Official build/source correspondence
------------------------------------
- lxml source: lxml-6.1.3.tar.gz, SHA-256 45222D94DDD511536F3B2F7D9DEAE3B2339B4CE0F075F1CA25703B07CAD9DD21.
- The lxml-6.1.3 release workflow builds Windows wheels through buildlibxml.py and the official lxml/libxml2-win-binaries release feed.
- At the 2026-09-02 lxml release date, the latest dependency release selected by that script was lxml/libxml2-win-binaries tag 2026.05.17.
- The wheel's compiled/runtime libxml2 2.11.9 and libxslt 1.1.45 values match that release's win64 assets.
- That release identifies iconv-1.17.1.win64.zip, size 992481 bytes, SHA-256 090225898FC0B37FE1F0D3ECC3938C926DE77CD7F8C3636A5C9712B61E7AF849.
- The dependency repository tag pins libiconv submodule commit 880a1fa8b5581e37e136a7b051947d3ea39097b6 and includes build.ps1 plus libiconv.patch.
- The retained winlibs libiconv commit archive contains the full upstream-derived source tree, LGPL-2.1 text, MSVC14/15/16/17 project files, patches and build inputs.

This establishes corresponding source availability and the official build path. It does not claim a locally reproduced bit-for-bit rebuild of the wheel. Exact bit-for-bit rebuild provenance is not treated as an additional redistribution requirement.
