INNOS GIF 1.0.5 corresponding engine source and build materials

FFmpeg 9.0.1 official source (unmodified), zlib 1.3.2 source (unmodified).
FFmpeg: LGPL 2.1 or later. zlib: zlib license. Complete licenses are in the sources.
The application invokes ffmpeg.exe separately and does not link to its libraries.
The engine is a static LGPL executable; the entire engine source is provided.
No GPL/nonfree/version3 multimedia options or external codec libraries are enabled.
MinGW/GCC runtime notices and GCC Runtime Library Exception apply as documented.

Ubuntu 22.04 build prerequisites:
apt-get install gcc-mingw-w64-x86-64-win32 nasm pkg-config make xz-utils
Exact package versions: verification/toolchain.txt
Run: bash build-from-bundled.sh /path/with/free/space
Expected output: /path/with/free/space/output/ffmpeg.exe
No media source downloads are required by build-from-bundled.sh.
FFmpeg official release signature and the pinned signing key fingerprint are
recorded in verification/signature.txt. Source and shipped executable SHA-256
values are included. changes.diff is empty: no upstream source edits were made.
Paths and PE build timestamps may differ on rebuilding; byte-identical output
is not promised. The shipped binary was built with original-build.sh.

Supported tested workflow: common SDR video to GIF and JPG/PNG/BMP photo sequence.
AV1 is not enabled. File extension alone does not guarantee codec support.
Source access, replacement and modification rights are not restricted by INNOS.
This is a license-compliance record, not a patent clearance opinion.
