The short version

What changed, and why it matters

This commit only changes test data and expected screen fingerprints for Trezor's Ethereum EIP-7702 signing tests. It replaces one test case that used a nonce of 0 with the same scenario using a nonce of 67, because the real-world protocol rule requires the tuple nonce to be non-zero. No production firmware code is modified, so this commit does not fix or introduce a security vulnerability in shipped devices.

Recommended action

No action required; treat as a routine test maintenance commit. If reviewing a related EIP-7702 implementation, verify separately that the production code already rejects nonce 0, since this commit only updates tests and does not change validation logic.

Security signals we found

01

Test-only change with no production code modification

02

EIP-7702 tuple nonce constraint reflected in test data

03

Expected UI test hashes regenerated for renamed test vector
