Immutable source snapshot

browser-local-v1 snapshot

Browser integration v1, derived from the validated desktop WebGPU prototype. FP32 export of checkpoint 6133648b2926b38542ee3ee1251a1ba111d61da9a8ea69d1c5f0559b09933643; model ONNX SHA-256 e16f6aab5bb02f8b90014f15b55f423d1ac59d6941c9e3bebb5e6bda557499a4. These are the exact integrated original frontend/policy/worker/runner files; third-party dependencies are separately licensed. ONNX Runtime Web 1.24.3 and chess.js 1.4.0. Website bundling changes paths and presentation but preserves model-scoring code. This source subset omits the exporter, which remains part of the recorded prototype validation, and is not a standalone build bundle. Device-dependent mate-helper budget may change overrides. No GPU memory or universal performance guarantee.
