MU: balanceOf() is 1.000074823x away from share-equivalents

MU reports uiMultiplier() = 1000074823219171086 (1.000074823). 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 0.0075% (the true count is 1.0001x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

0.75 bps · 0.0075%

totalSupply raw 4525.0483 tokens vs 4525.3869 share-equivalents (delta 0.3386). Presenting the raw balance as a share count understates by 0.0075%; equivalently the true count is 1.0001x the raw.

Reproduce this yourself:

cast call 0xfF080c8ce2E5feadaCa0Da81314Ae59D232d4afD "uiMultiplier()" \
  --block 69099969 \
  --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.
