ARCE-Autonomous Remediation and Compliance Engine

ARCE (Autonomous Remediation & Compliance Engine) transforms how organizations handle supply chain vulnerabilities. Instead of alerting engineers and waiting days for manual patches, ARCE closes the entire loop autonomously. Powered by IBM Bob in a custom compliance-remediator mode, ARCE orchestrates two MCP servers to execute a 9-step pipeline: it scans dependencies with pip-audit, verifies exploitability through AST-based reachability analysis (ensuring the vulnerable function is actually called, not just imported), upgrades to the latest stable version, runs tests, and — when tests break due to API changes — self-corrects by reading the error and reasoning about the fix. After tests pass, Playwright verifies the running application works end-to-end. ARCE then generates a compliance-ready audit trail documenting every decision, attaches a CycloneDX SBOM, and opens a governed GitHub Pull Request with full evidence. The self-correction loop is the breakthrough: Bob doesn't blindly patch — it upgrades, discovers the upgrade broke tests, reads the TypeError, identifies the breaking API change, and applies the fix. This is agentic reasoning, not scripted automation. Key differentiators: AST reachability analysis eliminates false positives, severity-aware policy engine gates remediation decisions, real-time React dashboard shows live metrics (MTTR, CVSS delta, success rate), and the entire stack costs $0. ARCE reduces mean-time-to-remediate from days to under 4 minutes while producing governance artifacts that satisfy CISO and compliance requirements out of the box.
