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) untrack_unproven_broadcast_asset_lock removes Broadcast rows that carry no proof, preserving the #4347 Consumed-terminal guard.

(c) 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 the send provably did not happen. It now surfaces the error and drops the unproven row.

A second deviation, for fund safety. The finding asked to widen untrack_asset_lock itself. I added a separate method instead. untrack_asset_lock's caller in build.rs:954 uses "the row was removed" as its trigger to release the funding-input reservation, and deliberately spares rows a concurrent resume advanced to Broadcast 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 terminal state.

Test evidence

  • cargo test -p platform-wallet --features shielded851 passed, 0 failed, 3 pre-existing ignored.
  • cargo test -p platform-wallet-ffi --features shielded318 passed, 0 failed.
  • :sdk:testDebugUnitTest --tests AssetLockResumableDaoTest7 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 and untracks; the untrack spares proven, Consumed, RecoveredFromChain and Built rows.

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.
  • F3(c) releases no reservation when it untracks a rejected Broadcast row — the resume path holds no reservation token. Conservative: inputs stay reserved until the TTL backstop.

Summary by CodeRabbit

  • New Features

    • Recovered asset locks now appear as resumable and can fund identities.
    • Resumable top-ups can be filtered by funding type, including shielded top-ups.
    • Recovered lock statuses are displayed clearly in the Swift example app.
  • Bug Fixes

    • Asset-lock recovery now handles delayed or missing chain confirmations without hanging indefinitely.
    • Unconfirmed broadcasts are classified more accurately, while proven and terminal locks are preserved.
    • Unproven broadcast locks are safely removed when confirmed invalid.

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.

Merge Risk: 🟠 High · up to 1f06f

The PR bounds previously indefinite waits and restores visibility for recovered locks, but two correctness risks remain: a persistence failure can hide the already-consumed result, and removing an unproven broadcast record after a rejected retry can erase tracking for a transaction that may already have been sent. The latter can lead to unsafe recovery behavior, so the PR is not ready to merge until addressed.

…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.

In `packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/funding/AssetLockDisplay.kt`:
- [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.
