Challenge statement
Ultra-high-energy cosmic ray — see briefing 01 §7 for full structural framing.
Why this challenge is in the ledger
Migrated from v1 problem-ledger entry phys-ultra-high-energy-cosmic-ray. Per briefing 01 §7, classified as ring R5_peripheral_observational in cluster astrophysics-cosmic-systems with physics-core-weight peripheral.
First reviewer questions
- Does τ produce extensional results for Ultra-high-energy cosmic ray?
- Is the assigned cluster + ring depth structurally accurate per briefing 01 §7?
- Should this item carry cross-domain links (Wave 6 wires those)?
