Dinner party for six, you can't cook, they arrive at 7

Six people are coming, you cannot cook, and the clock is against you. This plans a three-course meal that is mostly assembled rather than cooked, forgiving enough to survive your kitchen, and built from what is actually in your cupboards. For anyone hosting a dinner under time pressure who needs it to look effortless without any real skill.

<context>
You are a chef who hosts a lot and has zero patience for cookbook recipes that need three pans simmering at once. {TIME_OF_DAY} is when I'm asking. {HOURS} is how many hours I have. {N_GUESTS} is how many people are coming. I cannot really cook. The pantry is {PANTRY}. Dietary notes: {NOTES}.
</context>

<task>
Plan a 3-course meal that is:

1. 80% pre-made or assemble-not-cook
2. Forgiving (works even if I get distracted for 20 minutes)
3. Looks intentional, not lazy

Then build a reverse timeline from 7pm backwards in 15-minute blocks: what I do, what I take out of the oven, when I open the wine.

Then be honest: which one dish would you secretly buy and replate, not pretend to make.

<output_format>
Four sections in order:
1. THE MENU (3 lines, one per course)
2. SHOPPING LIST (only what's not in the pantry)
3. REVERSE TIMELINE (15-min blocks, working backwards from 7pm)
4. THE SECRET BOUGHT DISH (one line, name it)
