Anonymous unrefereed three-paper candidate bundle. The principal paper proves the full e=4 Polydegree containment for every integer d >= 2 using published low-degree input, an exact residue class, 14,985 outward-rounded FLINT/Arb certificates, and an explicit eventual analytic branch. Companion papers provide a Lean-checked universal bordered-Jacobian identity over arbitrary commutative rings and a conditional finite-pencil boundary-norm transfer theorem. Producer-side replay and internal AI editorial review are recorded. Independent reproduction, external specialist review, journal peer review, Furter R(3), JC2, and HC4 are not claimed.
