Market Support Node
Provides bounded starter quotes, RFQ quote support for biding requests, and price-surface continuity in selected Micro-markets. This is the node-capacity form of the cold-start market-maker role, not a permanent principal-trading business.
Verification Service Node
Performs operational verification for daily trading: source-chain checks, ownership and rights signals, schema conformity, freshness plausibility, duplicate-risk flags, and delivery readiness. It does not certify non-challengeable truth.
Distribution / Routing Node
Routes RequestBriefs, matches capabilities, scores route-time quality, and pushes supply toward the right buyer workflow. This capacity improves clearing efficiency without crossing into adjudication or policy enforcement.
Challenger / Jury Service Node
Handles dispute intake, bonded challenges, question-set application, and case-specific Jury Review. It is the formal adjudication path when a Pack, delivery, or Response Offer becomes contested.
Governance Participant
Tunes slow variables such as challenge bonds, corridor thresholds, node eligibility, fee bands, incentive budgets, and question-set versions. Governance shapes parameters; it does not decide live cases by sentiment.
Platform Boundary Operator
Enforces irreducible Red-corridor boundaries such as sanctions, MNPI, rights blocks, and emergency restrictions. This role stays outside ordinary network adjudication even in the mature form.
