Experimental six-module model assets (Float16 weights, 567befb)

Experimental converted model assets for Unity Inference Engine / Sentis 2.6.1.

Upstream: google/embeddinggemma-2 at the fixed revision, by Google DeepMind, Apache-2.0. Retain LICENSE.txt, NOTICE.txt and MODIFICATIONS.txt with these files.

Precision: float16. The bundle contains text, image-square, image-landscape, image-portrait, audio-1119 and audio-839; 820 content-addressed objects.

Descriptor SHA256: 8a6a90c5f656a00b024553a0412e5c4d32b4d2c9c7c5b3a0c2c146f557b4e27e.

Composition source: 567befbd64287a706edaac59c978927e0277188a. Component producer IDs and all object hashes are in the descriptor/inventory. Model buffers remain separate from Git and the UPM package.

Windows component GPU qualification is recorded in the project. Public empty-cache acquisition and the final integrated consumer/platform gates are still being completed. This model preview is separate from the formal SDK release.

Use the acquisition tool at fixed source 8649c9435f502738bc9c89a27c9a09483a7719eb (reviewed integration candidate). It is a development candidate while final SDK release gates remain open. In a new checkout, run:

git clone --no-checkout https://github.com/ayutaz/unity-embeddinggemma-2.git EmbeddingGemmaTools
git -C EmbeddingGemmaTools checkout --detach 8649c9435f502738bc9c89a27c9a09483a7719eb
Set-Location EmbeddingGemmaTools/tools

Download and retain the three accompanying text files, then run the pinned-descriptor acquisition command:
