fix(native): recover Android wallet startup and privacy controls - #131
Android could leave the header under system bars, keep Unified receive waiting on unrelated HD scans, and show onboarding again after a brief background visit. This keeps the existing wallet visible and inert while reconnecting, then rebuilds its generation-bound providers with the same storage. Lock and network-mode changes still retire the old session. Delayed starts and vault reads cannot publish after suspension, and a changed vault secret fails closed.
Tor starts by default and creation/restore wait for readiness. Direct mode is an explicit, confirmed choice for the current app session. Healthy Arti clients and their directory cache are reused; the wallet module loads alongside connection startup. Direct TCP attempts are bounded, expire stalled addresses, refill slots, retain the first success, and close losing attempts before retirement completes.
Unified, Shielded and Arkade receive now share an exact-sats input and produce BIP21 links that round-trip through the send decoder. Raw invalid input stays visible with an error instead of silently changing the amount or falling back to an address-only QR. Missing or restore-masked addresses cannot become amount QRs, and Unified links normalize LNURL values to lowercase. Invoice limits load when the disclosure opens; unknown or out-of-range limits prevent invoice creation, and stale limit reads cannot overwrite newer results.
Unified startup exposes recovery after failure; retries that reload wait for tracked background actions, with the same 30-minute UI timeout as ordinary payments. That timeout does not cancel or complete the underlying payment or release its journaled input reservations. Balance failures have recoverable status rather than an unexplained indefinite spinner. Suspension closes the scanner and prevents reopening while reconnecting. Android insets use consistent window coordinates, restore baseline padding when insets shrink, and consume handled system-bar/cutout insets before WebView forwarding while retaining IME updates.
The shared web/native wallet gets a shield-and-ripple entrance, skipped on brief native resume and with reduced motion. Onboarding privacy opens upward inside the viewport, while the central stage remains scrollable on short screens.
Validation:
Full local suite for 5ae51eb: 1,393 passed, zero failed/skipped. TypeScript checking passes. The SDK-handle regression proves that the UI timeout does not cancel or complete a pending payment.
Rust workspace: 46 passed. Cargo formatting, web production build and native frontend build pass.
Lifecycle models: all 18 configurations matched their expected results.
Actual Tor smoke: independent scopes returned HTTP 200, with Tor Project returning IsTor=true both before and after resume; before-open cancellation, in-flight pause and stale-generation rejection passed. Measured process starts ranged from 3.0 to 15.6 seconds across fresh/cached runs; in-process resume measured below 1 ms, with fresh isolated requests still taking several seconds. These are observations, not latency guarantees.
Rendered NativeWallet fixture with an in-memory backend: no wallet creation/vault read before Tor readiness; privacy expands upward without page scroll; the wallet remains present/inert through background/reconnection and resumes without onboarding or replaying the entrance. This is renderer coverage, not a physical Android test.
Rendered ReceivePortal: decimal, leading-zero and oversized pasted amounts preserve their raw text and suppress QR/link generation across all three tabs; 330 sats produces the corresponding exact BIP21 amount, and the copied request matches it.
5ae51eb passes native CI for Windows, Linux, universal macOS, Android and unsigned iOS packages, plus Checks CI. Both full CI test runs pass; the PR-triggered log records 1,393 passing tests with zero failures/skips. Arkana's current-head review reports no blocking findings, and independent lifecycle/receive reviews found no remaining material issue. All review threads are resolved. CodeRabbit's current-head review was rate-limited; its success context is not fresh review approval, and the earlier actionable findings were addressed with focused regressions and rendered checks.
Physical Android status-bar/cutout/keyboard behavior, native foreground rendering, and funded payments remain unverified. No funds were moved, and the real wallet seed/app data were not read or changed by the fixture.
The native transport now supports Tor and direct connections. Wallet controls, setup, and status reporting reflect the selected mode. Wallet receiving, startup, and sync reporting have also changed. The Android plugin now applies safe insets to the WebView’s parent container.
Changes
Native connection modes and wallet readiness
Layer / File(s)
Summary
Mode contract and direct transport src-tauri/src/transport/mod.rs, src-tauri/src/transport/direct.rs, src-tauri/Cargo.toml
Native status includes a mode, and native start accepts an optional mode that defaults to Tor. Direct connections resolve once, validate address results, and attempt connections with cancellation and timeout handling.
Mode-aware sessions and connections src-tauri/src/transport/session.rs, src-tauri/src/transport/wire.rs
Sessions track the selected mode and wait for tracked resources to retire during mode changes. Leases connect through the selected transport. HTTP and WebSocket setup use the lease connection method.
The bridge forwards mode selections and accepts statuses according to mode and generation. Vault opening and setup validate connection state. Polling errors preserve existing status fields.
The wallet supports mode switching, confirms before switching from Tor to direct, and displays mode-specific connection and privacy details. Onboarding disables actions while transport changes or setup waits for readiness.
Wallet startup and sync status app/src/RollupWallet.tsx, app/src/WalletSyncStatus.tsx, app/src/shielded-page.ts, tests/native-lightning-startup.test.ts, tests/wallet-sync-status.test.ts, tests/shielded-page.test.ts
The wallet tracks payment handles and native refresh failures. The balance card reports private and Arkade readiness, with retry behavior on errors. Native Lightning startup uses lazy initialization.
The receive form accepts a satoshi amount and generates a mode-specific Bitcoin URI. Payment links can select the shielded destination.
Android WebView safe insets

The Android plugin adds AndroidX Core KTX and applies system-bar and display-cutout safe insets to the WebView parent container.

Merge Risk: Low · previous review a3d6f
The remaining issues are bounded: malformed amounts can produce misleading requests, invoice limits are unavailable before submission, suspension can leave the scanner active, and Android onboarding can gain extra top spacing. These warrant focused fixes or explicit follow-up, but no broad startup or transport failure is established.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
The listener always adds reported system-bar and cutout insets to the parent padding. If the Android window already fits its content within those areas, the new padding could apply the safe offset a second time.
A persistent blank band can appear above or below the wallet and shrink its viewport.
This can occur when: A supported Android host configuration positions the WebView's parent below the status bar while still dispatching nonzero system-bar insets to it.

1. Android padding accumulates on each WebView reload —
already has , confirming it is called on each WebView (re-)attach. The first call captures the original pre-inset container padding and applies . The second call captures the now-modified padding (which already contains ) and applies — doubling the status-bar / cutout offset. Each subsequent reload accumulates further.
Suggested fix — persist the original padding before the first mutation (the view's tag is a convenient slot since replaces the listener each time):
This needs an Android device smoke test to confirm: lock → unlock (triggers reload) leaves the topbar flush rather than increasingly offset.
2. Stale closure makes the fence a no-op —
is React state; with captures the initial value for the component's lifetime. As a result is permanently , making the check — false for every real generation — so the generation fence never fires.
In practice the mode check (, which reads via the closure on the backend result) keeps correctness intact; there is no known exploit path. However 's generation parameter was clearly designed to require a fresh generation after a mode transition, and the existing unit tests for validate that behaviour. The intent is broken.
Fix: either add to deps, or capture the generation into a ref that can read:
Notable (non-blocking, follow-up welcome)
**3. arti feature — **
enables , used to block mode transitions until the Tor client actually stops. The version is pinned () which limits the blast radius, but this feature flag opts into APIs that arti reserves the right to change between patch releases. Document the specific method and the arti issue/PR that stabilises it so the next pin-bump has a checklist item.
**4. is long for mobile — **
A TCP handshake that stalls for 90 seconds holds the retirement token and blocks any subsequent mode switch (which must drain all retirements within , immediately erroring). On lossy mobile links this is the common failure path. Consider a shorter timeout (e.g. 15–20 s) with the expectation that the user retries, or expose the timeout as a configurable constant that can be tightened per-platform.
The check for IPv6 allows any address not matching the specific exclusions. ( for ) is IANA-reserved for Protocol Assignments (ORCHIDv2 is in and is already blocked by ). These addresses are not routable end-user destinations and are unlikely to be returned by real DNS, but are technically not "public internet" addresses. Low practical risk; worth a comment explaining the allowed range and linking to the IANA allocation table so the next person reviewing this doesn't have to reconstruct it.
6. in direct mode returns an error but has no socket-path test
on a direct-mode lease correctly propagates the error from (verified by ). The WebSocket path was updated to use and therefore goes through the same gate. Consider adding a minimal test for the WebSocket direct-mode path in to lock that in.
What looks good
Retirement / drain lifecycle: held in prevents a mode switch from proceeding while an active TCP/TLS/WebSocket stream is alive. The 10 s drain timeout with an explicit error-and-retry pattern (instead of a silent hang) is the right tradeoff. Test coverage for the drain timeout, the pause-during-switch race, and the generation-increment-on-mode-change is thorough.
No automatic Tor → direct fallback: confirmed both in Rust () and TS ( explicit mode mismatch throw). The PR description claim holds.
Mixed DNS rejection: correctly blocks the whole batch, not just the private address. Prevents split-DNS attacks.
** write fence**: key generation happens after the mode/generation check; a second check (covering ) guards the write; the promise is awaited by before is called. The pipeline is correctly ordered.
** / **: the dormant-then-wait pattern avoids a bare that would leave Tor background tasks racing the new mode's connections.
UI copy: direct-mode warning in confirmation dialog, panel text, and onboarding all consistently state IP/DNS exposure and no circuit isolation. No claim that direct is equivalent to Tor.
Cross-repo impact: and the updated are internal to this repo's native layer; no SDK consumers in ts-sdk / go-sdk / rust-sdk / dotnet-sdk reference these types.
load() already has generation++, confirming it is called on each WebView (re-)attach. The first call captures the original pre-inset container padding and applies original + safe. The second call captures the now-modified padding (which already contains safe) and applies modified + safe — doubling the status-bar / cutout offset. Each subsequent reload accumulates further.
Suggested fix — persist the original padding before the first mutation (the view's tag is a convenient slot since setOnApplyWindowInsetsListener replaces the listener each time):
This needs an Android device smoke test: lock → unlock (triggers WebView reload) should leave the topbar flush rather than increasingly offset.
2. Stale torHealth closure makes the generationAfter fence a no-op — NativeWallet.tsx
// open callback, deps = []constopen=useCallback(()=>{
...
constopened=awaitopenNativeVault(()=>nativeNetwork.start(selectedMode.current),getSecret,()=>mine===attempt.current&& ...,{generationAfter: torHealth.status.generation,// always 0 (initial state)mode: selectedMode.current});},[]);// torHealth never added to deps
torHealth is React state; useCallback with [] captures the initial value {status:{phase:'idle',generation:0},check:'idle'} for the component's lifetime. As a result generationAfter is permanently 0, and the openNativeVault check status.generation <= 0 is false for every real generation — so the generation fence never fires.
In practice the mode check ((status.mode??'tor') !== expected.mode, which reads selectedMode.current via the backend start() result) keeps correctness intact; there is no known exploit path. However openNativeVault's generation parameter was clearly designed to require a fresh generation after a mode transition, and the existing unit tests for openNativeVault validate that behaviour. The intent is broken.
Fix: capture the generation into a ref that open can read without a stale closure:
consttorGeneration=useRef(0);// update it wherever setTorHealth is called:torGeneration.current=status.generation;// in open:{generationAfter: torGeneration.current,mode: selectedMode.current}
Notable (non-blocking, follow-up welcome)
3. experimental-api arti feature — src-tauri/Cargo.toml
experimental-api enables wait_for_stop(), used to block mode transitions until the Tor client actually stops. The version is pinned (=0.48.0) which limits the blast radius, but this feature flag opts into APIs that arti reserves the right to change between patch releases. Document the specific method and the arti issue/PR that stabilises it so the next pin-bump has a checklist item.
4. CONNECT_TIMEOUT = 90s is long for mobile — direct.rs
A TCP handshake stalled for 90 seconds holds the retirement token and blocks any subsequent mode switch (which must drain all retirements within DRAIN_TIMEOUT = 10s, immediately erroring). On lossy mobile links this is the common failure path. Consider a shorter timeout (e.g. 15–20 s) with the expectation that the user retries, or expose the timeout as a configurable constant that can be tightened per-platform.
The public_address check for IPv6 allows any 0x2000..=0x3fff address not matching the specific exclusions. 2001:0200::/23 (b >= 0x200 for a == 0x2001) is IANA-reserved for Protocol Assignments. These addresses are not routable end-user destinations and are unlikely to be returned by real DNS, but are technically not "public internet" addresses. Low practical risk; a comment explaining the allowed range and linking to the IANA allocation table would help the next reviewer.
6. reconnect_client in direct mode — no WebSocket path test
connect_with_recovery on a direct-mode lease correctly propagates the Tor is unavailable in direct mode error from self.context.tor()? (verified by direct_start_is_explicit_idempotent_and_never_creates_a_tor_client). The socket_inner WebSocket path in wire.rs was updated to use lease.connect(host) and goes through the same gate. Consider adding a minimal test for the WebSocket direct-mode path to lock that in.
What looks good
Retirement / drain lifecycle: Arc<Retirement> held in NativeStream._retirement prevents a mode switch from proceeding while an active TCP/TLS/WebSocket stream is alive. The 10 s drain timeout with an explicit error-and-retry pattern is the right tradeoff. Test coverage for the drain timeout, the pause-during-switch race, and generation-increment-on-mode-change is thorough.
No automatic Tor → direct fallback: confirmed both in Rust (tor_initialization_failure_retains_tor_mode_without_direct_fallback) and TS (transport.ts explicit mode-mismatch throw). The PR description claim holds.
Mixed DNS rejection: a_mixed_dns_result_never_connects_even_to_its_public_address rejects the whole batch if any address is non-public. Prevents split-DNS attacks where a private address is included alongside a legitimate one.
saveNativeSetup write fence: key generation happens after the mode/generation check; a second current() check (covering transition.current) guards the write; the creating.current promise is awaited by pause() before nativeNetwork.pause() is called. The pipeline is correctly ordered.
wait_for_stop() dormancy pattern: the dormant-then-wait approach avoids a bare drop(client) that would leave Tor background tasks racing the new mode's connections.
UI copy: direct-mode warning in confirmation dialog, panel text, and onboarding all consistently state IP/DNS exposure and no circuit isolation. No claim that direct is equivalent to Tor.
Cross-repo impact: NativeMode and the updated NativeStatus are internal to this repo's native layer; no SDK consumers in ts-sdk / go-sdk / rust-sdk / dotnet-sdk reference these types.
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
A nonzero existing top or left padding prevents any additional safe-area padding, regardless of whether that padding is sufficient; the listener then reports zero applied inset for that edge.
The first 16 pixels of WebView content may remain behind the status bar.
This can occur when: The container starts with 8 pixels of top padding but the status-bar inset is 24 pixels.

The reason will be displayed to describe this comment to others. Learn more.
Follow-up pass on ecc75b4 (1 commit since c910677). Prior issue 1 fixed; prior issue 2 still open and now worse; two new blockers introduced in the incremental diff.
Prior-issue closure
Issue 1 — Android padding accumulates on WebView reload
Fixed (ecc75b4). The WeakHashMap<View, Insets> at module scope captures each container's original padding exactly once. The getOrPut call correctly returns the stored baseline on every subsequent load() invocation. ✓
However the same commit introduces a new Android build failure at the same file — see finding A below.
Issue 2 — Stale torHealth closure makes generationAfter fence a no-op
Still open, worse. The API was renamed from generationAfter / <= to generation / !==, which tightens the check from "any generation strictly greater than" to "exact equality". That is the right direction, but the value passed at the call site is still wrong:
openingGeneration.current is undefined at the moment the options object is evaluated (before the starter lambda runs). JavaScript evaluates arguments left-to-right and eagerly, so expected.generation is -1 for every call. nativeNetwork.start() never returns generation: -1 — it returns a real generational counter ≥ 0 — so status.generation !== -1 is permanently true, and openNativeVault returns undefined on every invocation. The wallet can never open.
The companion openingGeneration.current = status.generation inside the starter is correctly sequenced, but it is set afterexpected has already been closed over. The monitor expiry path (healthExpired.current) is correctly gated and would work if the wallet could open; it never gets the chance.
The existing test ('the vault is read only for the requested mode and a new generation') only exercises expected.generation === status.generation; there is no test for expected.generation === -1, so the regression is not caught.
Minimal correct fix — either use a getter so the ref is read at check time:
…or drop the expected.generation check entirely and rely solely on generationGuard() → healthExpired.current, which already covers the same race. Either approach unblocks wallet opening while keeping the health-expiry fence intact.
Issues 3–6 (notable, non-blocking)
No change to Cargo.toml comments, CONNECT_TIMEOUT, the IPv6 2001:0200::/23 gap, or the WebSocket direct-mode test. All remain open as previously documented.
A. Kotlin comma-separated val declarations do not compile — ShieldedPlatformPlugin.kt
src-tauri/plugins/shielded-platform/android/src/main/java/io/arkade/shielded/platform/ShieldedPlatformPlugin.kt lines added in this commit:
val leftBound = view.translationX.toInt(), topBound = view.translationY.toInt()
val windowLeft = view.left + leftBound, windowTop = view.top + topBound
val windowRight = view.right + leftBound, windowBottom = view.bottom + topBound
Kotlin does not support multiple variable declarations in a single val statement with comma separation. Each variable requires its own val. The Kotlin compiler will reject these lines, blocking every Android build. The logic itself is sound — the inset-conditional padding is a good improvement — but the syntax must be fixed:
val leftBound = view.translationX.toInt()
val topBound = view.translationY.toInt()
val windowLeft = view.left + leftBound
val windowTop = view.top + topBound
val windowRight = view.right + leftBound
val windowBottom = view.bottom + topBound
B. reload() branch on "Retry unified address" is unreachable — RollupWallet.tsx
The button is disabled when !wallet?.swaps || !lnurlRef.current. The else if branch that calls reload() is reachable only when that condition is true — but the button cannot be clicked in that state. When Lightning startup fails (lnError set, wallet?.swaps missing), the user sees the button but cannot interact with it, with no other affordance to recover. The disabled condition should allow the button when startupError || lnError and no operation is in flight, even if service prerequisites are absent.
What is good in the incremental diff
direct.rs JoinSet: switching from sequential to concurrent TCP attempts is correct and the new test a_stalled_address_does_not_hide_a_reachable_later_address locks in the happy-eyeballs behaviour. MAX_ADDRESSES = 64 concurrent attempts is aggressive on mobile but non-blocking.
expected.current() guard in openNativeVault: the two new expected.current() checks around the secret read correctly fence health expiry between DNS and vault operations — good defence in depth even though the outer generation check is broken.
unifiedRetry.current ??= serialisation: prevents overlapping retryUnified calls; a correct addition.
WalletSyncStatusonRetry? optional: correctly handles the case where no retry is wired up.
Two blockers remain before merge: issue 2 (wallet never opens) and finding A (Android build fails). Finding B should be fixed in the same pass.
Each attempt sleeps for 10 ms, while the launch delay is 50 ms. Attempts can finish before the next launch, so removing the limit can leave this test passing.
Hold eight attempts pending across another launch opportunity and assert that a ninth does not start. Then release one attempt and verify progress.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
The listener forwards the calculated handled inset amounts to descendants even when it has applied those amounts as container padding. A descendant that also handles system-bar or cutout insets may therefore apply them twice.
Wallet content gains duplicate safe-area spacing.
This can occur when: The WebView or its content consumes a top inset after the container has already added top padding.
62-65: Minor · Potential issue · Quick win
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Padding is updated only when a newly calculated inset is positive; there is no path that restores the cached base padding when an inset becomes unnecessary.
The wallet retains obsolete blank space instead of expanding into the newly available area.
This can occur when: A previously applied top safe inset disappears, such as after a system-bar visibility change, and the container remains in use.

view.left, top, right, and bottom are parent-relative positions, but the calculation treats them as window coordinates. An ancestor’s offset can therefore cause padding to be applied for an edge the container does not cross.
The listener adds unnecessary top padding, shifting the wallet below its available area.
This can occur when: The container’s ancestor is already positioned below a 24-pixel status bar while the container’s parent-relative top is zero.

- Line 564: Update the retry button’s reload path in the unified-address handler
to wait until wallet-originated actions have reached a safe completion boundary
before calling reload. The existing busy and handleBusy checks do not cover
actions started through onAction, so use the established action-tracking
mechanism to coordinate reload without interrupting shielding.

- Around line 58-59: Update the topInset and leftInset calculations to derive
required padding from the view’s original padding rather than its current
padding on each inset pass. Preserve the existing safe-area and
nonnegative-padding behavior while ensuring repeated inset updates calculate the
full required padding independently.
- Around line 60-61: Update the rightInset and bottomInset calculations to
measure overlap against the window’s right and bottom edges rather than
safe.right and safe.bottom, while preserving the existing padding adjustment and
nonnegative clamping so the WebView retains its layout space.
Review comments at @src-tauri/src/transport/direct.rs:
- Line 72: Update the direct connection attempt handling around
attempts.spawn(connect(address)) so mode-switch cancellation does not release
the retirement barrier until every losing attempt has finished and its socket
has closed. Preserve the existing cancellation behavior while explicitly waiting
for aborted attempts to complete before allowing Tor bootstrap to start.
- Around line 85-86: Update the retry scheduling around the `tokio::time::sleep`
branch so stalled addresses can expire or rotate out, allowing pending addresses
to be attempted before the overall timeout. Preserve the `MAX_ATTEMPTS`
concurrency bound while ensuring stalled attempts do not permanently occupy all
available slots.

Follow-up pass on bee7585 (2 commits since ecc75b4). Issues 2, A, and B from last pass are now fixed. One new Android blocker introduced in this diff; prior issues 3–6 remain open.
Prior-issue closure
Issue 1 — Android padding accumulates on WebView reload
Fixed in ecc75b4 (confirmed still present and correct). WeakHashMap<View, Insets> baseline capture is intact in this diff.
Issue 2 — Stale torHealth closure makes generationAfter fence a no-op
Fixed (bee7585). app/src/NativeWallet.tsx now uses (await nativeNetwork.status()).generation to capture the current generation at call time before the starter runs. This replaces both the stale initial-state read (torHealth.status.generation = 0) and the prior -1 sentinel mistake. The healthExpired.current ref correctly flags health changes observed between start() returning and the secret read completing. ✓
Finding A — Kotlin comma-separated val declarations do not compile
Fixed (bee7585). Each variable is now its own val declaration. ✓
Finding B — reload() branch on "Retry unified address" is unreachable
Fixed (bee7585). app/src/RollupWallet.tsx line ~561: the disabled condition now permits the button when (startupError||lnError)&&!handleBusy.current, making the else if … reload() path reachable when Lightning startup has failed. ✓
Issues 3–6 (notable, non-blocking)
No change to Cargo.toml comments, CONNECT_TIMEOUT = 90 s, the 2001:0200::/23 IPv6 gap, or the WebSocket direct-mode test. All remain open as previously documented. CONNECT_TIMEOUT interacts with the new MAX_ATTEMPTS = 8 happy-eyeballs loop: the worst-case mode-switch latency is still up to 90 s per retirement.
A — Android right/bottom inset comparisons use incompatible coordinate systems — ShieldedPlatformPlugin.kt
src-tauri/plugins/shielded-platform/android/src/main/java/io/arkade/shielded/platform/ShieldedPlatformPlugin.kt (lines added in bee7585):
val safe = insets.getInsets(handledTypes)
// safe.left / safe.top / safe.right / safe.bottom are INSET AMOUNTS (edge-inward pixels)// e.g. safe.top=100 (status bar), safe.right=0 (no right cutout in portrait)val windowRight = view.right + leftBound // LAYOUT COORDINATE, e.g. 1080val windowBottom = view.bottom + topBound // LAYOUT COORDINATE, e.g. 1920val rightInset =if (windowRight > safe.right) (windowRight - safe.right - view.paddingRight).coerceAtLeast(0) else0// ^-- 1080 > 0 is ALWAYS true for any screen with no right cutout// rightInset = 1080 - 0 - 0 = 1080val bottomInset =if (windowBottom > safe.bottom) (windowBottom - safe.bottom - view.paddingBottom).coerceAtLeast(0) else0// ^-- 1920 > 48 is ALWAYS true for any screen with a navigation bar// bottomInset = 1920 - 48 - 0 = 1872
WindowInsetsCompat.getInsets() returns directional inset amounts (small values, 0–50 px), not threshold coordinates. safe.right = 0 for a portrait phone with no right cutout; safe.bottom = 48 for a standard navigation bar. These are incompatible units with view.right / view.bottom, which are layout coordinates (order of hundreds to thousands of pixels).
Consequence: on the first insets callback the container receives approximately 1080 px of right padding and 1872 px of bottom padding, collapsing the WebView to near-zero visible area. Android users will see a blank screen on first launch and after every WebView re-attach.
The left/top branches work by coincidence: safe.left and safe.top are measured from the same edge as view.left / view.top, so the comparison view.left < safe.left (e.g., 0 < 44) correctly detects overlap. For right and bottom the threshold coordinate from the left is screen_width - safe.right, not safe.right.
Additionally, view.paddingRight / view.paddingBottom in the formula read the current (already mutated) padding from prior callbacks, not the original baseline in padding. On the second callback rightInset = 1080 - 0 - (padding.right + 1080) → coerces to 0 → setPadding is skipped. The WebView stays collapsed from the first callback.
The if (topInset > 0 || …) guard also means that when all insets legitimately become 0 (system UI hidden, full-screen mode), setPadding is not called and the stale positive padding persists — a secondary stale-padding regression distinct from issue 1.
Suggested fix:
val screenWidth = view.rootView.width
val screenHeight = view.rootView.height
val rightInset =if (screenWidth >0&& windowRight > screenWidth - safe.right)
(windowRight - (screenWidth - safe.right)).coerceAtLeast(0)
else0val bottomInset =if (screenHeight >0&& windowBottom > screenHeight - safe.bottom)
(windowBottom - (screenHeight - safe.bottom)).coerceAtLeast(0)
else0// Always call setPadding — do not guard on > 0 — so stale padding clears when insets shrink.
view.setPadding(
padding.left + leftInset, padding.top + topInset,
padding.right + rightInset, padding.bottom + bottomInset
)
Also replace view.paddingLeft / view.paddingTop in the top/left formulas with padding.left / padding.top (the baseInsets-frozen originals) to avoid the current-state dependency:
openNativeVault two-point expected.current() guards: the checks around the secret read correctly fence health expiry between DNS resolution and vault access — good defence in depth.
healthExpired monitor probe: tying openingGeneration.current to the health monitor and using it to gate the post-open if(healthExpired.current)return is a clean pattern.
handleBusy.current lifecycle (RollupWallet.tsx): properly cleared in finally on start() failure and after settled(), preventing the busy guard from locking the UI permanently after an error.
direct.rs happy-eyeballs: switching from sequential to concurrent TCP attempts with JoinSet and MAX_ATTEMPTS = 8 is correct. a_stalled_address_does_not_hide_a_reachable_later_address and connection_attempts_are_bounded_and_later_addresses_can_succeed are solid tests covering the key properties.
NativeTorHealth.tsx direct-mode label/state refinement: correctly surfaces direct-mode error/paused states separately from Tor states.
One blocker before merge: finding A (Android WebView collapsed on first insets callback).
The reason will be displayed to describe this comment to others. Learn more.
Follow-up pass on a3d6fb8 (1 commit since bee7585). Prior blocker (Finding A — Android WebView collapsed) is now fixed; 1 of 4 prior non-blocking issues is now resolved; 3 remain open. Two new minor findings in the incremental diff.
Prior-issue closure
Finding A — Android right/bottom inset coordinate-system mismatch
All four points from the prior suggestion are addressed:
view.getLocationInWindow(position) replaces translationX/Y for reliable window position.
Right/bottom thresholds now use view.rootView.width/height as the screen-edge anchor (windowRight > rightEdge - safe.right).
padding.left/top/right/bottom from the WeakHashMap baseline replace the mutable view.paddingLeft/Top/Right/Bottom.
The if (topInset > 0 || …) guard is gone; setPadding is called unconditionally, so stale positive padding clears when insets go to zero.
One micro-note (non-blocking): the forwarded WindowInsetsCompat at the end passes Insets.of(leftInset, topInset, rightInset, bottomInset) as the "remaining" insets for downstream views. These are overlap amounts (e.g., safe.top - windowTop - padding.top), not the full original inset values, so the WebView may see underreported remaining insets. In practice this only affects soft-keyboard handling and the comment makes the intent clear. Not worth blocking on.
Still open — none of these files changed in this diff. The IPv6 gap is worth calling out explicitly: src-tauri/src/transport/direct.rs excludes 2001:0000::/23 via a == 0x2001 && b < 0x0200, but 2001:0200::/23 (IETF Protocol Assignments, b = 0x0200–0x03FF) is not excluded. No test vector covers [2001:0200::1]:443. An address in that range would pass public_address() and be dialled directly. The range is globally routable but IANA-special; connections to it are unlikely in practice, so not a blocker, but the exclusion is incomplete.
New findings from this diff
1. pageActions.track() calls handle.settled() without a timeout — app/src/shielded-page.ts
run() in RollupWallet.tsx calls handle.settled({timeoutMs:30*60_000}). pageActions.track() calls it without any timeout. If a handle never resolves — stuck protocol, lost connection during a payment — actions.current.busy stays true indefinitely. The ref persists across reconnects (it is never reset between sessions; actions.current??= initialises it once). Effect: in a stuck-handle scenario, the reload button (RollupWallet.tsx:527: busy||handleBusy.current||actions.current!.busy?undefined:reload) and the "Retry unified address" button (RollupWallet.tsx:569) are permanently disabled until the user force-quits the app.
A PaymentHandle that the user cannot clear is a recoverable-funds problem. Recommend passing the same 30-minute cap: handle.settled({timeoutMs:30*60_000}), or keying actions to the wallet session so it resets on reconnect.
2. LNURL value passed unmodified into BIP21 URI — app/src/wallet-receive.tsx
LUD-01 specifies LNURL strings as lowercase bech32. The UI may hand amountQrValue an uppercase LNURL1… string (the test does exactly this: 'LNURL1EXAMPLE'). Some LNURL-aware BIP21 parsers, particularly mobile wallets that do strict case matching on the lightning= parameter, may fail to decode an uppercase LNURL. The payTarget roundtrip in the test passes only because plain() normalises on the way back, not because the URI is well-formed. Non-blocking, but worth a value.toLowerCase() for the lightning branch.
What is good in the incremental diff
resumeNativeForeground: the new function correctly sequences await pending → current() → open(). The five new tests cover the key concurrent-resume race conditions (double hide/show, lock before pending settles, stale opening race). These are solid.
openNativeVault generation parameter made optional and the new test 'opening accepts the generation created by native start rather than the paused generation' closes the semantic gap cleanly.
suspend() + reconnecting state: splitting pause (manual lock/mode switch) from suspend (health failure) with reconnecting=true preserves the mounted wallet during reconnect. The walletMounted.current gate (reconnecting&&!walletMounted.current?null:<Suspense>…) prevents a flicker by holding the previous wallet in place until the new session's component has reported ready. Clean.
Secret-change detection on resume: resume.cache.storage.getItem('shielded-rollup-wallet-secret-v1')!==secret → throw. Correct guard against vault rotation while the UI was reconnecting.
pageActionsbusy deduplication: if(pending.has(handle))return prevents double-tracking the same handle. ✓
payTarget now handles shielded= BIP21 parameter (rollup-client.ts) — required by the new amountQrValue output. Test coverage in receive-amount.test.ts is thorough.
direct.rs happy-eyeballs with FuturesUnordered and ATTEMPT_LIFETIME: the switch from JoinSet removes the per-slot ATTEMPT_DELAY serialisation. Stalled addresses now expire after 5 s, freeing their slot without waiting. The new tests failed_attempt_refills_available_capacity_without_another_delay and stalled_attempts_expire_and_losing_attempts_finish_before_cancellation cover the key properties. The Cleanup drop-count assertion correctly verifies all 9 futures are released on cancellation. ✓
Two issues need resolution before merge: Finding 1 (stuck-handle permanent lock) is the more important one; Finding 2 is minor but straightforward to fix.
The reason will be displayed to describe this comment to others. Learn more.
Follow-up pass on 6e0977c (1 commit since a3d6fb8). Both findings from the last pass are now fixed. Issues 3–6 (non-blocking) remain open and unchanged.
The 30-minute cap matches the existing run() timeout in RollupWallet.tsx, so both timeouts fire together. The new test 'a stuck action stops blocking recovery after the UI timeout without cancelling the payment' (tests/shielded-page.test.ts:37–44) correctly verifies three invariants in sequence: (1) actions.busy=false after the timer fires — the UI lock releases; (2) completed=false and handle.status='pending' — the underlying payment is not cancelled; (3) after done.resolve(), handle.settled() resolves normally — the handle can still be settled by the protocol after the UI gave up waiting. The timeout-on-wait vs timeout-on-operation distinction is precisely what needed testing. ✓
Finding 2 — LNURL value not normalised to lowercase in BIP21 URI
Lowercase normalisation is applied only to the lightning= BIP21 parameter (unified mode), which is correct: LNURL is lowercase bech32 (LUD-01) and Lightning addresses are case-insensitive in practice. Ark/shielded addresses are left untouched. The test update in tests/receive-amount.test.ts:34 documents the expectation correctly. ✓
Still open. None of these files were touched in this diff. Reiterating the IPv6 item for visibility since it is the highest-impact of the four: src-tauri/src/transport/direct.rs excludes 2001:0000::/23 via a == 0x2001 && b < 0x0200 but does not exclude 2001:0200::/23 (IETF Protocol Assignments, b = 0x0200–0x03FF). An address in that range passes public_address() and is dialled directly. Connections to that range are unlikely in practice; this is non-blocking but the exclusion is incomplete. The other three items are documentation/test-coverage gaps, not runtime defects.
Incremental diff assessment
Both changes are minimal, targeted, and well-tested. No new issues introduced. The PR is clear to merge once the team is comfortable with the four pre-existing non-blocking items above.

5ae51eb addresses the five new CodeRabbit findings: raw receive amounts are validated without stripping characters or falling back to a bare address; invoice limits load on open and gate creation; suspension unmounts the scanner; and Android consumes handled system-bar/cutout insets while retaining IME updates. The full local suite passes 1,393 tests. Rendered interaction checks cover invalid pastes and valid exact amounts on all three receive tabs. The Tor smoke now independently checks IsTor=true after resume, and the connection-refill test reaches the ninth address while seven earlier attempts remain pending.
The repeated IPv6 finding is not a policy gap: IANA lists 2001:200::/23 as allocated to APNIC in the global-unicast registry. The special-purpose registry lists IETF assignments as 2001::/23 and benchmarking as 2001:2::/48; both are already rejected by b < 0x0200. The tests now explicitly accept [2001:0200::1]:443 and reject [2001:2::1]:443 to preserve that distinction. No address-policy change was made.

Follow-up pass on 5ae51eb (1 commit since 6e0977c). Prior items: 3 of 6 now closed (Findings 1–2 were already fixed at 6e0977c; IPv6 2001:0200::/23 test-gap closed in this diff). 3 non-blocking items remain. No new blocking findings.
Fixed (6e0977c) — documented in the previous pass. No change in this diff.
Issue: IPv6 2001:0200::/23 gap in public_address()
Addressed by explicit test coverage (this diff, src-tauri/src/transport/direct.rs:162).
The new test vector [2001:0200::1]:443 added to the allowed list confirms the existing logic was correct all along: a == 0x2001 && b < 0x0200 excludes only the IETF Protocol Assignments sub-ranges below 2001:0200:: (Teredo at 0x0000, benchmarking at 0x0002, ORCHIDv2 at 0x0020, etc.). The range starting at b=0x0200 has no IANA special-purpose assignment and is globally routable unicast — treating it as dialable is right.
The companion addition of [2001:2::1]:443 (b=0x0002) to the blocked list documents the boundary of the existing exclusion, closing the coverage gap without any code change. Prior concern was unfounded; the fix is the test.
Triple-guarded: (1) the effect clears scanning state when suspended becomes true; (2) the Scanner component doesn't mount while suspended ({scanning&&!suspended&&<Scanner…/>} at line 665); (3) the scan button is disabled={suspended}. The scanner cannot remain open through a suspend event.
Issues: Cargo.toml, CONNECT_TIMEOUT = 90 s, WebSocket direct-mode test
Still open. None of these files are in this diff. These remain non-blocking documentation/coverage gaps; repeating them so they don't silently disappear:
src-tauri/Cargo.toml: transport dependency version pinning concern.
src-tauri/src/transport/direct.rs:11: CONNECT_TIMEOUT = 90 s is long for a mobile happy-eyeballs loop where the outer CONNECT_TIMEOUT already bounds the full dial. Consider a shorter wall-clock cap (e.g. 30 s) matched to typical mobile TCP timeouts.
src-tauri/src/transport/: No WebSocket test for direct mode (Tor WebSocket paths are tested; direct WS path is not).
Android plugin micro-note — now properly resolved
The prior pass noted that the forwarded insets used overlap amounts rather than the original inset values (Insets.of(leftInset, topInset, rightInset, bottomInset)), which could over-report remaining insets to the WebView.
This diff (src-tauri/plugins/…/ShieldedPlatformPlugin.kt:69) changes that to Insets.NONE:
handledTypes is systemBars() or displayCutout() — IME is not included, so soft-keyboard insets still flow to the WebView unmodified. The container declares itself the terminal handler for system-bar and cutout insets, which is semantically correct since it applies the padding unconditionally. Prior micro-note is closed.
Incremental diff — new observations
direct.rs happy-eyeballs test expansion (non-blocking note)
src-tauri/src/transport/direct.rs:369: the test now uses 9 addresses (1..=9) with MAX_ATTEMPTS=8, where attempt 1 fails immediately, attempts 2–8 stall, and attempt 9 succeeds. This correctly exercises the capacity-refill path: the failed slot opens room for address 9 before ATTEMPT_LIFETIME fires. The ATTEMPT_LIFETIME timeout (250 ms in test mode) wraps each pending future; since attempt 9 resolves synchronously to Ok(19), the test completes well within the stall window. ✓
app/src/wallet-receive.tsx:36: the regex /^[1-9]\d{0,9}$/ accepts 1–10 digit positive integers (max 9,999,999,999 sats ≈ 100 BTC). All leakage paths (QR, address display, copy, share, action slot) are gated through displayValue = invalidAmount ? '' : value (line 59). The aria-invalid / aria-describedby / role="alert" wiring at lines 113–115 is correct. The error text at line 115 precisely matches the validation boundary.
One observation: invoiceRequestAmount (line 37–39) correctly returns undefined when bounds haven't loaded yet, disabling the invoice button until limits are known. The lnBoundsError state with its "Retry invoice limits" button (RollupWallet.tsx:597) handles the fetch-failure case; both state variables are cleared together on wallet/swaps change (line 365) and at the start of each fetch attempt (line 370). ✓
transport_smoke.rs post-resume Tor verification
src-tauri/examples/transport_smoke.rs:136: adding verify_tor(&transport, resumed.generation, "tor-check-resumed") after the wallet-resume path closes the gap where the smoke test previously verified Tor only before the vault open. Extracting the check into a named helper makes the intent clear and avoids drift between the two call sites. ✓
Summary
The incremental diff is clean. The scanner suspension fix and the IPv6 test coverage are the meaningful changes on the tracked concern list. Three non-blocking items (Cargo.toml, CONNECT_TIMEOUT, WebSocket direct-mode test) remain; none of them constitute a merge blocker given the current scope of the PR.
The reason will be displayed to describe this comment to others. Learn more.
Follow-up pass: trigger head 5a8f352 is 4 commits behind the previously reviewed 5ae51eb — zero incremental diff. No new findings. Both must-fix blockers are resolved; 4 notables remain open.
Prior-issue status
✅ Fixed — issue #1: Android padding accumulates on each WebView reload (ShieldedPlatformPlugin.kt)
Fixed across two stages before and within the range 5a8f352…5ae51eb:
Accumulation (ShieldedPlatformPlugin.kt:43): private val baseInsets = WeakHashMap<View, Insets>() with getOrPut captures the original container padding exactly once per container instance; successive load() calls read the same baseline rather than re-capturing an already-mutated value.
Inset consumption (ShieldedPlatformPlugin.kt:65): WindowInsetsCompat.Builder(insets).setInsets(handledTypes, Insets.NONE).build() now correctly signals to child views that all system-bar / cutout edges have been consumed. The 5a8f352 state still returned Insets.of(leftInset, topInset, rightInset, bottomInset) here; the Insets.NONE change landed in the subsequent commits already reviewed under 5ae51eb.
Physical lock → unlock smoke test on Android is still listed as pending in the PR description.
✅ Fixed — issue #2: Stale torHealth closure makes the generationAfter fence a no-op (NativeWallet.tsx)
The generationAfter: torHealth.status.generation parameter (the stale-closure path) is gone. The call at NativeWallet.tsx:81–85 passes {mode: selectedMode.current, current: generationGuard} to openNativeVault. generationGuard is a fresh closure built inside open; it reads healthExpired.current, which is set to true at line 152 when a status update arrives with a newer generation while the vault is opening. expected.generation is undefined, so openNativeVault's generation-equality branch (expected.generation !== undefined && ...) is correctly bypassed; the expected.current() and outer generationGuard checks replace it with live-ref semantics.
⏳ Still open (notable) — issue #3: experimental-api arti feature undocumented
No change. Cargo.toml still enables arti-client/experimental-api to reach wait_for_stop(). The specific method and stabilisation tracking remain undocumented. No action required to merge; worth a follow-up comment so the next pin-bump has a checklist item.
⏳ Still open (notable) — issue #4: CONNECT_TIMEOUT = 90s long for mobile (direct.rs:12)
No change. Duration::from_secs(90) still holds the retirement token for up to 90 s, blocking any subsequent mode switch within the 10 s drain window. The common lossy-mobile failure path remains unaddressed. No action required to merge; worth a named constant with an explanatory comment, or a tighter per-platform value.
⏳ Still open (notable) — issue #5: IPv6 2001:0200::/23 passes public_address() without explanation (direct.rs)
Partial improvement: 2001:2::1 (2001:2::/48, IANA Benchmarking) is now correctly rejected and test-covered. 2001:0200::/23 (IANA Protocol Assignments) is still allowed and now explicitly asserted as public_address() returning true at direct.rs:162–163 — without a comment explaining the IANA allocation table reasoning. Low practical risk; a one-line comment linking to the IANA allocation table is enough.
⏳ Still open (notable) — issue #6: WebSocket direct-mode path has no dedicated test (wire.rs)
No change. socket_inner calls lease.connect(host) which propagates the direct-mode error, but there is still no test that exercises the WebSocket path in direct mode specifically.
Overall
Both blockers are cleared. The four remaining items are non-blocking follow-ups. No new issues introduced in the incremental range.

Stale catchup trigger — range already reviewed. 2 blockers resolved; 4 non-blocking items remain open.
This trigger presents 5a8f352...5ae51eb as new work, but commit 5ae51eb was already reviewed in the pass submitted 2026-11-08T14:01:48Z (review 5818170597), and the trigger mismatch was confirmed in the subsequent pass at 14:15:22Z (review 5818214607). The four commits in this range are:

6c75c940 — docs/NATIVE.md (+4/-4). Not explicitly called out in prior passes. The changes accurately reflect the new behaviour: Tor is now "default" rather than "required", direct mode is described with appropriate exposure caveats ("exposes the network address and DNS lookups"), and the same-mode resume / generation-bound provider lifecycle is correctly stated. No documentation makes a false privacy claim. No concerns.
Prior-issue status (complete)
Issue 1 — Android padding accumulates on WebView reload (ShieldedPlatformPlugin.kt)
Issue 2 — Stale torHealth closure makes generationAfter fence a no-op (NativeWallet.tsx)
Fixed (bee7585 / later commits). generationAfter parameter removed; replaced with live-ref generationGuard closure that reads healthExpired.current, which is set on every incoming status update. No stale capture.
Issue 3 — experimental-api arti feature undocumented (src-tauri/Cargo.toml)
Still open.arti-client/experimental-api to reach wait_for_stop() remains undocumented. No action required to merge; a comment in Cargo.toml naming the method and linking to the stabilisation issue/PR would protect the next pin-bump.
Issue 4 — CONNECT_TIMEOUT = 90s long for mobile (src-tauri/src/transport/direct.rs:12)
Still open.Duration::from_secs(90) holds the retirement token for up to 90 s, blocking mode switches within the 10 s drain window. Common failure path on lossy mobile. No action required to merge; a named constant with an explanatory comment, or a tighter value, would help.
Issue 5 — IPv6 2001:0200::/23 passes public_address() without explanation (direct.rs)
Still open (partially addressed by test coverage in 5ae51eb).2001:0200::1 is now explicitly asserted as dialable at direct.rs:162–163, confirming the exclusion logic is intentional and correct. The test closes the coverage gap. A one-line comment in public_address() linking to the IANA allocation table would still help the next reader understand why b >= 0x0200 within 0x2001 is globally routable.
Issue 6 — WebSocket direct-mode path has no dedicated test (src-tauri/src/transport/wire.rs)
Still open.socket_inner calls lease.connect(host) and inherits the direct-mode error propagation, but no test exercises the WebSocket path specifically in direct mode. Non-blocking; the same error gate is covered by the HTTP test, and the WebSocket path is structurally identical.
No new findings. Both blockers cleared. Issues 3–6 remain non-blocking follow-ups.

Android could leave the header under system bars, keep Unified receive waiting on unrelated HD scans, and show onboarding again after a brief background visit. This keeps the existing wallet visible and inert while reconnecting, then rebuilds its generation-bound providers with the same storage. Lock and network-mode changes still retire the old session. Delayed starts and vault reads cannot publish after suspension, and a changed vault secret fails closed.
Tor starts by default and creation/restore wait for readiness. Direct mode is an explicit, confirmed choice for the current app session. Healthy Arti clients and their directory cache are reused; the wallet module loads alongside connection startup. Direct TCP attempts are bounded, expire stalled addresses, refill slots, retain the first success, and close losing attempts before retirement completes.
Unified, Shielded and Arkade receive now share an exact-sats input and produce BIP21 links that round-trip through the send decoder. Raw invalid input stays visible with an error instead of silently changing the amount or falling back to an address-only QR. Missing or restore-masked addresses cannot become amount QRs, and Unified links normalize LNURL values to lowercase. Invoice limits load when the disclosure opens; unknown or out-of-range limits prevent invoice creation, and stale limit reads cannot overwrite newer results.
Unified startup exposes recovery after failure; retries that reload wait for tracked background actions, with the same 30-minute UI timeout as ordinary payments. That timeout does not cancel or complete the underlying payment or release its journaled input reservations. Balance failures have recoverable status rather than an unexplained indefinite spinner. Suspension closes the scanner and prevents reopening while reconnecting. Android insets use consistent window coordinates, restore baseline padding when insets shrink, and consume handled system-bar/cutout insets before WebView forwarding while retaining IME updates.
The shared web/native wallet gets a shield-and-ripple entrance, skipped on brief native resume and with reduced motion. Onboarding privacy opens upward inside the viewport, while the central stage remains scrollable on short screens.
Validation:
5ae51eb: 1,393 passed, zero failed/skipped. TypeScript checking passes. The SDK-handle regression proves that the UI timeout does not cancel or complete a pending payment.IsTor=trueboth before and after resume; before-open cancellation, in-flight pause and stale-generation rejection passed. Measured process starts ranged from 3.0 to 15.6 seconds across fresh/cached runs; in-process resume measured below 1 ms, with fresh isolated requests still taking several seconds. These are observations, not latency guarantees.5ae51ebpasses native CI for Windows, Linux, universal macOS, Android and unsigned iOS packages, plus Checks CI. Both full CI test runs pass; the PR-triggered log records 1,393 passing tests with zero failures/skips. Arkana's current-head review reports no blocking findings, and independent lifecycle/receive reviews found no remaining material issue. All review threads are resolved. CodeRabbit's current-head review was rate-limited; its success context is not fresh review approval, and the earlier actionable findings were addressed with focused regressions and rendered checks.Physical Android status-bar/cutout/keyboard behavior, native foreground rendering, and funded payments remain unverified. No funds were moved, and the real wallet seed/app data were not read or changed by the fixture.
