which sa is ies ∇µTµν = 0 and sou ces p ecisely he me ic unc ion ( )in (2).

The FCI (Fundamen al Conse a ion o In o ma ion) p inciple equi es ha no p ocess,
g a i a ional o o he wise, des oys in o ma ion—only eo ganizes i . Because he RCFT-
sou ced Haywa d me ic elimina es cu a u e singula i ies, he in o ma ion encoded in he

Thus:

which sa is ies he FCI condi ion. The black hole in e io becomes an in o ma ion-p ese ing
