fix(platform-wallet): harden asset-lock recovery — invisible chain-locked rows, two unbounded waits by bfoss765 · Pull Request #4422 · dashpay/platform

Summary

Three audit findings on the merged asset-lock recovery surface, from a review of #4347, #4357 and #4367 at the v4.2-dev tip (c99872b08b). Each is a regression introduced by one of those PRs; each is fixed here with tests.

#	Origin	Severity	Symptom
F1	#4347	High	A chain-locked top-up is invisible on every host surface — funds read as lost
F2	#4357	High	Already-consumed reconciliation can pin the calling host thread forever
F3	#4367	Medium-High	A ~30s broadcast failure becomes an indefinite wait; cleanup is lost

F1 — recovered asset locks are invisible (#4347)

Chain-locked enrichment promotes tracked locks to AssetLockStatus::RecoveredFromChain (discriminant 5) in sync/reconstruction.rs, but every host resume surface expressed "still recoverable" as the contiguous range 1..3. Status 5 sits above the terminal Consumed (4) numerically while being decidedly non-terminal, so those filters dropped exactly the rows the restore scan had just rebuilt.

User scenario. A user funds a Platform address top-up. It confirms and gets chain-locked. They restore the wallet from seed. The restore scan rebuilds the lock, attaches a real ChainAssetLockProof, and writes status 5 — and then the top-up appears nowhere: not in Pending Platform Top Ups, not in Resumable Registrations. The Swift UI labelled it Unknown(5). Rust would resume it happily; nothing in the UI can reach it, so the funds read as lost.

AssetLockDao.observeResumableAddressTopUps now admits 1..3 ∪ {5}. 4 stays excluded — it is the tombstone resume_asset_lock rejects, and re-surfacing it recreates the perpetual-spinner row the fix(platform-wallet): finalize reconstructed asset locks as RecoveredFromChain, in-session #4347 guard prevents.
New AssetLockDao.observeResumableTopUpsByFundingType. Shielded address top-ups (funding type 5) had no resumable query at all: the address query is pinned to funding type 4, and the identity-recovery surface admits only funding types 0..2. A stalled shielded top-up was invisible everywhere.
Swift isVisibleAsResumable / canFundIdentity accept 5 and statusLabel names it; crossWalletResumableLocks now reuses the shared predicate rather than restating the range.

One deviation from the filed finding. The finding proposed also mapping funding types 4/5 into TrackedAssetLock.FundingType. I did not do that, because that enum is the identity-recovery eligibility filter and its consumers assert on it — IdentityRegistration.registerIdentity requires IDENTITY_REGISTRATION, IdentityCredits requires the two top-up variants. Admitting address/shielded locks would route them into pickers whose require(...) then throws: a new crash path, not a fix. The correct surface for those funding types is the DAO query above. Its status 5 mapping was already present and is unchanged.

F2 — unbounded ChainLock wait in reconciliation (#4357)

reconcile_asset_lock_submit_result upgrades an Instant proof via upgrade_to_chain_lock_proof(out_point, chain_lock_timeout), and all three production call sites pass None (identity/network/registration.rs:272, :512, platform_addresses/fund_from_asset_lock.rs:272). The None arm of wait_for_chain_lock is an unbounded loop.

User scenario. A lock is IS-locked and consumed seconds after broadcast, so Platform answers with the unauthenticated "already consumed" report while the ChainLock is still ~2.5 minutes away — or never arrives, because the device is offline or SPV is not connected. Every call site reaches this under an FFI runtime().block_on(...), so the host thread that made the call is pinned, not merely delayed. Pre-#4357 this returned a typed error immediately.

None now selects RECONCILIATION_CHAIN_LOCK_TIMEOUT (180s). Because the ChainLock is wanted only as evidence to record alongside a report about an operation that has already terminated, failure to obtain it degrades rather than propagates: the lock keeps its status and the typed AssetLockAlreadyConsumed is still returned, so the code-24 signal is preserved and the caller can retry. #4357's proof retention is untouched whenever the ChainLock is reachable inside the bound.

F3 — `MaybeSent` treated as "accepted" (#4367)

A MaybeSent broadcast outcome on a Built lock advances it to Broadcast. But MaybeSent is the normal verdict for a genuinely rejected transaction: DapiBroadcaster classifies every failure as MaybeSent by construction (broadcaster.rs:103-119), and the SPV broadcaster reaches Rejected only on NotConnected (spv/runtime.rs:126-130; no BIP61 in modern Dash).

User scenario. A resume re-broadcasts a transaction the network rejects. The verdict is MaybeSent, the lock advances to Broadcast, and wait_for_proof(None) waits for a proof that can never arrive — a failure that used to surface in ~30 seconds now never returns.

(a) The advance is kept — it is what stops each recovery pass repeating the same broadcast — but when the caller asked for an unbounded wait, the proof wait is bounded by UNCONFIRMED_BROADCAST_PROOF_TIMEOUT and its expiry is translated back into the pre-#4367 TransactionBroadcastUnconfirmed. Callers that supplied their own timeout are untouched, FinalityTimeout and all: the shielded seed pool treats that error as a pacing signal, so re-typing it for everyone would break a working flow to fix a different one.

(b) The Broadcast arm no longer swallows a definite Rejected. It logged every broadcast error and fell through to wait_for_proof — right for the ambiguous verdict, but a guaranteed dead wait for a verdict meaning that attempt provably did not happen. It now surfaces the error, after a zero-bound probe of the local record so a proof that landed in between is still picked up. The row is deliberately kept tracked: a re-broadcast Rejected (with the production SpvBroadcaster: an unstarted client or zero connected peers) describes only that attempt, never the original broadcast that moved the row to Broadcast in an earlier process, so it is not evidence the transaction is absent from the network. The next recovery pass resumes the row.

A second deviation, for fund safety. The finding asked to widen untrack_asset_lock (or add an unproven-row untrack companion). This PR deliberately adds no untrack path at all — a NOTE in tracking.rs documents why: removing rows on a re-broadcast Rejected deleted tracking for possibly-mined asset locks during ordinary offline periods, and "the row was removed" is build.rs:954's trigger to release the funding-input reservation, so any rejection-driven removal is a double-spend opening for inputs whose transaction may be live. Rows stay tracked; inputs stay reserved until the TTL backstop.

Release note — FFI contract change

resume_asset_lock / asset_lock_manager_catch_up with timeout_secs == 0 no longer means "wait indefinitely": zero now selects the recovery policy's state-dependent default (180s bounds for proof/ChainLock waits). A non-zero timeout_secs keeps its exact semantics. Hosts that relied on 0 as unbounded get bounded waits and a typed TransactionBroadcastUnconfirmed on expiry instead of a hang; both FFI entry-point docs were rewritten to state this.

Test evidence

cargo test -p platform-wallet --features shielded — 851 passed, 0 failed, 3 pre-existing ignored.
cargo test -p platform-wallet-ffi --features shielded — 318 passed, 0 failed.
:sdk:testDebugUnitTest --tests AssetLockResumableDaoTest — 7 passed, 0 failed (Robolectric, in-memory Room).
cargo clippy -p platform-wallet --features shielded --tests -- -D warnings — clean. cargo fmt --check — clean. Default-feature build also checked.

12 tests added:

F1 (7 Kotlin + 1 Swift): status 5 in, 4 out, 0 out; whole recoverable domain; funding-type and wallet scoping intact; shielded funding type covered; parameterized query agrees with the address query.
F2 (1): already_consumed_reconciliation_terminates_without_a_chainlock — Instant proof, record present but not chain-locked, no chainlock ever delivered, chain_lock_timeout: None. Asserts it resolves at all, resolves as AssetLockAlreadyConsumed, and does not promote the lock without a proof.
F3 (4): unbounded ambiguous resume terminates as TransactionBroadcastUnconfirmed with the row still at Broadcast; bounded callers still get FinalityTimeout; definite rejection on a Broadcast lock surfaces the error with the row left tracked and resumable.

The two hang regressions were verified to reproduce: with the F3 fixes reverted, the test binary hung indefinitely with no output rather than failing, which is the defect itself. The start_paused runtimes let the bounded versions complete instantly.

Residual limitations

Swift is compile-reviewed, not executed. SwiftExampleApp needs a built DashSDKFFI.xcframework, which is not present in this worktree, so xcodebuild cannot resolve the package graph. The Swift edits are small and local (two predicates, one label case, one added test).
F2 loses proof retention on timeout. When no ChainLock is reachable inside 180s, the lock is not recorded as consumption-unknown. This is deliberate — mark_asset_lock_consumption_unknown rejects a non-Chain proof by design — and matches pre-fix(platform-wallet): preserve reported-consumed asset-lock recovery #4357 behavior. A later retry can still attach the proof.
mark_asset_lock_consumption_unknown errors still propagate in F2's has-proof path (e.g. missing persistence capabilities), which can still mask the code-24 signal. Left as-is: that is pre-existing behavior on a path where a persistence failure should be loud, and changing it is outside this scope.
The 180s constants are policy, not derived. Sized to comfortably cover a ChainLock (~2.5 min) and consistent with the existing CL_FALLBACK_TIMEOUT. Happy to thread explicit per-call-site timeouts instead if reviewers prefer.
A rejected re-broadcast keeps its inputs reserved (the row is kept, nothing is untracked) until the TTL backstop — deliberate, because the original transaction may already be mined.

Summary by CodeRabbit

New Features
- Recovered asset locks now appear as resumable and fundable.
- Resumable top-ups include address and shielded funding across wallets.
- Resume flows route to the appropriate address or shielded funding experience.
- Recovered lock statuses are displayed clearly in the example apps.
Bug Fixes
- Asset-lock recovery now uses bounded waits for delayed confirmations.
- Unconfirmed broadcasts are classified more accurately while valid tracked locks are preserved.
- Funding actions prevent conflicting operations and allow safe retries.
- Missing or unsupported resume destinations now fail safely.

Chain-locked enrichment promotes tracked asset locks to `AssetLockStatus::RecoveredFromChain` (discriminant 5) in `sync/reconstruction.rs`, but every host resume surface expressed "still recoverable" as the contiguous range `1..3`. Status 5 sits above the terminal `Consumed` (4) numerically while being decidedly non-terminal, so each of those filters silently dropped exactly the rows the restore scan had just rebuilt. User-visible effect: an address top-up that was funded and chain-locked before a wallet restore appears on no surface at all — not the Pending Platform Top Ups list, not the Resumable Registrations list — and the Swift status label rendered it as "Unknown(5)". The funds are intact and Rust will happily resume them, but nothing in the UI can reach them, so they read as lost. Changes: - `AssetLockDao.observeResumableAddressTopUps` admits `1..3 ∪ {5}`. `4` stays excluded: it is the terminal tombstone that `resume_asset_lock` rejects, and re-surfacing it would produce the perpetual-spinner row the #4347 guard exists to prevent. - New `AssetLockDao.observeResumableTopUpsByFundingType`. Shielded address top-ups (funding type 5) previously had no resumable query at all — the address query is pinned to funding type 4, and the identity-recovery surface behind `TrackedAssetLock.eligibleFromNative` deliberately admits only funding types 0..2 — so a stalled shielded top-up was invisible everywhere. - Swift `isVisibleAsResumable` / `canFundIdentity` accept 5, and `statusLabel` names it. A `5` carries a real `ChainAssetLockProof`, so it is as fundable as a `3`; what is unknown is Platform-side consumption, and Platform is the arbiter of that. - `IdentitiesContentView.crossWalletResumableLocks` now reuses `isVisibleAsResumable` instead of restating the range inline. `TrackedAssetLock.FundingType` is deliberately NOT widened to funding types 4/5. That enum is the identity-recovery eligibility filter, and its consumers assert on it (`IdentityRegistration` requires IDENTITY_REGISTRATION, `IdentityCredits` requires the two top-up variants). Admitting address/shielded locks there would push them into pickers whose `require(...)` then throws — a new crash path, not a fix. The address/shielded recovery surface is the DAO query above. Tests: 7 new Robolectric Room tests pinning both ends of the domain (5 in, 4 out, 0 out, funding-type and wallet scoping intact), plus a Swift case asserting status 5 is resumable.

…t thread Two unbounded waits on the asset-lock recovery path could never terminate, and both are reached from FFI entry points that drive the future with `runtime().block_on(...)` — so neither merely delays a result, each pins the calling host thread for good. 1. Already-consumed reconciliation (#4357 regression) `reconcile_asset_lock_submit_result` upgrades an Instant proof via `upgrade_to_chain_lock_proof(out_point, chain_lock_timeout)`, and all three production call sites (`identity/network/registration.rs` x2, `platform_addresses/fund_from_asset_lock.rs`) pass `None`. The `None` arm of `wait_for_chain_lock` loops forever waiting on SPV lock events. The trigger is routine rather than exotic: an IS-locked lock consumed seconds after broadcast draws the unauthenticated "already consumed" report while its ChainLock is still ~2.5 minutes out — and never arrives at all when the device is offline or SPV is not connected. Pre-#4357 this path returned a typed error immediately. `None` now selects `RECONCILIATION_CHAIN_LOCK_TIMEOUT` (180s). The ChainLock here is wanted only as evidence to record alongside a report about an operation that has ALREADY terminated, so failing to get it degrades instead of propagating: the lock keeps its current status and the typed `AssetLockAlreadyConsumed` is still returned, preserving the code-24 signal hosts branch on. #4357's proof retention is unchanged whenever the ChainLock is reachable inside the bound. 2. Resume after an ambiguous re-broadcast (#4367 regression) A `MaybeSent` verdict on a `Built` lock advances it to `Broadcast` and waits for a proof. But `MaybeSent` is also the NORMAL verdict for a genuinely rejected transaction — `DapiBroadcaster` classifies every failure that way by construction, and the SPV broadcaster reaches `Rejected` only on `NotConnected` (no BIP61 in modern Dash). So the advance is not evidence the transaction is live, and the following `wait_for_proof(None)` at the `resume_asset_lock(.., None)` call sites turned a ~30s broadcast failure into a wait that never ends, because no proof can arrive for a transaction that was never accepted. The advance is kept (it is what stops each recovery pass repeating the same broadcast), but when the caller asked for an unbounded wait the proof wait is bounded by `UNCONFIRMED_BROADCAST_PROOF_TIMEOUT` and its expiry is translated back into the `TransactionBroadcastUnconfirmed` callers used to get promptly. Callers that supplied their own timeout are untouched, `FinalityTimeout` and all — the shielded seed pool treats that error as a pacing signal, so re-typing it for everyone would break a working flow to fix a different one. Also on the `Broadcast` arm: a definite `Rejected` is no longer swallowed. That arm logged every broadcast error and fell through to `wait_for_proof`, which is right for the ambiguous verdict but guarantees a dead wait for a verdict that means the send provably did not happen. It now surfaces the error and drops the row via the new `untrack_unproven_broadcast_asset_lock`, so cleanup is not lost and a later resume does not re-enter the same wait. That untrack is a separate method rather than a widening of `untrack_asset_lock`. The existing method's caller in `build.rs` uses "the row was removed" as its trigger to RELEASE the funding-input reservation, and deliberately spares rows that advanced to `Broadcast` concurrently because that is evidence the transaction reached the network. Teaching it to remove `Broadcast` rows would release reservations for inputs whose transaction may be live — a double-spend opening. The new method releases no reservation, and guards on `proof.is_none()` plus the `Consumed` terminal state from #4347. Tests: 5 new cases. The two hang regressions are pinned with `start_paused` runtimes and were confirmed to hang the test binary indefinitely when the fixes are reverted.

📝 Walkthrough

Walkthrough

Asset-lock recovery now includes RecoveredFromChain and shielded top-ups across the Kotlin and Swift SDKs. Rust recovery adds bounded proof waits, preserves tracked rows after uncertain broadcasts, and handles local finality proofs. Shielded funding coordination now uses operation identities.

Changes

Asset-lock recovery and SDK resumability

Layer / File(s)	Summary
Resumable query and routing contracts `packages/kotlin-sdk/...`, `packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/...`	DAO queries and SDK filters include statuses `1–3` and `5`. Kotlin and Swift flows observe address and shielded top-ups, route by funding type, and label `RecoveredFromChain`.
Shielded resume flow `packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/navigation/...`, `packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/shielded/ShieldedFundScreen.kt`	Shielded navigation accepts an optional lock outpoint. Resume mode loads the tracked lock, displays its state, validates the outpoint, and calls the resume funding API.
Operation identity coordination `packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/services/shielded/...`, `packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Services/...`	Funding controllers track operation IDs. Coordinators reuse matching operations, block different in-flight operations, and protect replacement controllers during retention sweeps.
Reconciliation timeouts `packages/rs-platform-wallet/src/wallet/asset_lock/orchestration.rs`	Consumed-lock reconciliation bounds ChainLock proof acquisition and preserves `AssetLockAlreadyConsumed` with unchanged lock state after promotion failures.
Broadcast recovery transitions `packages/rs-platform-wallet/src/wallet/asset_lock/sync/...`, `packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs`	Built, Broadcast, and RecoveredFromChain recovery paths use state-dependent timeouts, retain tracked rows, and complete from local finality proofs. FFI documentation reflects the recovery policy.

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

…remaining resume waits Both behaviors this PR's first revision introduced on `resume_asset_lock`'s `Broadcast` arm were defective as shipped. 1. `Rejected` is not evidence about the row The arm dropped an unproven `Broadcast` row when the defensive re-broadcast returned `BroadcastError::Rejected`, on the premise that the verdict proves the transaction never reached the network. It does not. With the production `SpvBroadcaster`, `Rejected` is reachable from exactly two places — a client that was never started (`spv/runtime.rs:222`) and dash-spv's zero-connected-peers check (`:125`) — so it is a statement about the attempt that just failed, never about the ORIGINAL broadcast that moved the row to `Broadcast` in an earlier process. That made the untrack routinely destructive. `catchUpStuckAssetLocks` runs on every wallet load, selects `statusRaw < 2` (which includes `Broadcast` = 1) and has no SPV-connected gate, so an ordinary offline relaunch deleted the tracking row for an asset lock that may well be mined — with no way back, because reconstruction re-inserts only on a FRESH detection event, which an already-recorded mined transaction never produces again. The row is now left exactly as it was and the typed error is surfaced. No state on this path makes non-dispatch of the original send provable (a row can sit at `Built` after a successful broadcast too, when the app died between the send and the status advance), so `untrack_unproven_broadcast_asset_lock` has no justified caller and is removed rather than left loaded. 2. The `Broadcast` arm's proof wait was still unbounded The first revision bounded only the `Built` arm. Its own retained behavior — advance an ambiguous `Built` lock to `Broadcast` and leave the row there — routes exactly that lock into the `Broadcast` arm on the next resume pass, where a bare `wait_for_proof(out_point, timeout)` with `timeout = None` waits on `Notify` forever. The hang was deferred by one pass, not removed, and under the FFI's `runtime().block_on(...)` it pins the host thread for good. Both remaining waits now substitute `UNCONFIRMED_BROADCAST_PROOF_TIMEOUT` when the caller asked for an unbounded one: - `Broadcast`: expiry is re-typed to `TransactionBroadcastUnconfirmed` and the row is left at `Broadcast`. The bound costs nothing — a proof that lands after it is returned by the next resume on `wait_for_proof`'s first iteration, straight from the record. - `RecoveredFromChain`'s proof-less fallback: bounded for uniformity. Its "resolves immediately by construction" argument holds only while the chain-locked record is reachable, and the accident that loses a row's persisted proof can take the record with it. `FinalityTimeout` is kept there — nothing is broadcast on that path. Callers that supply their own timeout are unchanged in both arms (`or` is the identity on `Some`; the re-typing is gated on `timeout.is_none()`), so the shielded seed pool keeps reading `FinalityTimeout` as a pacing signal. The `Built` arm's `Ok`-verdict wait stays unbounded: `Ok` is the broadcaster's positive network-acceptance contract for a send that just happened, the same evidence the initial funding path waits on. Tests: 3 new cases, 1 rewritten, 1 removed. Each new case was confirmed against its defect — both bound regressions hang the test binary indefinitely when the bound is reverted, and the untrack case fails with `left: None, right: Some(Broadcast)` when the untrack is restored.

Both of the F3 behaviors I added in the first revision of this PR were defective. Fixed in c017d88.

F3(c) — untracking a Broadcast row on a rejected re-broadcast was wrong, and routinely destructive.

I justified it with "the broadcaster only reaches Rejected when the send provably did not happen." That's true of the attempt, and I wrongly carried it over to the row. With the pinned SpvBroadcaster, Rejected comes from exactly two places — an unstarted client (spv/runtime.rs:222) and dash-spv's zero-connected-peers check (:125) — so it proves this call never left the device and says nothing about the original broadcast that moved the row to Broadcast, possibly in a process days earlier.

That made it a data-loss path on a completely ordinary flow. catchUpStuckAssetLocks runs on every wallet load, selects statusRaw < 2 (which includes Broadcast = 1), and has no SPV-connected gate — so an offline relaunch deleted the tracking row for an asset lock that may well be mined. There's no recovery: reconstruct_asset_locks_for_event re-inserts only on a fresh detection event, which an already-recorded mined transaction never generates again.

The arm now surfaces the typed error and leaves the row exactly as it was. I looked for a state where non-dispatch of the original send is provable and there isn't one on this path — a Built row can equally have been broadcast successfully before the app died mid-advance, which is why that arm never untracked either. So untrack_unproven_broadcast_asset_lock has no justified caller and I removed it outright rather than leave it available; tracking.rs carries a note explaining why the companion doesn't exist.

F3(a) — I bounded only the Built arm, which deferred the hang by one pass instead of removing it.

The behavior I deliberately kept — advance an ambiguous Built lock to Broadcast, leave the row there — routes that same lock into the Broadcast arm on the next resume, where the bare wait_for_proof(out_point, timeout) with timeout = None is an unbounded Notify loop. Under runtime().block_on(...) that pins the host thread permanently. Both remaining waits now take the same bound:

Broadcast: timeout.or(Some(UNCONFIRMED_BROADCAST_PROOF_TIMEOUT)), expiry re-typed to TransactionBroadcastUnconfirmed, row left at Broadcast. The bound is cheap — a proof arriving after it is returned by the next resume on wait_for_proof's first iteration, straight from the record.
RecoveredFromChain's proof-less fallback: same bound, and it is not just uniformity. Reverting it hangs the new test indefinitely. The "resolves immediately by construction" reasoning holds only while the chain-locked record is reachable, and whatever loses a row's persisted proof can lose the record too. FinalityTimeout is kept there since nothing is broadcast on that path.

Callers passing their own timeout are untouched in both arms (or is the identity on Some; the re-typing is gated on timeout.is_none()), so the shielded seed pool keeps reading FinalityTimeout as its pacing signal. The Built arm's Ok-verdict wait stays unbounded on purpose: Ok is the broadcaster's positive network-acceptance contract for a send that just happened, the same evidence the initial funding path waits on. That's the one unbounded wait left here.

Reachability caveat. The None that triggers these hangs comes from the three in-repo Rust call sites (identity/network/registration.rs:197, :454, platform_addresses/fund_from_asset_lock.rs:190). The FFI's timeout_secs == 0 → None mapping is a second door, and I could not confirm whether anything drives it: both Swift wrappers default to 300 and catchUpStuckAssetLocks passes 300 explicitly, and the Kotlin SDK has no binding for either entry point in this repo. Android's usage is outside what I can check here — if any caller there passes 0, it hits the same mapping.

Tests: 3 new, 1 rewritten, 1 removed. Each new case was confirmed against its defect, not just observed green — the two bound regressions hang the test binary when the bound is reverted, and the untrack case fails left: None, right: Some(Broadcast) when the untrack is restored. Full suite 844 unit + 9 integration green; fmt and clippy clean.

Preliminary review — Codex only

The recovery timeout and tracking changes are sound, but the newly added shielded resumable query is not consumed by any production host surface, so funding-type 5 locks remain inaccessible after restart. The Kotlin address-top-up UI also mishandles the newly exposed RecoveredFromChain rows, and the FFI documentation still promises an unbounded zero-timeout wait that is now state-dependent.

- [BLOCKING] packages/kotlin-sdk/sdk/src/main/kotlin/org/dashfoundation/dashsdk/persistence/dao/AssetLockDao.kt:100-108: The shielded resumable query has no production consumer
  This new query is called only by its Room tests, so adding it does not make funding-type 5 locks visible or resumable. The Kotlin production UI still calls `observeResumableAddressTopUps`, which is fixed to funding type 4, and `ShieldedFundScreen` only starts fresh funding; it never receives an existing lock or invokes `shieldedResumeFundFromAssetLock`. The Swift host has the same gap: `PendingPlatformFundFromAssetLocksList` filters for funding type 4, while `WalletDetailView` constructs `ShieldedFundFromAssetLockView` without `resumeFromLock`. Consequently, a stalled or RecoveredFromChain shielded top-up remains absent from every production recovery surface after restart, which leaves the PR's stated shielded invisibility defect unresolved. Wire funding-type 5 rows into a host list and route its Resume action through the existing shielded resume API on both supported hosts.

- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/funding/AssetLockDisplay.kt:24-47: Kotlin still treats RecoveredFromChain as non-resumable and proofless
  `observeResumableAddressTopUps` now returns status 5 rows to the Kotlin pending-top-up UI, but these shared display predicates still recognize only statuses 1 through 3. A recovered row therefore renders as `Unknown(5)`, and `FundFromAssetLockScreen` takes the `canFundIdentity == false` branch and says it is waiting for finality even though RecoveredFromChain denotes proven Core finality and normally carries a chain proof. Match the updated Swift mapping by admitting status 5 in both predicates and naming it in `statusLabel`; update the existing display tests accordingly.

In `packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs:61-63: Update the zero-timeout FFI contract to match the new bounded policy
  The FFI comments for both `asset_lock_manager_resume` and `asset_lock_manager_catch_up_blocking`, plus the latter's Rustdoc, still say that `timeout_secs == 0` waits indefinitely. This PR makes `None` state-dependent: Built plus MaybeSent, every Broadcast lock, and a proofless RecoveredFromChain lock now use the 180-second internal bound, while only a Built lock whose re-broadcast returns `Ok` retains an unbounded proof wait. A caller passing the documented zero sentinel can therefore receive `TransactionBroadcastUnconfirmed` or `FinalityTimeout` after 180 seconds. Keep the bounded behavior, but document zero as selecting the recovery policy's state-dependent default rather than promising an unconditional infinite wait.

…otlin display predicates `AssetLockDisplay.kt` still described the status domain as `0/1/2/3/4` and treated it as an ordered scale, so status `5` (RecoveredFromChain) fell through every branch: * `statusLabel` rendered it as "Unknown(5)". * `canFundIdentity` was false, which routes the resume screen's copy into the "still awaiting InstantSend / ChainLock finality" branch — telling the user to wait for a finality that is already PROVEN. The restore scan and the chainlock-promotion path attach a real `ChainAssetLockProof` before writing `5`; what is unknown is Platform-side consumption, and Platform is the arbiter of that, rejecting an already-spent outpoint with a typed error. * `isVisibleAsResumable` was `1..3`, which disagreed with the DAO query's `[1,3] ∪ {5}` predicate — so a row the database was willing to return could still be dropped by the Kotlin surface reading it. Aligns all three with `PersistentAssetLockDisplay.swift`, which already made these three calls the same way. The Consumed (`4`) exclusion is now written by name rather than as an upper bound of `3`, since `5` sits above it numerically while being very much alive — the file header says so explicitly so the next reader doesn't "simplify" it back into a range. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

The funding-type-parameterized resumable query added earlier in this branch had no production caller on either host, so the gap it was meant to close stayed open: a stalled or RecoveredFromChain shielded top-up (`fundingTypeRaw == 5`) was still absent from every recovery surface in both apps. * Kotlin: `IdentitiesHomeScreen` called `observeResumableAddressTopUps`, which hardcodes `fundingTypeRaw = 4`. `ShieldedFundScreen` could only start a fresh shield. * Swift: `PendingPlatformFundFromAssetLocksList` filtered `== 4`, and `WalletDetailView` always presented the platform-ADDRESS resume view — `ShieldedFundFromAssetLockView.resumeFromLock` was fully wired to `shieldedResumeFundFromAssetLock` but never constructed with a lock. Neither type has any other home: the identity surfaces admit only funding types `0..2`, and `3` is an invitation voucher owned by the reclaim flow. So a type-5 row was unreachable from anywhere in either app, and read to the user as lost funds. Both halves are needed. Surfacing the row without routing it only moves the dead end one tap later: types 4 and 5 consume their locks through DIFFERENT transitions (`resumeFundFromAssetLock` vs. the Type 18 `shieldedResumeFundFromAssetLock`), so a shielded lock sent to the address screen would submit the wrong transition against it. Kotlin: * `ResumableTopUps.kt` — `resumableTopUpsAcrossWallets` fans the DAO out over both top-up funding types per wallet, and `resumeRouteFor` maps a row to its matching resume screen, fail-closed on anything else. Both are pure so the wiring is assertable without Room or a Compose runtime, which is exactly what the DAO-level test could not cover. * `ShieldedFundScreen` gains resume mode, mirroring `FundFromAssetLockScreen`: hides Amount, shows the tracked lock, and dispatches to `shieldedResumeFundFromAssetLock`. It shares the shielded coordinator with fresh shields on purpose — both consume the same per-wallet `shield_guard` Rust-side, so a resume racing a fresh shield has to hit the same gate. The outpoint parse happens before the coordinator claims the slot. Swift: * The list's funding-type + status predicate is extracted as a pure `nonisolated static` generic over `AssetLockResumeRow` (same shape as `IdentitiesContentView.crossWalletResumableLocks`) and widened to admit both top-up types. * `WalletDetailView`'s resume sheet branches on funding type, finally constructing `ShieldedFundFromAssetLockView(wallet:resumeFromLock:)`.

…ot an unbounded wait Both asset-lock sync entry points still documented `timeout_secs == 0` as requesting an unbounded wait, justified by "a ChainLock is guaranteed finality; a broadcast lock is pending, never failed". That contract no longer holds, and the reasoning behind it was the bug this branch fixed: on a RESUME the broadcaster cannot establish that the transaction is live at all — `DapiBroadcaster` classifies every failure as `MaybeSent`, and the SPV broadcaster reaches `Rejected` only on `NotConnected` — so a rejected transaction is indistinguishable from an accepted one. `resume_asset_lock` now substitutes the 180s `UNCONFIRMED_BROADCAST_PROOF_TIMEOUT` on every arm that actually waits. Zero therefore means "decline to specify a bound; apply the recovery policy's state-dependent default", which is the opposite of what a caller reading these docs would plan for. `asset_lock_manager_catch_up_blocking` made the stale promise load-bearing: it explicitly told callers the thread parks "indefinitely" at zero, and that entry point is fanned out one call per stuck lock at launch. Documents the real contract at both entry points — which stages consult the timeout at all, what zero selects, that expiry is non-destructive (the row stays tracked, the next resume returns a late proof straight from the record), and that a non-zero timeout keeps its exact semantics. Docs only; no behavior change. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Both body suggestions taken (a21c55c + 6f4506c).

AssetLockDisplay.kt — added the status-5 label and routed it to the fundable branch (canFundIdentity now {2, 3, 5}), matching PersistentAssetLockDisplay.swift, which already made both calls that way.

I went one step further than the suggestion and also widened isVisibleAsResumable from 1..3 to [1,3] ∪ {5}. At 1..3 the Kotlin predicate disagreed with the DAO query's own recoverable set, so a row the database was willing to return could still be dropped by the surface reading it — a second, quieter instance of the same bug. The Consumed exclusion is now written by name rather than as an upper bound of 3, with a note in the file header, since 5 sits above 4 numerically while being very much alive and the range form reads as equivalent. Tests updated, including one that pins specifically that the exclusion is not a bound.

rs-platform-wallet-ffi/src/asset_lock/sync.rs — both entry points now document zero as "decline to specify a bound; the recovery policy applies its state-dependent default", which today is the 180s UNCONFIRMED_BROADCAST_PROOF_TIMEOUT on every arm that actually waits. Each also documents which stages consult the timeout at all, that expiry is non-destructive (the row stays tracked; the next resume returns a late proof straight from the record), and that a non-zero timeout keeps its exact FinalityTimeout semantics.

catch_up_blocking was the worse of the two — it explicitly promised callers the thread parks "indefinitely" at zero, and that entry point is fanned out one call per stuck lock at launch, so the stale promise was load-bearing. Docs only, no behavior change. Swift wrappers checked (ManagedAssetLockManager.resume/catchUpBlocking, PlatformWalletManager.runCatchUp): all pass explicit non-zero timeouts, so no host-side doc inherited the stale contract.

Final validation — Codex/Sol only (Phase 2 disabled)

The current head fixes the two prior host-surface findings: shielded locks now have production resume routes on Kotlin and Swift, and Kotlin correctly recognizes RecoveredFromChain. Three in-scope issues remain: shielded resume coordination can conflate distinct outpoints, reconciliation suppresses non-timeout internal errors, and the zero-timeout FFI documentation still overstates the bounded policy.

- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/shielded/ShieldedFundScreen.kt:303-307: Shielded resume single-flighting ignores the asset-lock outpoint
  The resume closure captures one specific outpoint, but the coordinator is keyed only by wallet and recipient. `startFunding` returns an existing controller without invoking the new closure when that slot is InFlight or Completed. Because resumable locks normally default to the same wallet-owned shielded recipient, tapping a second lock while the first is running—or during its 30-second completed retention period—shows the first operation and never calls `shieldedResumeFundFromAssetLock` for the second outpoint. A fresh shield to the same recipient can suppress a resume in the same way. Swift has the same collision in `ShieldedFundFromAssetLockCoordinator`. Include the outpoint or another operation identity in resume deduplication, while retaining wallet-wide serialization, or report a distinct same-recipient operation as blocked instead of reusing its controller. Add coverage for two resumable locks sharing the default recipient.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/asset_lock/orchestration.rs:479-496: Only downgrade the expected ChainLock timeout
  This newly added match converts every `upgrade_to_chain_lock_proof` failure into the expected already-consumed result. Only `FinalityTimeout` means that the ChainLock did not arrive within the new policy bound. The method can also return `WalletNotFound` and `AssetLockProofWait` for a missing tracked lock, inconsistent wallet state, or persister lookup failure. Suppressing those failures misreports a local recovery failure as `AssetLockAlreadyConsumed`, sending the host down its code-24 path even though reconciliation could not inspect the required state. Downgrade only `FinalityTimeout`, propagate other typed errors, and narrow the surrounding documentation to the timeout case.

In `packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs:53-64: Update the zero-timeout FFI contract to match the new bounded policy
  The updated ABI documentation now claims that every proof-waiting arm substitutes the 180-second bound and that catch-up is bounded in all cases. `resume_asset_lock` explicitly retains one exception: when a Built lock's re-broadcast returns `Ok`, `maybe_sent_reason` is `None`, the wildcard branch forwards the original `timeout == None` to `wait_for_proof`, and that wait remains unbounded. Because both FFI functions run this future through `runtime().block_on`, a caller relying on the documented guarantee can still park its host thread indefinitely on this branch. Document zero as selecting a state-dependent policy: ambiguous Built broadcasts, Broadcast rows, and proofless RecoveredFromChain rows receive the 180-second default, while a Built re-broadcast positively accepted by the broadcaster retains an unbounded wait. Update the duplicated inline comments and catch-up Rustdoc consistently.

…ion, not just the recipient The shielded fund coordinators (Kotlin + Swift) deduplicate by (walletId, recipientRaw43), but resumable locks normally default to the same wallet-owned shielded recipient, so two different locks share one slot key. startFunding returned the FIRST lock's controller for an InFlight/Completed slot without invoking the new closure — tapping a second resumable lock while the first was running (or within its 30s completed-retention window) silently showed the first operation and never called shieldedResumeFundFromAssetLock for the second outpoint. A fresh shield to the same recipient could suppress a resume the same way. Reuse now additionally requires a matching operation identity (the resumed lock's outpoint, or the fresh-shield marker): - same operation: reuse, unchanged single-flight; - different operation, slot InFlight: BlockedByOtherWalletFunding — the wallet-wide shield serialization verdict, same as a different recipient; - different operation, slot Completed: a fresh start — the retained controller is replaced, and retention sweeps are identity-guarded so the old controller's timer cannot evict the replacement. Adds Kotlin coordinator coverage for two resumable locks sharing the default recipient (blocked while in flight, started during the completed-retention window, sweep does not evict the replacement).

…ro-timeout bound claim The resume/catch-up ABI docs claimed timeout_secs == 0 substitutes the 180s UNCONFIRMED_BROADCAST_PROOF_TIMEOUT on every proof-waiting arm, so the block_on'd host thread is parked for a bounded time in all cases. resume_asset_lock retains one deliberate exception: a Built lock whose re-broadcast the broadcaster positively ACCEPTED (Ok, not MaybeSent) forwards the original None to wait_for_proof and keeps the unbounded positive-evidence wait the initial funding path performs after its own successful broadcast. Document zero as selecting a state-dependent policy: ambiguous Built re-broadcasts, Broadcast rows, and the proof-less RecoveredFromChain fallback get the 180s default; an accepted Built re-broadcast waits for the transaction's proof (its ChainLock, ~2.5min in normal operation) without a hard bound — callers that need one pass a non-zero timeout_secs. The launch fan-out safety argument is narrowed to match: an unconnected/undeliverable broadcast reports Rejected/MaybeSent, never Ok, so offline devices only take the bounded arms. Both duplicated inline comments and the catch-up Rustdoc updated consistently. Documentation only; no behavior change. Addresses review finding d67117741b2a.

…re to code-24 The catch-all Err arm in reconcile_asset_lock_submit_result reads as if it accidentally swallows WalletNotFound / AssetLockProofWait alongside the expected FinalityTimeout. It is deliberate: the already-consumed classification comes from Platform's outpoint-matched consensus error, not from the local ChainLock-promotion lookup, so a failed lookup does not invalidate it — and the non-timeout failures occur precisely in the degraded-local-state scenarios (lock untracked after a restore, persister failure) where the host's code-24 branch is the only path that can still resolve the operation from Platform-side evidence. Recording-path failures still propagate. Documentation only; no behavior change. Addresses review finding 9237664c50df (declined — rationale on the thread).

One non-blocking test-coverage gap remains: the newly documented catch-all downgrade is exercised only through its timeout case, so its degraded-local-state behavior is not pinned.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/asset_lock/orchestration.rs:486-501: Pin the deliberate non-timeout reconciliation downgrade with a test
  This catch-all deliberately makes `WalletNotFound` and `AssetLockProofWait` follow the same code-24 path as `FinalityTimeout`, preserving `AssetLockAlreadyConsumed` after Platform has reported that the exact submitted outpoint was consumed. The added reconciliation regression test exercises only the timeout case; changing this match back to timeout-only handling would therefore leave the suite green while breaking the newly documented degraded-local-state policy. Add a test with an Instant proof and a tracked lock whose transaction record is unavailable, then assert that the resulting `AssetLockProofWait` is downgraded to `AssetLockAlreadyConsumed` and the tracked status remains unchanged.

…owngrade The catch-all Err arm in reconcile_asset_lock_submit_result deliberately downgrades EVERY upgrade_to_chain_lock_proof failure to the code-24 AssetLockAlreadyConsumed signal, but only the outcome was pinned — and by exactly one scenario. Worse, that scenario was not the one its test documented: the built funding tx is never registered as a TransactionRecord and NoopTestPersister keeps the trait's Ok(None) lookup, so the "terminates without a ChainLock" test never reached wait_for_chain_lock at all. It fast-failed with AssetLockProofWait — accidentally covering the non-timeout arm while leaving the timeout arm it described unexercised. Restructure into a shared fixture plus one test per arm, each asserting the promotion's error variant DIRECTLY before checking the downgrade, so the scenarios cannot silently collapse onto the same path: - already_consumed_reconciliation_terminates_without_a_chainlock now registers the funding tx's (mempool, non-chain-locked) record so the promotion genuinely dispatches to wait_for_chain_lock and burns the bound: pinned as FinalityTimeout, then downgraded. - already_consumed_reconciliation_downgrades_non_timeout_promotion_failure (new) keeps the record unavailable — the post-restore degraded-state shape — and pins the AssetLockProofWait fast-fail, then the downgrade with the tracked row untouched. Verified against the feared refactor: narrowing the catch-all to FinalityTimeout-only fails the new test ("must DOWNGRADE to the code-24 signal ... got AssetLockProofWait") while the rest of the suite stays green.

Final validation — Codex/Sol only (Phase 2 disabled)

The prior reconciliation coverage gap is fixed: separate passing regressions now pin both FinalityTimeout and non-timeout AssetLockProofWait promotion failures. One in-scope recovery issue remains: a rejected defensive re-broadcast returns before consulting an authenticated proof already available in the local transaction record. The proposed shielded FFI mapping is not retained because code 26 promises the original transaction is absent and its reservation released, which is explicitly untrue for a rejected defensive re-broadcast.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/asset_lock/sync/recovery.rs:398-410: Check local proof before failing a rejected defensive re-broadcast
  The `Broadcast` arm returns immediately when the defensive re-broadcast is rejected, before `wait_for_proof` performs its first in-memory/persister transaction-record lookup. A tracked row can still be `Broadcast` while its record already contains an InstantSend lock or `InChainLockedBlock` context—for example, finality arrived while no waiter was active or the persisted tracked status was not enriched before startup catch-up. In that state `wait_for_proof` would return an authenticated proof immediately, without waiting, but an offline or unstarted broadcaster suppresses that valid recovery result. The current rejection regression creates no proof-bearing record and therefore misses this case. Probe the existing record before broadcasting, or perform a non-waiting proof lookup after `Rejected`, and surface the broadcast error only when no local proof exists; add a regression using a `Broadcast` row, a proof-bearing transaction record, and `AlwaysRejectedBroadcaster`.

…ive re-broadcast A row can sit at Broadcast while its transaction record already carries finality: LockNotifyHandler only wakes waiters, so an IS/CL event that arrives with no waiter active enriches the record without advancing the tracked status, and enrich_from_record upgrades only chain-locked records on scan paths (an InstantSend context is invisible to it). On the next launch catchUpStuckAssetLocks resumes the row before SPV connects, the defensive re-broadcast draws Rejected (unstarted client / zero connected peers), and the Broadcast arm failed the resume even though wait_for_proof would have returned the proof on its first iteration — straight from the local record, without any network. On Rejected, probe the record once via wait_for_proof with a zero bound (exactly one local record/persister check, expires before touching the network) and complete the resume from the proof when one exists; surface the broadcast error, row untouched, only when the probe finds nothing.

Final validation — Codex/Sol only (Phase 2 disabled)

The prior rejected-rebroadcast finding is fixed: the Broadcast path now performs a zero-duration local proof lookup and has regression coverage for an InstantSend-bearing record. Three non-blocking issues remain in the newly exposed host flows: ambiguous broadcast errors are flattened at the shielded FFI boundary, the Swift resume text misdescribes Broadcast locks, and fixed fresh-shield operation IDs can suppress a second funding attempt on both hosts.

Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:620-630: Preserve the unconfirmed-broadcast code through the shielded FFI
  The new bounded recovery paths can return `PlatformWalletError::TransactionBroadcastUnconfirmed` from both a Built lock with an ambiguous re-broadcast and a Broadcast lock whose proof does not arrive within the internal bound. Both shielded fund-from-asset-lock entry points pass their result through this mapper, whose catch-all converts that variant to `ErrorWalletOperation` (6). Swift and Kotlin therefore cannot reach their existing typed code-20 handling and lose the essential may-have-broadcast/do-not-retry contract. Preserve `TransactionBroadcastUnconfirmed` through the blanket conversion and add it to the mapper regression. Keep a definite `TransactionBroadcast` generic here: code 26 promises that the original transaction is absent and its reservation was released, which a rejected defensive re-broadcast does not establish.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockView.swift:550-553: Describe Broadcast shielded resumes as waiting for finality
  The new resumable-top-up routing sends status-1 Broadcast shielded locks into this view, but the footer always says that the lock already has a usable proof. It also asks the user to choose a shield amount even though resume mode hides the amount field and Rust derives the value from the existing lock. Branch on `canFundIdentity` so Broadcast rows explain that Resume will first wait for InstantSend or ChainLock finality, while proof-ready statuses retain the immediate-completion message.
- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockView.swift:690: Use a distinct operation identity for each fresh shield
  The new coordinator treats an equal operation ID as the same operation and returns a retained InFlight or Completed controller without invoking the supplied body. Every fresh Swift shield uses `"shield"`; after completion, the enabled Cancel action can dismiss the sheet without removing the controller, so another fresh shield to the same recipient within the 30-second retention window only reopens the old result. The Kotlin sibling has the same fixed marker at `ShieldedFundScreen.kt:299`; backing out of its completed progress screen leaves the original funding form and retained controller available, so resubmission is suppressed there too. Give each fresh user attempt a unique identity while keeping `resume:<outpoint>` stable for resumed locks. Swift can store a UUID for each presented view; Kotlin should rotate a remembered attempt token after an accepted start so returning to the same navigation entry can initiate another funding.

The round-4 single-flight keyed controller reuse by (slot, operationId), but both hosts passed a fixed "shield" marker for every fresh shield. Within the coordinator's ~30s completed-retention window, a second fresh shield to the same recipient matched the retained controller's operation id and rebound to the old Completed state — the new FFI body never ran (Swift: dismiss the completed sheet and shield again; Kotlin: back out of the completed progress route and resubmit the form). Fresh shields now mint "shield:<uuid>" at submission time in both call sites (ShieldedFundFromAssetLockView.swift, ShieldedFundScreen.kt), so every fresh user attempt is a distinct operation: blocked while another is in flight, a genuine replacement once the slot has completed. "resume:<outpoint>" stays stable so a re-tap of the same lock still rebinds to its controller. Coordinator docs updated in both hosts; two Kotlin coordinator regression tests pin the replacement (body runs, controller replaced, sweep hand-off) and the in-flight block.

Final validation — Codex/Sol only (Phase 2 disabled)

The core recovery changes are internally consistent, but four non-blocking host-surface issues remain: the shielded FFI flattens the new unconfirmed-broadcast result, Swift misdescribes Broadcast resumes, and the Swift and Kotlin progress views misreport newly reachable resumed states. The prior fresh-shield operation-identity issue is fixed at this head; no blocking issue remains.

  This PR newly routes status-5 `RecoveredFromChain` locks into the shielded resume flow, but both phase switches fall through to step 1 for that status. `resume_asset_lock` deliberately preserves `RecoveredFromChain` after refreshing its already-available ChainLock proof, so during the potentially long Halo 2 build the UI incorrectly reports “Building asset-lock transaction.” Handle status 5 like the ChainLocked case in both `.inFlight` and `.failed`, advancing to the shielding step and marking the InstantSend lane skipped.

  The new Kotlin resume route can start from a status-1 Broadcast lock, where the FFI may spend up to the recovery bound waiting for InstantSend or ChainLock finality. `Phase.InFlight` nevertheless maps unconditionally to index 2, marking both the transaction-build and finality-wait steps complete and showing Orchard shielding as active for the entire call. A finality timeout is likewise displayed as a shielding-stage failure because `Phase.Failed` also maps to index 2. Carry the resumed outpoint or current asset-lock status into this progress model so Broadcast resumes remain on the proof-wait step until the persisted row becomes proof-ready; proof-ready statuses can advance directly to shielding.

Preliminary review — Codex only

The recovery changes preserve tracked locks and bound the intended ambiguous waits, but the rejected defensive re-broadcast path now exposes a definitive, retry-safe error even though the original transaction may still be live and its reservation remains held. That fund-safety contract violation is blocking; six additional FFI and host-presentation issues remain non-blocking.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/asset_lock/sync/recovery.rs:415-441: Do not classify a rejected defensive send as rejection of the original transaction
  This `Broadcast` row records an earlier broadcast attempt. A `Rejected` result here proves only that the current defensive re-broadcast did not leave the device; it does not establish that the original transaction is absent from the network. Converting the result with `e.into()` produces `PlatformWalletError::TransactionBroadcast`, which public FFI paths map to code 26. That code explicitly promises that Core rejected the transaction, its UTXO reservation was released, and rebuilding is safe. This branch deliberately keeps both the row and its reservation because the original transaction may still confirm. A conforming host can therefore rebuild using other available UTXOs and create a second asset lock while the original remains live. Return `TransactionBroadcastUnconfirmed` so callers receive the code-20 do-not-retry contract.

- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:778-785: Preserve the unconfirmed-broadcast code through the shielded FFI
  The bounded recovery paths can return `PlatformWalletError::TransactionBroadcastUnconfirmed` when an ambiguous `Built` re-broadcast or an existing `Broadcast` lock reaches the internal proof deadline. Shielded resume sends that result through this mapper, but the catch-all converts it to `ErrorWalletOperation` (6), even though the blanket conversion maps it to the dedicated `ErrorTransactionBroadcastUnconfirmed` (20). Swift and Kotlin consequently cannot reach their existing may-have-broadcast, do-not-retry handling. Preserve this variant and add it to the mapper regression. Keep a definite `TransactionBroadcast` generic here until the defensive rejection path is correctly reclassified, because code 26 promises that the original transaction was absent and its reservation released.
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:1683-1714: Contain panics in the newly routed shielded resume export
  This PR gives both example hosts production routes to `platform_wallet_manager_shielded_resume_fund_from_asset_lock`, but the export invokes `block_on_worker` outside `catch_funding_panic`. If recovery, proving, signing, or submission panics, `block_on_worker` re-panics at its `expect("tokio worker panicked")`. On Android's unwind profiles that panic reaches the non-unwinding C ABI frame and aborts before the outer JNI guard can intercept it; callers receive no typed result. The CoinJoin-drain sibling already splits its implementation into an ordinary Rust function and runs it under `catch_funding_panic` for this reason. Apply the same structure here and map a caught panic to code 20 because the resumed asset lock may already have been submitted. The iOS profiles remain abort-on-panic by workspace policy, so this containment specifically fixes unwind-profile hosts.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockView.swift:547-553: Describe Broadcast shielded resumes as waiting for finality
  The resumable-top-up route admits status-1 `Broadcast` shielded locks, but this footer says every routed lock already has a usable proof. A status-1 resume can spend the recovery interval waiting for InstantSend or ChainLock finality. The text also asks the user to choose a shield amount even though resume mode hides that input and Rust derives the amount from the tracked lock. Branch on `lock.canFundIdentity`: proof-ready statuses 2, 3, and 5 should ask only for a recipient, while status 1 should explain the finality wait.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockProgressView.swift:116-145: Treat RecoveredFromChain as proof-ready in shield progress
  This PR routes status-5 `RecoveredFromChain` locks through shielded resume, but both phase switches still send status 5 through the default branch to step 1. Rust deliberately preserves `RecoveredFromChain` after validating or refreshing its existing ChainLock proof, so the row remains status 5 while the potentially long Halo 2 build runs. The UI therefore reports “Building asset-lock transaction” instead of shielding. Handle status 5 like `ChainLocked` in both `.inFlight` and `.failed`; the existing `step3WasSkipped` predicate already gives it the correct ChainLock finality lane.

  A newly routed status-1 `Broadcast` resume can spend the recovery interval inside the blocking FFI call waiting for InstantSend or ChainLock finality. `reachedStep` nevertheless maps every `Phase.InFlight` and `Phase.Failed` to index 2, which marks both transaction construction and proof waiting complete and presents Orchard shielding as active. A finality timeout is consequently rendered as a shielding-stage failure as well. Carry the resumed outpoint or its current persisted asset-lock status into this progress model so status 1 remains on the proof-wait step until persistence reports a proof-ready status; statuses 2, 3, and 5 can advance directly to shielding.

In `packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs:219-228: Preserve the unconfirmed-broadcast code through catch-up
  `asset_lock_manager_catch_up_blocking` delegates to the same `resume_asset_lock` operation and documents the same state-dependent zero-timeout policy as `asset_lock_manager_resume`. When an implicit recovery bound expires, the core can return `TransactionBroadcastUnconfirmed`, but this catch-all always converts it to `ErrorWalletOperation` (6). Public callers using the documented zero-timeout policy therefore cannot observe code 20's may-have-broadcast, do-not-retry result through catch-up. Preserve that variant through the blanket conversion while leaving ordinary caller-supplied timeouts and unrelated failures generic.

…ection of the original tx The `Broadcast` arm of `resume_asset_lock` re-broadcasts defensively before waiting for a proof. When that attempt came back `Rejected` and the local record held no proof, the resume converted the broadcaster error with `e.into()`, producing `PlatformWalletError::TransactionBroadcast` — the FFI's code 26, which promises the host that Core rejected the transaction, that its UTXO reservation was released, and that rebuilding is safe. None of that is established here. With the production `SpvBroadcaster`, `Rejected` is reachable only from an unstarted client and dash-spv's zero-connected-peers check, so it means "*this* send never left the device" — it says nothing about the ORIGINAL broadcast that moved the row to `Broadcast` in an earlier process, which may still confirm. That is exactly why this arm keeps both the row and its reservation. A host honouring code 26 would rebuild from other UTXOs and create a second asset lock beside a live one. Return the non-terminal `TransactionBroadcastUnconfirmed` (code 20, do not retry) instead. The zero-bound local-record probe, the row and its reservation are unchanged; definite rejection stays on the `Built` arm, where no prior broadcast exists. This makes the code match the rationale the `untrack_unproven_broadcast_asset_lock` NOTE in `sync/tracking.rs` already records. Addresses the review finding "Do not classify a rejected defensive send as rejection of the original transaction" on #4422. Regression test: `recovery::tests::rejected_defensive_rebroadcast_is_not_a_rejection_of_the_original_transaction` (retargeted from `definite_rejection_on_a_broadcast_lock_surfaces_without_untracking`, which pinned the wrong error type) asserts the resume does NOT surface `TransactionBroadcast`, does surface `TransactionBroadcastUnconfirmed`, and leaves the row tracked at `Broadcast`. Test would have caught this in CI: ✖ before the fix ("...must not claim the definite-rejection contract, got TransactionBroadcast(\"simulated pre-send rejection\")"), ✔ after.

Preliminary review — Codex only

The PR fixes the prior Broadcast-row rejection classification, but the equivalent crash-recovery ambiguity remains for Built rows: a rejected recovery send is still exposed as definitive FFI code 26 even though an earlier send may be live and the tracked lock remains reserved. This fund-safety contract violation is blocking; seven additional in-scope FFI and host-progress issues remain non-blocking.

- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:778-785: Preserve the unconfirmed-broadcast code through the shielded FFI
  Shielded resume passes `resume_asset_lock` failures through this mapper. The new bounded recovery paths, rejected defensive Broadcast re-broadcasts, and the Built recovery fix above can all return `PlatformWalletError::TransactionBroadcastUnconfirmed`, but this catch-all converts that variant to generic `ErrorWalletOperation` (6). The blanket conversion already maps it to dedicated code 20, which Swift and Kotlin interpret as “may have broadcast, inputs remain reserved, do not retry.” Preserve this variant explicitly and extend the mapper regression so the newly exposed shielded resume routes do not lose that safety contract.
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:1628-1714: Contain panics in the newly routed shielded resume export
  This PR gives both example hosts production routes to `platform_wallet_manager_shielded_resume_fund_from_asset_lock`, but the export invokes `block_on_worker` outside `catch_funding_panic`. If recovery, Halo 2 proving, signing, submission, or bookkeeping panics, `block_on_worker` re-panics through `expect("tokio worker panicked")`. Android uses unwind profiles, but that panic reaches the non-unwinding `extern "C"` frame and aborts before the outer JNI guard can catch it. The CoinJoin-drain sibling already splits its body into an ordinary Rust function and wraps it with `catch_funding_panic`. Apply the same structure here and use code 20 because the asset lock or Platform transition may already have been submitted. This containment protects unwind-profile hosts; iOS remains abort-on-panic by workspace policy.

  This PR routes status-5 `RecoveredFromChain` locks through shielded resume, but both `.failed` and `.inFlight` switches send status 5 through the default branch to step 1. Rust validates or refreshes the ChainLock proof while deliberately preserving `RecoveredFromChain`, so the row can remain at status 5 throughout the long Halo 2 proof build and Platform submission. The UI consequently reports “Building asset-lock transaction” while shielding is already underway. Handle status 5 like `ChainLocked` in both switches; the existing `step3WasSkipped` predicate already gives it the ChainLock-finality lane.
- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockProgressView.swift:65-69: Bind shielded resume progress to the resumed outpoint
  The progress query selects every funding-type-5 row for the wallet, and every step calculation reads `activeLocks.first`, which is simply the most recently updated row. The new recovery surface permits multiple resumable shielded locks; resuming an older lock does not remove a newer orphan or consumed row, so that unrelated row can drive all five progress steps. Wallet-wide serialization prevents concurrent submissions but does not make the newest persisted row the operation represented by this controller. The controller already records `operationId = "resume:<outpoint>"`; carry the resumed outpoint into the progress section and select that exact row for resume operations, falling back to the newest type-5 row only for fresh builds.

  `asset_lock_manager_catch_up_blocking` delegates to `resume_asset_lock`, including the new state-dependent bounds selected by `timeout_secs == 0`. An implicit proof deadline or an ambiguous rejected recovery attempt can return `TransactionBroadcastUnconfirmed`, but this catch-all flattens it to `ErrorWalletOperation` (6), bypassing the blanket conversion's dedicated code 20.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/asset_lock/sync/recovery.rs:293-306: Do not classify a rejected Built recovery send as a definitive original rejection
  (existing thread: https://github.com/dashpay/platform/pull/4422#discussion_r3869024977)
  A persisted `Built` row does not prove that the transaction was never sent. The initial funding path queues the Built changeset before broadcasting, so the process can stop after a successful send but before advancing the row to `Broadcast`; the regression immediately below this code documents that exact recovery window. If the restarted SPV broadcaster then rejects the defensive attempt because it is unstarted or has no peers, `rejected.into()` returns `TransactionBroadcast`, which the public FFI maps to code 26. Code 26 promises that Core definitively rejected the transaction, its reservation was released, and rebuilding is safe, but this recovery branch deliberately leaves the row at Built and performs no reservation release because the earlier send may still confirm. A host honoring code 26 can therefore start another asset lock while the original remains live. Return `TransactionBroadcastUnconfirmed`, matching the conservative contract now used by the Broadcast arm, and update `built_resume_still_fails_on_a_definite_rejection` accordingly.

Preliminary review — Codex only

The recovery bounds and row-preservation changes are directionally sound, but rejected recovery of a persisted Built row still emits a definitive, retry-safe rejection even though the original transaction may be live and its reservation remains held. One blocking fund-safety issue and seven non-blocking FFI or host-presentation issues remain at the exact head.

In `packages/rs-platform-wallet-ffi/src/shielded_send.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:778-785: Preserve the unconfirmed-broadcast code through the shielded FFI
  Shielded resume passes `resume_asset_lock` failures through this mapper. The bounded Built and Broadcast recovery paths already return `TransactionBroadcastUnconfirmed`, and the corrected rejected-Built path must do the same, but the catch-all rewrites that variant to generic `ErrorWalletOperation` code 6. The blanket conversion maps it to dedicated code 20, which Swift and Kotlin interpret as “may have broadcast, inputs remain reserved, do not retry.” Preserve the typed variant and add it to the mapper regression so the shielded recovery route retains that fund-safety contract.
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:1628-1714: Contain panics in the newly routed shielded resume export
  This PR gives the example hosts production routes to this resume export, but it invokes `block_on_worker` directly inside the `extern "C"` function. If recovery, Halo 2 proving, signing, submission, or bookkeeping panics, the Tokio task returns a `JoinError` and `block_on_worker` re-panics through `expect("tokio worker panicked")`. On unwind-profile Android builds that panic reaches the non-unwinding C ABI frame and aborts before the outer JNI guard can convert it. Split the body into an ordinary Rust function and invoke it through `catch_funding_panic`, following the CoinJoin-drain sibling; use code 20 because the asset lock or Platform transition may already have been submitted.

In `packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockView.swift`:
- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockView.swift:550-553: Describe Broadcast shielded resumes as waiting for finality
  The resume route admits status-1 Broadcast locks, but this footer says every selected lock already has a usable proof. A Broadcast resume can instead spend the recovery interval waiting for InstantSend or ChainLock finality. The text also asks for a shield amount even though resume mode hides that field and Rust derives the amount from the tracked lock. Branch on `lock.canFundIdentity`: statuses 2, 3, and 5 are proof-ready, while status 1 should explain the finality wait.

In `packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockProgressView.swift`:
- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockProgressView.swift:116-145: Treat RecoveredFromChain as proof-ready in shield progress
  Both the failed and in-flight switches route status 5 (`RecoveredFromChain`) through the default branch to step 1. Rust validates or refreshes the ChainLock proof while deliberately preserving `RecoveredFromChain`, so the row can remain at status 5 throughout Halo 2 proving and Platform submission. The progress UI consequently reports “Building asset-lock transaction” while shielding is already underway. Handle status 5 like ChainLocked in both switches; the existing `step3WasSkipped` predicate already places it in the ChainLock-finality lane.
- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/ShieldedFundFromAssetLockProgressView.swift:55-70: Bind shielded resume progress to the resumed outpoint
  The progress query selects every funding-type-5 row for the wallet, and every step calculation reads `activeLocks.first`, which is merely the most recently updated row. Multiple resumable shielded locks can coexist, and resuming an older lock does not remove a newer orphan or consumed row, so an unrelated row can drive all five progress steps. Wallet-wide serialization prevents concurrent submissions but does not identify which persisted row belongs to this controller. Use the controller's `resume:<outpoint>` operation identity to select the exact row for resume operations, retaining the newest-row fallback only for fresh builds.

In `packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/shielded/ShieldedFundProgressScreen.kt`:
- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/shielded/ShieldedFundProgressScreen.kt:106-110: Keep the proof-wait step active during a Broadcast resume
  A status-1 Broadcast resume can remain inside the blocking native call while Rust waits for InstantSend or ChainLock finality. `reachedStep` nevertheless maps every InFlight and Failed operation to index 2, marking both transaction construction and proof waiting complete and presenting Orchard shielding as active. A finality timeout is therefore rendered as a shielding-stage failure. Carry the resumed outpoint or persisted asset-lock status into this progress model so status 1 remains on the proof-wait step until the row reaches status 2, 3, or 5.

In `packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/asset_lock/sync.rs:219-228: Preserve the unconfirmed-broadcast code through catch-up
  `asset_lock_manager_catch_up_blocking` delegates to `resume_asset_lock`, including the state-dependent bounds selected by `timeout_secs == 0`. An implicit recovery deadline or conservatively classified rejected recovery attempt can return `TransactionBroadcastUnconfirmed`, but this catch-all flattens every failure to `ErrorWalletOperation` code 6. Public callers therefore lose code 20's may-have-broadcast, inputs-reserved, do-not-retry result precisely when the recovery policy needs to communicate it. Preserve that variant through the blanket conversion while keeping unrelated failures generic.

In `packages/rs-platform-wallet/src/wallet/asset_lock/sync/recovery.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/wallet/asset_lock/sync/recovery.rs:293-306: Do not classify a rejected Built recovery send as a definitive original rejection
  (existing thread: https://github.com/dashpay/platform/pull/4422#discussion_r3869024977)
  A Built row is queued for persistence before the initial broadcast, so a process can stop after the original send succeeds but before the row advances to Broadcast. Rejection of this restarted defensive attempt therefore proves nothing about the original send. This branch leaves the Built row and its funding-input reservation intact, but `rejected.into()` produces `TransactionBroadcast`, which the public FFI maps to code 26 and documents as a definitive rejection whose reservation was released and whose payment may safely be rebuilt. A host honoring that contract can create a second asset lock while the original remains live. Return `TransactionBroadcastUnconfirmed` and update `built_resume_still_fails_on_a_definite_rejection` to pin the conservative contract.

All findings from this review are fixed with red-proven regressions and their threads replied+resolved (see thread dispositions); dismissing the stale verdict.
