-TrustGraph is an agent runtime platform built around context graphs — structured, queryable representations of your domain knowledge that ground every agent query in verified, explainable facts in private deployments with sovereign control. The platform is the full stack for agentic systems: context graphs, memory, retrieval, orchestration, and inference for precision-critical agent workloads.

+- **Agent Console** — Query your agents directly with streaming responses and live explainability event tracking, so you can watch reasoning unfold in real time
+- **GraphRAG View** — Interactive graph RAG queries with a visual explainability DAG and inline provenance display, making it easy to see exactly where answers came from
+- **Context Explorer** — An interactive 3D context graph explorer with dynamic graph loading, BFS neighborhood extraction, edge pulse animation, and multiple navigation views
+- **Document Ingestion** — A complete upload and submission workflow with page and chunk inspection and document structure browsing
+- **Ontology Workbench** — A full ontology editor with class and property trees, OWL/XML and Turtle import/export with round-trip fidelity, circular dependency detection, and safe-delete confirmation dialogs
+- **Schema Workbench** — Interactive schema management with list, create, edit, and delete operations including field and index management
+- **Flow Management** — Flow creation and detail views with configurable parameters, temperature controls, and grouped storage layout
+- **Workspace UX** — Workspace selection and management surfaced directly in the interface
+- **Prompt Editor** — A dedicated prompt editing workflow
