  "abstract": "A bstract : We formulate a local semiclassical source-response prescription for derivative-free stress-tensor deformations in dS/CFT. The metric flow determines the deformed boundary metric and stress tensor, encoding the deformation through mixed boundary conditions at future infinity. In Kerr-dS ₃ /CFT ₂ , the holographic charges reproduce the field-theory spectral flow, providing an internal consistency check. For general deformations in this class, we derive a holographic pseudo-entropy formula in terms of the flowed boundary data, nonperturbative in the deformation parameters within a specified complex-geodesic prescription. We evaluate this formula explicitly for the $$ T\\overline{T} $$ T T ¯ and root- $$ T\\overline{T} $$ T T ¯ deformations. On the non-rotating principal branch, an analytically continued replica calculation reproduces the interval-dependent corrections at first order in the couplings and at leading semiclassical order. Agreement of the interval-independent terms additionally requires a source-frame regulator identification.",
