Rule-engine-based list endpoint — an alternative to the simple filter.* query params on the plain list endpoint, for building complex AND/OR filter conditions. Unlike other modules, invalid sort_by/sort values are not rejected — they silently fall back to the defaults (created_at / DESC) instead of returning a 400. filter_rules is only honored when the request opts into the rule-engine listing mode; without filter_rules, the endpoint falls back to legacy filter.job_uid / filter.project_uid / filter.user_uid query-style params on the same body.
