What changed, and why it matters
This commit only updates test screenshot snapshots for the Ledger Bitcoin app. It renames and replaces image files used by the Ragger automated UI testing framework, changing test case names from '4to17' and '4to18' to '4toMax' and '4toMaxPlus1'. No application source code, firmware, or runtime behavior is modified, so there is no direct security impact on users.
No security action required. Treat as routine test maintenance. If reviewing for a release, verify that the corresponding source-code/test-code changes that necessitated these snapshot updates are separately reviewed.
Security signals we found
No source-code changes
Only test fixture / snapshot images modified
No cryptographic, parsing, or UI logic changed
No vendor security disclosure or advisory referenced
Evidence from the diff
The diff consists entirely of binary PNG file changes under tests/snapshots/ for multiple device families (apex_p, flex, nanosp, nanox, stax). Old snapshots for test_sign_psbt_singlesig_wpkh_4to17_ and test_sign_psbt_singlesig_wpkh_4to18_ are deleted, and new snapshots for test_sign_psbt_singlesig_wpkh_4toMax_ and test_sign_psbt_singlesig_wpkh_4toMaxPlus1_ are added. The actual pixel content appears to be reused/reorganized (identical blob hashes move between paths). No C/source code, build system, APDU handlers, cryptographic logic, or transaction parsing code is touched.
