int-mask<1, 2, 4>int-mask<1, 2, 4> describes every bitwise-or combination of the flags
(0..7), a refinement of int, so a @return int-mask<...> value always
satisfies a native int parameter. Analyzers that model the mask reject a
value that is not a valid combination; others fall back to int.

Notes: `int-mask<...>` has no entry in `lower_generic`'s vocabulary table (steins-contract/src/lib.rs), so it lowers through the catch-all to `ContractTy::Class("int-mask")` rather than any int refinement, and the bit-set membership is never checked. |
