## Summary - keep Git metadata/status subprocesses independent of repository `core.fsmonitor` configuration - preserve existing working-tree state reporting while making the helper behavior more predictable - add regression coverage for `get_has_changes` when a repository defines an fsmonitor command ## Validation - `cargo fmt --all` - `cargo test -p codex-core test_get_has_changes_` - `cargo test -p codex-git-utils`
codex-git-utils
Helpers for interacting with git, including patch application. The crate also
exposes a lightweight baseline API for internal directories that use git only
as a resettable diff mechanism: ensure_git_baseline_repository preserves a
usable root/.git baseline or creates one when it is missing or unusable,
reset_git_repository replaces root/.git with a fresh one-commit baseline,
and diff_since_latest_init returns structured file changes plus a unified
diff from that baseline to the current directory contents.
