The architecture keeps raw private data local-only, uses redaction before any public export, and enforces mandatory human review gates before merging. The result is an AI coding assistant that starts from the developer's own review preferences, Rails patterns, and shipping standards rather than generic defaults. The post also serves as a services pitch for CTO AI transformation work. ## Full article daily.dev links to this article rather than hosting it.
