Incident response audit trail with Jev
Prometheus rules and PagerDuty already page on numeric thresholds. Jev is optional on messy customer-reported incidents or multi-alert narratives: which SEV band, which runbook class? It does not roll back deploys or page people.
This unofficial page is the audit trail slice of the incident response classification pack. Intent: apply the Jev (TypeSafe System One) decision model to incident response classification audit trail. Primary search language: Incident response Jev audit trail. 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): Runbooks and pagers stay; Jev classifies messy alert/customer text into SEV / runbook class, then code pages. Not a runbook-clone or status-page IA photocopy.
Incident response use-case context
An audit trail for incident response classification is a decision trace: replayable inputs, typed answers, floors, and the action the incident classifier took. It is not a chat log and not a clone of a SIEM product page.
Hub: Use cases. Compare, when the other tool is the real job: incident runbooks.
Audit Trail inputs
Persist the filtered payload (the contract), not whatever arrived at the edge:
{
"report": { "id": "INC-44", "text": "Checkout 500s since 14:02 UTC after the payments deploy. Status page still green." },
"signals": { "error_rate_bucket": "high", "payments_deploy_recent": true },
"policy": { "sev1": "SEV1 = complete checkout loss or safety." }
}Redact secrets before the object hits cold storage.
Decision signals and actions
Minimum fields:
- incident.id
- answers + pin
- pager incident id
- who was IC
- override SEV
Also store usage.input_tokens (vendor meter) and the full probabilities map — argmax-only logs cannot explain a close sev.
Do not treat a Noul of 0.5 as a “medium” incident response classification score — it means yes and no are equally likely. Conjunctions stay in your code.
Guardrails and escalation
If you cannot explain paging SEV1 / rolling back via automation from the trace, you are not ready to auto-act. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For incident response classification, treat page_sev1 as the high bar (paging SEV1 / rolling back via automation). Tune on labels — see offline evaluation.
Evaluation and rollout notes
Traces are the eval warehouse. Replay against SEV gold from ICs, runbook-class gold, and whether a page was warranted after criteria or alias changes. 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 the HTTP log enough? No. Persist the filtered state, full probabilities, floors, and downstream action as a decision trace.
May I log raw secrets? Redact in code. Jev will not be your DLP layer.
Where is the rest of the Incident response pack? Start with Incident response human handoff and Incident response evaluation. Cluster hub: Use cases.
If metrics already say critical, should we wait for Jev? No. Metrics page now. Jev is for leftover messy text. See safe defaults.
Can Jev write the status-page update? Not in this workflow. Classification only. Generation is a different job.
What this page does not claim
- Not a pager, status page, or IR retainer.
- No MTTR or uptime claims.
- Not official TypeSafe.
- Official TypeSafe status, or that jev.pro issues API keys.
- That a schema-constrained answer is automatically factually correct.
