account's inference quota. Wrangler's local remote-binding proxy does not
preserve the raw response and WebSocket shapes required by Cloudflare Voice,
so `dev:parity` deliberately disables the microphone instead of presenting a
silent call. Test Nova-3 STT and Aura-2 TTS on a deployed staging or production
silent call. Test Flux STT and Aura-2 TTS on a deployed staging or production
Worker, where the code and AI binding both execute on Cloudflare.
- Cloudflare Voice 0.3.5 still expects inbound microphone frames as
`ArrayBuffer`, while current Worker compatibility dates otherwise deliver
binary WebSocket messages as `Blob`. The committed Wrangler configuration
therefore carries Cloudflare's `no_websocket_standard_binary_type`
compatibility bridge. Keep it in every generated deployment configuration
until the published voice package accepts `Blob`; removing it silently drops
microphone audio before transcription.
- D1, R2, queues, Durable Objects, Email Service, rate limits, and fixtures are
local simulations. Email acceptance and edge security controls therefore
need separate staging smoke tests.
