Challenge statement
What is physically meaningful without an external observer, fixed background, or hidden coordinate frame?
Why this challenge is in the ledger
τ-native physics structural challenge from briefing 01 Appendix A. Tests what is physically meaningful without an external observer, fixed background, or hidden coordinate frame?
τ-facing burden
Per briefing 01 Appendix A: What is physically meaningful without an external observer, fixed background, or hidden coordinate frame?
First reviewer questions
- Does τ produce extensional results for this challenge?
- Is the framework's response auditable rather than only asserted?
- What would count as failure?
