Added operator and funding disclosures, provenance-bearing comparison facts, semantic ordered rankings, distinct retailer and evidence actions, a 48-hour offer-claim gate, llms.txt, OpenAPI documentation and IndexNow support. API v1 remains backward-compatible.
Expanded to seven category-specific groups of 20 exact UK products. Every category has its own method, ranks 1–20, source-linked images, offer receipts and attributable redirects.
Product pages, APIs and comparison tables now state that scores are meaningful only within a category. The shared platform contract covers identity, provenance, freshness, owner pools and commercial independence.
Exact identity, traceable inputs, complete scoring fields, a checked offer and resolved material conflicts remain hard gates. Missing independent testing now lowers evidence quality and must be disclosed instead of making the entire catalogue unusable.
