+# Interactive capability catalog
+
+Close gap analysis priority 13 (UC-RS-018 enhancement). Build a static,
+searchable catalog UI over exported registry data.
+
+## Add Catalog Site Generator
+
+```task
+id: REUSE-WP-0007-T01
+status: done
+priority: high
+state_hub_task_id: "84c56268-2e0b-42e6-b20e-6fbf059dcc20"
+```
+
+Extend `reuse-surface catalog` (or add `catalog site`) to emit
+`docs/catalog/registry.json` alongside existing MD/HTML outputs.
+
+## Build Searchable Catalog UI
+
+```task
+id: REUSE-WP-0007-T02
+status: done
+priority: high
+state_hub_task_id: "d587bc50-adb2-424a-a9d3-600a2ec5ba9b"
+```
+
+Create `docs/catalog/search.html` with client-side filter by name, summary, tags,
+vector, and consumption mode. No backend required.
+
+## Wire Catalog Into CI And Docs
+
+```task
+id: REUSE-WP-0007-T03

+priority: medium
+state_hub_task_id: "eca7438c-3c2f-4027-9b40-67df5f17aca7"

+Update CI to regenerate catalog artifacts, document browsing in
+`docs/CapabilityRegistryConcept.md` and `SCOPE.md`.
