multilingual-e5-small-int8 for Manticore

This repository is the immutable ONNX INT8 bundle used by ZimaOS Photos with Manticore automatic embeddings. The root model.onnx is copied from Xenova/multilingual-e5-small at revision 761b726dd34fb83930e26aab4e9ac3899aa1fa78, artifact onnx/model_int8.onnx.

The embedding contract is fixed:

• output dimension: 384;
• query text prefix: query: ;
• indexed caption prefix: passage: ;
• pooling: attention-mask mean pooling followed by L2 normalization;
• maximum sequence length: 512 tokens.

ZimaOS Photos stores bilingual VLM captions and detailed summaries as passages. Manticore downloads config.json, tokenizer.json, and the single root model.onnx automatically. No safetensors, GGUF, or alternate ONNX weights are published in this repository.

See PROVENANCE.json, 384D-prefix-fidelity-report.json, and SHA256SUMS for the pinned sources and validation results.
