Analyst notes
Every signal the ML model flagged has a clear, benign explanation rooted in the extension's stated purpose. The `wasm-unsafe-eval` CSP is required to run ONNX Runtime (WebAssembly) for on-device htdemucs audio separation; `document_start` execution of ` ` is necessary to install MediaSource Extensions hooks (`SourceBuffer.prototype.appendBuffer`) before YouTube's player initializes; all `innerHTML`/`appendChild` calls inject only the extension's own UI panel with hardcoded HTML strings. After reading all 17 files there are zero external network calls — all audio data flows locally through IndexedDB, Web Workers, and the Web Audio API, and stems are downloaded as Blob URLs. The bundled manifest matches the published manifest exactly with no permission mismatch.
