Machine-readable surfaces (index)

Machine surfaces

• /node.json

  Root-path machine surface per Phase-0 D-03. NEVER /api/node.json.

  Kind: json · Content-type: application/json; charset=utf-8 · Index policy: index-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /ai-context.jsonld

  JSON-LD context including the byte-exact definition and NODE-21 role claim.

  Kind: jsonld · Content-type: application/ld+json; charset=utf-8 · Index policy: index-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /llms.txt

  Plain-text LLM-friendly summary with the byte-exact definition and canonical links.

  Kind: text · Content-type: text/plain; charset=utf-8 · Index policy: index-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /sitemap.xml

  XML sitemap (sitemaps.org 0.9) listing all indexable HTML routes for search-engine discovery (Google Search Console, Bing).

  Kind: xml · Content-type: application/xml; charset=utf-8 · Index policy: index-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /api/truth-loops.json

  Additive federation surface. One publication-authority loop per canonical work NODE-21 cites (Papers 3-5, Web4 node state draft, and the 3 September 2026 technical notes). No inter-node HTTP at runtime; loops derive from GRAPH_EDGES + IDENTITY only.

  Kind: json · Content-type: application/json; charset=utf-8 · Index policy: noindex-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /api/citations.json

  Additive federation surface. Every federation-canonical work cited by NODE-21 with its author (Q137953077), publisher (Q138189229), ORCID identity anchor, canonical identifier (DOI or IETF Datatracker), and NODE-6 evidence deep link. Emits CreativeWork / Article references only — no self-authored ClaimReview.

  Kind: json · Content-type: application/json; charset=utf-8 · Index policy: noindex-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /api/evidence-manifest.json

  Additive federation surface. Every NODE-6 evidence anchor bound to this node. Only HEAD-verified /claimreviews/{slug}/evidence.md URLs are published as resolved anchors; unresolved slugs are declared under pending_records with evidence_status.

  Kind: json · Content-type: application/json; charset=utf-8 · Index policy: noindex-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /api/topology.json

  Additive federation surface. Node-scoped topology view. Explicitly NOT the canonical authority — that lives on NODE-1. Exposes federation_graph_edges and machine_endpoints for AI discovery.

  Kind: json · Content-type: application/json; charset=utf-8 · Index policy: noindex-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /api/mcp.json

  Additive federation surface. Read-only capability disclosure. IDENTITY.mcp_status = 'not-operated' — no MCP server, no JSON-RPC, no transport, no tools, no prompts. Same shape NODE-20 uses to declare its /.well-known/mcp.json.

  Kind: json · Content-type: application/json; charset=utf-8 · Index policy: noindex-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /.well-known/mcp.json

  Additive federation surface. Same read-only capability disclosure as /api/mcp.json, served at the RFC 8615 well-known path so generic discovery tooling finds it.

  Kind: json · Content-type: application/json; charset=utf-8 · Index policy: noindex-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.

• /api/briefing.jsonld

  Additive federation surface. Structured briefing: capabilities referenced from the 4 canonical publications, evidence anchors, cited publications. Every capability claim resolves to a paper via GRAPH_EDGES publication_metadata (§7.4).

  Kind: jsonld · Content-type: application/ld+json; charset=utf-8 · Index policy: noindex-follow

  Phase 4: contract-only stub. Real payload is minted in Phase 5.
