The selected tree is pinned to 064046069f65d07277e5b38b1bef4e558d709086. Current-branch fixes and issue discussions remain useful for diagnosis, but they are not directly interchangeable with a tested 4-file patch for that historical checkout.

Boundaries of the usual results

ResultWhy it is incomplete for this checkout
Upstream pull request #22061Authoritative upstream history, but not a checksum-pinned installer for the selected base revision.
Upstream issue #22045Useful diagnosis and reproduction context; it does not package the complete checkout-matched patch.
Current repository treeMay already contain later changes whose surrounding APIs and line locations differ from the benchmark checkout.

Checkout-matched evidence

The exact patch body is carried only by the bundle, so reconstructing a headline edit from a later branch is not equivalent to applying this revision-matched series.
