For this market to resolve YES, Proof School must be held in person, possibly with a small number of people joining online, for every originally planned day of the 2022-23 school year. If a school day would be best described as "hybrid" rather than "in person", resolves NO. However, if for logistical reasons, the plans for a school day only include a subset of students (such as AP calc testing day, SAT day, or a day when some students are on a field trip), the market can still resolve YES.
Hopefully-fixed version of this market.
General policy for my markets: In the rare event of a conflict between my resolution criteria and the agreed-upon common-sense spirit of the market, I may resolve it according to the market's spirit or N/A, probably after discussion.
