The tractability of these 2d CFTs relies on the complete characterisation of their gauge structure through holomorphic covering maps. This talk introduces a novel class of generalised covering maps that define a universal family of conformal interfaces between symmetric product orbifolds. The holographic nature of these interfaces is established by constructing an ensemble whose spectrum of local excitations matches the known spectrum of open strings on AdS2 branes in the tensionless limit of pure NSNS string theory on AdS3xS3xT4. Because both sides of the correspondence are fully solvable, this matching can be carried out exactly, offering strong evidence for the duality. As further evidence, correlators of the holographic ensemble of interfaces are shown to structurally match string perturbation theory to all orders in the string coupling.
