This preprint derives the electron mass from topological string tension in the framework of Energy String Field Theory (ESFT). With one fitted coherence scale and one topologically derived string-tension scale, the manuscript reproduces the electron mass and develops twenty-three further parameter-free quantitative predictions across multiple physical sectors. The work is released as a public preprint for citation and scholarly reference.
