Summary

  • recover persisted SDK wallets only on the network encoded by their stored wallet ID, preventing mainnet/testnet clones
  • select testnet before runtime startup when reinstall or legacy migration leaves only testnet wallets
  • serialize legacy DashSync mnemonic migration and cleanup so a removed seed cannot be re-imported concurrently
  • make Wallets → Remove delete the selected seed’s matching legacy mnemonic and both SDK network variants while leaving unrelated wallets intact
  • scope ordinary recovery wipe to legacy accounts matching its single authorized SDK seed; support-assisted Delete All removes all legacy mnemonic accounts
  • keep debug reset and screenshot replacement isolated from legacy cleanup
  • use count-free Delete All copy because legacy-only seeds may not appear in SDK inventory
  • add focused recovery, cleanup, authorization-scope, and routing regression tests and update migration documentation

Dependency

Stacked on #1018. Merge order: #1014#1017#1018 → this PR. #1019 is closed and is not part of this branch history. After the preceding PRs merge, retarget this PR to develop.

Review follow-up

This update addresses the authorization-scope concern: .recoveryFlow now fails closed unless strict SDK inventory contains exactly one normalized logical seed, removes only matching legacy mnemonic accounts, and rechecks SDK inventory after the shared migration queue barrier before SDK deletion. .confirmedDeleteAll remains the only production authorization that removes every legacy mnemonic account.

Legacy cleanup intentionally remains before SDK deletion so migration cannot recreate the seed between SDK deletion and cleanup. The operation is idempotent and retry-based; no rollback layer was added.

Verification

  • git diff --check
  • static authorization and destructive call-site audit
  • compile-ready focused tests added
  • no Xcode build or test run for this change, per request
  • manual restart, rebuild, and uninstall/reinstall smoke testing remains required

Review Change Stack

📝 Walkthrough

Walkthrough

This change adds strict persisted-wallet inventory, explicit wipe authorization, legacy mnemonic cleanup, network-aware recovery, recovery-phrase selection, logical-wallet deletion, and updated destructive-action flows across the wallet UI.

Changes

Wallet recovery and deletion

Layer / File(s) Summary
Strict wallet inventory and migration
DASHSYNC_KEY_MIGRATION.md, DashWallet/Sources/Infrastructure/SwiftDashSDK/*, DashWalletTests/WalletWipeSerialExecutorTests.swift
Migration remains non-destructive by default. Strict inventory reads now fail on unexpected Keychain errors. Recovery filters entries by network and validates restored wallet IDs.
Wipe authorization and logical deletion
DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKWalletWiper.swift, DashWallet/Sources/UI/Setup/RecoverWallet/*, DashWallet/Sources/UI/Setup/SecureWallet/Seed/*
Wipes use explicit authorization modes. Legacy mnemonic cleanup occurs before applicable SDK deletion. Phrase matching and logical-wallet deletion now validate all required data.
Recovery phrase inventory and selection
DashWallet/Sources/UI/Menu/Security/RecoveryPhraseFlow.swift, DashWallet/Sources/UI/Setup/WalletRecovery/KeychainWalletRecoveryCoordinator.swift, DashWallet.xcodeproj/project.pbxproj, DashWallet/en.lproj/Localizable.strings, DashWalletTests/WalletWipeSerialExecutorTests.swift
Recovery phrase loading inventories wallets, groups mirrored networks, selects direct or picker routes, and supports retry and cancellation states.
Security and wallet-screen integration
DashWallet/Sources/UI/Menu/Security/*
Security and wallet screens expose recovery-phrase actions, picker navigation, debug copying, and persisted-inventory-based wallet removal.
Destructive entry-point wiring
DashWallet/Sources/UI/LockScreen/*, DashWallet/Sources/UI/Main/*, DashWallet/Sources/UI/RootNavigation/*, DashWallet/Sources/UI/Setup/RecoverWallet/*
Lock-screen, onboarding, root navigation, and recovery flows use explicit wipe authorization and report multi-wallet or testnet shortcut restrictions.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 365bb

The recovery flow can currently hide all valid wallets when one stored wallet record is malformed or unrecognized, potentially preventing users from recovering wallets they can still identify. This should be fixed or explicitly accepted before merge.

Consider splitting this file by responsibility.

This file combines several responsibilities: network mapping, descriptor models, keychain/SDK inventory reading (RecoveryPhraseInventory), the flow view model, the picker view model, the SwiftUI picker screen, and UIKit navigation (RecoveryPhraseNavigation). The repository guideline requires "One file = one responsibility". Splitting the inventory and model types away from the view and navigation layers also lets the inventory logic be unit-tested without importing SwiftUI.

A minimal split: RecoveryPhraseInventory.swift (lines 28-218), RecoveryPhraseFlowViewModel.swift (lines 220-441), and RecoveryPhrasePickerScreen.swift (lines 443-617).

As per coding guidelines: "One file = one responsibility — a 'coordinator' that accumulates published UI counters, storage wipes, and money movement gets split."

Handle an empty phrase in release builds too.

NSParameterAssert is compiled out when NS_BLOCK_ASSERTIONS is defined. In a release build an empty argument leaves existingSeedPhrase empty, and getOrCreateNewWallet then generates a new seed instead of previewing the requested one. The fallback is safe, but the caller receives no signal.

Review follow-up on the remaining non-functional suggestions: we are not splitting RecoveryPhraseFlow or replacing the short-lived deletion tuple with new types in this series, because those changes add file/project churn without changing behavior. The existing-seed initializer is reached only after a strict non-empty mnemonic read and validation, so the empty-input fallback is not reachable through this flow. Diagnostic logging, localization propagation, and style-only lint cleanup can follow the normal project workflow or actual CI output; they are not being treated as functional blockers here.

This is the heaviest PR in the chain, and the one I'd hold longest.

The main point is policy, not code: this deletes legacy DashSync seed material

The PR rewrites a documented hard invariant. Before:

NEVER deletes from org.dashfoundation.dash. DashSync entries are read-only here forever; they are preserved indefinitely as belt-and-suspenders rollback source.

After: read-only "except when an explicit production Remove/Delete All operation deletes wallet mnemonic accounts".

As far as I know the standing rule is the opposite — legacy seed material is kept, not auto-mounted, and purge/move fixes are off the table. That's a decision above the level of a code review, and it needs explicit sign-off before this merges regardless of how well the implementation reads. Everything below assumes the policy question is answered yes.

Legacy is deleted before the operation that can fail

performWipe (SwiftDashSDKWalletWiper.swift:220) runs the legacy cleanup first and the SDK deletion after. deleteLogicalWallet does the same — removeLegacyMnemonicAccounts at line 565, SDK deletion after.

If the SDK deletion then fails, the wipe reports failure and offers Retry, but the rollback source is already gone for good. The exact scenario the legacy material exists for — a partially failed wipe — is the one where it has already been destroyed. The order needs to be inverted: legacy cleanup only after the SDK deletion is confirmed complete.

The authorization doesn't cover what gets deleted

removeAllLegacyMnemonicAccounts() removes every WALLET_MNEMONIC_KEY_* account. For .recoveryFlow, the authorization from #1014 is a proof that the typed phrase matches every stored SDK mnemonic. Legacy accounts that never migrated (a deferred failure, an unknown chain) aren't covered by that proof, and get deleted anyway. The two sets aren't shown to be equal.

Automatic testnet switch with no build gate

WalletEnvironment.switchToNetwork has no #if DASH_TESTNET guard:

guard kind != networkKind else { return true }
guard kind != .devnet else { return false }

It also clears the DashPay username mirror as a side effect. Two new paths can now reach it — keepWallets in the reinstall coordinator and selectSolePersistedNetworkIfNeeded in the runtime — so a production install can be flipped to testnet with no user consent. The manual network switcher is gated by build config; these automatic paths aren't.

Separately: the refresh returns right after selectSolePersistedNetworkIfNeeded succeeds. Please confirm the posted DWCurrentNetworkDidChange actually re-drives the runtime, otherwise startup stalls on that branch.

Unattended destructive call at launch

In recoverPersistedWallet, the id-mismatch branch used to be additive (storeMnemonic). It's now:

try? handles.manager.deleteWallet(walletId: created.walletId)

deleteWallet removes the SwiftData rows and the Keychain mnemonic, per its own docstring. Meanwhile entries are already filtered through recoverablePersistedMnemonics(for:), which resolves each id against that exact network — so the mismatch should be unreachable by construction. That buys nothing and adds an unattended destructive call on every launch. Logging and skipping would be enough.

Remove quietly grew its blast radius

Previously a Wallets-row Remove deleted one walletId. deleteLogicalWallet(mnemonic:) now deletes both network ids for that seed plus the legacy account. The screen only lists the current network, and the copy doesn't say the testnet twin and the legacy backup go with it. It also blurs the Remove/Delete All boundary that #1017 just drew.

Latent deadlock on the shared queue

legacyWalletQueue now serves both performMigration — which blocks its own queue on a DispatchSemaphore waiting for a Task { @MainActor } in createWalletOnHost — and removeAllLegacyMnemonicAccounts() via .sync.

There's no cycle today: every .sync caller arrives on the wiper's queue and the main thread stays free. But any future main-thread caller deadlocks the app instantly. Worth a dispatchPrecondition(condition: .notOnQueue(.main)), or making it async like its removeLegacyMnemonicAccounts sibling.

Minor

  • CodeRabbit is right that the catch in presentReinstallKeepOrDeleteChoice swallows error with no log, unlike the sibling coordinator.
  • The PR body states there was no Xcode build or test run for this change, so it hasn't been compiled at all.

I'm requesting changes primarily on the ordering and authorization-scope points. The legacy-deletion policy itself isn't something I can sign off on here — that needs a decision from the CTO before this branch is worth polishing further.

@romchornyi On the legacy-before-SDK ordering: this is intentional and I do not think we should invert it.

The confirmed bug was resurrection across restart/reinstall: the SDK copy was deleted while WALLET_MNEMONIC_KEY_* remained, then the migration ledger disappeared with UserDefaults on uninstall and the migrator imported that legacy seed again. There is also an in-process race where migration can read/import the legacy seed between SDK deletion and later legacy cleanup.

Migration and cleanup therefore share legacyWalletQueue. With the current ordering:

  • if migration started first, cleanup waits for that import to finish, removes the legacy source, and the following SDK deletion removes the imported copy;
  • if cleanup wins, the later migration finds no mnemonic account to import.

Reversing the order to SDK → legacy would reopen the exact resurrection window this PR exists to close.

For an explicitly authorized production Remove/Delete All, the legacy mnemonic is no longer treated as a rollback backup; it is wallet material the user has instructed us to retire permanently. The deletion contract is retry/convergence, not an atomic rollback of already completed wallet deletions. PlatformWalletManager.deleteWallet removes the SDK mnemonic last, so a failure before a wallet deletion completes leaves that SDK mnemonic available for Retry. A wallet whose deletion completed successfully remains deleted even if a later wallet/network fails, while the UI reports the overall operation as incomplete and Retry handles what remains.

Given that product semantics, adding a tombstone/rollback transaction only to preserve the legacy seed would add complexity and weaken the resurrection guarantee. I propose keeping legacy → SDK and documenting this intentional no-rollback behavior. The separate authorization-scope concern about which legacy accounts may be deleted still needs to be addressed independently.

Updated and rebased directly onto #1018; #1019 is no longer in this branch history.

The authorization-scope issue is now fixed with a minimal split:

  • ordinary .recoveryFlow requires exactly one normalized SDK seed and removes only matching legacy mnemonic accounts;
  • SDK inventory is rechecked after the shared migration/cleanup queue barrier before SDK deletion;
  • support-assisted .confirmedDeleteAll remains the only production path that removes every legacy mnemonic account;
  • debug reset and screenshot replacement still preserve legacy data;
  • Delete All warnings no longer show an SDK-only count that could omit legacy-only seeds.

Legacy-first ordering is intentionally unchanged to prevent migration resurrection; the flow remains idempotent and retry-based. git diff --check passes. No Xcode build/test run, per the agreed workflow.

@romchornyi please take another look when you have a moment.

Testnet auto-switch without build gate

WalletEnvironment.switchToNetwork doesn't have an #if DASH_TESTNET guard, and two new paths (keepWallets in the reinstall coordinator, selectSolePersistedNetworkIfNeeded in the runtime) can now reach it automatically. That means a production install could get flipped to testnet with no user consent and no build-level protection, unlike the manual network switcher. This wasn't addressed in the latest push — could you either add the guard or explain why it's safe without one?

Remove's blast radius isn't communicated in the UI

deleteLogicalWallet(mnemonic:) now deletes both network IDs for a seed plus the legacy account, but the Wallets screen only lists the current network and the copy still reads like a single-wallet delete. Users tapping Remove on what looks like one wallet won't know the testnet twin and legacy backup are going with it. Worth updating the confirmation copy before merge.

Latent deadlock on legacyWalletQueue

No cycle exists today since every .sync caller arrives on the wiper's queue, but performMigration blocks that queue on a semaphore waiting for a main-actor task, while removeAllLegacyMnemonicAccounts() also calls .sync on it. Any future main-thread caller would deadlock the app. A dispatchPrecondition(condition: .notOnQueue(.main)) or making it async (like removeLegacyMnemonicAccounts) would make this safe by construction rather than by convention.

Thanks, I agree that the Wallets-row Remove copy should state the full logical-wallet scope. I am updating it to say that the wallet is removed from this device on every network where it is stored, while other wallets remain unaffected. The legacy entry is an implementation-level duplicate of the same seed, so the UI does not present it as a separate wallet.

On the automatic testnet selection, I propose keeping the current behavior. The premise that manual testnet switching is build-gated does not hold for the current base: SettingsScreen already exposes Mainnet/Testnet switching without a DASH_TESTNET conditional. The automatic path is narrower than that existing manual capability: it runs only when strict persisted inventory resolves to exactly one network and that network differs from the default/current one. This is required for a testnet-only wallet surviving reinstall, or produced by legacy migration, to start instead of leaving the runtime stopped on default mainnet. The user also explicitly chooses Keep Wallets in the reinstall path. Clearing the username mirror is the existing required side effect of any network switch and is repopulated from the selected network.

On legacyWalletQueue, I agree that a future main-thread caller of the synchronous cleanup API would be invalid, but there is no reachable deadlock in this PR. Both synchronous cleanup methods are called only by the wallet wiper background queue; targeted Remove uses the async continuation API. A dispatchPrecondition would turn hypothetical future misuse into a crash, while converting the full wipe boundary to async would broaden this security-sensitive diff without changing current behavior. The API documentation already states its off-main calling contract, so I propose leaving this as-is unless a real main-thread call site is introduced.
