Chip review — no blocking findings — this is not an approval
No findings. The DB-first controller-repair revision is coherent end to end: the client contract (POST /rain/cards/controller/refresh with empty body, {coordinatorAddress, changed} response, 10/min rate limit; 400 STALE_CARD_APPROVAL on session-approve) matches the paired peanut-api-ts #1624 head exactly, including the OpenAPI snapshot. Repair fires only on failed Rain legs, never on success or local passkey-ceremony cancellations, preserves the original error/result, and never re-signs or re-submits; the crossed-attempt failure is retained so a later fallback cancellation cannot hide it. The pre-grant fresh overview fetch is fail-closed, and the removed post-grant invalidation is redundant because the awaited shared-query refetch already updates every observer. All substantive CI checks are green at this head (ds-shots still in progress at review time; the base carries 4 pre-existing failing check runs).
Checked clean
- Client/backend contract for the new refresh endpoint and the session-approve 400 STALE_CARD_APPROVAL branch, verified line-by-line against the paired peanut-api-ts PR #1624 (head 93c465f4) route schemas and the generated OpenAPI snapshot
- Repair trigger matrix across all three spend engines (useSpendBundle, useSignSpendBundle, submitSignedSpend callers in manteca withdraw and qr-pay): no refresh on success or pending, ceremony-cancellation skip via WebAuthn error names and SessionKeyGrantRequiredError user-cancelled cause, crossedRainFailure retention for post-broadcast fallback cancellations, original error/result preserved and nothing re-submitted (backend refresh route confirmed inert: stores an address only)
- runSerialize fresh-overview refetch: fail-closed on refetch failure, no-contracts path preserved, re-issue (serializeGrant) gate unaffected; removed post-grant invalidateQueries is redundant on the success path because the awaited shared-query refetch propagates to all observers
- StaleCardApprovalError wiring: 409 submit branch still dispatches the re-enable event, new 400 session-approve branch types the error without dispatching (no modal re-entry loop), friendlyError mapping intact
- Security surface: refresh call is authenticated, rate-limited, and cache-only; no secrets, injection, privilege changes, or caller-influenced amounts; grants now pin to a fresh server-side coordinator instead of a cached copy (strictly tighter)

Chip review — no blocking findings — this is not an approval
Rain controller-rotation recovery for spend bundles, QR payments and bank withdrawals: re-sign under the same lock after a proven no-effect failure, one bounded recovery attempt, grants re-pinned to the live coordinator. Deep correctness/adversarial pass over the recovery chains, replay accounting, cooldown handling and unmount guards found them sound; one minor wire-contract edge on the QR init idempotency key.
Findings
- MINOR · src/utils/qr-payment.utils.ts:69 · QR init idempotency keys change for every existing caller across this deploy
The newreplacementslot appends an empty 4th element to the canonical string for every caller that does not set it:[ts, qr, amount, ''].join('\u0000')yieldsts\0qr\0amount\0where the old composition ended atts\0qr\0amount(verified by direct evaluation). The second hash half also keys oncanonical.length, so every same-scan key produced by this client differs from the keys minted by the currently deployed client. That breaks the function's own contract ("MUST be identical across every retry of one scan") at the deploy boundary: a scan whose init already created a lock on the old client, then re-initialized by the new client (web redeploy mid-session, native OTA update), reaches/manteca/qr-payment/initwith a different key, so the backend mints a second price lock instead of replaying the first — exactly the duplicate-lock behavior the key exists to prevent. Retries within one client version are unaffected (the key is memoized in memory). Outcome is benign (the orphaned lock expires unused, the user confirms the fresh quote), hence minor. Fix: append the replacement only when present, restoring the pre-PR canonical for all existing callers; recovery keys are introduced by this PR and have no deployed form to stay compatible with. Existing call sites: scan key at useQrPayFlow.ts:98, open-amount re-init at useQrPayFlow.ts:603.
Checked clean
- Controller-rotation recovery in useSignSpendBundle: single re-sign under the same resolved terms and lock, superseded prep cancelled, replacement attempts left to the backend TTL sweep when they fail, cooldown wait fits the lock or surfaces the typed quote-review outcome
- useSpendBundle broadcast-engine recovery: revert-proof accounting (allSettled across every broadcast attempt; an ambiguous ephemeral broadcast is never rehabilitated by a later confirmed revert), recovery bounded to one attempt per spend
- Grant-after-prepare (ensurePreparedControllerApproval): refetch-then-grant pins the live coordinator, a second rotation surfaces the typed stale-approval path, grant loop terminates; mixed legs correctly never grant
- submitSignedSpend / useSignedSpendRecovery: submits only the replacement artifact, at most one recovery per submission, user dismissal surfaces the typed ABORT; unmount guards verified by tests (controller refresh or re-sign resolving after the user leaves submits nothing)
- Forced collateral-only direct routes (useReturnExcessCollateral, LockCardModal, CancelCardModal) unchanged: strategy assertion intact, no cancel on execution-ambiguous submit failures
- StaleCardApprovalError and RainCooldownError carry their wire codes, so wireErrorCode and the typed grant/recovery chains resolve; the session-approve path no longer re-dispatches the re-enable event, avoiding the modal reopening on itself
- Generated API types match the new /rain/cards/controller/refresh endpoint and the preparedCoordinatorAddress field on prepare responses
- QR and bank-page quote recovery: replacement idempotency key stable per recovery event (reset on success, reused across retries after a failed re-quote), re-entry guarded, failed re-quote leaves a retryable path; the bank page cancels recovery on unmount
- CI at head: unit, typecheck, eslint, format, CodeQL, bot-approval, human-authors all green; ds-shots still in progress (visual snapshots, non-blocking)

Chip review — no blocking findings — this is not an approval
Reviewed the Rain controller-rotation recovery across both spend engines, the sign-only engine, and both provider flows (QR pay, bank offramp). The money-critical invariants hold: recovery acts only on structured wire codes (never message text), success/pending/unknown outcomes never authorize a replacement, an ambiguous broadcast permanently disqualifies the mixed leg, confirmed reverts require a receipt that strictly reported success === false, every engine retries at most once, and quote expiry is checked before signing, after signing, and inside the submit callback for replacement attempts too. Against the current backend the whole recovery is provably inert (RAIN_CONTROLLER_CHANGED, USER_OP_REJECTED and POST /rain/cards/controller/refresh do not exist in the sibling policy branch, and every refresh call site swallows errors), so deploy order is safe; the pre-effect discipline of the new codes is a contract owned by the unmerged peanut-api-ts#1624 and could not be verified from this side. Prior finding P1 is verified fixed. Two minor cleanup gaps found, neither holding the merge.
Findings
-
MINOR · src/hooks/wallet/useSignSpendBundle.ts:540 · Replacement sign attempt never backs out its own preparation draft
When controller-rotation recovery re-runs runSignAttempt(), its /prepare succeeds and sets livePreparationId — but if a later step of the replacement fails (user dismisses the passkey, the inline grant fails, or any unexpected error), every exit inside theif (rotated)block (thethrow againandthrow finalpaths and the typed aborts) propagates without the best-effort cancelPreparation cleanup that the non-recovery path gives every first-attempt failure. The fresh prep then lingers until the backend TTL sweep, and the controller-cache repair and CARD_WITHDRAW_FAILED telemetry are skipped for a genuinely failed replacement. useSpendBundle does not have this gap: its recovery failures fall into the outer catch that cancels the draft when nothing was broadcast — and this engine never broadcasts anything, so a cancel here is always safe. Fix: run the same livePreparationId cleanup (plus the repair/telemetry) on each replacement-failure exit before rethrowing. -
MINOR · src/features/payments/flows/qr-pay/useQrPayFlow.ts:509 · QR quote-recovery wait is not cancelled when the screen unmounts
handleQuoteRecovery's cooldown wait only observes quoteRecoveryCancelledRef, which nothing sets on unmount — only the in-app back button (onBackFromQrPay → cancelQuoteRecovery) cancels it. If the user leaves the QR screen any other way (browser or gesture back, tab close), the wait runs to completion and initiateQrPayment still mints a replacement Manteca price lock nobody will see, with setPaymentLock firing on an unmounted component. The sibling withdraw page gates the identical wait on unmount (manteca/page.tsx sets quoteRecoveryCancelledRef.current = true in a useEffect cleanup) and the sign/spend recovery hooks gate on their own unmount refs, so this contradicts the PR's own "leaving the screen stops unsent recovery work" invariant. No funds move and the wasted lock expires, but the hook should mirror the withdraw page's unmount effect. -
MAJOR · src/hooks/wallet/useSignedSpendRecovery.ts:122 · [claude-opus] The "cooldown fits the lock" recovery branch — wait, re-sign, re-submit — has no test anywhere
Both recovery engines have two exits when Rain returns a 425 during the replacement prepare: hand back a SpendRecoveryQuoteReviewError, or wait the cooldown out and re-submit inside the same provider lock. Only the first is tested.
The untested case, exactly: a controller-rotation recovery whose re-prepare hits RainCooldownError with a retryAfterSec such that Date.now() + retryAfterSec*1000 + 20_000 <= lockExpiresAt — i.e. fitsLock === true at src/hooks/wallet/useSignedSpendRecovery.ts:122 and src/hooks/wallet/useSignSpendBundle.ts:543. The code then sleepUnlessCancelled(retryAfterSec*1000), re-prepares, re-signs, and in the post-submit engine sends a second completeQrPaymentWithSignedTx / withdrawWithSignedTx against the same paymentLockCode / priceLockCode. That is a second money-moving request issued autonomously after an unattended timed wait — no user tap in between.
Evidence that nothing covers it: grep -rn lockExpiresAt src --include=*.test.ts* returns only submitSignedSpendRepair.test.tsx:140 (the helper's option type) and :299, where the value is deliberately chosen so the cooldown cannot fit ("a cooldown that cannot fit the lock surfaces the typed QUOTE REVIEW outcome", 600s cooldown vs a 60s lock). useSignSpendBundle's signMixedSpend() / signOrdinary() helpers never pass lockExpiresAt at all, so its 425 test at useSignSpendBundle.test.tsx:452 also takes the !fitsLock exit. The page-level fake-timer tests (qr-pay-states "a known Rain cooldown finishes BEFORE the replacement quote is minted", manteca-withdraw-gates "a quote-review handoff waits, re-locks the same amount") exercise the call sites' own wait before re-quoting, which is the opposite branch.
Fix: add two cases mirroring the existing ones but with a lock that outlives the cooldown — (1) in submitSignedSpendRepair.test.tsx, resign throws new RainCooldownError('cooling down', 2) with { lockExpiresAt: Date.now() + 120_000 }, then assert under fake timers that the wait elapses, the second submit receives the replacement artifact and the same lock code, and that exactly two submissions happened; (2) the same shape in useSignSpendBundle.test.tsx via a lockExpiresAt on the signSpend input, asserting a third prepareWithdrawal is not made and the returned artifact carries the fresh prep. Also worth one negative: leaving the screen mid-wait yields SpendRecoveryAbortedError and submits nothing (the sleepUnlessCancelled false path, likewise unexercised).
Checked clean
- Prior finding P1 (QR init idempotency key drift) verified fixed: with
replacementabsent the canonical string is byte-identical to the deployed three-field format; both pinned vectors recomputed from the merge-base source match the tests at this head; existing call sites pass no replacement field - Deploy-order safety against the current backend: RAIN_CONTROLLER_CHANGED, USER_OP_REJECTED and POST /rain/cards/controller/refresh are absent from the sibling policy branch (peanut-api-ts at 7a804a2a), every refreshControllerAddress call site swallows its error, and the extra preparedCoordinatorAddress submit field is optional and ignored by the existing Ajv schemas — recovery is inert until the paired backend ships
- Replay-once bounds and no-effect proofs in submitSignedSpend, useSignedSpendRecovery and both spend engines: structured wire codes only, success/pending never recover, ambiguous broadcasts permanently disqualify the mixed leg, confirmed reverts require receipt success === false strictly
- User-departure gates: abortReplacementIfGone/abortIfGone chains in both engines and SpendRecoveryAbortedError handling in both flows, with 'resolves AFTER the user leaves' regression tests
- Quote expiry checked before signing, after signing and inside the submit callback for every attempt including replacements; replacement quote identity stable per recovery event and distinct from the scan key; open-amount re-init keys unchanged
- Session-key grant moved after /prepare and pins the coordinator from a fresh overview refetch; stale-approval (400 STALE_CARD_APPROVAL) typed through to the re-enable modal without re-dispatching the window event; mixed never re-grants
- chargeId-backed preps never cancelled by recovery or failure paths; cooldown waits bounded at 600s and skipped for provider-quoted kinds; ephemeral revertConfirmed flag strictly false-only
- i18n keys (cardUpdatedReviewQuote, rotatedError) present in en, es-419, es-AR and pt-BR
- CI green at this head (unit, typecheck, eslint, format, analyze, human-authors, bot-approval); ds-shots and Deploy-Preview still in progress

Chip review — no blocking findings — this is not an approval
Round-4 re-review of the Rain controller-rotation recovery (TASK-22734). All four prior findings verified fixed at this head: QR init keys stay byte-identical for existing callers, the replacement sign attempt backs its own draft out through one failure exit, the QR quote-recovery wait cancels on unmount, and the cooldown-fits-the-lock branch is now tested in both recovery engines. Replay-safety invariants hold end to end: only structured no-effect codes (RAIN_CONTROLLER_CHANGED, or USER_OP_REVERTED/REJECTED on a broadcast-first mixed artifact with a genuinely moved controller) authorize a replacement; ambiguous broadcasts, message-only reverts and pending outcomes never do; and every unsent replacement step is gated on the user still being on the screen. One minor duplication finding remains.
Findings
-
MINOR · src/hooks/wallet/useSignSpendBundle.ts:547 · Cooldown-fits-the-lock recovery logic is implemented twice
src/hooks/wallet/useSignSpendBundle.ts:547-560 and src/hooks/wallet/useSignedSpendRecovery.ts:121-130 hand-copy the same money-path timing policy: each defines its own RESIGN_MARGIN_MS = 20_000 (lines 137 / 25), the same fitsLock arithmetic against lockExpiresAt, the same cancellable sleepUnlessCancelled wait, the same abort when the user leaves, and the same second-cooldown -> SpendRecoveryQuoteReviewError outcome. These are the two engines every quoted payment runs on (QR pay vs bank offramp), so a future change to the margin or the fits rule applied to only one copy makes the two payment surfaces silently use different recovery windows - one waits out a cooldown the other hands to quote review. Practical fix: extract one shared helper (e.g. in signSpendRetry.ts, taking retryAfterSec, lockExpiresAt, an isGone callback and a retry thunk) and drive both engines from it; the existing engine-specific tests already pin the behaviour on both sides. -
MINOR · src/features/payments/flows/qr-pay/useQrPayFlow.ts:515 · [claude-opus] Quote-expiry re-quote tells non-cardholders their card was updated
handleQuoteRecovery(useQrPayFlow.ts:505) unconditionally setssetQuoteUpdatedNotice(t('cardUpdatedReviewQuote'))at line 515 — "Your card was updated. Review the current quote to continue." But it is entered from three places, only one of which is a controller rotation: -
useQrPayFlow.ts:698 —
quoteExpired()before signing -
useQrPayFlow.ts:753 — quote died while signing
-
useQrPayFlow.ts:599 — retry after a failed re-quote
None of those involve the card. The check runs before signSpend, so it fires for a smart-only QR payment by a user who has never been issued a Peanut Card (QR pay via Mercado Pago/Pix is a standalone spending method — product/spending.md "Mercado Pago Integration" / "Pix Integration"). The same shape exists on the offramp: page.tsx:519 sets the notice, reached from page.tsx:640 and :700 on a plain price-lock expiry. The new test at qr-pay-states.test.tsx:1780 asserts quote-updated-notice is rendered for an already-expired quote, so the behaviour is intentional as written.
Product truth disagrees with the code, and the code is the wrong side: product/spending.md:261 documents this case as "Rate changed during review: User is re-quoted with the updated rate" — a rate event, with no card claim. Telling a cardless user their card was updated is simply false, and for a cardholder it wrongly implies a card-side change when only the merchant/FX quote moved.
Fix: keep cardUpdatedReviewQuote for the rotation-driven handoff only (the SpendRecoveryQuoteReviewError that came out of signSpend/submitSignedSpend), and add a neutral string for the expiry/retry entries — e.g. quoteExpiredReviewQuote: "This quote expired. Review the current quote to continue." Threading a reason: 'rotation' | 'expired' through handleQuoteRecovery / runQuoteRecovery is enough; both call sites already construct the error locally, so the discriminator is free.
Checked clean
- Prior findings P1-P4 re-verified at head: QR idempotency key canonical string byte-identical without the replacement field (deployed-key regression vectors present), replacement draft back-out via one failure exit, QR quote-recovery wait cancelled on unmount with checks before init and before setPaymentLock, and fitsLock wait/re-sign/re-submit covered in both engines
- Replay-safety invariants of all three recovery engines: only structured no-effect codes plus a genuinely moved controller authorize a re-prepare; ambiguous broadcasts, message-only reverts, pending/successful outcomes, legacy mixed capabilities and unknown transport failures never do; exactly one retry per flow
- Unmount/departure guards at every boundary of unsent replacement work (useSpendBundle, useSignSpendBundle, useSignedSpendRecovery, both quote-recovery flows); already-sent work keeps its reconciliation
- Cooldown handling: fitsLock arithmetic vs lockExpiresAt incl. the 20s resign margin, mid-wait cancellation, second-cooldown outcomes, provider-quoted kinds never parked in a wait
- Grant gate reordering (ensurePreparedControllerApproval after /prepare): grant targets the freshest overview coordinator, stale-approval is a typed rotation candidate confirmed against a real controller move, mixed never grants
- submitSignedSpend contract: resolved vs thrown failures, onFailure observes only the final failure, typed recovery outcomes excluded from repair, unexpected recovery errors swallowed so the first attempt's money-truth stands
- QR and offramp call sites: quote expiry checked before signing and before every submission including the replacement; re-quote retry cannot submit the dead lock; replacement QR keys stable per recovery event
- i18n key parity (en, es-419, es-AR, pt-BR) for cardUpdatedReviewQuote and staleCardApprovalModal.rotatedError; regenerated openapi/generated types consistent with the new endpoints and typed codes
- CI at this head: unit, typecheck, eslint, format, CodeQL, bot-approval, human-authors all green
- Backend sibling (policy branch) lacks RAIN_CONTROLLER_CHANGED / controller refresh - expected, the paired change is peanut-api-ts#1624, and the frontend fails closed without it

MINOR: Cooldown-fits-the-lock recovery logic is implemented twice
src/hooks/wallet/useSignSpendBundle.ts:547-560 and src/hooks/wallet/useSignedSpendRecovery.ts:121-130 hand-copy the same money-path timing policy: each defines its own RESIGN_MARGIN_MS = 20_000 (lines 137 / 25), the same fitsLock arithmetic against lockExpiresAt, the same cancellable sleepUnlessCancelled wait, the same abort when the user leaves, and the same second-cooldown -> SpendRecoveryQuoteReviewError outcome. These are the two engines every quoted payment runs on (QR pay vs bank offramp), so a future change to the margin or the fits rule applied to only one copy makes the two payment surfaces silently use different recovery windows - one waits out a cooldown the other hands to quote review. Practical fix: extract one shared helper (e.g. in signSpendRetry.ts, taking retryAfterSec, lockExpiresAt, an isGone callback and a retry thunk) and drive both engines from it; the existing engine-specific tests already pin the behaviour on both sides.

Keep a payment open when Rain changes its controller. Use the cached controller normally; after a proven recoverable failure, refresh it, obtain current authorization and retry once inside the same flow. Do not show a payment failure for the recovered internal attempt or a cancelled recovery prompt.
QR and bank withdrawals keep their original quote when recovery fits its lifetime. Otherwise, wait for Rain's cooldown, obtain a fresh quote and return to review with a neutral notice. The user must confirm the new terms before funds move. Failed quote refreshes retry only the quote, retaining the QR request identity. Ordinary QR init keys preserve the deployed format; only replacement quotes add a stable recovery key. Expiry is checked before signing and before every submission, including a signed replacement. Unknown or pending submissions never start a replacement payment.
Full-collateral QR and bank withdrawals use the existing atomic mixed funding path with zero smart-account contribution. This prevents a controller rotation from leaving a provider order without funding. Card lock/cancel keep their explicit collateral path. Direct crypto withdrawals retain their routing and use the API's precise recovery signal. A typed stale approval during grant saving also recovers after a trusted controller-address change, before any financial submission. Standalone abandoned preparations retain their existing best-effort cleanup; charge-backed payments are never cancelled by that cleanup.
Task: TASK-22734. Backend: peanut-api-ts#1624.
Design and rollout
Deploy the backend first. The normal success path adds no Rain contracts request. Recovery may need another passkey approval. Full-collateral quoted payments may need two passkey prompts on fallback; the existing ephemeral path can retain one. Existing mixed rounding can leave less than one cent in the smart account.
Automatic replacement requires a pre-effect controller refusal or a definitive failed broadcast under the backend's modern mixed contract, plus a changed controller. Message text, generic exceptions, successful or pending responses, legacy artifacts and prior ambiguous sends cannot authorize a new payment. A quote refresh is never permission to spend under changed terms. Leaving the screen stops unsent recovery work; submitted work retains reconciliation.
Validation
Local gate at c9aec00: 580 suites and 7,207 tests passed (5 skipped). Typecheck, repository formatting, changed-file lint and the production build passed. API type generation passed before the final source-only fixes; no generated contract changed. Three existing hook-dependency warnings remain outside the final six-file fix.
Regressions cover controller rotation, initial and replacement quote expiry, cooldowns that fit the existing quote, cancellation during the wait, quote-only retry then separate confirmation, and stable QR keys. Real QR and bank-flow tests pin the unchanged lock, amount and recipient while checking fresh preparation IDs. Replacement failures clean their standalone preparation and report one final error; typed cancellation and quote-review handoffs do not report failed payments. QR unmount cancels the pending quote request. The previous review's two cleanup findings and timed-recovery coverage gap are fixed. All current-head CI checks passed, including preview, native export and visual fixtures. Review at this head verified the recovery safeguards and prior fixes. Two minor corrections are complete locally: a shared cooldown rule and neutral quote-review text in all four locales. The full gate passed again, but the final commit awaits the desktop GPG unlock. Push, CI and review of that commit remain outstanding; this PR stays draft.
Screenshots: NONE. No existing fixture exposes these two recovery states, and no sandbox provider payment was run. The existing inline info Notification composition was checked; automated tests verify the state transitions. This is not visual or end-to-end payment evidence. Native: no positioning, input, safe-area or viewport behavior change. Provider rotation has not been exercised with real funds.
Separate content follow-up: qualify card-collateral cooldown and one-tap claims. No legal policy change is needed; renewed exchange terms still require confirmation.
