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.

// structlit_arrfield_test — struct array-field init + read (global let/def and
|
|
// local lit). Migrated from test/wcc/949_structlit_arrfield_run.c (#249). BUG B:
|
|
// reading a [4]u8 field of a module-global struct SEGFAULTed on wwstage; BUG A:
|
|
// a local struct-lit array field fell to the scalar tail and dropped every
|
|
// element but the first. Fix = cg_structlit_fill array arm + def_isstructdef
|
|
// LOAD widening (ADDQ $field_off). cstage build+run was T1; cs==ww .s byte-id
|
|
// rides T2 (test-lang-byteid). The def row has a [3]u8 pad ahead of encmap, so
|
|
// the read exercises a non-zero field offset (the base64 std_encoding shape).
