Issue being fixed or feature implemented

A wallet that holds a masternode collateral could spend it in an ordinary send, which ends the masternode registration. key-wallet can now keep such a coin out of coin selection (dashpay/rust-dashcore#1391), but platform-wallet did not persist that lock set, had nowhere to keep it on the mobile hosts, and never locked a collateral whose registration the wallet did not process itself.

This takes over #5113 by QuantumExplorer, which could not be continued in place: its base branch was closed unmerged and it pinned an old rust-dashcore backport. His three commits are kept with his authorship, ported to current v5.1-dev. Supersedes #5113.

Draft until dashpay/rust-dashcore#1391 merges: the rust-dashcore pin points at that PR's branch tip and has to move to the merged dev revision first.

What was done?

Example: a wallet holding its own 1,000 DASH collateral and a 5 DASH coin.

balance:      spendable 5 DASH, locked 1000 DASH
send 1 DASH:  spends the 5 DASH coin
send 6 DASH:  refused, insufficient funds
restart:      the collateral is still locked
unlock_outpoint(collateral), then send 1 DASH: spends the collateral

rs-platform-wallet

• CoreChangeSet::outpoint_locks (true locks, false unlocks, last write wins per outpoint).
• A lock made by a transaction check is stored with the block or transaction that made it: the wallet-event adapter copies locked_outpoints from WalletEvent::BlockProcessed / TransactionDetected.
• PlatformWallet::lock_outpoint, unlock_outpoint, locked_outpoints; lock and unlock persist before returning.
• On load, the collateral of every registration in a wallet's history is locked (a named collateral only from a record in a block).
• Tracked masternodes: a wallet locks a tracked masternode's collateral only when it holds the coin, either when the collateral becomes tracked (load, wallet registration, a refresh that learns the registration) or when a transaction check brings the coin in.
• PersistenceCapabilities::OUTPOINT_LOCKS (bit 16).

rs-platform-wallet-storage

• V021 adds core_locked_outpoints (wallet_id, outpoint), cascading with the wallet. A table of its own because a lock can exist before its coin and outlives the coin's spend.

rs-platform-wallet-ffi

• Persistence extension trio, appended and size-negotiated: on_persist_wallet_changeset_outpoint_locks_fn, on_load_wallet_locked_outpoints_fn, on_load_wallet_locked_outpoints_free_fn. OUTPOINT_LOCKS is attested only with all three wired and declared.
• platform_wallet_locked_outpoints / _free, platform_wallet_lock_outpoint, platform_wallet_unlock_outpoint.

Swift SDK

• PersistentLockedOutpoint in the live (unreleased) DashSchemaV5, purged with its wallet; the trio's callbacks; ManagedPlatformWallet.lockedOutpoints(), lockOutpoint(_:), unlockOutpoint(_:); Storage Explorer views.

Changes relative to #5113

• Locks are persisted from wallet events instead of a queue on PlatformWalletInfo.
• A tracked collateral is no longer locked in every wallet of the manager, only where the coin is.
• A refresh of a tracked masternode no longer locks again what the user unlocked by hand; the next load does.
• Migration V019 -> V021, capability bit 13 -> 16, Swift entity in schema V5.

Temporary pin: every rust-dashcore crate points at 2cdb0d6f, the tip of dashpay/rust-dashcore#1391. The pin moves to the merged dev revision once #1391 lands. Moving the pin also required serde_with 3.24 in Cargo.lock.

Kotlin (follow-up): the JNI bridge builds its extension with ..Default::default(), so it compiles unchanged and leaves the trio unwired: Android keeps locks for the session only and does not attest OUTPOINT_LOCKS.

Known limits

• A load locks again the collateral of every registration in a wallet's history and of every tracked masternode the wallet holds, including one unlocked in an earlier session (as Dash Core does on load).
• The collateral of a masternode the user stops tracking stays watched until the next load.
• Hosts without the new callbacks keep locks for the session only.

How Has This Been Tested?

Run locally before the final rebase onto v5.1-dev:

• cargo fmt --all --check
• cargo clippy with the wallet CI package list, --all-targets --all-features -- --no-deps -D warnings
• cargo test -p platform-wallet (1668 passed), -p platform-wallet-storage (436 + 565 passed), -p platform-wallet-ffi (522 passed)
• cargo check --workspace --all-targets
• bash packages/swift-sdk/run_tests.sh: swift test 1002 tests, 0 failures; SwiftExampleApp tests succeeded on an iPhone 17 simulator
• python3 scripts/check_sdk_parity_manifest.py, bash scripts/check-storage-explorer.sh, freeze_schema_models.py --check and --check-inventory

After the rebase (no conflicts): the wallet crates compile and the lock tests were run again.

New tests cover: sends, DashPay payments, asset locks and a ProUpServTx fee never spending the collateral; explicit lock and unlock; a registration block's lock reaching the changeset through a real process_block_for_wallets; a tracked collateral locked on arrival and not in a wallet that never holds it; an unlock by hand surviving a refresh; load-time locks being stored; SQLite round trips; the FFI trio and capability gating; the Swift handler, purge and C shims.

Not run: Kotlin instrumented tests (no Kotlin change).

Breaking Changes

Not consensus-breaking. API and storage changes:

• CoreChangeSet gains outpoint_locks; PlatformWalletInfo gains a crate-private field.
• PersistenceCallbacksExtension and PersistenceExtensionCallbacks gain three fields (additive, size-negotiated for C hosts).
• SQLite schema V021; Swift live schema V5 gains an entity.
• Through key-wallet: a coin a ProRegTx names as collateral is no longer spendable once the ProRegTx is in a block, until unlocked.

Walkthrough

The wallet now locks outpoints, including tracked masternode collateral, and persists lock state across reloads through Rust storage and SwiftData. The SDK exposes lock, unlock, and listing operations. The workspace also updates eight shared Rust dependency revisions.

Changes: Outpoint lock support

Layer / File(s)	Summary
Wallet lock state and collateral tracking packages/rs-platform-wallet/src/changeset/*, packages/rs-platform-wallet/src/wallet/outpoint_locks.rs, packages/rs-platform-wallet/src/manager/*, packages/rs-platform-wallet/src/masternode/tracked.rs, related wallet tests and fixtures	Core changesets carry lock and unlock deltas. Wallets lock registered or tracked collateral, update balance and spend state, and persist locks created during registration. Tests cover collateral tracking, coin selection, payment, and wallet lifecycle behavior.
Wallet loading packages/rs-platform-wallet/src/manager/load.rs, packages/rs-platform-wallet-storage/src/sqlite/rehydrate.rs	Wallet loading collects locks from replayed transactions and known masternodes. SQLite rehydration applies persisted locks and registration collateral locks.
SQLite storage and restoration packages/rs-platform-wallet-storage/migrations/*, packages/rs-platform-wallet-storage/src/sqlite/*, packages/rs-platform-wallet-storage/tests/integration/*	SQLite stores locks in core_locked_outpoints, restores locks before UTXOs, and derives each loaded UTXO’s lock state from the restored set. Integration tests cover reloads, later-arriving coins, unlocks, and wallet-scoped deletion.
Rust FFI lock operations and persistence packages/rs-platform-wallet-ffi/src/*	The FFI adds lock, unlock, and listing functions. The persistence extension adds lock-change, load, and free callbacks and negotiates the OUTPOINT_LOCKS capability.
Swift API and persistence integration packages/swift-sdk/Sources/SwiftDashSDK/*, packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/*, packages/swift-sdk/SwiftTests/SwiftDashSDKTests/*, packages/swift-sdk/schema-models.json	The Swift SDK adds outpoint lock operations and a SwiftData model. Its persistence handler stores, loads, and deletes lock rows. The example app lists and displays the records; tests cover persistence and FFI callbacks.
Shared dependency revision Cargo.toml	Eight shared rust-dash dependencies now pin revision 6b985d1f2a19b2a438392822b505627b989be27a instead of f6bb90cbbcae3d401bb3c9ebc4a9a26873a41404.

Merge Risk: Moderate · up to ddedc

Masternode collateral is now kept out of coin selection and the locks persist across restarts. Several narrow race windows remain: collateral can stay spendable until the next refresh or load, a queued lock can override an unlock after restart, and a payment prepared before a lock can still spend locked collateral. These cases are unlikely and recoverable, but they should be fixed or explicitly accepted before merge.

Explanation

The title "feat(platform-wallet): keep masternode collateral out of coin selection" matches the main change. The PR adds persistent outpoint locks so masternode collateral is excluded from coin selection. The changeset also covers locking, unlocking, persistence, and FFI/Swift APIs. The title names the primary behavior and the affected crate, which is concise and specific.

Final validation — Phase 1 + Phase 2

Static verification of head 14f1644 confirms seven blocking issues involving registration authentication, collateral recovery, wallet-generation ownership, initialization ordering, and persistence correctness. The remaining suggestions address untracking, defensive FFI restoration, and flush-error classification. Current CI reports Rust workspace and Kotlin checks passing, wallet-specific tests skipped, and Swift build/tests still running; no local builds or tests were run.

🔴 7 blocking | 🟡 3 suggestion(s)

🟡 Suggestion: Stop watching collateral when its masternode is untracked
packages/rs-platform-wallet/src/masternode/tracked.rs:764-766

untrack_blocking removes only the registry row. The new PlatformWalletInfo::tracked_collaterals sets have insertion paths but no removal path, so lock_arrived_tracked_collaterals continues locking the outpoint when its coin arrives later in the session. A restart clears that watch, making the result depend on whether the process has restarted since the user stopped tracking the node. This is introduced by the new tracking supplement even though it is documented as a known limit. Remove the collateral watch from the affected wallets when untracking succeeds, accounting for any remaining tracked registration that references the same collateral. Leave existing lock entries intact; stopping future automatic locking does not require automatically unlocking a currently protected coin.

In `packages/rs-platform-wallet/src/masternode/tracked.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/masternode/tracked.rs:845-852: Authenticate fetched registrations before using them to lock funds
  This path promotes cached registration details into authority over wallet spendability without binding them to the tracked proTxHash. In learn, Sdk::get_transaction accepts and decodes the server's transaction, and registration_from_transaction checks only that it is a ProRegTx. A malicious DAPI endpoint can return a fabricated registration naming an unrelated wallet UTXO as external collateral; this code then locks and persists that coin. The registration is fetched only once, and known_collaterals reapplies its collateral on later loads, so changing endpoints does not repair the poisoned cache. Verify the transaction ID against the requested proTxHash before caching or applying registration details, following operator_reward_from_registration. Existing cached details also need verified registration evidence before authorizing locks. Add a mismatched-response regression test proving that neither the registration nor its collateral lock is accepted.
- [SUGGESTION] packages/rs-platform-wallet/src/masternode/tracked.rs:764-766: Stop watching collateral when its masternode is untracked

- [BLOCKING] packages/rs-platform-wallet/src/wallet/outpoint_locks.rs:268-275: Reuse key-wallet's retained-coin ownership rule
  Checking only utxos excludes owned coins that key-wallet retains under reversible spends. Receive collateral, process its spend in a non-chainlocked block, then track a registration that this wallet never processed: track_collaterals remembers the outpoint but does not lock it. When truncate_above removes the spend, upstream restores the coin directly without rechecking its funding transaction, so the arrival hook does not run. Later refreshes also skip the already-tracked outpoint, leaving the collateral selectable. The pinned upstream holds_coin deliberately includes spent_before_funded, claim_guarded_outputs, and unsettled_spends. Expose and reuse that canonical query rather than reconstructing its lifecycle state here. The same upstream-helper reuse gap affects registration_collateral, which currently copies masternode_collateral exactly; expose that extraction helper too to keep load-time and transaction-check rules aligned. Cover tracking while spent followed by truncation and coin selection.
- [BLOCKING] packages/rs-platform-wallet/src/wallet/outpoint_locks.rs:370-377: Fence lock access to the handle's wallet generation
  This lookup checks only wallet_id. Retain a PlatformWallet handle, remove the wallet, and recreate it from the same seed: the ID is unchanged, but the generation is new. Calling unlock_outpoint through the retained handle now unlocks and persists the replacement wallet's collateral. The manager write guard prevents replacement during this operation but does not establish the handle's authority over the current generation. This also reaches direct Rust callers and retained FFI handles. Compare info.generation with self.generation using Arc::ptr_eq under the guard before mutating or storing, as transaction finalization already does, and apply the same ownership check to locked_outpoints. Add a remove/recreate test proving that the predecessor handle cannot read or modify the successor's locks.
- [SUGGESTION] packages/rs-platform-wallet/src/wallet/outpoint_locks.rs:395-397: Preserve flush-error classification for explicit lock operations
  Store failures preserve the persister's structured classification, but this flush failure is reduced to a Persistence string. A transient flush failure therefore loses the distinction callers need to retry flush rather than treat the operation as fatal. PlatformWalletError::from_flush_failure exists specifically to preserve the backend classification for this operation and is already used by sibling persistence paths. Use it here as well.

In `packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletPersistenceHandler.swift`:
- [BLOCKING] packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletPersistenceHandler.swift:5461-5468: Do not acknowledge lock writes when the network is unknown
  This branch discards every lock delta while allowing the persistence round to report success. The state is supported: the public persistence-handler initializer and advanced manager configuration default to no network, and a PersistentWallet can also have an unresolved network. The added no-network test explicitly confirms successful completion without a stored row. Nevertheless, the handler advertises OUTPOINT_LOCKS unconditionally, so an explicit Rust lock_outpoint call can report durable success for a manually locked outpoint that becomes spendable after restart. Registration replay cannot reconstruct an arbitrary hand lock. Supply the authoritative network to storage, preserve the unresolved write losslessly, or fail the round until it can be stored. The host must not silently choose session-only persistence while attesting durable lock support.

In `packages/rs-platform-wallet-storage/src/sqlite/rehydrate.rs`:
- [BLOCKING] packages/rs-platform-wallet-storage/src/sqlite/rehydrate.rs:308-317: Preserve registration evidence for SQLite upgrade recovery
  V021 creates an empty lock table for existing databases, so upgrade safety depends on the new history-derived recovery pass. However, load_state decodes persisted registrations into core.records, while apply_persisted_core_state drops those records and load_one_wallet returns a history-free ManagedWalletInfo. Consequently, lock_registered_collaterals finds nothing: a database containing a confirmed ProRegTx and its unspent collateral, without an independently tracked masternode, loads the collateral unlocked. Restoring the existing scan cursor does not guarantee that registration will be checked again. The history omission predates this PR, but the new recovery mechanism now depends on that evidence. Preserve the required registration records through the startup-state contract and apply the shared Rust collateral rule before publication. TransactionRecord already contains the raw transaction, contrary to the nearby omission comment.

In `packages/rs-platform-wallet/src/manager/load.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/manager/load.rs:745-749: Establish collateral locks before publishing restored wallets
  This recovery pass runs after each restored wallet has entered both the shared WalletManager and self.wallets. When no persisted lock row exists, known tracked or history-derived collateral remains spendable between publication and this pass. get_wallet_blocking reads the published map without waiting for load completion, so another task can obtain the first wallet and finalize a collateral-spending transaction while hydration of a later wallet is suspended. The generation check in transaction finalization passes because this is the current generation. Locking afterward cannot undo the signed transaction. Apply known-collateral locks and initialize tracking on each PlatformWalletInfo before inserting it into the shared manager, as registration already does. Persistence of the resulting lock deltas can remain deferred until the batch passes its rollback point.

In `packages/rs-platform-wallet/src/changeset/core_bridge.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/changeset/core_bridge.rs:1634-1640: Order automatic lock persistence with explicit mutations
  An event's historical locked_outpoints are always converted into true writes, independently of explicit unlock persistence. A transaction check can queue a lock event, unlock_outpoint can subsequently persist false and return successfully, and the older event can then commit true. The manager guard held by the explicit mutation does not serialize against the adapter's later commit. This is observable beyond intentional registration relocking on load: for collateral known only through tracking, untrack the masternode and explicitly unlock before the queued arrival event commits; the stale true row then restores a lock after restart despite no remaining registration evidence. Centralize ordering across explicit mutations, event commits, and the snapshot-then-store persist_outpoint_locks path using a shared ordered commit mechanism or revisions enforced through commit. Filtering only at event projection time would leave another snapshot-to-commit race.

In `packages/rs-platform-wallet-ffi/src/persistence.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/persistence.rs:1969-1976: Validate the lock loader's pointer and count before allocation
  A successful host callback with a null outpoints_ptr and positive count is interpreted as an empty lock set and returns Ok. That silently restores protected coins as spendable instead of rejecting inconsistent host output. Vec::with_capacity(count) also runs before this condition is checked, so a malformed large count can trigger an allocation failure before validation. The wallet-list loader in this file already rejects a positive count without a buffer. Apply equivalent fail-closed validation here before allocation, validate the representable slice byte length, and ensure the host free callback runs on validation-error paths where a buffer was returned. Add a callback test returning null with count 1. The supplied Swift shim is consistent, so this is defensive integration validation rather than a demonstrated Swift failure.

🔴 Blocking: Reuse key-wallet's retained-coin ownership rule

Checking only utxos excludes owned coins that key-wallet retains under reversible spends. Receive collateral, process its spend in a non-chainlocked block, then track a registration that this wallet never processed: track_collaterals remembers the outpoint but does not lock it. When truncate_above removes the spend, upstream restores the coin directly without rechecking its funding transaction, so the arrival hook does not run.

[llbartekll]

Declining for this PR: holds_coin and masternode_collateral are pub(crate) in key-wallet at the pinned revision, so reusing them needs an API change in rust-dashcore#1391. The case is a reorg that undoes a collateral spend made before the masternode was tracked; the next load locks the coin.

[thepastaclaw]

Still applies (re-reviewed at ef24d317): The helpers are private at both inspected upstream revisions, confirming the API change you identified is necessary. However, truncation restores retained coins without running the funding-arrival hook, so the next-load repair leaves an interval in which an ordinary send can spend the restored collateral.

[llbartekll]

Deferring to #5913. rust-dashcore#1400 made both helpers public, but the pin cannot move past rust-dashcore#1379 without a change in dpp, so the copies stay in this PR and #5913 tracks moving the pin and dropping them.

[llbartekll]

Declining: this is the race the module docs already describe. It fails toward the coin staying locked, and the user can unlock again. A shared ordered-commit mechanism is beyond this PR's scope.

[thepastaclaw]

Still applies (re-reviewed at ef24d317): The manager remains unlocked while only persistence is relocked, so locked_outpoints() gives the caller no indication that the acknowledged unlock must be repeated. This is durable/live-state divergence introduced by the new lock writers, not merely conservative coin selection; documenting it does not order the writes through commit.

[llbartekll]

Deferring this one: please file a tracking issue. Ordering explicit lock changes with the event adapter's writes needs a commit path shared by both, which is a change of its own.

Re-review — Final validation — Phase 1 + Phase 2

Updated after discussion: 1 finding(s) of this review were settled in the inline threads; 5 blocking finding(s) still stand.

• ✅ Withdrawn: 🟡 Stop watching collateral when its masternode is untracked

This revision fixes wallet-generation isolation, flush-error classification, malformed lock-loader responses, SQLite registration recovery, and Swift writes with an unknown network. Registry propagation and upgrade-time cache/read handling still need changes. Static review only: current Rust workspace, Swift, Kotlin, schema, and explorer checks pass; review/hygiene checks remain pending, and the two newer base commits introduce no conflicting files.

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

🔴 Blocking: Propagate tracked-registry load failures before enabling spending

This protection pass now depends on successful tracked-registry hydration, but load_tracked_masternodes_from_persistence still delegates to a loader that logs errors and continues with an empty registry. The earlier wallet snapshot load does not load this registry. During an upgrade, a wallet can therefore restore its collateral successfully while the separately persisted registration fails to load and no dedicated lock row exists yet. known_collaterals() then treats the unreadable registry as empty and the wallet is published with its collateral selectable. Although the swallowing loader predates this PR, making its result an input to spending protection introduces this fail-open consequence. Propagate a typed registry-load failure before publication, or hold spending until hydration succeeds, and cover a successful wallet load followed by a failed registry read.

_{source: gpt-6.1-sol (phase2-reviewer: rust-quality)}

[llbartekll]

Declining: the registry's fail-soft load predates this PR and is deliberate, so an unreadable registry does not make the wallets unloadable. A collateral locked once has its own stored lock row, so this matters only before that first lock.

[thepastaclaw]

The deliberate fail-soft behavior is exactly what makes this new protection path fail open. On the current load path, load_from_persistence logs the error and leaves the registry empty, after which known_collaterals() returns no tracked collateral before the wallet is published. The persisted lock-row case is safe, but it is not guaranteed for wallets upgraded from older state, hosts without durable lock callbacks, or a first load before the automatic lock has ever been recorded; those are the cases this PR newly claims to protect.

[llbartekll]

Deferring this one: please file a tracking issue. Whether an unreadable tracked-masternode registry should fail the wallet load is a decision for the registry's owners and changes behaviour that predates this PR.

🟡 Suggestion: Stop watching collateral when its masternode is untracked

[llbartekll]

Declining: an untrack during the refresh's network fetch already ends the refresh with "not tracked" before this step. The remaining window is between that return and taking the manager lock, and the outcome is a visible lock the user can remove.

[thepastaclaw]

I agree this does not warrant keeping the finding. The refresh gate correctly prevents an untrack during the network fetch from being resurrected by the registry write, and the remaining post-return lock is an explicitly visible, user-removable lock consistent with the documented behavior that an existing collateral lock can remain after untracking.

Withdrawing this finding.

- Around line 324-325: Update the rehydration flow around
`registered_collaterals` and `wallet_info.lock_outpoint` to reapply persisted
explicit unlocks after registration-derived locks, using the existing
persisted-state mechanism. Add a reload test that unlocks a registered
collateral, restarts the wallet, and verifies it remains spendable.

Review comments at @packages/rs-platform-wallet/src/manager/load.rs:
- Around line 318-319: The load_locks_by_wallet insertion can persist locks from
a snapshot that was never installed, overriding a live wallet unlock. Collect
lock deltas only after successful snapshot installation, discard them when the
existing-wallet check or re-read path rejects the snapshot, and bind deferred
writes to the installed generation so they cannot overtake subsequent unlocks.

Review comments at @packages/rs-platform-wallet/src/manager/wallet_lifecycle.rs:
- Around line 374-376: Update the wallet registration flow around lock
initialization and insert_wallet to re-read known_collaterals() after the wallet

persist the returned locks with persist_outpoint_locks, matching refresh.
Preserve the existing pre-publication registration behavior.

Review comments at @packages/rs-platform-wallet/src/masternode/tracked.rs:
- Around line 859-863: Serialize the wallet tracking update in
`refresh_row_and_persist` with registry removal in `untrack_blocking` using a
shared synchronization boundary that remains effective across the awaited
`track_masternode_collaterals` call. Ensure removal cannot complete before a
pending refresh reconciles tracking, or a refresh can reinsert tracking after
removal; a registry check before the await alone is insufficient.

Review comments at @packages/rs-platform-wallet/src/wallet/outpoint_locks.rs:
- Around line 381-383: Serialize the explicit unlock changeset with the
adapter’s persistence stream instead of writing it directly through
persister.store(changeset). Ensure queued automatic lock events are persisted
first and the explicit unlock remains the latest durable operation, including
after restart; do not rely on the wallet-manager write lock to order queued
writes.
- Around line 364-367: Ensure inputs locked after payment preparation cannot be
broadcast: either check each prepared input’s lock state in
send_prepared_payment and broadcast_finalized_transaction under the
wallet-manager lock, or update set_outpoint_lock to release reservations for an
outpoint when locking it so later sends fail with StaleReservation. Add a test
that prepares a payment, locks one of its inputs, and verifies the send is

Re-read tracked collaterals after the wallet is published.

The registration samples known_collaterals() at wallet_lifecycle.rs:374-376. It awaits at lines 388, 433, and 546-550 before insert_wallet publishes the wallet.

A tracked-masternode refresh can learn a collateral in that window. Its track_masternode_collaterals call (masternode/tracked.rs:859-863) reaches only wallets already in the manager, so it skips this wallet. The wallet then publishes with a tracked_collaterals set that lacks the collateral. Arrival handling locks only coins in that set. The collateral can stay spendable until a later refresh or reload.

After publication, read known_collaterals() again and call track_masternode_collaterals. Persist the returned locks with persist_outpoint_locks, as refresh does. A refresh that updates the registry after the re-read runs its track call after publication, so it reaches this wallet.

Serialize wallet tracking with registry removal.

refresh_row_and_persist releases its gate before this awaited wallet update. A refresh can commit its snapshot, then pause here. untrack_blocking can remove the registry row, remove the wallet's tracking entry, and return success. When the refresh resumes, it inserts the tracking entry again from its retained snapshot.

If the collateral arrives later, the wallet locks and persists it even though the masternode is no longer tracked. Serialize registry removal and wallet tracking reconciliation. A registry check before this await alone does not close the race.

Reject locked inputs before a prepared transaction is broadcast.

A prepared transaction keeps its inputs reserved after signing. send_prepared_payment and broadcast_finalized_transaction check only the reservation age before they call the broadcaster. Neither path checks the outpoint lock. If lock_outpoint runs after a transaction is prepared, the later send still broadcasts the locked collateral input.

Choose one fix and cover it with a test that prepares a payment, locks one of its inputs, and then sends:

• Check the outpoint lock state in the send paths before broadcast, under the wallet-manager lock.
• Or release the affected reservations in set_outpoint_lock when an outpoint is locked, so the later send fails with StaleReservation.

Order explicit unlocks after earlier automatic lock events.

If a registration's lock event is still queued, this direct store writes false first. The adapter then stores the older event's true. The outpoint remains unlocked in memory but becomes locked after restart, despite the successful unlock.

The module documents this sequence at Line 25–27. Holding the wallet-manager write lock does not order writes from events already queued. Serialize explicit changes with the adapter's persistence stream so the latest operation remains the durable state.
