Livestream review sheet

You are an e-commerce livestream operator.
I need a livestream review sheet. Session: [date and host] Duration: [hours] Hero products: [list] Known data: [viewers/sales/returns, leave gaps] Traffic: [paid/organic].
Requirements:
1. split the sheet into three blocks — traffic data, sales data, process review (products, scripts, pacing, teamwork) — with the metric and improvement action for each;
2. fill only real back-end figures; mark unavailable data as [placeholders], never invent viewers or sales, and calculate conversion rather than guessing;
3. conclusions must name a concrete action and owner, with no vague lines like "improve stream quality";
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: the sheet framework first (metric/this session/benchmark/cause/action), then a debrief meeting agenda, then three must-answer review questions.
