test/run fans out test/wcc/*.c except 950 and 990-997 across $(nproc) xargs workers, then runs the byte-id gates sequentially in phase 2. Each worker writes <prefix>.status into a mktemp results dir; the collector emits them in glob order for deterministic output. Phase 2 sequentiality sidesteps the race introduced by ww_ww writing intermediates next to every traversed source (#15) — concurrent reads of selfhost/cmd/<tool>/main.{combined.ww,s,o} would see partial bytes (#16). `make test-unit` (UNIT=1) skips phase 2 entirely for a 3.8s inner-loop check; `make test` runs the full 132 in ~8:30. test-unit goal aligns with the selfhost-bootstrap project goal: 990-997 + 950 are the toolchain-rebuild gates, fast feedback is for unit work below them. 990-995 wrap every ww/w6c/w6a/w6l/wwdump invocation in `timeout 180`; 995's hardcoded /tmp/ww_d_hello.ww is now pid-keyed. 995 forks its 5 ww_ww builds concurrently (waitpid for collection) so its solo wall drops from 3:15 to 1:32. Phase-2 split (parallel readers + sequential writers) deferred to #17, post #15. Wall: 9:59 → 8:32 (full) / 3.8s (test-unit, ~158× from baseline).
