Final validation — Phase 2 only (queue backlog)
The PR implements the contact-account registration and historical rescan behavior, and the Rust changes are covered by targeted tests. Three correctness issues remain: Core-to-Core balance gating aggregates all BIP44 accounts while funding is fixed to account 0; the CI script masks all default-keychain lookup failures; and an unvalidated contact-request height can be used as a scan checkpoint, allowing a malicious or malformed request to skip historical payments.

🟡 Suggestion: Align the Core balance gate with the account-0 funding path
packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Core/Views/SendTransactionView.swift:489-492
coreBalanceSnapshot() sums confirmed balances across every BIP44 account, but the Core-to-Core path now always passes senderAccountIndex: 0 to finalizeAtomic. A wallet funded only in another BIP44 account can therefore pass the UI balance gate and enable Send even though account 0 cannot fund the transaction. Gate Core-to-Core sends using account 0's confirmed balance, including the required fee, or choose a funded account and pass that same index to finalizeAtomic.

- [SUGGESTION] packages/swift-sdk/run_tests.sh:26-30: Do not ignore every default-keychain lookup failure
The `|| true` applies to the entire `security default-keychain -d user | sed ...` pipeline. As a result, permission errors, an unavailable `security` command, and other failures are treated the same as the documented no-default-keychain case. The script can then change the default keychain while retaining an empty previous value, causing cleanup to skip restoration. Handle only the known no-default-keychain result as an empty value and propagate or report other lookup failures before changing keychain state.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/contacts.rs:40-55: Validate the contact-request height before using it as a scan checkpoint
The checkpoint uses the minimum `core_height_created_at` from contact requests whenever the account-reference check passes, but it does not validate that the height is a plausible locally known Core height. A malicious or malformed contact request can claim an arbitrarily high height. When the wallet has already scanned beyond that value, `previous_checkpoint.min(scan_checkpoint)` preserves the already-advanced checkpoint, so the wallet does not revisit blocks containing payments to the newly registered contact account. Treat invalid or unknown heights as unavailable and fall back to the wallet birth boundary, or clamp accepted heights to a locally known Core tip before updating the checkpoint.

Both review phases and the independent verifiers still ran, but on weaker models, with Phase 1 capped athigheffort. Treat the verdict as provisional; a full-strength re-review will run on the next push once the primary models are back.
PR #4740's contact-rescan fix, Core account-0 alignment, and keychain hardening all verify clean at this head. All three prior findings are fixed; the residual upper-bound claim is refuted because heights are platform-stamped and both call sites can only rewind. Two in-scope maintainability suggestions remain.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/contacts.rs:40-44: Name the DIP-15 rotation-bit shift instead of inlining `>> 28`
The `request.account_reference >> 28 == 0` test re-derives the DIP-15 layout (low 28 bits masked index, top 4 bits rotation version) whose canonical owner is `rs-platform-encryption` (`calculate_account_reference`/`unmask_account_reference` in `account_reference.rs`). The same literal shape appears as `1 << 28` in the payments.rs tests, so a future layout change must be found by text search across three sites. Behavior is correct today and the fallback (rewind to wallet birth) is the safe direction, so this is maintainability only: a shared named constant or a secret-free version-bit accessor in the owning crate would keep the single source of truth.
In `packages/swift-sdk/run_tests.sh`:
- [SUGGESTION] packages/swift-sdk/run_tests.sh:30-32: Exact keychain error-string match is brittle across macOS images
The lookup-failure classifier requires byte-exact equality with one English `security` message. Locale is pinned via `LC_ALL=C`, but if a macOS/Xcode image rewords that string, a genuinely absent default keychain falls into the abort branch and fails CI loudly. That direction is fail-safe (no keychain state is touched before the exit), so this is robustness only: a substring match on the stable core (`A default keychain could not be found`) would keep the intended absent-vs-denied distinction working across images.

…count's own request The contact scan checkpoint pooled both directions' requests, so a contact could drag our receiving account back to the wallet-birth floor by publishing a rotated or older request, and clear its rescan guard with every re-key. - `contact_scan_checkpoint` takes a `ContactAccountSide`: the receiving account follows only our outgoing request, the external account only the contact's incoming request. It still falls back to the birth floor for an unknown, height-less or rotated request, and is still combined with the previous checkpoint under the same lock. - `register_contact_account` marks the rescan guard for every relationship it covered, pending ones included, so the next DashPay sync does not rewind the same range again. Only changes to our outgoing request clear the guard; incoming-side events no longer do. - Docs name the Platform-assigned `$createdAtCoreBlockHeight` as the trusted checkpoint source (it raises `synced_height`, which prunes state up to that height) and describe registration at send time instead of the removed funding-height model. - platform-encryption exposes `account_reference_version` / `ACCOUNT_REFERENCE_VERSION_SHIFT` in place of the magic `>> 28`.

Core payments funded from BIP44 account 0 while shielding from Core used the largest BIP44 account. The displayed Core balance also changed with the typed destination, and the insufficient-funds alert said "BIP44 account 0". Both Core-funded flows now use the pooled Rust default at `coreFundingAccountIndex`: BIP44 and BIP32 at that index plus every DashPay receiving account (`SEND_FUNDING_SOURCES` == `ASSET_LOCK_FUNDING_SOURCES`). The Core balance shown is exactly that set's confirmed total, for every flow. The account predicate lives in `isCoreFundingSource`, the view no longer passes a literal 0, and the alert reads in plain language. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

… rescans by the earliest request - A contact could force rescans by rotating their request. The rotation rebuilds our watch-only `DashpayExternalAccount`, and that rebuild rewound `synced_height` to wallet birth and bumped the account generation. External accounts now go back to `insert_funds_bearing_account`, so a rebuild neither rewinds the scan nor bumps the generation. Upstream key-wallet already leaves external accounts out of balance and coin selection, so the #649 spend pruning cannot reach our funds through them. Our payments to the contact spend our own inputs, so they are still matched. - The receiving checkpoint now uses the earliest `$createdAtCoreBlockHeight` of any of our sent docs to that contact. Before, it used the newest tracked request. The sweep records these heights before collapsing docs to the newest one per recipient. They live in memory only: the sent cursor also resets on a cold start, so every process's first sweep refetches all sent docs before `reconcile_dashpay_rescan` runs. A version-0 re-send no longer raises the checkpoint, and a rotated relationship now has a real lower bound instead of wallet birth. When no earliest height is known, the old birth-floor fallback still applies. If a sweep finds an older publication than the checkpoint already applied, it clears the rescan guard so the gap gets backfilled. - Replaying an established contact (`apply_established_contact`) no longer clears the rescan guard, so a same-process replay after registration cannot trigger a second rewind. - Test hygiene: new tests use `should_` names, drip-feed and forward-covered test docs describe the current behaviour, and the leftover function-local duplicate imports are gone.

…letes The earliest-height map is filled only by sync sweeps. So before this process has fetched and ingested its sent requests, a receival contact missing from the map has only the tracked (newest) request to go on. A version-0 re-send there would put the checkpoint above the first publication of our receiving xpub. Each identity now keeps an in-memory `sent_sweep_completed` flag, set when the sent fetch succeeds and every ingest reaches disk. Until it is set, `reconcile_dashpay_rescan` defers contacts that have no earliest-height entry: it neither rewinds nor sets the guard, and the next successful sweep reconciles them against the real earliest height.

Re-review — Final validation — Phase 2 only (queue backlog)
Verified two in-scope issues: reconciliation can lose a checkpoint rewind to an in-flight scan commit, and a pagination-limited fetch can prematurely certify sent-history completeness. Both are non-consensus wallet correctness issues, classified as suggestions under the supplied severity policy. All 1,192 targeted library tests and the complete-diff whitespace check passed; the worktree remains unchanged.

🟡 Suggestion: Invalidate in-flight scans when reconciliation lowers the checkpoint
packages/rs-platform-wallet/src/wallet/identity/network/payments.rs:183-188
The new older-publication re-arm path lowers an existing receiving account's checkpoint without invalidating its scan generation. In the pinned rust-dashcore revision e4208c9, scan_batch skips per-wallet heights at or below the checkpoint captured at scan time, while try_commit_batches checks generation equality and contiguity against the batch start—not that captured checkpoint. During multi-wallet synchronization, a batch covering 5000–9999 can therefore scan this wallet at checkpoint 9000, then commit after reconciliation rewinds it to 7499: the generation still matches and 7500 >= 5000 passes the contiguity check. The commit raises the checkpoint to 9999 although this wallet's filters at 7500–9000 were never checked. Reconciliation has already set rescan_triggered, so later sweeps do not repair the missed interval in this process. Registration's generation bump does not protect this later rewind. Atomically invalidate the scan certificate when reconciliation lowers the checkpoint, and add a regression covering an older publication discovered between scanning and committing a batch that spans both checkpoints.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/contact_requests.rs:1640-1642: Distinguish pagination exhaustion before marking the sent sweep complete
`sent_ok && sent_persist_ok` proves that the returned batch was fetched and persisted, not that the sent history was exhausted. The SDK's `fetch_contact_requests_paginated` returns `Ok` after 50 full pages of 100 documents even when more remain, and `fetch_sent_contact_requests` uses that same limit. On a cold start with more than 5,000 sent documents, restored contacts outside the returned batch can consequently have no earliest-height entry when this flag becomes true. `reconcile_dashpay_rescan` then stops deferring them and uses their newest tracked version-0 request height, or wallet birth for a rotated request, before their earliest publication is known. This can produce an incomplete initial backfill requiring another rewind, or an unnecessarily deep scan. Expose exhaustion/continuation status from the SDK helper, retain the page budget and cursor advancement, and mark the sent sweep complete only after the backlog is exhausted and ingestion succeeds. Add a regression where a restored contact outside a budget-limited batch remains deferred until the completing fetch.

Re-review — Final validation — Phase 1 + Phase 2
Reviewed the complete diff at 504a717 and confirmed one non-blocking test-coverage gap: two registration-guard regressions pass even when registration no longer sets the guard. The pagination-completion and reconciliation invalidation limitations remain explicitly deferred to #4955; no additional blocking defects were identified. All 1,195 wallet and encryption library tests passed with locked, offline dependencies, and the worktree is unchanged after mutation verification.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/payments.rs:3082: Complete the sent sweep before testing registration's rescan guard
Both `should_not_rewind_again_after_fresh_send_registration` and `should_not_rewind_again_when_established_contact_is_replayed_after_registration` seed requests through the apply path, leaving `sent_sweep_completed` false and the earliest-height map empty. Without the registration guard, reconciliation therefore still returns `None` through its pre-sweep deferral branch, so these assertions do not detect a missing or cleared guard. I independently removed registration's guard insertion temporarily and confirmed that both tests still passed. Mark the sent sweep complete before reconciliation in both tests, or ingest a successful sweep containing the same outgoing request, so losing the guard causes the unwanted rewind and fails the assertions.
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.
- Expose atomic checkpoint rewind and scan invalidation in key-wallet — The pinned key-wallet implementation updates synced_height and prunes observed spends without changing account_generation. The SPV commit path can therefore accept a previously scanned batch when the rewound checkpoint still satisfies batch-start contiguity. This is the documented reconciliation limitation, also relevant to the general rescan entry point, and is explicitly deferred rather than fixed here.
- Follow-up: Use the existing #4955 follow-up to add an upstream atomic rewind-and-invalidate operation, test stale-batch rejection, and route both rescan entry points through it.
- Report pagination exhaustion from the SDK contact-request helper — The SDK returns the same successful collection after exhaustion and after its 50-page budget stop. Consequently, successful ingestion can mark a sent sweep complete while restored contacts outside that batch still lack their earliest publication height. This concrete SDK result-contract limitation is explicitly deferred to #4955.
- Follow-up: Expose exhaustion or continuation information while preserving bounded fetching, and test that a restored contact outside the first budgeted batch remains deferred until its history is covered.
…egistration guard Without a completed sent sweep, reconcile_dashpay_rescan returns early through its pre-sweep deferral, so the guard tests passed even with the registration guard removed. Mark the sweep complete so only the guard prevents the rewind. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Re-review — Final validation — Phase 1 + Phase 2
Reviewed the complete diff at f9426a4 and found no remaining in-scope findings; the fresh pagination suggestion duplicates the explicitly deferred #4955 follow-up. Receiving-account registration invalidates scan generations, preserves deeper checkpoints, and uses outgoing requests' Platform-assigned heights, while the corrected guard tests now exercise reconciliation without pre-sweep deferral. Independent offline library testing passed all 1,179 platform-wallet tests and 16 platform-encryption tests, and git diff --check passed; live SPV behavior was not exercised.

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.
- Expose sent-history exhaustion through the SDK query result — The SDK still returns the same successful document collection after exhaustion and after 50 full pages, while ingest_sent_sweep marks discovery complete after successful fetching and persistence. Restored contacts outside that first batch can therefore be reconciled before their earliest publication is known. This is a concrete remaining limitation explicitly excluded from this PR and tracked in #4955, not a separate new finding.
- Follow-up: Continue #4955 by exposing exhaustion and continuation information from the SDK, preserving bounded fetching, and completing initial sent-history discovery only after exhaustion and successful ingestion.
- Provide atomic checkpoint rewind and scan-generation invalidation upstream — At the pinned rust-dashcore revision, update_synced_height does not change account_generation, and filter-batch commits check generation and contiguity. Reconciliation can consequently lose a rewind within an already-scanned batch's range. New receiving-account registration correctly invalidates generation; the separate, pre-existing reconciliation race remains explicitly tracked in #4955.
- Follow-up: Continue #4955 with an upstream key-wallet rewind-and-invalidate API, consume it from reconciliation, and cover a batch scanned before the rewind but committed afterward.

A DashPay payment is missed when the wallet scanned its block before it learned about the contact request. On
v4.3-dev, contact accounts are inserted without telling the SPV scanner that the watched address set changed. Already-scanned blocks are never re-checked for the new addresses.reconcile_dashpay_rescanonly covered established (two-way) relationships.Scenario: Alice sends Bob a contact request from device A, and Bob pays her. Device B scans that block before it sees Alice's request, so the payment never shows up. Alice's outgoing request is enough for Bob to pay her, so reciprocal acceptance is not required, and the relationship may stay one-way.
