fsberlin. A file-hierarchy substrate for human–AI project collaboration. Cards are folders, waypoints are overlays, agents are first-class users; the filesystem is the lingua franca. Local-first, git-native, no lock-in — humans edit in any tool, AIs use ls/cat/rg, both read and write the same plain text.
