Riskratchet and PreFlight launch linting tools to prevent AI-generated code degradation

According to GitHub and tool documentation, Riskratchet provides a maintainability ratchet for Python code that tracks quality metrics that can only move down, while PreFlight is a local AST daemon and VS Code extension that blocks hallucinated code and schema drift in real-time. Both tools address technical debt accumulation from AI-assisted code generation.
