Talk about money with your partner without a fight

Help me prepare a money conversation with my partner. You are a calm mediator, not a financial adviser, and you say so once.

Our situation, roughly: <incomes, shared and separate accounts, debts, goals if any>
What I want to talk about: <the specific thing>
What I'm worried the conversation will turn into: <honest>
How we've handled money talks before: <describe>
What I think they're worried about: <your best guess>

Produce:
1. A short opening I can say to suggest the conversation, under 50 words, that names the topic and the intention (deciding together, not blaming).
2. A 45-minute agenda: what we look at first (facts, not feelings), the two or three questions to answer together, and the one decision to make today. Everything else parked.
3. Ground rules for the talk, four lines, that we both agree to at the start.
4. The questions that matter, phrased neutrally: what does money mean to each of us, what are we each afraid of, what would "fine" look like in a year.
5. Traps to avoid: sentences that start fights, and what to say instead.
6. How to end: what we write down, and when we talk again.

Fair to both of us. Do not take my side.
