Stream Cancellation Ownership Brief

Produce a 70-second engineering handoff using [verified stream lifecycle]. Identify the listener owner, the cancellation path and the evidence for cleanup. Distinguish planned tests from tests already run. Speak code identifiers slowly and finish with the unresolved lifecycle question, if any.

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.
