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.
The unowned remainder is the four run-stderr assertions — msg content
for fail_msg/abort_msg, MANDATORY EMPTINESS for fail_nomsg/abort_bare
(rt_abort(NULL,0) writes nothing) — which the fixture protocol cannot
see (run exit only). The rows build the r957_* fixture sources in
place via the cstage driver; byte-id extends the lowering to wwstage
(the carrier's own argument). Owned legs cited, not duplicated: all
eight exit rows by the r957_assert_*/r957_abort_* fixtures, the
checker rejects by r957_assert_reject_*, byte-id by the
test-data-byteid blanket.
Only the ast_proof leg was unowned: wwdump -a / wwdump_ww -a dump
byte-id plus the ordered dot-over-structlit-over-tname node shape for
a trailing op on a qualified struct literal (inexpressible as a
runtime scenario while the #77 literal-temporary cgen gap holds; the
multilevel row pins the source-order a.b.C tname flatten). The three
build/run scenarios are owned by the r84_qualstruct_* fixtures plus
the test-data-byteid blanket — their vestigial want_exit fields were
already dead in the carrier.
954_tuprecv_run, 956_tuprecv_f64_run and 956_modqualdestr_run shared
one retained dimension: w6c_ww compiles the destructure shape cleanly
AND emits no asserttyped stderr diagnostic (#121 A-narrow / #6a-A
stamp nets) — a channel neither test/lang nor the fixture protocol
has. All 11 rows fold into one observer with the drew-C4 non-vacuity
self-check on the shared predicate. Owned legs cited, not duplicated:
value rows + byte-id ride test/lang/tuprecv_test.ww,
test/lang/tuprecv_f64_test.ww and the test-lang-byteid blanket; the
modqual values + byte-id ride the r956_modqual_* fixtures and
test-data-byteid — those four rows compile the fixture files in place
so probe and fixture cannot drift. Bundled: one file, one concern
(the wwstage stamp-absence dimension).
826_alias_tuple_coerce, 944_alias_accept_run and
944_variant_chain_b95_run all reduced to the same irreducible shape: a
LIVE per-stage asymmetry (probed at HEAD) no symmetric fixture or
@test can host. Ported under the DIVERGE discipline — both sides
asserted loud (826 neg_0: cstage "not assignable to declared pair"
vs wwstage over-accept; #96: cstage runs vs w6c_ww "unsupported
address-of shape"; #277: cstage runs vs ww_ww "deferred #277"), so
a fix on either side fails the row and demands graduation. Owned legs
cited, not duplicated: r826_alias_tuple_* byte rows ride
test-data-byteid, 826's neg_1 went symmetric at HEAD and moves to a
//ww:error fixture per the audit split, the 944 value/reject corpora
live in test/lang/{alias_accept,variant_chain_b95}_test.ww and the
alias_*/vchain_* fixtures. Bundled: one file, one concern (held
divergence pins).
Both carriers were already slim: the r76_def_widen_* byte-id legs are
owned by the test-data-byteid blanket, 783's positive byte rows by the
r78_amp_fn_assign_* fixtures plus that same blanket, and its symmetric
non-tagged rejects by the corpus //ww:error fixtures. The unowned
remainder is three cstage-only loud-rejects (the 760 narrowing def-ref
and 783's two tagged-slot rows); the wwstage over-accepts (no def-init
assignability check; #214 void-variant leniency) are documented at the
site per the residual audit, never asserted as desired — the rows
graduate to //ww:error fixtures when the wwstage side tightens.
Bundled: one file, one concern (cstage-reject pins awaiting wwstage
graduation).
wwiroundtrip pins the @packed re-emit through a real -I tree on both
driver stages (importer-side layout exit 91), strengthened with the
`struct @packed {` needle in the retained sepwork pk2.wwi (a
single-file two-package form emits no .wwi, so the tree is
irreducible). identityreject pins the stage asymmetry as a DIVERGE
row: cstage rejects with "not assignable" (packed is type identity,
harec types.c:621), wwstage builds+runs through the documented
#224/#10 nominal-lossy leniency; a wwstage tighten fails the row and
demands graduation to a //ww:error fixture. The 15 layout/runtime
value rows are fixture-shaped and move to the declarative corpus per
the residual audit port split.
test/misc hosts the residual mixed-shape observers (divergence pins,
stamp/stderr probes, .wwi trees) on testenv, wired into test-compiler
beside the sep/xmod/asm families; its rule declares both full
per-stage toolchains plus the wwdump twins for the coming files.
The 689 port keeps the both-driver run-exit-6 backstop and the
per-stage absolute DATAW row count (linker dedup and byte-id sweeps
are both blind to a symmetric double-emit).
