Global Cache Directory

datamitsu stores data under ~/.cache/datamitsu/ (or $XDG_CACHE_HOME/datamitsu/), split into two subdirectories:

• store/ — Downloaded binaries (.bin/), runtime binaries (.runtimes/), runtime-managed app environments (.apps/), remote configs (.remote-configs/)
• cache/ — Per-project tool caches (projects/), verify state (.verify-state/)

You can view the cache path with:
