+### Create Docker/Podman Nextcloud Integration Test Harness  
+**ID:** NUT-024  
+**Status:** Triage  
+**Type:** Foundation  
+
+**Description:**  
+Create a containerized integration test harness using Docker or Podman to spin up an ephemeral, fresh Nextcloud instance, seed an admin test account and credentials, and execute end-to-end integration tests for the CLI against real WebDAV and OCS sharing endpoints.
+
+**Requirements:**  
+- [ ] Provide setup script (`scripts/test-server-up.sh`) using Docker/Podman compose to launch and initialize a fresh Nextcloud container  
+- [ ] Automatically configure admin user credentials, disable password expiration, and establish app password / token  
+- [ ] Provide teardown script (`scripts/test-server-down.sh`) for clean container and volume disposal  
+- [ ] Implement Rust integration test suite (`tests/cli_integration.rs` or `cli/tests/`) running real CLI uploads, folder creations, stdin streams, and public share link verifications  
+- [ ] Support automated CI/CD execution of the integration harness
