Automated Validation Coverage

The 3.12.0 validation matrix includes build-zlib-bcc32, build-zlib-bcc64x, build-zlib-vc64, build-jpeg-bcc32, and build-jpeg-vc64, each completing with zero failed objects. Library package builds were also verified with build-Win32-Lib.cmd 37.0 and build-Win64-Lib.cmd 37.0.

The Delphi DUnitX suites passed 132 of 132 tests on Win32 and 132 of 132 tests on Win64. Covered areas include compression round trips, HelloWorld /FlateDecode output, JPEG and PNG rendering, image import and export, fonts, forms, encryption, decryption, signing, printing, Unicode helpers, buffers, canvas drawing, pages, tables, and document workflows.

The C++Builder Win64x GoogleTest suite passed 56 of 56 tests. It covers demo-derived workflows plus zlib-ng large-payload round trips, image handling, render output, encryption, signing, printing, and HelloWorld compressed-output checks, which validates the bcc64x zlib-ng object set through the C++Builder ABI.

The reference guide itself was exported to PDF with LibreOffice and the first page was rendered with Poppler, providing a structural check after the help text updates.

Readme.html provides the short product overview for evaluators and should be kept aligned with ChangeLog.txt, TechnicalNotes.txt, and this reference guide when backend behavior or validation coverage changes.
