Parker EarthShield follows a planetary stewardship model: UN-chartered oversight with scientific transparency, a multilateral governance board with Global South representation, real-time public data access, and hard reversibility clauses. Deployment must serve humanity as a whole, guided by precedents from the Antarctic Treaty, ISS, and IPCC.
