Good. Do these without looking anything up: 1. Explain designing idempotent background jobs in two sentences. 2. Give one situation where you would use it and one where you would not. I am checking your current model, not your vocabulary. A partial answer is more useful than a polished guess.

Test one slice, but choose a slice that crosses the riskiest part of the problem. A tiny easy demo will only prove the easy part. Use this decision rule: - If reversing the choice is cheap, try it. - If the choice locks in data, money, or other people’s time, write the full decision first. - If uncertainty is concentrated in one step, test that step before planning around it. For prompting from examples, make the first test produce evidence you can compare, not just something that looks complete.

This is usable as written. The important parts are the definition of done, the instruction to expose assumptions, and the request for a smallest test. For a budget after three weird months, I would start with these checks: - Separate known amounts from estimates - Compare total cost, not the monthly number - Keep a conservative case If you share real material, remove anything private first and replace bracketed fields with concrete details.
