## Title

    Diagnose with set equality and record-side membership before trusting either counts or graph

## Body

    Two structural checks decide which side is wrong, without any name matching: (1) compare the child's reverse-graph member slugs, in order, with the same-slug parent's; (2) for every member, read the member record's own area targets {kind, slug, city} and check whether any names the child. Equal member lists plus 0 records naming the child means the graph producer collapsed kind (slug-only key); counts of 0 are then consistent. Also treat a bounded reverse-graph sample (hasMore) as non-exhaustive, and never union event-venue places into an area's place list to 'fix' it.
