Research direction

Start at jwt.verify and trace how the supplied publickey reaches Node.js Verify.verify in internal/crypto/sig.js. The reproduction uses placeholder token and key values, so first obtain complete inputs and reproduce with the reported Node.js 14.16.0 environment; done requires a confirmed project-side cause and a regression test or documented resolution.
