Three real-engine throughput loops (thumbnail pipeline, full-res fill behind the proxy, playback window supply) failed on machine slowness: their pass/fail was a wall-clock Instant deadline, so a loaded machine broke them for speed, not for a broken pipeline. Each loop now counts engine pumps — machine-speed independent — and asserts the condition within a bounded number of pumps. The two single-frame worker channel receives keep a generous 60 s recv_timeout (a one-shot bounded operation, not a throughput loop). oak-cli: the integration fixtures moved with the app crate during the workspace restructure; point the fixture helpers at ../oak-app/tests instead of the (now empty) repo-root tests/.
