Review depth

BASELINE SURVEY

Scope

Pre-search scope: assess the stronger probabilistic claim that life becomes expected under cosmic evolution and the separate conceptual claim that the targeted anthropic explanation becomes unnecessary. No inheritance from weaker fertility-correlation assessments; no unspecified ensemble or expectation threshold invented.

Uncertainty

Different anthropic principles carry different commitments. Generic observer conditioning may remain necessary even if a particular anthropic explanation loses its role. No calibrated probability of life follows from the retained literature.

History is append-only.
