A dependency five levels down throws, and your whole canvas goes white. CrossUI Studio's Dependency Graph still draws — zero build — points you straight at the blinking node, and then lets you inject a mock for the broken module to bring the page back. No file edit. No rebuild.
The Dependency Graph is built from static AST parsing, not a build — open a file and the import tree renders instantly, even when the canvas has completely crashed. The failing module blinks with its exact line/column. Then the part that's actually new: from the inspector you can set an interceptor or override to swap the broken dependency for a mock, hit Apply Dependency Injection, and the render comes back — rules auto-persist per entry file.
The blank-screen problem, five levels deep
A component blows up, but the component is never the culprit. Here's a real one. The canvas throws inside AIPanel.jsx:
Error (Canvas render — runtime)
