KYC confidence thresholds with Jev

Jumio-class vendors, sanctions lists, and liveness stay the system of record. Jev can ask whether the leftover narrative looks complete or internally inconsistent. It does not verify a passport and it is not a licensed KYC program.

This unofficial page is the confidence thresholds slice of the KYC residual-text decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to KYC residual-text decisions confidence thresholds. Primary search language: KYC Jev confidence thresholds. 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): Vendor attests identity; Jev only labels residual application text after structured checks. Fail closed — not a clone of KYC-vendor IA or an “AI KYC” product page. Treat floors as production gates and price the false-reject cost — official 0.5/0.9 sketches are illustrations.

KYC use-case context

Thresholds turn KYC residual-text decisions answers into act / review / abstain. They are product policy, not a hyperparameter TypeSafe ships. Official 0.5 / 0.9 sketches are illustrations. This slice also carries the false-reject discussion: over-gating KYC residual-text decisions hides calibration.

Hub: Use cases. Compare, when the other tool is the real job: KYC vendors.

Confidence Thresholds inputs

You need (1) pinned answers on a frozen contract and (2) labels for hold / proceed / escalate gold from KYC analysts, plus contradiction gold. State shape:

{
  "application": { "id": "APP-19", "narrative": "I live in Lisbon but the business is registered in Delaware for tax reasons." },
  "vendor": { "id_result": "pass", "sanctions_hit": false, "country_claimed": "PT" },
  "policy": { "consistency": "Flag country or occupancy claims that contradict vendor country_claimed." }
}

Decision signals and actions

FLOORS = {
    "park_for_ops": 0.55,      # illustrations — replace
    "auto_approve_account": 0.95,
}
NOUL_TAU = 0.80  # for narrative_consistent

def allow(ans, action):
    return ans.confidence >= FLOORS[action]

Do not treat a Noul of 0.5 as a “medium” KYC residual-text decisions score — it means yes and no are equally likely. Conjunctions stay in your code.

Guardrails and escalation

TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For KYC residual-text decisions, treat auto_approve_account as the high bar (opening an account or attesting identity). Tune on labels — see offline evaluation.

Band around 0.5 on narrative_consistent always reviews. Do not copy 0.80 onto Choice confidence.

Evaluation and rollout notes

• False-proceed on planted contradictory narratives (must stay below your SLA)
• Analyst override rate
• Calls skipped because vendor already failed — those are successes of the fail-closed path

Fit loop: pin jev-1.13.0 → replay → plot error vs confidence → pick floors where auto-act error ≤ your SLA. 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

Should auto_approve_account use 0.9 everywhere? No. Over-gating hides calibration and dumps the queue on humans. Fit per action.

Can I reuse a Noul τ as Choice confidence? No. Jaggedness: they are not interchangeable. See confidence.

Where is the rest of the KYC pack? Start with KYC decision workflow and KYC human handoff. Cluster hub: Use cases.

Can Jev replace Jumio / Onfido / our list provider? No. Keep the vendor of record. This page is leftover text triage. See Jev vs KYC vendors.

Is this legal advice or a KYC certification? No. Unofficial field notes. Counsel and your program own attestation.

What this page does not claim

• Not a substitute for KYC/AML programs.
• No pass-rate or false-accept claims.
• Not official TypeSafe.
• Official TypeSafe status, or that jev.pro issues API keys.
• That a schema-constrained answer is automatically factually correct.
