Procurement production rollout with Jev

Requesters write “need this vendor, they already know us.” Catalog, bid thresholds, and vendor master still own the buy. Jev scores policy-fit of the justification you paste. It does not raise POs or pick winners.

This unofficial page is the production rollout slice of the procurement path decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to procurement path decisions production rollout. Primary search language: Procurement 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): Catalog vs bid vs exception as typed questions + policy excerpts — not a clone of a procurement-workflow SaaS sitemap.

Procurement use-case context

Production rollout for procurement path decisions 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 (creating a purchase order or awarding a vendor).

Hub: Use cases. Compare, when the other tool is the real job: procurement workflows.

Production Rollout inputs

Ship the contracted payload, the pinned id, and a documented safe default when the API is unavailable:

{
  "req": { "id": "pr-77", "text": "Only Acme can integrate with our badge system by Friday." },
  "policy": { "sole_source": "Sole-source needs a named alternative and a date risk, not brand preference." },
  "bands": { "amount_band": "25-50k", "category": "security_hardware" }
}

Decision signals and actions

Keep the workflow code you already designed:

def proc_route(ans, amount_cents):
    path = ans["path"]
    if path.confidence < FLOOR or path.choice == "other":
        return "buyer_review"
    if amount_cents >= BID_FLOOR:  # code
        return "force_bid"
    if path.choice == "sole_source" and ans["policy_ok"].noul < T_OK:
        return "need_better_justification"
    return f"path:{path.choice}"

Do not treat a Noul of 0.5 as a “medium” procurement path decisions 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 create a PO or award a vendor. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For procurement path decisions, treat auto_create_po as the high bar (creating a purchase order or awarding a vendor). 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 creating a purchase order or awarding a vendor. Do not guess.

Where is the rest of the Procurement pack? Start with Procurement evaluation and Procurement confidence thresholds. Cluster hub: Use cases.

Will Jev pick the cheapest vendor? No. Price compare in code or the bid tool. Jev judges the justification text.

Can we paste three PDF quotes? Not as images. Extract facts you need; keep state small. Unused tokens still bill (vendor claim — confirm models page).

What this page does not claim

• Not a procurement suite or savings calculator.
• Not competition-law advice.
• Not official TypeSafe.
• Official TypeSafe status, or that jev.pro issues API keys.
• That a schema-constrained answer is automatically factually correct.
