Hi!
I submitted a PR #4 with a solution to the challenge. Ran so fast that misplaced where should I put the prover reports and put them in the PR. Pasting them also here:

A run of the new BordaMissingRule.spec on the original Borda.sol that is verified is here

A run of Borda.spec on BordaNewBug.sol showing the existing spec misses the bug is here

Reports of all previously acknowledged bounty specs on BordaNewBug.sol, these specs will be found in the bounty_specs folder: none

A run of BordaMissingRule.spec on BordaNewBug.sol showing your rule catches the bug is here

It was really fun, learned a bunch on CVL grammar and invariant thinking. Thanks a lot :)
