Promise Any Empty Input Readback

Use [Promise.any call site], [runtime] and [empty-input expectations]. Produce a 55-second engineering handoff explaining what the supplied empty-input test actually observes and how the caller handles rejection. Distinguish observed error shape from assumptions about other runtimes.

Use only the supplied facts and approved wording. If a necessary script or timing reference is missing, ask for it first. Produce the audio when supported; otherwise return the complete spoken script with pauses and a short production cue sheet, clearly labeled as a script. Use original voices and keep speech intelligible without music. Never claim an audio file exists unless it was generated.
