A.6.3.RT:12b - C.29 mathematical-lens use relation
When RT imports a contested or claim-bearing mathematical lens, RT still carries source/target schemes, same-EntityOfConcern construction, preservation, loss, and return. Cite the applicable C.29 output only for adequacy of that mathematical lens. C.29 neither replaces the RT account nor broadens it into bridge, evidence, or causal authority.
