This\nconfirms AND semantics for comma-joined predicates on one `filter=` parameter,\nwhich is how an agent must express a closed date range on this API (there is no\nseparate `between` operator) — get this wrong (assume OR, or assume you need two\nseparate `filter=` query keys with the same name) and you either get the whole\ntable or a silently-dropped second predicate.
