Procurement human handoff 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 human handoff slice of the procurement path decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to procurement path decisions human handoff. Primary search language: Procurement Jev human handoff. 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
Handoff is a first-class outcome for procurement path decisions, not a failure of Jev. When the intake orchestrator cannot auto-act, a human sees a packed purchase justification — not a chat transcript. We do not ask Jev to write the reviewer essay.
Hub: Use cases. Compare, when the other tool is the real job: procurement workflows.
Human Handoff inputs
Humans should see what the model saw (filtered), not the warehouse dump you correctly refused to POST:
{
"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
| Signal | Typical reason enum (you name it) |
|---|---|
| path other / low confidence | buyer_review |
| sole_source + low policy_ok | need_justification |
| amount ≥ bid floor | force_bid |
| ethics language | compliance |
These are application outcomes next to HTTP 200, not invented TypeSafe status codes.
Send the reviewer:
- req.id + filtered justification
- policy version + amount
- answers + probabilities
- Path already forced by code
- Confirmation no PO was cut
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
Do not page humans on a single Score unless your conjunction says so. Pair with confidence thresholds. 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
Write the gold label back into the offline set. That is how floors move. 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
Is handoff a Jev failure? No. It is a first-class outcome. Abstention is “no auto action”; handoff is the queue you send that case to (glossary).
Should Jev draft the reviewer note? No. Send structured answers. Generation is the wrong job.
Where is the rest of the Procurement pack? Start with Procurement confidence thresholds and Procurement audit trail. 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.
