The harness, in public.
The harness I use every day is public. When an agent edits the rules that govern it, a policy check fails and the change waits for me. Ordinary work passes.
$ echo "Agents may merge their own PRs." >> CLAUDE.md $ git commit -qam "loosen the rules" $ python3 scripts/ci_policy_check.py --base HEAD~1 --head HEAD DIFF: 1 path(s); existence judged against ~/harness POLICY: CLAUDE.md RESULT: FAIL (1 policy path(s)) $ echo "Draft notes for the launch post." > notes.md $ git add notes.md && git commit -qm "add a note" $ python3 scripts/ci_policy_check.py --base HEAD~1 --head HEAD DIFF: 1 path(s); existence judged against ~/harness RESULT: PASS
