The short version

What changed, and why it matters

This commit rewrites the device factory-reset routine from C to Rust. It is a straightforward language port: the same steps (lock keystore, reset secure-chip keys, reset U2F counter, wipe memory, disable SmartEEPROM, show a status screen, reboot) are preserved. The change also adds unit tests and makes the unlock function asynchronous so it can call the new async reset. Nothing in the diff introduces a new vulnerability or changes security-critical behavior in a suspicious way.

Recommended action

No security action required. Treat as a normal refactoring commit. Reviewers may optionally verify that the Rust abort() helper behaves identically to the C Abort() for the three fatal error paths (secure chip reset failure, U2F counter init failure, memory reset failure).

Security signals we found

01

No new security-relevant behavior introduced

02

Existing security operations preserved during C-to-Rust port

03

Added unit-test coverage for reset retry and status display

04

Made unlock() async to accommodate async reset()

05

Removed direct C abort paths from reset_reset; Rust uses abort() helper for the same fatal errors
