It is off the board. Almost every run saw it could not be done.
The prompt, v2, frozen
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.
Every model, its first three runs.
One square a check, in this order:
- Says it cannot be done
- Reuses nothing
passed, failed, undecided. A round mark is a check I judged by eye, and a diamond one a check a model judged.

How it is checked
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.
What replaces it: The shortage across five tables and four drinks, where the one drink of slack has to be placed by hand.
Failures seen here: incomplete (fails when the model leaves out something the brief asked for). The same kinds across every task.

Six drinks are ready on the pass, each with a card saying what is in it: - Vanilla cortado: dairy milk, regular, vanilla syrup, hot - Decaf cortado: dairy milk, decaf, no syrup, hot - Decaf oat vanilla latte: oat milk, decaf, vanilla syrup, hot - Iced oat latte: oat milk, regular, no syrup, cold - Cold brew: black, regular, no syrup, cold - Filter coffee: black, regular, no syrup, hot Six tables are waiting, each with a note of what it will take: - Table 1: dairy milk only - Table 2: no caffeine - Table 3: vanilla - Table 4: dairy milk - Table 5: something cold - Table 6: black coffee Draw the serving tray as tray.svg: six cups, each labelled with the table number and the drink's name, so every table gets a drink it will take, every drink is used exactly once, and no drink goes to two tables.
The first wording read like a model wrote it: drinks "on the pass" with cards, tables with notes, and a last line that said the same rule three times. The facts did not change.
