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.

// [N]u16/[N]i16 array-literal init stores MOVW per slot.
|
|
// Migrated from test/wcc/914_arr_u16_store_run.c. Pre-fix a [4]u16 init emitted
|
|
// overlapping MOVQ stores (accident-corrected for some values); the fix dispatches
|
|
// a proper MOVW per 2-byte slot (op chosen by esz, not signedness). cstage
|
|
// build+run was T1; cs==ww .s byte-id rides T2 (test-lang-byteid). The full_init
|
|
// row asserts each element to catch any value drift; the [4]u8 control pins the
|
|
// MOVB path is unchanged; i16_signed pins the dispatch is not signedness-gated.
