This is what we do today (related), I'd like to make sure this is correct.

I think you want records in Grype DB that mean, for example, https://osv.dev/vulnerability/CGA-46f4-r7mm-232v fixes CVE-2026-31988 and GHSA-gmq8-994r-jv83?
That's what the "isAdvisory" is checking for, because that's the semantics AlmaLinux advisories have, see for example https://osv.dev/vulnerability/ALSA-2026:4443 claims to fix 2 CVEs.
Generally for transformer changes we want to work backwards from the matching semantics we're trying to make Grype do.

As part of moving to OSV for Chainguard feed, this adds the transformer for it. There is another PR that I'll link in vunnel for it shortly and x-link them.
I think we need this: anchore/vunnel#1082 to land first
