Goal: Let users inspect any visible graph node without losing their current neighborhood or viewport.
In scope: A native modal dialog; full node metadata and content; mouse and keyboard activation; Escape, close-button, and backdrop dismissal; an explicit Explore neighborhood action; interaction-contract checks; JavaScript syntax validation; and complete regression verification.
Out of scope: Graph mutation; source editing; persisted modal state; nested dialogs; arbitrary templates; external hosting; canonical writes; or any new HTTP endpoint.
Done when: Activating a graph node opens an accessible inspection dialog, dismissing it preserves the current graph, explicit exploration loads the selected neighborhood, and the complete DocForge gate passes.
Owners: DocForge owns dialog state and interaction. The configured project continues to own graph facts. The MCP process continues to own the validated snapshot and listener lifetime.
