Will your multisig backup still recover after the next firmware update?
A versioned, cross-vendor test corpus of Bitcoin multisig recovery packages, so a signer or coordinator upgrade never silently breaks a user's recovery path.
Who it is for
Hardware-wallet vendors, multisig coordinator developers and QA leads shipping releases that touch descriptors, PSBTs or backup formats.
What it will do
Real-world recovery fixtures (descriptors, wallet configs, PSBTs) across signers
Run them in CI against each release candidate
Get a clear pass/fail report per vendor and version
Contribute sanitized failure cases back to the shared corpus
