The wrap-up script stages dirty *tracked* files, so every newly created
file in the multi-group change -- the group-id module, the membership
verifier, their tests, the isolation scenario and prime_profile.sh --
was listed as untracked and then left behind. The tree compiled locally
because the files exist on disk; CI checked out a repo where config.py
imported signal_bot.groups and nothing provided it.
