Finance confidence thresholds with Jev

Invoice and spend packets arrive as messy descriptions. The ledger, tax engine, and approval matrix still own money. Jev judges policy-fit of the narrative you paste. It does not post journals or calculate tax.

This unofficial page is the confidence thresholds slice of the finance approval decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to finance approval decisions confidence thresholds. Primary search language: Finance 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): Typed exception + path questions with amounts extracted in code — not a clone of a finance-approvals product page or a rival AP-automation IA.

Finance use-case context

Thresholds turn finance approval 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 finance approval decisions hides calibration.

Hub: Use cases. Compare, when the other tool is the real job: finance approvals.

Confidence Thresholds inputs

You need (1) pinned answers on a frozen contract and (2) labels for path gold, policy-ok gold, and whether a controller would have held the packet. State shape:

{
  "packet": { "id": "ap-4401", "memo": "Rush SaaS renewal; vendor changed SKU names.", "vendor": "Acme Cloud" },
  "amounts": { "total_band": "5-15k", "currency": "USD", "extracted_ok": true },
  "policy": { "sole_source": "Sole-source allowed only with named waiver text.", "rush": "Rush = business-critical outage risk." }
}

Decision signals and actions

FLOORS = {
    "tag_path_only": 0.55,      # illustrations — replace
    "auto_approve_under_cap": 0.92,
}
NOUL_TAU = 0.85  # for policy_ok

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

Do not treat a Noul of 0.5 as a “medium” finance approval 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 finance approval decisions, treat auto_approve_under_cap as the high bar (posting an approval or payment instruction). Tune on labels — see offline evaluation.

Band around 0.5 on policy_ok always reviews. Do not copy 0.85 onto Choice confidence.

Evaluation and rollout notes

• False auto-approve on a planted sole-source canary
• False-hold rate (throughput)
• Disagreement after a policy-text edit

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_under_cap 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 Finance pack? Start with Finance decision workflow and Finance human handoff. Cluster hub: Use cases.

Can Jev replace the ERP approval matrix? No. Hard caps, SoD, and tax stay in finance systems. Jev scores the narrative remainder. See vs finance approvals.

Should we send the invoice image? No. System One state is text. Run OCR/extract elsewhere, then pass bands you trust.

What this page does not claim

• Not a ledger, tax engine, or SOX control.
• No leakage or cycle-time numbers.
• Not official TypeSafe.
• Official TypeSafe status, or that jev.pro issues API keys.
• That a schema-constrained answer is automatically factually correct.
