-# Doppel embeddings companion
+# Doppel runtime artifact
 
-This repository is Doppel's distribution channel for an app-specific Core ML
-conversion of
-[`jinaai/jina-embeddings-v2-small-en`](https://huggingface.co/jinaai/jina-embeddings-v2-small-en).
-It supports Doppel's private, on-device search index.
+This repository contains a versioned runtime artifact consumed by compatible
+Doppel releases.
 
-## Intended use
+It is not a standalone model, SDK, or supported public API. Its format,
+compatibility contract, and behavior are private implementation details and
+may change without notice. No external loading, conversion, integration, or
+evaluation guidance is provided.
 
-These artifacts are intended to be downloaded, verified, and invoked by
-Doppel on Apple-silicon Macs running macOS 15 or later. Indexed content and
-generated embeddings remain on the user's device.
+The repository contains no customer data.
 
-This is not a standalone embedding distribution or a supported developer API.
-The repository does not include Doppel's text preparation, pooling,
-normalization, indexing, retrieval, or compatibility logic. Results produced
-outside that contract are not supported or comparable to Doppel search. For
-general-purpose use, start with the upstream model.

-## Artifact and integrity notes
-
-The compiled Core ML components are modified from the upstream checkpoint for
-Doppel's bounded runtime shapes. `jina_coreml_manifest.json` is the
-authoritative artifact inventory and records the integrity hashes checked by
-the app.
-
-The repository contains no user documents, embeddings, search indexes,
-queries, prompts, telemetry, or other customer data.
-
-## Limitations
-
-Embedding similarity is not a factuality, authorization, or safety signal.
-Retrieval quality varies with language, document structure, terminology, and
-the surrounding search pipeline.
