Accessing the unofficial Jev documentation guide
jev.pro is the unofficial field guide. Canonical facts live at docs.typesafe.ai. Start at Explain, then Integrate.
Jev API keys
TypeSafe keys are bearer tokens from the console. This site never issues, sells, or proxies keys.
The TypeSafe Playground
The official Playground is the fastest way to paste state, mix primitives, and see typed answers before you write code.
Authentication concepts for Jev integrations
Jev auth is a bearer key or a documented gateway credential. 401 is not a retry. This site never issues keys.
Jev sandbox access and safe experiments
Sandbox Jev with fixture state, a pinned model, and no irreversible side effects. Official docs do not name a separate sandbox host.
Jev workspace setup checklist
Set up a Jev workspace: one door, env secret, pinned model, filtered state, and a replayable questions file.
Permissions and roles around Jev decisions
Jev does not replace your IAM. Roles live in your app; the model only fills typed slots your code is allowed to act on.
Onboarding a team to Jev System One
Onboard a team with one door, a shared questions module, review reason codes, and vendor-labeled claims — not a key from this site.
Promoting Jev decisions between environments
Promote Jev configs like code: pin the model, copy questions and floors, never promote jev-latest as if it were frozen.
Jev version pinning
Pin jev-1.13.0; log response.model. Unofficial — not a changelog clone. Confirm on docs.typesafe.ai.
