Jev Engineering

The full course on putting a decision layer between your LLM and your code. One payment, yours for good.

• Ten steps that build one working gate, from the first split to production rollout
• Runnable Python in every chapter, targeting Python 3.12 and up
• The complete merge gate: state builder, questions, thresholds and rule ordering
• The parallel battery and dynamic menu patterns for agents that run every turn
• Shadow mode, calibration curves and versioning so you can automate safely
• The harness: deny rules, limits, outcome verification and a resumable journal
• Where Jev does not belong, and when an if statement beats any model
• Honest numbers: vendor claims labelled as vendor claims, arithmetic you can check
