# Capture the agent's work as the submission artifact.
#
# Diffing {base}..HEAD alone captures only COMMITTED work, and agents routinely
# edit files without committing — that silently submits an empty patch and the
# grader scores the pristine base repo (indistinguishable from a no-op agent).
# So stage everything first and diff the INDEX against the base commit, which
# picks up committed and uncommitted changes alike. Same approach the benchmark's own
# sandbox uses in submit_diff().
