Illustrative architecture: GraphRAG and context engineering

GraphRAG Enterprise Knowledge Intelligence

A permission-aware retrieval system combines graph traversal, semantic search, and structured lookup. Bounded context assembly returns grounded answers with citations and source provenance.

Architecture summary

GraphRAG Enterprise Knowledge Intelligence system boundary

Source connectors feed parsing and entity and relationship extraction. Knowledge graph, vector index, and structured index support hybrid retrieval before tenant and ACL filtering, context assembly, and cited generation.

End-to-end workflow

GraphRAG Enterprise Knowledge Intelligence execution path

A user question becomes a retrieval plan, graph traversal and semantic and structured searches run together, permission filters remove inaccessible results, hybrid ranking selects evidence, and the agent answers with provenance.

Context and data flow

GraphRAG Enterprise Knowledge Intelligence context movement

Context includes bounded passages, graph relationships, structured facts, source identifiers, freshness metadata, and permission decisions. Citations point back to the selected source records.

Agent responsibilities and boundaries

GraphRAG Enterprise Knowledge Intelligence ownership limits

The agent cannot retrieve around ACL filters, invent source permissions, alter indexes, or treat unsupported output as evidence. Restricted-source access can require review.

Deterministic controls

GraphRAG Enterprise Knowledge Intelligence enforced controls

Connector schedules, parsing rules, entity schemas, ACL enforcement, tenant filters, ranking limits, context budgets, citation formatting, and freshness checks are deterministic.

Security and permissions

GraphRAG Enterprise Knowledge Intelligence trust boundaries

Permission filters run before retrieval results reach the agent. Tenant isolation, source-level access, retention rules, provenance, and restricted ingestion credentials protect enterprise knowledge.

Scaling and reliability

GraphRAG Enterprise Knowledge Intelligence operating model

Incremental ingestion, change detection, partitioned indexes, asynchronous graph enrichment, cached plans, bounded traversal, and context limits manage freshness and cost.

Failure modes and recovery

GraphRAG Enterprise Knowledge Intelligence recovery paths

Failed connectors retain the last known freshness state, malformed documents enter a review queue, partial indexes do not replace valid versions, and missing evidence produces a bounded response instead of fabricated support.

Software testing

GraphRAG Enterprise Knowledge Intelligence deterministic test coverage

Tests cover parser outputs, entity and relation extraction, ACL enforcement, tenant separation, graph paths, vector retrieval, structured filters, citations, and freshness updates.

AI evaluation

GraphRAG Enterprise Knowledge Intelligence behavior evaluation

Retrieval evaluation measures relevance, relationship coverage, hybrid ranking, permission correctness, context sufficiency, citation accuracy, and grounded answer quality.

Observability and AgentOps

GraphRAG Enterprise Knowledge Intelligence operational evidence

Operators inspect connector health, ingestion lag, index versions, retrieval plans, filter decisions, selected evidence, citation paths, and evaluation regressions.

Deployment model

GraphRAG Enterprise Knowledge Intelligence deployment boundaries

Connectors, parsers, extraction workers, graph and vector stores, retrieval services, and answer runtime deploy with separated ingestion and query credentials.

Engineering tradeoffs

GraphRAG Enterprise Knowledge Intelligence deliberate constraints

Graph enrichment adds modeling and freshness work but exposes relationships vector similarity can miss. Bounded retrieval favors traceable evidence over maximum context volume.
