Single program exercising recursion + stratified negation +
aggregation + comparison composed end-to-end via dl-eval. Confirms
the full pipeline (parser → safety → stratifier → semi-naive +
aggregate post-pass → query) on a non-trivial program.

  edge graph + banned set →
    reach transitive closure →
    safe (reach minus banned) →
    reach_count via count aggregation grouped by source →
    popular = reach_count >= 2

- 2026-05-08 — Comprehensive integration test in api suite: a
single program exercising recursion (`reach` transitive closure)
+ stratified negation (`safe X Y :- reach X Y, not banned Y`) +
aggregation (`reach_count` via count) + comparison (`>= N 2`)
composed end-to-end via `dl-eval source query-source`. Confirms
the full pipeline (parser → safety → stratifier → semi-naive +
aggregate post-pass → query) on a non-trivial program.
- 2026-05-08 — Bug fix: aggregates work as top-level query goals.
`dl-match-lit` (the naive matcher used by `dl-find-bindings`) was
missing the `dl-aggregate?` dispatch — it was only present in
