Methods, Metrics, and Controls

This page is written for technical diligence and procurement review. It defines what is measured, how claims are verified, where model limits apply, and which controls are in place versus planned.

Validation Date: March 5, 2026 (UTC) Scope: Artifact Snapshot (Binary + Static Export) Audience: Helius, Validators, Market Makers, VCs

Trust Metric Framework

Metric Family	Definition	Control Objective	Snapshot Status
Access Integrity	Unauthorized request rejection rate and key validation behavior.	Prevent unauthorized simulation and data exfiltration.	Verified
Evidence Integrity	Hash-valid packet exports for simulation artifacts.	Reproducible audit chain from request to output.	Verified
Model Transparency	Documented assumptions, confidence bounds, and known limits.	Avoid overclaiming and reduce decision misuse.	Verified
Operational Reliability	Queue completion behavior, retry semantics, and stall recovery. See Operational Reliability Controls.	Consistent production-grade job completion.	Implemented baseline controls (watchdog + restart + deploy gates)
Enterprise Governance	RBAC, release controls, incident runbooks, and SLO dashboards. See Enterprise Governance Controls.	Procurement-ready security and compliance posture.	Implemented baseline governance pack (runbooks + release controls + SLO cadence)

Verification Commands

./scripts/institutional_smoke.sh
./scripts/generate_evidence_packet.sh --scenario archival_clean --trials 500
cd evidence-packets/<run-id>
sha256sum -c checksums.sha256

Confirms health, auth boundaries, scenario catalog reachability, and v1 simulation behavior.
Generates a hash-verifiable packet (request, outputs, exports, manifest, checksums).
Supports reproducible technical diligence without ad hoc manual proof.

Method and Decision Limits

Probabilistic outputs are not certainties; confidence intervals must be presented with estimates.
Coverage is bounded by data and scenario selection; sparse fee history can weaken recommendation strength.
Artifact snapshot does not by itself prove full production controls such as RBAC enforcement, release signing pipeline policy, or full queue durability guarantees.

Legal and Policy Controls

Policy	Purpose	Location
Privacy Policy	Defines data handling, retention, and disclosure boundaries.	/privacy-policy.html
Terms of Service	Defines commercial use terms, disclaimers, and liability boundaries.	/terms-of-service.html
Security Policy	Defines security commitments, disclosure workflow, and response posture.	/security-policy.html
