+extraction_notes: "Extracted two major claims about MA's policy-contingent growth and the ideological shift in MMA 2003. Enriched four existing claims with historical context about payment policy cycles, risk-bearing incentives, attractor state misalignment, and Devoted's growth in context of quality bonuses. The BBA 1997-MMA 2003 crash-and-rescue cycle is the key extractable insight—it demonstrates that MA viability depends on above-FFS payments, not market efficiency or consumer preference. The ideological reframing from cost containment to market accommodation explains why overpayments have been sustained for two decades despite consistent evidence of inefficiency."

 PRIMARY CONNECTION: [[the healthcare attractor state is a prevention-first system where aligned payment continuous monitoring and AI-augmented care delivery create a flywheel that profits from health rather than sickness]]
 WHY ARCHIVED: Essential historical context — you can't evaluate where MA is going without understanding the political economy of how it got here.
 EXTRACTION HINT: The 1997-2003 crash-and-rescue cycle is the most extractable insight. It demonstrates that MA's growth is policy-contingent, not demand-driven.
