Together these layers form a self-repairing harness where each production failure automatically becomes a regression test, making the system progressively harder to break. The stack supports LangGraph, CrewAI, and 50+ frameworks and can be self-hosted in three commands. ## Full article daily.dev links to this article rather than hosting it.
