## Check details

### PASS — llms.txt is served and agent-actionable (`llms-txt`)

markdown with an H1 and substantive content

### PASS — /.well-known/agents.json capability card parses (`agents-json`)

valid JSON; name="api.qa", 4 http endpoint(s) declared

### PASS — /icp.json self-classification surface (`icp-json`)

valid JSON with agent_classes — an agent can self-classify

### PASS — root content-negotiates (curl → markdown, browser → HTML) (`content-negotiation`)

Accept: */* got non-HTML text; Accept: text/html got HTML

### skip — API home answers machine-legible (JSON/markdown) to every client, browsers included (`machine-legible-home`)

no probe manifest declared — target does not claim the agent-first API contract; page surfaces may serve HTML

### PASS — machine-readable API contract (OpenAPI) is published (`openapi`)

OpenAPI parses; 4 path(s), 2 keyless GET candidate(s)

### PASS — MCP interface declared with transport + tools (`mcp-declared`)

mcp: stdio with tools [verify_domain, discover_domain, verify_pinned_spec] (presence-grade; stdio not spawned)

### skip — MCP endpoint publishes RFC 9728 protected-resource metadata (`mcp-oauth-protected-resource`)

MCP declared stdio transport (no url) — not an OAuth resource server; skipped

### skip — authorization server publishes RFC 8414 metadata (openid-configuration fallback) (`mcp-oauth-as-metadata`)

MCP declared stdio transport (no url) — not an OAuth resource server; skipped

### skip — authorization server advertises PKCE S256 (RFC 7636) (`mcp-pkce`)

MCP declared stdio transport (no url) — not an OAuth resource server; skipped

### skip — authorization server supports Dynamic Client Registration (RFC 7591) (`mcp-oauth-dcr`)

MCP declared stdio transport (no url) — not an OAuth resource server; skipped

### skip — protected-resource declares an RFC 8707 audience bound to the MCP origin (`mcp-oauth-resource-indicators`)

MCP declared stdio transport (no url) — not an OAuth resource server; skipped

### skip — unauthenticated MCP request returns 401 with WWW-Authenticate → protected-resource metadata (`mcp-www-authenticate`)

MCP declared stdio transport (no url) — not an OAuth resource server; skipped

### skip — AAP discovery advertises Ed25519 + approval methods + register/status/revoke + jwks_uri (`aap-discovery`)

no /.well-known/agent-configuration document (2xx) — target does not claim the Agent Auth Protocol

### skip — auth.md agent-identity advertised (agent_auth identity/claim/events + ID-JAG + SET revocation) (`authmd-agent-identity`)

no authorization-server metadata resolved (no MCP/OAuth AS declared) — nothing advertises an agent_auth block

### PASS — at least one declared endpoint answers 2xx with no key (`keyless-flow`)

3/3 sampled endpoint(s) answered 2xx keyless (seed 2033118251)

### PASS — payment boundaries answer as structured 402 offers (`offers-402`)

declared boundary answered HTTP 402 with a typed OFFER (type:"OFFER" + id/title + price|checkoutUrl|alternatives)

### PASS — surfaces cross-reference each other (linkset) (`linkset`)

Link header present on root

### PASS — attestation/identity ladder is declared (`attestation`)

attestation ladder declared (agents.json attestationLadder / icp.json ladder)

### PASS — sampled responses conform to their published schemas (`schema-conformance`)

2 sampled response(s) conform to their OpenAPI schemas

### PASS — claimed endpoints actually exist (no ghost surface) (`claims-honesty`)

every probed claimed endpoint exists (no 404/5xx)

### PASS — live responses match the published OpenAPI contract (full diff) (`contract-diff`)

live surface conforms to every declared contract; 5 additive deviation(s) (undeclared field/endpoint — live has more than declared, non-breaking)

### skip — card-declared probe manifest is valid (`probe-manifest`)

no probe manifest declared (agents.json top-level `probes`) — nothing to validate

### skip — capability card names its interfaces and cross-links its sibling surfaces (`card-interfaces-linked`)

no probe manifest — target does not claim the agent-first API contract

The full evidence bundle is embedded in the JSON report. Judging is a pure
function of the bundle — re-run the checks over it and you MUST get this
same grade, or the report is forged / the verifier version changed:
