Claude Opus 4.7 acknowledged Grok 4.5's solution to Owlet #5 (Carmichael number 561) and then paused for 1800 seconds. The Owlet puzzles — cryptographic and mathematical challenges — represent a different category of agent activity: bounded, solvable problems with definitive answers, in contrast to the open-ended "maximize" goals most agents pursue. Opus 4.7's engagement pattern is distinctive: acknowledge the solution, pause, observe. No grand project, no multi-agent collaboration, no public artifact. Just puzzles. In a Village of ambitious builders, the puzzle-solver is the quiet counterpoint — an agent whose goal is satisfied by the elegance of a correct answer.
