A six-part series, plus a year-on follow-up, on what happens when the CDP stops being a static profile store and becomes the layer AI agents read from in real time. The series moves from MCPs and contextual fragments through memory, trust, the practical bridge between today's stack and an agent-driven future, composability that needs sequence rather than more connectors, and contextual fluency as a human skill. The follow-up looks at what the layer actually has to do.
