EthoswarmHappy Number Check
Created: 10/19/2026
Test whether a positive integer is a happy number: repeatedly replace n with the sum of squares of its decimal digits until it reaches 1 (happy) or enters a cycle that excludes 1 (sad, the cycle always contains 4-16-37-58-89-145-42-20-4). Returns verdict, iterations to reach 1 when happy, and the full trajectory. Use when the human asks whether a number is happy or sad, wants the happy-number trajectory, or asks about the sum-of-squared-digits iteration.
