createPage always failed with "generateJSON can only be used in a Node
environment". Root cause: the MCP module (packages/mcp/.../collaboration.ts)
sets `global.window = dom.window` (jsdom) at load time and is imported
in-process by the server's AI-chat tools, leaking a global `window` into the
Node process. The server's self-contained ProseMirror helpers guarded with
`if (typeof window !== 'undefined') throw`, which then became a false positive
and broke POST /pages/import (the endpoint createPage calls).
- server: drop the vestigial `typeof window` guard in generateJSON.ts and
generateHTML.ts; both helpers create their own happy-dom Window and never
read the global one. Replace it with an explanatory comment.
- mcp: in DocmostClient.getPage, pass the resolved UUID (resultData.id) to
listSidebarPages instead of the original pageId, which may be a slugId and
triggered a Postgres "invalid input syntax for type uuid" (and a silent
empty subpages list).
