// TestEd25519Vectors runs a very large set of test vectors that exercise all
// combinations of low-order points, low-order components, and non-canonical
// encodings. These vectors lock in unspecified and spec-divergent behaviors in
// edge cases that are not security relevant in most contexts, but that can
// cause issues in consensus applications if changed.
//
// Our behavior matches the "classic" unwritten verification rules of the
// "ref10" reference implementation.
//
// Note that although we test for these edge cases, they are not covered by the
// Go 1 Compatibility Promise. Applications that need stable verification rules
// should use github.com/hdevalence/ed25519consensus.
//
// See https://hdevalence.ca/blog/2020-10-04-its-25519am for more details.
