The brain remembers your files, connected
A task re-fetched a PDF from Gmail in a dozen calls when the file was already sitting in Downloads. Never again: files are now first-class nodes in the knowledge graph, linked to the people, apps, and subjects around them. Ask for "the renters policy pdf" or "the thing Jennifer sent me" and the graph surfaces the file, its path, and the cluster around it. Fast lookups that would have come back empty now escalate to the full graph automatically, a slower right answer instead of a fast nothing.
