Compact local KOMPAS-3D API retrieval core: bilingual USER2 V1, dense index, verified graph paths, lazy full-text GOST search, recipes, and compiler evidence for 19,331 API documents. Designed for dwnmf/kompas-guard-sdk; no HTTP service required.

Core is the default production profile. The SDK downloads this immutable snapshot once, verifies manifest.json SHA-256 hashes, and reuses the local Hugging Face cache. Measured Windows RSS after the first query: about 382 MB.

Our fine-tuned weights, indexes, graph projections, and bundled production artifacts are CC BY-NC 4.0: commercial use is prohibited without separate written permission. Upstream USER2-small components remain under Apache-2.0. See LICENSE.md and NOTICE.md.
