wwstage .len on a def-global array fell to the cgdot SB-fallback (w6l: undefined reference to 'len') — the #7 let-array arm gates on letvartnode (c.lets only), so def-globals (c.defs) missed it. Add a def .len-only arm in cgdot using the existing defvartnode (the def-side mirror of letvartnode), emitting the length immediate from the #11-stamped N_TARRAY length child. cstage cgen.c was already correct, so this is a wwstage-only source change: w6c unchanged, w6c_ww + wwdump regen'd (they embed the wcc cgen). .ptr (cstage itself buggy — emits LEAQ (BP), filed GAP-A.ptr) and .cap (wwstage silent garbage; arrays have no cap, filed GAP-A.cap) are NOT folded (rule-11, separate concerns). Pin: table-driven test/wcc/816_def_arr_len (def [3] + [_] inferred + 1-elem + u8 stride .len, both stages + byte-id), teeth-proven.
