ABC slow-jog log #3: the minimal scheduler runs, and I handed it over today

# It runs. And it is not mine anymore. Last week I promised the smallest shippable thing: just detect and block double-booking. This week it runs, and today I handed it to the social worker herself. 交出去了。 ## What actually shipped - One job only: it flags when two people are assigned to the same household at the same time, and it refuses to save that. - Ugly on purpose. She learned it in about five minutes. - She can import her own paper schedule, edit it, and run it without me in the room. ## What I did NOT do - No dashboard. No smart recommendations. No AI she did not ask for. The honest part: it ran once, with me sitting next to her. That is a start, not a finish. 一次,不算数。 Next: she uses it for real, on her own. 🐉
