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.

- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt:330-333: Preserve the submission guard when dismissing an in-flight tip
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.
In `packages/rs-platform-wallet-ffi/src/shielded_send.rs`:
- [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.
In `packages/rs-platform-wallet/src/wallet/shielded/viewing_key_bind_tests.rs`:
- [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.

Final validation — Phase 2 only (queue backlog)
All four prior findings are fixed at the current head. Source verification confirms two remaining mobile correctness issues, a panic-containment gap in the new non-spending C exports, and a regression-test coverage gap; these are suggestions under the supplied non-consensus severity policy. The incremental diff passes git diff --check; this verification did not rerun test suites or exercise either mobile app.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/DashPayTabView.swift:1085-1086: Retain uncertain Swift tip submissions across sheet dismissal
After sendShieldedTip throws shieldedSpendUnconfirmed, the catch sets the sheet-local submitted flag, but defer clears busy. Both dismissal controls then permit closing the sheet, and reopening either tip entry point creates a fresh submission guard even though the previous payment remains unresolved. The native reservation protects only the selected input notes, not the payment intent, so other sufficient notes can fund an unintended second payment. Keep the unresolved submission state in a network/wallet-scoped owner shared by both entry points, retain the warning across reopening, and require reconciliation before allowing a retry. Add a dismissal/reopening regression for an unconfirmed result.
In `packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt`:
- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt:329-330: Resolve Kotlin tip accounts from real identity derivation metadata
This lookup accepts Room's non-null identityIndex even when its zero value is only a placeholder. onPersistIdentityUpsert independently attaches the wallet link while preserving existing?.identityIndex ?: 0 if native derivation metadata is absent. That state is reachable when network/loading.rs loads an already-observed identity: it assigns managed.wallet_id without filling identity_index, and subsequent key persistence includes the identity snapshot. The lookup therefore succeeds with identity zero's tip account. If the user selects the dedicated-account checkbox and that account contains funds, the sheet can spend another identity's tip pool; DashPayProfileScreen derives its displayed balance from the same assumption. Validate the native optional identity index and wallet association before enabling dedicated-account display or spending, and reject missing metadata rather than interpreting it as zero.
In `packages/rs-platform-wallet-ffi/src/shielded_send.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:2691-2694: Contain worker panics in the non-spending tip C exports
The new resolve export calls block_on_worker without a C-side panic guard, and platform_wallet_manager_prepare_shielded_tip_address does the same at lines 2660–2664. On unwind-enabled builds, block_on_worker re-panics when its worker returns a JoinError. That unwind reaches the extern "C" boundary and aborts the process before the outer JNI guard can translate it into an exception. Wrap the fallible work in these two new exports with a C-side catch_unwind boundary, map the panic to an appropriate non-spending error, and preserve the zeroed outputs on failure. This is conditional panic containment, not evidence that ordinary invalid input triggers a panic.
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:2260-2268: Exercise the real C export in the panic regression test
This test constructs its own catch_spend_panic/block_on_worker stack instead of calling platform_wallet_manager_send_shielded_tip. The production export is now correctly guarded, but removing that guard would leave this regression green. Add an entry-point-level test with an injected worker failure so the test protects the boundary wiring that fixed the original defect. Run the assertion in a subprocess if necessary, allowing an unguarded extern "C" abort to fail the test without terminating the entire suite.
Resolves the conflicts with the 99 commits v4.2-dev gained since the branch point and adapts the branch to them: - platform-wallet-storage: the profile-encoding migration is renumbered V008 -> V019 (v4.2-dev already ships V008-V018). The stamp columns now DEFAULT 1 and the migration marks the rows it finds 0, so only pre-V019 rows are ever decoded as legacy. The identities writer and both readers on the hard-delete schema (dashpay#4496) stamp and dispatch on `entry_format`; the dashpay writer stamps `profile_format`. The migrated-database walk moved to tests/sqlite_profile_address_encoding.rs (the crate's retired-table-name scan covers src/), backed by test-only legacy encoders. SCHEMA.md and the migration fingerprints updated. - swift-sdk: V4 is frozen through scripts/freeze_schema_models.py (FREEZES row at 787cac0) instead of a hand-written copy; the dash-v5.store fixture is written by this build; the migration tests join the fixture-based suite from dashpay#4644. - drive / drive-abci: PV14 fee and root-hash pins recomputed for DashPay contract v2 on top of the contract version item (dashpay#4749). - platform-wallet: base's re-seeded shield regression fixture kept; both sides' viewing-key bind tests kept; the FFI account-indices exports re-appended after base's new test modules.

…tip send guard - platform-wallet-ffi: `platform_wallet_manager_prepare_shielded_tip_address` and `platform_wallet_resolve_shielded_tip` run their worker call inside `catch_query_panic` (ErrorWalletOperation, retryable); the raw output writes happen only on success so the zeroed buffers survive a panic. A test-only fault injected inside the worker future drives the three real `extern "C"` tip entry points, so removing a guard at a call site fails `exported_tip_entry_points_contain_a_worker_panic`. - SwiftExampleApp: `ShieldedTipSubmissions`, an app-owned per network and wallet guard, keeps an in-flight or uncertain tip send locked across sheet dismissal and both entry points (parity with the Kotlin app); tests. - KotlinExampleApp: the tip account is derived from the live identity's optional derivation index (`ManagedPlatformWallet.identityIndex`), not Room's non-null `identityIndex` whose 0 is a placeholder that aliases identity 0's tip pool.

Move identityIndex orchestration into Rust.
ManagedPlatformWallet.identityIndex calls three separate JNI entry points and manages the native handle in Kotlin. The Kotlin SDK rule requires thin JNI wrappers and prohibits stitching existing Rust calls in Kotlin. Add one Rust FFI operation, exposed through one Kotlin wrapper, that resolves the optional index and destroys the managed-identity handle on every path. Preserve the current not-found and index-less null results.

Persist unresolved submissions across process restarts.
wallets is process-local, so relaunching the app recreates a .ready guard and calls sendShieldedTip again. Native redrive state preserves the original transition and reservations, but reserve_unspent_notes excludes only those reserved notes. If another eligible note remains, the retry can submit a second irreversible tip while the original may still confirm.
Persist a pending or uncertain marker before sending. Clear it only after a confirmed failure or shielded-activity reconciliation.

Re-review — Final validation — Phase 2 only (queue backlog)
Seven prior findings are fixed, but the identity-index finding remains valid because mobile restoration converts missing derivation metadata into index zero. Six deduplicated suggestions remain; under the supplied severity policy, these client-side correctness, persistence, performance, and test-coverage issues are non-blocking. Independent validation passed the five schema-generator tests, storage-explorer coverage for all 36 models, and git diff --check; Rust and mobile runtime suites were not rerun.

- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt:332-340: Invalidate the previous tip account when switching identities
Changing produceState's keys restarts its producer but does not reset its remembered value to initialValue. The active-identity branch remains in composition when selection changes, so identity A's successful account result remains available while identity B's asynchronous identityIndex lookup runs. The button and sheet consume that untagged result alongside the current wallet selection. If a dedicated-account send is confirmed during that window, ShieldedTipSheet captures the stale index as sendAccount; the Rust send API accepts an account rather than a sender identity and does not reject another bound account merely because it belongs to a different identity. Wrap the state in a composition key scoped to network, wallet, and identity, or return the lookup identity with the result and reject mismatches. Add a regression that pauses B's lookup after switching from A and verifies that A's account cannot be used.
- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt:336-339: Resolve Kotlin tip accounts from real identity derivation metadata
(existing thread: https://github.com/dashpay/platform/pull/4616#discussion_r3969291944)
The live getter fixes the immediate Room-placeholder lookup, but the same alias returns after restart. PlatformWalletPersistenceHandler.onPersistIdentityUpsert retains existing?.identityIndex ?: 0 when the native index is absent while independently retaining the wallet association. buildIdentityRestoreData forwards that value, and Rust's build_wallet_identity_bucket constructs ManagedIdentity::new(identity, spec.identity_index), turning the placeholder into Some(0). This input is reachable: load_identity_by_index_inner attaches wallet_id to an already-observed identity without assigning identity_index. Consequently, the getter and DashPayProfileScreen can select identity zero's tip account for a different identity after restoration; the native preparation and discovery helpers also trust the fabricated index. Swift has the equivalent loss through persistIdentities and buildIdentityRestoreBuffer. Preserve index presence through the mobile stores and restore representation, or recover and verify the derivation index before enabling dedicated-account operations. Do not treat ambiguous legacy zero values as verified index zero. Add a persist/reload regression distinguishing an absent index from genuine index zero.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/ShieldedTipSubmission.swift:10-18: Persist unresolved tip submissions across app restarts
Both the Swift wallets dictionary and Kotlin's ShieldedTipSubmissions.wallets map exist only in process memory. Termination after a native broadcast but before a definitive result therefore recreates a ready guard on launch and loses the warning that the payment may already have executed. A user retry can build a second payment when other eligible notes are available. Durable native redrive records can restore the original transition and its note reservations, but those reservations protect the original inputs, not the user's payment intent; reserve_unspent_notes can still select different notes. Persist a network/wallet-scoped pending marker before invoking the native send, restore it as unresolved after restart, and resolve it only from a definitive outcome or shielded-activity reconciliation. Cover process recreation in both applications, separately from the existing sheet-reopening tests.

The new address rows reference owners only through scalar IDs, so deleting an identity or profile cannot cascade to them. The persistence handler calls removeOwned, but existing deletion paths bypass it: PersistentIdentity.remove and IdentitiesContentView.removeIdentityLocally delete the identity directly, while WalletKeyHealthSheet.deleteOrphan explicitly deletes the profile and then its identity. These paths leave the new payment-address rows behind. Besides retaining deleted owner/contact associations, the ID-based profile accessors can reconnect that stale metadata when the same identity and profile are recreated. Centralize cleanup and route every deletion entry point through it, or add an appropriate ownership relationship in the current schema while keeping frozen V4 unchanged. Add direct identity and orphan-deletion regressions.

- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:2405-2411: Release the wallet registry lock before resolving the recipient
HandleStorage::with_item retains its parking_lot read guard until the callback returns. This callback therefore holds the global PLATFORM_WALLET_STORAGE registry lock throughout block_on_worker, including the DPNS and profile network requests. A slow lookup blocks wallet-handle insertion and destruction for unrelated wallets; a queued writer can also delay subsequent readers. The cloned IdentityWallet already owns the state needed by the future. Obtain that clone inside with_item, release the registry guard, and execute the worker afterward while retaining the surrounding panic boundary.
In `packages/rs-platform-wallet-storage/tests/sqlite_profile_address_encoding.rs`:
- [SUGGESTION] packages/rs-platform-wallet-storage/tests/sqlite_profile_address_encoding.rs:102-108: Pin legacy migration compatibility with independently generated bytes
The migration fixture uses encode_legacy_identity and encode_legacy_profile, which serialize the same LegacyIdentityEntry and LegacyProfile declarations used by the production decoders. These tests exercise migration stamps and round trips, but do not independently pin compatibility with previously written bytes: a legacy field reorder could change fixture generation and decoding together while leaving the tests green. Add a checked-in fixture produced by the pre-V019 writer, or independently verified literal bytes, and exercise it through the migration, profile decoder, and both identity readers. Use distinct profile field values and nonempty collections following the embedded profiles so positional compatibility is covered. This is a regression-coverage gap, not evidence that the current legacy declarations decode incorrectly.
Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Complete C-side panic containment for existing wallet operations — Outside this PR's scope. The base revision already invokes block_on_worker without an inner panic guard in the older shielded-transfer export, and the submitted follow-up proposes a broader audit of existing exports. The new tip exports contain their worker calls; no additional PR-caused defect was established for the older operations.
- Follow-up: Consider creating a separate issue or author/maintainer-requested PR for this.

🟡 Suggestion: Release the wallet registry lock before resolving the recipient
HandleStorage::with_item retains its parking_lot read guard until the callback returns. This callback therefore holds the global PLATFORM_WALLET_STORAGE registry lock throughout block_on_worker, including the DPNS and profile network requests. A slow lookup blocks wallet-handle insertion and destruction for unrelated wallets; a queued writer can also delay subsequent readers. The cloned IdentityWallet already owns the state needed by the future. Obtain that clone inside with_item, release the registry guard, and execute the worker afterward while retaining the surrounding panic boundary.

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.
Split (2026-09-16): the contract field shipped separately in #4768 (merged into
v4.2-devfor 4.2.0) and the DPNS resolver fix in #4769 (4.2.0). This PR now carries only the wallet, persistence, native bindings, and Swift/Kotlin example flows, and targetsv4.3-dev(milestone v4.3.0). Nothing that remains here is consensus code.What was done?
profile.shieldedAddresson DashPay v2 at position 7, 43 raw bytes including the full diversifier; consensus enforces the byte length, clients validate the Orchard decoding) landed in feat(dpp)!: dashpay profile shielded address field #4768 together with the protocol 13 to 14 upgrade tests and the fee/root fixtures. This branch still carries byte-identical copies of those files; they become no-ops oncev4.3-devpicks up feat(dpp)!: dashpay profile shielded address field #4768.0x40000000 + 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
