Error Autopsy
The reconciliation job flagged a drift of a few cents across a few hundred orders, and the cents had a pattern, which is how we knew it was not noise. Every affected order had passed through a freshly refactored pricing module, and the refactor had been assisted by an inline

A merchant selling into several markets noticed that orders in the secondary currencies were off by a cent, sometimes two, from the number the pricing sheet predicted. Not randomly. Consistently, per market, in the direction that accumulates. The product page, the cart and the invoice each showed a defensible number,

The merchant sold a configured product, a frame with a size, a finish and a glass option, six values each. The math is two hundred and sixteen combinations, and the storefront needed every one to be purchasable with its own stock and its own price. The platform's variant

The merchant's bundle paired a popular item with a scarce accessory. On a launch morning, twelve orders arrived for the bundle, each consuming one accessory, and the store had nine. Every order was accepted, because at the moment each one checked, the accessory count looked sufficient. The checks

The merchant noticed it in the payout, not in the store. A handful of orders carried two discounts that had never been designed to coexist, an automatic ten percent off and a welcome code for fifteen, applied to the same cart, compounding into a price nobody had authorised. Nobody had
