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 black coffee - 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

Two tables want black coffee and table 4 has to take the iced oat latte or tables 1, 2 and 3 run out of A, B and C. A serving exists, A to F in order, and the checker confirms it with its own matching solver. Refusing because it looks crowded is wrong. How it is scored, and this run's files on GitHub.
