Ruben FiszelandClaude Opus 4.8 f5713621c8 fix: accept any PEM wrapping for the guest key, keep the public-key check
The SPKI guard decoded the body with the strict RFC 7468 decoder, which enforces
64-column wrapping, so a legitimate public key wrapped otherwise (or a PKCS#1
`RSA PUBLIC KEY`) was refused where jsonwebtoken would have parsed it. Decode the
body leniently like jsonwebtoken, then require the DER to be a public-key
structure: an SPKI (RSA or EC) or a PKCS#1 RSA public key. Private material
satisfies neither, so the round-13 bypass stays closed. Test adds a one-line
(non-64-column) public key as a positive control.
