Both the merge-parent and the PR-creation-time tip carry identical content for the 3 PR-touched non-NEWS files (Lib/tomllib/__init__.py and Lib/tomllib/_parser.py do not exist at either; Python/stdlib_module_names.h has the same blob hash); the patches apply cleanly at either. Using merge_parent for consistency with prior CPython instances and to avoid carrying drift commits in the base tree. Same pattern as PEP-617 / PEP-634 / PEP-654 / PEP-669.",
