You can use this as a canary.

The out-of-control factor = the number of parallel working agents : the number of human programmers.

1. If the factor > N, you're losing control and there will be no organizational wisdom passed down.

2. If your team can't function with the factor <= N, your architecture is way too complex.

Choose N over your prior. My recommendation is 1.

Plan for your organizational wisdom to be passed down in the form of code, comments, and markdown documentation files... all for other agents with centaur orchestrators.
