@benalleng

• Moved to new apartment
• health check failed twice in a row why? @spacebear21 says it's maybe a network connection
• hoping to get internet next week
• getting Liana things ready for their new sprint which ends next week
• Is Liana open to bumping MSRV? Rust bitcoin, BDK holding back to 1.74, 1.85. If we really wanted to we could roll back to 1.74 but we'd have to bump dips. UniFFI might break since 0.29 uses aggressive MSRV. We might need to split back up if we downgrade. Ben will get a definitive answer.
• Dan wonders about URL dependency. Might we roll our own?
• not sure what's exposed with lianad enough to know for sure if it's possible.
• Liana is the priority
