TypeSafe Jev playbook (unofficial)

This playbook is jev.pro’s operate pillar: checklists you can run in a review, not a story-shaped “how to build with System One” essay. TypeSafe’s official narrative remains how to build. We are independent and unofficial. We do not issue API keys.

Path

Stage Page Exit gate
Design Design checklist Action space + atomic questions written
Implement Implementation checklist Pinned model, traces, error map
Launch Launch checklist Harness + fail-closed + labeled claims
Compose Intent routing, guardrails, RAG filter Code owns side effects
Compare vs classifiers, vs agents You know when not to use Jev

Operate loop (weekly)

  1. Re-fetch the channel matrix (model ids, promos, 32k vs 64k cards).
  2. Diff response.model in logs — catch silent alias moves if someone shipped jev-latest.
  3. Sample handoff traces; add misses to the gold file.
  4. Re-read TypeSafe jaggedness if you changed criteria.

Production gates we will not skip (SEO-GEO)

What this playbook is not

Not official TypeSafe. Not a paid “Pro” tier. “Pro” here means production craft (see NARRATIVE.md in the repo).

Hub: Open. Official: docs.typesafe.ai.
