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.

/*
|
|
* 989_unknowndecl_reject — F14 #55: parsefile's recovery fallback
|
|
* (lib/ww/parse/parse.ww) chewed an unrecognized top-level construct to
|
|
* the next ';' WITHOUT emitting an error or bumping p.errs, so a typo'd
|
|
* keyword / stray token / stray decl was silently dropped from the AST
|
|
* and the build succeeded rc=0 with the work gone. The C twin
|
|
* (parse.c:1395-1400) emits errorf("expected top-level decl") + p->errs++
|
|
* and rejects. The fix calls errmsg in the fallback arm, aligning wwstage
|
|
* UP to cstage.
|
|
*
|
|
* Each REJECT row carries an unknown top-level construct and must FAIL to
|
|
* build on BOTH driver twins; each control is well-formed and must
|
|
* build+run. The fn-drop row is the live silent-loss case (a whole
|
|
* declared fn vanished with no diagnostic pre-fix).
|
|
*
|
|
* Rule-10: every row runs on cstage `ww` and wwstage `ww_ww`; both must
|
|
* agree. wwstage rows are gated on out/bin/ww_ww.
