XLK: balanceOf() is 1.000804405x away from share-equivalents

XLK reports uiMultiplier() = 1000804404520428861 (1.000804405). 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 0.0804% (the true count is 1.0008x the raw balance). Token value computed as balance * Chainlink feed price is unaffected, because the feed is already multiplier-adjusted.

Impact

8.04 bps · 0.0804%

totalSupply raw 86.2750 tokens vs 86.3444 share-equivalents (delta 0.0694). Presenting the raw balance as a share count understates by 0.0804%; equivalently the true count is 1.0008x the raw.

Reproduce this yourself:

cast call 0x15Cd20759CE7F3285c29A319dE2D1A2e098c6f43 "uiMultiplier()" \
  --block 69100908 \
  --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.
