seplink_test.ww carries the .a substrate legs (root-as-.o layout, .a
byte-id + 3x determinism, the #31 masked-dup PASS-3 reject with its
non-vacuity flip), the loud dependency-cycle reject with byte-equal
cs/ww stderr, and the w6l/w6l_ww bare-main duplicate-symbol reject
(achievable substring parity per the filed message divergence).
sepimport_test.ww re-hosts the #98 colo srcd-shadow `ww test` gate,
the #99 imported-dep bare-main mangle count, the #23/#30 modfn
coexist byte-id (incl. the cross-layout vbu order pin), and the
#58/#50 scopelookuptype mod-preference rows over the checked-in and
synthesized module trees. slttypepref's ww_ww-absent skip gate is
dropped: the Make target declares both drivers (mangle_test
precedent).
Birth test/sep/ (single-file ww observers on test/testenv, run by the
new SEP_WW_TARGETS pattern rule under test-compiler) with
sepbuild_test.ww: the build_one_sep real-chain gate incl. the
bodies==.wwi keystone recompile, the #69 root-without--I contract, the
#70 aggregate-def .wwi prototypes, and the #95 spread-marker
round-trip. Every carrier assertion has a successor row; the C
cleanup-accounting ledgers collapse into testenv.clean.
