local_zeroinit_test.ww takes the 840/944 zero-init seam (dirty-frame
prime and probe share one @test because the runtime forks per test);
alias_cgen_b6, alloc_nested_field, array_static_init, and
strarray_static gain the rows their retired wrappers held; the
remaining files re-point reject-row citations at the r788_* and
stage-matrix fixtures.
