## Rulings

- 2026-09-20 — A2A Cosmetics is a2a-peptides.ai remade as is — same surface, door, issuer, payments door and agents app — for cosmetics: 18 markets, 13 rule sets, twenty tools, twelve reason codes.
- 2026-09-20 — Business to business: brands, manufacturers, retailers, distributors and their agents. The consumer is never the counterparty.
- 2026-09-20 — The taxonomy of record is the GSC SPARKS Beauty and Personal Care Taxonomy: four levels, then variant or form, then SKU / GTIN; segments and claims are attributes, never branches.
- 2026-09-20 — The showcase standard: every URL is read live at load; dead, wrong or parked goes to the pond with its reason; only validated rows are served; every field carries its source; counts are read from the validated set.
