Jev in Production
Twelve modules. Modules 0 and 1 are free.
- 0Start hereWhat Jev is in one table, the three primitives, and your first call in curl, TypeScript and Python.
- 1Where Jev belongs in your productThe three architectures, the rule that code keeps control, and twelve places where a typed decision pays for itself.
- 2Question designAtomic questions, contrastive criteria, escape options, backtick paths, and how to choose between Choice, Score and Noul.
- 3Confidence and thresholdsProbabilities, confidence, the three bands, thresholds that scale with risk, and a shadow evaluation you can run tonight.
- 4The nine jagged edgesLiteral reading, numbers, dates, indirection, large state, adversarial text, contradictions, invariants, generation. One real trigger each, and the fix in code.
- 5Playbook: leads and formsRoute every inbound message with one request: intent, ICP fit, urgency, budget, company size. Composite score, weights you own, a corpus to prove it.
- 6Playbook: support and guardrailsTriage a ticket with speculative fan-out, then screen every LLM input and output with a hazard battery and a route() you can read.
- 7Playbook: agent gatesA tool-call gate for coding agents, a browser agent that picks one click per step, a pre-commit hook, code review by risk, and function calling from a sentence.
- 8Playbook: search, SEO and RAGRerank a shortlist with one Noul per candidate, keep only RAG passages that earn their place, check citations, grade pages for search intent, and walk a taxonomy.
- 9ProductionCost math, latency budgets, batching, retries, caching, logging distributions, versioning the catalog, and a CI test that fails when a question drifts.
- 10Final projectA decision layer on your own product in five steps, with the corpus template, the review checklist, and what to write down before you ship.
- BBonus: voice to decisionThe Design live case. A spoken sentence becomes a typed edit on a web page in one Jev request of 27 questions, 300 to 750 ms, measured on 508 real sentences.
