This release concerns the Polydegree Conjecture, a problem about how families of polynomial transformations of the plane fit together at their boundaries. Earlier work reduced many cases to an explicit algebraic test: several coefficient polynomials must vanish, while another coefficient and an auxiliary determinant remain non-zero. The main observation here is that the auxiliary determinant is not a separate mystery. Up to sign, it is the Jacobian determinant of the coefficient polynomials already in the problem. A Jacobian detects whether equations meet cleanly, so the test can be read geometrically: find one smooth point of the intersection that avoids the next forbidden hypersurface. An exact weighted-Euler identity makes that translation integral and leads to a smaller finite-field certificate. A simple modular zero with a non-zero next coefficient can be lifted to characteristic zero, including some primes rejected by the older determinant-unit test. The paper also proves a curve-based route to the same point and a uniform squarefreeness theorem for each individual boundary polynomial in the three-variable family. Exact calculations show the full affine property for indices two through twenty, and adjacent boundary coprimality through two hundred. Those finite ranges are not a proof for every index. This is an anonymous, unrefereed candidate. The public package contains the paper, exact evidence, manifest, replay scripts, negative controls, and review records. Producer replay has passed, but there has been no independent reconstruction, formal verification, external specialist review, or journal peer review.
