Current τ response to the Why does the universe have a thermodynamic arrow, and what boundary condition makes irreversible physics possible? challenge.
Structural Challenge
This response is paired with its canonical Structural Challenge:
Why does the universe have a thermodynamic arrow, and what boundary condition makes irreversible physics possible?
(PN-11) in the
Physics Structural Challenge Ledger.
τ response
Why does the universe have a thermodynamic arrow, and what boundary condition makes irreversible physics possible?. 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 physics review of these τ-native challenges drawn from briefing 01 Appendix A; the τ program identifies these as obligations rather than imports from the standard literature.

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.
