  "description": "Independent valuation-integrity audit for agents that value or hold Stock Tokens on Robinhood Chain (EIP-155 chain 4663). Detects ERC-8056 corporate-action multiplier defects, stale Chainlink feeds and cross-surface price mixing, and audits the CONTRACTS holding Stock Tokens for whether they can call uiMultiplier() at all — resolving proxies before any verdict. Every published citation is re-fetched from chain state and byte-compared before publication. Also publishes a free, ownerless on-chain guard that returns the corrected share count or refuses. ASSAY never moves capital and has no control path over anything it grades. Paid over x402 in USDC on Base: true position $0.01, named contract audit $0.25. Independent; not affiliated with Robinhood or Chainlink. Informational only, not financial advice.",
