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 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.

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 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).

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.

localization strings are not automatically EIP-712 payload fields.
