• 🔴 (10:06) User stated the cache-directory resolution/purge path in packages/core/src/embedding-worker.ts is never called for vendored binaries; it resolves downloaded models to <cacheDir>/<modelId>/.
• 🔴 (10:06) User stated shorter texts can never exceed the model limit because the conservative estimate is approximately ~1 char/token; token counting excludes [CLS] and [SEP] special tokens so ids.length reflects pure content.
• 🔴 (10:06) User stated the embedding runtime switched to native because native execution scales with cores; the corresponding WASM threading configuration is therefore a no-op on the native path.
• 🔴 (10:06) User stated transformers.js uses native ONNX Runtime because it is 2.7–4.1× faster than WASM, referencing #999.
• 🔴 (10:06) Current packages/core/src/embedding-worker.ts throws embedding-worker must be run as a worker thread when not executed in a worker thread.
