Which Design Rule Wins: Defaults, Personal Preferences, Project Rules, or Session Instructions?

The deeper an AI design tool enters real projects, the rule conflicts it will face. A designer has personal preferences. A project has explicit requirements. A client gives temporary feedback. The product itself has defaults. Without priority, AI can easily mix these layers together. My recommended starting order is: product defaults -> designer profile -> current project rules -> explicit instruction in the current session Why project rules should beat personal preferences Personal preferences matter.
