Fabric™

The governed foundation that makes agents trustworthy. A managed data estate, a permission-aware knowledge fabric over vector and graph retrieval, and the AgentOps machinery to evaluate and observe what agents do — so answers are grounded, cited and auditable rather than merely fluent.

FABRIC // GROUNDING LAYER

// Problem

The Problem

Most enterprise AI failures are not model failures. They are grounding failures: the agent answered confidently from the wrong document, or from a document the user was never entitled to see. Pilots pass because someone curated the corpus by hand; production breaks because nobody can curate at enterprise scale. Without lineage, nobody can explain where an answer came from — which means it cannot be defended, which means it cannot be used for anything that matters.

  • Retrieval that ignores permissions turns every agent into a data-leak surface.
  • Ungrounded answers are indistinguishable from grounded ones at the point of reading.
  • No lineage means no defensible explanation of how a decision was reached.
  • Agent behaviour drifts silently without evaluation harnesses and observability.

// Overview

Fabric is the substrate the rest of the platform stands on. It maintains the managed data estate with lineage and cataloguing, and layers a permission-aware knowledge fabric over hybrid retrieval — vector for semantic reach, graph for relationship traversal — so an agent's context is bounded by the requesting user's actual entitlements rather than by the corpus it was indexed against. Above that sits the AgentOps layer: evaluation suites, tracing, and guardian agents that police outputs against policy. Answers carry citations back to source by default.

// AI System

Why AI

The insight is that trustworthiness is an infrastructure property, not a prompt property. You cannot instruct a model into being auditable. Permission-aware retrieval enforces entitlement at the point of context assembly, before the model sees anything; graph traversal supplies the relational context that pure vector search misses; citation is a structural requirement of the retrieval contract rather than a request in a system prompt. This is what takes an agent from demo to production in weeks instead of quarters.

// Features

Features

  1. 01Entitlements enforced at context assembly, before the model receives anything.
  2. 02Hybrid vector and graph retrieval, so relational context is not lost to pure semantic search.
  3. 03Citation to source as a structural property of the retrieval contract, not a prompt instruction.
  4. 04Full lineage from answer back through retrieval to originating system.
  5. 05Guardian agents policing outputs against policy before they reach a user.
  6. 06Evaluation suites and tracing to detect behavioural drift before users do.

Observability

Every model call traced; evals run on real cases, not anecdotes.

Governance

Entitlements enforced at retrieval; rules versioned by the organisation.

Write-back

Systems of record are written only through the approval gate.

Evaluation and tracing observe every stage; drift is detected against suites, not anecdotes.
