Complicated systems are surprising! Somehow each little step wasn't
completely crazy and yet there must be a lesson in here
somewhere. :)

Ah! I didn’t know about the module browser, thanks! And I guess this chain
makes sense.

If you open a file that requires scribble/manual with the module browser
(available via the Racket menu item in DrRacket), you'll see that ssl is
needed by the code that opens urls (presumably to do https) which is needed
by the code that handles planet requires (since planet requires may involve
I don't know if Scribble needs OpenSSL, but a dependency probably does. The
only precondition of that error is that openssl/mzssl appears *somewhere* among
the dependencies. I run into that same error for evaluators that have nothing
to do with Scribble.

Thanks for the explanation.
I can't figure out why scribble/manual needs openssl, but oh well.
After reading through openssl, I've gone with a slightly less blunt instrument:

Heads up: My earlier example was missing a closing paren. Also just saw that
your subject line asked "Why", so I checked.
openssl/mzssl provides a parameter called `ssl-default-verify-sources'. See
[1]. The parameter is created during module instantiation with a OS-dependent
default value.
If you just want to silence the error with a blunt instrument, then you could
try a parameterization where sandbox-path-permissions is set to:
(append (map (λ (p) `(exists ,p)) (filesystem-root-list)
(sandbox-path-permissions)))
This suffices since it is an existential check, not a file
I have a sandbox that loads scribble/manual (indirectly) to render some HTML.
But it crashes with the following error:

file-exists?: `exists' access denied for /etc/ssl/cert.pem
