Why

Bug report: "I noticed a pretty terrible bug if you don't have internet. The wallet will not load (or you will see 0 balance)."

Reproduced from the code. Two independent app-side causes, neither needing an SDK or FFI change.

A. The balance was never published from local state. Its only producer is the SPV coordinator's balance bridge, and every caller ran after a successful startSpv. Offline that start is delayed by the DashPay readiness budget and can fail outright, so the published balance stayed nil and the home screen collapsed it to 0.00.

B. A Platform failure took Core down with it. refresh started Core SPV and Platform/BLAST inside one do/catch. A Platform throw ran fullReset, which stops SPV, clears wallet state and nils the host's modelContainer — the SwiftData handle the home transaction list reads. So the list emptied too, and nothing retried. That is the "wallet will not load" half.

What changed

  • Publish the persisted balance as soon as the host is bound, before any network work. host.start already runs loadFromPersistor, and coreWallet().balance() is a lock-free in-memory read — no SPV, no peers, no I/O. The home transaction list reloads off that same balance change, so it comes back with it.
  • Split the two starts. A Platform failure is contained in its own phase; the host, Core SPV, the balance and the SwiftData handles all stay up. currentNetwork is recorded before Platform is asked to start, so the degraded state is recognisable.
  • Refresh elision now reads Core readiness alone for the triggers that fire on their own (launch, foreground, the sync strip's Retry, "Sync Now"). They recover Platform in place instead of rebuilding a healthy Core. .networkDidChange keeps full readiness, because its callers detach the SPV subscriptions that only a rebuild re-attaches.
  • The network-switch verdict moves to Core readiness, so an offline switch no longer raises a blocking, Retry-only failure card over a runtime that works.
  • Reachability returning kicks the runtime, which brings a degraded Platform back on its own.

Two defects found on the same path and fixed here:

  • BalanceModel persisted userHasBalance = false for a not-yet-loaded balance. That value is per-wallet and feeds the default shortcut bar, so a single offline launch permanently dropped a shortcut from a funded wallet's bar. It now only writes when the balance is actually known.
  • The dead seedInitialBalance, whose doc comment claimed to be the balance's first producer, is gone.

The trigger routing is extracted to RuntimeRefreshPolicy so it can be tested without a live host, matching the existing PlatformSyncRearmPolicy.

No UI change

The red "Unable to connect" strip already appears on a cold offline launch — SyncingActivityMonitor's reachability gate forces .noConnection during its own init, before the home header reads it. Telling the user was never the missing piece. The missing piece was the number next to it, which read as an empty wallet.

Verification

Clean dashpay build. Accessibility audit reports no new findings. Unit-test target is still broken per CLAUDE.md, so the new table test is written compile-ready but unrun. Testnet smoke on iPhone 17:

Cause A — cold launch ordering. The balance is published 5.1 s before SPV starts, with SPV not yet running:

11:45:12.923  SPVCOORD :: first balance published total=10708219969 spv=false
11:45:15.994  DP-READY :: ready for SPV in 3.1s scans=0 drained=4
11:45:18.014  SPVCOORD :: started on 1

Previously the balance first appeared at that last line, and offline it never appeared at all.

Cause B — recovery without a Core teardown. Platform stopped from the Sync Info screen, then "Sync Now":

11:50:35.772  RUNTIME :: refreshing runtime for platformSyncRearm
11:50:35.772  RUNTIME :: refresh is already satisfied for 1
11:50:35.772  PLATFORM-ADDR :: starting for 1
11:50:38.735  PLATFORM-ADDR :: started for 1

No host stop/start, no SPV restart, no balance clearing. On develop this same path went through the full teardown and rebuild.

Now verified: a true no-network cold launch. Every uplink on the host was taken down — the first attempt only looked offline, because the Mac had silently failed over to a tethered iPhone on 172.20.10.x. With the machine genuinely cut off, the maintainer ran all of it end to end: cold launch shows the persisted balance and history immediately with the red "Unable to connect" strip; repeated Retry never blanks them; connectivity returning resumes sync on its own; and an offline network switch completes both ways.

startSpv succeeds with no network, which is what makes the fix hold on the reported path — PeerNetworkManager::new only opens the on-disk peer store, it does not resolve or connect. The offline logs show it:

08:45:59.838  SPVCOORD :: first balance published spv=false     (mainnet)
08:46:05.211  SPVCOORD :: started on 0
08:47:15.882  SPVCOORD :: first balance published spv=false     (testnet)
08:47:29.425  SPVCOORD :: started on 1

If Core start did throw, the catch runs fullReset and the balance goes back to nil — deliberately, because that path tears the host down and a balance published from a dead runtime would be state with nothing behind it.

Review notes

  • currentNetwork now means "Core is bound", not "everything is up". It is private and read only through the two predicates.
  • An offline network switch now reports success with Platform degraded. The Sync Info screen's lastError is the surface that says so. Worth confirming that is the intended product behaviour.
  • The elided .startIfReady branch now awaits a BLAST start instead of returning immediately. Bounded by the isRunning guard, and offline each attempt is a fast throw.

Out of scope, deliberately: distinguishing "unknown" from zero in the balance UI, a "last updated" timestamp, and a reachability gate on discoverIdentities (which offline can park an uncancellable thread for ~200 s). Happy to follow up on any of them.

… outage from wiping Core

Without a network the home screen showed 0.00 and an empty transaction
list. Two independent causes, both app-side.

The published balance had a single producer, the SPV coordinator's
balance bridge, and every caller ran after a successful startSpv.
Offline that start is delayed by the DashPay readiness budget and can
fail outright, so the balance stayed nil for the session and the home
screen collapsed it to zero. The bridge only needs the host's bound
wallet: host.start already runs loadFromPersistor, and the core wallet's
balance is an in-memory read with no SPV, no peers and no I/O. Publish
it as soon as the host returns, before any network work. The home
transaction list reloads off that same balance change, so it comes back
with it.

The runtime also started Core SPV and Platform in one do/catch, so a
Platform throw ran fullReset: SPV stopped, wallet state cleared, and the
host's modelContainer nilled, which is the SwiftData handle the
transaction list reads. Split the two starts, record currentNetwork
before Platform is asked to start, and keep a Platform failure contained
in its own phase. Refresh elision now reads Core readiness alone for the
triggers that fire on their own, so a launch, a foreground kick, the
sync strip's Retry and "Sync Now" recover Platform in place instead of
rebuilding a healthy Core. The network-switch verdict moves to Core
readiness for the same reason, so an offline switch no longer raises a
blocking failure card over a working wallet. Reachability returning now
kicks the runtime, which brings a degraded Platform back on its own.

Two defects on the same path: BalanceModel persisted userHasBalance =
false for a not-yet-loaded balance, which permanently dropped a shortcut
from a funded wallet's bar after one offline launch; and the dead
seedInitialBalance, whose doc comment claimed to be the balance's first
producer, is gone.

The trigger routing is extracted to RuntimeRefreshPolicy so it can be
tested without a live host, matching PlatformSyncRearmPolicy.

Verified: clean dashpay build, accessibility audit reports no new
findings.

A "my wallet shows 0" report is answered by whether this line appeared,
what total it carried, and whether SPV was running at the time. Sits
next to the existing HOST stage and SPVCOORD start lines, and fires once
per session because it is guarded on the published balance still being
nil.

📝 Walkthrough

Walkthrough

The runtime now separates Core and Platform readiness, handles Platform startup failures independently, and retries Platform startup without rebuilding Core. Wallet startup publishes balance data earlier. Reachability starts the runtime only on transitions to online, and unknown balances do not overwrite persisted state.

Changes

Runtime and wallet state

Layer / File(s) Summary
Readiness policy and Platform state
DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKWalletRuntime.swift, DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKSPVCoordinator.swift
The runtime uses trigger-specific rebuild policies and separate Core and full-readiness checks. Core readiness uses the actual SPV client state and subscription state.
Refresh and Platform recovery
DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKWalletRuntime.swift, DashWalletTests/SwiftDashSDKCoreLifecycleTests.swift
Core and Platform startup use separate failure handling. Platform recovery can run without rebuilding Core. Tests cover refresh-elision rules and detached subscriptions.
Initial balance publication
DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKSPVCoordinator.swift, DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKWalletState.swift, DashWallet/Sources/UI/Home/Views/Home Balance View/BalanceModel.swift, DashWalletTests/PassiveWalletStateUITailTests.swift
Startup publishes persisted balance before network work. Wallet state uses a shared publication path. Unknown balances do not overwrite userHasBalance.
Reachability transition trigger
DashWallet/Sources/Application/Syncyng Activity Monitor/SyncingActivityMonitor.swift
The runtime starts only when network status changes to .online while the wallet lifecycle is idle.
Manager subscription state
DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKSPVCoordinator.swift
The coordinator records when manager subscriptions are detached and clears the flag after re-subscription.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to f6c79

The new immediate balance-publication path can crash the app when a main-thread callback is not MainActor-isolated. This should be made isolation-safe before merge.

Final validation — Phase 2 only (queue backlog)

The offline-balance and Core/Platform separation changes address the reported startup problems, but the new refresh policy can leave a running wallet with detached balance and sync subscriptions during queued recovery. The startup diagnostic also exposes the exact Core balance through public logging. Both findings are confirmed by source and base-to-head inspection; app build and runtime validation were not independently repeated.

Review provenance

In `DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKWalletRuntime.swift`:
- [BLOCKING] DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKWalletRuntime.swift:91-94: Do not elide a network switch after its subscriptions were detached
  When Core is running but BLAST is stopped, `switchNetwork(to:)` admits a same-network recovery and calls `prepareForNetworkSwitch()` before its refresh reaches the lifecycle queue. That preparation cancels the SPV progress, peer, and balance subscriptions and clears wallet state without changing Core's running flag. If a `.startIfReady` request is queued ahead of the switch refresh, this new policy lets it skip the Core rebuild and successfully restart only BLAST. The subsequent `.networkDidChange` then sees full readiness and also skips rebuilding, leaving the subscriptions detached and the balance cleared or stale. Later automatic refreshes continue to skip the repair. The base policy rebuilt Core for the earlier request while BLAST was down, restoring those subscriptions. Track pending subscription reattachment independently of service readiness, or make prepared network-change requests non-elidable, and add a lifecycle regression test covering recovery queued before same-network switch preparation.

In `DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKSPVCoordinator.swift`:
- [SUGGESTION] DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKSPVCoordinator.swift:657: Redact the aggregate wallet balance in the startup log
  This new info-level message is compiled into release builds and explicitly marks the exact aggregate Core balance as public. Anyone receiving a unified-log or diagnostic capture containing this entry can read that balance without opening the wallet UI; the logging path does not consult balance-hiding preferences. This is a diagnostic-data confidentiality concern, not a remote funds-theft path. Preserve the first-publish event and SPV-running flag, but omit the balance or mark it private.

Comment thread DashWallet/Sources/Infrastructure/SwiftDashSDK/SwiftDashSDKSPVCoordinator.swift Outdated
Conflict: `fullReset` gained `platformPhase = .notStarted` here and the
DashPay `clearStartupVerdicts()` call on develop. Both are needed; kept
both.

Review finding 1, blocking. `prepareForNetworkSwitch()` detaches the SPV
progress, peer and balance publishers and clears wallet state, but leaves
`runningNetwork` set. Core-only readiness therefore reported a usable
runtime while nothing was feeding it, so a refresh queued between that
preparation and the switch's own rebuild could elide the rebuild, and the
`.networkDidChange` behind it would then see full readiness and elide too
— leaving the subscriptions detached and the balance cleared with no
later refresh repairing it. The coordinator now tracks
`subscriptionsDetached`, set at the single detach site and cleared where
the publishers are re-attached, and `isCoreRuntimeReady` requires it to
be false. A regression test covers the window.

Review finding 2, suggestion. The startup balance log shipped the exact
aggregate balance as public, readable from any diagnostic capture without
unlocking the wallet. The amount is now `.private`; the event and the SPV
flag stay public, and those are what answer a "wallet shows 0" report.

Review findings addressed

Blocking — do not elide a network switch after its subscriptions were detached. Confirmed against the source. prepareForNetworkSwitch() calls detachManagerSubscriptions() and clearAllState() but never touches runningNetwork, so isRunning stayed true and the new Core-only readiness reported a usable runtime while nothing was feeding it. A refresh queued between that preparation and the switch's own rebuild could elide the rebuild, and the .networkDidChange behind it would then see full readiness and elide too, stranding the runtime with detached publishers and a cleared balance that no later refresh repaired.

The coordinator now tracks subscriptionsDetached, set at the single detach site and cleared where the publishers are re-attached, and isCoreRuntimeReady requires it to be false. isRuntimeReady composes that predicate, so the .networkDidChange path inherits the fix. testNoTriggerElidesWhileSwitchPreparationHasDetachedSubscriptions covers the window.

Suggestion — redact the aggregate balance in the startup log. Agreed, the amount is now privacy: .private. The first-publish event and the SPV-running flag stay public, and those are the two facts that actually answer a "wallet shows 0" report.

Also merged develop. The only conflict was in fullReset, where this branch adds platformPhase = .notStarted and develop added the DashPay clearStartupVerdicts() call. Both are needed and both are kept.

End-to-end testing

Every scenario below was executed end-to-end by the maintainer on a real offline machine, not simulated. Worth stating explicitly, because the first attempt looked like a pass and was not: the Mac had silently failed over to a tethered iPhone on 172.20.10.x, so the app never saw an offline path. The runs below were done with every uplink down.

scenario result
Cold launch, no connectivity Balance and transaction history render immediately, red "Unable to connect" strip shown
Retry on the strip, still offline Balance and history never blank
Connectivity returns Sync resumes on its own, no PIN re-entry, no relaunch
Network switch while offline, both directions Switch completes, overlay dismisses, no blocking failure card

Log evidence for the two that are easy to get wrong.

Five rapid Retry taps, every one elided, with no host teardown and no balance clear in between:

08:46:41.783  RUNTIME :: refreshing runtime for startIfReady
08:46:41.783  RUNTIME :: refresh is already satisfied for 0
08:46:42.009  RUNTIME :: refreshing runtime for startIfReady
08:46:42.009  RUNTIME :: refresh is already satisfied for 0
   … three more within the same second …

Balance published from local state before SPV starts, on both networks:

08:45:59.838  SPVCOORD :: first balance published total=<redacted> spv=false     (mainnet, empty wallet)
08:46:05.211  SPVCOORD :: started on 0
08:47:15.882  SPVCOORD :: first balance published total=<redacted> spv=false     (testnet, funded)
08:47:29.425  SPVCOORD :: started on 1

On develop that first line does not exist and the home screen sits on 0.00 with an empty list for the whole session.

Build and environment

Clean dashpay build against platform v4.2-dev @ 299d662c37 with a freshly rebuilt DashSDKFFI.xcframework. No public Swift SDK API was removed across that jump, and the SwiftData schema migration from V3 to V4 ran clean on an existing wallet database (HOST :: reusing persisted wallet; restored=1). Accessibility audit reports no new findings. The unit-test target remains broken per CLAUDE.md, so the new tests are written compile-ready but unrun.

One thing found, not fixed here

The offline network switch completes but takes about 41 s, of which 26 s is the native SDK destroy step; online the same step is 0–11 ms. It is not a regression from this PR, which does not touch the teardown path, so it is filed separately as #1120.

Reviewed at head 691bb0b0. The core of the change is sound and I could not fault it: splitting the Core and Platform starts into separate do/catch blocks, making refresh elision read Core readiness only, and publishing the persisted balance from loadFromPersistor before any network work all correctly address the "wallet shows 0 offline" report. The BalanceModel userHasBalance nil-guard is right — DWGlobalOptions.userHasBalance is per-wallet and reset on removal, so it cannot strand a stale true — and removing seedInitialBalance is safe, with no callers left in the tree.

One inline comment: the new reachability kick can leave the failed-network-switch card up over a healthy runtime, with Retry permanently dead.

The rest are non-blocking — recommendations, not requests. Merging without them is fine:

  • SwiftDashSDKWalletRuntime.swift:516 — the elided-refresh fast path now awaits startPlatformIfNotRunning(for:) while holding the serial lifecycleQueue, where it previously returned immediately. switchNetwork, switchWallet, performAddWallet and handleWalletWiped all await their own op on that same queue, so with Platform unreachable — the state this PR names .degradedPlatformAddressSyncCoordinator.startAsync can burn DAPI connect and DNS timeouts across evonodes while a user tapping a network switch, a wallet switch, or "Create wallet" in onboarding waits on a spinner behind a refresh that had nothing to do. Together with the inline finding this becomes reachable from a background Wi‑Fi/cellular transition rather than only at launch. Kicking Platform off the queue (or not awaiting it) keeps the fast path fast.
  • SwiftDashSDKWalletRuntime.swift:581 — a degraded Platform has no automatic recovery, although the comment justifying the design names "a launch/foreground kick, the sync strip's Retry and 'Sync Now'" as the routes back. There is no foreground kick: startIfReady is called only from didFinishLaunching, SyncView's Retry, and the new reachability transition. So when startPlatform fails for a server-side reason while the device stays online — no reachability transition ever fires — the runtime stays .degraded for the rest of the session, and switchNetwork now reports success via isCoreRuntimeReady, so no failure card appears either. The only signal reaches the user through the Sync Info screen. Either add a foreground startIfReady, or surface .degraded on the home sync strip.
  • SwiftDashSDKWalletRuntime.swift:584platformPhase is effectively write-only and can report the wrong thing. Its doc says .degraded is what "the retry paths" act on, but startPlatformIfNotRunning consults blast.isRunning && blast.runningNetwork == network instead, and the field's only reader is logLabel in the NETSWITCH line at 324. Nothing reconciles it when BLAST changes state out of band: after Stop on PlatformSyncStatusScreen.swift:314 it stays .running(...), and after a guard-return in startPlatformIfNotRunning a stale .degraded survives a Platform that is actually up. A 🔀 NETSWITCH … platform=running(mainnet) line can therefore be false in a diagnostic export, which is the one thing the field exists for. Derive the label from the coordinator at log time, or drop the enum.
  • SwiftDashSDKSPVCoordinator.swift:675 — the "first balance published" marker is not once-per-session as its comment claims: the guard is SwiftDashSDKWalletState.shared.balance == nil, and clearBalance() / clearAllState() restore nil on every network switch, wallet switch and wipe (fullReset calls clearAllState unconditionally). A support engineer following the comment — "a 'my wallet shows 0' report is answered by whether this line appeared" — will find several in one capture and can attribute the zero to the wrong start. Either say "first publish after each bind", or gate on a per-start flag reset in performStart.

🤖 Reviewed with Claude Code

…ycle state machine

The connectivity-return kick fired `startIfReady()` unconditionally. After a
network switch that failed while offline, the transition state sits on
`.failedNetworkSwitch` with a blocking card whose only controls are Retry and
Switch Back, and the selected network was already written to the target. When
connectivity returned, the kick rebuilt the runtime on that target and it
succeeded, but nothing called `finish()`, so the card stayed up over a working
wallet. Retry then reached `switchNetwork`'s ready-runtime no-op, which returns
without touching the transition state, leaving the card undismissable.

The kick now runs only while the lifecycle phase is `.idle`. In every other
phase that state machine owns recovery, and the card's own Retry is the path
back.

Final validation — Phase 2 only (queue backlog)

Verified the supplied Phase-2 findings against head 691bb0b: both prior findings are fixed, and no remaining in-scope blocker was confirmed. One regression-test suggestion remains, with its location corrected to the current source. This verification used source inspection; build, test-harness, and runtime results reported by reviewers and the maintainer were not independently reproduced.

Source: reviewer 1: gpt-6-astra (agent: phase2-reviewer, role: general); reviewer 2: gpt-6-astra (agent: phase2-reviewer, role: security-auditor); final verifier: gpt-6-astra (agent: astra-verifier, role: final-verifier)

In `DashWalletTests/SwiftDashSDKCoreLifecycleTests.swift`:
- [SUGGESTION] DashWalletTests/SwiftDashSDKCoreLifecycleTests.swift:547-553: Exercise the readiness predicate in the detached-subscription test
  This test passes `isCoreReady: false` and `isFullyReady: false` directly to the routing policy, so it never exercises the connection between detached subscriptions and runtime readiness. Removing `!spv.subscriptionsDetached` from `isCoreRuntimeReady(for:)` would recreate the fixed defect without failing this test. Exercise the production readiness predicate through a testable seam: assert that a bound host with running SPV becomes unready when subscriptions detach and ready again after reattachment, then verify the refresh routing from those computed values.

`applyBalance` always hopped through `DispatchQueue.main.async`, so the startup
publication landed a runloop turn later. That turn is not free: the startup
bridge runs on the MainActor and the work that follows it can hold the actor
before reaching any suspension point — the DashPay readiness budget lookup on
the dashpay build, and on the non-DASHPAY build the CoinJoin recovery-gap
widening, which pre-generates addresses and has been measured at over three
seconds. The home screen would sit on 0.00 for exactly that long, which is the
symptom this publication was added to remove.

A caller already on the main queue now publishes synchronously; every other
caller marshals as before, so delivery is never later than it was. The
assignment, the two refreshes and the notification move into a single
main-actor `publishBalance`, so there is still one publication path rather than
two.

Measured over a 40 s run: no `balance bridge held the main thread` warnings, so
the inline path costs nothing on the 1 Hz tick.

The detached-subscription test passed `isCoreReady: false` straight into the
routing policy, so it documented the fix without guarding it: dropping
`subscriptionsDetached` from the readiness predicate would have restored the
defect with the test still green.

The readiness composition moves into `RuntimeReadinessPolicy`, alongside
`RuntimeRefreshPolicy` and following the same shape as `PlatformSyncRearmPolicy`.
`isCoreRuntimeReady` and `isRuntimeReady` become thin adapters that read the
singletons and delegate, so the logic has one home. The test now computes
readiness from the state `prepareForNetworkSwitch()` actually leaves behind —
host bound, SPV flagged running, publishers detached — feeds the result into the
routing policy, and asserts the runtime becomes ready again once the publishers
are re-attached.

Final validation — Phase 2 only (queue backlog)

Verified the Phase-2 findings against head 33ca493: all three prior findings are fixed, and no in-scope findings remain. A standalone Swift harness using the extracted production policies and regression-test assertions passed; removing the detached-subscription guard produced five assertion failures. Full application build and offline runtime behavior were not independently validated in this verification.

Re-reviewed at head 33ca493f. My previous inline is closed, and closed well: the reachability kick is now held back while a lifecycle transition is in flight, with a comment that states the whole failure chain. I also checked the new MainActor.assumeIsolated there is safe — the apply closure runs either synchronously on the main thread or via DispatchQueue.main.async, so it is always on the MainActor's executor and cannot trap.

Not approving yet: the three commits since my review brought changes I had not seen, and a fresh pass turns up three things worth fixing first. Two of them I verified directly rather than reporting on the strength of a read-through.

Also verified sound this pass: PlatformAddressSyncCoordinator.performStop does not touch Core SPV or the host, so startPlatformIfNotRunning on the elided branch really is Core-safe; subscriptionsDetached is correctly re-set on the performStop stop-throw path; the .networkDidChange full-readiness requirement does keep the prepare/rebuild window from eliding; seedInitialBalance removal is clean; the switchNetwork no-op-without-finish() hazard is not reachable through the other startIfReady callers; and observers of activeWalletDidChangeNotification all key off SwiftDashSDKHost.shared, which Core binds, so publishing before the Platform start strands nobody.

Non-blocking recommendations:

  • SyncingActivityMonitor.swift:556lastNetworkStatus is overwritten before the lifecycleIsIdle check, so an .offline → .online transition that lands during a lifecycle operation is consumed and discarded. Switch networks offline, Core comes up, Platform degrades, connectivity returns while the phase is .switchingNetwork: the transition is swallowed, and once finish() returns the phase to .idle no further .online transition ever arrives — the degraded Platform waits for the next launch or a manual Sync Now. Recording the status only on the branch that acts, or re-arming when the phase returns to .idle, closes it.
  • SyncingActivityMonitor.swift:561lastNetworkStatus starts at .unknown, so the first path report counts as a "reachability returned" transition and startIfReady() now fires on every cold launch as soon as NWPathMonitor answers — including during onboarding, where the phase is .idle and the new guard does not apply. refresh runs fullReset before its WalletEnvironment.hasSDKWallet guard, and onboarding's createOrImportWallet runs outside the serial lifecycle queue. I did not verify that interleaving myself, so I am flagging it rather than asserting it — but seeding lastNetworkStatus from the first report without acting on it (or requiring previous == .offline) removes the question entirely.
  • SwiftDashSDKWalletRuntime.swift:198platformPhase is still write-only: its doc says .degraded is what "the retry paths" act on, but startPlatformIfNotRunning consults PlatformAddressSyncCoordinator.isRunning/runningNetwork directly and the field's only reader is logLabel in the NETSWITCH line. Either drive the retry off it or reduce it to a log string.

This catch undoes the early balance publish, so the reported bug may still be unfixed in the exact scenario it was reported from.

The publish added at SwiftDashSDKSPVCoordinator.swift:261 is what puts the persisted balance on screen before any network work. But any Core-start throw lands here and runs fullReset, whose stopAsyncperformStop(clearBalance: true) and SwiftDashSDKWalletState.clearAllState() both put balance back to nil — and the home screen collapses to 0.00 again.

So the offline fix holds only when host.start and manager.startSpv(config:) both succeed with no network. If startSpv throws offline — peer or seed setup is the obvious candidate — this PR delivers nothing for "wallet shows 0 offline". The PR's own Verification section says a true no-network cold launch was never exercised, which is the one test that would settle it.

An airplane-mode cold launch before merge is worth more here than any amount of reading: it either confirms the fix or shows that the catch path needs to preserve the published balance.

You asked for the airplane-mode launch as the deciding evidence, and it has since been run — the PR's Verification section said otherwise and was stale; updated now. Every host uplink was taken down (the first attempt only looked offline: the Mac had failed over to a tethered iPhone on 172.20.10.x). With the machine genuinely cut off, cold launch showed the persisted balance and history immediately with the red strip, repeated Retry never blanked them, reconnect resumed on its own, and an offline network switch completed both ways. The reason the fix holds is that startSpv succeeds with no network — PeerNetworkManager::new only opens the on-disk peer store, it does not resolve or connect — and the offline logs show it: first balance published spv=false at 08:45:59.838 then started on 0 at 08:46:05.211, and the same pair on testnet at 08:47:15.882 / 08:47:29.425. No code change: if Core start does throw, the catch tears the host down, and publishing a balance from a dead runtime would be state with nothing behind it.

…dinator's flag

`isCoreRuntimeReady` was fed `SwiftDashSDKSPVCoordinator.isRunning`, which is
`runningNetwork != nil` — a Swift-side flag set when this coordinator starts a
client and cleared when it stops one. A client that dies inside the SDK never
clears it, so a dead Core read as permanently ready. Narrowing elision to Core
readiness then removed the last in-session way back: launch, the sync strip's
Retry, "Sync Now" and the connectivity-return kick would all elide the rebuild
that would have revived it. Before this PR those triggers required full
readiness, so a co-occurring Platform outage still forced the rebuild.

Readiness now asks the SDK through a new `isSPVClientRunning`, which resolves
the manager from the host and calls `isSpvRunning()` — the same question
`isAlreadyRunning(manager:network:)` already asked of a manager the caller
holds. Verified at runtime that a healthy start still elides: `SPVCOORD ::
started on 0` followed by `refresh is already satisfied for 0` on the next
trigger, with no rebuild.

Also corrects `clearBalance()`'s doc, which claimed the wallet wiper was its
caller. Its two callers are the Core SPV stop and the balance bridge finding no
bound wallet; the wipe path resets per-wallet options through
`DWGlobalOptions.restoreToDefaults()` in the wiper. That stale comment is what
made the `userHasBalance` guard look like it had swallowed the wipe reset.

`PassiveWalletStateUITailTests` asserted that a cleared balance writes
`userHasBalance = false`. That was the behaviour the guard deliberately removed:
`nil` means "not known yet", never "empty", and the old write let one offline
launch permanently drop a shortcut from a funded wallet's bar. The assertion now
states the intended contract and says which path legitimately resets the flag.

…sh entry

`applyBalance` branched on `Thread.isMainThread` to justify
`MainActor.assumeIsolated` and publish synchronously. Being on the main thread
is a proxy for MainActor isolation, not a proof of it, so that branch could in
principle trap on a main-thread callback that is not running on the MainActor's
executor.

The proxy is gone rather than defended. `applyBalanceOnMainActor(_:)` is
`@MainActor`, so the compiler checks isolation at the one call site that needs
the synchronous publish — the coordinator's balance bridge, itself `@MainActor`.
`applyBalance` goes back to always marshalling for the SDK's `onBalanceUpdated`
callback, which arrives on a Rust-owned thread. Both still funnel through the
single `publishBalance`.

Doc comments naming the old method updated with it.

Final validation — Phase 2 only (queue backlog)

Verified the Phase-2 finding and all three prior findings against head bdc9364. The prior findings are fixed, but the new reachability recovery still has a scheduling window that can leave the network-switch failure overlay displayed over a recovered runtime with a nonfunctional Retry button. This verification used source and base-to-head diff inspection; the reviewer-reported build, harness, and runtime checks were not independently rerun.

In `DashWallet/Sources/Application/Syncyng Activity Monitor/SyncingActivityMonitor.swift`:
- [BLOCKING] DashWallet/Sources/Application/Syncyng Activity Monitor/SyncingActivityMonitor.swift:558-562: Recheck transition ownership when the queued reachability recovery executes
  The callback-time idle guard fixes connectivity returning while a failure card is already visible, but it does not protect the queued recovery. `startIfReady()` passes through `entryQueue` and a MainActor task before joining the lifecycle queue, whereas `switchNetwork(to:)` joins that queue directly. An online callback can therefore observe `.idle`, then have its refresh queued behind a newly admitted network switch. If that switch's Core start fails and the automatic refresh subsequently brings Core and Platform up successfully, the refresh leaves `.failedNetworkSwitch` unchanged. The overlay's Retry calls `switchNetwork(to:)`, which now returns through its ready-runtime no-op at lines 312–315 without calling `finish()`, leaving the card displayed on every retry. Give automatic reachability recovery a distinct trigger or entry point and recheck transition ownership inside its serialized operation before refreshing. Add a regression test for a kick admitted while idle but executed after a failed switch.
