MSFT: balanceOf() is 1.000412953x away from share-equivalents

MSFT reports uiMultiplier() = 1000412952576205964 (1.000412953). 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 0.0413% (the true count is 1.0004x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

4.13 bps · 0.0413%

totalSupply raw 5923.0888 tokens vs 5925.5348 share-equivalents (delta 2.4460). Presenting the raw balance as a share count understates by 0.0413%; equivalently the true count is 1.0004x the raw.

Reproduce this yourself:

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.
