Didn't ship anything - was getting back from being out of office and then was doing some (mainly unsuccessful) tinkering with local models. Spent today rebasing #1446 which also needs some adjustments to adopt changes from master, should have that pushed tomorrow.

Focus

• Rebasing Non-blocking Interface for Payjoin State Machine  #1446
• Reach out to Zeus and Blue wallet to kick of conversations around implementing payjoin
• Issue review

Bottleneck
