Opening a project never runs project-supplied code. This function is the explicit, opt-in path to restore executors stored as source text in the project's runtime manifest.
Details
With trust = FALSE (the default) the stored source for each kind is
printed and the function aborts, so the user can review what would be
evaluated before proceeding. With trust = TRUE each source string is
evaluated in a child of globalenv() (not in the bayesgrove namespace)
and a warning notes that closures over the original environment are not
restored.
