refactor(core/embed): reorganize error handling

This commit is a code cleanup that moves how Trezor firmware handles fatal errors and shutdowns between its internal software layers. It does not add new user-facing features or change security protections. The main risk is that reorganizi…

feat(core/rust): separate trezor-crypto to its own Rust crate

This commit is a large but straightforward internal refactoring: the cryptographic code is moved from one Rust crate (`rtl`) into a new dedicated crate (`crypto`), and all project dependencies are updated to point to the new crate. The act…

style(core/rust): apply uniform import grouping

This is a purely cosmetic code-style commit. It runs the project's Rust formatter across hundreds of files, changing only how import statements are grouped and how long comments are wrapped. No program logic, security behavior, or function…

build(core): avoid unused variable warning in rng_fill_buffer_strong

This is a minor build cleanup. A developer added a compile-time branch so that when neither the Optiga nor Tropic security chips are used, the 'strong' random-number wrapper simply calls the normal random-number function and returns. The o…

build: prevent uv from using packages newer than 30 days

This commit is a hardening change to Trezor's build tooling. It tells the Python package manager 'uv' not to use any package uploaded to PyPI in the last 30 days, which reduces the risk of accidentally pulling in a freshly compromised depe…

refactor(python): rework session-based API

This is a large internal refactoring of the Python trezorlib client API. It reworks how sessions are created, managed, and closed, moves session classes out of the transport layer, adds a credential/keyring helper for the new THP pairing f…

fix(python): improve session handling and unlocking

This commit refactors how the Trezor Python command-line tool (trezorctl) manages device sessions and unlocking. It aims to avoid creating duplicate sessions when unlocking the device and to handle passphrases more cleanly. The changes are…

style(core): update types to pyright 1.1.404

This is a large code-style and type-annotation cleanup. It replaces concrete type hints like `bytes` with broader aliases such as `AnyBytes`, `AnyBuffer`, and `StrOrBytes`, and fixes a few minor type-checker warnings (for example adding an…

style: update to black 25 style, silence new flake8 warnings

This commit is purely a code-style update. It reformats Python source files to match the latest version of the Black formatter, changes uppercase hex escapes in byte strings to lowercase, removes unnecessary 'global' declarations, and adju…

feat(core): implement fingerprint logic for BootloaderV2 image

This commit updates a small Python helper script used to display a fingerprint (a kind of checksum) for Trezor firmware files. It adds support for a newer bootloader image format (BootloaderV2) so the tool can handle both old and new forma…
