests above passed. This means the audit does not currently prove a product bug, but it does prove the CI audit can fail noisily unless scoped or paired with dynamic test evidence. + +## Findings + +### Finding 1: Clean checkout dependency resolution is broken + +Severity: CRITICAL + +The current `pubspec.yaml` ref cannot be resolved from the configured remote. This prevents `flutter pub get`, `flutter test`, `flutter analyze`, and the full agent workflow from running in a clean checkout. + +Required fix: + +- Publish the needed branch/commit to a remote, or +- point `pubspec.yaml` to an existing reviewed ref/tag/commit, or +- deliberately use a local path override only for local validation, never as CI evidence. + +### Finding 2: Local tests rely on `.dart_tool/package_config.json` + +Severity: HIGH + +The passing Real Unit tests used `--no-pub` and therefore relied on the existing local package config that points at `../../bitbox_flutter`. This is useful for local integration confidence, but it is not reproducible evidence for CI or another developer's machine. + +Required fix: + +- Restore reproducible package resolution first, then rerun the same tests without `--no-pub`. + +### Finding 3: Two different BitBox fakes exist + +Severity: MEDIUM + +Real Unit has `test/helper/fake_bitbox_credentials.dart`, while `bitbox_flutter` also exports `package:bitbox_flutter/testing.dart` with its own `FakeBitboxCredentials` and `SimulatedBitboxPlatform`. + +This is not automatically wrong because they sit at different seams: + +- Real Unit helper fake extends Real Unit `BitboxCredentials`. +- Plugin fake/simulator replaces `BitboxUsbPlatform.instance`. + +Risk: + +- Same class name and overlapping concepts can drift or confuse future tests. + +Recommended action: + +- Keep both only if the distinction is documented as "credentials-boundary fake" vs "platform-boundary fake". +- Prefer the plugin-level fake/simulator for lifecycle, pairing, channel-hash, disconnect, timeout, and platform-call tests. +- Keep the Real Unit helper fake only for high-level sign-pipeline tests where `is BitboxCredentials` is the behaviour under test. + +### Finding 4: bitbox-audit is too noisy without dynamic evidence + +Severity: MEDIUM + +`bitbox-audit` currently reports many `E1` criticals from localization output. The actual sign paths have ASCII guards and tests, but the audit job exits non-zero. + +Recommended action: + +- Feed dynamic test evidence into `bitbox-audit --test-results` where supported, or +- tune/suppress generated localization false positives in the audit tooling, not in product code, or +- add a repo-level audit note explaining why generated i18n strings are not sign payloads. + +## Current Confidence + +Local integration confidence: MEDIUM-HIGH. + +Reason: + +- Targeted BitBox tests pass locally. +- Plugin Dart and Go tests pass locally. +- Pairing mismatch, lifecycle loss, reconnect, sign queue timeout, KYC sign, and ASCII-safety behaviours are covered. + +CI/reproducibility confidence: LOW. + +Reason: + +- `pub get` fails from the declared dependency graph. +- The passing app tests require `--no-pub`. +- The dependency source differs across `pubspec.yaml`, `pubspec.lock`, and `.dart_tool/package_config.json`. + +## Safe Next Steps + +1. Make `bitbox_flutter` reproducible from a clean checkout. +2. Run `flutter pub get` without local overrides. +3. Rerun the BitBox test scope without `--no-pub`. +4. Run `flutter analyze`. +5. Re-run `bitbox-audit` and decide whether remaining `E1` findings are real payload risks or generated-code false positives. +6. Only after those pass should the full agent workflow continue beyond Gate 1.

Now the email step captures the cubit and re-provides it via BlocProvider.value into the pushed route. - KycStep.dfxApproval fell through to a blank grey Scaffold (no case in KycViewManager). Renders the pending/review page now; the KycState catch-all surfaces the state name instead of a blank screen. - Buy default amount (300 CHF) vanished when the brokerbot conversion stalled (the field only synced on loading→false). Pre-fill the controller so the amount shows from the first frame. - Buy failure state gains a `message` field, mirroring SellPaymentInfoFailure, for support/diagnostics (no behavioural routing change). - (a) getWalletStatus post-merge propagation race now auto-retries (bounded, injectable) instead of dead-ending on a manual retry. (b) Re-entrant merge resumption — SEE THE EXPLICIT CAVEAT BELOW: After an interrupted merge (email registered, auth-side merge done, but registerWallet not yet completed), restarting the app skipped the email step (mail is set) and dropped the user into fresh KYC instead of completing the merge. The merge was only ever detected via the one-shot JWT account-id delta, which cannot be re-derived once the auth merge has settled. This adds a restart-stable signal: parse `/v2/user.addresses`; if the active wallet is not yet registered, route into the verification page in re-entrant mode (initialMergeDetected) to finish registerWallet. !! UNVERIFIED ASSUMPTION (must be validated end-to-end before merge): the backend lists the wallet address under `/v2/user.addresses` ONLY AFTER registerWallet succeeds. If the address appears earlier (on the auth-side merge), the gate never fires and the gap persists; if it never appears, the gate loops. This was implemented from code analysis without a confirmed end-to-end merge run on a User-role account — verify before relying on it. Tests: buy cubit/state (incl. plain-403→unknown regression), kyc cubit (incl. KycWalletRegistrationRequired gate), email-verification cubit (incl. re-entrant initialMergeDetected path + bounded retry made injectable). --- .../service/dfx/models/user/dto/user_dto.dart | 13 ++++ lib/screens/buy/buy_page.dart | 7 +- .../buy_payment_info_cubit.dart | 25 +++++-- .../buy_payment_info_state.dart | 5 +- lib/screens/kyc/cubits/kyc/kyc_cubit.dart | 19 ++++++ lib/screens/kyc/cubits/kyc/kyc_state.dart | 10 +++ lib/screens/kyc/kyc_page_manager.dart | 21 +++++- .../kyc_email_verification_cubit.dart | 66 +++++++++++++++---- .../kyc/steps/email/kyc_email_page.dart | 13 +++- .../subpages/kyc_email_verification_page.dart | 27 ++++++-- .../buy_payment_info_state_test.dart | 11 +++- .../cubits/buy_payment_info_cubit_test.dart | 28 ++++++++ .../kyc/cubits/kyc/kyc_cubit_test.dart | 34 ++++++++++ .../kyc_email_verification_cubit_test.dart | 33 ++++++++++ 14 files changed, 282 insertions(+), 30 deletions(-) diff --git a/lib/packages/service/dfx/models/user/dto/user_dto.dart b/lib/packages/service/dfx/models/user/dto/user_dto.dart index 6113c0b68..39738b5a8 100644 --- a/lib/packages/service/dfx/models/user/dto/user_dto.dart +++ b/lib/packages/service/dfx/models/user/dto/user_dto.dart @@ -5,10 +5,19 @@ class UserDto { final UserKycDto kyc; final UserCapabilitiesDto capabilities; + /// Lowercased blockchain addresses currently associated with this user + /// account (the `addresses[].address` list from `/v2/user`).

Staging coverage gap. The branch flow is now staging -> develop -> main and fix PRs target staging, but the pull_request trigger only listed branches: [develop], so the BitBox gate gave no pre-merge signal on the staging lane. Add staging to the trigger. 2. Silent 24h hang on the self-hosted runner. Every flow job targets the self-hosted [self-hosted, macOS, arm64, bitbox] pool. With no runner online, an auto-triggered job (push: develop / schedule / labelled PR) does not fail fast -- GitHub queues it until the 24h max-queue limit cancels it, surfacing as a red check ~24h later (this is exactly how the summary job went red). Gate the auto-run paths on the repository variable BITBOX_RUNNER_ONLINE so the flow jobs skip cleanly until the runner is provisioned and the variable is set to 'true'. Manual workflow_dispatch is exempt -- the operator asserts the hardware is online. Document the variable as the final registration step in RUNNER.md. Fail-safe and reversible: the workflow has never run on develop yet, so default-off regresses nothing; flipping one repo variable restores the intended auto-run once the BitBox runner is online. --- .github/workflows/maestro-bitbox.yaml | 74 ++++++++++++++++++++------- .maestro/bitbox/RUNNER.md | 9 ++++ 2 files changed, 65 insertions(+), 18 deletions(-) diff --git a/.github/workflows/maestro-bitbox.yaml b/.github/workflows/maestro-bitbox.yaml index 5580e39dd..b553f745b 100644 --- a/.github/workflows/maestro-bitbox.yaml +++ b/.github/workflows/maestro-bitbox.yaml @@ -16,15 +16,33 @@ name: Tier 3 — Maestro BitBox flows # `.maestro/bitbox/RUNNER.md`. # # TRIGGER MODEL: -# * `pull_request: develop` with the `tier3:bitbox` label gate -- the -# PR-gate subset (M-1 / M-3 / M-5 / M-6) runs.
