4 SQLite Tables Replaced My $200/mo AI Observability Stack

My AI agent system runs 16 teams across 4 different LLM providers. Two months ago, one team silently started hallucinating policy decisions. I caught it in 11 minutes. With 47 lines of Python writing to a SQLite database. OpenTelemetry is now working on semantic conventions for LLM tracing. That's great. But I needed this six months ago, so I built my own. Here's the full setup. TL;DR: A SQLite-backed audit trail for multi-agent AI orchestration logs every LLM call, model routing decision, and bias detection event.
