> Results: we are cross-compatible on X-Wing, but not on P256 (and that's after hacking my script to use the CFRG label not the LAMPS label, so there's clearly some other bug at play, but I have no idea what, so of course I assume it's on the cfrg reference impl side 😋).

Could be https://github.com/cfrg/draft-irtf-cfrg-concrete-hybrid-kems/pull/21.
