This report came up in the forum and I can confirm that a Scratch variable set in a Shortcode does not render when called from the template of its Parent Page.

The Scratch variable is rendered on first load of the local server in fast rendering mode.

However if --disabelFastRender is used then the variable is not rendered.

Also the variable is not rendered when the command hugo is executed.

Repo to reproduce: https://github.com/Oliver-Fish/hugo-scratchpad

Since Shortcodes are rendered first, I would expect a Scratchpad set in a Shortcode to be available from a Parent Page's template.
