That's unusual - why the "4"? Directories with read but no search (1)
are of limited use. (Not none - it's only unusual, not insane).

| Script ownership: "lesser user"; permissions 755
| Daemon ownership: root; permissions: 755 (always started by root).

And the script/daemon _runs_ as the "lesser user"?

If so, superficially the permissions look like they should work.

I couldn't think of anything else to do with it, so I put it on the web.
