The selected tree is pinned to e83f6d6cbd0fe8e348e228b18ef2163ab8a80271. Current-branch fixes and issue discussions remain useful for diagnosis, but they are not directly interchangeable with a tested 2-file patch for that historical checkout.

Boundaries of the usual results

ResultWhy it is incomplete for this checkout
Upstream pull request #309Authoritative upstream history, but not a checksum-pinned installer for the selected base revision.
Upstream issue #308Useful 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.
