generated: '2026-09-19' method: probed source: >- Live GET probes of the named /.well-known/* path list on www.remerrill.com and remerrill.com, 2026-09-19, plus the two documents the provider's own llms.txt and agent card name under /.well-known/ (agent-card.json and jwks.json). Every row below is a request that was actually issued; every status is the one returned. summary: hosts_probed: 2 paths_probed: 42 documents_served: 2 hit_count: 2 path_echo_control: passed note: >- R.E. Merrill serves exactly two well-known documents, both part of its A2A surface: the signed agent card at /.well-known/agent-card.json (saved and graded under a2a/) and the JWKS its signature header points at (/.well-known/jwks.json, one ES256 P-256 key, saved here verbatim). Every other named path returns the Next.js site's real HTTP 404 page (status 404, text/html, "404: This page could not be found") — a genuine 404 status, not a soft-200 shell — and a negative-control path that cannot exist also 404s, so the two 200s are served documents. No security.txt, no OAuth/OIDC discovery, no RFC 9727 API catalog, no APIs.json, no AAuth resource document, no ai-plugin, no UCP/ACP manifest. The apex remerrill.com 308-redirects every path to www and serves nothing of its own. There is no MCP server, so there is no separate MCP host to probe for RFC 9728 protected-resource metadata; the A2A resource host is www itself (row below, 404). The WellKnown pointer is emitted on the strength of the two served documents; no SecurityTxt pointer is emitted. hosts: - host: www.remerrill.com role: Website, REST API host (POST /api/line-finder) and A2A JSON-RPC host (POST /api/a2a) — one Vercel origin documents: - path: /.well-known/agent-card.json status: 200 content_type: application/json; charset=utf-8 bytes: 6129 file: ../a2a/remerrill-com-agent-card.json standard: A2A Agent Card (v1.0 supportedInterfaces shape; JWS-signed) note: Saved verbatim under a2a/ and graded in a2a/remerrill-com-a2a.yml (flavored — no top-level protocolVersion). - path: /.well-known/jwks.json status: 200 content_type: application/json; charset=utf-8 bytes: 268 file: remerrill-com-jwks.json standard: RFC 7517 JSON Web Key Set note: Named by the agent card's JWS protected header (jku).
