External: externally open
τ response: further investigation
Is life necessarily carbon-based, water-based, cell-based, and Earth-biochemical, or are there substrate-independent structural invariants of life?
Current τ response

Challenge statement
Is life necessarily carbon-based, water-based, cell-based, and Earth-biochemical, or are there substrate-independent structural invariants of life?
Why this challenge is in the ledger
The Life layer claims to define life structurally, not merely to catalogue terrestrial organisms. Non-carbon, non-water, and nonterran possibilities test whether this claim is substantive.

τ-facing burden
Separate structural invariants from Earth-specific implementations. Identify which features are mandatory for life as such and which are contingent realizations.
First reviewer questions
- Does τ produce extensional results for substrate independence and nonterran life challenge?
- Does the framework distinguish promotion from re-description?
- What external review would settle the open questions?
