Variance Suppression by a Numerical Wave Cap in Ultralight-Dark-Matter Strong-Lensing Simulations: Exact-Commit Audit of a JWST Survey-IV-Derived Forward Model, with Realization and Selection Diagnostics
Strong-lensing inference with ultralight dark matter (ULDM) can depend on stochastic wave-field realizations and numerical controls used to make those realizations computationally tractable. This work performs an exact-commit audit of the public pyHalo/samana/lenstronomy software ecosystem used in a JWST Survey-IV-deri...
