cstage rejects `add(1,2,3)` and `add(4)` (too many / not enough arguments); wwstage ran no count check at this seam, so both built -- a stray arg pushed silently, a missing one read garbage (cs-reject/ww-accept build-verdict divergence). Surplus errs when params exhaust with args left; missing errs on a leftover regular param (a leftover TK_ELLIPSIS or FFI "..." is a legal zero-arg variadic tail). fn-VALUE callees still bail at decl==nil -- their whole typecheck, arity included, stays task #51.
