## Tools (as reported by the server, not verified)

- `submit\_incident`: Submit an AI incident for deterministic causal liability attribution. Returns a signed CausalCertificate, per-agent liability allocation, evidence-chain completeness, regulatory mapping, and \(where keys are configured\) a Bitcoin-anchored proof. Cost: 50 credits. Three guardrails apply: PII scan, det
- `verify\_certificate`: Independently verify a CausalCertificate end-to-end \(signature, Merkle integrity, issuer status against the registry\). Cost: 1 credit. In production env, certificates from non-active issuers are rejected.
- `verify\_certificate\_recompute`: Independently re-derive a CausalCertificate from its canonical input and compare byte-for-byte against the claimed certificate. This is the strongest verification path: it requires no trust in the issuer or signing key. Cost: 1 credit \(same price as verify\_certificate\). Returns PASS only if every ch
- `submit\_otel\_trace`: Convert an OpenTelemetry OTLP JSON trace into a FaultKey incident and return the same deterministic CausalCertificate as submit\_incident. Each span becomes an event; service.name groups spans into agents; W3C trace\_id and span\_id propagate as evidence pointers on the causal graph edges. Cost: 50 cre
- `simulate\_remediation`: Counterfactual remediation simulator. Given a certificate's verdict + fourFactorScoring + agents and a list of remediation IDs from the FK-METHOD-2026-003 catalog, return the apportioned shares each remediation would have produced \(in isolation\) and the composite shares if they all stack. Every reme
- `query\_jurisdiction\_overlay`: Multi-jurisdiction overlay \(FK-METHOD-2026-004\). Given a canonical attributable apportionment \(party-id -\> share\), the union of all jurisdiction role tags on each actor, and the union of jurisdiction-specific flags, return side-by-side post-overlay shares for AU, EU, US, UK, CA \(or a chosen subset\)
- `evaluate\_prospective\_response`: Deterministic prospective-evaluation gate \(FK-METHOD-2026-006\). Pass a ProposedAction BEFORE the agent delivers a response; receive one of three verdicts: 'allow', 'require\_revision' \(with specific factor-keyed directives\), or 'block'. Uses the same four-factor engine that issues post-hoc certificat
- `get\_anchor\_status`: Return the index of all CausalLayer Tessera anchor batches, or one batch's full JSON \(signed Merkle root, leaves, OpenTimestamps proof reference\). FREE.
- `query\_issuer\_registry`: Return the CausalLayer issuer registry, or one issuer record. The registry lists all trusted public-key fingerprints, key algorithms, validity windows, and the anchor-log repo for each active issuer. FREE — no API key required.
- `extract\_incident`: Claude-powered structured extractor. Parses unstructured text \(news articles, court filings, emails, PDFs, incident reports, logs\) into the typed JSON schema required by submit\_incident. Returns a ready-to-submit incident object with extracted agents, events, severity, jurisdiction, and financial im
