MGS7005: directory not in the graph

magus\dir(path) returns the typed Dir record for one workspace directory: its layer, language, imports, importers and declared calls. Figures build their boxes from these records rather than from path strings.

This code fires when no directory node matches the path.

Why

An empty record for a misspelled path would draw a box with no edges and no drift, which looks like a quiet package. Raising makes the typo fail where it was written.

Resolution

• A typo. Correct the path; it is workspace-relative, with no leading ./.
• A directory outside every project. Declare a project that covers it, or draw it as an external box that names no directory.
• A stale graph. Run magus graph build after adding the directory.
