Current τ response to the Substrate Independence and Nonterran Life Challenge challenge.
Structural Challenge
This response is paired with its canonical Structural Challenge:
Substrate Independence and Nonterran Life Challenge
(LIFE-SC-08) in the
Life Structural Challenge Ledger.
τ response
Separate structural invariants from Earth-specific implementations. Identify which features are mandatory for life as such and which are contingent realizations. 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 origin-of-life / astrobiology review of the τ formulation; comparison with prebiotic chemistry, hydrothermal-vent, and 'life as it could be' programs (synthetic biology, xenobiology).

Status disclaimer
A Challenge Response reports the program's current internal stance against a canonical Structural Challenge. It does not imply external verification, scientific consensus, philosophical settlement, or final proof. Read it together with its evidence route, registry references, verification status, and external-review boundary.
