Every section banner dies (103 -> 0) across test/lang, the observer
suites, the C carriers, and the five comment-heavy corpus fixtures;
banner provenance (#N cites, carrier numbers, repair-cluster labels)
folded into headers or adjacent WHY comments. Narration deleted; row
provenance, ref cites, divergence pins, and layout contracts kept
(fwd-ref decl-order guards and bootstrap-gate corpus rationale
restored where the sweep over-cut). Comment-only proven: all 3742
wwbuild workdir .s byte-identical before/after; test-commit and
test-byteid (161 lang + 1399 data, 0 pinned-divergent) green.
Go compiles only _test.go files as tests; discovery now keys on the
_test.ww suffix alone. The line-leading-@test compatibility allowance
(noncanonical filenames admitted as test sources) is removed from both
driver stages and the coordinator. An @test declaration outside a
*_test.ww file is rejected loudly ("@test declaration outside
*_test.ww", wording byte-identical cs/ww) instead of silently running
under compose or silently dropping in a non-T build (#6). Tree audit
found zero real carriers; the two allowance fixtures flip canonical
(dep_test.ww, widget_test.ww). New pins: direnum attest-noncanon
reject row (both-stage stderr parity) and the coordinator
noncanonical_attest_rejected package row.
m3sep_test.ww drives the raw w6c/w6a/w6l toolchains (+_ww twins) over
hand-composed //ww:module units splicing produced .wwi bytes: the
bodies==.wwi keystone on both stages per package (mid/root/smid) with
determinism, rule-10 and the value-global DATA guard; the end-to-end
i32 chain (exit 59) with final-exe byte-id; and the #49 str-label /
#53 export-leaf link legs (exits 160/140) with their .s needle
proofs. Each @test re-produces its .wwi cold instead of sharing the
carrier's single scratch dir (same claims, sharper isolation).
septest_test.ww keeps all five rows (pass/fail run-exits, the
userman + badsig @test rejects, the collide_run user-fn-run coexist)
plus the full-sepwork .s/.wwi byte-id sweep and the -T synth
TEXT-main / CALL-test.run presence needles, both driver stages. The
pass/fail run-exit rows overlap package_test ownership but stay:
retiring them would drop audit-listed assertions from this gate. The
attest_* data fixtures remain in test/wcc/data (also consumed by the
911_attest_* carriers).
sepscratch_test.ww pins the #59 build_one_sep scratch ownership on
both driver stages: build -o keeps <stem>.sepwork, `run` leaves no
/tmp/ww_run_<pid> root, and a foreign pre-existing .sepwork is
refused with exit exactly 1, sentinel intact. The C fork/execl pid
capture becomes `sh -c 'echo $$ ...; exec <drv> run ...'` -- exec
keeps the shell's pid and passes the full driver path as argv[0].
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.
