Module fs 

The fs builder: the base graph. Emits a node per file, typed by stat, plus a symlink edge per symlink. It does not hash — drft auto-hashes at the wiring seam (see crate::graphs).

Functions

build

Build the fs graph fragment from walked source files. Each file becomes a bare-path node carrying its type; each symlink also contributes an edge to its resolved target within the graph root.
