The typed-data screen listed a Permit or Permit2 signature as plain
key/value lines, like a sign-in message. It now shows a red warning for
them naming the spender and each token and amount, read only from the
fields the signed type declares (a Permit's token is the domain's
verifyingContract); anything those fields do not give reads Unknown.
The screen printed the page's primaryType, but ethers signs the type it
derives from types. It now shows that type, and refuses typed data whose
stated type is missing or differs: error line, Sign disabled, checked
again where signing starts.
Deviation: the warning names no deadline or expiry; see the issue.
Judgement call: DAI's older permit and Permit2's batch and witness
transfer types are recognised too.
Model: opus-5-5
