depot_tools commit d4e95894 changed the fetch wrapper to run the hermetic Python from depot_tools' own python-bin directory, which only exists after the bootstrap that fetch used to perform itself. A fresh clone followed by fetch now fails with "python3_bin_reldir.txt not found", the checkout never happens, and the build fails later on missing objects. Every build without a cached WebRTC library on Linux and macOS has failed this way since 2026-09-08. Running ensure_bootstrap right after the clone restores the previous behavior. The Windows wrapper still bootstraps on its own.
