Findings from the review of merged PR #1411 and the Server App rate-limit test failure described in the handoff.
Summary
Fixes multi-counter checkout retries and existing-order append routing, keeps dine-in tables occupied until explicit completion, adds whole-ticket payment queue totals and store-timezone timestamps, repairs payment-ticket text layout and merchant naming, and translates the counter settings controls in all 24 locales. The multi-counter browser fixture now tracks and cleans every created order, and Server App rate-limit probes run sequentially.
Scope
Persist postpaid order idempotency keys before submission and reuse them after lock/remount.
Guard order completion UI and cart clearing against session changes and newer attempts.
Keep append-to-existing-order actions ahead of counter mode for buttons and shortcuts.
Preserve dine-in table occupancy after kitchen service until explicit completion.
Aggregate outstanding split-check balances and collected amounts while preserving selected-bill fields.
Render payment queue times in the configured store timezone.
Wrap long payment-ticket item names while retaining full amounts on 58mm and 80mm layouts, and treat catalog names as text.
Use supported paired printer formatting tokens.
Print the configured business_name with the existing fallback.
Translate counter settings controls, states, hints, and errors across all 24 locales.
Restore test-created orders and prior settings, and assert cleanup responses.
Run the Server App customer and printer rate-limit probes sequentially without changing production limits.

The following are alternative approaches to this PR:
1. Share a submission coordinator across checkout modes
➕ Centralizes session guards and retry-state cleanup for prepaid and postpaid orders.
➖ Broadens a corrective PR into a riskier refactor of existing checkout paths.
Recommendation: Keep the scoped fix, which reuses existing attempt-storage primitives without changing unrelated checkout behavior. Consider a shared coordinator separately if submission lifecycles continue to diverge.

1. Switching checkout modes can duplicate orders✓ Resolved
Description
handleSendToPayment stores a postpaid attempt under a cart fingerprint, but normal
handlePlaceOrder matches attempts against a differently structured serialized order payload and
therefore chooses a fresh idempotency key. If a send-to-payment request commits but its response is
lost, switching to normal checkout with the same cart can create a second order instead of
recovering the first.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The changed path persists buildCurrentCartFingerprint for send-to-payment, while normal checkout
compares against JSON.stringify(orderPayload); its body also omits the send request's
dispatch_policy: 'on_payment'. The server's idempotency protection applies per key, so creating a
new key permits another order.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
A send-to-payment attempt and a normal checkout attempt for the same cart use different request bodies but share postpaid retry storage. After an uncertain send, normal checkout can issue a fresh key and duplicate the order.
## Fix Focus Areas
- frontend/src/app/(dashboard)/pos/page.tsx[2005-2039]
- frontend/src/app/(dashboard)/pos/page.tsx[1720-1805]
## Recommended Fix
Persist enough request-body and checkout-mode information to identify an unresolved attempt. Before either mode submits a different payload, require recovery or explicit resolution of the original request; reuse an idempotency key only with its exact original payload. Add a test for switching modes after a committed request whose response was lost.

2. Next cashier can resend a ticket that already exists✓ Resolved
Description
In handleSendToPayment, the if (!isOriginSessionCurrent()) return; right after
api.post('/orders', …) exits without clearing the shared cart. The postpaid handlePlaceOrder
path clears the cart in this same situation when its fingerprint still matches. If the PIN user
switches or the screen locks while the request is in flight, the next user sees the full cart and
can press Send to payment again. Their attempt is stored under their own user id with a new
idempotency key, so the server creates a second awaiting-payment ticket for the same order.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The postpaid place-order path documents a 'Critical recovery invariant': when the order succeeded
but the session changed, it clears the cart if the fingerprint matches, so the new session cannot
submit it twice. The new send-to-payment path returns early without doing this. Idempotency attempts
are stored per user (getPostpaidOrderAttemptStorageKey(originUserId)), so a different user
generates a fresh key and the server does not deduplicate.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
In `handleSendToPayment`, a successful POST followed by a session change returns early and leaves the cart in place. The next session can then send the same order again under a new idempotency key.
## Fix Focus Areas
- frontend/src/app/(dashboard)/pos/page.tsx[2042-2042]
## Recommended Fix
Replace `if (!isOriginSessionCurrent()) return;` with a block that does what the postpaid path does: if `buildCartFingerprintFromState(useCartStore.getState()) === cartFingerprint`, call `useCartStore.getState().clearCart()`, then return. Keep the origin user's stored attempt so that user can still recover the order.

3. A cleanup failure leaves test settings changed✓ Resolved
Description
The multi-counter browser test's finally block now makes throwing assertions inside the
order-cleanup loop before it restores either setting. If any cleanup request fails, teardown stops
there, leaving the test's counter configuration or store timezone in place and potentially obscuring
the original test failure.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The test sets a new timezone and multi-counter configuration, but restoration occurs after an order
loop containing immediate-throw assertions for reads, payments, release, and completion. A failed
assertion exits the finally block before those later calls.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
A throwing assertion in order teardown prevents later fixture cleanup and restoration of settings that the test changed.
## Fix Focus Areas
- frontend/e2e/multi-counter-ordering.spec.ts[852-946]
- frontend/e2e/multi-counter-ordering.spec.ts[948-990]
## Recommended Fix
Attempt independent cleanup and settings restoration even when an earlier step fails. Collect cleanup errors and report them after all restoration attempts, without replacing the original test failure.

4. A matching later cart can reuse an old ticket's key✓ Resolved
Description
When clearOrderAttempt fails after a successful send (cleanupFailed), the stored
PostpaidAttempt keeps its idempotency key and is never marked with the created order. The next
Send to payment with the same cart fingerprint, for example the next customer ordering the same
items, reuses storedAttempt.idempotencyKey. The server replays the earlier response, so no new
order is created and the cashier is shown the previous customer's ticket. handlePlaceOrder blocks
this case through its priorOrderAttempt.order check, but this path has no equivalent guard.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The send path reuses any stored attempt with a matching fingerprint and does not check whether that
attempt already produced an order. The postpaid path saves confirmedAttempt with order and
refuses to reuse an attempt that already has an order.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
After a successful send, a failed attempt cleanup leaves a reusable idempotency key. A later identical cart then replays the old order instead of creating a new ticket.
## Fix Focus Areas
- frontend/src/app/(dashboard)/pos/page.tsx[2008-2019]
- frontend/src/app/(dashboard)/pos/page.tsx[2042-2070]
## Recommended Fix
Right after the POST succeeds, save `{ ...attempt, order: data.order }` with `savePostpaidAttempt`. When reading `storedAttempt`, treat an attempt that already has an `order` as consumed: report the cleanup-failed state, as `handlePlaceOrder` does, or generate a fresh key. Do not reuse its idempotency key.

5. Catalog names can cut payment tickets✓ Resolved
Description
printPaymentTicket places wrapped, unescaped product-name fragments on indented continuation
lines, while the printer formatter recognizes a line containing {CUT} or {INIT} even after
trimming its indentation. A catalog name containing a wrapped standalone token can therefore cut or
reset the printer before the balance and ticket QR are printed.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
Product names enter order items without printer-token escaping. The new continuation lines make a
token independently parseable, and the formatter's trimmed-line checks emit printer control bytes
before the ticket is dispatched.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
Wrapped product names can produce standalone printer-control tokens on continuation lines, which the formatter executes rather than printing as catalog text.
## Fix Focus Areas
- main/printers/thermal.ts[1480-1492]
- main/printers/thermal.ts[1452-1456]
## Recommended Fix
Apply the existing `safePrinterText` escaping to untrusted ticket text before wrapping or interpolating it, including product and business names. Test a long product name with a continuation-line `{CUT}` token and verify that the ticket still prints its balance and QR.

- Line 316: Update the GET /awaiting-payment API reference row to describe the
route’s actual ordering, including created_at ASC, and remove claims that orders
are hydrated with items, bills, customer, and table; document only the flat
fields the route returns.
Review comments at @frontend/src/app/(dashboard)/pos/page.tsx:
- Around line 2044-2070: Update the post-success recovery flow around
readOrderAttempt so a read failure is handled separately from a verified stale
attempt: report that the order was applied and direct the cashier to the payment
queue, without clearing the cart or showing the response ticket. Only apply the
ticket response or clear the cart after a trusted read or independent
correlation check confirms this attempt is still current; do not treat an
unreadable retry state as proof that it is current.
Review comments at @frontend/src/lib/i18n/messages/ar.json:
- Line 1802: Update the Arabic counter wording in counterLoadFailed and the
related new empty-state messages to use محطة consistently instead of العدّادات.
Review comments at @frontend/src/lib/i18n/messages/tr.json:
- Line 1763: Update the Turkish addFirstCounter message to use the existing term
banko instead of sayaç, including the corresponding plural-counter wording, so
it matches the terminology used in settings.
Review comments at @main/printers/thermal.ts:
- Line 1454: Wrap storeName to fit the printer’s column budget before adding it
to the lines collection in the header-building flow, keeping each resulting line
centered and bold so the full merchant name prints without truncation.
- Around line 1498-1499: Update the Total and Balance Due rendering around the
lines.push calls so each amount moves to its own right-aligned line when its
label and amount cannot fit within the ticket width; reject any amount that
cannot fit on its own line.
