Evidence boundary

This target indexes Mathlib's prime-ideal Eisenstein criterion for a polynomial over a commutative integral domain. The conclusion requires a prime ideal P, positive degree, primitivity, leading coefficient outside P, every coefficient strictly below the degree inside P, and constant coefficient outside P². It concludes irreducibility in R[X]; it is not an unrestricted prime-element or algorithmic criterion.
