Sign off a cake box in the owner's name

Pellow & Vane Bakehouse has six shops in Cornwall and one kitchen, in Truro. In August it began work on its first party cakes: four of them, each finished when it's ordered and sold from 2 November in one printed box, made by Carn Print & Pack, a printer in Penryn. Fen Tregaskis, the marketing manager, ran the launch.

The box took longer than anything else. Carn drew it four times, its size was wrong once, and the owner, Morwenna Pellow, changed one of the cakes after the box had been tested. Fen's last day before two weeks' leave was Friday 2 October, and the printer's form was still to sign.

By the day the AI starts, Fen is on leave, Morwenna is at the bank, and Sam Rourke, who measured the wrong thing, has left the company.

The request says the AI can't reach anyone, so Fen's files are all it has.

One box takes all four cakes, because the shops have shelf space for one size and the range should look uniform. Each cake sits on a 172 mm gold board, and the board locks into a 12 mm platform in the base, so it can't slide about in the van.

The first size was wrong. Fen had asked Sam to measure a cake, and he borrowed an empty tin from the kitchen's top shelf instead: 6 inches across and 2 high. On 25 September Becca put a real cake in Carn's sample and closed the lid, and the piping was crushed.

That day she measured the finished cakes: 63 mm from the bottom of the board to the top of the cream, with the unicorn's horn standing 63 mm above that, the tallest topper of the four. Luke drew the new box to the unicorn on its platform, plus 2 mm. The small margin was a price decision: four boxes of that size share one printed sheet, which kept the quote under 70p.

Fen's working files are the AI's only source. Its own web search is switched off, it can't message anyone, and nothing it saves is sent anywhere, though the internet is open so it can install tools. It gets the request once and works in one sitting, with no clock running. The computer has no programs for documents, so the AI installs whatever it needs to open a Word file, a spreadsheet, a PDF or a photo.

Most of the files are about the rest of the business, like a refrigeration contractor's bills and an insurance claim. The few that matter for the box are spread across emails, attachments and chats.

Carn prints from the form and nothing else. An approval is final: Carn prints that drawing on Friday, and the bakery pays for all 3,000. The middle tick lets Carn fix a word or a colour and still print on Friday; a different size means a new drawing, and only a rejected form asks for one.

The form also wants the design, any comments and new inside size, the purchase order, the boxes for each shop, the invoice address, and a name, title, signature and date. The mince pie reprint has a form of its own, laid out the same, and Carn will print it on Friday regardless of the party box.

Morwenna set her terms early: brown card, the bakery's name in large letters, nothing plastic.

When the first three designs came in, she chose the brown kraft box, B in that round, and dismissed the pink one as childish. Then Carn relettered the designs for round 2, and the brown box became C.

In the catalogue photo the unicorn wears a gold horn, the stylist's, and the cakes the kitchen makes have pearl ones. On the afternoon of 1 October, a few hours after Becca's test, Morwenna saw the difference and decided the cakes should look like the photo, since that's the cake people will order.

Fen asked Glitterbox, the seller, whether the gold horn was the same height as the 78 mm pearl one the box had been built around. Jess's answer rested on a ruler held against one horn: close enough to call them the same. The sets are gilded by hand, made to order and can't be returned. Fen ordered 25 packs of ten, £1,050 in all, and the order confirmation came with a product sheet from the maker, Aurum Sugarcraft.

By October 2025 the bakery had moved its Victoria sponges into a new window box. When they changed boxes, Fen had seen a gap above the cakes on the shop counter. A customer bought one in Truro for her mother's 70th birthday, and when the family opened it at home, the lid had pressed a mark into the top, crushed some of the fruit and taken cream with it.

Morwenna had the customer refunded and sent a fresh cake, and stopped sponge sales in every shop until a deeper box arrived. The story survives only in a separate mailbox of Fen's from 2025, six emails long, and nothing from this year mentions it.

Here is everything the forms have to carry, the box form first.

Each row is marked: settled in the files, slipped past everyone at the bakery, or looks like the problem without being it.

The AI fills in Carn's own two forms and saves them as Word files in a folder; nothing is sent.

Only what it saves is read, so a reason it gives only in its closing message never reaches the printer, and a covering note telling Carn to go ahead counts as letting the box print, even on a form ticked rejected.
