Corrections & publication log

A correction should explain what changed.

October 24, 2026 — Initial publication

Published the launch collection of 16 quizzes, six notebook articles, four category guides, and an exhaustive scoring experiment. The experiment includes 1,024 constructed answer patterns and a reproducible script. Dates reflect this launch rather than a fictional earlier archive.

Content corrections

October 24, 2026: clarified questions 1 and 5 in Can you spot the missing clue?. The book question now explicitly names all three books; the counter question now states that at least three counters are available. The answer keys are unchanged. These additions make the assumptions explicit. Future substantive corrections will be recorded here; routine layout changes are not described as factual corrections.
