Regular Black-Bounce Solutions with Electromagnetic Sources: A Non-Linear Electrodynamics Approach (Version 2.0)

Version 2.0This version provides a fully revised and technically consolidated formulation of the Shielded Regular Unified Framework (S-RUF).Major improvements include:– corrected and explicit derivation of curvature invariants,– refined treatment of nonlinear electrodynamics sources,– clarified regularity and energy condition analysis,– improved consistency with the Reissner–Nordström limit. This version supersedes v1.0 and should be considered the reference version of Article I.
