feat(platform-wallet)!: top up an identity the wallet does not manage from Platform addresses - #5860
A wallet cannot pay credits from its Platform addresses to someone else's identity. IdentityWallet::top_up_from_addresses (and the PlatformWallet composite over it) reads the identity from the wallet's identity manager and returns IdentityNotFound for any identity the wallet does not manage. Dash Wallet iOS needs this for Platform → Identity ID sends in its new Send flow (dashpay/dashwallet-ios#1358); today that pair fails before anything is submitted.
What was done?
IdentityWallet::top_up_external_from_addresses — fetches the identity from Platform (Identity::fetch) and runs the same IdentityTopUpFromAddresses transition with the given inputs and address signer. It never adds the identity to the identity manager and persists nothing about it. An identity Platform does not know is IdentityNotFound, with nothing signed or broadcast.
PlatformWallet::top_up_external_identity_from_addresses — the composite: reconciles the spent Platform addresses through the same reconcile_address_infos path as the managed top-up.
The build / broadcast / error mapping now lives in one private helper used by both the managed and the external path.
FFI:platform_wallet_top_up_external_identity_from_addresses_with_signer, the same shape as the managed export; the input marshalling is shared between the two exports.
Swift:ManagedPlatformWallet.topUpExternalIdentityFromAddresses(identityId:inputs:addressSigner:) async throws -> UInt64 returns the identity's new balance and writes nothing to SwiftData. The managed and external wrappers share one marshalling helper.
docs/sdk/sdk-parity-manifest.json: new capability identity.external_top_up_from_addresses, Kotlin recorded as unsupported (PARITY_SUMMARY.md regenerated).
How Has This Been Tested?
cargo test -p platform-wallet -p platform-wallet-ffi — all pass. New Rust tests: an unmanaged identity's transition is built, signed once and broadcast once; the identity manager's identities are unchanged afterwards; an unknown identity returns IdentityNotFound with 0 signatures and 0 broadcasts. FFI tests: null pointers, zero inputs, a bad address type, not-found through a real handle.
Swift: ExternalIdentityTopUpTests 6/6 (marshalling, 32-byte id guard, error mapping). The full SwiftDashSDKTests target ran 942 tests with 2 failures in KeychainSignerAdditionalSigningKeysTests (the keychain write returns nil on the simulator); they fail the same way without this change.
Not covered: the success path end to end (top-up accepted, addresses reconciled). The mock SDK verifies the result proof for real and there are no recorded vectors for this transition, so the tests stop at "built, signed, broadcast once". It will be exercised by a testnet send from the wallet.
Breaking Changes
platform_wallet_top_up_from_addresses_with_signer and PlatformWallet::top_up_from_addresses no longer saturate when the funding rows naming one address sum past u64::MAX: the sum is refused with PlatformWalletError::InvalidParameter (FFI ErrorInvalidParameter, 2) before anything is signed or sent. Before, the FFI wrapper saturated the sum silently and topped up with u64::MAX credits for that address.
An empty list of funding rows still returns FFI ErrorInvalidParameter (2), but the check moved from the FFI wrapper ("inputs_count is zero", raised before anything else) into the library: the SDK's no-inputs refusal now surfaces as PlatformWalletError::InvalidParameter, where Rust callers of top_up_from_addresses got InvalidIdentityData before. For an identity the wallet does not hold, the managed path now reports IdentityNotFound (FFI 7) ahead of the empty-rows error, since the rows are no longer checked first.
New FFI code 80 ErrorIdentityLookupFailed (PlatformWalletError::IdentityLookupFailed, Swift PlatformWalletError.identityLookupFailed, Kotlin DashSdkError.PlatformWallet.IdentityLookupFailed): the new external top-up (platform_wallet_top_up_external_identity_from_addresses_with_signer) reports a failed recipient lookup as this code, with nothing signed or broadcast, so the call may be retried as it is. A missing identity stays ErrorIdentityNotFound (7). Hosts should treat 80 as "not sent", not as a possibly delivered top-up.
Both address top-ups (managed and external) now bind the confirmation to the address nonces they signed with: a proof whose input addresses are behind the submitted nonces (a state from before this top-up) is reported as StateTransitionResultUnconfirmed (FFI 20, do not submit again) with nothing reconciled, where it was reported as success. A failed wait or proof after the broadcast is also 20 now (it was 99), and a panic inside either export returns 20 instead of unwinding across the C boundary. Other SDK errors keep their typed Sdk variant instead of InvalidIdentityData.

Summary by CodeRabbit
New Features
Added support for topping up identities not managed by the wallet using address-based funding.
Address-based top-ups now accept repeated addresses and combine their amounts.
Bug Fixes
Identity lookup failures now return a specific, retryable error instead of a generic error.
Invalid or overflowing funding inputs are rejected, and failed lookups do not submit a top-up.
…from Platform addresses
top_up_from_addresses reads the identity from the wallet's identity manager and
returns IdentityNotFound for any other identity, so a wallet could not pay
credits from its Platform addresses to someone else's identity.
- IdentityWallet::top_up_external_from_addresses fetches the identity from
Platform and runs the same transition; it never adds the identity to the
manager or persists anything about it. An unknown identity is IdentityNotFound
with nothing signed or broadcast.
- PlatformWallet::top_up_external_identity_from_addresses reconciles the spent
addresses through the same path as the managed composite.
- FFI: platform_wallet_top_up_external_identity_from_addresses_with_signer,
sharing the input marshalling with the managed export.
- The build/broadcast/error mapping is shared by both paths.

Swift wrapper over platform_wallet_top_up_external_identity_from_addresses_with_signer:
tops up an identity the wallet does not manage from the wallet's Platform
addresses and returns the identity's new balance. It writes nothing to
SwiftData. The managed and external wrappers share one marshalling helper.
The parity manifest records the capability as unsupported in Kotlin.

Walkthrough
The wallet now supports address-funded top-ups for identities it does not manage. The FFI and Swift SDK expose the operation. Native error code 77 identifies Platform identity lookup failures, with typed error mappings and tests in Swift and Kotlin.

The FFI adds an external-identity top-up export and maps lookup failures to code 77. Tests cover input validation, missing identities, and registry access while signing is pending.
Swift adds the external top-up wrapper and a typed lookup error. Kotlin maps code 77 to IdentityLookupFailed. Tests and parity records document the support status.

Topping up an external identity from Platform addresses may report success when the recipient's balance has not yet changed, so a send could be recorded without crediting the identity. Funding shortfalls also cannot be identified programmatically, and the Kotlin lookup-failure error is not marked retryable. Resolve the success-confirmation concern before merging.

Final validation — Phase 1 + Phase 2
Verified the findings against b1b7129. The external top-up retains the existing proof-verification path, but the new spending route lacks wallet-generation protection, the shared FFI decoder owns funding-amount policy, and the reused Swift helper does not explicitly pin its signer across the FFI call. This was a static review: current Rust workspace, Swift SDK, and Kotlin SDK checks pass; dedicated Rust wallet tests were skipped, and review/hygiene checks remain pending.

🔴 Blocking: Pin the address signer across the synchronous FFI call packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/ManagedPlatformWallet.swift:896-907
The shared helper captures addressSigner only through the earlier _ = addressSigner, then invokes Rust using the separately captured raw handle. That discard is not a lifetime fence across the subsequent call in optimized Swift. KeychainSigner registers self with passUnretained, and its deinit destroys the Rust signer handle, so a short-lived signer can leave Rust with a freed handle or callback context while lookup, signing, or confirmation is still running. Other wrappers in this same file explicitly use withExtendedLifetime for this ownership arrangement and explain why a bare discard is insufficient. Wrap the complete synchronous call and its buffer-pinning closures in withExtendedLifetime(addressSigner). This is in scope: the PR moves this implementation into a shared helper and adds the external entry point as another caller, rather than merely sitting beside the existing pattern.
source: gpt-6.1-sol (phase2-reviewer: general, architecture-layering, ffi-engineer, rust-quality, security-auditor)
Triage: normal by gpt-6.1-sol (effort low) — The production changes add a straightforward external-recipient top-up path across Rust, FFI and Swift while reusing existing signing, submission and reconciliation logic, so the substantial test coverage does not make the implementation large or intricate enough for critical.
These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions don't block the merge, but most are worth fixing in this PR; judge each on its merits.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/platform_wallet.rs:622-628: Fence external top-ups against wallet removal and recreation
A retained wallet Arc or FFI handle can execute this spend after remove_wallet completes. Unlike the managed route's initial wallet-manager lookup, top_up_external_from_addresses only fetches the recipient and delegates to the SDK; neither it nor this composite checks the registered generation or participates in its lifecycle gate. Removal can also complete while recipient lookup or signing is suspended, after which the operation can still broadcast and reconcile through stale wallet state. The existing WalletGeneration contract explicitly requires network-publishing operations to exclude teardown, and the FFI removal hook does not invalidate PlatformWallet handles. Apply generation-aware protection in the Rust orchestration, covering submission and reconciliation and protecting the public identity-side route as well. Test retained handles, same-id recreation, and removal during signing; a wallet-id check before an await does not close the race.

- [BLOCKING] packages/rs-platform-wallet-ffi/src/identity_top_up.rs:150-161: Move funding-row normalization into the wallet library
This helper decides that repeated funding rows are additive and that overflowing amounts are silently saturated. Those are funding-amount decisions, not representation conversion: the wallet library receives only the resulting map and cannot own or consistently expose the normalization policy to native callers. The book's “FFI and mobile SDKs hold no business logic” rule explicitly places decisions about how many in the Rust library. This PR extracts that policy and extends it to the external export, so its pre-existence on the managed route does not exempt the new shared boundary. Introduce wallet-owned row normalization used by both routes, leaving the FFI to decode address representations and forward rows. Handle overflow explicitly in that owner and add duplicate-address and overflow tests there; neither branch is currently covered by the top-up FFI tests.

The present-identity fixture returns an empty, unverifiable result proof, so submitted top-ups always exit with StateTransitionResultUnconfirmed. This test discards that result and therefore establishes unchanged identity membership only on the unconfirmed path. Removing the new composite's reconciliation call, forwarding an incorrect proof height, or recording the recipient only after confirmation would leave the tests passing. Add a deterministic successful-result fixture or a narrow confirmed-submission test seam at the Rust composite boundary. Assert the returned identity balance, reconciled and persisted funding-address balances/nonces and height pin, and that the external recipient is neither added nor persisted as a managed identity. Existing reconciliation-seam tests do not cover this new route's wiring, and a future testnet send is not an automated regression test.

- [SUGGESTION] packages/swift-sdk/SwiftTests/SwiftDashSDKTests/ExternalIdentityTopUpTests.swift:90-101: Verify the external wrapper selects the external export
The parity manifest names this test as verification for identity.external_top_up_from_addresses, but it calls the shared topUpFromAddresses helper with a fake closure, bypassing the public external wrapper and its export selection. The code-7 test does the same. Tests that reach the public external method use malformed arguments or a null wallet handle, which cannot distinguish the managed and external exports. Consequently, changing the external wrapper to select the managed export would still pass this suite. Add a dispatch regression that distinguishes the two exports—for example, invoke the public wrapper with a mock-backed wallet and a recipient present on Platform but absent from its identity manager—and retain these shared-marshalling tests as separate coverage.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/top_up_from_addresses.rs:159-166: Preserve empty-input failures as invalid parameters
For an existing recipient, an empty Rust input map is rejected by the SDK's fetch_inputs_with_nonce with a typed TransitionNoInputsError, but this fallback converts it into InvalidIdentityData. The FFI rejects the same caller mistake as ErrorInvalidParameter, and PlatformWalletError::InvalidParameter explicitly documents that distinction. Native callers therefore receive an identity-data failure for a malformed funding argument and lose the typed repair signal. Preserve the SDK's empty-input discriminator as InvalidParameter in this error mapping and add coverage for both top-up routes. Reuse the SDK's validation rather than adding another copy of the empty-input rule.
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.
External top-up leaves a managed identity's cached balance stale if called with an owned id — The API is explicitly documented at both Rust entry points as topping up an identity this wallet does not manage, and it deliberately neither reads nor writes the identity manager. Managed recipients already have a separate operation that updates their cached balance. The proposed documentation alternative is already present; using the external API outside that documented recipient contract does not establish a defect.
Follow-up: Consider creating a separate issue or author/maintainer-requested PR for this.

…funding-row policy
Review fixes for the external identity top-up:
- The external composite takes the wallet generation's payment guard and
checks the generation is current before fetching the identity, holding it
through signing, broadcast and reconcile; a removed or recreated wallet gets
WalletRemovedBeforeSend with nothing signed or sent.
- platform-wallet now takes the funding rows, sums repeated addresses and
refuses an overflowing sum with InvalidParameter; the FFI only converts row
types, for both the managed and the external export. The managed export now
errors on overflow instead of saturating, and its empty-input check moves to
the library.
- The SDK's TransitionNoInputsError maps to InvalidParameter on both routes.
- Swift: the shared helper pins addressSigner with withExtendedLifetime across
the synchronous FFI call; the exports are injectable and a test through both
public wrappers shows each calls its own export.
- A composite seam test covers a confirmed external top-up: balance returned,
spent address reconciled and persisted at the proof height, identity manager
unchanged.

🔴 Blocking: Release the wallet registry before waiting on the host signer packages/rs-platform-wallet-ffi/src/identity_top_up.rs:185-194
HandleStorage::with_item holds its process-global parking_lot registry read guard throughout this closure, including block_on_worker. Cloning the wallet inside the closure therefore does not release the registry during recipient lookup, foreign signer callbacks, broadcast or proof waiting. ManagedPlatformWallet.deinit synchronously calls platform_wallet_destroy, which needs this registry's write lock, so releasing even an unrelated wallet wrapper on the UI thread blocks it for the network/signing wait.
A queued destroy also prevents subsequent registry readers from proceeding. If host signing completion work reads a wallet balance, it waits behind that writer while the export waits for signing, producing a lock cycle; an asynchronously returning signer only escapes through its timeout. Clone the wallet Arc in a short with_item call, unwrap it, and invoke block_on_worker after that call has returned, as the existing DashPay exports do. Add a regression that holds signing while destroying another wrapper and reading a balance.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/network/top_up_from_addresses.rs:151-158: Fence external top-ups against wallet removal and recreation
The new composite guard protects PlatformWallet and FFI callers, but the separately public IdentityWallet entry point still bypasses it. A native caller can retain wallet.identity().clone(), await manager.remove_wallet(...), then invoke this method: it fetches the recipient and reaches SDK signing and broadcast without checking self.generation or taking its lifecycle gate. Removal can also complete while a direct call is suspended in signing, allowing the spend afterward. Same-ID recreation does not invalidate the retained SDK or external signer.
This is the new external API, not the pre-existing managed-route gap you left unchanged. The non-reentrant gate prevents simply nesting another acquisition, but does not require leaving a public spending route unprotected. Provide a guarded public identity-side method backed by a separate internal already-guarded implementation, so the composite retains one guard through reconciliation; alternatively, make the unfenced method internal and expose only the guarded composite. Add direct identity-handle regressions for removal, recreation and suspended signing; the current lifecycle tests invoke only the composite.

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.
Fence the existing managed address-funded top-up separately — The managed top-up releases its wallet-manager lookup before submission and later updates identity state by wallet ID without lifecycle exclusion or generation comparison. Removal can interleave with submission, and same-ID recreation can receive a stale handle's confirmed balance update. This lifecycle defect exists in the review base and is separate from the newly added external API.
Follow-up: Create a follow-up issue or PR adding generation-aware lifecycle protection to the managed identity-side and composite routes, covering submission, identity persistence and address reconciliation.
…on the signer
Both address top-up exports ran block_on_worker inside
PLATFORM_WALLET_STORAGE.with_item, so the registry read guard stayed held
while the host signed. A wallet handle destroy (write lock) queued behind it,
and any registry read queued behind that destroy, so a signing completion that
reads a balance could never finish.
Clone the wallet Arc in a short with_item and wait on the signer after it
returns. The regression test holds a callback signer pending, then destroys a
second wallet handle and reads a balance; both must finish before the signer
is answered, for both exports.

Registry-lock finding from the re-review (identity_top_up.rs:185): fixed in 77c2161.

🟡 Suggestion: Bound the lifecycle test's signer rendezvous packages/rs-platform-wallet/src/wallet/identity/network/top_up_from_addresses/external_identity_tests.rs:470
If recipient lookup or transition preparation returns an error or panics before HeldSigner::sign, the spawned task finishes without notifying this wait. Notify does not report producer termination, and the test does not inspect the top-up JoinHandle until after receiving the notification, so the regression hangs instead of reporting the preparation failure. Add a deadline to this rendezvous, or select between the notification, task completion, and a deadline.

🟡 Suggestion: Keep empty-funding validation in Rust packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/ManagedPlatformWallet.swift:852-854
The extracted helper extends this Swift-side input-count rule to the new external top-up API. DPP's IdentityTopUpFromAddressesTransitionV0::validate_structure already owns the rule, the SDK's fetch_inputs_with_nonce rejects empty inputs before signing, and the shared wallet submission helper maps that typed refusal to InvalidParameter. Unlike byte-width checks needed to construct fixed-size C values, rejecting an empty collection is semantic validation. This violates the book's explicit prohibition on duplicating DPP count checks in bindings and bypasses Rust's error ordering: an empty call through a removed wallet returns WalletRemovedBeforeSend natively but invalidParameter here. Remove this guard and forward empty funding collections to Rust. Update both FFI exports to accept a null input pointer when the count is zero, and construct an empty collection without calling slice::from_raw_parts on null. Replace the Swift test requiring pre-FFI rejection with coverage that the public wrapper forwards the Rust-emitted refusal.

Triage: critical by gpt-6.1-sol (effort low) — This is a large, intricate change to funds movement, transaction construction, address reconciliation, signing, broadcasting, and FFI/Swift key-handling paths in IdentityWallet::top_up_external_from_addresses and its platform-wallet/FFI wrappers.

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.
Fence the pre-existing managed top-up route against wallet teardown — IdentityWallet::top_up_from_addresses releases its initial wallet-manager read before signing and submission without holding the generation lifecycle gate. A signature suspended during removal can resume and broadcast after removal completes, and subsequent local reconciliation can report WalletNotFound despite the spend. This race is present in the merge-base; the new external composite protects its own route.
Follow-up: Create a separate follow-up PR protecting both public managed address-top-up entry points against removal and same-ID recreation, with a regression that suspends signing during removal.

Approving. Two notes, non-blocking:
The managed top_up_from_addresses path changes on edge cases: an overflowing sum of funding rows now returns InvalidParameter instead of saturating, and the empty-inputs error code changed. Worth a line under Breaking Changes in the PR body.
On the external path, a failed Identity::fetch surfaces as a generic Sdk error even though nothing was signed or broadcast yet; a dedicated not-sent classification would help hosts that treat unknown errors as "may have gone through".
…l top-up as not sent
A failed `Identity::fetch` on the external identity top-up surfaced as a
generic `Sdk` error although nothing had been signed or broadcast, which
a host treating unknown errors as "may have gone through" cannot tell
from a failure after a dispatch. It is now
`PlatformWalletError::IdentityLookupFailed`, mapped to the new FFI code
77 `ErrorIdentityLookupFailed` and mirrored in Swift and Kotlin. A missing
identity keeps `IdentityNotFound` (7). No existing code meant "refused
before anything was sent" for a Platform state transition.

Do not return an affected-state top-up snapshot as a completed payment.
The route waits with wait_for_affected_state_with_metadata. The verifier treats a top-up result as height-pinned state, not execution evidence. top_up_result checks the identity ID, the address set, and balance presence. It does not compare the submitted address nonces or the balance before and after the top-up. The route can therefore return Ok with the recipient's unchanged balance when the snapshot predates execution. Callers that treat Ok as completed payment can record a send that did not credit the identity.
Before returning success, check that each spent address advanced its nonce past the submitted value, or that the identity balance increased. If neither holds, return a distinct pending or not-confirmed result instead of success. The exact check depends on the AddressInfos nonce and balance fields, which were not inspected, so no code edit is proposed here.

@romchornyi The new checks reject an unchanged snapshot. My earlier suggested checks were not sufficient to prove that this top-up executed.
If a competing spend consumes the same nonces and an unrelated payment increases the identity balance, bind_to_submitted_nonces can still return success. The affected-state proof does not bind those changes to this transition.
Please use execution-bound evidence if available, or report the result as unconfirmed when execution cannot be established. A regression test should cover the competing-spend and unrelated-credit case. I am not marking the finding as addressed yet.

Re-review — Final validation — Phase 2 only (queue backlog)
The external top-up path still treats an affected-state proof as confirmation that the submitted transition completed, so it can report success and reconcile a payment without execution evidence. The new and refactored C exports also allow worker panics to reach the extern C boundary, while the shared Rust fallback and Kotlin error mirror lose retryable/typed error semantics. Rust and Kotlin CI checks passed; the Swift build remains queued.
Triage: critical by gpt-6.1-sol (effort low) — This is a large, intricate change to platform-wallet identity top-up flows that directly builds, signs, broadcasts, and reconciles credit-funding transitions, including new external-identity handling and signer/FFI/Swift boundaries in packages/rs-platform-wallet/src/wallet/identity/network/top_up_from_addresses.rs and platform_wallet.rs.
Phase 1 reviewers: not run (skipped for throughput: 17 PRs queued, above the 10 limit)

These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions don't block the merge, but most are worth fixing in this PR; judge each on its merits.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/network/top_up_from_addresses.rs:180-192: Do not report an affected-state snapshot as a completed external top-up
`submit_top_up_from_addresses` waits with `wait_for_affected_state_with_metadata`, whose contract explicitly permits a height-pinned snapshot of the identity and addresses without proving that this submitted transition executed. The Drive verifier classifies `IdentityTopUpFromAddresses` as non-execution-binding because it checks only current identity balance/revision and address state, not the requested amounts, submitted nonces, or transition identity. `top_up_result` then validates only the identity id, expected address set, and presence of a balance, after which the composite returns success and reconciles the addresses. A valid snapshot from before or independent of this top-up can therefore cause callers to record a completed payment and retry later, potentially sending twice. This API needs an execution-proved confirmation from the SDK/proof owner, or must return a distinct pending/unconfirmed result rather than treating the affected-state snapshot as payment completion.
- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/top_up_from_addresses.rs:184-192: Preserve unpromoted SDK errors at the wallet boundary
After the address-nonce and empty-input promotions, the fallback converts every other SDK error into `InvalidIdentityData(String)`. This discards the original SDK variant and its `consensus_error()` metadata; for example, a typed address-funds rejection reaches the FFI conversion as `InvalidIdentityData` and falls through to a generic error instead of retaining its actionable source. The existing `PlatformWalletError::Sdk` variant is the preserving shape used by the FFI mapping. Keep the two explicit promotions, then carry all other SDK failures unchanged.

- [BLOCKING] packages/rs-platform-wallet-ffi/src/identity_top_up.rs:164-197: Prevent worker panics from escaping the address top-up C exports
Both address top-up exports call `block_on_worker` directly. That helper calls `rt.spawn(future).await.expect("tokio worker panicked")`, so a panic in identity lookup, proof processing, signing, or reconciliation is re-panicked inside an `extern "C"` function and can terminate the host instead of returning a `PlatformWalletFFIResult`. The FFI crate already provides `catch_panic_to_code`; wrap the complete managed and external export bodies with an ambiguity-safe result code and guidance, because a panic may occur after signing or broadcast and must not be reported as a definitive unsent failure.
_Raised on code unchanged since the last review, and confirmed by an independent pass: A valid call to the new external export can encounter a panic in the spawned top-up future after signing or broadcast; `block_on_worker` turns that task panic into a panic via `expect`, which reaches the `extern "C"` boundary and aborts the host instead of returning a `PlatformWalletFFIResult`._

Fixed in 091026e. There is no execution proof for IdentityTopUpFromAddresses (the verifier classifies it as non-execution-binding), so both address top-ups now look up the input nonces themselves, submit with them (top_up_from_addresses_with_nonce_with_metadata) and bind the affected-state result to them: if any input address in the proof is behind its submitted nonce or missing, the result is StateTransitionResultUnconfirmed(ExecutionNotProved) (FFI 20, do not submit again) and nothing is reconciled. A proof showing every submitted nonce used means this transition either executed or can no longer execute, so it cannot be sent twice; the remaining gap (another transition this wallet signed with the same nonce) can only under-report, never double-pay.
The reason will be displayed to describe this comment to others. Learn more.
Still applies (re-reviewed at 46428085): The nonce binding fixes snapshots from before the submitted nonce, but a competing operation can consume the same nonce and leave the intended recipient unchanged. Returning that affected-state snapshot as Ok still lets callers record a payment that this top-up did not make.

Fixed in 69ffa84. Used nonces are no longer enough: the result also needs the proved identity balance above the balance the top-up started from, otherwise it is StateTransitionResultUnconfirmed(ExecutionNotProved) (FFI 20) and nothing is reconciled. A same-nonce transition that paid elsewhere therefore reads as unconfirmed, not done (test should_report_used_nonces_without_a_higher_identity_balance_as_unconfirmed).

Fixed in 3cfd952. Both address top-up exports run inside catch_panic_to_code and report a panic as ErrorTransactionBroadcastUnconfirmed (20, do not submit again), since it may follow signing or broadcast; the balance output is left untouched. Note the iOS profiles build with panic=abort, so the guard applies to the other targets.

Still applies (re-reviewed at 46428085): The new catcher handles unwinding targets, but the iOS dev-ios and release-ios profiles still use panic = "abort"; an iOS worker panic therefore terminates the host instead of returning code 20.

Not changing this here: panic = "abort" in dev-ios/release-ios is a workspace-wide profile that applies to every FFI export, not only these two, so switching iOS to unwinding is a separate decision with its own size and behaviour trade-offs. On the targets that unwind, both exports now return code 20 instead of aborting.

…r of the shielded spend plan codes
The failed identity lookup code was 77, which the shielded spend plan PR
already uses (77 plan changed, 78 too many notes, 79 withdrawal amount out
of range). Renumber it to 80 in the FFI enum, the registry (next free is
now 81), the Swift result code and the Kotlin error mapping, and update the

… unbound state snapshot
The result proof of an identity top-up from addresses authenticates only
the identity and address state at the proof's block, not that this
transition executed. The wallet now signs with nonces it looked up itself
and keeps the result only when the proof shows every input address at or
past its submitted nonce. A snapshot from before is reported as the SDK's
unconfirmed outcome, with nothing reconciled from it, on both the managed
and the external top-up.

…into a result code
Both address top-up exports ran the composite through block_on_worker,
which re-panics a worker panic inside the extern "C" function and ends
the host. Their bodies now run under catch_panic_to_code and report
ErrorTransactionBroadcastUnconfirmed (20): the panic may strike after
signing or broadcast, so the top-up may still execute and must not be
submitted again.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The address top-up promotes a nonce race and an empty input map to their
own errors; every other SDK error was flattened into an
InvalidIdentityData string, losing its typed variant and consensus cause.
It is now kept as PlatformWalletError::Sdk.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
IdentityLookupFailed (code 80) means nothing was signed, reserved or

so, as the code-80 mapping test asserts.

Re-review — Final validation — Phase 1 + Phase 2
Four in-scope blocking correctness defects remain: nonce advancement can be caused by a competing transition, the iOS panic-abort profiles defeat the new panic catcher, detached Swift top-ups do not retain the wallet owning the FFI handle, and the managed address-top-up route remains unfenced against wallet removal. The Rust workspace and Swift SDK code checks reported success, with no failed code checks attributed to this change.
A pattern across this PR's review rounds
This is review round 5, and the PR has drawn 8 blocking findings so far. 4 of them share one underlying cause. They are listed with the other findings as usual; fixing the cause is likely to be cheaper than fixing each case.
1. No operation-scoped lifetime owner (1 new in this round, 3 earlier finding(s))
The address top-up has no single owner for the resources it uses across the Swift and Rust boundaries. The detached Swift call copies raw wallet and signer handles, while Rust lifecycle protection is attached to selected entry points, so each review fix adds a fence at one path and leaves another owner or entry point able to outlive the operation. This is why retaining the signer still left the wallet handle vulnerable during the same network-publishing call.
In this round: Keep ManagedPlatformWallet alive for the detached top-up call
Suggested decision (redesign the component): Redesign the address-top-up boundary around one operation-scoped lease instead of adding more per-call lifetime guards. The lease must retain the Swift wallet and signer owners and hold one Rust wallet generation through lookup, signing, broadcast, confirmation, and reconciliation, with both managed and external APIs using that same path. Do not extend this feature with further entry points until that ownership model is in place.
If a later review again finds new blockers from this cause, it will ask for that decision and pause automatic re-review until it is made.

Triage: critical by gpt-6.1-sol (effort low) — This is a large, cross-language change that modifies identity top-up funds movement and transaction signing in IdentityWallet, PlatformWallet, FFI, and Swift wrappers, including new external-identity handling and changed validation behavior.
Phase 1 model: muse-spark-1.3-contributor — not quota-gated; passed over gemini-3.8-flash-high (antigravity quota lookup failed), glm-5.3-flash (not used above high effort; tier asks max)
Single stage: Phase 1 and Phase 2 reviewed this head side by side, with no blocker gate between them (triage tier)
Code unchanged since the last final review (ccf95e59): 1 new blocker(s) went to an independent confirmation pass (the final verifier's model in a fresh session, without its reasoning): 1 confirmed
Several findings on this PR share an underlying cause (the review's "pattern" section): No operation-scoped lifetime owner. When you fix the findings below, fix the cause, not only the reported case. The review suggests (redesign the component): Redesign the address-top-up boundary around one operation-scoped lease instead of adding more per-call lifetime guards. The lease must retain the Swift wallet and signer owners and hold one Rust wallet generation through lookup, signing, broadcast, confirmation, and reconciliation, with both managed and external APIs using that same path. Do not extend this feature with further entry points until that ownership model is in place. If that decision is not yours to make, say so to the PR's author or maintainer.
These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions don't block the merge, but most are worth fixing in this PR; judge each on its merits.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.

- [BLOCKING] packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/ManagedPlatformWallet.swift:872-873: Keep ManagedPlatformWallet alive for the detached top-up call
The detached closure captures `handle` and `addressSignerHandle`, but not the `ManagedPlatformWallet` instance that owns `handle` in the FFI registry. Swift may release the last wallet reference after the local handle is copied and before the detached task invokes the export; `deinit` then destroys the registry handle while the task is still pending. The export can fail before Rust obtains its protective wallet clone, and a future handle reuse could make the call target a different wallet. Capture the wallet owner or otherwise use `withExtendedLifetime(self)` across the synchronous FFI invocation, and add a regression that releases the wallet while the export is blocked.
_Raised on code unchanged since the last review, and confirmed by an independent pass: After `self.handle` is copied, the detached closure captures only the raw handle and not `self`; the wallet can therefore deinitialize while the task is pending, destroying the FFI registry handle before the export resolves it. The call then fails or, if the handle is reused, can dispatch against a different wallet._

Fixed in 9470844. The detached call now pins the wallet together with the signer (withExtendedLifetime((self, addressSigner))) for the whole synchronous export call, as refreshIdentityBalance does. (The caller already holds self until .value returns, so this makes the guarantee explicit rather than closing a reachable path.)
… did not grow as unconfirmed
Used input nonces show that a transition this wallet signed with them executed, not that it paid the
identity: another transition with the same nonces could have spent them elsewhere. The result now also
needs the proved identity balance above the one the top-up started from; otherwise it is
StateTransitionResultUnconfirmed(ExecutionNotProved) (FFI 20) and nothing is reconciled.

The detached call copies the wallet handle that ManagedPlatformWallet's deinit destroys; pin the wallet
together with the signer for the whole synchronous FFI call, as refreshIdentityBalance does.

… removal
PlatformWallet::top_up_from_addresses now runs through the same seam as the external top-up
(top_up_identity_with): it holds the generation's lifecycle gate from the liveness check through signing,
broadcast and reconciliation, and a wallet removed or re-created since the handle was taken is refused
with WalletRemovedBeforeSend, nothing signed or sent.

Issue being fixed or feature implemented
A wallet cannot pay credits from its Platform addresses to someone else's identity.
IdentityWallet::top_up_from_addresses(and thePlatformWalletcomposite over it) reads the identity from the wallet's identity manager and returnsIdentityNotFoundfor any identity the wallet does not manage. Dash Wallet iOS needs this for Platform → Identity ID sends in its new Send flow (dashpay/dashwallet-ios#1358); today that pair fails before anything is submitted.What was done?
IdentityWallet::top_up_external_from_addresses— fetches the identity from Platform (Identity::fetch) and runs the same IdentityTopUpFromAddresses transition with the given inputs and address signer. It never adds the identity to the identity manager and persists nothing about it. An identity Platform does not know isIdentityNotFound, with nothing signed or broadcast.PlatformWallet::top_up_external_identity_from_addresses— the composite: reconciles the spent Platform addresses through the samereconcile_address_infospath as the managed top-up.platform_wallet_top_up_external_identity_from_addresses_with_signer, the same shape as the managed export; the input marshalling is shared between the two exports.ManagedPlatformWallet.topUpExternalIdentityFromAddresses(identityId:inputs:addressSigner:) async throws -> UInt64returns the identity's new balance and writes nothing to SwiftData. The managed and external wrappers share one marshalling helper.docs/sdk/sdk-parity-manifest.json: new capabilityidentity.external_top_up_from_addresses, Kotlin recorded as unsupported (PARITY_SUMMARY.mdregenerated).How Has This Been Tested?
cargo test -p platform-wallet -p platform-wallet-ffi— all pass. New Rust tests: an unmanaged identity's transition is built, signed once and broadcast once; the identity manager's identities are unchanged afterwards; an unknown identity returnsIdentityNotFoundwith 0 signatures and 0 broadcasts. FFI tests: null pointers, zero inputs, a bad address type, not-found through a real handle.cargo clippy -p platform-wallet -p platform-wallet-ffi -- -D warnings,cargo fmt --all -- --check— clean.ExternalIdentityTopUpTests6/6 (marshalling, 32-byte id guard, error mapping). The fullSwiftDashSDKTeststarget ran 942 tests with 2 failures inKeychainSignerAdditionalSigningKeysTests(the keychain write returns nil on the simulator); they fail the same way without this change.Breaking Changes
platform_wallet_top_up_from_addresses_with_signerandPlatformWallet::top_up_from_addressesno longer saturate when the funding rows naming one address sum pastu64::MAX: the sum is refused withPlatformWalletError::InvalidParameter(FFIErrorInvalidParameter, 2) before anything is signed or sent. Before, the FFI wrapper saturated the sum silently and topped up withu64::MAXcredits for that address.An empty list of funding rows still returns FFI
ErrorInvalidParameter(2), but the check moved from the FFI wrapper ("inputs_countis zero", raised before anything else) into the library: the SDK's no-inputs refusal now surfaces asPlatformWalletError::InvalidParameter, where Rust callers oftop_up_from_addressesgotInvalidIdentityDatabefore. For an identity the wallet does not hold, the managed path now reportsIdentityNotFound(FFI 7) ahead of the empty-rows error, since the rows are no longer checked first.New FFI code 80
ErrorIdentityLookupFailed(PlatformWalletError::IdentityLookupFailed, SwiftPlatformWalletError.identityLookupFailed, KotlinDashSdkError.PlatformWallet.IdentityLookupFailed): the new external top-up (platform_wallet_top_up_external_identity_from_addresses_with_signer) reports a failed recipient lookup as this code, with nothing signed or broadcast, so the call may be retried as it is. A missing identity staysErrorIdentityNotFound(7). Hosts should treat 80 as "not sent", not as a possibly delivered top-up.Both address top-ups (managed and external) now bind the confirmation to the address nonces they signed with: a proof whose input addresses are behind the submitted nonces (a state from before this top-up) is reported as
StateTransitionResultUnconfirmed(FFI 20, do not submit again) with nothing reconciled, where it was reported as success. A failed wait or proof after the broadcast is also 20 now (it was 99), and a panic inside either export returns 20 instead of unwinding across the C boundary. Other SDK errors keep their typedSdkvariant instead ofInvalidIdentityData.Checklist:
