rerun 2026-10-12T23:36:40Z to 23:36:46Z, after the two tests added for duplicate-key-ok and clone-in-place; the three lines of mutants.sh, same mut.mjs
duplicate-key-ok: killed (ℹ fail 2; a clone the session rigged is kept, and git runs nothing and writes nothing outside it|the origin url twice, both the root)
merge-not-ff-only: survived
clone-in-place: killed (ℹ fail 1; the clone is not at its place until git clone has finished)
