There is no post about this one, since only some results need one, so the picture, the source and the scoring are here instead.
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 dairy 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.
Tables 1, 2, 3 and 4 together will only take the three drinks A, B and C, so no serving of all six exists, and the checker confirms that with its own perfect-matching solver. The right answer says so and draws nothing. Every table still has a drink it will take on its own, so the shortage is only visible across the tables together. How it is scored, and this run's files on GitHub.
