Lugano: needed, unblocks the required Run Tests check on approved PRs

Closes #1096

Description

• Fixes the wallet switch on the send review running its on-chain preparation twice. When the review reappears after the fee screens, iOS 26 and later start its .task(id:) twice for the same id, without cancelling the first run. The view now owns the switch run, keeps a live run for an unchanged context, and cancels it when the context changes or the view disappears.
• Fixes the intermittent testPendingWalletSwitchResumesAfterTags failure in CI. The mock suspended only the first preparation, so the resumed one finished at once and pushed .utxoSelection while the pop back from .tag was still animating. Each failure caught two or three routes visible at once. The mock now also holds the resumed preparation, so the test waits for the review to appear before letting it continue.

Neither failure comes from #799:

• Locally, its parent e7a21e8e fails the class the same way as master 35655ae8. It is one test, testCustomFeeWalletSwitchSurvivesFeeScreenNavigation, with three failed assertions.
• testPendingWalletSwitchResumesAfterTags has failed CI since at least 15 Oct, for example https://github.com/synonymdev/bitkit-ios/actions/runs/38754121573 on master. It failed in about 17 of the 243 unit-test runs since then.

Out of Scope

• BitkitTests: other intermittent unit-test failures seen in CI (testAutomaticBackupDoesNotRepeatUnrelatedFailures, the UI test host's background assertion timeout).

Automated Checks

• updated SendConfirmationLifecycleTests.swift — the resumed wallet switch after tags waits for the review before it continues

Evidence

• On an iPhone 17 simulator with iOS 27.0, SendConfirmationLifecycleTests passed 14 runs in a row (the last 3 at 9719d7ce, 11 at db3e0d83). Before the change it failed every run, on both master and the parent of feat: add allowances for automatic paykit payments #799.
• SendConfirmationViewTests and SendConfirmationSwipeTests pass.

Gaps

• The CI flake runs on iOS 18 (macos-15), which isn't available locally. Repeated Run Tests runs on this PR confirm it.

Confidence Score: 5/5

[Medium impact] The PR appears safe to merge; no actionable issues were found.

Summary

The review page now owns the wallet-switch task and keeps one live run for an unchanged context.

• Send reviews keep one wallet preparation run for each send context.

Acknowledgment: ovitrif intentionally delays the resumed mock preparation to avoid overlapping the tag pop with the next push.

No findings. Moves the send review's wallet-switch preparation from .task(id:) to a view-owned Task that is kept while its context is unchanged and cancelled when the context changes or the view disappears, and holds the resumed preparation in the tags test until the review is back on screen. Reviewed 9719d7c, full tier, from the code: iOS does not build here, so nothing was run.

What I checked, and 4 candidates I ruled out

Read in full: the lifecycle modifiers and startWalletSwitch in SendConfirmationView.swift, confirmationContext / sendContext / isEditingSendDetails, SendConfirmationLifecycleTests.swift (the tags test, the custom-fee tests and ControlledSendWallet)
CI: SwiftFormat, validate and Greptile green; Run Tests, Run Integration Tests and build-local still pending at review time

Ruled out

• No restart after returning from tags: onChange(initial:) does not fire again when the view reappears, but while .tag is on top confirmationContext is nil, so the watched value is nil, and the pop back changes it to the context. That fires the handler and starts the run, which is what the updated tags test checks.
• A disappear and reappear with an unchanged non-nil value, which leaves the switch cancelled and never restarted: every route off the review (a pushed fee or tag screen, a sheet dismissal or replacement) changes navigationPath.last or the sheet's presentationID, so the watched value changes in both directions.
• A stale run blocks a new one: a finished run sets walletSwitchContext = nil, which sends nil to the handler and clears the run. A run that ends without clearing it is removed by the defer, which checks runID, so a cancelled older task cannot clear a newer run.
• Mock count drift: the second suspend() returns before finished / wasCancelled, so the first assertions on wasCancelled and preparationCount == 1 keep their meaning. suspendsResumedPreparation is set only in the tags test.

Merge confidence: 4/5, no findings, but Run Tests is still pending, and the iOS 18 flake fix is proved only by those CI runs.

Verdict: ✅ Approve

Findings: None.

QA for 9719d7c:

Test 1: send confirmation regression suites ✅ The lifecycle, confirmation and swipe suites passed on iOS 26.5, checked by XCTest assertions.

I built this head and ran SendConfirmationLifecycleTests, SendConfirmationViewTests and SendConfirmationSwipeTests on an iPhone 17 Pro simulator. The assertions cover a single preparation after custom-fee navigation, cancellation and resumption after tags, stale results after send teardown or replacement, and payment gating while preparation is pending.

T1-2x.2x.mp4

Automated test execution at 2× speed; the pass result comes from the XCTest assertions and result bundle.

Check 1: iOS 18 CI coverage ✅ The current-head unit-test job passed.

The Run Tests job passed at 9719d7c using the repository's Xcode 16.4 / iPhone 16 configuration. This is CI evidence, not a separate local device run.

Check 2: full code review ✅ I found no actionable defects in either changed file or the affected callers.

I checked task ownership and deduplication, cancellation, stale completions, sheet replacement, fee/tag navigation, manual coin selection and automatic-payment handoff. SwiftFormat lint and git diff --check passed.

No manual device journey was run: the QA notes list none and declare no user-visible behavior change. Actual payment submission was not driven; the automated suites exercise preparation and confirmation guards.

Coverage: full 35655ae..9719d7c, both changed files and their affected callers.

Android twin: none declared; this fixes SwiftUI lifecycle execution and iOS test navigation, so a matching Android change is not applicable.

Code scan: no findings.

Checked and clean, against what the review screen shows and what gets paid:

• Funding source changed: a new context starts, the old run is cancelled, and its writes are refused by isCurrentSend.
• Amount changed: the context is cleared and the run cancelled. The pay path reads app.selectedWalletToPayFrom at pay time, and the swipe stays blocked until walletSwitchContext is nil, so a stale preparation can't be paid.
• Fee changed: the run restarts when the fee screen pops.
• Background and foreground: identical to master (no onDisappear without PIN, full teardown with PIN). Re-entry gets a new presentationID and fresh @State.
• Android's job-owned refreshOnchainSendIfNeeded already cancels and dedupes, so there is no twin to port.

Performance-relevant (removes a duplicate preparation, visible on iOS 26+). The gate counts Selecting UTXOs with algorithm lines after a fee round trip (expected 1), head vs master, on an iOS 26 simulator, while driving coin-selection/manual-wallet-switch.xml and send/funding-source-dropdown.xml.

Device gate (partial): 9719d7c — not run yet; pending those journeys and that count. Device results will follow in a separate review.

@ovitrif I am resuming active repair of the failing checks on our payment-latency stack. #1054 at d404f925 failed its resumed-preparation expectation (Second send preparation suspended) in run 39919145514 attempt 2; this remains distinct from the earlier extra-visible-route assertion. The same attempt separately failed app launch, which I am investigating in #1110 from the result bundle.

I will preserve your #1098 implementation and avoid a competing fix. Its view hunk applies to our stack, while the test hunk overlaps our earlier resumed-preparation synchronization. Please flag any active amendments or intended integration constraints. Once this is approved and merged, I can reconcile the overlap while preserving one task per current context, cancellation/stale-result guards, and our retained-presentation/app-lock cleanup, then validate the combined current heads. No merge is requested without the required human approvals, and I will not treat #1098 as a fix for the separate launch failure.

[ovitrif]

@ben-kaufman no amendments are planned: 9719d7ce is the final head, green, and it waits only on a human approval. For the merge with your stack, keep these two:

• SendConfirmationView: one live switch run per context, started from startWalletSwitch and cancelled when the context changes or the view disappears. A second start for the same context while a run is live is skipped.
• testPendingWalletSwitchResumesAfterTags: the resumed preparation stays suspended until the review is visible again after the pop from .tag, and only then resumes. Its push must not overlap that transition. The test also asserts preparationCount == 2 after the final wait.

Your retained-presentation and app-lock guards and the single-coin-preparation assertions don't conflict with either.
