JNJ: balanceOf() is 1.000021490x away from share-equivalents

JNJ reports uiMultiplier() = 1000021490286701962 (1.000021490). 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 0.0021% (the true count is 1.0000x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

0.21 bps · 0.0021%

totalSupply raw 1019.3490 tokens vs 1019.3709 share-equivalents (delta 0.0219). Presenting the raw balance as a share count understates by 0.0021%; equivalently the true count is 1.0000x the raw.

Reproduce this yourself:

cast call 0x03DfbBE0AC4E7bCDaFd08eD41A400326B77D8c80 "uiMultiplier()" \
  --block 69102455 \
  --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.
