🔴 Maintainers get no test that catches the public-key half of the new filter being removed: every new case still passes, so a regression would re-admit the forgery from #46252. Each small-order-key case pairs the key with a small-order R (identity or the same point), so the R clause at ncrypto.cpp:3717 alone rejects it. Fix: add a case under a small-order key with an ordinary R that only the publicKey clause rejects, e.g. key 01 00..00 with signature R = 5866666666666666666666666666666666666666666666666666666666666666, S = 1, any message, expecting false; cover the one-shot, callback and subtle.verify paths. Same pattern at web-crypto.test.ts:595, web-crypto.test.ts:625, crypto.key-objects.test.ts:1882. [also at: test/js/web/crypto/web-crypto.test.ts:595 - Maintainers get no test that pins the public-key half of the new check: a build that drops the key clause still passes every new test.]

Why this was flagged

The filter in src/jsc/bindings/ncrypto.cpp:3717 has two load-bearing clauses: reject a small-order R and reject a small-order public key. Every new test uses a small-order R: crypto.key-objects.test.ts:1857 and web-crypto.test.ts:595 sign with zeroSignatureWithR(ED25519_IDENTITY) (R = identity), the 'small-order R' cases use R = the key point, and the ported test-webcrypto-sign-verify-eddsa.js:25 vector uses an order-8 R. If the !isSmallOrderEd25519Point(publicKey.data) clause is deleted, the R clause still returns false for all of them and the suite stays green. But with that clause gone a verifier accepts a forgery: under public key A = identity, signature R = encoding of the base point 58 66..66, S = 1 satisfies [1]B = R + [h]A for every message, and ED25519_verify at ncrypto.cpp:3710 returns 1. R = B is not in kEd25519SmallOrderPoints, so only the public-key clause rejects it. On the base branch this forgery is accepted; after merging it is rejected, but no test proves the clause that rejects it, contrary to the repository's own rule that deleting each load-bearing clause of a fix must break at least one test.

Verification: src/jsc/bindings/ncrypto.cpp:3717 return !isSmallOrderEd25519Point(signature.data) && !isSmallOrderEd25519Point(publicKey.data); has two independent clauses, and the publicKey clause is independently load-bearing. Every new test pairs a small-order key with a small-order R, so the R clause alone turns each one false. Deleting the publicKey clause therefore leaves every assertion green.

🟡 nit (optional): the "digest is still rejected" assertion is a bare toThrow(), so it does not pin the error the PR says it pins. At test/js/node/crypto/crypto.key-objects.test.ts:1909 any throw passes, including a TypeError from a wrong argument. Fix: assert the specific error, e.g. toThrow(expect.objectContaining({ code: "ERR_OSSL_EVP_COMMAND_NOT_SUPPORTED" })) or the exact message, so the new early-return in SignJobCtx::runTask cannot silently change the error class or code for the digest path. [also at: test/js/node/crypto/crypto.key-objects.test.ts:1910 - nit: the "digest is still rejected" assertion uses a bare toThrow(), so any throw at all (a TypeError from a bad argument, a different OpenSSL error) satisfies it.]

Why this was flagged

The test at test/js/node/crypto/crypto.key-objects.test.ts:1909 calls expect(() => verify("sha256", message, publicKey, signature)).toThrow() with no argument. The PR description states this test pins ERR_OSSL_EVP_COMMAND_NOT_SUPPORTED, but a bare toThrow() accepts any exception. The new branch at src/jsc/bindings/node/crypto/CryptoSignJob.cpp:108 is guarded by !m_digest; if that guard were dropped or the digest path's error changed to a different code or a generic Error, this assertion would still pass. The repository review instructions explicitly reject bare toThrow() and require a specific error class/code/message. On the base branch there is no such test, so this is a weakness in the new coverage rather than a runtime regression.

Verification: nit. Whenever the digest-path error for an Ed25519 crypto.verify("sha256", ...) changes class or code, this assertion still passes. test/js/node/crypto/crypto.key-objects.test.ts:1910 reads expect(() => verify("sha256", message, publicKey, signature)).toThrow(); with no argument, so any exception satisfies it. Consequence is weakened regression coverage of the digest path.

expect(() => verify("sha256", message, publicKey, signature)).toThrow();
});
});

Keep the vendored Node test unchanged.

test/js/node/test/parallel/test-webcrypto-sign-verify-eddsa.js is part of the Node.js vendored test tree. The new Ed25519 coverage is already covered by test/js/web/crypto/web-crypto.test.ts, which checks all listed small-order points and small-order R values. Remove this added block from the vendored file. Add separate Ed448 coverage to a Bun-owned test only if required.

The separate BoringSSL concern does not apply to Bun. process.features.openssl_is_boringssl is defined as true, so the Ed448 vector is not added.

Remove the added `smallOrderVerifyVectors` definition, the conditional Ed448
vector, the `testSmallOrderVerify` helper, and its invocation from the vendored
test. Keep any existing test code unchanged; add Ed448 coverage to a Bun-owned
test only if needed.
