…etry Persistence failures on the wallet rehydration and registration paths were flattened into `PlatformWalletError::WalletCreation(String)`, destroying the transient/fatal classification callers need and severing the `#[source]` chain. Adds typed `PersisterLoad` / `PersisterStore` / `PersisterRestore` variants carrying the `PersistenceError` (boxed for the recursive restore case) and routes every persister boundary through them. On top of that, `retry_transient` (4 attempts, 20 -> 200 ms doubling backoff) now wraps persister `store` / `flush` / `load` on the registration, startup and identity-discovery paths, so a transient `SQLITE_BUSY` no longer aborts wallet registration outright or costs the identity-scan verdict its durability (#4365). Fatal errors still fail fast. The retry re-drives a failed `store` via a bare `flush`, which `PlatformWalletPersistence::store` now documents as a backend contract. Also fixes the persister leak behind #4133: a failed `load_from_persistor` left the wallet-event adapter holding an `Arc<P>` clone, so re-opening the same path returned a spurious `AlreadyOpen` masking the real error. `load_from_persistor` now shuts the manager down on both failure paths, with a `Drop` backstop cancelling and aborting the adapter task. `record_or_persister_or_log` and `reconcile_sent_payments` stop swallowing permanent read failures as "not found": transient errors still defer to the next sweep, permanent ones propagate as `PersisterLoad` instead of stalling an unbounded poll loop with no explanation. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub>
`From<PersistenceError>` flattened every persistence failure into the generic `ErrorWalletOperation` (6), so hosts lost the transient/fatal classification the wallet layer now preserves. Adds `ErrorPersisterFatal = 49` and `ErrorPersisterTransient = 50`, claimed from the registry's allocation frontier, and de-flattens the conversion: `PersisterLoad` / `PersisterStore` map on `is_transient()`, `PersisterRestore` unwraps to its typed inner error. Ships the full three-layer parity the registry mandates — Rust enum with a discriminant pin test, `ERROR_CODE_REGISTRY.md` rows 47-50 with the frontier moved to 51, the Swift `PlatformWalletResultCode` / `PlatformWalletError` mirrors, and Swift raw-value pins. The variants are declared in ascending discriminant order (49 then 50), the order both enums otherwise keep; the comment records why 50 is not 48. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub>
…counts Contact-account registration went through `accounts.insert_funds_bearing_account`, which does not bump the wallet's `account_generation`. The running filter scan therefore never picked up the new account's addresses — a contact's incoming payments stayed invisible until something else happened to invalidate the scan. Registration now goes through `ManagedAccountOperations::add_managed_account`, and `PlatformWalletInfo` forwards `account_generation()` to the core wallet so the invalidation is observable. Tests assert generation `1` after registering both a contact and an external account. `reconcile_dashpay_rescan` no longer bails on `synced_height == 0`. A zero checkpoint already means "scan from genesis", but bailing left candidates unmarked, so once that scan advanced the very same contacts triggered a redundant funding-height rewind. Candidates are now marked as covered and the height is left alone. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub>
…ndex `broadcaster.rs` deleted its hardcoded 30 s `SPV_ACCEPTANCE_TIMEOUT` and now passes `None` to `broadcast_and_wait`. The local override was shorter than dash-spv's own budget, so sends were reported `MaybeSent`/uncertain while the SPV layer was still legitimately waiting. `SendTransactionView` non-platform -> platform flows use `senderAccountIndex = 0` instead of "first key-class-0 account with a positive balance": that search returned a key-class Platform-Payment account index, which was then fed to `CoreTransactionBuilder.setFunding(accountType: .bip44, ...)` — a different namespace, so core -> core sends could draw on the wrong funding account. Also in this batch: `run_tests.sh` tolerates a CI runner with no user default keychain under `set -euo pipefail`; `now_secs()` moves to `util.rs` as `pub(crate)`; the shield-input-selection regression test re-seeds off `reserve()` rather than hardcoded balances so it survives fee-schedule changes; and doc comments are corrected (`Wallet::new_watch_only` -> `new_external_signable`, `derive_spent_utxos` defaults, restore-loop skip behaviour). <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub>
The FFI restore path carried its own copy of the provider-key account reconstruction, which had already drifted from the SQLite backend's. Both now call `platform_wallet::changeset::rebuild_provider_key_account`, so FFI and SQLite restore provider accounts identically (-54/+30). Ordering: `rebuild_provider_key_account` ships with the wallet-storage PR's required bucket (`changeset/changeset.rs` + `changeset/mod.rs`). Until that lands on the base branch this commit does not compile — the sole error is the unresolved import. Land the storage PR first. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub>
…let-ffi-persister-codes-and-fixes Base carries the squashed forms of this branch's prerequisites (#4586 typed persister errors, #3968 storage backend, #4481 SPV timeout), so the pre-squash copies on this branch resolve to the merged versions: - 16afd79 (pre-squash #4586): error.rs, manager/{load,mod,startup, wallet_lifecycle}.rs, asset_lock/sync/proof.rs, identity/network/ {discovery,payments}.rs and changeset/traits.rs take the base. The branch's "store Transient MUST buffer" doc contradicted the base's store_transient_is_reissuable contract and is dropped. - f93aa3f (codes 49/50): superseded by the base's six-code 49-54 persister block (49 = LoadTransient, not Fatal). FFI error.rs, the registry and Swift PlatformWalletResult take the base; the stale Swift 49/50 test is removed, the code-26 raw-value pin is kept. - 40e04c2 (FFI provider-rebuild dedup): rebuild_provider_key_account landed as pub(super) in platform-wallet-storage, not in platform_wallet::changeset, and the FFI crate does not depend on the storage crate, so the import cannot resolve. FFI persistence.rs keeps the base's inline rebuild; dedup needs a follow-up relocation. Kept from this branch: contact-account add_managed_account generation fix and reconcile_dashpay_rescan zero-height change, reserve-derived shield regression fixture, now_secs dedup, doc and Swift cleanups.

…e merge The v4.2-dev merge took the base's permanent-read-failure sweep in reconcile_sent_payments, whose catch-all `Err(e)` records the failure and continues.

… storage and ffi
Provider key-material accounts (BLS ProviderOperatorKeys / EdDSA
ProviderPlatformKeys) were rebuilt by two copies of the same logic: a
pub(super) helper private to platform-wallet-storage's sqlite module and
an inline copy in platform-wallet-ffi's build_wallet_start_state. The FFI
crate does not depend on the storage crate, so the canonical helper now
lives in platform-wallet (a dependency of both) as
platform_wallet::changeset::provider_key_account::{
rebuild_provider_key_account, ProviderAccountRebuildError}, gated on the
bls/eddsa features that make its variants exist.
No behavior change:
- storage keeps its Invalid -> AccountRecordInvalid and
Rejected -> ProviderKeyAccountEntryMismatch mapping;
- ffi keeps its bincode decode (and the unmaintained-bincode-decoder
note), and maps helper errors to byte-identical Fatal
PersistenceError::backend messages.
Characterization tests pin both call sites before the move:
build_wallet restoring/rejecting provider manifest entries (storage) and
build_wallet_start_state restoring both provider accounts from
bincode-encoded specs (ffi). The helper's own unit tests move with it.

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.

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.

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.

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.

Issue being fixed or feature implemented
TL;DR: Make payments to newly discovered DashPay contact addresses appear even when the wallet has already scanned the blocks containing them. Rescan from the contact request's Core height when it is known; use the wallet's birth boundary when the original height cannot be determined safely.
User story
As a DashPay user restoring a wallet or using another device, I want to see payments from my contacts without having to start a manual full rescan.
Scenario
Alice sends Bob a contact request from device A. Bob pays her, and the payment is mined. Device B scans that block before learning about Alice's request, so it does not yet know the receiving addresses and misses the payment.
Learning the request must both add those addresses to the scanner and revisit the relevant blocks. Updating the address filter alone does not recover an already-mined payment. Alice's outgoing request already lets Bob pay her; reciprocal acceptance is not required.
What was done?
Detailed discussion
Builds on the refactor in #4587, which is merged. This PR targets
