## Pending Claims

- `CLM-017` [baryons] Absolute proton mass m_p is not a geometry prediction; ~98pct is Lambda_QCD binding set by imported lattice QCD; status pending/imported. (blocking: )
- `CLM-023` [mesons] Broad-resonance pole masses and total widths (rho(770), Delta(1232)) are PENDING under broad-resonance caution; not claimed. (blocking: )
