BoLD Challenge-Window Finality Classifier

Robinhood Chain is Arbitrum Orbit with BoLD interactive fraud proofs. Settlement inside the roughly week-long challenge window is optimistic, not final. This node classifies a finality claim as soft, posted, challengeable, or final, and flags claims of final finality made while the challenge window is still open. Client-side. Zero PII.

This classifier is pinned to one named deployment and to the BoLD interactive fraud-proof model. ART-492 Settlement Finality Classifier is the vendor-neutral equivalent: it takes the challenge window and the settlement parameters as inputs rather than assuming a deployment, and it carries separate tier ladders for optimistic challenge windows, validity proofs and single-slot BFT consensus. Use ART-492 when the deployment is not fixed in advance. This page stays live and unchanged, so receipts it has already produced remain verifiable.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

Run the AINumbers MCP tool `classify_bold_challenge_finality`. Task: Classify a settlement-finality claim on Robinhood Chain into soft, posted, challengeable, or final relative to the BoLD challenge window.
Call it with arguments: {"policy_parameters":{"l2_inclusion_timestamp":100,"batch_posted_to_l1":true,"assertion_created":true,"assertion_created_timestamp":1000,"current_time":701000,"finality_claim":"final"}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
