   The checkout total is wrong

   Customers were charged the wrong amount on Monday. Fix the pricing against the rules and work out who's owed what.

   Hi, welcome to the checkout team! Your first job is a live one, sorry. Support has had a morning of customers saying they paid the wrong amount yesterday, Monday 19 October, and finance says Monday's takings don't match what our pricing rules should have produced. Arjun changed the pricing code last week and he's on leave until Thursday. His tests all pass, which tells us the tests don't cover much. The download is the checkout service as it ran on Monday, with every order we took that day and what each one was charged.

   Why are users being logged out?

   People keep getting signed out of the app. Read the auth service and a day of its logs, and find out which sign-outs were bugs.

   Morning, and welcome to Platform! You've landed in the middle of something. Since yesterday, Wednesday 21 October, people have been writing in saying Paylark keeps signing them out: mid-payment, on the bus, twice an hour. Some of those sign-outs are the service doing its job. Some aren't, and those are the ones I need you on. The download is the auth service as it ran yesterday, with the whole day's logs from all three auth servers. Before we change anything, I want to know exactly what happened:

   Pull the partner's data properly

   The job that syncs shipments from a carrier's API prints the wrong numbers. Make it survive the API and get ops the real ones.

   Hey, welcome to Integrations! Ops review October with Trukvo, our biggest carrier, on Friday. Our intern wrote a small job that pulls our shipments from Trukvo's API and prints the numbers ops want. It runs, it prints numbers, and ops say the numbers don't match what they see in Trukvo's portal. I trust the portal. The download is the job, with our sandbox key for Trukvo's API already in .env. The sandbox serves the same data as live. I need, by tomorrow:
