Merge branch 'release-assertions-v9.26.5'
What changed, and why it matters
This commit adds signed release assertions for BitBox02 firmware version 9.26.5. These are text files plus cryptographic signatures that record the expected SHA-256 hash of the compiled firmware. They are part of the reproducible-build verification process and do not change any firmware code, wallet logic, or device behavior. There is no security vulnerability here.
No action required. This is a routine release attestation commit. Reviewers may optionally verify the recorded SHA-256 hashes against reproducible builds of firmware/v9.26.5 and confirm the signatures are valid and from a trusted release signer.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit merges release assertion artifacts for firmware tag firmware/v9.26.5 (commit 4745c8414e81cbb0cb0b6dc8e41c599490ab2621). It adds two assertion text files (Bitcoin-only and Multi editions) stating the sha256sum of the resulting firmware binary, plus detached signatures by ‘benma’. The diff contains only these release metadata files; no source code, build scripts, or configuration files are modified.
