# AE24-028

The Radar Audit Engine achieves sub-60-second SLA through parallel fan-out architecture: Branch A (Playwright scraping), Branch B (Google PageSpeed API), Branch C (Qdrant RAG for industry benchmarks) run simultaneously. Results fan-in to Gemini Flash for scoring and analysis, then to HTML template generator. Redis caching prevents re-processing of recently audited sites.
