The repo's .ai/why/ does not contain the "why" behind the project. It provides a list of dozens of small decisions the agent presumably made as part of implementation; none of them explain what a "why-pack" is, or describe their underlying structure and principles, or detail the thought process behind the decision that "why-packs" are the best strategy to achieve the project's goals.

I would encourage you to treat AI outputs with substantially more skepticism than you're giving them.
