feat(wallet): stage C — off-main runtime bootstrap (SDK build + loadFromPersistor) with stall telemetry - #1071
Merged

Conversation
…n the lifecycle queue Etap B of the Add Wallet freeze fix (a PARTIAL fix - see scope note below). Adopts the SDK's new async createWallet(mnemonic:) overload (platform feat/swift-sdk-async-create-wallet) so the blocking native create - both networks' key derivation + persistence flush, the bulk of the ~5s MainActor freeze - runs on the SDK's dedicated queue instead of the main thread. The overlay's spinner now animates through the create windows. - MnemonicFirstWalletCreation.run takes an async createWallet closure (single version - no sync/async pair); rollback-after-await semantics unchanged and now covered by a suspension-path test. - createAndPersist is async; its three call sites await it. The loadFromPersistor recovery path (recoverPersistedWallet) deliberately stays on the sync SDK overload. - SerialAsyncLifecycleQueue gains a value-returning enqueueAwaitable<T> (same chain, full barrier semantics), and the runtime gains performAddWallet: the interactive add now runs as ONE link of the serial lifecycle chain, so a queued refresh/fullReset can no longer interleave with the multi-network provisioning. The post-add switch stays OUTSIDE the chain (sequential op - nesting would self-await- deadlock the queue). Onboarding's createOrImportWallet deliberately stays off the chain (its launch-time race-by-design is unchanged). - The 100ms overlay-commit sleep STAYS: on the mirror-repair path the first provisioning work is still the other network's synchronous SDK build on the MainActor with no suspension point before it. Scope note: the mirror-network leg's SDK(network:) + configure + loadFromPersistor (~1.6-2s) still blocks the MainActor under the visible overlay - known limitation, candidate for etap C after the new create telemetry (offMain + duration logs) is in.

Review follow-up (P1): adopting the async SDK create everywhere put a REAL suspension point in the middle of createOrImportWallet's transaction - between the mnemonic persist and the wallet rows appearing. During that window the MainActor could run a concurrently scheduled startIfReady/refresh, which would see the mnemonic (hasSDKWallet) with no wallet rows yet, build a competing runtime, and the two flows could overwrite each other's publish or leak a manager to the deinit fallback teardown. The old sync FFI blocked the MainActor exactly there, so the ordering was NOT unchanged as previously claimed. createAndPersist gains offMainCreate: the interactive add keeps the async overload (safe - performAddWallet serializes it on the lifecycle queue, so refreshes queue behind it), while the onboarding/migration path (createOrImportWallet) forces the SYNC SDK overload via an explicitly typed non-async closure - no suspension between persist and create, restoring the atomic critical section. Onboarding cannot go on the lifecycle queue instead: refresh awaits the key migrator, and the migrator calls createOrImportWallet - enqueueing would self-deadlock. Onboarding therefore still blocks main for the create's duration (as before this PR); its off-main adoption needs its own serialization design and stays out of this etap.

…p telemetry Etap C groundwork: stage 1 (SDK init) has had a DWLogger timing since the network-switch fix, but stages 2 (ModelContainer), 3 (configure) and 4 (loadFromPersistor, both the detached-manager and launch paths) only had begin/end markers or nothing - so the ~3s main-thread gap in Add Wallet's mirror leg could not be attributed per stage. Each stage now logs its duration through DWLogger (rolling file -> Share application logs), plus a wall-clock total for the whole mirror preparation in addWallet. Deliberately NOT logged here: Thread.isMainThread after an await on this @mainactor type - it would always print true and prove nothing. The off-main flag appears only where it has evidential value (inside the build-queue block, added with the off-main SDK build commit). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Single-ping-pong runloop watchdog: a dedicated thread posts ONE block to the main queue and parks on a semaphore; the measured round-trip is the stall duration. The next ping goes out only after the previous one was answered plus a 100ms pause, so at most one ping is ever pending and a single long stall produces exactly one log line after it resolves - never a burst of queued-up reports. Latencies >=250ms (the Instruments microhang floor) log '⏱️ MAINSTALL ~Xms' through DWLogger, landing in the same rolling file as the bootstrap stage timings so stalls can be attributed to a stage by timestamp. This is the measuring instrument for the etap-C acceptance gate (no single stall >=500ms during Add Wallet). DEBUG-only; started from didFinishLaunching. The threshold classifier is a pure function pinned by a unit test (compile-ready; the app test target remains broken repo-wide). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Stage 1 of every runtime bootstrap - SDK(network:), one blocking dash_sdk_create_trusted FFI that assembles the tokio runtime, TLS stack and DapiClient, ~1-2s measured - ran on the MainActor. It was the single largest known main-thread block left in Add Wallet's mirror leg, and the same cost sat on launch, network switch, onboarding and wipe. makeRuntime is now async: stage 1 runs on a dedicated GCD queue (buildSDKOffMain - a plain queue, never Task.detached, because the blocking FFI would park a cooperative-pool thread) and hands the instance back at the suspension point. Safe because SDK is @unchecked Sendable, its init touches nothing main-bound, and after the continuation resumes the instance is only used from the MainActor; a thrown init constructs no object, and SDK.deinit releases the native handle if a later bootstrap stage throws. Stages 2-4 (ModelContainer, configure, loadFromPersistor) deliberately stay on the MainActor - their newly added timings decide whether they ever follow. The stage-1 timing now logs offMain= from inside the queue block, where the flag is actual evidence of where the work ran. Both callers (buildRuntime, managerForStoredWalletOperation) already were async; bootstraps stay serialized by the lifecycle queue, and the suspension sits outside onboarding's persist-to-create atomic section. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Measured gate passed: with the off-main SDK build, every add path's first provisioning work after the cheap duplicate guard is an await into off-main work (the async create, or the mirror leg's off-main SDK build), so the overlay window commits during that suspension. The stall monitor shows no >=250ms gap between 'add begin' and the first suspension in any of the three smoke runs (fresh create, import, already-exists - the last completing in 161ms total with no stall). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…trap Stage 4 was the measured culprit of the remaining Add Wallet stalls (~400ms per persisted wallet on the MainActor; 449-1436ms runloop stalls attributed by timestamp). Both bootstrap load sites now await the SDK's async overload (dashpay/platform: swift-sdk async loadFromPersistor), which runs the bulk restore and per-wallet lookups on the SDK's dedicated queue: - managerForStoredWalletOperation (the Add Wallet mirror leg / wipe) - verified: stage 4 in 406ms with NO runloop stall in the add window (previously a 449ms stall at the same wallet count); - loadPersistedWallet (launch/switch/refresh via start(), an async lifecycle-queue op) - kills the 834-1257ms stalls the switch path showed for the same restore. The SDK telemetry confirms the split: 'native load finished in 403ms offMain=true wallets=1' and 'load unlock loop finished in 2ms' - the marker-cached keychain unlock epilogue is negligible on the MainActor, so no further split of the load is warranted. recoverPersistedWallet (reinstall recovery, sync context) deliberately stays on the sync overload - same posture as in etap B.

One thing I would settle before this lands: the removal of the 100 ms overlay-commit sleep ( The new comment justifies it with "on EVERY add path the first provisioning work after the cheap duplicate guard is an await into off-main work". The await part is right; "cheap duplicate guard" is what I would push back on. This still runs on the MainActor before the first suspension point in let mnemonic = Mnemonic.normalizePhrase(mnemonic)
guard !mnemonic.isEmpty, Mnemonic.validate(mnemonic) else { ... }
let walletIds = try SwiftDashSDKStoredWalletNetworkResolver.walletIds(for: mnemonic)
let persistedWalletIds = Set(try WalletStorage().listWalletIdsWithMnemonic())
let networksToCreate = try Self.missingWalletNetworks(...)
The gate was "no >=250 ms gap between the add beginning and its first suspension", measured on the simulator. On device that stretch can be a large multiple of the measured number, and 250 ms is not much headroom. If it crosses the frame budget there, the overlay commits late again — the bug #1064 was opened to fix, returning in a form invisible to anyone testing on a simulator. The trade is also asymmetric: the sleep costs 100 ms once, on an operation that takes seconds and is already covered by a blocking overlay. Removing it saves a fraction of the visible time and risks reintroducing a fixed regression. Either take the same stall-monitor measurement on a real device (ideally not the newest one) and put the number in the PR, or keep the sleep until etap D and drop it once the pre-suspension stretch is itself off-main. |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Measure the main-queue completion time.
Line 71 reads the clock after the utility monitor thread resumes. If that thread is delayed after Line 68 signals the semaphore, latency includes worker scheduling time. A responsive main queue can then produce a false MAINSTALL log.
Record the completion time in the main-queue block before it signals. Pass that value safely back to the monitor thread for the latency calculation.

Retain the yield before performAddWallet.
ensureActive() schedules overlay presentation on a separate MainActor task. SwiftDashSDKHost.addWallet then performs synchronous wallet-ID derivation, keychain access, and network preparation before its first await. This work can delay the overlay’s first frame, even though manager.createWallet later runs off the main actor. The 250 ms monitor does not establish frame ordering. Retain the yield or move the pre-suspension work off the MainActor.

Issue being fixed or feature implemented
stage C of the Add Wallet performance work, stacked on #1068 (etap B). After etap B moved the create FFI off-main, a ~3s gap remained between the two creates: the mirror-network leg's temporary-manager bootstrap ran synchronously on the MainActor under the overlay — the spinner froze.
What was done?
Measure first, then fix what the measurements convict:
1. Telemetry (
3371f6c5b): stage 2 (ModelContainer), 3 (configure) and 4 (loadFromPersistor, both bootstrap sites) now log durations through DWLogger (→ Share application logs), plus a mirror-prep wall-clock total.Thread.isMainThreadis logged only where it has evidential value — inside the build-queue block — never after anawaiton a@MainActortype (where it would always print true).2. Main-thread stall monitor (
6ae3252aa, DEBUG-only): single-ping-pong watchdog — one pending ping max, a stall produces exactly one⏱️ MAINSTALL ~Xmsline after it resolves (no queued-ping bursts). Reports from 250ms (the Instruments microhang floor); the acceptance gate reads ≥500ms as a hang.3. Off-main SDK build (
0c14ce0ce):makeRuntimeis async; stage 1 (SDK(network:), one blockingdash_sdk_create_trustedFFI) runs on a dedicated GCD queue (neverTask.detached— the blocking FFI would park a cooperative-pool thread).SDKis@unchecked Sendable, its init touches nothing main-bound, and after the continuation resumes the instance is only used from the MainActor. Benefits every bootstrap path (launch, switch, onboarding, wipe, Add Wallet).4. Sleep removal (
1d75953bd): the 100ms overlay-commit sleep is gone — measured gate passed (no ≥250ms gap between "add begin" and the first suspension on any add path; the already-exists path completes in 161ms total with no stall).5. Async loadFromPersistor adoption (
7da299b18, needs dashpay/platform#4487): the measurements convicted stage 4 — ~400ms per persisted wallet on the MainActor (414/846/1261ms for 1/2/3 wallets; stalls 449–1436ms matching by timestamp), while stages 2–3 measured 0–9ms and the warm SDK build 0–5ms. Both bootstrap load sites (managerForStoredWalletOperation— the mirror leg and wipe;loadPersistedWallet— launch/switch/refresh viastart()) now await the SDK's off-main overload.recoverPersistedWallet(reinstall recovery, sync context) deliberately stays sync.Measured outcome (sim, testnet, stall monitor active)
native load finished in 403ms offMain=true,load unlock loop finished in 2ms(marker-cached unlock is negligible — no further split warranted).Regression smoke
Add Wallet fresh create / import / already-exists; wallet switch under its overlay; full wipe (Reset All) → onboarding create via both Show-Phrase and Skip; cold launch. Composite Creating → Switching → Home unchanged; no
deallocated without shutdownin logs; ordering create-current → prepare-mirror → create-mirror → shutdown-temp unchanged (lifecycle-queue serialization untouched).Build requirement: local
../platformon dashpay/platform#4487 (stacked on #4483). App test target remains broken repo-wide; the stall-monitor threshold classifier is pinned by a compile-ready unit test.🤖 Generated with Claude Code
Post-review verification (against dashpay/platform#4487 incl. its review-fix commit)
Rebuilt and re-smoked after the SDK-side hardening (unified sync/async native-op admission, handle-ownership fix, test isolation): fresh create, import, already-exists, wallet switch, two cold launches. All three Add Wallet windows show zero
MAINSTALL ≥250ms;native load finished … offMain=trueon every bootstrap; the app's twotry await loadFromPersistor()sites still resolve to the async overload (build green, no app changes needed).Follow-ups deliberately left out of etap C
SDKLifecyclestamp —dash_sdk_destroy finished in 0ms offMain=false. The destroy is trivially cheap on the MainActor, so no off-main hop is warranted; the stamp stays as a tripwire.createOrImportWallet): still deliberately synchronous (persist→create atomicity, etap B decision). The off-main SDK build lengthens the pre-existing suspension window before the atomic section; no regression observed in the wipe→onboarding smokes, but making onboarding off-main needs its own serialization design (etap D).ModelContainerbuild (~350–410ms on main, once per network per process) — under the 500ms gate; left as data.Summary by CodeRabbit
