`count(N, Y, p(X))` silently returned `N = 1` because `Y` was never bound by the goal — every match contributed the same unbound symbol which dl-val-member? deduped to a single entry. Similarly: sum(S, Y, p(X)) => raises "expected number, got symbol" findall(L, Y, p(X)) => L = (Y) (a list containing the unbound symbol) count(N, Y, p(X)) => N = 1 (silent garbage) Added a third validator in dl-eval-aggregate: the agg-var must syntactically appear among the goal's variables. Error names the variable and the goal and explains why the result would be meaningless. 1 new test; conformance 263/263. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
