Legal failure modes with Jev

Intake forms and emails mix contract, employment, privacy, and “please just send a letter.” Counsel still owns advice. Jev routes the text you already collected after your privilege/PII filter. It does not draft opinions or file anything.

This unofficial page is the failure modes slice of the legal intake routing pack. Intent: apply the Jev (TypeSafe System One) decision model to legal intake routing failure modes. Primary search language: Legal Jev failure modes. 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): Matter-type + privilege-risk Noul on redacted text — not a clone of a legal-intake SaaS page or “AI lawyer” voice.

Legal intake routing breaks in product-specific ways. This page lists those modes so you can write tests — not a generic “AI can be wrong” essay, and not a rival limitations-page clone.

Hub: Use cases. Compare, when the other tool is the real job: legal intake.

Failure Modes inputs

Many failures start as contract violations (distractors, missing intake narrative (redacted) text). Canonical shape:

{
  "intake": { "id": "m-302", "text": "Vendor wants to use our logs to train models; need redlines this week." },
  "playbook": { "privacy": "Training-on-logs or model-training clauses → privacy_queue." },
  "meta": { "requestor_role": "procurement", "deadline_band": "this_week" }
}

Decision signals and actions

HTTP vs application:

You see Class Legal move
401 / 422 / 429 / 529 Documented HTTP Fix key/body or back off — errors
200 + flat confidence or Noul ≈ 0.5 Low confidence Hold; do not send work product externally or close the matter
Empty gather Missing evidence Skip Jev or ask “is enough information present?”

Do not treat a Noul of 0.5 as a “medium” legal intake routing score — it means yes and no are equally likely. Conjunctions stay in your code.

Guardrails and escalation

Fail closed: do not send work product externally or close the matter. Schema-safe answers are not factual correctness. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For legal intake routing, treat auto_send_external as the high bar (sending work product outside the firm or closing a matter). Tune on labels — see offline evaluation.

Evaluation and rollout notes

Your canary set should include each bullet above.

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

If the API returns 200, is the decision good? 200 only means the call parsed. Low confidence, Noul ≈ 0.5, or a policy miss are application failures.

Where do official weaknesses live? TypeSafe’s jev-1.13 jaggedness note — distractors, arithmetic, adversarial content. We do not invent more.

Where is the rest of the Legal pack? Start with Legal evaluation and Legal decision workflow. Cluster hub: Use cases.

Is this legal advice? No. Independent routing notes only. Counsel owns advice. Confirm facts on docs.typesafe.ai.

Can Jev write the contract redline? Not in this pack. Generation is a different job; keep this URL as typed routing.
