description: "Reconciles Robinhood Chain stock-token corporate actions against the ERC-8056 scaled UI amount surface. Stock tokens never rebase; splits and dividends land as a uiMultiplier() change plus a UIMultiplierUpdated event while raw balanceOf stays static until redemption. Checks declared corporate-action ratio against the multiplier transition, monotonic event sequencing, and raw-balance invariance. First tooling anywhere for ERC-8056 reconciliation. Zero network, zero PII."
