Route pushes through scripts/git/sign-push.sh so the operator's GPG key
stays outside the sandbox. Script signs only @{u}..HEAD (or merge-base
with origin/main|master on first push), skips re-signing when all
commits already carry a good signature, and uses --force-with-lease on
rewritten history. settings.json denies git push*, git send-pack*, and
make sign-push* so the agent cannot trigger a push path directly.
CLAUDE.md instructs the agent to hand off to the operator instead.
