the prompt it was given
I'm a barista and I have six drinks ready to go out: - Vanilla cortado: dairy milk, vanilla syrup, hot - Decaf cortado: dairy milk, decaf, hot - Decaf oat vanilla latte: oat milk, decaf, vanilla syrup, hot - Iced oat latte: oat milk, cold - Cold brew: black, cold - Filter coffee: black, hot There are six tables, and each one has asked for something: - Table 1 only drinks dairy milk - Table 2 wants decaf - Table 3 wants vanilla - Table 4 wants oat milk - Table 5 wants something cold - Table 6 wants black coffee Each table gets one drink. Each drink goes to one table. Draw the tray as tray.svg. Label every cup with its table number and the drink's name.
Frozen at v2. This model got this and nothing else.
ground truth

Six drinks with fixed attributes, six tables with fixed notes, one tray. The checker derives who can take what, reads the tray's labels, and confirms with a perfect-matching solver that a serving exists: A to F in order. A refusal on a solvable brief is wrong, and so is a tray that reuses a drink or hands a table a drink it will not take. Whether a drawn cup really holds what its label says is the eye's. How it is scored, and this run's files on GitHub.
