AI Fraud Investigation Copilot

Agentic RAG system for evidence-grounded fraud reporting

A LangGraph-orchestrated investigation agent that grounds every finding in verifiable evidence, combining structured SQL retrieval with pgvector semantic search, enforcing citation validation to mitigate hallucinated claims, and running self-hosted inference via Ollama. Built on FastAPI, with retry logic and automated testing for reliable, structured LLM workflows.
