# elyssah — Skin First · the GSC stack behind a brand

> elyssah takes its name from Elysium — the place of renewal. A proto-agentic Skin First beauty brand, invented by GreenCore Solutions Corp. (GSC) for case study purposes.
>
> Skin has its own intelligence. It renews, defends, and corrects on its own cycle. elyssah exists to support that cycle, never to cover it. Every formula begins as treatment; color is what it wears on the way out the door.
>
> elyssah is agentic in its approach to Answer Engine Optimization (AEO) across ChatGPT, Gemini, Perplexity, Grok, Claude, Mistral, and Copilot.

elyssah is GSC's reference brand in the Contoso/Fabrikam tradition: the scenarios are invented, the infrastructure is real. GSC does not disclose its customers' data.
What follows is the GSC stack behind the brand — live, and graded in public. Operated by
GreenCore Solutions Corp.

## 02 · AI Agents for Retail AI ERP Procurement
An AI Agent is a small autonomous coded machine-to-machine software. In CPG procurement it
replaces tens of thousands of humans pushing emails and PDFs — one AI Agent, one SKU,
human-signed on every order. GSC's agents put a brand's SKUs in front of retail AI ERP
procurement systems in 50 nodes. Operated by GreenCore Solutions Corp.
- 11.5M AI Agent transactions a month on GSC's network · 4.2 every second
- 50 SM-ECO-10060 sovereign nodes · 100% of orders closed by a human

| Step | Surface | What the buyer's agent does |
| --- | --- | --- |
| Discover | /.well-known/agent-card.json · /.well-known/ai-catalog.json | reads the agent card and the ARD catalog on this host |
| Resolve | mcp.cpgknowledgegraph.ai/mcp | resolves the SKU on the CPG Knowledge Graph — GTIN-first, deterministic |
| Request | mcp.cpghumanintheloop.ai/mcp · submit_rfq · request_terms | lodges an RFQ against a gsc-demo: SKU URI and asks for terms |
| Track | check_rfq_status · escalate | follows the ticket on the same inbound |
| Sign | gsc-navigator.ai | waits — a human signs before any order executes |

The buyers in elyssah's traces are Verdemar Grocery and Northline Convenience — GSC's reference
retailers in the same Contoso/Fabrikam tradition. GSC does not disclose its customers' data.

## 03 · CPG Knowledge Graph — SPARKS, the source of truth
The CPG Knowledge Graph is where a brand becomes resolvable. elyssah is on it as
gsc-demo:brand/elyssah-ai with 10 SKUs, each classified under SPARKS, each a gsc-demo: URI.
The graph is operated by GreenCore Solutions Corp. and served live over MCP.
- 15,688 retail grocery banners · 3.29M points of sale · 50 global markets
- 38,350 BPC brands · 2B datapoints

## 04 · SPARKS — deterministic classification, 10 SKUs
SPARKS is the classification the CPG Knowledge Graph carries. Every SKU resolves to one class
and one subclass — no free text, no guessing. Every elyssah SKU is clinically tested,
compliant, and authorized for its channel. Operated by GreenCore Solutions Corp.

19 of them: home territory Italy, the European Union, the Americas, and three Asian
markets. Operated by GreenCore Solutions Corp.

## 06 · SM-ESG-CPG — the record layer
Every elyssah claim — clinically tested, compliant, authorized for its channel — names its author: the maker asserts, the certifier issues, the record carries both. SM-ESG-CPG makes those claims resolvable by agents across 50 sovereign nodes. The protocol carries no scores, ratings, or rankings — it returns the record as lodged, and the buying agent decides. Operated by GreenCore Solutions Corp.

## 07 · SM-AIO-CPG — AI Orderability
SM-AIO-CPG carries AI Orderability (AIO): the orderability record that tells a buying agent
whether a SKU can be ordered, by whom, through which channel, in each of the 50 nodes. It is
the record an elyssah AI Agent carries to market. The record layer answers procurement systems
and consumer shopping agents alike. Operated by GreenCore Solutions Corp.
