Abstract
We prove quenched chordal SLE3 convergence for the planar Ising model with sufficiently weak independent symmetric two-valued ferromagnetic bonds. The temperature is the critical point defined by spontaneous magnetization. Convergence holds in probability over environments for the full oriented curve law in deterministic Jordan-domain approximations.

- M. Gallone and V. Mastropietro, Universality in the 2d quasi-periodic Ising model and Harris-Luck irrelevance (arXiv:2304.01736, Commun. Math. Phys. 405 (2024) 235). A rigorous renormalization-group proof that weak quasi-periodic coupling disorder leaves the 2D Ising critical behavior unchanged; it is a point of comparison for the paper's claim about weak symmetric two-valued iid bond disorder.

Perturbative and numerical study of interface fractal dimensions in weakly bond-disordered Potts models; it bears on the paper's quenched SLE₃ interface theorem.
- A. L. Talapov and L. N. Shchur, Critical Point Correlation Function for the 2D Random Bond Ising Model (arXiv:hep-lat/9404002, 1994). Monte Carlo evidence that the critical spin correlation with ferromagnetic impurity bonds is numerically very close to the pure one; it gives numerical background for the marginal-irrelevance picture the paper relies on.

Family 218: Conformal universality for weakly interacting and random-bond Ising models
Weak finite-range square-symmetric even multispin perturbations of the square-lattice Ising model preserve critical bulk spin and energy limits; weak square-symmetric contour interactions also yield chordal SLE3 interface limits. With sufficiently weak iid bond disorder of any fixed bounded nondegenerate mean-zero law, critical spin interfaces converge to the same law in probability over environments.
