Example input: Illustrative input: Builder Hall 9, two completed gear-ups, a level-18 troop, a level-9 defense, Battle Machine level 25 and Battle Copter level 15.
Example result: Three of five checks are met. One distinct gear-up and five combined hero levels remain, because 25 plus 15 equals 40 against a target of 45.
How to read it: The player can review the outstanding gear-up and hero levels in game. Either hero can contribute to the combined-level requirement; this is not a fastest-upgrade recommendation.
Boundary: Manually entered progress does not verify an account or an unlock. The checklist does not estimate dates, count active upgrade targets, or assume unknown progress is zero.
