The world host must enable that optional WASI function.
The tests pass explicit `-C` paths.
## Identity
The host creates `/etc/gitconfig` when it is absent.
It sets `user.name = Sausage` and `user.email = sausage@localhost`.
Git reads this system configuration unless `GIT_CONFIG_NOSYSTEM` disables it.
Local repository configuration overrides these defaults. The host preserves an existing system configuration.
The `Sausage-Conversation` trailer retains conversation attribution.
Reflog-only operations use a fallback committer when no identity exists.
They include reset, checkout, branch changes, and reference updates.
New commits and annotated tags still require an identity.
