`@packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt`:
- Line 328: Guard the shielded tip account lookup in DashPayTabScreen by
computing shieldedTipAccountIndex with remember(tipManager,
identity.identityIndex), wrapping the lookup in runCatching, and retaining only
a non-null result. Render ShieldedTipSheet only when that remembered result
exists, instead of invoking shieldedTipAccountIndex directly during composition.
In
`@packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/ShieldedTipSheet.kt`:
- Line 105: Update the ShieldedTipSheet send-error handling around submitted so
it resets submitted for every exception except
DashSdkError.PlatformWallet.ShieldedSpendUnconfirmed, preserving the locked
state only for that specific unconfirmed-spend error.
In `@packages/rs-platform-wallet/src/wallet/platform_wallet.rs`:
- Line 927: Update the account collection in the seedless rebind flow around
discovered_tip_accounts and bind_shielded_from_persisted so discovery-derived
accounts without persisted FVK rows in start.shielded.viewing_keys are skipped.
Preserve fallback behavior for explicitly required accounts and continue
rebinding accounts that have persisted rows.
In
`@packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/DashPayProfileView.swift`:
- Line 24: Update the shieldedNotes `@Query` in DashPayProfileView to initialize
with PersistentShieldedNote.unspentPredicate(walletId:) using
identity.wallet?.walletId, so the query observes only this identity’s unspent
wallet notes; retain the existing accountIndex and isSpent filtering in
tipBalance.
In
`@packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/SearchWalletsForIdentitiesView.swift`:
- Line 366: Separate the throwing bindShielded call in discoverIdentities from
the discovery error handling so a binding failure does not discard the already
returned found result. Preserve found.count when reporting the failure, and
continue loading the preview for binding errors.

Final validation — Phase 2 only (queue backlog)
All four Phase-2 findings are supported by the exact-head source. A local Foundation reproducer confirmed the amount-parsing mismatch; source tracing confirmed the Android submission-state loss, native panic-containment gap, and missing durability-boundary test coverage. Under the supplied severity policy, these non-consensus correctness and test-coverage issues are suggestions rather than blockers; full mobile and Rust suites were not rerun during verification.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/DashPayTabView.swift:1054-1059: Reject partially parsed tip amounts before confirmation
Decimal(string:locale:) does not require the entire input to be numeric. Running the exact conversion and precision checks locally confirmed that "1,5" parses as 1 and passes validation as 100,000,000,000 credits; "1abc" also passes. A comma decimal separator is reachable through decimalPad in applicable locales. The confirmation displays the original amount string, while sendShieldedTip receives the parsed credits, so a user can confirm "1,5 DASH" but send 1 DASH. Validate the complete input using an explicit locale policy, reject unsupported separators rather than silently truncating, and render the confirmation from the validated numeric amount.

ModalBottomSheet can be dismissed while a tip is being sent, and its dismissal removes ShieldedTipSheet from composition. That discards the remember-backed submitted flag and cancels the sheet's coroutine scope. PlatformWalletManager.sendShieldedTip runs the blocking JNI call through TeardownGate on Dispatchers.IO; cancellation does not stop an already-running native call from proving and broadcasting. Reopening the sheet therefore creates submitted=false and allows another payment without knowing the first payment's outcome. Note reservations prevent reuse of the same inputs, not a second payment funded by other available notes. Hoist the in-flight and uncertain-outcome state outside the dismissible composable, and prevent dismissal during the native send, including gesture-driven sheet hiding.

- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:2747-2768: Contain worker panics inside the new shielded-tip C export
The new extern "C" export invokes block_on_worker without catch_spend_panic. block_on_worker calls expect on its spawned task's JoinHandle result, so a worker panic causes another panic on the calling thread. Letting that unwind reach the non-unwinding C boundary aborts the process. The Android JNI guard surrounds the call to this export and is outside that boundary, so it cannot catch the panic. Android's configured profiles retain unwinding, making the existing catch_spend_panic helper applicable. Wrap the worker call and result mapping inside that helper to return ErrorShieldedSpendUnconfirmed and preserve the conservative no-retry contract. This does not make panics recoverable under the iOS panic=abort profiles.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/viewing_key_bind_tests.rs:871-874: Exercise flush failures before returning a publishable tip address
The preparation test uses CapturingPersistence, whose flush implementation always returns Ok(()) and does not record calls. The test checks captured viewing-key changesets and deterministic addresses, but would still pass if prepare_shielded_tip_address stopped flushing before returning. That leaves the new API's publication durability guarantee unprotected. Add a persistence double that records store/flush ordering and can fail flush. Assert that a flush failure returns PlatformWalletError::Persistence instead of an address, then verify that retrying after persistence recovers succeeds even though the first attempt already bound the account in memory.

Review summary
Verdict: nothing consensus-breaking, and the core design holds (dedicated ZIP-32 account per identity, keep/set/remove merge, FFI/JNI parity, additive migrations). Not merge-ready as it stands: three host-side defects should be fixed first, and no Rust, Swift or Kotlin CI has run on this branch.
Fix before merge (inline):
- Kotlin tip sheet: the send lock is sheet-local and the sheet can be dismissed mid-send, so a landed spend can be re-sent (
DashPayTabScreen.kt). - iOS "Total Shielded Balance" still includes tip-account notes while four other surfaces exclude them (
CoreContentView.swift). prepare_shielded_tip_addresson an unbound wallet binds only the tip account; reachable on Android via the best-effort launch bind (tips.rs).
Should fix (inline): Remove on an unsupported address field aborts the whole profile edit (profile.rs); identity discovery reports failure when only the follow-up shielded bind failed, on both platforms, and the Swift view dumps preview keys in that case; iOS tip balance and spend source use index 0's tip account for identities without a recoverable index (DashPayProfileView.swift); SHIELDED_TIPS.md claims a library-level balance exclusion that only the example apps implement.
Minor / forward-looking (inline): dashpay_profiles format stamp with no format-0 decoder, and SCHEMA.md not updated; serde(default) is inert under bincode; DashSchemaV4 registered from live types rather than frozen; the storage-explorer check is a substring grep.
Process: every Rust, Swift and Kotlin job was skipped by the fork trust policy, so the only test evidence is the local runs in the description. Please trigger the workflows, or push the branch to the main repo, before merge.
Checked and fine: the contract change is correctly scoped (optional 43-byte field at position 7; the new Drive test proves only protocol 14 accepts it); rebasing the v2 contract bytes is safe because all 51 testnet evonodes run 4.1.x, so protocol 14 is live nowhere; fee and root-hash pins are consistent with historical pins untouched; the profile data trigger correctly leaves the shielded field alone; the DPNS decoding fix; independent ZIP-32 accounts with IVK/OVK isolation; the property merge cannot drop a field; FFI and JNI signatures and presence flags on both platforms; SQLite, Room and SwiftData migrations are additive and tested against pre-populated old-schema stores.
Findings verified against the code at 75e1592. Review assisted by Claude Code.

Fix before merge: a landed tip can be sent twice.
The send lock (busy / submitted) is remember state inside ShieldedTipSheet, and this onDismissRequest is unconditional. If the user swipes the sheet away or presses back during the ~30 s proof + broadcast, rememberCoroutineScope is cancelled but the JNI call keeps running on Dispatchers.IO (TeardownGate.op), so the spend can still land. Reopening gives a fresh sheet with no lock, and the "ambiguous outcomes remain locked" guarantee in ShieldedTipSheet.kt is lost: the same tip can be re-reviewed and sent again.
Suggest hoisting busy / submitted to this parent (or a ViewModel) and ignoring dismiss requests while a send is in flight.

Fix before merge: one balance surface still includes tip notes.
This exclusion was added here and on three other surfaces (SendTransactionView.swift:496, WalletDetailView.swift:1050, CreateIdentityView.swift:1837), but totalUnspentCredits at lines 1529-1533 (rendered as "Total Shielded Balance" at line 577) still sums every unspent note:
allNotes.lazy
.filter { !$0.isSpent && walletIds.contains($0.walletId) }
.reduce(UInt64(0)) { $0 &+ $1.value }A user with 1 DASH in account 0 and 5 DASH of received tips sees 6 DASH on the shielded summary and 1 DASH on the wallet card and send screen, with no explanation, and the 6 DASH figure is not spendable through any ordinary path because every app spend targets account 0 (SendViewModel.swift). Apply the same isShieldedTipAccount filter there.

Fix before merge: preparing on an unbound wallet binds only the tip account.
When the wallet is not yet bound, shielded_account_indices() returns an empty list, so this call binds {tip} alone. bind_shielded only unions discovered and persisted tip accounts (platform_wallet.rs:798-815), never account 0. Afterwards is_shielded_bound() is true, but derive_spend_keyset(seed, 0) fails with "account 0 not bound" and shielded_balances() omits account 0 until the host rebinds.
This is reachable in KotlinExampleApp: the launch bind in AppContainer.rebindWalletScopedServices is explicitly best-effort (a declined biometric leaves the wallet unbound), and the "Use this wallet's dedicated tip account" button is gated on Sdk.hasShielded(), not on a live bind. It self-heals on the next launch, but within the session account 0 is invisible and unspendable.
Suggest returning ShieldedNotBound when the current account set is empty (or including account 0 explicitly), plus a test for the unbound + correct-seed path. The existing should_restore_tip_account_from_identity_discovery_and_register_for_sync only covers unbound + wrong seed.

Should fix: Remove on a field the network lacks aborts the whole profile edit.
Removing a field the connected contract cannot have is a no-op, but this branch fires for Remove as well as Set, so the entire create/update (display name, avatar, everything) is rejected with "does not support {field} yet". A host that expresses "address empty" as Remove rather than Keep cannot edit its profile on a network still on the older DashPay contract.
Only Set needs the activation check. Both example apps happen to send Keep for an empty unpublished field, so this is an API hazard for other hosts rather than a live app bug.

Should fix: this rebind bypasses ShieldedService and reports its failure as a discovery failure.
Two problems:
- It calls
bindShieldedwithoutconfigureShielded. The wrapper's guard is only the managerisConfiguredflag (PlatformWalletManagerShieldedSync.swift:190), so the call reaches Rust, which returns "shielded support not configured" if the shielded DB was never configured. The onlyconfigureShieldedcall sites are the best-effortShieldedService.bind/bindEngineat launch, so if those did not run (no wallet at launch, mid network switch, wallet imported this session) a fully successful discovery is surfaced to the user as an error. - It uses the default
accounts: [0]rather thanShieldedService.boundAccounts, and the service mirror (isBound,boundAccounts,addressesByAccount) is never updated, so it silently diverges from the engine.
Suggest routing this through ShieldedService, which owns configure + bind + mirror, and treating a bind failure as a non-fatal warning the way the Kotlin AppContainer does.

Doc overclaims the library. This sentence is only true of the example apps. In the library, is_shielded_tip_account is used solely in the bind paths (to include persisted tip accounts), PlatformWallet::shielded_balances() iterates every bound account with no tip filter, and no spend-selection code references it. A third-party host using shielded_balances() or the FFI directly will see tip funds folded into the aggregate.
Either implement the exclusion in the library (a filtered balance accessor at minimum) or reword this to say the separation is a host responsibility.

Forward-looking gap. Every writer now stamps profile_format = 1 and V008 defaults pre-existing rows to 0, but nothing in the crate decodes a format-0 dashpay_profiles row: identity_profile_encoding.rs only exposes decode_identity for the identities table and LegacyProfile is private. Harmless today because the only reader of profile_blob is a test, but when the load() TODO grows a production reader, a V7-written row will fail (or misparse) unless a decode_profile(payload, format) twin exists. Worth adding now while the legacy shape is fresh.
Also, SCHEMA.md does not mention entry_format or profile_format.

serde(default) has no effect for the bincode blobs these fields are stored in: bincode's serde path deserializes structs as fixed-arity tuples, so a six-field legacy blob is never "short" and the default is never taken (which is presumably why LegacyProfile exists in the storage crate). Keeping the attribute suggests self-healing decoding that does not exist. Either drop it or add a comment that it only serves JSON surfaces.

Forward-looking: V4 is not actually frozen. DashSchemaV4 is now a released, migrated-from version, but it is registered from the live model types, unlike V1 to V3 which use frozen DashSchemaV1.* copies. This PR is safe (it adds an entity; no existing model gained a stored property, so V4's checksum is unchanged), but the next stored property added to any model mutates V4's checksum in place, and a store written by a V4 binary will then match no registered schema and fail to open (Cocoa 134504) instead of migrating. The V3 comment in this file states the rule: freeze the old shape, add a version, add a stage. This PR is the natural place to freeze V4.

The extraction fix here is a real improvement (at the merge base the old scope yielded only two models; this yields all 36). But the per-model checks at lines 55, 68 and 80 are bare substring greps (grep -q "$model"), so any model whose name is a prefix of another is unfalsifiable. That weakness predates this PR (PersistentToken / PersistentTokenBalance, PersistentWallet / PersistentWalletManagerMetadata), and the new PersistentDashpayPaymentAddresses adds another instance: deleting PersistentDashpayPayment's list or detail view would now pass. A word-boundary match such as grep -qE "\b$model\b" fixes all of them.

Let a DashPay user publish a reusable shielded tip address and receive payments by username. Wallet-generated addresses use a dedicated ZIP-32 account per identity, separating tip viewing keys from ordinary wallet activity. Users can also publish an externally generated Orchard address.
This follows the transparent profile-address work in #4380 and the 43-byte format in dashpay/dips#188. Contract, wallet, persistence, native bindings, and Swift/Kotlin example flows land together in this PR.
What was done?
profile.shieldedAddressto DashPay contract v2 at position 7: 43 raw bytes, including the full diversifier. Consensus enforces the byte length; clients validate Orchard decoding. Extend the protocol 13→14 migration/cache tests and update only the applicable fee/root fixtures.0x40000000 + index. Preparation verifies the seed, binds viewing keys, and flushes persistence before returning an address. Identity discovery reconstructs the account without relying on the current profile; retired tip accounts keep scanning. Ordinary balance/spending choices exclude tip accounts, with explicit access to tip funds.How Has This Been Tested?
Local macOS builds and targeted validation:
StateFlow.valuecomposition finding inSyncStatusScreen.kt:215.git diff --checkpasses. Storage explorer coverage passes for all 36 models, with a negative fixture verifying inherited-model omissions are detected.GitHub skips Rust and mobile runner jobs for this fork under the existing workflow trust policy; the results above are local validation.
Not exercised: a live funded network tip transaction, Android NDK/native
.sobuild, or Android device/instrumented execution. Full network end-to-end validation remains a release validation step.Breaking Changes
