# elyssah.ai — a brand on the GSC Agentic Core

> GreenCore Solutions Corp. (GSC), Vancouver, built the GSC Agentic Core — the governed context AI agents act on for brands and retail: two billion datapoints on 78k brand records, 16k makers, 15k retail banners and 3.3m retail points of sale across 50 markets, served over the Model Context Protocol (MCP) from 18 Microsoft Azure regions. The Agentic Core powers two agentic commerce hubs — A2A-Cosmetics.ai (18 markets) and A2A-Peptides.ai (35 countries) — designed with, and read by, ChatGPT, Claude, Gemini, Copilot, Grok, Perplexity and Mistral, with 100m+ AI Agent transactions year to date.

> 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.

## The stack
GSC operates the jurisdiction and execution layers of its own stack: Standard-10060 sets the rules, ECO-10060 defines the object, SM-ECO-10060 resolves the jurisdiction, ACM-68000 carries the execution.
SM-ESG-CPG carries the ESG record (https://sm-esg-cpg.org). SM-AIO-CPG carries AI Orderability (AIO) (https://sm-aio-cpg.org).
Operated by GreenCore Solutions Corp.

## SM-ESG-CPG
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.
