The wcc test drivers ran `ww build <bare-/tmp src>` with no -o, so the compiler's <stem>.sepwork scratch landed beside the source and was never cleaned: unbounded /tmp growth (2195 stale dirs observed) that fills tmpfs and fabricates phantom test failures + silent harness aborts, and for in-repo fixture builds leaked .sepwork into the tracked tree. Each leaking build now writes its source + output inside a per-invocation tmpdir, passes -o <tmpdir>/<stem> so the .sepwork lands inside it, and rm -rf's the tmpdir on every exit path -- including fopen-fail and the expected-fail reject builds (scratch is mkdir'd before the build can fail). `ww run` and explicit-`-o`/byte-id helpers are left as-is; the 990/993 byte-id comparison logic is byte-for-byte unchanged. Two items filed separately (this commit holds the no-Makefile / no-main.c rail): - #13: a stale <src>.s byte-id readback (749) silently no-ops since separate-compile emits .s to <ostem>.sepwork/__root.s; documented inline. - #14: build-system Makefile recipes build selfhost/cmd/*/main.ww with no -o and leak main.sepwork in-tree (bounded, gitignored; own commit). One concern -- sepwork leak hygiene -- across 228 drivers; uniform transform applied per-file and two-round reviewed. make test: all 402 passed, zero net-new /tmp scratch, zero test-driven in-repo .sepwork.
