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.

// Project #242: a mixed-scalar tuple wrapped in a tagged
|
|
// union must construct, match-bind, and destructure identically in both stages
|
|
// and round-trip every element. Migrated from test/wcc/940_tuple_in_union_run.c
|
|
// (K_RUN value rows). Three silent gate-blind cs!=ww divergences were met:
|
|
// cstage construction zeroed the whole value instead of packing the tuple
|
|
// variant; wwstage's checker left un-annotated destructure binders untyped for
|
|
// a non-call rhs; both stages destructured a tuple ident off a stale register
|
|
// cursor. The @test fns pin the runtime element values at variant 0 and at a
|
|
// non-zero variant index; T2 byte-id keeps cs==ww (rule 10). The K_BUILDERR
|
|
// bare-literal-element loud-stop row lives at test/wcc/data/tupunion_bool_literal/.
