You want to put a file in, get one back, or recover something you overwrote.
Files in Fulcra are versioned. Uploading to a path that already exists keeps the earlier version rather than replacing it, and a delete can be restored. Each file is encrypted at rest with its own key, and any file type can be stored.
You can work with them in Context Web, from the command line, or over HTTP. Whichever route you use, your agents see the same files.
