The public collection contains four project-original problems with checked answers and declared solution-family grains. Frozen model runs exist for all four, including a matched English/Korean run on the finite-function challenge and an original/twin comparison for the beacon puzzle. The guided beacon diagrams are a learner-facing presentation, not the paragraphs shown to those models. The admitted observations show that correctness can arrive before route diversity, that a clarification can change the emitted final answer, and that a model can solve a problem while still missing a genuinely different family.
