You have documents, exports and folders that matter to your work, and your agents can't see any of them.
Fulcra can hold them. It works as a secure file store: files are versioned, so writing to a path that already exists keeps the earlier version rather than overwriting it, and a delete can be restored. Each file is encrypted at rest with its own key.
That makes it a safe place to keep something, and a safe place to let an agent write. You can reach your files from Context Web, from the command line, or over HTTP.
