cgassign's two element-store sites (N_DOT and N_INDEX index targets) fed the index node into indexvaluetnode to recover the element type. The tagged-store machinery reads tinfo directly post-#68, so both sites now read the checker- stamped element tinfo via lhs.type_: esz from .size (mirror #60), tagged gate via the shared istaggedtype/slotsize/cgwidentaggedstore path (all NAMED- peeling). cstage parity: cgen.c:3507-3523 (idx_eff(base->type)->sub->size). The new esz reads the element's natural .size, where the old elemsizeofc routed struct elements through slotsize -- so a padded-struct chained-index store (`[][]Point`) now matches cstage's ->size instead of diverging; that shape is untested (#7 indexbaseesz territory), so this is faithfulness, not a corpus change. With cgassign migrated, indexvaluetnode has zero external callers; dotfieldtnode's sole caller was indexvaluetnode; rhstargetname is self-recursive only -- all three retired (-132 LOC). This closes the A.6.3 AST-walker arc: the *node type-resolvers that existed because tinfo was lossy on nominal identity are gone, now that Phase-N (#63-#68) built the TY_NAMED layer and every consumer reads the stamped tinfo. make test 134/134, byte-id 950+990-997 hold.
