Four principles behind brain

What the product is built around.

Context is code. Treat it and manage it like code.

It has versions, owners, dependencies and a review path, or it drifts into five copies that no longer agree.

Context is a team sport.

Skills built by domain experts need to be shared across the company.

Your context is your IP.

Models change. Harnesses change. What your company knows about how it works should outlive both, and it should not belong to whoever you bought your stack from.

Context is a living, compounding system.

Every trace is a signal that can improve context over time.
