…t did not establish Three defects on the bring-up path introduced or left open by #4359, all of which end the same way: `start_wallet_subsystems` returns a status that promises a contact's DIP-15 addresses exist before Core SPV starts, when they do not. An address the wallet is not watching when the compact-filter scan passes its funding height produces no transaction at all, so each of these is a silent data gap rather than a cosmetic mislabel. 1. A contact pass that reached nobody was recorded as a completed sync. `sync_contact_requests` is log-and-continue per identity — correct for the recurring sweep, and it collapsed "Platform answered, nothing new" into the same `Ok(vec![])` as "Platform answered nobody". With DAPI unreachable the sweep returned an empty success, startup called `record_sync_ran`, and `status()` reported `Ready`. The pass now reports what it reached. `sync_contact_requests_reporting` returns a `ContactSyncReport` carrying the per-identity failure set; `sync_contact_requests` keeps its shape and raises `ContactSyncUnreachable` when nothing at all was read. Startup records the sync only on a complete pass, so a degraded one stays `PartialAccountsPending`. Failures retry themselves: a failed fetch leaves that direction's high-water cursor unadvanced, so the next sweep re-requests exactly the range it missed. 2. A partial identity scan was never retried once any identity was on file. `ScanTally::is_trustworthy` is `identities_seen > 0 || failed_probes == 0`, so a scan that saw index 0 and got no answer at index 1 returns `Ok`; the warm-launch shortcut then skipped discovery on every later launch, and nothing recorded that the scan had been partial. The second identity, and all of its contacts, stayed invisible for the life of the installation. A scan now publishes a verdict — complete, or the indices it could not answer — which the shortcut consults. Two things follow: a partial scan is retried inside its own launch, with the scan key already resolved and within the budget the caller granted; and the verdict rides the changeset so a host that persists it re-opens the question on the next launch. Absence of a verdict deliberately reads as "unknown", not "incomplete", so hosts that have not adopted the field keep the shortcut instead of paying for a scan plus a Keychain round trip before every Core SPV start. The budget-expiry path records the same verdict, since a scan dropped mid-await never reaches its own bookkeeping. Refs #4365. Not closed: no persister vtable carries the field yet, so cross-launch retention still needs the host slot. 3. The seed-binding gate existed only in the Swift wrapper. Everything the drain does with key material is unauthenticated, and `register_contact_account` keys its existence check on `(index, us, them)` rather than on the xpub — so a provider resolving the wrong seed writes contact receiving addresses once, and every later correct-seed pass no-ops. The corruption is permanent and its only symptom is payments that never arrive. iOS gated this in Swift; a JNI binding added later would have inherited the ungated path. The shared sequence now verifies the binding itself, immediately before the drain and only when something is actually queued, so a warm launch with an empty queue still resolves no key material. It fails closed on any error — a provider that cannot answer has not been shown to own the wallet — and skipping costs nothing unrecoverable, because the queue is left intact for the next signer-present drain. Reported as the new `SeedBindingUnverified` status rather than raised, since Core sync must start regardless. Also fixes a latent misreport the rescan path exposed: the discovery-failure statuses claim the identity question is open, and a rescan can now reach them with an identity already on file. They are gated on `identity_id.is_none()`. 20 new tests, including three that drive the real `start_wallet_subsystems` over a mock SDK: a wrong-seed provider registers no contact account and leaves the queue intact, the owning seed drains, and an empty queue never consults the gate at all. The mock's failing fetches reproduce the DAPI-unreachable case for (1) end to end. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

⛔ Blockers found — Opus deferred (commit 2383632) |
…ardening Follow-up to bad2093 on this branch. Each of these is the same failure the original commit set out to fix, surviving on a path it did not cover. 1. The seed-binding gate still had an ungated entry point. The gate landed in `start_wallet_subsystems`, but `platform_wallet_drain_pending_contact_crypto` — the FFI the JNI binding calls — went straight to `drain_pending_contact_crypto` and `drain_auto_accepts` with no check at all. A JNI client draining with a wrong-seed resolver therefore wrote contact receiving accounts from the wrong seed, permanently: `register_contact_account` keys its existence check on `(index, us, them)` and not on the xpub, so no later correct-seed pass revisits them. That is the exact defect the commit message said was closed, still reachable from the entry point it named as the reason to close it. The gate moves into `PlatformWallet::drain_pending_contact_crypto_verified` — one primitive that verifies, then runs both drains — and the startup sequence and the FFI now both drain through it. Behaviour is unchanged on each: the check is still skipped when nothing is queued (a warm launch resolves no key material), still fails closed on every verification error and not only on a mismatch, and still leaves the queue intact. The FFI reports a refusal as `ErrorInvalidParameter` for `SeedMismatch` — the same code the standalone verify already returns, so a host recognises the wrong-seed condition identically however it arrives — and `ErrorWalletOperation` for a provider that simply could not answer. 2. A known-incomplete identity scan could still report `Ready`. `StartupTally` had no way to say "an identity is known and the set it belongs to is not". The discovery signals are gated on `identity_id.is_none()` (correctly — a rescan reaches them with an identity on file), so a launch whose rescan was forced by an incomplete verdict and then failed fell through every check to `Ready`: the status that promises the identity set is settled, on the one launch that knows it is not. `identity_scan_incomplete` is recorded from the verdict on record once discovery is done, and `status()` returns the new `IdentityScanIncomplete` rather than `Ready`. Reading the verdict rather than this call's discovery counters is what makes it correct on the launches that have no counters to read — a warm shortcut, or a rescan abandoned before it started — and it catches the same defect reached from the other side, a first scan that came back partial. The check is ranked last, so the only run whose status changes is the one that used to lie; every other run keeps a status clients already handle and reads the flag on the outcome. `discovery_worth_retrying` covers the new status: the unanswered indices are exactly what another scan could answer. The test that pinned this, `a_failed_rescan_does_not_reopen_a_settled_ identity`, asserted `Ready` for precisely the incomplete-rescan case. Its real subject — a failed rescan must not re-open an identity already on file — is preserved and now sits alongside an assertion that the scan gap IS reported, under a name that says so. 3. A local fault mid-scan published no verdict at all. `publish_scan_verdict` has one call site, below four `?` early returns in `discover_inner` (breadcrumb derivation, the wallet-info lookup, `add_identity`, `add_keys`). A persistence write that failed, or a wallet that left the manager, therefore abandoned the walk part-way through the index space and recorded nothing — and "unknown" is what keeps the warm-launch shortcut armed. Worse, when a previous scan had recorded a COMPLETE verdict, that stale verdict survived the abandoned scan. #4365's shape, on the local-fault path. The scan body now runs in a block whose result is carried out, so no `?` inside it can skip the publish — including any added later. The index the walk died on is recorded as unanswered first, because a verdict built from the probe bookkeeping alone would see an empty failed-index list and publish an abandoned scan as complete, which is strictly worse than publishing nothing. The abort index is tracked apart from `failed_indices` so `failed_probes` and `IdentityDiscoveryIncomplete` keep meaning "probes Platform never answered"; the verdict merges the two, since to a later launch they are the same fact. Note the scan loop is re-indented by one level and not otherwise touched — `git diff -w` shows the real change. The FFI outcome struct gains `identity_scan_incomplete` and the status enum appends `IdentityScanIncomplete = 6`; the Swift mirror follows both, as the `SeedBindingUnverified` append did. 11 new tests. The gate: a wrong-seed provider is refused with the typed error and registers zero contact accounts while the queue survives, the owning seed drains, an empty queue never consults the provider. The scan signal: both directions at the tally level, plus the wire-up driven through the real `start_wallet_subsystems`. The verdict: a real local fault injected mid-scan (a seedless wallet against the resident-key derive) replaces a stale complete verdict with an incomplete one, so the next launch re-scans.

tracking conflates remote fetch failures with local ingestion failures. Update

tracked separately, is_fully_degraded() only reflects identities whose remote

Deep line review from the release-triage side (head c968b30 vs current v4.2-dev — clean trial merge). The three headline fixes verified sound: retry loop bounded (3 attempts under the existing 20s budget), the drainable-count early-out is safe (auto-accepts share the same gated queue), Kotlin has no binding to the startup FFI so the new discriminants cannot crash hosts, Swift handles them with a conservative fallback, and the tests pin behavior with red-proof. Two blockers before merge, both small targeted fixes: B1 — The seed-binding gate misses the payment-path drain; a wrong-seed provider can still write permanent contact-account corruption
Failure scenario (the PR's own threat model — a mis-mapped Keychain/Keystore slot): user taps "send" to a contact while a It also falsifies the gate's own contract: Fix is small: route send_payment's pre-drain through Pre-existing path (not introduced by this PR), but this PR is the integrity-hardening change whose stated purpose and doc comment claim this class is closed. Confidence: high — call chain verified at all four layers. B2 — A persist failure still lets a degraded pass report

…ingest failure Follow-up to c968b30 on this branch. Both findings are, again, the same failure this change set out to fix, surviving on a path the last pass did not cover. 1. The seed-binding gate missed the payment path. `DashPayView::send_payment` opens by draining the deferred contact-crypto queue — before the write guard, before any funding input is signed — and did so UNVERIFIED. That drain runs the same `RegisterReceiving` / `RegisterExternal` ops the gate exists for, and it is reachable ungated from `platform_wallet_send_dashpay_payment`, from `ManagedPlatformWallet.sendDashPayPayment` (which builds a fresh `MnemonicResolver` and calls straight through) and from `Dashpay.sendPayment`. A mis-mapped Keychain/Keystore slot therefore derived the contact receiving xpub from the wrong seed and registered the account; `register_contact_account` keys its existence check on `(index, us, them)` rather than the xpub, so no later correct-seed pass revisits it. The payment then failed on the funding signatures — but the corruption was already written, and it is permanent. The third entry point to reach these ops with no gate, after the FFI drain and the iOS-only Swift check before it. It also falsified the gate's own contract: "a single place the gate can be removed from and none where it can be omitted" was not true while that call existed. The gated primitive moves down onto `DashPayView`, the handle the drain itself lives on, so there is no longer a way to reach the drain with a provider that has not been through the check. `PlatformWallet::drain_ pending_contact_crypto_verified` keeps its signature and its behaviour and now delegates: it early-outs on an empty queue exactly as before (both passes ride the same queue), calls the view primitive, and runs the DIP-15 auto-accept pass only after that has cleared the provider — so there is still no path to an auto-accept through an unverified provider. The startup sequence and the FFI drain entry point are untouched. The seed-binding check itself moves from `PlatformWallet` to `IdentityWallet` for the same reason (a `DashPayView` derefs to it); `PlatformWallet` keeps both public methods as delegates, so no caller changes. `send_payment` now fails with the typed `SeedMismatch` instead of draining. A payment through a wrong-seed provider could never have succeeded, so nothing that used to work stops working — what changes is that it fails BEFORE writing rather than after. `platform_wallet_send_dashpay_payment` maps that to `ErrorInvalidParameter`, the same code the standalone verify and the drain entry point already use, so a host recognises the wrong-seed condition identically however it arrives. No new result code. 2. A persist failure mid-ingest still reported a complete pass. The three ingest persist-failure branches in `sync_contact_requests_ reporting` set `received_persist_ok` / `sent_persist_ok = false` and `break`, correctly holding that direction's high-water cursor — but none of them marked the identity in the `ContactSyncReport`. The report stayed empty of failures, `is_complete()` returned true, startup's `Some(Ok(report)) if report.is_complete()` arm called `record_sync_ran()`, and the launch could reach `Ready` promising DIP-15 addresses that were never registered before Core SPV started. A held-back cursor and a report that says "complete" cannot both be right: the `break` abandons every remaining fetched request of that direction un-ingested, so their account builds were never enqueued. `ContactSyncReport` gains `unpersisted_identities` and `is_complete()` requires it empty. A separate bucket rather than reusing `failed_identities` because that list is what `is_fully_degraded()` reads to call an outage, and a local write failure on a pass Platform answered in full is not an outage — routing it there would make `sync_contact_requests` return `ContactSyncUnreachable` for a disk problem, telling a host to retry the network for a condition retrying the network cannot fix. That also addresses the review finding on this file asking for remote reachability and local ingestion to be told apart: the two local-state-loss branches (wallet gone, managed identity gone by the time the write guard was taken) move to the new bucket for the same reason, so `failed_identities` is now purely "the received fetch did not come back" and `is_fully_degraded()` is defined on remote reachability alone. The two ingest loops are lifted into `ingest_received_requests` / `ingest_sent_requests`, unchanged apart from returning the boolean rather than assigning it. That is what makes the persist-failure branches reachable in a test: the sweep itself cannot be driven far enough to exercise them without a Platform that answers document queries. 8 new tests. `cargo test -p platform-wallet --features shielded` is green (875, from 867), `cargo clippy` on platform-wallet and platform-wallet-ffi is clean with `--all-targets`, and `rs-unified-sdk-jni` still checks. Each new test was run against the unfixed code first. The wrong-seed payment test fails with `InvalidIdentityData("No DashpayExternalAccount found...")` — the drain having already run — and, with that assertion removed, on the account count: `left: 1, right: 0`, the wrong-seed account registered. The five report / ingest tests fail against `is_complete()` without the new bucket, against `is_fully_degraded()` counting it, and against ingest helpers that return success on a persist failure; the success-path controls pass throughout.

@shumkov — both blockers fixed in B1 — "The seed-binding gate misses the payment-path drain; a wrong-seed provider can still write permanent contact-account corruption"Confirmed at all four layers exactly as you described, and fixed. Rather than routing
Test: Red proof. Against the unfixed line ( — i.e. the drain had already run and the send failed later, on something else. Removing that first assertion to reach the next one: The wrong-seed account was in fact registered. Both pass with the fix. B2 — "A persist failure still lets a degraded pass report

Preliminary review — Codex only
The PR improves startup reporting and adds meaningful seed and persistence safeguards, but three in-scope integrity gaps remain: public unchecked drains bypass the new gate, a concurrency window can run auto-accept after verification was skipped, and failed contact writes are not actually retried before the cursor advances. One additional startup error path conservatively reports no identity even after discovery inserted one locally.

In `packages/rs-platform-wallet/src/wallet/identity/network/contact_requests.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/network/contact_requests.rs:2086-2104: Raw public drain APIs still bypass the seed-binding gate
`DashPayView` is publicly exported, and its unchecked `drain_pending_contact_crypto`, `drain_pending_contact_crypto_until`, `drain_auto_accepts`, and `drain_auto_accepts_until` methods remain public. An external Rust caller can therefore bypass the new verified wrappers and pass a provider for the wrong seed. The provider-only drain can permanently register contact accounts under the wrong xpub, while the auto-accept drain can derive the wrong proof key, classify a valid proof as permanently invalid, and clear it. This contradicts the new invariant documented in `seed_binding.rs` that every drain reaches one gate. Make the raw variants crate-private, move verification into the only public drain boundary, or require a verification-produced provider type that cannot be constructed without passing the seed check.
- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/network/contact_requests.rs:963-968: A failed contact persist is not retried on the next sweep
Returning `false` correctly makes the current report incomplete and keeps the cursor behind, but the state methods do not preserve a retryable in-memory state. `add_incoming_contact_request`, `apply_rotated_incoming_request`, and the fresh branch of `add_sent_contact_request` mutate the incoming, established, or sent maps before calling `persister.store`. If that write fails, the next sweep re-fetches the held-back range but sees the same request already present in memory, takes a same-reference dedup/no-op path, reports success, and advances the cursor. The backend never receives the failed write, yet a later startup can report a complete sync and `Ready`; after restart the contact state disappears. Persist before committing the mutation to memory, or roll the mutation back on failure, so retaining the cursor actually retries the write.
In `packages/rs-platform-wallet/src/wallet/identity/network/seed_binding.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/network/seed_binding.rs:255-267: Repeated queue probes can run auto-accept without verification
The outer wrapper first observes a nonempty queue, but the inner verified drain probes the queue again and returns `Ok(0)` without verification if another concurrent drain emptied it. After that unverified return, the outer wrapper still calls `drain_auto_accepts_until`. A recurring contact sweep can enqueue a new `AutoAccept` between those observations, causing the new entry to be processed with an unverified provider. With a wrong seed, the derived proof key fails verification and the valid proof is permanently marked failed and removed. Preserve whether the inner call actually verified the provider, and run the auto-accept pass only in the verified state; add a concurrency test covering nonempty → empty → newly enqueued auto-accept.
In `packages/rs-platform-wallet/src/manager/startup.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/manager/startup.rs:910-919: A local scan error ignores an identity already inserted incrementally
Discovery inserts sightings incrementally. For example, `add_identity` can insert index 0 before `managed.add_keys` returns a persistence error. This branch records only the local failure, leaving `tally.identity_id` unset, so startup skips contact synchronization and draining and returns an outcome with no identity even though the manager contains one. The timeout branch immediately above already handles the same partial-commit invariant by re-reading local state. Do the same for local errors; `StartupTally::status` will retain the local-failure signal without hiding the known identity.
…tact write retryable Follow-up to 63b69b2 on this branch. Both findings land ON that commit's fixes: each one closed its failure on the path it was looking at and left a neighbouring path holding the same assumption. 1. A queue probe was standing in for a verification. The whole-wallet wrapper probes the queue, delegates to the gated drain, then runs the DIP-15 auto-accept pass. The gated drain re-probes the queue and early-outs on empty WITHOUT verifying — correct on its own terms, since an empty queue derives nothing — but it returned `Ok(0)`, which the wrapper could not tell apart from a verified drain, and ran the auto-accept pass anyway. A concurrent drain emptying the queue between the two probes was enough: `drain_auto_accepts_until` re-snapshots the queue at its own instant, and the recurring contact sweep can enqueue an `AutoAccept` inside that window, so a brand-new entry was processed through a provider nobody had checked. The damage is not a failed pass. `drain_auto_accepts_until` verifies each proof against our re-derived auto-accept key and maps a mismatch to a PERMANENT verdict: the entry is cleared and marked so the sweep's enqueue gate will not re-offer it. A wrong seed re-derives the wrong key, so a perfectly valid proof is destroyed rather than deferred — the same "corruption survives the error" shape as the payment-path drain, one pass over. So verification is now carried, not inferred. Both gated primitives return a `ProviderBinding` recording whether the check actually ran, and the auto-accept pass moves behind its own gated primitive, `DashPayView::drain_auto_accepts_verified`, which takes that binding and runs the check itself whenever it is not already established. The binding is an optimisation, never the gate, and it cannot be forged — both constructors are private to `seed_binding`, so only a primitive that actually ran the check can mint one. There is deliberately no empty-queue early-out on the auto-accept side: the queue it would probe is re-snapshotted inside the drain anyway, so a probe there would only re-open the identical window. Net effect: no interleaving of the wrapper's two passes reaches an auto-accept through an unverified provider. The wrapper keeps its own empty-queue early-out, which still decides whether it does anything at all. 2. Holding the cursor did not actually retry the write. 63b69b2 made a persist failure hold that direction's high-water cursor and mark the identity `unpersisted`, so the pass reports incomplete and the launch stops claiming a sync it did not finish. Neither gets the write to disk: `add_incoming_contact_request`, `apply_rotated_incoming_request` and the fresh branch of `add_sent_contact_request` committed the mutation to memory BEFORE calling `persister.store`. On a failure the request stayed in `incoming_contact_requests` / `established_contacts` / `sent_contact_requests` regardless, and every retry gate reads those maps — the sweep's `tracked_reference == Some(reference)` skip, the no-op guards in `add_sent_contact_request`, the `already_applied` guard in `apply_rotated_incoming_request`. The re-fetched range therefore hit a same-reference dedup, reported success and advanced the cursor. The backend never received the write, a later startup called the sync complete and reached `Ready`, and the contact was gone after a restart. All three now persist before committing, the order `set_contact_metadata` and both rotation branches of `add_sent_contact_request` already used and documented — this extends that discipline to the branches it had not reached rather than introducing a new rule. The two auto-establish paths additionally read the opposite direction's entry with `get` instead of `remove`, so a failed store leaves both sides intact; consuming it first meant the retry could no longer reproduce the auto-establish and silently downgraded the pair to a bare one-directional request. 9 new tests. `cargo test -p platform-wallet` is green (804) and `--features shielded` is 973 passed / 1 failed, the failure being `shield_input_selection_tests::regression_reports_max_from_usable_suffix_not_ total_account_balance`, which fails identically on the untouched branch head and arrives from upstream v4.2-dev (no commit on this branch touches `platform_wallet.rs` except Hash's merge). `cargo clippy --all-targets` is clean on platform-wallet and platform-wallet-ffi, `rs-unified-sdk-jni` checks, and `cargo check --workspace --all-targets` passes. Every new test was run against the unfixed code first. Finding 1 — with the empty-queue early-out reporting a binding it had not established and the auto-accept pass ungated, the three gate tests fail and the controls pass: the auto-accept refusal returns `Ok(0)` where it must error ("an unverified provider must not reach the auto-accept pass: 0", i.e. the pass ran through the foreign provider), and both binding-reporting assertions fail. Finding 2 — with the three branches restored to commit-before-persist, all four retry tests fail. Relaxing their memory preconditions so they run on to the retry itself gives the exact defect: the SECOND sweep returns `true` (complete, cursor advances) while the store count is `left: 0, right: 1` — nothing reached the backend. The rotation test fails on memory sitting at the new reference (`left: 7, right: 0`), which is what trips both of its guards, and the auto-establish test on the outgoing request already consumed (`left: 0`).

Preliminary review — Codex only
The current head fixes the repeated-probe race, persist-before-mutation retry behavior, and CodeRabbit's contact-report taxonomy issue. One blocking integrity gap remains because the publicly exported DashPayView still exposes four unchecked drains; the local discovery-error path can also hide an incrementally inserted identity, and seed verification can exceed the startup deadline.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/network/contact_requests.rs:2086-2104: Raw public drain APIs still bypass the seed-binding gate
DashPayView is publicly re-exported, but drain_pending_contact_crypto, drain_pending_contact_crypto_until, drain_auto_accepts, and drain_auto_accepts_until remain public unchecked methods. A downstream Rust caller can therefore bypass the newly added verified boundaries and supply a provider for another wallet. The provider-only drain can permanently register contact accounts under the wrong xpub because account existence is keyed by the contact tuple rather than the xpub; the auto-accept drain can derive the wrong proof key, classify a valid proof as permanently invalid, and clear it. This directly contradicts seed_binding.rs's new invariant that every provider-deriving pass reaches the gate. Make the four implementation primitives crate-private and expose only boundaries that establish the seed binding.

Resolved in 89ea0dc — Seed verification runs outside the supplied drain deadline no longer present.
Auto-resolved by the review system based on the latest commit diff. If you believe this was closed in error, reopen the thread.
…adline
Both gated passes take a deadline, and the startup sequence hands one down
for one reason: no Platform-wallet step may hold Core SPV past its budget.
The check in front of them sat outside it. `establish_provider_binding`
awaited `ContactCryptoProvider::receiving_xpub` — a round trip into the
host's Keychain / Keystore — with no bound at all, so a host that never
answers held the whole launch for as long as it liked. An already-spent
deadline was worse than inert: it still paid for the mnemonic resolution
and the derivation before the drain it guards would have stopped at its
first entry.
The check now runs under the same deadline as the pass it gates. Bounding
it is safe in a way bounding the drains is not — that is why they have
`_until` variants instead of being wrapped in a timeout: they commit
per-entry side effects as they go, so dropping one mid-loop would strand
work that really happened. The check derives a public key and compares it,
committing nothing on the way, so an abandoned check strands nothing and
leaves the queue exactly as it found it. A deadline already spent refuses
without consulting the provider at all.
It fails closed onto the path already defined for a refused drain: the new
`SeedBindingUnanswered` lands on the same `Err` arm in the startup
sequence, which reports `SeedBindingUnverified` and starts Core SPV
anyway. It is deliberately its own variant rather than `SeedMismatch` —
that one is a *proven* wrong seed, and a check that never got an answer
proves nothing either way. Telling a host its Keychain slot is mis-mapped
when the truth is that its Keychain did not answer sends it after the
wrong fault. The shared refusal log stops claiming the stronger of the two
for the same reason.
5 tests. Red first: with the check restored to its unbounded form, exactly
the four gate tests fail and the control passes.
an_expired_deadline_refuses_the_gated_drain_without_consulting_the_provider
the refusal must say the check never got an answer, not claim a verdict
it never reached; got: SeedMismatch { .. }
an_expired_deadline_refuses_the_auto_accept_pass_without_consulting_the_provider
the refusal must say the check never got an answer; got: SeedMismatch { .. }
a_stalled_provider_cannot_hold_the_gated_drain_past_its_deadline
a provider that never answers must not hold the gated drain past its
deadline: Elapsed(())
a_stalled_provider_cannot_hold_the_auto_accept_pass_past_its_deadline
a provider that never answers must not hold the auto-accept pass
either: Elapsed(())
test result: FAILED. 18 passed; 4 failed
The two expired-deadline failures are the finding's second half verbatim —
the spent budget still bought a Keychain derivation, and the check ran on
to a verdict. The two stall failures are the first half: the call never
returned, so the cap the tests set well above their own deadline is what
ends them. `a_deadline_with_room_left_still_lets_the_owning_seed_through`
is the control, so none of the four can be satisfied by a gate that simply
refuses every bounded pass.
Also folded in: `cargo fmt` over the two files this branch already
touches. The formatting job is the branch's only failing check, and it
fails on three spots that predate this commit — `contact_requests.rs:4450`
and `seed_binding.rs:322`/`:1172`, all three flagged by CI's own rustfmt
on the current head. Nothing else in the workspace is affected.

Preliminary review — Codex only
The current head improves contact-sync reporting, retryable persistence, and deadline handling, but three in-scope integrity bypasses remain: unchecked public drains, a provider-agnostic binding token, and scan verdict replacement that can erase an unresolved identity gap. Two startup paths also remain inaccurate or unbounded in production: a local discovery error can hide an incrementally inserted identity, and the synchronous FFI mnemonic callback cannot be interrupted by the new Tokio timeout.

`ProviderBinding` contains only a copyable `Verified` state, while `drain_auto_accepts_verified` accepts an independent `&C`. Because both this method and `drain_pending_contact_crypto_verified_reporting` are public on the exported `DashPayView`, an external caller can obtain a verified binding with provider A and pass the inferred token to the auto-accept pass with provider B.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/network/seed_binding.rs:362-370: Seed verification runs outside the supplied drain deadline
(existing thread: https://github.com/dashpay/platform/pull/4426#discussion_r3869066365)
The new `tokio::time::timeout` bounds providers that yield, but it cannot interrupt the production FFI provider. `ResolverContactCryptoProvider::receiving_xpub` awaits `MnemonicResolverCoreSigner::extended_public_key`, whose async method synchronously executes `resolve_and_derive` and invokes the host vtable callback during one poll. Swift's `mnemonicResolverResolveTrampoline` then performs the Keychain read synchronously. If that callback blocks, the task cannot yield for Tokio to observe its timer, so the scoped startup thread and `platform_wallet_manager_start_wallet_subsystems` can still remain blocked beyond the caller's budget. The stalled-provider test uses `std::future::pending().await`, which yields and does not model this production path. The callback operation must become interruptible or run through an owned lifetime-safe worker mechanism; moving the current borrowed, pass-unretained handle into detached blocking work would create a use-after-free window after timeout.

`publish_scan_verdict` unconditionally replaces the previous verdict with the current scan's verdict, even though the default discovery options resume after the highest registered identity. For example, a scan that finds identities at indices 0 and 2 but gets no answer at index 1 correctly records index 1 as unresolved. A later default `sync()` or host discovery call resumes at index 3; if that suffix is answered cleanly, it publishes `complete` and erases the unresolved index 1 without probing it. Startup can then take the warm shortcut and report a settled identity set while the identity at index 1 and its contacts remain missing. Preserve unresolved indices until a scan actually covers and answers them, or only let a complete verdict supersede an incomplete one when its coverage includes every outstanding gap.
In `packages/rs-platform-wallet/src/manager/startup.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/manager/startup.rs:910-919: A local scan error ignores an identity already inserted incrementally
Discovery inserts an identity into `IdentityManager` before later fallible work. In particular, `add_keys` mutates the identity's in-memory key set before `persister.store` can return an error. This branch records only the local discovery failure, so on a fresh launch `tally.identity_id` remains unset even though the identity is resident. Startup then exits at the no-identity check without synchronizing contacts or draining queued work, and the outcome omits the known identity. Re-read local state here as the timeout branch already does while retaining the local-failure signal.

…ified `ProviderBinding` carried nothing but a copyable verdict, while `drain_auto_accepts_verified` took an independent `&C`. Both it and `drain_pending_contact_crypto_verified_reporting` are public on the exported `DashPayView`, so the pairing was the caller's to get wrong: verify with provider A, hand the binding to the auto-accept pass running provider B, and B skipped the check entirely. It then derived from the wrong seed, and `drain_auto_accepts_until` maps a proof that does not verify against the re-derived key to a PERMANENT verdict and clears it — so a valid auto-accept proof is destroyed and the sweep's enqueue gate never offers it again. The same hole is reachable across wallets: the two views have the same type, so a binding earned on wallet A was equally good on wallet B. The binding now borrows the provider it was checked against, and the pass takes the binding INSTEAD of a provider and derives through the one inside it. There is no second provider to name, so verify-with-A-drain-with-B stopped being expressible rather than stopping at a runtime check. The binding also records the wallet the check ran for, because nothing but the id can separate two views of the same type; a binding that does not match sends the pass back through the check rather than being trusted, the same fail-safe shape an unestablished binding already had. 1 test. Red first, against 89ea0dc with the provider argument this commit removes still passed in: a_binding_earned_elsewhere_cannot_authorize_this_wallets_auto_accepts a binding earned on another wallet proves nothing here: 0 test result: FAILED. 0 passed; 1 failed `Ok(0)` is the finding verbatim — wallet B's auto-accept pass ran through a binding earned on wallet A, having consulted nothing. Green after the fix, and the provider half of the same mispairing is now a compile error rather than a test. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`publish_scan_verdict` replaced whatever verdict was on record with the current scan's. Discovery's default options resume one past the highest registered identity, so a wallet with identities at 0 and 2 and no answer at index 1 correctly records index 1 as unresolved — and then a later `sync()` or host discovery call resumes at 3, answers everything from there cleanly, and publishes `complete`. Index 1 is erased without ever being probed, the next launch takes the warm shortcut, and startup reports a settled identity set while the identity at index 1 and all of its contacts stay missing. That is the Ready-without-integrity gap this bookkeeping exists to close, reached through the bookkeeping itself. A verdict now carries the coverage it is entitled to speak for — `probed_from` alongside `probed_through` — and is folded over the one already on record instead of replacing it. A recorded unanswered index survives unless this scan covered and answered it; `complete` requires both a clean scan and nothing carried over. A scan abandoned mid-await names no index at all, so nothing can carry its gap forward: only a scan starting at index 0 may clear that one, which is what the startup rescan already does. The fold lives in `IdentityManager::record_identity_scan`, the single path every writer takes — discovery, the startup cut-off recorder, and the changeset apply — rather than in each of them, and that method now returns what it stored so the persisted changeset is exactly what is in memory. `PlatformWalletChangeSet::merge` folds on the same rule for the same reason. 2 tests. Red first, against 89ea0dc with the pre-fix constructor arity: a_clean_suffix_scan_cannot_erase_an_unresolved_index a scan that never probed index 1 must not clear it test result: FAILED. 0 passed; 1 failed Both tests close with a scan that DOES cover the gap and assert the shortcut comes back, so neither can be satisfied by a verdict stuck on incomplete.

Preliminary review — Codex only
The provider-bound verification token and coverage-aware scan folding correctly resolve two prior blockers, and the current contact-sync report now separates remote reachability from local ingestion failure. One blocking integrity gap remains because the publicly exported DashPayView still exposes unchecked drain methods; two startup accuracy and deadline issues also remain as suggestions.

DashPayView is publicly re-exported, but drain_pending_contact_crypto and drain_pending_contact_crypto_until remain public unchecked methods here; drain_auto_accepts and drain_auto_accepts_until are likewise public at lines 2828-2846. A downstream Rust caller can therefore bypass every ProviderBinding-based boundary and supply a provider for another wallet. The provider-only drain can permanently register contact accounts under the wrong xpub because account existence is keyed by the contact tuple rather than the xpub. The auto-accept drain can derive the wrong proof key, classify a valid proof as permanently invalid, and clear it. This also contradicts seed_binding.rs's new assertion that there is no way to reach the drain without passing the gate. Make these four implementation primitives crate-private and leave only the verified boundaries public.

- [SUGGESTION] packages/rs-platform-wallet/src/manager/startup.rs:918-919: A local scan error ignores an identity already inserted incrementally
Identity discovery mutates local state before every remaining fallible operation completes. add_identity inserts the identity into IdentityManager, and add_keys installs its public keys in memory before persister.store can fail. When that persistence error reaches this branch on a fresh launch, the code records only discovery_failed_locally and leaves tally.identity_id unset. Startup then returns at the no-identity guard, skips contact synchronization and queued work, and reports no identity even though one is resident. Re-read local_identity_id here, as the timeout branch already does, while retaining the local-failure signal.

(existing thread: https://github.com/dashpay/platform/pull/4426#discussion_r3869066365)
tokio::time::timeout can enforce this deadline only when the wrapped future yields. The production ResolverContactCryptoProvider awaits MnemonicResolverCoreSigner::extended_public_key, but that async method synchronously calls resolve_and_derive and invokes the host resolver vtable during one poll. On iOS, mnemonicResolverResolveTrampoline synchronously calls WalletStorage.retrieveMnemonicUTF8Bytes, including SecItemCopyMatching. If that callback blocks, Tokio cannot poll the timer, so platform_wallet_manager_start_wallet_subsystems and its scoped startup thread can remain blocked beyond the caller's budget. The stalled-provider test uses std::future::pending(), which yields and therefore does not exercise this production behavior. Enforcing the deadline requires an interruptible callback or an owned, lifetime-safe worker design; detaching work that uses the current pass-unretained resolver handle would create a use-after-free window.

Preliminary review — Codex only
Two blocking integrity gaps remain: publicly accessible raw drain methods bypass the seed-binding gate, and scan-state folding can forget an earlier unlocated gap after an incomplete suffix scan. The local discovery-error outcome can still omit an identity already inserted in memory, and the production synchronous mnemonic callback cannot be interrupted by the Tokio deadline; CodeRabbit's contact-report taxonomy issue is fixed at this head.

- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/network/contact_requests.rs:2086-2104: Raw public drain APIs still bypass the seed-binding gate
`DashPayView` is publicly re-exported, but `drain_pending_contact_crypto`, `drain_pending_contact_crypto_until`, `drain_auto_accepts`, and `drain_auto_accepts_until` remain public and accept an unchecked provider. Downstream Rust callers can therefore bypass every `ProviderBinding` boundary and supply another wallet's provider. The provider-only drain can permanently register contact accounts under the wrong xpub because account existence is keyed by the contact tuple rather than the xpub; the auto-accept drain can derive the wrong proof key, classify a valid proof as permanently invalid, and clear it. Make all four raw implementation primitives crate-private so the verified methods are the only public drain boundaries.

- [BLOCKING] packages/rs-platform-wallet/src/changeset/changeset.rs:1355-1363: An incomplete suffix scan can discard an earlier unlocated gap
`previous_gap_is_unlocated` affects only this fold's `complete` bit and is not represented in the resulting state when the newer scan has named failures. For example, `incomplete(0, 0, [])` followed by an incomplete suffix scan produces a state containing only the suffix's `failed_indices`. A later clean suffix scan can cover those named indices, observe that the previous list is nonempty, and set `complete = true`, even though no scan beginning at index 0 ever superseded the original unlocated gap. Startup can then take the warm shortcut while a lower identity remains undiscovered. Preserve the unlocated-gap fact across every intermediate fold until a complete scan beginning at index 0 supersedes it, and add a regression for abandoned state → incomplete suffix → clean suffix.
In `packages/rs-platform-wallet/src/manager/startup.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/manager/startup.rs:910-919: A local scan error ignores an identity already inserted incrementally
Discovery mutates identity state before all remaining fallible work completes. `add_identity` inserts the identity into the manager, and `ManagedIdentity::add_keys` installs its public keys in memory before `persister.store` can fail. If that persistence error reaches this branch on a fresh launch, only the local-failure signal is recorded and `tally.identity_id` remains unset. Startup consequently exits at the no-identity guard, skips contact synchronization and queued work, and reports no identity even though one is resident. Re-read local identity state here, as the timeout branch already does, while retaining the local-failure signal.

🔴 Blocking: An incomplete suffix scan can discard an earlier unlocated gap
previous_gap_is_unlocated affects only this fold's complete bit and is not represented in the resulting state when the newer scan has named failures. For example, incomplete(0, 0, []) followed by an incomplete suffix scan produces a state containing only the suffix's failed_indices. A later clean suffix scan can cover those named indices, observe that the previous list is nonempty, and set complete = true, even though no scan beginning at index 0 ever superseded the original unlocated gap. Startup can then take the warm shortcut while a lower identity remains undiscovered. Preserve the unlocated-gap fact across every intermediate fold until a complete scan beginning at index 0 supersedes it, and add a regression for abandoned state → incomplete suffix → clean suffix.

Three defects on the wallet bring-up path, all of which end the same way:
start_wallet_subsystemsreturns a status that promises a contact's DIP-15 addresses exist before Core SPV starts, when they do not. An address the wallet is not watching when the compact-filter scan passes its funding height produces no transaction at all — so each of these is a silent data gap, not a cosmetic mislabel.Two come from the automated review of #4359 (findings F1 and F2); the third is the follow-through on a deferral #4368 took deliberately.
1. A contact pass that reached nobody was recorded as a completed sync (F1)
sync_contact_requestsis log-and-continue per identity — right for the recurring sweep, and it collapsed two opposite endings into one return value. "Platform answered, and there is nothing new" and "Platform answered nobody" both arrived asOk(vec![]). With DAPI unreachable every identity's fetch hit thecontinue, the sweep returned an empty success,startup.rscalledrecord_sync_ran, andstatus()reportedReady.Readyis precisely the claim that a contact pass completed, so this fed the persistence-corruption class the audit was tracking: SPV starts against an address set that is silently short.Fix. The pass now reports what it reached rather than only what it found:
sync_contact_requests_reportingreturns aContactSyncReportcarryingidentities_attempted, the identities nothing was ingested for, and the identities whose sent side alone failed.sync_contact_requestskeeps its shape and raisesContactSyncUnreachablewhen there were identities to read and not one was read.dashpay_sync_ran = false, sostatus()staysPartialAccountsPending.Partial passes keep sensible semantics: what was fetched is real and stays persisted, and the failures retry themselves — a failed fetch leaves that direction's high-water cursor unadvanced, so the next sweep re-requests exactly the range it missed. A partial pass is still not complete, because the identities it missed have contact requests nobody looked at and account builds nobody enqueued.
The recurring sweep at
dashpay_sync.rsalready logs-and-continues on anErrfrom this call, so the new error is a strict improvement there too: a total outage used to be recorded as a successful sweep.2. A partial identity scan was never retried once any identity was on file (F2 = #4365)
ScanTally::is_trustworthyisidentities_seen > 0 || failed_probes == 0, so a scan that saw index 0 and got no answer at index 1 returnsOk— correctly, since discarding what it found would be worse. Butstart_wallet_subsystemsskipped discovery whenever any identity was on file, and nothing recorded that the scan had been partial. There was no next scan. The second identity, and every contact hanging off it, stayed invisible for the life of the installation.Fix. A scan now publishes a verdict — complete, or the specific indices it could not answer — and the shortcut consults it. Two things follow:
PlatformWalletChangeSet::identity_scan_stateand restores throughIdentityManagerStartState::scan_states, so a host that persists it re-opens the question on the next launch.The budget-expiry path gets the same treatment, since a scan dropped mid-await never reaches its own bookkeeping — without it that path reproduces the bug in its own right, by consulting local state, finding the sighting persisted before cancellation, and recording a warm launch.
Absence of a verdict deliberately reads as "unknown", not "incomplete". Treating unknown as incomplete would make every launch on a non-adopting host pay for a full gap-limit scan plus a Keychain round trip before every Core SPV start — the cost the shortcut exists to avoid, and which review specifically asked to remove.
Refs #4365 rather than closing it: no persister vtable carries the field yet, so cross-launch retention still needs the host slot. See Residual limitations.
3. The seed-binding gate existed only in the Swift wrapper (#4368 follow-through)
Everything the drain does with key material is unauthenticated, and
register_contact_accountkeys its existence check on(index, us, them)— not on the xpub. A provider resolving the wrong seed therefore writes contact receiving addresses once, and every later correct-seed pass no-ops forever. The corruption is permanent and its only symptom is payments that never arrive.iOS enforces this in
PlatformWalletManagerStartup.swiftbefore it calls across. #4368 named the exposure and deferred it:Fix. The shared sequence verifies the binding itself, via the existing
PlatformWallet::verify_seed_binds, immediately before the signer-present drain. Three properties worth calling out:drainable_contact_crypto_count() > 0. With nothing queued the drain would derive nothing, so there is no wrong-seed write to prevent — and a warm launch still resolves no key material at all.WalletStartupStatus::SeedBindingUnverified(FFI discriminant 5, SwiftseedBindingUnverified), plusseed_binding_unverifiedon the outcome. Core sync must start regardless.The Swift check stays. The two are not redundant: Swift throws and refuses the call outright, which is the right behaviour on a host that can, while the Rust one fails closed and reports — it has to let Core SPV start.
Also fixed
A latent misreport the rescan path exposed.
DiscoveryFailedandPartialNoIdentityboth claim the identity question is still open. That used to be structurally guaranteed — discovery ran only when nothing was on file, and every branch that found something returned early — but a rescan forced by an incomplete prior scan reaches those branches with an identity already recorded. Both are now gated onidentity_id.is_none(), so a failed rescan no longer hides a sync and drain that both ran.Tests

pending_contact_crypto_addedalready carries. Within a process it redirects a second bring-up, and the in-launch retry closes the window whenever Platform recovers inside the budget. What remains open is a probe that fails for the entire budget and is never revisited after a restart. Adopting it needs an FFI vtable slot plus SwiftData/Room columns; the SQLite reference persister cannot demonstrate the round trip either, since itsload()still does not rehydrateClientStartState::wallets(WALLET_RESTOREis not attested).SeedBindingUnverifiedis a new enum variant in Rust, the FFI (discriminant 5) and Swift. Additive and appended, but a host matching exhaustively on the status will need the arm.🤖 Generated with Claude Code
