Every surviving carrier now owns its artifacts: checked mkdir/mkdtemp/ fopen acquisition, one all-exit cleanup funnel per carrier, ENOENT- tolerant checked unlinks, exact-path deletion (rm -rf only for an owned pid-keyed dir or a .sepwork beneath one), and cleanup failure fails a passing carrier without overwriting its diagnostic. In the same pass the carriers adapt to the driver contract this branch lands: --sep and WW_PKGCACHE are gone, -S and the /tmp/ww_run_<pid> scratch contract are asserted, and rows whose runtime or reject coverage moved to test/wcc/data fixtures or test/lang @test owners are trimmed to the byte/artifact/diagnostic observations only they can make. Repair and adaptation ride together because most files interleave both in the same hunks; splitting would manufacture intermediate carrier states that never existed and cannot run against either driver.
