fix: base-branch follow-ups — funding gate height rule, replay wake lock, bind-heal lifetime, flaky tests - #1632

Conversation
The shared spend gate (wallet->shielded and SDK L1 sends) opened on scanCaughtUpToTip, which since 2026-09-21 also accepts the iOS aggregate rule: a filter shortfall of up to 0.3% of chain height (~4,600 blocks on testnet). The pipeline-lag veto cannot see that gap while the wallet cursor is unknown (0), so a spend could open with thousands of blocks unscanned. When the cursor is known, the §34 stall parks it with the filter cursor and the veto closed the gate anyway, so requiring the height rule only closes the unsafe case. The gap is measured against the highest tip the snapshot knows (max(bestKnownTipHeight, filterTarget)): dash-spv restores the header target from the last peer report at engine start, which can sit below the stored header tip the filter target already names. The display predicate is unchanged. Raised by CodeRabbit on #1584. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Post-cutover a replay keeps the blockchain service alive and holds a PARTIAL_WAKE_LOCK with no timeout. While offline (NETWORK impediment) or once the filter-stall watchdog has spent its restarts on a wedge, the replay cannot move, yet the CPU stayed awake for as long as it was stuck. The service still stays up (stopping it re-walks from the durable watermark and loops through the replay restart alarm); only the lock is released. FilterStallWatchdogDecider.standingDown marks the wedge, cleared when the cursor moves, events resume, the scan is no longer behind, or the engine stops. TIME_TICK is not delivered while the CPU sleeps, so the impediment update re-acquires the lock when the replay is due again. Acquire and release run under one guard and re-check the inputs, and onDestroy retires the lock so a late network-callback coroutine cannot re-acquire it after the teardown's release. Raised by CodeRabbit on #1584. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
kickSdkEngines checked serviceLifetime once, after the bind join. A shutdown landing after startIfEnabled() returned (arm() does not suspend, so cancelling the kick cannot stop it) let arm() run after the shutdown's cancel; that waiter survived the teardown and started L1 on a later bind heal with no foreground service. The kick now arms only while its lifetime is current and passes a stillCurrent predicate that the waiter re-reads after the heal. arm and cancel are serialized and the shared job fields are volatile. Raised by CodeRabbit on #1584. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
PlatformSyncEngineRestartTest.resume_isRearmableAcrossRepeatedStopRestartCycles went stale within #1568: a later commit there made stopSdkEngines() cancel a kick still waiting on its bind, so three back-to-back cycles collapse into one or two starts. Each cycle now waits for its own start, and a new test pins the cancel-on-stop behaviour. Six CutoverUiDataServiceTest cases failed depending on timing: since #1570 refreshNativeSplit reads the receive address via withContext(Dispatchers.IO), a real-thread hop inside every runTest refresh, so runCurrent() returned before the refresh published. The read's dispatcher is now injectable (default IO); the test builder passes the runTest dispatcher, and the two parked-read rollback tests keep the real IO hop they gate on.

Final validation — Phase 1 + Phase 2
Verified one in-scope replay recovery regression: clearing the filter-wedge state does not restore wake-lock ownership, so runnable synchronization can suspend again before the next minute tick. Current CI build and check jobs pass, and the supplied base-drift evidence reports no merge conflicts. Validation was static; no local builds or tests were run.

- [BLOCKING] wallet/src/de/schildbach/wallet/service/BlockchainServiceImpl.kt:3841-3843: Reacquire the replay wake lock when the filter wedge clears
This is the only event-driven call to reacquireReplayWakeLockIfDue(), and it runs for network/security impediment updates, not watchdog recovery. After the watchdog exhausts its restart budget, the minute tick releases the replay lock. If the engine subsequently resumes progress while still behind the tip, FilterStallWatchdogDecider.onCheck() clears standingDown, but neither that transition nor the blockchain-state observer reacquires the lock. With no engine-start or durable-save hold active, the replay remains unprotected until another minute tick or connectivity callback. Observing recovery while awake does not keep the CPU awake until that tick: a screen-off device can suspend again, and ACTION_TIME_TICK does not wake it, delaying runnable synchronization until an unrelated wakeup. Notify BlockchainServiceImpl when the wedge clears and reevaluate acquisition immediately, retaining the teardown retirement guard. Add a regression case covering exhaustion, lock release, and recovery without a network change; the existing predicate and decider tests do not cover this connection.
Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Durable balance seed still accepts aggregate completion with an unknown cursor — CutoverUiDataService persists LAST_TOTAL_BALANCE when the display aggregate predicate reports synced and the pipeline is not lagging. An unknown wallet cursor does not count as lagging, so this can persist a partial balance while filters remain materially behind the tip, then reuse that figure on subsequent launches. This is a concrete persistence follow-up, but the behavior predates this PR and is not changed by its receive-address dispatcher injection or spend-gate tightening.
- Follow-up: Track a separate issue to require stronger scan-completion evidence before replacing the durable last-known balance.
Once the filter-stall watchdog had spent its restarts, the minute tick released the replay wake lock. Only the tick or an impediment change re-acquired it, and ACTION_TIME_TICK is not delivered while the CPU sleeps, so a replay that recovered on its own ran unprotected until an unrelated wakeup. The replay hold moves into ReplayWakeLock. It keeps the guard, the teardown retirement, the re-check before release and the owner-only teardown release. FilterStallWatchdogDecider.standingDown is now backed by a StateFlow, and the blockchain service re-checks the lock the moment it clears. The clear is also event-driven: the progress feed (a filter cursor off the stand-down height) and the wallet-event tap end the stand-down at once, instead of waiting for the watchdog's one-minute delay, which also stalls while asleep. The spend gate's pipeline-lag veto now measures against the same highest-known tip as the height rule. headerTarget alone can sit below the stored tip after a restart. Regression test: ReplayWakeLockTest drives the real decider through exhaustion, release and recovery with no tick or network change. Raised by PastaClaw and CodeRabbit on #1632.

Re-review — Final validation — Phase 1 + Phase 2
The funding-gate tightening and bind-heal lifetime changes are supported by the surrounding code, and the prior wedge-recovery finding is fixed. One blocking gap remains: a service created while already offline can still acquire and retain the replay's no-timeout wake lock. Current build and check jobs pass; this verification was static and did not run local builds or tests.

- [BLOCKING] wallet/src/de/schildbach/wallet/service/BlockchainServiceImpl.kt:2477-2482: Initialize connectivity before relying on the NETWORK impediment
The offline-release rule does not handle a service created while the device is already offline. The service's `impediments` set starts empty, and network registration at lines 2989–2993 does not initialize it from current connectivity. With no matching network, passive `registerNetworkCallback()` registration produces no initial `onAvailable`, `onCapabilitiesChanged`, or `onLost`; `onUnavailable()` is a callback for an unfulfilled `requestNetwork()`, not this registration. Consequently, a successfully bound SDK wallet with a persisted replay still in progress is treated as online here and in `replayWakeLockDue()`, allowing the no-timeout partial wake lock to remain held despite airplane mode. The SDK-derived NETWORK stall bit does not fix this: `BlockchainStateDataProvider` composes it into the persisted state separately and never writes it into this service's set. This leaves the PR's stated offline-release fix ineffective for cold or background starts while already offline. Initialize connectivity before replay acquisition, with ordering that cannot overwrite newer callback updates, and use that initialized state in both hold decisions. Add a regression for service creation while already offline, rather than only an online-to-offline transition.
…tart The blockchain service's NETWORK impediment was only ever set by its network callback, and a passive registerNetworkCallback reports nothing while no network matches. A service created while already offline therefore read as online, and a replay persisted from the previous session held the no-timeout replay wake lock in airplane mode. onCreate now seeds the impediment from the default network's capabilities (internet + validated, the callback's own rule) before it registers the callback, so every callback update overrides the seed. An unreadable connectivity state answers "usable", the old assumption. Raised by PastaClaw on #1632. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The minute tick computed the replay's hold decision inline, while ReplayWakeLock re-read replayWakeLockDue() before releasing. They agreed, but a later edit to one copy alone could leave the tick asking to release while the re-check still read "due", refusing the release on every tick and keeping the no-timeout lock held. The tick now uses replayWakeLockDue() too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Re-review — Final validation — Phase 1 + Phase 2
Both prior replay wake-lock findings are fixed at the reviewed head. One bind-heal lifecycle race remains: an obsolete startup kick can replace the current service's valid waiter and leave L1 stopped after binding heals. Current build and check jobs pass; verification was static, with no local builds or tests run.

- [BLOCKING] wallet/src/de/schildbach/wallet/service/platform/sdk/BindHealL1Starter.kt:77-78: Reject an obsolete arm before replacing the current waiter
An old startup kick can pass the lifetime check in PlatformSyncService.kt:604, be descheduled while shutdown and a new service startup complete, then enter arm() after the new lifetime has installed its valid waiter. This unconditionally cancels that valid waiter and replaces it with an obsolete one. Cancelling the old startup kick does not prevent this non-suspending call from launching a sibling job on the independent syncScope; the identity-less shutdown path also leaves that scope alive. When binding heals, the replacement waiter's new lifetime check rejects the start, leaving the running service without an L1 engine or a valid bind-heal waiter. Check stillCurrent() inside the synchronized arm method before cancelling or replacing job, and retain the post-heal check. Add a regression that arms a current-lifetime waiter, submits an obsolete arm, then heals the bind and verifies that L1 starts.
…ent bind-heal waiter A startup kick passes its lifetime check, then shutdown and the next service start can complete before it reaches arm(). arm() cancelled the waiter the new lifetime had armed and installed one that refuses to start, leaving the running service with no L1 engine and nothing waiting to start it. The kick's cancel() on a successful start had the same hole. arm() now checks stillCurrent first, under the monitor, and ignores an obsolete arm; the kick's cancel takes the same check (shutdown's cancel stays unconditional). The waiter still re-checks after the heal. Raised by PastaClaw on #1632. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The start-up connectivity read ran before registerNetworkCallback. A network lost in between was never reported (nothing matched any more), so the service read as online and a persisted replay could take the no-timeout wake lock offline. The read now runs after registration. ImpedimentGate keeps it from overwriting the callback: every callback update bumps a counter under one lock, and the seed marks the service offline only if no update has landed since the token taken just before registering. The same lock now serializes every change to the impediment set (the network callbacks on IO, the keystore observer on main), and the callbacks run one at a time in delivery order, so an onLost can no longer be processed before the onAvailable it follows. Raised by CodeRabbit on #1632. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
… a wedge flip ReplayWakeLock observed the filter wedge as a StateFlow<Boolean>. A collector slow to run can miss intermediate StateFlow values, so clear → re-wedge → clear arrived as the "not wedged" it had already seen, while the minute tick released the lock during the re-wedge. Nothing re-took it, and a screen-off replay could stay asleep. FilterStallWatchdogDecider now counts its true → false transitions (standDownClears, updated with the flag under one lock), and the service observes that count (L1ShadowSyncService.filterScanWedgeClears). A count the observer has not seen always means a clear happened, so it re-checks; reacquireIfDue reads the current state, so a clear already followed by a new wedge acquires nothing. The baseline is read when observation starts, not on the collector's first run. The teardown retirement guard is unchanged; no polling. Regression: ReplayWakeLockTest runs the clear → re-wedge → clear sequence with the collector held back on a test dispatcher and asserts the lock is re-taken once it runs; plus a clear superseded by a new wedge, and a clear between registration and the collector's first run.

Re-review — Final validation — Phase 1 + Phase 2
Reviewed the complete diff at 0a9b03f and verified that all three prior findings are fixed. One blocking lifecycle defect remains: a restarted engine can inherit an expired stall timer and prematurely lose its replay wake lock. Validation was static only; the current check job and CodeRabbit pass, while the build job remains pending.

- [BLOCKING] wallet/src/de/schildbach/wallet/service/platform/sdk/L1ShadowSyncService.kt:1378-1380: Re-baseline stall timing when the engine stops
Clearing `standingDown` leaves `lastHeight` and `lastAdvanceMs` from the stopped engine intact. After exhaustion at height H, stop and restart the engine in the same process with its durable watermark also at H, still more than one batch behind the target. `stopInternal()` resets `lastWalletEventMs` to zero, but nothing resets the decider's timing baseline. If the new run has not advanced or emitted wallet events before its first one-minute watchdog check, that check skips the height-change baseline and immediately sets `standingDown` again through the exhausted-budget branch. The next service tick can therefore release the new run's replay wake lock after approximately one minute rather than giving it the configured stall window, allowing an ordinary screen-off startup pause to suspend synchronization. Re-baseline the per-run stall observation when the engine stops while retaining the process-wide restart budget. Extend the regression through exhaustion, stop, long downtime, restart at the same height, and the first subsequent watchdog check; the current test ends immediately after checking that stop cleared the flag.
Out-of-scope follow-up suggestions (2)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Prevent funding while the SDK is only CONNECTING or the wallet cursor is unknown — The funding helper still permits a CONNECTING snapshot with sufficient retained height evidence, and an unknown committed wallet cursor does not veto an otherwise caught-up scan. These are concrete spend-readiness gaps already present on the base; this PR adds height vetoes without introducing or widening those acceptance paths.
- Follow-up: Track a separate readiness-policy change covering disconnected snapshots and unknown committed-pipeline state, including recovery behavior that avoids permanently blocking new wallets.
- Harden durable balance-seed persistence against aggregate and unknown-cursor progress — CutoverUiDataService still permits durable balance persistence from the display's aggregate completion signal when the committed cursor is unknown and therefore does not report pipeline lag. This can preserve an incomplete balance across launches. That persistence policy predates this PR and is unchanged by its receive-refresh dispatcher injection.
- Follow-up: Track a separate fix requiring sufficient scan-height and committed-pipeline evidence before persisting LAST_TOTAL_BALANCE.

On CodeRabbit's outside-diff comment, "Carry the engine-stop generation into the bind-heal start" ( The bare |
onEngineStopped() cleared the stand-down flag but kept the stopped run's stall timing (lastHeight / lastAdvanceMs). A run restarted at the height the watchdog stood down at was then read as "same cursor, still since long ago" on its first check and stood down again within a minute, so the replay lost its wake lock with none of the stall window spent. Drop the per-run timing on stop (the restart budget stays per process), and synchronize onEngineStopped() with onCheck() so a check still in flight on the cancelled watchdog cannot write the old baseline back.

Re-review — Final validation — Phase 1 + Phase 2
The change fixes the four prior findings, but three blocking concurrency and lifecycle defects remain. Bind-heal startup can still occur after service teardown, the replay wake-lock decision treats any validated secondary network as sufficient, and wake-lock reacquisition can use a stale replay-eligibility result. The check job is green; the build job was still in progress in the supplied CI snapshot.

- [BLOCKING] wallet/src/de/schildbach/wallet/service/BlockchainServiceImpl.kt:3000-3013: Base the NETWORK impediment on the default route
The service registers a generic INTERNET + VALIDATED `NetworkRequest`, so `onAvailable()` can clear `Impediment.NETWORK` for a validated secondary network even when the default route used by ordinary service traffic is unusable. The replay wake-lock predicate consumes this impediment directly, so a persisted replay can retain its no-timeout CPU hold while the actual route is offline. The inverse transition is also unsafe: `onCapabilitiesChanged()` adds NETWORK when one matching network becomes invalid without reconciling `availableNetworks`, so another usable matching network can be present while the impediment remains set. Observe the default network, or update the impediment from the complete currently usable network set.

`reacquireIfDue()` evaluates `replayDue()` before entering the synchronization used by `hold()`, and `hold(true)` does not re-evaluate that predicate. A recovery event can therefore observe the replay as due, then a concurrent network loss or wedge can make it unable to progress, and the stale call can still acquire the no-timeout lock. If no later tick or event runs while the CPU sleeps, the lock remains held despite the replay being stalled. Perform the due check and acquisition under the same guarded path, while retaining the retirement check.

- Fail closed when the wallet cursor is unknown — The funding gate still permits a spend when
walletSyncedHeight == 0if the filter scan is at the tip andblockPipelineLaggingis false. A failed durable-watermark seed or the interval before the first wallet event can therefore allow a send or shield to use an incomplete ledger. This predates the current diff and is disclosed as a separate follow-up, so it should be tracked independently rather than expanded into this change.- Follow-up: Create a separate tracked issue or maintainer-requested PR covering seed failure and the pre-first-event window.
…nd-heal stop generation Three review blockers on #1632: - NETWORK impediment from the default network. The callback was registered for any network with internet + validated, so a validated secondary network cleared the impediment while the default route was unusable, and one matching network losing validation set it while another was up. It is now a default-network callback (DefaultNetworkTracker): offline unless the default network has internet and is validated. A loss of a former default is ignored in either delivery order. - Replay wake lock rechecks under one monitor. reacquireIfDue() read the decision outside the lock's monitor and could only acquire, so a recovery that read "due" just before a network loss kept the no-timeout lock offline until the next tick. tick() and every event now run recheck(), which reads tickHolds || replayDue() and acquires or releases under the monitor, so the loss's own recheck releases. The tick records the holds only it can see (engine start, durable save). - Bind-heal start carries the engine stop generation. The waiter samples it before its lifetime/teardown checks and passes it to startIfEnabled(expectedExternalStopGeneration), so a shutdown that passes the checks and finishes the engine stop before the start keeps L1 down.

Re-review — Final validation — Phase 1 + Phase 2
The replay wake-lock, default-network tracking, bind-heal lifetime, watchdog reset, and connectivity-seeding fixes are addressed at the reviewed head. Two blocking defects remain in the modified L1 funding gate: CONNECTING snapshots can pass using stale heights, and an unknown wallet pipeline cursor is treated as safe. The code check passed; the build check was still in progress at the supplied snapshot.

- [BLOCKING] wallet/src/de/schildbach/wallet/service/platform/sdk/ShieldedBalanceServiceImpl.kt:254-258: Reject CONNECTING snapshots in the funding gate
The gate rejects IDLE and ERROR but admits CONNECTING. `WAITING_FOR_CONNECTIONS` maps to CONNECTING while the SDK progress object can retain the previous header, filter, and wallet heights. After a route loss or restart, those stale heights can satisfy `scanCaughtUpToTip` and the new height checks even though the engine cannot process transactions, allowing wallet-to-shielded or SDK L1 spending while synchronization is offline. CONNECTING must fail closed as a non-running phase.
- [BLOCKING] wallet/src/de/schildbach/wallet/service/platform/sdk/ShieldedBalanceServiceImpl.kt:289-292: Fail closed when the wallet pipeline cursor is unknown
The pipeline-lag veto is applied only when `walletSyncedHeight > 0`. A snapshot can therefore have filters at the highest known tip while the wallet cursor is still unknown because no durable seed or `SyncHeightAdvanced` event has supplied evidence that matched blocks were processed. The gate then opens and a spend can be built from a stale UTXO view, potentially selecting an output already spent or omitting a newly received transaction. Unknown must not count as proof that the pipeline is drained; the gate should remain closed until a positive cursor is available and within tolerance.
Out-of-scope follow-up suggestions (2)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Recheck the funding gate before deferred broadcast —
broadcastDeferredPaymentbroadcasts an already-prepared reserved payment without re-evaluating current synchronization or funding readiness. Synchronization can regress while the payment is deferred, leaving the later broadcast based on stale evidence. This path is unchanged by the PR and is a separate follow-up from the direct funding gate modified here.- Follow-up: Track a separate change to define the safe pre-broadcast revalidation while preserving reservation ownership and ambiguous-outcome handling.
- Fail closed on an unknown cursor in the durable balance-seed gate —
CutoverUiDataServicestill defaults the pipeline-lag signal to non-lagging when the wallet cursor is unknown, so a durable last-known balance can be persisted while matched blocks are still being processed. This is a concrete funds-safety follow-up, but the PR only changes the refresh dispatcher in that file and does not modify the durable persist predicate.- Follow-up: Track a separate change that distinguishes an unknown pipeline cursor from a positively drained cursor before persisting the durable balance seed.
WAITING_FOR_CONNECTIONS maps to CONNECTING, and after a route loss or a restart that snapshot can keep the previous session's heights, which pass every height rule while the engine cannot see a new block. The gate admitted it, so a wallet->shielded transfer or an SDK L1 send could open with sync offline. CONNECTING now fails closed like IDLE; the display already reads it as offline. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The pipeline-lag veto only applied when walletSyncedHeight > 0, so a
snapshot with filters at the tip and no cursor evidence opened a spend
over a UTXO view nothing proved current. An unknown cursor now closes the
gate ("SDK L1 wallet scan cursor is not known yet").
It cannot wedge a synced wallet: the cursor is seeded at engine start from
the SDK's durable WalletEntity.syncedHeight, and dash-spv emits
SyncHeightAdvanced for every wallet each committed filter batch covered,
matches or not. On the emulator a fresh testnet wallet reported a
non-zero cursor from its first batch, and its restart was seeded from the
durable value.

Re-review — Final validation — Phase 1 + Phase 2
The PR fixes all nine prior blocking findings, including the funding-gate, wake-lock, default-network, bind-heal, watchdog, and startup-connectivity issues. One new blocking race remains in the default-network tracker: a delayed capability update from a former default can restore the NETWORK impediment after a successor becomes current, leaving synchronization offline. The code check passed; the build check was still in progress in the supplied CI snapshot.

- [BLOCKING] wallet/src/de/schildbach/wallet/service/NetworkAvailability.kt:74-76: Ignore capability updates from a former default network
`onCapabilitiesChanged()` unconditionally replaces `current` with the callback's network. During a default-network handoff, the successor's `onAvailable()` can make network B current while a queued capability update for former network A is still delivered; that update then makes A current again and can set `Impediment.NETWORK`. If A's later `onLost()` is processed while A is incorrectly current, it leaves the tracker offline even though B remains usable. Because no later callback is guaranteed, the SDK replay can remain without its wake lock and synchronization can stay blocked until another unrelated network event. Capability updates should be ignored unless they refer to the currently tracked default network.
…fault DefaultNetworkTracker.onCapabilitiesChanged made whatever network it was told about the current default. A late update for the former default, delivered after its successor's onAvailable, took it back (and could mark the device offline), and that network's later onLost then matched and left the tracker offline with the successor still up. Only onAvailable now changes the default; an update for any other network returns no verdict, and the callback updates the impediment and re-checks only when there is one.

Re-review — Final validation — Phase 1 + Phase 2
The funding gate, default-network tracking, wake-lock serialization, bind-heal lifetime checks, connectivity initialization, and watchdog restart handling are correctly fixed at this head. One remaining concurrency edge lets a stale progress or wallet-event callback clear a newer watchdog stand-down and briefly reacquire the replay wake lock; the check job passed, while the build job is still in progress.

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Recheck synchronization before broadcasting deferred payments —
broadcastDeferredPayment()consumes and broadcasts an already-built reservation without re-evaluating synchronization freshness. This is a concrete funds-safety follow-up, but the reviewed changes do not modify that deferred-payment contract or broadcast path.- Follow-up: Track separately in a maintainer-requested issue or PR defining deferred-payment reservation freshness and acknowledgement-time policy.
- Close the durable balance-seed persistence gate on unknown wallet cursors — The durable balance-seed path can still persist a snapshot without the same positive wallet-cursor evidence now required by the funding gate. This can preserve a stale launch balance, but it is a pre-existing adjacent path not changed by this PR.
- Follow-up: Track separately and require a known, sufficiently current wallet cursor before persisting the launch balance seed.
- Upgrade the pinned SDK for current testnet special-transaction decoding — The pinned int30 SDK/rust-dashcore version cannot decode some current testnet Core v24 special transactions, which can leave synchronization in ERROR. The funding gate fails closed in that state, so this affects availability rather than authorization and is outside this PR.
- Follow-up: Track the int31 SDK/rust-dashcore upgrade and add regression coverage for Core v24 special-transaction decoding.
…l decisions onFilterProgress() and onWalletEvent() read the stand-down and cleared it outside the monitor onCheck() holds. A callback that read an old stand-down could clear a newer one a check had just decided, and the clear re-took the replay wake lock on a wedged engine until the next check. Both are now synchronized on the decider, so the read and the clear judge the state the last decision left. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Re-review — Final validation — Phase 1 + Phase 2
The current head fixes all 11 previously verified findings, but a new blocking startup connectivity race remains. ImpedimentGate counts callback invocations that produce no network verdict, allowing a no-op callback to suppress the offline seed and leave an offline replay without the NETWORK impediment; the build check is still in progress while the static check succeeded.

`networkCallbackUpdate` increments `networkCallbackUpdates` for every callback invocation, including callbacks whose tracker result is `null` and therefore do not update the NETWORK verdict. During registration or a default-network handoff, a capability/loss event for a former default or an `onAvailable` whose capabilities cannot be read can increment the counter without adding or removing `Impediment.NETWORK`. If the subsequent connectivity read reports no usable network, `seedOffline()` sees the counter change and skips seeding, leaving the service apparently online. A persisted replay can then retain the no-timeout wake lock while offline because its due predicate sees no NETWORK impediment. Count only callback results that produced an actual verdict, while continuing to count `onUnavailable()` because it directly applies the offline verdict.

- Fail closed before persisting the durable balance seed when the wallet cursor is unknown —
CutoverUiDataServicestill permitsLAST_TOTAL_BALANCEpersistence when the aggregate sync predicate says the wallet is synced but the wallet pipeline cursor is unknown. That can persist a partial balance as the next-launch seed. The persistence gate is adjacent to this PR's funding-gate work but is pre-existing and not changed by this diff.- Follow-up: Track separately and require a known, sufficiently current wallet cursor before persisting the durable balance seed.
- Recheck the funding gate before broadcasting deferred payments —
broadcastDeferredPaymentconsumes an already signed and reserved transaction without re-evaluating synchronization readiness after the merchant acknowledgement. If synchronization becomes stale while the acknowledgement is pending, the deferred transaction can still be broadcast. This is a pre-existing build/broadcast reservation contract outside the changed implementation.- Follow-up: Track separately and define the required revalidation, reservation, and ambiguous-outcome behavior for deferred broadcasts.
…seed
ImpedimentGate counted every network-callback update, including callbacks
the default-network tracker answered with no verdict (an onAvailable whose
capabilities could not be read, a loss of or update for a network that is
not the default). One of those landing during registration skipped the
start-up seed, and a service with no usable network read as online.
networkCallbackUpdate now takes the verdict its block applies and counts
only a non-null one; onUnavailable returns its offline verdict, and the
teardown clear goes through update {}.

Re-review — Final validation — Phase 1 + Phase 2
Static review of exact head 0445d94 found no in-scope defects. The funding gate, replay wake-lock lifecycle, default-network tracking, watchdog synchronization, connectivity seeding, and bind-heal lifetime protections are implemented consistently, and all 12 prior findings are fixed. The check CI job succeeded; the build job was still in progress at the supplied snapshot.

- Align durable balance-seed persistence with the strengthened funding evidence — CutoverUiDataService still allows durable LAST_TOTAL_BALANCE persistence when the display-level sync predicate is satisfied, without requiring a known wallet cursor or the height evidence enforced by evaluateWalletFundingGate. This can preserve a partial balance as the next launch's seed, but the path predates this PR and is not changed by the reviewed diff.
- Follow-up: Create a separate wallet-state integrity change that gives durable balance persistence an explicit known-cursor and height/pipeline evidence gate while preserving the less restrictive display predicate.
- Upgrade the pinned SDK for testnet special-transaction decoding — The pinned SDK revision reportedly cannot decode testnet Core v24 special-transaction payloads, which can leave synchronization stopped short of the tip and keep the funding gate closed. This is an upstream dependency compatibility issue, not a defect introduced by this PR.
- Follow-up: Track and implement the SDK revision upgrade containing the rust-dashcore decoding fixes, with mainnet and testnet network-separation regression coverage.

Re the QA run above, D-1632-01 (the replay wake lock is released by the minute tick, not by the network event): fixed in a9dd29c. The diagnosis was right.
The tick records with One behaviour to note: if the SDK really is still saving the scan when the network drops (durable height more than 10,000 blocks behind and still moving), the lock stays held. That's local disk work that continues offline, as before. It's now decided from the live state at the moment of the loss instead of the last tick's. Regression: |

Re-review — Final validation — Phase 1 + Phase 2
The reviewed head fixes all twelve prior findings, and the supplied build/check CI jobs succeeded for the exact head. Two concrete funding-safety follow-ups remain in related code: the durable balance seed can still persist an aggregate-only snapshot with an unknown cursor, and deferred-payment broadcast does not revalidate synchronization evidence; both lack tracking links, so this warrants a non-blocking comment.

🟡 Suggestion: Durable launch-seed persist keeps the aggregate/unknown-cursor gap
wallet/src/de/schildbach/wallet/service/platform/sdk/CutoverUiDataService.kt:4795-4796
The funding gate now explicitly rejects an unknown wallet cursor and requires the filter cursor to be near the highest known tip, but the durable launch-seed path still computes persist from synced && !lagging. synced comes from sdkL1ScanCaughtUp, whose aggregate rule can accept a filter scan thousands of blocks short, while lagging is false whenever walletSyncedHeight is 0. An aggregate-only snapshot with an unknown cursor can therefore persist a partial balance into LAST_TOTAL_BALANCE, poisoning subsequent launches with the same stale figure. Align this seed decision with the funding gate's positive height and cursor evidence, or extract a shared fail-closed predicate; at minimum, track this sibling issue before treating it as deferred.

wallet/src/de/schildbach/wallet/service/platform/sdk/SdkL1SendService.kt:1722-1733
buildDeferredPayment checks probeSendGate() before signing and reserving inputs, but broadcastDeferredPayment later consumes that reservation and broadcasts based only on the wallet remaining bound. If the preview/merchant-ack interval crosses a synchronization stall, route loss, CONNECTING state, or tip advance, the transaction is still submitted using funding evidence that the current gate would reject. This needs an explicit deferred-payment policy: revalidate before broadcast and safely release on failure, or define why the reservation makes the original gate decision authoritative and how stale evidence is handled. The PR documents this as a follow-up, but no tracking issue or PR is linked.

The funding gate now explicitly rejects an unknown wallet cursor and requires the filter cursor to be near the highest known tip, but the durable launch-seed path still computes `persist` from `synced && !lagging`. `synced` comes from `sdkL1ScanCaughtUp`, whose aggregate rule can accept a filter scan thousands of blocks short, while `lagging` is false whenever `walletSyncedHeight` is 0.

…ject map) (#1637) * chore(claude): /pre-review skill and an opt-in push gate (#1634) * chore(claude): /pre-review skill and an opt-in push gate thepastaclaw re-reviews the whole PR range on every pushed commit and approves only at zero findings, so each push with a finding we could have seen costs a round. The skill runs the bot's own model (GPT-6.1 Sol via the Codex CLI) with its public review prompts, fetched at run time from a pinned commit, over merge_base..HEAD; Claude then verifies each finding against the code and fixes the whole class of it. Verdicts are cached per commit in ~/.cache/prereview and count only for a range that covers the commit's merge base with the PR's base. The push gate is off unless a clone turns it on (prereview.sh --install, a pre-push hook copied into .git/hooks), so nobody needs the Codex CLI unless they opt in. From a terminal the hook runs a missing review; from a non-interactive shell it refuses and says to run /pre-review first. test_prereview.sh covers the gate with a fake codex. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(pre-review): how to give Codex access to ChatGPT The script only checks that Codex has a login; nothing said how to make one. README.md (and the script's header and error messages) now name the two ways: `codex login` with a ChatGPT plan (--device-auth without a browser), or an OpenAI API key in OPENAI_API_KEY (or stored with `codex login --with-api-key`), with the one-line check, the CLI version the model needs, and where a key must never go. The skill tells Claude never to ask for the key in the chat. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): no pinned prompts, no verdict; tests clean up and ignore the caller's env - With the pinned review prompts unreachable, the review used to fall back to this repository's guidance and cache a zero-count answer as clean, which the gate then trusted. A review by other rules must not stand in for the bot's: it now ends "not reviewed" (found by the skill's own pre-review of this change). - From CodeRabbit's review: every test run left its temporary repositories behind, and an inherited OPENAI_API_KEY (or PREREVIEW_BASE / PREREVIEW_TIMEOUT) changed what the cases test — with a key set, the logged-out case passed for the wrong reason. An EXIT trap removes the run's folder, and the variables are unset before the cases run. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): a verdict is for exactly its range; the API key codex exec reads From thepastaclaw's review of this PR: - A cached verdict was accepted when its base was any ancestor of the current merge base. That is not the same diff: a branch that undoes a change the base made after the reviewed base shows the undo in the current range and not in the reviewed one. The recorded base must now equal the current merge base; a base that moved means a new review. Regression test: master advances to the branch's first commit, the same tip goes stale, master back, clean again. - codex exec (0.163) reads an API key from CODEX_API_KEY; OPENAI_API_KEY alone is ignored, so the documented environment-only setup passed the check and then failed in Codex. The check accepts CODEX_API_KEY, copies OPENAI_API_KEY into it, and the docs name CODEX_API_KEY. - --status exits 0 when HEAD has no report; a blank line before the new CLAUDE.md heading. From this change's own pre-review (the skill, on itself, three rounds at effort high): - the hook and --status checked the merge base against the local copy of the base, so a base that moved on origin since the last fetch did not make a verdict stale: the base is fetched first, into its remote-tracking ref (a single-branch clone's plain fetch updates only FETCH_HEAD), and a fetch that fails refuses the push (the range is unknown) — unless the push only deletes; - GIT_DIR / GIT_WORK_TREE, which git exports to its hooks, reached the review's worktree and would have made git there resolve the checkout's HEAD: cleared at the top, as githooks(5) says; - a signal to the script did not reach the review it had started: the lock holder ran on and could publish a verdict after the cancellation. INT/TERM/HUP are forwarded to it, and it runs codex in the background so its trap fires at once, stops codex and cleans up; - the test harness went on after a failed cd and would have made its fixture commits in the caller's checkout: setup steps now abort the run; - the docs said the bot re-reviews the whole range on every push; its pinned policy reviews the whole range once and later pushes against the findings it carries forward. The whole-range pass here is this skill's choice, said so. - The review runs at reasoning effort high (PREREVIEW_EFFORT), the bot's own setting for this model; codex exec's default is lower, which is one reason it missed these. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(pre-review): the model's commands never see the reviewer's credentials From thepastaclaw's second review (security-auditor): codex's default shell_environment_policy hands the whole environment to every command the model runs, so a branch under review could make the reviewer run `printenv CODEX_API_KEY` and put the key in its answer, which this script prints and keeps. And its read-only sandbox lets those commands read the whole disk, ~/.codex/auth.json included, so a stored login was exposed the same way. Both confirmed on codex 0.163 with canary values: visible by default, gone with the changes below. The commands the model runs now get an explicit environment allowlist (include_only, applied last, so a `set` entry in the user's own codex config cannot bring a credential back), git pointed at an empty global config (the user's may carry a PAT in a url.insteadOf or an extraheader), a scratch folder of the review's own as TMPDIR (not the shared temp dirs, where another review keeps its files), and a permission profile instead of -s read-only (the two do not compose; a sandbox_mode in the user's config is fine — the session's default_permissions wins, checked): they may read the review's own --shared clone of the commit (not a linked worktree: codex resolves a linked worktree's project trust through the main checkout, and a trusted one would load the reviewed tree's .codex/config.toml), the object stores it borrows (alternates, recursively — a --shared or --reference checkout needs them), the pinned prompts and the minimal system paths. Codex's ways out of the sandbox are switched off and read back: the user's MCP servers by name with a complete entry (`-c mcp_servers={}` merges instead of clearing, and a partial `.enabled=false` for a server the desktop app provides breaks codex's config load), the implicit Apps connector, browser and computer use and web search through `features.*` and `web_search`. A copy of the login in a private CODEX_HOME is not the way either: codex rotates refresh tokens, and a copy left behind by a cancelled review would break the user's login. The clone carries the base as origin has it (its origin/<base> would be the checkout's stale local branch), and a verdict records that base tip: a base that moved on, even without changing the merge base, was never checked against the branch, so the verdict goes stale. codex older than 0.163.0 (no permission profiles) or a capability that does not read back as off make the review refuse. A failed removal of an earlier verdict is no longer ignored: removed, or emptied, or the review refuses and says the gate still trusts it. The prompt asks for a static review — the first real pass ran the test suite in the sandbox until the 25-minute cap. The report is scrubbed of the key's value, README prefers `codex login --with-api-key` over an environment variable, and --install and --uninstall refuse under a shared core.hooksPath: the gate is per clone. From CodeRabbit: "for every pushed commit" read as a review per commit; one review of merge_base..tip covers the commits in between. Reworded in SKILL.md, README.md and the header. From this change's own pre-review: - the lock's descriptor was inherited by every child that can outlive a cancelled review (git fetch and clone, curl, codex and its probes), so a stray one kept the commit locked after the cancellation: they all start without it, in the background with a wait so a signal reaches the trap at once even while a fetch or a probe stalls (probes write to files, never `$(…)`: a foreground subshell defers the trap), and cleanup and cancellation traps are set from the first step; tests cancel during a stalled fetch, a stalled probe, and with a timeout that does not kill the group; - the test harness inherited the caller's git configuration and git's environment overrides: with a global or GIT_CONFIG_COUNT-supplied core.hooksPath its --install and --uninstall would have written to, and deleted from, the caller's real hooks folder, and a GIT_INDEX_FILE would have taken the fixture's `git add`. All of it cleared for the run; - a push of several refs: a ref accepted against the base as fetched, then the next ref's own review fetches a base that moved meanwhile — every tip is checked once more at the end (the test calls the hook directly: git puts its exec path first in a hook's PATH, so a wrapper never reaches it); the cleanup tests look at the review's folder itself, not `git worktree list`; - the review tree was cloned and checked out with the user's git config in force: a relative core.hooksPath (.githooks) resolves inside the clone, and the reviewed commit's own post-checkout hook would have run there, outside every restriction — hooks are off while the tree is made; - a cancelled automatic review inside the hook let the loop start the next ref's review: the hook stops on it; an empty `codex --version` skipped the version guard: refused. The skill reviewed this change nine times. Each round found a real but smaller hole in the previous fix, which is the pattern the tool exists for, seen from the other side — so SKILL.md now says: at most two rounds per push, then push and let the bot judge. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(pre-review): check for the Codex CLI before probing it; scope the test's pkill to its own hook From CodeRabbit: the version probe ran before the existence check, so a missing CLI ended in "gave no version" and the install guidance was unreachable — the check comes first now; and the cancellation test's pkill matched any "hooks/pre-push origin" on the machine, a real push's hook in another clone included — it matches this run's hook path only. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(pre-review): escape the hook path before pkill -f (CodeRabbit) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(pre-review): no execpolicy rules or user config for the review; MCP roster read from the clone From thepastaclaw's third review: - the user's execpolicy allow rules (~/.codex/rules) could let a matching command run outside the sandbox, and the user's config.toml came along: codex exec runs with --ignore-rules and --ignore-user-config (the login still loads), and ~/.codex is an explicit deny in the profile — an allow rule for `cat` did not reach a canary file on 0.163 in a test, the flags are defence in depth; - MCP discovery and verification ran in the source checkout while exec runs in the review clone — different configuration contexts (a trusted checkout's own .codex/config.toml could mask a global server): both probes now run from the clone (-C); - the hook fetches the base once more before its final recheck, so a base that moved during a minutes-long review is seen. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * docs(pre-review): the rules of the loop — PR scope, 2–3 local rounds, blocking/major only, push back Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(pre-review): checkout under no user git config; probes and exec from inside the clone; keep config.toml From thepastaclaw's fourth review: - the review tree was checked out with the user's global/system git config in force, so a filter.<name>.smudge registered there ran for paths the reviewed commit's .gitattributes selects — the commit's code, outside every restriction: clone and checkout run with GIT_CONFIG_GLOBAL=/dev/null, GIT_CONFIG_NOSYSTEM=1 and no environment-supplied config (hooks stay off); a test registers such a filter and checks it stays quiet; - codex's -C does not move `mcp list`'s configuration context, so the probes still read the caller's checkout: the probes and exec now run with their working directory inside the review clone; - --ignore-user-config dropped a keyring-backed login (cli_auth_credentials_store): removed rather than carrying the store setting over. What config.toml could open is switched off and read back in the same context — MCP servers by name, apps/browser/computer use/web search — and --ignore-rules keeps the execpolicy allow rules out. Also the four rules of the loop in SKILL.md: only the PR's own code, two local rounds per push, locally blocking/major only, push back when a finding is out of scope or immaterial. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): MCP servers disabled in their own transport; lifecycle hooks off; the tool's scope written down From thepastaclaw's fifth review: - the disable entry `{ command = "/bin/sh", enabled = false }` merged with an HTTP server's `url`, and codex refused the configuration ("url is not supported for stdio") — the review could not start for anyone with an HTTP MCP server. The entry now follows the server's transport (`url` for http), checked on codex 0.163; the fake codex models the rejection; - codex lifecycle hooks from the user's trusted config ran outside the sandbox in the review clone: features.hooks=false, read back with the other capabilities. And the scope, in README and SKILL.md: the review is for our own branches before push — code the developer already builds and runs. It is not a sandbox for a hostile branch; the isolation it does apply is defence in depth. Findings of the class "a branch written to attack the reviewer escapes the review's isolation" are answered with this scope rather than with another isolation layer; a defect that breaks the review for an ordinary user is fixed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): TOML-escape paths in the codex configuration; python3 checked and documented From thepastaclaw's sixth review (no blocking findings left; two suggestions): - paths (CODEX_HOME, the review's temp folders, the prompt cache, alternate object stores) went into the permission profile and the env `set` as raw TOML strings, so a quote or backslash in one made the configuration invalid: each is encoded with JSON string escapes, valid in TOML basic strings; a test reviews with a TMPDIR holding both and parses the result back with tomllib; - python3 does the verdict lookup, the lock, the JSON work: the script checks for it first and says so, and README lists it with git. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): any MCP server name codex accepts; literal UTF-8 in TOML paths; tomllib optional in tests From thepastaclaw's seventh review, the narrowest fix for each: - the name filter ^[A-Za-z0-9_-]+$ refused valid names (docs.internal, npm:@scope/x), so the review never started for those users: the filter is gone, and the servers are switched off in one `mcp_servers={ "<name>" = {…}, … }` table with quoted keys — codex splits a dotted -c path on every dot, so the per-server form could not address them. Checked on codex 0.163; - json.dumps escaped non-BMP characters as UTF-16 surrogates, which TOML rejects: ensure_ascii=False; the path round-trip test now has an emoji in it; - that test needs tomllib (3.11+) while the script needs 3.8: it is skipped on an older python3, and README says so. Also rule 5 in SKILL.md: fix a bot's suggestion only when it is a line or two of the existing code — two of these three came from the previous round's suggestion fixes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(pre-review): unset the fake codex's controls before the cases run From thepastaclaw's eighth review (no blocking findings; one suggestion, a one-line fix): FAKE_* variables inherited from the caller could steer unrelated cases. Checked by running the suite with FAKE_LOGIN_RC=1, FAKE_FEAT_STUBBORN=1 and FAKE_LAST set in the caller's environment: all pass. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: andreika-baranouski <andrei.baranouski@gmail.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> * docs: code knowledge for the v12 line, from 722 review threads and a read of the code thepastaclaw and coderabbitai keep finding the same classes of defect on v12 PRs: an unreadable value treated as zero or absent, a fix that opens the next interleaving, an intent written after the act it protects. Each was rediscovered PR by PR, often over 20+ rounds. This writes them down once. docs/code-knowledge/ holds: - rules by area: fail-closed reads, concurrency, durability, money/SDK/Platform, lifecycle, security, testing, style, and working with the review bots. Each rule names the PRs it came from. - a pre-push checklist. - a project map of the v12 code: modules, flavors, cutover, sends, identities, shielded, persistence, tests/CI, gotchas. The sources are all bot threads on the 87 PRs into feat/kotlin-sdk-phase-1 (#1414-#1632), with the author replies and how each thread was resolved, plus an independent read of the tree at 421514a. CLAUDE.md links the new folder. It also corrects three stale facts: ViewBinding, not Data Binding; Gradle 8.13; and the Kotlin SDK owns L1 after the cutover. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(code-knowledge): correct the Compose palette, parseCoin rounding and CI test-coverage notes pre-review found three inaccuracies in the new docs: - MyTheme.Colors is the fixed light palette, so Compose code must read LocalDashColors.current; - Coin.parseCoin's fallback rounds to 8 significant digits, not to 8 decimals; - CI's testDebugUnitTest skips the flavoured wallet unit tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): a stale or missing verdict after a review exits non-zero prereview.sh returned 0 unless the fresh verdict read "blocking". If another invocation fetched a newer base while Codex ran, verdict() answered "stale" even for a review with blocking findings, and the standalone command reported success. The hook was not affected: it re-reads the verdict and refuses a stale one. Only clean and suggestions now count as a pass. A test moves the base during a blocking review and expects exit 1. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): fail when the verdict of a commit already on the base cannot be written When the commit had no commits over the base, the empty-range path wrote a clean record and returned 0 even if the write failed. The gate then found no record and refused, while the command had reported success. Return 2, as the other publication paths do. The docs now name the unqualified application CoroutineScope binding that exists, and note the L1-send exception to the pinned-on production flags. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): validate the counts line without a Python assert An assert is removed when the caller's environment has PYTHONOPTIMIZE set. A counts line such as {"blocking": null, ...} then passed validation and was published as a clean verdict, which the push gate trusts. The check is now an explicit raise. A test sets PYTHONOPTIMIZE=1 and expects exit 2 with no verdict. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review, docs): close the five review suggestions on #1637 pre-review tests: - The cancellation cases now wait for the fake to report it has reached its stall point, instead of sleeping a fixed two seconds. The fake then stays there until released, so on a slow machine the signal can neither come before Codex starts nor after a short fake finishes. - The chmod-based cases check that chmod really blocks a write, and are skipped where it does not. As root (in a container, say) chmod a-w blocks nothing, and those tests failed for a correct script. Checked on macOS and as root on Linux. Docs: - One local-round limit everywhere: at most two per push, a third only when the user asks for it. - The CI line in the project map no longer claims coverage of the flavoured wallet tests. - The marker recipe states what temp+fsync+ATOMIC_MOVE survives (process death), and what an OS crash also needs (fsync of the parent directory). - The future-start deadline rule is stated as an explicit check. - CLAUDE.md no longer says dashj does the blockchain work after the cutover. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): a failed codex mcp list stops the review; web search is set, not read back Both MCP probes ignored codex's exit status. A failed first probe left no servers to switch off. A failed read-back that still printed a list passed. Either failure now means no review, and a test covers it. web_search is a codex config value, not a feature, so `codex features list` has no row to read back. The -c on the command line outranks every config layer. README and the comments said it was read back; they now say it is set. The project map no longer calls root CLAUDE.md stale on Gradle, Data Binding and dashj, which this PR fixed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): a failed codex features list stops the review; docs: marker mechanisms and ATOMIC_MOVE The capability probe ignored codex's exit status, as the MCP probes did before 8b2c7fc. A failing probe that still printed every row as off passed the count check. Now no review runs, and a test covers it. The other probes already check theirs, or validate their output (--version). Docs: - 03 §3.11 says that AtomicMoveNotSupportedException is a failed write, not a cue for a plain move. Whether ATOMIC_MOVE replaces an existing target depends on the implementation, so pair it with REPLACE_EXISTING or never overwrite. - 08 lists what the three marker classes share, and the mechanism each one actually uses. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(code-knowledge): REPLACE_EXISTING does not change ATOMIC_MOVE's replacement behaviour Files.move ignores every other option under ATOMIC_MOVE (found by the local pre-review). A failed replacement aborts the write like any other step. On Android the move is rename(2), which replaces the target. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(pre-review): check each codex capability row once, not the count of false rows; #1607 has merged The read-back counted rows that named a capability and ended in false, so seven copies of one capability passed even if the others were missing or on. Each of the seven must now appear exactly once, and be false. Tests cover a listing made of copies of one row, a listing with one row duplicated, and a clean one. Checked with BSD awk and mawk. #1607 merged into feat/kotlin-sdk-phase-1 while this PR was open. It is gone from the docs' open-PR list, and only getAllOrThrow() (#1616) is still marked as not on the base. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * revert(pre-review): keep the skill identical to master's #1634 version This PR is code knowledge for v12. It carries the /pre-review skill only because v12 does not have #1634 yet. The hardening fixes made here in answer to review rounds (stale-verdict and empty-range exit status, assert under PYTHONOPTIMIZE, MCP and features probe exit status, the per-capability read-back, test synchronisation) changed a tool that was reviewed and merged in #1634. They belong in their own PR into master. They are kept on the local branch chore/prereview-hardening for that. .claude/skills/pre-review/ now matches origin/master (cdaf542) byte for byte. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(code-knowledge): #1630 has merged; REPLACE_EXISTING is not part of the atomic-marker guarantee #1630 merged into feat/kotlin-sdk-phase-1 while this PR was open, so it comes off the open-PR list. BackupReplacementState passes REPLACE_EXISTING, but ATOMIC_MOVE ignores it, so 08 no longer lists it as part of the mechanism. 08 also states that arm() and complete() both run under the AtomicFileWriter lock. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(code-knowledge): correct GlobalScope and Java counts; marker check and publish share one lock GlobalScope is launched in 2 files; BaseConfig only imports it. wallet/src holds 110 Java files, and 115 is the module including its tests. §3.11 now says that a marker's state check and its publishing write belong under one writer lock. BackupReplacementState does that, and WalletWipeState.begin() relies on not running concurrently. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(code-knowledge): generation markers may be replaced; the protocol latch is an AtomicFile, not SharedPreferences From the local pre-review: - §3.11's "never overwrite a pending marker" holds for markers whose content is the authority (WalletWipeState). BackupReplacementState.arm() replaces a pending marker with a new generation by design. - §3.14 named ProtocolVersionLatch as a commit() latch. It keeps its mark in its own AtomicFile, with the data and directory fsynced and the file read back, because SharedPreferences cannot tell unreadable from absent.

…d reserves #1616's aDeferredBuildWithNoCommittedCursorRecordsNoHeight built a deferred Maya deposit with walletSyncedHeight = 0 and expected a null reservation height. With this branch's funding gate an unknown cursor is refused first ("SDK L1 wallet scan cursor is not known yet"), so that build is no longer reachable. The test now asserts the refusal and that nothing was reserved; reservationHeightLowerBound()'s null stays as the defence behind the gate. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Re-review — Final validation — Phase 1 + Phase 2
Static verification of the exact head found no in-scope defects. The funding gate, default-network tracking, replay wake-lock coordination, watchdog lifecycle, and bind-heal generation checks address the twelve fixable prior findings; the two remaining fund-safety gaps are pre-existing and tracked separately. The build and check CI jobs were still queued, with no completed code-check failure to weigh.

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Durable launch-seed persist keeps the aggregate/unknown-cursor gap — The durable balance-seed persistence path still does not apply the funding gate's aggregate-sync and unknown-cursor protections. This behavior predates the reviewed changes, is not worsened by this PR, and is tracked separately.
- Follow-up: Address the durable balance-seed gate and add regression coverage in #1641.
- Deferred broadcast never re-checks the funding gate — Deferred BIP70 and Maya payments can still broadcast a previously built transaction without re-evaluating the current synchronization gate immediately before broadcast. This adjacent behavior predates the reviewed changes, is not worsened by this PR, and is tracked separately.
- Follow-up: Add a final funding-gate check before deferred BIP70 and Maya broadcasts in #1642.

feat/kotlin-sdk-phase-1that came up in #1584. After the base was merged into #1584, six CodeRabbit threads pointed at code identical to the base, and two test classes failed on a clean base checkout. One commit per fix:scanCaughtUpToTip, which also accepts the iOS aggregate rule (up to ~0.3% of chain height short, ~4,600 blocks on testnet). With the wallet cursor unknown (0), the pipeline-lag veto had nothing to act on, so a spend could open with thousands of blocks unscanned. The gate now also requires the filter scan withinSCAN_TIP_TOLERANCE_BLOCKSof the highest tip the snapshot knows. That also covers a stale header target that dash-spv restores at engine start. The gate's pipeline-lag veto measures against the same tip. The gate also closes while the engine waits for peers (CONNECTING), whose snapshot can keep the previous session's heights, and while the wallet cursor is unknown (0). dash-spv emitsSyncHeightAdvancedfor every wallet each committed batch covers, and the cursor is seeded from the SDK's durable synced height at start, so an unknown cursor doesn't block a synced wallet. That was checked on the emulator with a fresh testnet wallet. Nothing that used to stay closed now opens. The display predicate is unchanged.PARTIAL_WAKE_LOCKwhile offline, and after the filter-stall watchdog had given up on a wedge. Now the lock is released in both cases but the service stays up. Stopping it would re-walk from the durable watermark and loop through the replay restart alarm, which is why theSdkBlockchainStateMappersuggestion to end the replay on EXHAUSTED is not taken.TIME_TICKis not delivered while the CPU sleeps, so the lock is re-acquired the moment the replay is due again: when the impediment clears, and when the filter wedge clears. The service watches a count of wedge clears, which the engine's progress feed and wallet events update as they happen. A count can't lose a clear the way a mirrored true/false flag can when its observer runs late. The hold lives inReplayWakeLock. The tick and every event (impediment change, wedge clear) make the same check under one lock, and each can acquire or release. A check that read "due" just before a network loss is then undone by the loss's own check. The NETWORK impediment now follows the default network (registerDefaultNetworkCallback,DefaultNetworkTracker): before, it was set by any validated network, so a validated secondary network could say "online" while the default route was down. This also changes the dashj path's NETWORK impediment, which reads the same flag. The service also reads current connectivity when it starts, after registering the network callback: the callback reports nothing while there is no default network, so a service started offline used to treat itself as online. That read never overrides a callback update. Network callbacks now run one at a time, in the order they arrive.onDestroyretires the lock so a late callback cannot re-acquire it after teardown.bindHealL1Starter.arm()left a waiter that survived the teardown. A later bind heal then started L1 with no foreground service.armand the kick'scancelnow check the lifetime under the starter's lock, so a stale start request can neither arm a waiter that outlives its service nor replace or cancel the current one. The waiter re-reads the lifetime after the heal and passes the engine's stop generation, sampled before those checks, tostartIfEnabled. A shutdown that finishes the engine stop between the checks and the start therefore keeps L1 down.arm/cancelare serialized and the job fields are@Volatile.PlatformSyncEngineRestartTest.resume_isRearmableAcrossRepeatedStopRestartCycleswent stale within fix(upgrade): v12 cutover and sync lifecycle, plus a measured account of what still loses money #1568: a later commit there made a stop cancel a kick still waiting on its bind. The production behaviour is right, so the test now waits for each cycle's start, and a new test pins the cancellation.CutoverUiDataServiceTestcases failed because of aDispatchers.IOhop inside every refresh (added in fix(receive): serve the receive address from the SDK engine, not the held dashj chain #1570).runCurrent()could return before the refresh published.
