NOMOS

Check whether an AI decision is allowed, denied, or needs escalation according to a sealed NOMOS governance artifact. Always returns `allowed` (boolean) — that field is safe to read regardless of which artifact type answered. The rest of the shape genuinely differs by artifact type, because it proxies two different underlying endpoints: pub_ demo artifacts return a flat shape (`outcome`: auto_approved/auto_rejected/escalated, `rule_applied`, `rule_reference`, flat `confidence` and `audit_hash`); your own sealed artifacts from Studio return a nested shape (`verdict`: approved/rejected/escalated, a nested `rule` object, and nested `confidence`/`audit`/`performance` objects). See outputSchema for both exact shapes — do not assume one without checking which kind of artifact_id was passed. Use artifact IDs starting with pub_ for public demo artifacts that require no API key: pub_lending_v1 (loan approval), pub_refund_v1 (refund policy), pub_fraud_v1 (fraud detection), pub_hr_leave_v1 (HR leave approval), pub_kyc_v1 (KYC/identity).

Convert one or more policy documents into a sealed NOMOS governance artifact (.nomos). Extracts executable rules using Claude, detects contradictions between rules, computes an Autonomy Readiness Index (ARI) score (0–1), and cryptographically seals the result. Returns an artifact_id you can use with verify_decision immediately. Optionally accepts historical behavioral decision logs to add a behavioral evidence layer and reach CERTIFIED confidence tier.

Analyze policy documents (and optional behavioral decision logs) to detect contradictions, hidden rules, and gaps between declared policy and observed behavior. Stateless — no artifact is created and nothing is persisted. Returns contradiction types: threshold_conflicts (numeric rule overlaps), ghost_terms (undefined terms used in rules), role_conflicts (same action allowed by one role, denied by another), rule_collisions (direct logical conflicts), and layer_divergences (policy says X but behavioral data shows Y).

Query a published authority on the NOMOS Exchange marketplace — a different system from verify_decision's own sealed policies. Every public authority (e.g. eu-ai-act.nomos) is queryable with no key. Returns the authority's own verdict (AUTHORIZED/DENIED/ESCALATED), the exact rule and reason, and a permanent, cryptographically-bound transcript (query_id + url) — replayable evidence, not just a reply. Nothing is invented or paraphrased: the verdict is the authority's sealed rules evaluated against your inputs. The default response is a short, curated summary (verdict, matched rule, source citation when the artifact has one, transparency/completeness disclosures, transcript link) — not the full rule-by-rule evaluation trace. Set include_evaluation_trace: true to get that complete diagnostic record when you or the user actually need it.
