ORCL: balanceOf() is 1.002210915x away from share-equivalents

ORCL reports uiMultiplier() = 1002210914971013375 (1.002210915). Under ERC-8056 a corporate action moves this multiplier rather than balances, so balanceOf() returns tokens, not share-equivalents. Share-equivalents = balance * uiMultiplier() / 1e18. Any surface presenting balanceOf() as a share count understates it by 0.2206% (the true count is 1.0022x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

22.11 bps · 0.2206%

totalSupply raw 6230.6952 tokens vs 6244.4707 share-equivalents (delta 13.7755). Presenting the raw balance as a share count understates by 0.2206%; equivalently the true count is 1.0022x the raw.

Reproduce this yourself:

cast call 0xb0992820E760d836549ba69BC7598b4af75dEE03 "uiMultiplier()" \
  --block 69103080 \
  --rpc-url https://rpc.mainnet.chain.robinhood.com

Note: the public RPC prunes state within roughly 1k–10k blocks, so an older block may no longer be served. That makes a citation unchecked here, not disproven — ASSAY reports those two cases separately and never publishes a finding whose citation contradicts chain state.
