Challenge statement

Hubble tension — see briefing 01 §7 for full structural framing.

Why this challenge is in the ledger

Migrated from v1 problem-ledger entry phys-hubble-tension. Per briefing 01 §7, classified as ring R2_quantitative_falsification in cluster cosmology-dark-sector with physics-core-weight core.

Bibliography clusters whose prior art bears on this page. Each cluster links to its representative references and to the broader Deep Comparison briefing.

First reviewer questions

  1. Does τ produce extensional results for Hubble tension?
  2. Is the assigned cluster + ring depth structurally accurate per briefing 01 §7?
  3. Should this item carry cross-domain links (Wave 6 wires those)?
