Git commands now ignore graft files, so a repo can't fake the commit history Claude sees.
What's wrong with this entry?
Every git subprocess on this path now runs with -c advice.graftFileDeprecated=false and GIT_GRAFT_FILE pointed at /dev/null, so a graft file in a repository cannot rewrite the commit history Claude Code sees.
- Joins the existing environment hardening:
GIT_ALLOW_PROTOCOL=none,GIT_NO_LAZY_FETCH,GIT_NO_REPLACE_OBJECTS. - Unconditional.
advice.graftFileDeprecated=false
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
