Key rotation (May 2026)
The previous key (4A3762B5 01BA3B89 48CA0FD0 39EED3B0 80D10556) has been retired. Backup access was lost in a system migration; no further attestations will be signed with it, and anything encrypted to it can no longer be read. If you sent me an encrypted message using that key, please re-send it encrypted to the current key below. The full signed rotation announcement is pinned on X (@btcqna).
