Provision the repository and Drive folder — a separate step today

The browser form does not provision the Project's repository or Drive folder by itself. Every other way of opening a Project — the JSON API, the CLI, the MCP tool — provisions both surfaces as part of opening; the browser form only writes the matter row. Immediately after submitting, /app/projects/<code> names no repository yet.

Close that gap from the matter page's admin retry, or from the CLI:

navigator site projects surfaces reconcile --project <code>

This creates — or adopts, if one already exists — an empty private GitHub repository and Drive folder, and records the repository URL on the row. It writes no files.
