The N_TTAGGED serializer emitted each variant via wwi_type but never re-emitted the `...` prefix for TK_ELLIPSIS spread variants, so an exported `(...inner | str)` round-tripped through .wwi as `(inner | str)`. The consumer's checker then could not flatten inner's members into the alias and variadic-assignability rejected bare members — under separate compilation this broke fmt/log/getopt. Re-emit `...` before the variant type, both stages; the producer stays purely syntactic (flatten/dedup remain the consumer's type-store job, per ref/hare/hare/unparse/type.ha:290-300). Gate: test/wcc/989_wwispread_sep.c — table-driven (2-arm + 3-arm spreads) x both stages, asserts the marker survives the .wwi, the consumer binds bare members under --sep (exit 0), and cs==ww .wwi byte-identity.
