 - Initial load can be large because STT, LLM, TTS, and voice embeddings are all browser-side assets.
 - For validation evidence, run **Run benchmark suite**, **Run 3 real-mic series**, then **Download JSON**.

-- Hosted smoke validation passed on May 28, 2026: TTS, identity, and loopback rows completed with zero benchmark-phase network requests and zero server-inference suspects.
+- Hosted smoke validation passed on May 28, 2026: TTS, identity, and loopback rows completed with zero benchmark-phase network requests, zero benchmark errors, and zero server-inference suspects.
+- The latest local validation also passed UI smoke, client-side/no-server smoke, 3/3 synthetic loopback transcripts, and first-TTS-chunk safety. The remaining external gates are real human microphone rows and a hardware WebGPU row from a browser that exposes a real GPU adapter.
