Review depth

BASELINE SURVEY

Scope

Bounded existential capacity: astrophysical production, energy supply and planet-forming chemistry; distinguish enabling conditions from life sufficiency. Four independent primary evidence/model families.

Uncertainty

Pathway yields, transport efficiency, local persistence and biological consequences require separate quantitative questions. This pass samples representative enabling routes, not all cosmic environments.

History is append-only.
