Continues the test-arch tower past Fam8-13. 11 module-level static-init / DATA-emit value drivers move from test/wcc/*_run.c into @test row- tables under test/lang/; every classification empirically re-probed at HEAD (refuting two stale worklist tags). - value rows -> test/lang/*_test.ww (11 files) - reject rows -> runww //ww:error carriers (3, dual-stage non-vacuous; 947 const-divzero confirmed a both-stage compile-reject, not run-exit) - 840_zeroinit, 944_array_zeroinit, 989_arrlit_tail_zero kept as byte-id .c pins (zero-over-dirtied-frame / DATAW-length is byte-id-blind to a runtime @test; #263), mutation-gated - repoint two stale comment refs to deleted test names (719, 989_structlocal_frame) Migrated static-init @test ride the cs==ww T2 byte-id gate, preserving DATA-emit byte-id. 2D global-struct array-field read (#137/#150) confirmed cs==ww + correct at HEAD. Coverage parity verified row-by-row; two-round reviewed. Floor ratchet follows.

// arr_u16_store_test — [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.
