SE Press: Life is an autocatalytic, feedback-amplifying instability—statistically plausible, but not cosmically inevitable nor purpose-driven. All existential claims are protocol-scored, empirically auditable, and version-locked for upgrade as astrobiology, SI, and entropy insights evolve.

SE Press: Ingredients and conditions for life are abundant across the cosmos. This protocol-scored framework benchmarks biosignature plausibility for planets and moons, integrating LifeScore, ComplexityScore, and ExistentialRisk. All claims are evidence-based, challenge-ready, and upgradeable as science advances.
