feat(platform-wallet): persist the Orchard recipient of a shielded asset-lock funding - #5762
A Core → Shielded funding (Type 18 ShieldFromAssetLock) is two steps: the asset lock is broadcast first, the shield transition is submitted after the lock is proven. If the host app is killed in between, the transfer is resumed later from the tracked lock, but TrackedAssetLock / AssetLockEntry carried no recipient, so both the generic shielded_resume_fund_from_asset_lock and a repeated-UUID shielded_fund_from_wallet_drain built the transition with whatever recipient the resuming call passed. dashwallet-ios works around this with an app-side marker for the wallet drain only (dashpay/dashwallet-ios#1251); typed-amount sends are uncovered (dashpay/dashwallet-ios#1253) and a Kotlin host would need the same machinery again.
What was done?
Rust (platform-wallet)
TrackedAssetLock and AssetLockEntry gain one optional field, shielded_recipient: Option<ShieldedRecipientRaw> — the raw 43 bytes of the Orchard address, because these types, the SQLite persister and the FFI persistence layer are built without the shielded feature where dpp::address_funds::OrchardAddress does not exist; only shielded code converts, and the resume check compares bytes (a corrupted recorded recipient matches nothing and is refused, not paid). (Address only; the pre-flight already refuses explicit per-recipient credits, so there is nothing else to record). It is set at the single row-creation site (build.rs::broadcast_funded_asset_lock_tracked, the former body of broadcast_funded_asset_lock_with_operation), and it is durable before dispatch: the row is stored and flushed before the lock is tracked or broadcast, for a drain and, on a backend that attests ASSET_LOCK_SHIELDED_RECIPIENTS, for a typed-amount funding too. A failed store or flush there aborts before the broadcaster, releases the reservation and returns a Persistence error (a behaviour change: such a funding used to proceed with only a logged store error). A host without the capability keeps the queued best-effort row. The recipient is threaded as a parameter from resolve_funding_with_is_timeout_fallback; identity and Type 14 callers pass None.
On resume (FromExistingAssetLock, which by then also covers a Pending repeated-UUID drain) the check runs right after recipient validation and before any funding resolution: the build pays the recorded recipient; a different one is refused with the new typed AssetLockRecipientMismatch (nothing reserved, waited for or sent; a drain's operation stays Pending with its outpoint). Rows tracked before the recipient was recorded carry none and keep accepting the caller's. The caller-supplied recipient stays required and checked on both entry points, so no FFI/Swift/Kotlin signature changes.
The recipient is immutable once recorded, with the same rule as the UUID: preserve_recovery_metadata (changeset merge and apply.rs) keeps it when a later snapshot lacks it and drops a snapshot naming another one. Without this a reconstruction/chainlock-promotion snapshot would erase it and silently fall back to the legacy semantics.
New capability bit ASSET_LOCK_SHIELDED_RECIPIENTS (1 << 14), attested by the SQLite persister and the Swift handler (both implement it). Reported, not added to WALLET_DRAIN: an un-updated host keeps draining and simply gets the pre-recipient resume behaviour.
SQLite (platform-wallet-storage): migration V020__asset_lock_shielded_recipient.rs adds a nullable 43-byte shielded_recipient column (CHECK + immutability trigger, as V019 did for the UUID); the frozen lifecycle blob is untouched. The upsert COALESCEs and rejects a conflicting value before any write; the readers check the length (whether the bytes are a payable address is the wallet's call, at resume). SCHEMA.md row added; the migration fingerprints in sqlite_schema_pinning.rs repinned for the added file.
FFI (platform-wallet-ffi): AssetLockEntryFFI is frozen, so the recipient rides two size-negotiated slots appended to PersistenceCallbacksExtension (on_persist_asset_lock_shielded_recipient_fn, on_load_asset_lock_shielded_recipient_fn; extension version unchanged). A host without the slots is not failed on store (unlike the UUID, every Type 18 funding now carries a recipient) and loads rows with none. FFI error code 61 ErrorAssetLockRecipientMismatch (registry row added), mapped in error.rs and in the map_asset_lock_funding_result allow-list so it does not flatten to ErrorWalletOperation. TrackedAssetLockFFI gains has_shielded_recipient + shielded_recipient_raw_43 (read-only exposure; the struct has no layout freeze and is consumed only by the Swift SDK built from the same tree).
Swift: PersistentAssetLock.shieldedRecipientRaw43: Data? on the live model, keep-on-nil in persistAssetLocks, persistAssetLockShieldedRecipient / loadAssetLockShieldedRecipient + C trampolines + extension wiring, AssetLockEntrySnapshot.shieldedRecipientRaw43, TrackedAssetLock.shieldedRecipientRaw43, and the three error-mirror edits for code 61.
Kotlin: DashSdkError.PlatformWallet.AssetLockRecipientMismatch and the 61 -> arm only. Kotlin has no asset-lock sidecar at all today (no operationId either), so its Room column and the two JNI extension slots are a follow-up together with the UUID sidecar. Until then an Android host does not attest the bit, loads rows with no recipient and resumes with the caller's address, exactly the pre-PR behaviour; there is no tracking issue for the Android sidecar yet.
Swift schema versioning. Schema 4.0.0 was published and frozen while this PR was open (#5785), so the attribute moved to a new version: DashSchemaV4.models is bound to DashSchemaSnapshotV4.models, DashSchemaV5 (5.0.0) carries the live models, and both migration plans gain a lightweight V4→V5 stage (the attribute is optional, so no custom stage). Store-open route labels became published-v4-to-v5 / labelled-current-v5, and the tests pinning the current version follow. No DashSchemaSnapshotV5 is added; that is generated by the release freeze.
Not in scope: #5607 (cap on the drained balance) stays a separate PR; #5580 (proof-backed "already consumed") is in #5581.
How Has This Been Tested?
All with --all-features --locked:
cargo check --all-targets and cargo clippy ... -- --no-deps -D warnings (the CI set: platform-wallet, platform-wallet-storage, platform-wallet-ffi, rs-unified-sdk-ffi, rs-unified-sdk-jni) clean; cargo fmt --all.
platform-wallet: new tests — generic resume to another recipient refused (no send, no staged write, row unchanged); repeated-UUID drain to another recipient refused with the operation left Pending with its outpoint; legacy row without a recipient accepts the caller's; the recipient is on the committed row before the broadcast for both the drain and the typed-amount path (the latter on a buffered backend); a rejected store and a rejected flush abort a typed-amount funding before the broadcast and release its inputs; a backend without the capability keeps the best-effort dispatch; resume_recipient unit cases; merge/apply keep the recipient over a stale snapshot and drop a conflicting one; serde adapter round-trip and rejection. The full crate suite passes.
platform-wallet-storage: full suite passes; new tests for keep-when-later-snapshot-lacks-it / reject-a-change / column CHECK and trigger, and a stored value of the wrong length failing the load.
Default-feature builds (cargo check -p platform-wallet-storage -p platform-wallet-ffi -p rs-unified-sdk-jni --locked, no shielded) compile; cargo check -p platform-wallet alone fails on the pre-existing dpp::ed25519_dalek import in masternode/locator.rs, untouched here.
platform-wallet-ffi: sidecar round-trip incl. a host without the slots, capability attestation needing both slots, code 61 pin, allow-list, extension layout pin.
python3 scripts/check_sdk_parity_manifest.py OK.
Not run locally: the Swift V5 schema change (only syntax-checked; no xcframework on this machine, CI is the verification), Swift package tests (one new AssetLockOperationPersistenceTests case, capability declaration test updated), Kotlin Gradle tests (one new DashSdkErrorTest case), the iOS build. The C header is generated by cbindgen at build time, so the new constant and struct fields appear automatically.
Breaking Changes
None for hosts: FFI entry-point signatures are unchanged, AssetLockEntryFFI is unchanged, the extension struct grows only through size negotiation. TrackedAssetLockFFI gains two trailing fields (hosts rebuild against the generated header). Rust: resolve_funding_with_is_timeout_fallback and the create_funded_asset_lock_proof_*_observed / create_wallet_drain_asset_lock_proof helpers take the new parameter (crate-internal callers updated).

Summary by CodeRabbit
New Features
Shielded asset-lock resumes retain the original recipient across storage and restore, including when older snapshots omit recipient details.
Requests to resume a lock with a different recipient are rejected before funding or payment. Older locks without a recorded recipient can still use the recipient supplied with the request.
Recipient-mismatch errors are now available as typed errors in the Kotlin and Swift SDKs, with details identifying the mismatch.
…set-lock funding
A Core -> Shielded funding (Type 18) broadcasts an asset lock first and
submits the shield transition after the lock is proven. If the host is
killed in between, the transfer is resumed from the tracked lock, but the
row carried no recipient, so both the generic resume and a repeated-UUID
wallet drain paid whatever recipient the resuming call named.
Record the recipient on `TrackedAssetLock` / `AssetLockEntry`
(`shielded_recipient: Option<OrchardAddress>`, address only) at the one
row-creation site, so it is exactly as durable before dispatch as
`operation_id`. On resume, pay the recorded recipient and refuse a
different one with the new typed `AssetLockRecipientMismatch` (FFI code
61), before any funding resolution. Rows tracked before the recipient was
recorded carry none and keep accepting the caller's. The recipient is
immutable once recorded: merge, apply, the SQLite upsert and the Swift
persister all keep it when a later snapshot lacks it and reject a change.
Persistence: serde adapter on the changeset; SQLite migration V020 adds a
nullable 43-byte column with an immutability trigger (lifecycle blob
untouched); two size-negotiated FFI extension slots carry it as a sidecar
next to the frozen `AssetLockEntryFFI` row, attested by the new
`ASSET_LOCK_SHIELDED_RECIPIENTS` capability (reported, not required by
`WALLET_DRAIN`; a host without the slots still stores the row). Swift adds
`PersistentAssetLock.shieldedRecipientRaw43` to the live V4 model (not yet
frozen: schema-releases.json registers 3.0.0 only) with the sidecar
callbacks; `TrackedAssetLockFFI` and the Swift `TrackedAssetLock` expose
the recipient read-only. Kotlin maps code 61; its sidecar follows with the
UUID sidecar it also lacks.
Closes#5603.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
Shielded asset locks now record an optional 43-byte Orchard recipient. Storage and restore paths preserve it, and resume rejects a different requested recipient when one is recorded. The FFI and Swift and Kotlin SDKs expose persistence support and a typed mismatch error with code 61.

Summary
Recipient state and recovery metadata packages/rs-platform-wallet/src/changeset/*, packages/rs-platform-wallet/src/wallet/apply.rs, packages/rs-platform-wallet/src/wallet/asset_lock/tracked.rs
AssetLockEntry and TrackedAssetLock carry an optional 43-byte recipient. Changeset merging and replay preserve recorded recipients and reject conflicting recipient metadata.
Funding and resume validation packages/rs-platform-wallet/src/wallet/asset_lock/*, packages/rs-platform-wallet/src/wallet/shielded/*, packages/rs-platform-wallet/src/wallet/identity/network/registration.rs, packages/rs-platform-wallet/src/wallet/platform_addresses/fund_from_asset_lock.rs
Funding passes the recipient into tracked-lock creation. When the backend advertises recipient persistence, recipient-bearing locks are stored and flushed before tracking or broadcast. Resume accepts matching recipients and legacy locks without a recorded recipient, and rejects a mismatch.
SQLite stores the recipient in a nullable sidecar column. Writes retain it when snapshots omit it and reject conflicting or malformed values. Loads restore it. Tests cover persistence, validation, migration fingerprints, capability reporting, and existing entry fixtures.
FFI and Swift persistence packages/rs-platform-wallet-ffi/src/*, packages/swift-sdk/Sources/SwiftDashSDK/Persistence/*, packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/*, packages/swift-sdk/SwiftTests/SwiftDashSDKTests/*
The FFI adds negotiated recipient callbacks and a persistence capability bit. Swift adds recipient fields, callback handling, and persistence tests.

Possibly related issues
dashpay/platform#5778: The issue describes sweep and reinstatement paths that can remove recorded recipient data and allow resume with another address. This relates to recipient preservation and resume validation covered here.
dashpay/platform#5713: This issue concerns compatibility risks in the unversioned AssetLockEntryWire format. This change stores the recipient outside the lifecycle blob and leaves that blob unchanged.
Possibly related PRs
dashpay/platform#5288: Both PRs use SQLite migration version V020 for different schema changes.
The change records the shielded recipient on asset locks and rejects a resume to a different recipient. On capable backends it stores and flushes the recipient before dispatch. No remaining merge-blocking risk was found.

Explanation
[#5603] The wallet records the recipient, checks it on resume, returns a typed mismatch error, and exposes it through FFI and Swift. Tests cover these paths and legacy rows. SQLite and Swift persist the recipient. Explicit per-recipient credits are rejected by preflight.
The durability requirement is not met for hosts without ASSET_LOCK_SHIELDED_RECIPIENTS. build.rs allows new funding to proceed with best-effort persistence. The FFI host can store a new row without the recipient, and resume_recipient then accepts any caller-supplied address. This includes the current Kotlin host. The issue permits that behavior only for legacy rows, not new funding. The prior assessment's claimed exception for non-capable hosts is not in the issue.
Resolution
Ensure new shielded funding cannot dispatch without durable recipient storage. Preserve caller-supplied recipients for legacy rows. Add tests for non-capable hosts and recovery after restart.

Final validation — Phase 1 + Phase 2
The recipient check belongs in platform-wallet, but recovery remains vulnerable to recipient loss before non-drain dispatch and across sweep/reinstatement. The change also breaks non-shielded builds and changes a published C array layout without negotiation; capability reporting and the Android follow-up are incomplete. This was a static review: current Rust, Swift, Kotlin and frozen-schema checks pass, PR Hygiene remains pending, and the supplied base-drift evidence reports no conflicts.

🔴 Blocking: Make the recipient durable before non-drain dispatch packages/rs-platform-wallet/src/wallet/asset_lock/build.rs:1468-1481
Fixed-amount funding and DrainAccountBalance have no operation context, so they enter this branch instead of the store-and-flush checkpoint above. queue_asset_lock_changeset logs and ignores store failures and never flushes. PlatformWalletPersistence explicitly permits buffering until flush, and SQLite implements that behavior in FlushMode::Manual. Consequently, even a recipient-preserving backend can broadcast the Core transaction without durably recording its destination. After termination, reconstruction creates the lock with shielded_recipient: None, and resume_recipient accepts another caller-provided address as though this newly created lock were legacy. Require a successful durable checkpoint for recipient-bearing funding before making the row resumable or broadcasting, independently of the drain UUID, and handle checkpoint failures with appropriate pre-send cleanup. Add failed-store and buffered-store interruption coverage. The new ordering test inspects persistence only after the call returns and accepts staged state, so it does not prove durability or ordering at broadcaster entry.

- [BLOCKING] packages/rs-platform-wallet/src/changeset/changeset.rs:1534-1541: Preserve compilation without the shielded feature
This feature-independent changeset now unconditionally requires OrchardAddress, which DPP exports only under shielded-client. platform-wallet defaults to bls and eddsa; its optional shielded feature enables dpp/shielded-client. The unconditional imports and signatures in tracked.rs, build.rs, orchestration.rs and error.rs therefore break isolated default-feature and no-default-feature wallet builds. SQLite's new unconditional Orchard imports extend the problem to default storage builds. There is a separate test manifestation of the same boundary error: unconditional merge/apply tests call orchard_address_fixture, which is shielded-gated, and the storage test helper imports the shielded-gated dash_sdk::grovedb_commitment_tree re-export. Keep recovery metadata losslessly representable without shielded client tooling, converting to OrchardAddress inside shielded-enabled code, and align the fixtures and tests with that boundary. Workspace/all-features checks do not establish that these supported feature-off configurations compile.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/asset_lock/sync/reconstruction.rs:232-235: Retain the recipient across sweep and reinstatement
A reconstructed row is not necessarily a legacy lock. TransactionsSwept calls remove_tracked_asset_locks_for_swept, which deletes the complete live entry and emits a persistence removal, including any newly recorded recipient A. The supported chainlocked-return path then reaches this constructor and recreates the original outpoint with no recipient. apply_record inserts it directly into the live map, so neither preserve_recovery_metadata nor apply_changeset can restore A. A generic shielded resume subsequently accepts recipient B. This also affects a sweep and reinstatement folded into one persistence batch: SQLite may preserve A with COALESCE, but tracked_shielded_recipient reads the live row containing None. Preserve non-actionable recipient recovery metadata across removal and reattach it when the original outpoint is authenticated again. Extend the existing sweep/reinstatement test with a recipient-bearing, non-UUID lock; the related UUID conflict-history work in #5528 does not cover this new typed-amount invariant.

- [BLOCKING] packages/rs-platform-wallet-ffi/src/asset_lock/manager.rs:33-40: Preserve the published tracked-lock array ABI
These fields change TrackedAssetLockFFI's element size from 64 to 112 bytes on the supported 64-bit targets, while asset_lock_manager_list_tracked_locks retains its existing symbol and has no size/version negotiation. The previous layout is present in published revision a35c4ce8c75a0ac4e745766e469649ceba360b09, recorded in schema-releases.json, and the crate documents dynamic-library consumption. An existing consumer linked to the updated library reads locks[1] at offset 64, inside the first record's recipient bytes, and misdecodes subsequent outpoints, amounts and statuses. Rebuilding the in-tree Swift consumer fixes that pairing, not the exported binary interface. Preserve the existing struct and list/free API and expose the recipient through an additive getter or a versioned list API with a new element type. Add a multiple-record compatibility test using the legacy layout.

- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletPersistenceHandler.swift:3352-3355: Advertise recipient persistence from the implementing backends
Installing both callbacks does not advertise ASSET_LOCK_SHIELDED_RECIPIENTS. FFIPersister returns the intersection of callback support and the host's declared capabilities, but makePersistenceCapabilities still stops at assetLockOperationIds, and the Swift capability mirror has no bit-14 constant. SqlitePersister::persistence_capabilities likewise omits the new bit despite implementing its column and readers. Callers therefore cannot distinguish these updated backends from legacy implementations that discard the recipient. Add the Swift constant and declaration and SQLite's capability attestation, with tests against the actual backend capability results. WALLET_DRAIN can remain unchanged.
In `packages/rs-platform-wallet-ffi/src/persistence.rs`:
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/persistence.rs:2793-2800: Track the missing Android recipient-persistence path
This fallback applies to the current Android SDK, not only older hosts: rs-unified-sdk-jni's extension_for leaves both recipient slots unset, and Kotlin's AssetLockEntity has no Orchard-recipient column. A fresh Android funding therefore still loses its recorded destination on restart and resumes with the caller's address. This is a missed sibling of #5603 rather than a regression in Android, so a separate implementation is a reasonable deferral, but the description links no tracking issue covering this recipient metadata. Wire the JNI/Room path here or link a dedicated follow-up before deferring it; the existing absence of a UUID sidecar does not itself track recipient recovery.
Your move: thepastaclaw requested changes on this head; dismiss the review or push a fix; thepastaclaw left review threads unresolved; resolve them.
Full checklist in the description.
… capability
The changeset, the tracked locks, the SQLite persister and the FFI
persistence layer are built without the `shielded` feature, where
`dpp::address_funds::OrchardAddress` does not exist, so the recipient
recorded with a tracked asset lock is now carried as its raw 43 bytes
(`ShieldedRecipientRaw`). Only shielded code converts: the resume check
compares bytes, so a corrupted recorded recipient matches nothing and the
resume is refused rather than paid. Storage and FFI loaders check the
length only; the feature-independent tests use byte fixtures.
The SQLite persister and the Swift handler now report
`ASSET_LOCK_SHIELDED_RECIPIENTS`, which both already implement.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
On the non-inline finding ("make the recipient durable before non-drain dispatch", build.rs:1468-1481): not in this PR. The typed-amount and DrainAccountBalance paths queue the whole tracked row before broadcast without a flush; that is the lock's existing durability model, and the recipient rides the same row, so it is exactly as durable as the lock itself (and as the UUID). Requiring a flushed checkpoint before every non-drain broadcast changes the funding lifecycle for all asset-lock callers and belongs in its own change, if wanted.
Assert the expected error for the legacy-row resume.
The assertion passes for any error other than AssetLockRecipientMismatch. A refusal after the recipient check also passes. For example, the FromExistingAssetLock arm returns AssetLockNotTracked when the tracked-lock lookup misses (orchestration.rs:631). A change that refuses legacy rows at that point would not fail this test. Assert the specific error that this fixture produces after recipient resolution, so an earlier refusal fails the test.

Check the stored recipient while the broadcast call is in progress.
The test reads the stored row only after shielded_fund_from_asset_lock returns. A store that runs after the broadcaster.broadcast call still completes before that return, because the fixture commits inline. The test therefore does not detect that reordering.
A check that reads the row during the broadcast call would detect the reordering. That check must read the persistence state that exists at that point. On the typed-amount branch, the row is queued without a flush.

Add a test that exercises the registered recipient callback slots.
No Swift test reads the on_persist_asset_lock_shielded_recipient_fn or on_load_asset_lock_shielded_recipient_fn slots that makePersistenceCallbacksExtension() assigns. The recipient tests call the handler methods directly. The capability test compares capabilities.bits with a hard-coded mask. Neither check fails if one of the two assignments is removed. The slot then stays nil, and the suite does not report it.
Add a test that builds the callbacks from makePersistenceCallbacksExtension(), calls the registered persist and load slots with a 43-byte recipient, reloads the recipient, and asserts that the returned bytes match.

Row 61 claims `ErrorAssetLockRecipientMismatch`; the frontier note now
says so and names 62 as the next allocatable integer. The legacy-row
resume test asserts the funding-resolution error it reaches, so a
refusal before the recipient check would fail it.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
On the CodeRabbit nitpicks: the legacy-row resume test now asserts the specific post-check error (a5dd3e8). Note the fixture reaches AssetLockTransaction (lock address not in the funding account), not AssetLockNotTracked; the lock is tracked. The in-broadcast persistence probe and the Swift test that drives the C trampolines directly are not taken: both are new test harness for behaviour the existing tests already cover, and the operation-ID slots that this PR mirrors have neither.

Re-review — Final validation — Phase 1 + Phase 2
Verified the findings against a5dd3e8: two recovery paths still lose the recorded recipient and allow a different destination on resume, while Android persistence remains an untracked implementation gap. The raw-byte representation and backend capability declarations address two prior findings; the tracked-lock ABI blocker is withdrawn because the supported mixed-binary compatibility premise was not established. Current CI passes Rust workspace tests, Swift build/tests, Kotlin build/tests and frozen-schema checks; PR Hygiene remains pending, and no local builds or tests were run.

Recipient-bearing funding without an operation UUID reaches this branch, where queue_asset_lock_changeset logs store errors and returns no failure, and successful buffered stores are not flushed before broadcasting.

(existing thread: https://github.com/dashpay/platform/pull/5762#discussion_r4469356898)
remove_tracked_asset_locks_for_swept removes the complete live entry and emits a persistent deletion. When the original funding returns, this constructor supplies shielded_recipient: None and apply_record inserts it directly, so the existing-row preservation helper cannot restore recipient A; a subsequent generic resume accepts B. The pinned key-wallet implementation can sweep unconfirmed funding after a conflict in an ordinary InBlock context, so this sequence does not require reversing a finalized ChainLock. Coalescing sweep and reinstatement into one persistence round can also leave A preserved on disk while the live map has None, making protection differ before and after reload. A common recovery-metadata design is appropriate, but UUID parity does not preserve this new destination invariant, and #5528's UUID-bound retention does not cover non-UUID typed-amount locks. Retain non-actionable recipient metadata across removal and restart and reattach it on authenticated recovery, or fail closed. Extend the existing sweep/reinstatement regression with a recipient-bearing non-UUID lock.

(existing thread: https://github.com/dashpay/platform/pull/5762#discussion_r4469356955)
The current Android host takes this fallback: JNI extension_for leaves both recipient callbacks unset, and Room's AssetLockEntity has no recipient column. Newly created Android funding therefore loses its destination binding across restart and resumes with the caller's address. Withholding the capability accurately reports this limitation, and the behavior is not an Android regression, but it leaves the Android sibling of #5603 incomplete. Deferring implementation alongside the UUID sidecar is reasonable; it needs a linked tracking issue before it can be treated as a tracked deferral. A maintainer-owned follow-up covering the Room migration, JNI callbacks, capability attestation and restart round-trip is sufficient; implementing that work in this PR is not required.
…n-drain broadcast
A typed-amount Core -> Shielded funding only queued its row, so a store
failure was logged and nothing was flushed before the broadcast. A kill in
that window left a lock the chain can recover but whose recipient is gone,
and the resume then accepted any address.
On a backend that attests ASSET_LOCK_SHIELDED_RECIPIENTS, a recipient-bearing
funding without an operation UUID now stores and flushes its row before the
lock is tracked or sent, as the drain does. A failed store or flush aborts
before the broadcaster, releases the reservation and returns a Persistence
error. Identity, Type 14 and hosts without the capability are unchanged.

This failure branch calls abandon_unsent_build, releasing the reservation and input fence without retiring the possibly stored Built checkpoint. SqlitePersister::handle_flush_error restores transiently failed writes to its buffer, so a subsequent successful flush can commit this abandoned row; an inline backend can also commit store() before flush() fails. After restart, load_unconsumed restores the row and resume_asset_lock can broadcast its signed transaction even though this branch already returned its inputs for another payment or funding attempt. Not tracking the row in the current process does not make the persisted checkpoint non-actionable. Before releasing inputs, confirm that the checkpoint is removed from both buffered and durable state; if that cannot be established, retain a recovery checkpoint and the input hold until reconciliation. Extend the failure tests through a later successful flush and reopen, covering both a retained buffered row and a committed store followed by failed flush. The current buffered failure test verifies immediate absence from the committed map but does not verify retirement of the first attempt.

A newly recorded lock can reach this constructor after losing its recipient binding. TransactionsSwept calls remove_tracked_asset_locks_for_swept, which removes the complete live entry and emits a persistence removal. When the original funding returns through authenticated reconstruction, this constructor sets shielded_recipient to None and apply_record inserts it directly into the live map. resume_recipient then accepts another caller-supplied address. The pinned key-wallet permits conflict sweeps from provisional blocks, so this sequence does not require reversing ChainLock finality. It also fails within one folded persistence batch: SQLite can retain recipient A through COALESCE while the live row used by the resume check contains None. The new checkpoint explicitly covers recipient-bearing non-UUID fundings, whereas #5528 retains UUID-bound operation history. Preserve non-actionable recipient metadata in the Rust recovery owner across removal and reattach it on authenticated original-outpoint recovery, or fail closed until the association is recovered. Extend the existing sweep/reinstatement test with a recipient-bearing non-UUID lock, including folded-event and restart cases.

(existing thread: https://github.com/dashpay/platform/pull/5762#discussion_r4469356955)
This compatibility fallback still includes the current Android SDK: rs-unified-sdk-jni::extension_for leaves both recipient callbacks unset, and Kotlin's AssetLockEntity has no shielded-recipient column. Android therefore cannot attest ASSET_LOCK_SHIELDED_RECIPIENTS, bypasses the new capability-gated pre-dispatch checkpoint, and restores these locks without their destination. This is an unchanged Android limitation and a missed sibling of the recipient-recovery feature, so a separate implementation remains reasonable. Maintainer ownership of that work is also reasonable, but the supplied discussion and PR description contain no tracking reference. Link a follow-up issue or PR covering the Room migration, JNI store/load callbacks, capability declaration, and a store → restart → mismatched-recipient refusal test before treating the sibling implementation as deferred.
…heckpoint fails
A failed pre-dispatch checkpoint released the inputs while its Built row
could still be buffered (SQLite restores a transiently failed flush to its
buffer) or committed by a store that preceded the failed flush. A later
flush or a restart would then surface a resumable row for released inputs.
The row's removal is now queued behind it before the inputs are released.

Re-review — Final validation — Phase 1 + Phase 2
The recipient representation, ordinary resume checks, pre-dispatch durability gate, backend capability declarations, and Swift V5 migration are consistent with the intended design. Two blocking lifecycle gaps remain: abandoned checkpoints can survive input release, and sweep/reinstatement can erase the newly recorded recipient binding; Android’s deferred persistence implementation also needs tracking. This was a static review of daeb18d; current Rust, Swift, Kotlin, and frozen-schema checks pass, with PR Hygiene pending.

The removal is still best-effort: queue_asset_lock_changeset logs a failed store and returns (), after which abandon_unsent_build releases the reservation and input fence. FFIPersister provides a concrete counterexample to the inline-backend argument: the initial store commits through on_changeset_end_fn, the separate flush notification fails, and the cleanup round is rejected before deletion. The durable Built row then remains resumable after its inputs have been released. There is also a single-failure buffered sequence: this PR successfully flushes a recipient-bearing Built row on Manual SQLite, broadcast returns Rejected, and lines 1628–1659 only buffer the removal before releasing inputs. Reopening before another flush restores the abandoned signed transaction. Network double-spend protection does not prevent that transaction from winning against a replacement payment. Establish durable retirement before releasing inputs, or retain a recoverable checkpoint and input hold while retirement is uncertain. Cover committed-store/failed-flush/rejected-cleanup restoration and Manual-mode rejection followed by reopen.

(existing thread: https://github.com/dashpay/platform/pull/5762#discussion_r4469356898)
A newly recipient-bound lock becomes indistinguishable from a legacy lock on this supported recovery path. remove_tracked_asset_locks_for_swept deletes the live entry and emits its persistence removal; reconstruction then creates the same authenticated outpoint with shielded_recipient: None, and apply_record inserts it directly into the live map. Generic shielded resume consequently reaches resume_recipient(None, requested) and accepts recipient B instead of the recorded A. This affects non-UUID typed-amount locks on recipient-capable backends, including a folded persistence round where storage may retain A but the live map used by the check contains None. I verified that https://github.com/dashpay/platform/issues/5778 tracks the shared recovery design and is cross-referenced on this PR. That tracker does not resolve a bypass of the recipient-binding invariant introduced here; this is not merely a request to repair the older UUID behavior. Preserve non-actionable recovery metadata and reattach it when the original outpoint returns, or fail closed when a known binding cannot be restored. Cover the recipient-bearing non-UUID case both live and after reload.

(existing thread: https://github.com/dashpay/platform/pull/5762#discussion_r4469356955)
The current Android SDK takes this compatibility fallback: JNI extension_for leaves both recipient callbacks unset, and Kotlin AssetLockEntity has no recipient column. A newly created Android funding therefore restores without its recorded recipient and accepts the resuming caller’s address. Keeping Android non-attesting preserves its previous behavior, so a separate implementation is reasonable, but the stated deferral still has no linked tracker. Issue #5778 covers sweep/reinstatement, not JNI/Room persistence. Link a dedicated follow-up covering the Room migration, both recipient callbacks, restore hydration, capability attestation, and pre-dispatch durability with restart coverage; implementing that separate Android work is not required in this PR.
The remaining findings are deliberately deferred, not fixed here: recipient/UUID retention across sweep and reinstatement is tracked in #5778; the abandoned-checkpoint input hold is a lifecycle change for every non-drain asset lock and belongs in its own PR; Android recipient persistence follows with the UUID sidecar. The in-scope findings (non-shielded builds, capability attestation, pre-dispatch durability, withdrawal of the abandoned row) were fixed.

Closes #5603.
A Core → Shielded funding (Type 18
ShieldFromAssetLock) is two steps: the asset lock is broadcast first, the shield transition is submitted after the lock is proven. If the host app is killed in between, the transfer is resumed later from the tracked lock, butTrackedAssetLock/AssetLockEntrycarried no recipient, so both the genericshielded_resume_fund_from_asset_lockand a repeated-UUIDshielded_fund_from_wallet_drainbuilt the transition with whatever recipient the resuming call passed. dashwallet-ios works around this with an app-side marker for the wallet drain only (dashpay/dashwallet-ios#1251); typed-amount sends are uncovered (dashpay/dashwallet-ios#1253) and a Kotlin host would need the same machinery again.What was done?
Rust (
platform-wallet)TrackedAssetLockandAssetLockEntrygain one optional field,shielded_recipient: Option<ShieldedRecipientRaw>— the raw 43 bytes of the Orchard address, because these types, the SQLite persister and the FFI persistence layer are built without theshieldedfeature wheredpp::address_funds::OrchardAddressdoes not exist; only shielded code converts, and the resume check compares bytes (a corrupted recorded recipient matches nothing and is refused, not paid). (Address only; the pre-flight already refuses explicit per-recipient credits, so there is nothing else to record). It is set at the single row-creation site (build.rs::broadcast_funded_asset_lock_tracked, the former body ofbroadcast_funded_asset_lock_with_operation), and it is durable before dispatch: the row is stored and flushed before the lock is tracked or broadcast, for a drain and, on a backend that attestsASSET_LOCK_SHIELDED_RECIPIENTS, for a typed-amount funding too. A failed store or flush there aborts before the broadcaster, releases the reservation and returns aPersistenceerror (a behaviour change: such a funding used to proceed with only a logged store error). A host without the capability keeps the queued best-effort row. The recipient is threaded as a parameter fromresolve_funding_with_is_timeout_fallback; identity and Type 14 callers passNone.FromExistingAssetLock, which by then also covers a Pending repeated-UUID drain) the check runs right after recipient validation and before any funding resolution: the build pays the recorded recipient; a different one is refused with the new typedAssetLockRecipientMismatch(nothing reserved, waited for or sent; a drain's operation staysPendingwith its outpoint). Rows tracked before the recipient was recorded carry none and keep accepting the caller's. The caller-supplied recipient stays required and checked on both entry points, so no FFI/Swift/Kotlin signature changes.preserve_recovery_metadata(changeset merge andapply.rs) keeps it when a later snapshot lacks it and drops a snapshot naming another one.

The C header is generated by cbindgen at build time, so the new constant and struct fields appear automatically.Breaking Changes
None for hosts: FFI entry-point signatures are unchanged,
AssetLockEntryFFIis unchanged, the extension struct grows only through size negotiation.TrackedAssetLockFFIgains two trailing fields (hosts rebuild against the generated header). Rust:resolve_funding_with_is_timeout_fallbackand thecreate_funded_asset_lock_proof_*_observed/create_wallet_drain_asset_lock_proofhelpers take the new parameter (crate-internal callers updated).Checklist:
