"""Clone XS unit tests — issue #65. One verb. One size. Proven correct at each layer before moving to the next. C1 muse clone exits 0 — real muse CLI clones XS repo from localhost:1337 C2 file content matches push — sha256(file_bytes) == object_id for every file C3 no integrity errors — stdout/stderr clean even when exit 0 C4 commit graph is correct — log matches what was pushed C5 second clone is identical — two clones produce byte-for-byte identical trees Tests hit real infrastructure (musehub at localhost:1337, MinIO at localhost:9000).
