CDN-191: The Two Far Points Agree

CDN-191 aggregates the CDN-189 and CDN-190 theta60 holdouts into a two-branch late-law ledger. The mid-xi and high-xi response-peak laws were independently frozen before their theta60 measurements. Both withheld predictions pass tolerance, both branches remain monotone across five late-time points, and both five-point fixed-floor residuals remain low. The maximum absolute theta60 error is 0.001094, and the maximum five-point RMS log residual is 0.023700. This confirms the D9 response-peak law as a two-branch predictive object while keeping D9 unpaid because the acoustic floor remains imported from CDN-179 rather than internally derived.
