  "message": "fix: avoid stage1 bootstrap stdlib shadowing (#3854)\n\nThe stage 1 system-python bootstrap imports standard-library modules\nbefore it\nre-execs into the configured runtime. If the target output directory\ncontains\nfiles named like standard-library modules, such as `shutil.py` or\n`types.py`,\nthe bootstrap can import those files instead and fail before user code\nstarts.\n\nThis change removes Python\u0027s unsafe script-directory prepend before\nthose early\nimports, while preserving `sys.path[0]` when Python has already\nsuppressed that\nprepend through `-P`/`PYTHONSAFEPATH` or isolated mode. Stage 2 now uses\nthe same\nisolated-mode guard when removing or recreating the main-directory path.\n\nIt also pins the Windows venv entry point template to LF line endings so\nthe\ncompile-pip CI dirty-worktree check is stable across checkout settings.\n\nBefore this change, a generated target output could shadow bootstrap\nstdlib\nimports, and isolated-mode runs on older Python versions could lose a\nrequired\nstdlib path.\n\nAfter this change, bootstrap stdlib imports resolve from the\ninterpreter\u0027s\nstandard library, isolated mode preserves the interpreter-provided path,\nand the\nline-ending-sensitive CI check stays clean.\n\nTests:\n\n```shell\nbazel test --config\u003dfast-tests \\\n  //tests/bootstrap_impls:stdlib_shadowing_system_python_test\n\nbazel test --config\u003dfast-tests \\\n  //tests/bootstrap_impls:stdlib_shadowing_system_python_test \\\n  //tests/bootstrap_impls:interpreter_args_test \\\n  //tests/bootstrap_impls:sys_path_order_bootstrap_script_test\n```\n\n(cherry picked from commit fbb2ccf4ca4ac5d43f2e4181469b04dc14cfb092)\n",
