/* * 944_alias_emit_b7_run — #5 alias arc B7 (finale): the four cgen.c * static-DATA emitter ELEM-type chases. All four sites already chased * the OUTER type; the residual single peel was on the ELEMENT type * (u->sub), so a 2-level-elem-alias global missed the TY_STRUCT / * TY_STR / TY_TAGGED kind tests and fell off the foldable-literal * path. cs-only: every graduation is a cs-side flip onto ww's * already-correct emit (align cs UP); _ww binaries bit-identical * across the commit (comment-only ww annotation bytes are * codegen-inert). * * Sites (numbering at 05f7af7): emit_array_lit_bytes:14356 (struct * arm + raw-bytes path), emit_strarray_data:14574 (str DATAW+DATAR * rows), emit_slice_data:14788 (3-way slice-of-{str,slice,tagged} * fatal), let_pre_intern:15088 (the :14574 row's label-order leg — * MUST chase in the same commit or _S_ labels intern in emit order, * not decl order; strarr_2lvl's byte-id IS the coupling proof). * * Row sources: ken's B7 first-position oracle (/tmp/ken_b5/src/kb7_*, * .ai/ken-b7-oracle.md, matrix at 05f7af7) + impl pre-state probes. * NOTE: `type el = el0` where el0 is itself a type decl is ALREADY two * NAMED layers (NAMED(el)→NAMED(el0)→struct), so the "_1lvl" struct * spelling graduates with the 2-level rows; only a direct alias of a * primitive (type ms = str) is a true single layer. * * row | shape | cs/ww * -------------------+--------------------------------------+------ * sarr_2lvl | kb7_sarr [2]el 2-lvl alias struct | * | elem: cs emitted NO DATA (eu peel | * | missed TY_STRUCT → return 0 → caller | * | skipped the def) → link-loud.
