Compatibility record

This public record describes the supported beta boundary without publishing an identifying host fingerprint.

Toolchain

Component Reviewed version
Node.js 24.19.0 for the release build; 22+ supported for development
pnpm 10.15.0
TypeScript 5.9.3
Vite 7.3.6
Playwright 1.63.0
WebLLM 0.2.85
Transformers.js 4.3.0
Extension manifest MV3, minimum Chrome 116

CI builds and browser tests run on GitHub-hosted Linux with Playwright Chromium. The trusted real-model beta run used headed Chrome 153 on Windows 11, Transformers.js on WASM, and WebLLM on a discrete NVIDIA WebGPU adapter. Exact personal-host specifications are deliberately omitted from the public record.

Generation model

  • Runtime registry ID: SmolLM2-360M-Instruct-q4f16_1-MLC.
  • MLC model revision: 3a622fd89e0216e8bb10c410c007c786baa8a033.
  • Base model: HuggingFaceTB/SmolLM2-360M-Instruct.
  • Base revision: a10cc1512eabd3dde888204e902eca88bddb4951.
  • Base license metadata: Apache-2.0.
  • Packaged model-library upstream revision: 025bcaf3780fa8254f5e5efd3bfea0a5397248f4.
  • Packaged model-library SHA-256: 5c20098605780550c40e9c64d288dd6e369707a08d4133037156019b064ad41b.
  • Reviewed quantized weight shards: 203,614,080 bytes, excluding tokenizer, configuration, and browser overhead.

The fixed beta run proved real adapter load, streaming, exact-marker output, structured schema validity, in-flight cancellation, and fresh-worker recovery. Its small semantic probe scored 0/2 and missing-fact abstention scored 0/1. Generation is therefore experimental.

Embedding model

  • Model: Xenova/all-MiniLM-L6-v2.
  • Revision: 751bff37182d3f1213fa05d7196b954e230abad9.
  • License metadata: Apache-2.0.
  • Reviewed quantized ONNX artifact: 22,972,370 bytes.
  • Quantized ONNX SHA-256: afdb6f1a0e45b715d0bb9b11772f032c399babd23bfc31fed1c170afc848bdb1.

The fixed beta run produced valid 384-dimensional vectors and selected the expected source for 3/3 synthetic retrieval probes.

Integrity boundary

The generation model-library WASM is packaged and hash checked. Model weights, tokenizer files, configuration, and compiled browser caches remain runtime-managed data downloaded after consent. The registry pins their reviewed identities and known bytes, but the adapters do not claim an independent byte-for-byte audit of every remote cache entry.

Model discovery, successful loading, correct schema, semantic correctness, source support, and safe authority are separate checks.
