This commit is a test-infrastructure cleanup. It moves JavaScript code out of HTML files into a shared external file, bundles the pixelmatch image-comparison library locally instead of loading it from a CDN, and makes the UI test reports wait for images to finish loading before comparing them. There is no security-relevant change to the Trezor firmware or wallet behavior.

✓ Descriptive subject✓ Names a concrete action or component✓ Uses a recognizable type or scope! No meaningful explanatory body
AI analysis · Moderate 59/100

A function that reads firmware image headers was returning the wrong kind of error value. In C, returning a special 'false' value where a pointer is expected can confuse the rest of the program, potentially causing crashes or allowing a malformed firmware image to be treated as valid. The patch makes all error paths consistently return NULL, which is the normal 'no valid header' indicator for this function.

AI analysis · Low 43/100

This commit adjusts how the Trezor bootloader's length is calculated and pads the bootloader image to a 512-byte boundary. The old calculation added the sizes of two memory sections, which could produce a value that does not match the actual padded image size. The new calculation uses a dedicated end marker, and the linker script now explicitly fills unused space with zeros and aligns the image. This is a defensive fix in low-level firmware packaging; it does not by itself show an exploitable bug, but misaligned or incorrectly reported bootloader sizes could theoretically cause verification or update failures.

This commit fixes the horizontal centering of a small vendor logo shown on the bootloader's 'unsafe firmware' warning screen.

This commit improves error messages and logging in a Trezor production-test command file for the Tropic chip. It does not change program logic, access controls, or cryptographic checks; it only makes failures easier to diagnose by printing the actual numeric error code and correcting a misleading function name in one message. The change is in a prodtest (factory testing) tool, not in the wallet firmware that end users rely on for securing funds.

fix(legacy): allow cross-sign with ETH mainnet

Backport #5622 to legacy:

- Previously only non-standard networks (not SLIP-44 60 or 1) could cross-sign
with Ethereum mainnet. Now any network that isn't Ethereum mainnet can use
Ethereum derivation paths
- This is a workaround enabling access to networks like Hyperliquid that
have conflicting chain IDs and can't claim official SLIP-44 registration.

Also, backport legacy testnets' support from #5970.

AI analysis · Low 25/100

This commit loosens address-path validation for older Trezor (legacy) devices when signing Ethereum-style transactions. Previously, only non-standard networks could use Ethereum's mainnet derivation path; now any network except Ethereum mainnet itself can do so, and Ethereum mainnet additionally accepts testnet-style paths. The stated purpose is to support newer networks like Hyperliquid that cannot get an official coin-type registration. The change is a deliberate feature backport, not a covert bug fix, but it does relax a security-relevant boundary that normally prevents cross-network address reuse.

This is a routine build-system update that bumps the recorded version of an internal vendor package (tvl) from 2.2 to 2.3 in the Python lock file (uv.lock). The change itself is a single digit in a metadata file and contains no executable code changes, no security fixes, and no disclosed security relevance.

This is a one-line build script change that adds the '--locked' flag to a Python package manager command. It tells the build tool to refuse to proceed if its lock file is out of date, preventing accidental use of unexpected dependency versions. There is no security vulnerability or exploit here.

build(core/rust): improve panic message in debug builds

https://doc.rust-lang.org/core/panic/struct.PanicMessage.html#method.as_str should make panic's messages more helpful.

This is a small debugging improvement for Trezor's Rust firmware code. It changes panic error messages so that, in debug builds, the actual panic message text is shown instead of a generic placeholder 'rs'. There is no security vulnerability or fix here—just better diagnostic output for developers.

This change adjusts how the Trezor firmware's Rust code is built for the debug software emulator. Previously, all builds used a setting that makes the program immediately stop (abort) if a panic occurs. Now, the debug emulator keeps the normal panic mechanism so that internal debug assertions can be reported instead of silently crashing. This is a build/developer-experience change, not a fix for an exploitable security flaw in shipped hardware wallets.
