 ### Fixes
 
+- **Restore default-on library-load telemetry**: The lightweight library-load ping once again runs by default when `unstructured` is imported. Set either `DO_NOT_TRACK` or `SCARF_NO_ANALYTICS` to any non-empty value (after trimming whitespace) before import to disable it; empty and whitespace-only values retain the default behavior. This removes the `UNSTRUCTURED_TELEMETRY_ENABLED` explicit opt-in gate introduced by #4281 while preserving the existing endpoint and payload. The best-effort `nvidia-smi` GPU probe now has a one-second timeout, and GPU-probe and request failures remain non-fatal.
+
 - **Stop the `GLOBAL_WORKING_DIR` tests from disturbing other pytest-xdist workers**: test-only change, no library behavior changes. The two tests exercising `GLOBAL_WORKING_DIR_ENABLED` now redirect the working dir to a private `tmp_path` and restore `tempfile.tempdir` unconditionally, rather than moving the shared pgid-keyed directory aside mid-run and leaving the worker's `tempfile.tempdir` pointed at it. That shared path made `test_dockerfile` fail intermittently, with an unrelated test dying inside `tempfile`.

-Telemetry is **off by default**. To opt in, set `UNSTRUCTURED_TELEMETRY_ENABLED=true` (or `=1`) before importing `unstructured`. To opt out, set `DO_NOT_TRACK` or `SCARF_NO_ANALYTICS` to any non-empty value (e.g. `true`, `1`, `yes`, `false`, `0`—any non-empty string opts out); opt-out takes precedence. Unset the variable or leave it empty if you do not want to opt out. See our [Privacy Policy](https://unstructured.io/privacy-policy).
+Unstructured sends a lightweight library-load analytics ping by default when it is imported. To opt out before importing `unstructured`, set either `DO_NOT_TRACK` or `SCARF_NO_ANALYTICS` to any non-empty value after trimming whitespace (for example, `true`, `1`, `yes`, `false`, or `0`); either variable disables the ping. Unset the variables or leave them empty or whitespace-only to retain the default behavior. See our [Privacy Policy](https://unstructured.io/privacy-policy).
