//ww:error "arr[i].field compound on float field"
// Lifted from test/wcc/949_idxfield_compound_run.c reject row "fld_he_float"
// (#33/rule-7): a compound assign on an indexed-element FLOAT field is unwired
// in both stages and MUST loud-fail, not silently fall through. The substring
// is the shared diagnostic body — byte-identical on both stages, pinned to
// "float field" so it cannot also match the str/slice/tagged rows (no
// file:line, no cstage "ww: " prefix — both differ cs vs ww).
