The short version

What changed, and why it matters

This commit only updates the release signature file. It adds two new cryptographic signatures for COLDCARD Mk4 firmware version 5.4.4 and refreshes the PGP signature that covers the entire file. There are no code changes, no bug fixes, and no security-relevant behavior changes in the firmware itself.

Recommended action

No action required. Verify the new PGP signature as part of normal release-process checks if you distribute or mirror the signatures file.

Security signals we found

No strong security signals were identified.

This commit only adds a new automated test to the COLDCARD firmware test suite. The test checks that when a user tries to sign a text file containing valid JSON that is not a JSON object (for example, a plain number, string, null, or list)…
