The D-on probe (wxWASM_STAR_DISPATCH=1 on top of D5) is measured and
recorded in doc 22 §10: the week's 'environmental cliff' was adopted-fiber-
stack alignment (trap 1, fixed in wx - retires the D5 entry's findings 2-3
with a mechanism); with it fixed D5+D reached 388 passed; the remaining
reds decompose into three named Phase B gaps (wake ordering on a running
context, finished-coroutine transfer livelock, invocation-aware root
routing), each with a deterministic repro suite. D parks again behind the
switch until Phase B owns coroutine lifetimes.
app-quit.spec.ts + a wx_test_quit hook in minimal_test drive a real
File->Quit-shaped exit through D5's detached teardown (loop exits on its
context, S6 latch 'clean', OnExit + wxUninitialize there) - green in the
D-on probe, closing the D5 teardown-gate open item.
Landing state (D off): coroutine + coroutine-pthread + app-quit green;
nested red at case 3 in the pre-existing doc-19 wake-window family
(cases 1-2, yesterday's blockers, now pass); races wakeup_during_transition
stays layout-sensitive. Both are the class the C+B+E flip removes.
