The principle arc introduces the operating model that the rest of the series develops. Two posts establish controlled exposure as the right principle for publishers operating in an AI-shaped environment, then develop publisher-controlled access as the operating model that follows from it — the three-layer publishing structure that decides what leaves the building, to whom, and on what commercial terms.
These posts are the structural hinge of the series. Everything in the capability arc is what the operating model makes possible; everything in the monetization arc is how the operating model gets paid for. Read this arc to understand how the rest of the series fits together.
