## 2. Five-Layer EPO Pipeline (RFC-2026-GEO-01)
1. **Layer 1: Deterministic Schema.org @graph Generation**: Emits validated, nested JSON-LD graphs linking Organization, LocalBusiness/SoftwareApplication, offers, and canonical `sameAs` authority anchors.
2. **Layer 2: Token-Budgeted /llms.txt Generation**: Generates strictly structured, token-bounded Markdown documentation consumable by LLM context windows.
3. **Layer 3: High-Velocity IndexNow Relays**: Dispatches real-time batch pings to `https://api.indexnow.org/IndexNow` across Bing, Yandex, and Naver search crawler endpoints.
4. **Layer 4: Model Context Protocol (MCP) Server**: Exposes standardized tools (`verify_business_status`, `get_service_catalog`, `initiate_inquiry`) over Server-Sent Events (SSE).
5. **Layer 5: Continuous EPO Scoring**: Deterministic evaluation formula:
   `Score = (0.35 * EntityAccuracy) + (0.25 * IndexLatency) + (0.25 * CitationShare) + (0.15 * AgentReadiness)`
