Post-Sprint Update: Resilient Client Factories and Bulletproof Evaluation Baselines
We have just pushed a major architectural enhancement to the enterprise-grade-sprints branch to solidify the production resilience and evaluation safety of Sentry Governor.
What is New in this Enhancements Cycle:
Production-Safe Demo Isolation (run_local_demo.py)
- Instead of introducing dangerous, fail-open environment conditionals inside our core auth.py router (which risks accidental backdoor exposure in cloud deployments), we implemented a blessed, isolated testing pattern using FastAPI's dependency injection mechanisms (app.dependency_overrides).
- Running python run_local_demo.py safely mocks authentication only within that local process scope, keeping our production infrastructure byte-for-byte unchanged and secure.
Relaxed Input Validation and Schema Intelligence (schemas.py)
- Refactored the /contracts POST payload schema to inject robust default configurations (fivetran_production domains and catch-all * tables).
- This guarantees backward-compatibility for minimal webhook simulators while preventing common 422 Unprocessable Entity validation friction during automated data ingestion cycles.
Cooperative Cascade Fallback Architecture
- Hardened the system's runtime dispatch mechanism. If the primary Model Context Protocol (MCP) server or managed Agent Engine becomes unavailable, the system gracefully degrades to a generic Vertex AI loop, and finally to a rule-based deterministic parser. The ingestion loop never crashes.
Dynamic Risk Calculations Verified
- Confirmed exact compliance weights mapped against EDPB Article 83 parameters—ensuring high-risk vulnerabilities (like unmasked payment cards) dynamically price out a defensible 4.2-Million-Euro Financial Exposure Blast Radius backed entirely by automated database metadata hooks.
