Current τ response to the What Is Life as a Structural Class? challenge.
Structural Challenge
This response is paired with its canonical Structural Challenge:
What Is Life as a Structural Class?
(LIFE-SC-01) in the
Life Structural Challenge Ledger.
τ response
Show that Life = Distinction + SelfDesc is not merely a slogan. The framework must demonstrate that the two predicates recover the classical hallmarks of life, generate useful phase boundaries, and make biological structure legible without reducing life to an arbitrary list. Mapping to current τ work pending fresh registry curation.
Evidence route
No canonical registry items currently mapped to this challenge. Mapping pending τ-native or further-investigation curation.
Notes
Verification
External-review boundary
External philosophical / theoretical-biology review of the τ definition of life and its categorical bridge; comparison with chemoton, autopoietic, NASA, and information-theoretic definitions.
