# description
Directory of active ADN rooftops with public metadata and per-rooftop manifest URLs. Supports offset paging through a reachable window of offset 10000 + limit 500; active rooftops approaching that window are a contract-revision trigger. Paging is NOT snapshot-isolated: rooftop activation, deactivation, or renaming between page requests can shift offsets and silently duplicate or omit rows — compare total across pages and restart the traversal if it changes. A membership change that leaves total unchanged is an accepted, undetectable residual (matching the network.search admin-reconfiguration residual).
