Run this one command in Terminal on your laptop before you lose wifi:
curl -fsSL https://calvinland-export.pages.dev/reassemble.sh | bash
Then: open Minecraft → Singleplayer → CalvinLand.
This link always serves whatever state the world was in the LAST time someone
ran export-for-flight.sh on Calvin. It is not automatically kept fresh, so if
this is stale, ask Claude to refresh it, or run:
ssh calvin '/Users/calvin/servers/minecraft-java/export-for-flight.sh'
Manual fallback: download all parts below into one folder, then
cat CalvinLand-part-* > CalvinLand.tar.gz && tar -xzf CalvinLand.tar.gz -C ~/Library/Application\ Support/minecraft/saves/
