agent-shoppable-census

A census probe that analyzes 100 of the largest US online sellers of engagement rings and diamond jewelry for agent-readiness. Fetches public URLs, records evidence, and classifies sellers into Tier A (merchant-built), Tier B (platform-inherited), or Unreachable based on MCP Registry entries, custom MCP endpoints, agents.md/llms.txt files, ACP checkout endpoints, and UCP profiles.
