Final validation — Phase 2 only (queue backlog)
The PR correctly batches the primary DPNS synchronization path and preserves the durable user selection. Two ownership/display edge cases remain: an empty canonical snapshot is indistinguishable from an unhydrated relationship, and several in-repository display surfaces still bypass the new owned-name projection. Identity discovery also continues to emit one-name snapshots, leaving transient and interruption-sensitive partial-state behavior in another startup path.

🟡 Suggestion: Batch DPNS names in discovery enrichment as well
packages/rs-platform-wallet/src/wallet/identity/network/discovery.rs:600-608
The discovery enrichment path still calls managed.add_dpns_name once per fetched username. Each call emits a full identity snapshot, while the Swift persister treats every snapshot as the complete canonical owned set. Although the new read-time filtering prevents the selected scalar from being overwritten, the first callback can still temporarily remove cache-only rows and make the selected name appear unowned until the later callback; an interrupted persistence sequence can leave that partial state behind. Collect the fetched usernames, merge them with the existing list, and persist one snapshot, or route discovery and the analogous identity-loading path through the corrected batching helper.

- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/Persistence/Models/PersistentIdentity.swift:271-278: Empty canonical snapshots can incorrectly trust a stale main DPNS name
`ownedMainDpnsName` treats an empty `dpnsNames` relationship as an identity that has never hydrated and returns `mainDpnsName` unchanged. However, `upsertDPNSNames` deletes cache-only rows when a canonical snapshot omits them, including when that snapshot is empty. For an identity whose selected name has no marketplace-history row, an empty snapshot can therefore remove the label row and leave `dpnsNames` empty while the sold or transferred `mainDpnsName` is still returned by `ownedMainDpnsName` and `displayName`. This can occur when a generic identity snapshot is emitted before DPNS enrichment completes. Track authoritative/hydrated state separately, or retain an explicit empty-snapshot marker, so only an identity that has never received a DPNS snapshot trusts the stored pick.
- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/Persistence/Models/PersistentIdentity.swift:266-276: Propagate owned-name semantics to all display callers
The new `ownedMainDpnsName` correctly separates the durable user selection from the owned-only display projection, but existing consumers still read `mainDpnsName` directly. For example, `DashPayProfileView`, `DashPayTabView`, and `StorageModelListViews` use the scalar for visible names, while the profile QR path can also pass it as the username. Those surfaces can therefore render or use a sold/transferred name even though `PersistentIdentity.displayName` filters it. Update display and operational callers to use `displayName` or `ownedMainDpnsName`; retain direct `mainDpnsName` only for selection/persistence UI. The adjacent `displayName` documentation should also describe the owned projection rather than claiming the priority is directly `mainDpnsName`.

Re-review — Final validation — Phase 1 + Phase 2
The PR correctly batches DPNS snapshots on the updated fetch paths and preserves the user-selected name without rewriting it during persistence. Two suggestion-level gaps remain: the public refresh path still replaces the cached list without persistence, and a same-wallet transfer can move the selected name row away from the old identity, causing its empty relationship to resurrect the stale selection. No blocking consensus or architectural issue was found.

🟡 Suggestion: Route refresh_dpns_names through merge_dpns_names and persist
packages/rs-platform-wallet/src/wallet/identity/network/loading.rs:443-451
refresh_dpns_names still assigns the query result directly to managed.dpns_names and does not call the new add-only persistence helper. get_dpns_usernames_by_identity(..., None) is capped at 10 results, so this public refresh path can replace an identity's cached list with an incomplete result and lose previously known labels, contrary to the add-only invariant used by sync, discovery, and identity loading. Route this path through merge_dpns_names (or paginate until the complete set is known) so it has the same semantics as the other DPNS fetch paths.

`ownedMainDpnsName` treats an empty `dpnsNames` relationship as an unhydrated identity and returns the stored pick. That relationship is not a stable hydration marker: `upsertDPNSNames` enforces one unique row per network/domain/label and rebinds the row to the new owner. If identity A has selected `Alice` and Alice transfers to identity B in the same wallet, B's snapshot moves the row from A to B while A's `mainDpnsName` remains `Alice`; A then has no rows and this accessor returns the stale pick as if it were still owned. Persist an identity-level hydration/known-ownership marker, or retain departure evidence on the old identity, and extend `testSameWalletTransferRebindsSingleCanonicalRowToNewOwner` with a selected name on the old owner plus an `ownedMainDpnsName == nil` assertion.

Verified the complete diff at b81bfe0. Batching and selection preservation address the reported two-name refresh failure, but three non-consensus ownership/cache issues remain; under the supplied severity policy, these are suggestions rather than blockers. All 1,166 platform-wallet library tests and the diff whitespace check passed; Swift behavior was verified by source inspection, not by rerunning Swift tests.

- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/Persistence/Models/PersistentIdentity.swift:278-279: Do not hide an owned pick solely because a capped fetch omitted it
The stated cold-start fix remains incomplete when the selected name falls outside the first ten results. buildIdentityRestoreBuffer still restores an empty Rust DPNS list, and the changed network fetch paths pass None to get_dpns_usernames_by_identity, which defaults to ten results without pagination. The first merged snapshot therefore contains only that page. upsertDPNSNames marks the persisted selected row not owned, and this accessor hides the still-owned selection. Repeating syncDpnsNames cannot recover it because the same page adds nothing; recovery requires another path such as marketplace sync. Restore the known names before publishing merged snapshots, or establish complete ownership evidence before treating an omitted selection as departed. Add a cold-start regression with the selected name outside the first ten results and assert the displayed name, not only the stored selection.
- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/Persistence/Models/PersistentIdentity.swift:291-295: Keep identity hydration state independent of transferable name rows
(existing thread: https://github.com/dashpay/platform/pull/4978#discussion_r4099000468)
The cross-identity lookup suppresses a transferred selection only while the recipient's row survives. When A selects its sole name Alice and B's snapshot rebinds that unique row to B, A retains its selection but has no related rows. Removing B's wallet through deleteWalletData explicitly deletes B's name rows; alternatively, a later empty snapshot deletes B's cache-only Alice row when it is not B's selected name. A then has neither related rows nor a globally discoverable Alice row, so this return displays Alice again without reacquisition. An empty snapshot for A cannot repair this because upsertDPNSNames has no associated row to mark unowned. Persist identity-scoped departure or hydration evidence when rebinding the row, and extend the transfer regression through deletion of the recipient's local data.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/loading.rs:447-453: Keep ownership reconciliation independent of marketplace tracking
Changing refresh_dpns_names from replacement to an additive merge also removes its ability to clear departed names, including when a successful query returns no usernames. A watched identity with one cached name now retains that name indefinitely after it disappears from the query results. Marketplace reconciliation does not cover this identity: refresh_dpns_names iterates all_identities(), including out-of-wallet identities, while sync_dpns_marketplace enumerates wallet_identity_ids and remove_dpns_label uses wallet_identity_mut. Preserve the capped-result protection, but distinguish complete results from partial enrichment and reconcile departures for the same identity set that refresh supports. Add a watched-identity regression where the cached name disappears, alongside the capped-result preservation test.

Re-review — Final validation — Phase 1 + Phase 2
The batching, complete-result reconciliation, and transfer handling fix five of the seven prior findings. Four non-consensus SDK correctness issues remain: capped cold-start fetches can hide an owned pick, scalar-only identities can retain a departed display name, pruning can bypass marketplace departure processing, and a nil display cache prevents fallback to another owned name; these are suggestions under the project's severity policy. At head 942f7b0, all 1,170 Rust wallet library tests and the PR diff whitespace check passed; Swift behavior was verified statically, and the worktree remains clean.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/state/managed_identity/identity_ops.rs:294-299: Preserve marketplace departure tracking before pruning labels
A complete username fetch now removes labels that marketplace sync still needs to process. `sync_dpns_marketplace` snapshots `ManagedIdentity.dpns_names` and builds `pending_departures` exclusively from that list; its existing marketplace rows are used to resolve departures, not discover them. If `sync_dpns_names` runs after an external sale, transfer, or deletion but before the marketplace sweep, this filter removes the departure's only trigger. The later sweep consequently misses the history/state update, departure notification, and sale-triggered balance refresh, and can retain a stale marketplace entry. Queue departures before pruning, or reconcile tracked marketplace rows independently of the current owned-label list. Add a regression covering username sync followed by marketplace sync after a departure.

The remaining fallback only runs when `dpnsName` is already non-nil. That is not guaranteed: canonical name insertion does not initialize it, and `updateMainDpnsName` and the selection screen update only the main selection. Persist Alice and Bob, select Alice with `dpnsName == nil`, then apply a snapshot containing only Bob. Alice's retained pick is correctly hidden, but the display cache stays nil and `displayName` falls back to the truncated identity ID instead of Bob. Previously the removed main-name fallback selected Bob. Preserve the raw pick while initializing a separate owned-name fallback when the display cache is absent or invalid, and test this sequence without pre-seeding `dpnsName`.

(existing thread: https://github.com/dashpay/platform/pull/4978#discussion_r4105177663)
The partial-fetch merge protects names already cached in Rust, but `buildIdentityRestoreBuffer` explicitly restores zero DPNS names. For an identity owning more than 100 names whose pick is outside the first page, the cold-start merge therefore emits a snapshot containing only that page. `IdentityEntry` carries no completeness marker, and Swift's `upsertDPNSNames` treats the list as canonical, marking the omitted picked row not owned. This accessor then hides a name the identity still owns. Repeating the username fetch cannot recover it because the SDK query always uses `start: None`. Restore the persisted owned-name cache before merging, carry partial-update semantics through persistence, or fetch the complete set before publishing a replacement snapshot. Cover a cold restore with the selected name beyond the first page.
- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/Persistence/Models/PersistentIdentity.swift:291-295: Empty canonical snapshots can incorrectly trust a stale main DPNS name
(existing thread: https://github.com/dashpay/platform/pull/4978#discussion_r4096796799)
Retaining an existing picked-name row does not cover a persisted scalar-only selection. Start with `mainDpnsName = "Alice"` and no DPNS rows, then apply an authoritative empty ownership snapshot after Alice has left the identity. `upsertDPNSNames` has no row to mark not owned, inserts nothing, and leaves the selection intact. With no matching row belonging to another local identity, this getter still returns Alice, so `displayName` advertises the departed name despite the empty snapshot. Record confirmed ownership hydration independently, or materialize a not-owned marker for an omitted pick when processing an authoritative snapshot. The current empty-snapshot test starts with an Alice row and does not cover this sequence.

At ffb9ef6, seven prior findings are fixed; two remain: username reconciliation can lose marketplace departure candidates, and capped cold-start fetches can still hide an owned selection. The pagination loop also lacks direct regression coverage. These are non-consensus suggestions under the project's severity policy; verification covered the complete diff and relevant lifecycle paths, and git diff --check passed, but runtime tests were not rerun.

- [SUGGESTION] packages/rs-sdk/src/platform/dpns_usernames/queries.rs:293-299: Exercise the actual DPNS pagination loop in SDK tests
The paging tests only call next_dpns_page with a supplied last document ID; none invokes get_all_dpns_usernames_by_identity. They would therefore pass if the loop stopped forwarding StartAfter, selected the wrong cursor, discarded earlier pages, or returned the wrong completeness value after exhausting max_pages. That completeness value now authorizes removal of cached names. Add network-free mock-SDK tests that verify the actual requests and accumulated results for a full page followed by a short or empty page, budget exhaustion returning complete=false, and a later-page error propagating. Also cover a document skipped during conversion so cursor advancement and termination remain based on the raw page rather than the converted usernames.

(existing thread: https://github.com/dashpay/platform/pull/4978#discussion_r4107974903)
A complete username fetch removes the only departure trigger when the identity has a cached label but no corresponding session marketplace row. This occurs before the first successful marketplace sweep, including after loading a wallet: manager/load.rs initializes dpns_name_states empty, and local_dpns_name_states explicitly documents that it is not rehydrated. Once this filter removes the label, departure_candidates sees neither that label nor an Owned row, so resolve_departed_name is never called and its persisted-row lookup cannot recover the departure. Sale/transfer classification, stale marketplace-row cleanup, and the sale-triggered balance refresh are consequently skipped on subsequent sweeps. The new regression seeds info.dpns_name_states, so it only verifies the populated-cache case. Retain removed labels as pending departure work, or make durable tracked rows available to candidate discovery, and test complete username reconciliation followed by marketplace sync with an initially empty session map.

- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/Persistence/Models/PersistentIdentity.swift:278-279: Do not hide an owned pick solely because a capped fetch omitted it
(existing thread: https://github.com/dashpay/platform/pull/4978#discussion_r4105177663)
Pagination still produces a partial set when an identity owns more than 1,000 names. On Swift cold restore, buildIdentityRestoreBuffer supplies no DPNS names, so apply_fetched_dpns_names(..., false) merges the first ten pages into an empty Rust list. merge_dpns_names then emits an ordinary replacement snapshot through set_dpns_names; neither IdentityEntry nor IdentityEntryFFI carries completeness. Swift's upsertDPNSNames therefore marks an omitted picked-name row not owned, and this accessor hides the selection even though ownership did not change. Retaining the raw pick does not preserve its displayed ownership, and repeated capped username fetches restart at the beginning rather than recovering names beyond the bound. Preserve partial-result semantics through persistence, hydrate previously owned names before merging, or prevent an incomplete cache from emitting an authoritative replacement. Add a cold-start regression with a persisted pick outside the fetched prefix; the existing partial-fetch Rust test already has the omitted name in memory.

Re-review — Final validation — Phase 1 + Phase 2
Verified the complete reviewed range at 78b0e0e: eight prior findings are fixed, while departure-work recovery and the previous owner's display fallback remain incomplete. These are non-consensus correctness suggestions, not blockers under the project's severity policy. All 42 focused wallet tests and 19 SDK DPNS tests passed; two temporary regressions independently reproduced departure loss after backend failure and identity replay, then were removed, leaving the worktree clean; Swift behavior was verified by source inspection.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/state/managed_identity/mod.rs:83-91: Preserve marketplace departure tracking before pruning labels
The queue preserves the successful same-session handoff, but two recovery paths still discard the only departure candidate after a complete username fetch prunes it.
First, `set_dpns_names` persists the reduced owned set, while `IdentityEntry::from_managed` excludes `pending_dpns_departures`. Restarting before classification restores neither the departed label nor its pending work. The session marketplace map starts empty, and Swift restores only `isOwned` labels, so retaining a durable marketplace row does not supply a candidate to the next sweep.
Second, `sync_dpns_marketplace` clears the managed queue at line 1737 before resolving its entries. The `DepartureResolution::Failed` arm consumes the progress entry because it assumes the original label remains available for rediscovery. That assumption is false after pruning: with no session marketplace row, repairing a fatal persistence-read failure does not allow the next sweep to finish reconciliation.
I independently reproduced both paths with temporary regression tests: identity replay after pruning and a prune/fail/heal sequence both returned no departures. Preserve pending work durably alongside the ownership snapshot, and retain unresolved failed entries for later passes without blocking other candidates. Acknowledge the work after reconciliation is durably applied, rather than when it moves into an in-memory queue.

- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletPersistenceHandler.swift:3766-3773: Provide an owned-name fallback when dpnsName is nil
(existing thread: https://github.com/dashpay/platform/pull/4978#discussion_r4107974914)
The new fallback repairs only the identity receiving the snapshot, although this rebind also clears the previous owner's display fields. Let A own Alice and Bob, with both `mainDpnsName` and `dpnsName` set to Alice, then process B's snapshot after Alice transfers to B. This block correctly clears A's selection of Alice, but the fallback at lines 3819–3821 runs only for B. A still owns Bob, yet `displayName` returns its truncated ID and callers using `ownedMainDpnsName ?? dpnsName` find no username. Nothing in this persistence call repairs A unless another snapshot for A arrives. Apply an owned-name fallback to every owner affected by rebinding, or centralize the effective fallback in the model and use it from display consumers. Extend the transfer regression with a second name retained by the previous owner.

Re-review — Final validation — Phase 1 + Phase 2
Verified the complete diff at c8ce2d8. Ten prior findings are addressed, but standalone ownership refresh still retains departed wallet-owned names, and cached snapshots can now permanently clear another identity's valid selection. Both are suggestions under the project's non-consensus correctness policy; validation consisted of source tracing, regression-test inspection, and a passing diff whitespace check, without rerunning runtime tests.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/state/managed_identity/identity_ops.rs:296-298: Keep ownership reconciliation independent of marketplace tracking
A complete fetch now remains add-only for every wallet-owned identity. If an identity previously held Alice and `refresh_dpns_names()` subsequently receives a complete empty result, the refresh succeeds but leaves Alice in `dpns_names`; later snapshots continue advertising it as owned. Before this PR, that refresh replaced the list. The watched-identity replacement branch does not address this wallet-owned case, and neither the helper nor `refresh_dpns_names()` invokes the marketplace sweep. `DpnsSyncManager` is explicitly not auto-started, so a standalone caller can retain the departed name indefinitely. Preserve the marketplace's departure-classification trigger separately and durably while updating current ownership, or make the refresh perform ownership reconciliation itself. Add a regression for a wallet-owned identity whose complete refresh is empty with marketplace synchronization disabled.

- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletPersistenceHandler.swift:3760-3768: Do not permanently clear a pick based on a cached ownership snapshot
This rebind does not establish a confirmed transfer: `apply_fetched_dpns_names` deliberately retains departed labels for wallet-owned identities, and a balance refresh persists those same labels through `snapshot_changeset()` and `IdentityEntry::from_managed`. After an external A-to-B transfer, B's username sync can rebind the name to B while A still carries it in Rust. If the user selects that name for B, a subsequent balance snapshot for A reaches this branch, rebinds the row back to A, and permanently clears B's valid selection. Marketplace synchronization can leave this window open across failed or bounded departure processing; later ownership reconciliation cannot reconstruct the erased preference. Require confirmed ownership/departure evidence before clearing another identity's selection, or retain independent departure evidence so cached snapshot rebinds remain reversible. Add a regression covering B's acquisition and selection, a stale A snapshot, and subsequent ownership reconciliation.

Review — c8ce2d8The fix itself reads right: one snapshot per fetch on the Rust side, the pick treated as user data on the Swift side with the owned-only check moved to read time, and the cold restore seeding Rust with the persisted owned labels so a capped fetch can only add. The Swift tests pin each regression the bot found along the way, and the mock-SDK paging tests are keyed on the exact request, which is the right level. One thing I could not confirm from the code and would like checked before merge, plus a test-coverage gap and a few nits. 1.

Re-review — Final validation — Phase 1 + Phase 2
At head 202df9a, the complete diff addresses chosen-name preservation through batched snapshots, restored owned labels, conservative pagination completeness, and ownership-aware display reads. Ten prior findings are fixed and three remain explicitly deferred to #5019; independent verification found no additional in-scope findings. This was a static review with no local builds or tests: the supplied exact-head CI snapshot reports successful Rust workspace tests and Swift SDK build/tests, while the separate Rust wallet job was skipped and PR Hygiene remains pending.

Out-of-scope follow-up suggestions (2)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Separate durable departure tracking from current ownership and preference clearing (#5019) — The limitation remains concrete: apply_fetched_dpns_names merges even complete wallet-owned fetches, IdentityEntry::from_managed copies those retained labels into balance snapshots, and Swift snapshot-driven rebinding clears the previous owner's matching selection. An unrelated stale snapshot can therefore erase the recipient's valid pick, while standalone refresh cannot independently remove departed ownership. The author explicitly tracks this shared ownership/departure design repair in #5019; it is not a completed fix or a new finding to reopen here.
- Follow-up: Use #5019 to persist departure evidence separately from current owned labels and convey confirmed ownership evidence to Swift before clearing another identity's preference. Cover marketplace-disabled refreshes and stale snapshots following a same-wallet transfer.
- Apply the historical cursor capability policy to marketplace pagination — The unchanged dpns_domain_states_page uses records.identity equality with StartAfter and no orderBy, then treats a short response as complete. The Drive lowerings and added regression tests establish that the v0 lowering returns an empty continuation inside this bucket, so this independent pager can truncate identity domain-state enumeration and falsely complete a marketplace ownership scan. The same implementation exists in the supplied base, making this a concrete pre-existing follow-up rather than a change required in this PR.
- Follow-up: Address this in a separate issue or maintainer-requested PR with capability-aware completeness handling and marketplace regression coverage for the v0 lowering. Preserve shipped Drive behavior.

The username picked in Identities -> identity -> Usernames reverted to another owned name on every launch. The pick lived only in the SDK column PersistentIdentity.mainDpnsName, and the SDK rewrote it from a partial DPNS snapshot during startup sync (fixed SDK-side in dashpay/platform#4978). Keep an app-owned copy of the pick in UserDefaults, one slot per identity (like the main-identity pick), and make every reader prefer it: the identities list and detail page, and the DashPay username snapshot. The create-username promotion writes the copy when it stores the new main name, a manual pick writes it, and a wallet wipe clears it with the pending promotions. The SDK column is still written for anything that reads it directly. Ownership and pending-contest filters are unchanged. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Issue being fixed or feature implemented
When an identity owns several DPNS names, the name the user picks to display (
PersistentIdentity.mainDpnsName) is lost on every app launch and replaced by another owned name. Reported by a Dash Wallet iOS user; reproduced on the simulator.Two defects combine:
sync_dpns_namesadds the fetched names one at a time, and eachadd_dpns_namepersists a full identity snapshot. On a cold start the in-memory list is empty, so the first snapshot carries a single name.upsertDPNSNamesreads every snapshot as the complete owned set and rewritesmainDpnsNametonames.firstwhen the pick is missing from it (added with the marketplace in feat(platform-wallet): wallet-level DPNS username marketplace with FFI and Swift wrappers #4348). The partial snapshot therefore overwrites the pick, and the full one that follows 16 ms later cannot bring it back.What was done?
Sdk::get_all_dpns_usernames_by_identity(new, rs-sdk) follows aStartAftercursor until a page comes back short and reports whether the set is complete (100 per page, at most 10 pages).ManagedIdentity::apply_fetched_dpns_names(new,identity_ops.rs) applies one fetch as one snapshot. For an identity the wallet only watches, a complete set replaces the list (departed names drop out, an empty set clears it, known labels keepacquired_at, nothing is stored when unchanged). Wallet-owned identities, and any incomplete set, only merge (merge_dpns_names): the marketplace sweep discovers a wallet identity's departures from this list, so a username fetch never prunes it first.sync_dpns_names, identity discovery (discovery.rs), identity loading andrefresh_dpns_names(loading.rs) all go through it. They used to add names one at a time (discovery and loading without deduplication), andrefresh_dpns_namesreplaced the list with a single capped page without persisting it.buildIdentityRestoreBufferfillsIdentityRestoreEntryFFI.dpns_namesfrom the identity's ownedPersistentDPNSNamerows (it restored none; the Rust side already consumed the field).ManagedIdentity.dpns_namestherefore starts complete-as-known, so a capped fetch only adds to it and no snapshot carries a truncated owned set — an owned pick outside the fetched prefix stays owned.sync_dpns_marketplacestill finds every departure in the list (and among theOwnedrows it tracks) and classifies it — across restarts too, since restore re-seeds the list.PlatformWalletPersistenceHandler.upsertDPNSNamesno longer writesmainDpnsName: the pick is user data. When a snapshot omits the pick, its row is kept and marked not owned instead of being deleted; a pick with no row at all gets a not-owned row, so an authoritative snapshot is recorded rather than the pick being trusted as unhydrated. When a row is rebound to another identity (a transfer within the wallet), the previous owner's pick of that name is cleared.dpnsName(the SDK's display cache) falls back to an owned name when it is unset or departed.PersistentIdentity.ownedMainDpnsName(new) returns the pick only while the identity still owns it; with no label rows at all, the pick is trusted, unless the name's row (unique per network) now belongs to another identity, as after a transfer within the wallet.displayNamereads through it, so a sold or transferred name still falls back as feat(platform-wallet): wallet-level DPNS username marketplace with FFI and Swift wrappers #4348 intended — the check has moved from write time to read time.DashPayProfileView,DashPayTabView,CreateInvitationSheet,IdentitiesView,IdentityDetailView,StorageModelListViews) readownedMainDpnsName. The rawmainDpnsNamestays only on the selection screen and in the storage inspector.How Has This Been Tested?
cargo test -p platform-wallet --lib: 1172 passed, includingmerge_dpns_names_persists_one_complete_snapshot, theapply_fetched_dpns_namescases (watched identity: replace/clear/unchanged; partial: merge;complete_dpns_fetch_on_a_wallet_identity_only_adds, which fails if a wallet identity is pruned), andsync_pass_resolves_a_departure_whose_label_was_already_pruned.cargo test -p dash-sdk --lib dpns: 19 passed. New network-free mock-SDK tests driveget_all_dpns_usernames_by_identityitself: full + short page, full + empty page, page-budget exhaustion (complete == false), a later-page error propagating, and an unparseable document that still fills the page and moves the cursor. Each expectation is keyed on the exact request, so a wrong cursor fails; mutations (first-key cursor, budget exhaustion reported complete, page length taken from converted usernames) each fail a test.cargo test -p platform-wallet-ffi --lib: 385 passed, includingrestored_identity_carries_its_persisted_dpns_names.cargo clippy -p platform-wallet -p dash-sdk -p platform-wallet-ffi --all-targets -- -D warningsandcargo fmt --checkare clean.swift test --filter DpnsMarketplacePersistenceTests: 12/12 (other restore-buffer suites —IdentityKeyContractBoundsTests,IdentityIsLocalPersistenceTests,DashPay*PersistenceTests— also pass).testColdRestoreCarriesEveryOwnedNameToRust: the restore buffer carries every owned label (a pick included) and no not-owned one. It fails when no names are restored.testCanonicalSnapshotsHideDepartedHistoryAndDeleteCacheOnlyRowsis updated: the pick stays in the column, whileownedMainDpnsName/displayNamefall back.testMainNamePickSurvivesAnIncompleteSnapshot: a snapshot missing the pick, then the full one, keeps it. It fails with the old reset restored.testDepartedCacheOnlyPickIsNotDisplayed: a cache-only pick that leaves through an empty snapshot keeps its row as not owned and is not displayed; owning it again brings it back. It fails if the row is deleted.testSameWalletTransferRebindsSingleCanonicalRowToNewOwnernow also checks that the old owner's pick is cleared and not displayed after the transfer, including once the recipient's row is gone.testDisplayFallsBackToAnOwnedNameWhenTheDisplayCacheIsNilandtestScalarOnlyPickOmittedBySnapshotIsNotDisplayed; each fails without its fix.SwiftExampleApp builds for the simulator.
End to end (first commit): the same change was applied to the SDK of the shipped Dash Wallet iOS 9.1.0 build on testnet (iOS 26.5 simulator), with an identity holding two names.
New
testPreviousOwnerFallsBackToAnotherOwnedNameAfterTransfer: after a transfer the previous owner shows its remaining owned name; fails without the fallback.Breaking Changes
None in the API. One behaviour change: a consumer reading
mainDpnsNamedirectly now sees the pick even after that name was sold. UseownedMainDpnsNameordisplayNameto get the owned-only value. Dash Wallet iOS already filters departed names on read.Checklist:
