      "deviation": "D-1 cache read cannot be keyed by ClusterId at the boot seam (unkeyed newest-pointer read instead); D-3 a third LiteDB test file must be deleted; D-5 WebApplicationFactory<Program> is deliberately unused in this repo (use TwoNodeClusterHarness); D-6 driver-only nodes have no ASPNETCORE_URLS so the Kestrel re-bind fallback is wrong.
