• 🔴 (13:29) User added isNativeOrtLoadError coverage in packages/core/test/embedding-worker-types.test.ts for native ONNX Runtime loader failures including Error [ERR_DLOPEN_FAILED]: onnxruntime_binding.node: invalid ELF header, onnxruntime_binding.node: file too short, libonnxruntime.so.1: cannot open shared object file, and onnxruntime_binding.node: undefined symbol: OrtGetApiBase.
• 🔴 (13:29) User specified that resolveNativeOrtBindingPath returns null and never throws when native packages are absent.
• 🔴 (13:29) User added resolver-fixture and mutation tests for native ORT package validation, including Linux runtime resolution and published-package mutation cases.
• 🔴 (13:29) User specified that native ORT resolution never resolves an undeclared ancestor workspace package.
• 🔴 (13:29) User documented nativeIntraOpThreads behavior: it leaves ORT’s default untouched on unconstrained hosts, returning undefined for (available, logical) values (4, 4), (8, 8), and (1, 1).
• 🔴 (13:29) User specified that nativeIntraOpThreads never raises threads: nativeIntraOpThreads(8, 4) returns undefined, defensively handling the case where available parallelism exceeds logical CPUs.
• 🔴 (13:29) User stated availableParallelism should never exceed cpus().length; if it does, ORT must not be pushed above its physical-core default because that causes an RSS regression on hyper-threaded hosts.
• 🔴 (13:29) User added gateway bundle regression coverage that rejects a malformed native addon before loading the WASM fallback, with worker initialization/message handling and a 10_000 timeout.
• 🔴 (13:30) User showed packages/gateway/dist containing exactly 11 entries: bin.cjs, embedding-worker.cjs, embedding-worker.js, index.bun.js, index.cjs, index.cjs.map, index.d.cts, ort-wasm-simd-threaded.mjs, ort-wasm-simd-threaded.wasm, vector-worker.cjs, and vector-worker.js.
