Spec → ReviewAttestation
What is ReviewAttestation? A portable, source-attributed review summary. UKLSP carries attestations about reviews, not review bodies — agents can weigh provenance.
Reviews live on many platforms; UKLSP doesn't republish them, it attests to them: source, rating, count, when sampled, and who sampled it. Agents get provenance-weighted signals instead of scrape-of-a-scrape numbers, and platform terms are respected because review bodies never enter the manifest.
