What changed, and why it matters
This commit only updates two automatically-generated timestamp files used to set dates on files created by the COLDCARD hardware wallet. It changes the recorded build date from March 5, 2026 to June 30, 2026, and bumps the firmware version numbers from 5.5.0 to 5.5.1 (MK4) and 1.4.0Q to 1.4.1Q (Q1). There is no security-relevant code change.
No security action needed. Treat as routine build metadata update.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies stm32/COLDCARD_MK4/file_time.c and stm32/COLDCARD_Q1/file_time.c, which override the MicroPython FATFS get_fattime() port function. The changes update the hardcoded FAT timestamp constants and version comments to reflect a new build date and minor version bump. No functional logic, parsing, cryptography, or privilege handling is altered.
