Agent Reachability Matrix
Will personal agents reach you and buy?
Existing ARC evidence shows discovery rails, checkout paths, and known block risks. A detected rail is not a promise that a named agent can use it.

Rail / discovery evidence checked 2026-10-08 03:11 UTC. Index cart evidence uses the published scan below.
Measured means an ARC HTTP rail check or an Index browser cart test, not a live Muse, Instinct, ChatGPT, Gemini, Grok, or OpenClaw session. Checkout handoff is not a completed purchase. ARC is independent and not affiliated with Meta, Sierra, Shopify, OpenAI, or Google. PAP support is not confirmed.
Can agents check out?
Real HTTP agent-catalog check. Does not change the Index score.
Agents can reach checkout through Shopify's agent catalog.

https://countrylifevitamins.com/Personal Agent Protocol
PAP (announced Oct 2026 by Meta and Sierra with industry partners) is an open standard for how personal agents discover and work with businesses — website discovery, OAuth session, then site / APIs (MCP, OpenAPI) / company agent. ARC already answers the two-lane question: can agents discover you, and can they buy from you. Until the v0.1 spec ships, we probe sensible discovery candidates and label unknown clearly. ARC is not affiliated with Meta or Sierra.
Watching for PAP v0.1
No PAP-specific discovery markers detected yet. Spec v0.1 is not published; ARC is watching, not inventing support.

Not a claim of PAP support. Spec v0.1 is expected later this month; reference implementation coming. Related surfaces below (UCP, WebMCP, MCP well-known) are existing agent-discovery checks — not PAP.

What Grok tells shoppers is a real model call via API, checked against the store's pages, not the consumer Grok app. Whether agents reach checkout is two lanes: a real HTTP check of the store's agent catalog, and five ARC browser cart tests. Those attempts are not a live Muse, Instinct, Grok Bot, OpenAI dots, or OpenClaw session. The score is the browser lane. The catalog check does not change it.
