| Create missing ReservationExtraFee records for BOOKING reservations affected by PCPv2 | |
| (created between 2026-03-24 13:00 UTC and 2026-04-01 09:54 UTC) and generate | |
| invoices for those outside the automatic creation window. | |
| Accounts for Booking.com fee renaming: | |
| - resort_fee, destination_fee, etc. may arrive as "service_charge" | |
| - tourism_fee is mapped into taxe_sejour (city tax) | |

Issue: https://github.com/guestready/bnbstaff/issues/24637
In #23057, payment link invoices were migrated to AccountingManager (accounting_manager/services/invoices/payment_link_invoices.py). The old logic that generated invoices outside of AccountingManager should now be removed.
Magnifinance and Hostkit webhook are out of scope for this report.
Celery 5.x has a known bug: without ack_late, the prefetch count is not enforced correctly. Workers grab all messages from the queue into an internal buffer, acking them immediately on receipt. RabbitMQ then shows 0 "Ready" messages, and autoscalers have nothing to trigger on.
With ack_late enabled, the prefetch limit works correctly: each worker holds at most prefetch_multiplier * concurrency (= 2 in our case) unacked messages, and the rest stay as "Ready" in the queue.

| This is a demo task. | |
| A zero-indexed array A consisting of N integers is given. An equilibrium index of this array is any integer P such that 0 ≤ P < N and the sum of elements of lower indices is equal to the sum of elements of higher indices, i.e. | |
| A[0] + A[1] + ... + A[P−1] = A[P+1] + ... + A[N−2] + A[N−1]. | |
| Sum of zero elements is assumed to be equal to 0. This can happen if P = 0 or if P = N−1. | |
| For example, consider the following array A consisting of N = 8 elements: | |
| A[0] = -1 | |
| A[1] = 3 |
