No card ships until a blind judge passes it

The developer of the puzzle app Keyhole has implemented a rigorous, automated quality control system to ensure the integrity of its 296 illustrated dark stories. To prevent spoilers and ensure visual accuracy, the creator established a 'blind judge'—an AI model that evaluates cards without knowledge of previous failures or specific design briefs. This process forces the system to grade the final output objectively. The developer utilized a multi-wave feedback loop where briefs were iteratively refined based on the judge's rejections. This approach proved that the brief itself is the most critical lever for success, rather than simply re-rolling image generation. By separating the roles of writer, illustrator, and judge, the developer successfully created a gatekeeping mechanism that ensures no card contains spoilers or logical inconsistencies, providing a reliable standard for the app's content before release.
