Yes, you're right, some manual intervention is necessary. Is this what
you mean with "to transform the spec  into a statement
contract at the call point"?
However, my code doesn't have loops, so most steps are quite easy.

I've done some experiments with the WP and RTE plugins, but so far I
can't verify code that verifies with Jessie.

What are the differences between what the RTE plugin does for WP and
what the apron library does for Jessie?
