Deep into my thing, lots of errors and trouble-shooting, days later: “no, caffeine deploys in an environment that doesn’t permit backend canisters to communicate with ryjl3-tyaaa-aaaaa-aaaba-cai”. Are caffeine apps severed from all ledgers? That sucks. No chainkeys? Ah!! I needed an escrow, 
Never mind. We’ll push through this. I’m assuming we just deploy an escrow on ICP mainnet…
Claude can do anything try that maybe it will work.
DFINITY has shut down caffeine apparently. They have now hopped on to a new train called Cloud Engines
