def C:[N]str; C[i] was loud (undefined main.C) both stages. Three folded fixes, one commit (splitting would ship a bisect point where wwstage silently returns an element address instead of .len): P0: the str-array static-init emitter dropped its vestigial directive =="DATAW" gate so a def table rides the same DATAW-header + DATAR-reloc path as let. A def str/slice table lives in DATAW by w6a's A_DATAR-holder constraint -- placement only; def immutability stays checker-enforced. P1: let_pre_intern / letpreintern walked N_LET only, so a def str-array's element string-literals were never interned (dangling _S_n). Extracted a pre_intern_strarray SSoT helper, called for a def str-array arm too, both stages. Scoped to str fixed arrays; def []T / def [N][]T stay loud (#270). P2: wwstage cgenexpr lacked a defvartnode fallback in the indexed-element classify, so a def str-array element load returned the element address instead of the slice header -- a silent miscompile. One line, aligning wwstage up to cstage (which was correct). C[1].len now = 3 both stages, byte-identical. byte-id 990-997 8/8; w6c/w6c_ww move. test/wcc/819 table-driven. The def-global scalar str index sibling (def S:str; S[0]) stays task #14.
