HR production rollout with Jev
Inbound applications and tickets mix eligibility, policy questions, and messy free text. The ATS, payroll, and your employment counsel still own outcomes. Jev can score job-related criteria you wrote. It is not an ATS and must not become a proxy for protected-class decisions.
This unofficial page is the production rollout slice of the HR screening operations pack. Intent: apply the Jev (TypeSafe System One) decision model to HR screening operations production rollout. Primary search language: HR Jev production rollout. Confirm patterns on docs.typesafe.ai. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.
Independent angle (cover ≠ clone): Job-criteria Nouls with an explicit do-not-encode-protected-class lint — not a clone of an ATS or HR-screening product page.
HR use-case context
Production rollout for HR screening operations is Operate-pillar work: pin, shadow, canary, abort. It is not a launch-checklist clone of a rival “build with System One” guide — we only talk about this pack’s blast radius (auto-rejecting a candidate or taking employment action).
Hub: Use cases. Compare, when the other tool is the real job: HR screening.
Production Rollout inputs
Ship the contracted payload, the pinned id, and a documented safe default when the API is unavailable:
{
"app": { "id": "c-190", "text": "5 years Python; no work auth mentioned; relocating July." },
"role": { "must": "Python in production; authorized to work without sponsorship this cycle." },
"ticket": { "type": "inbound_app" }
}Decision signals and actions
| Stage | What changes | HR rule |
|---|---|---|
| Shadow | Nothing customer-visible | ATS stage unchanged; log Jev screen only. |
| Canary | One low-blast slice auto-acts | Auto hold_docs only; every reject stays human. |
| Abort | Auto-act off | Role must-haves edit or complaint → freeze writes. |
Keep the workflow code you already designed:
def hr_screen(ans):
s = ans["screen"]
if s.confidence < FLOOR or s.choice == "other":
return "recruiter_review"
if ans["work_auth_clear"].noul < T_AUTH:
return "hold_docs"
if s.choice == "reject_role_mismatch" and ans["must_have_fit"].score <= 1:
return "recruiter_confirm" # adverse action stays human
return s.choiceDo not treat a Noul of 0.5 as a “medium” HR screening operations score — it means yes and no are equally likely. Conjunctions stay in your code.
Guardrails and escalation
Safe default if System One errors or confidence is low: do not auto-reject or take employment action. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For HR screening operations, treat auto_reject as the high bar (auto-rejecting a candidate or taking employment action). Tune on labels — see offline evaluation.
Evaluation and rollout notes
Promotion gate = evaluation green on the pinned id + audit traces for the canary. Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.
Official Python and JavaScript SDKs read TYPESAFE_API_KEY and retry documented 429/529. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.

FAQ
Can I ship on jev-latest?
Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. Shadow first.
What is the safe default if System One is down? Fail closed on auto-rejecting a candidate or taking employment action. Do not guess.
Where is the rest of the HR pack? Start with HR evaluation and HR confidence thresholds. Cluster hub: Use cases.
Is this an ATS or hiring decision system of record? No. It is an unofficial typed-screening pattern. Employment law stays with you and counsel.
Can we score “culture fit”? We recommend you do not. Keep criteria job-related and lint for proxies.
What this page does not claim
- Not an ATS, not employment-law advice, not a fairness certificate.
- No quality-of-hire numbers.
- Not official TypeSafe.
- Official TypeSafe status, or that jev.pro issues API keys.
- That a schema-constrained answer is automatically factually correct.
