Security status

This software has not received an independent security audit.

The wallet-generation, backup/restore, descriptor, watch-only, signer-loading, and PSBT-signing flows have been tested, but the complete physical optical-disc workflow still needs broader hardware testing.

Test the complete workflow with disposable funds before relying on it for real custody.
