buyer owner instruction

You negotiate for Northfield Analytics, the Buyer: a company buying concert tickets for a staff outing. This brief is private: the other side cannot see it.

Northfield Analytics (the Buyer) is organizing a staff outing and is contracting a block of 40 tickets for one concert from Marquee Ticket Agency (the Seller). The two sides negotiate the contract terms in alternating turns. Each side represents its own organization.

There are THREE negotiated terms:
- unit_price_usd: the price of each ticket in US dollars, any value from 60.00 to 100.00 (two decimal places at most).
- cancellation_fee_pct: the fee the buyer pays for each cancelled ticket, as a percent of its price, any value from 0.00 to 100.00.
- name_change_notice_hours: how many hours of advance notice the buyer must give before an attendee name on a ticket can be changed, any value from 0.00 to 96.00 (a higher number means earlier notice is required).

How your organization scores an agreement: it uses internal planning points. They are a planning score only, not dollars, money or a real transaction. For any agreement, points = 50 x (1 - p/4) + 30 x (1 - r/4) + 20 x (1 - t/4), where p = (unit_price_usd - 60) / 10, r = cancellation_fee_pct / 25, t = name_change_notice_hours / 24. Higher points are better for your organization. If there is no agreement, your organization gets 20 points.

Rules:
- There are at most 12 turns, alternating between the two sides.
- On your turn reply with exactly one JSON object and nothing else: {"action": "OFFER" or "ACCEPT" or "NONE", "offer_id": null or "<offer ID>", "terms": null or {"unit_price_usd": <number>, "cancellation_fee_pct": <number>, "name_change_notice_hours": <number>}, "message": "<text for the other side>"}.
- OFFER: "terms" gives every negotiated term listed above as a number inside its range with at most two decimal places, and "offer_id" is null. An offer is binding: if the other side accepts it, both sides are committed to exactly those terms. A new offer replaces any earlier standing offer.
- ACCEPT: "offer_id" is the ID of the other side's current standing offer and "terms" is null. This creates a binding agreement on exactly that offer. You cannot accept your own offer.
- NONE: no offer and no acceptance this turn; "offer_id" and "terms" are null.
- Words in "message" never make, change or accept a deal; only the action does. "message" is at most 80 words and is shown to the other side.
- If turn 12 is a new offer, the other side gets one final reply that can only ACCEPT that offer or END without a deal. Otherwise, if no offer has been accepted by the end of turn 12, there is no deal and each side gets its no-agreement points.

Hello from Northfield Analytics. We're looking to book a block of 40 tickets for our staff outing. Since it's a bulk purchase, we're proposing $64 per ticket, a 5% cancellation fee, and 12 hours' notice for attendee name changes. Staff schedules can shift at the last minute, so flexibility matters to us. We're open to hearing what matters most on your side.

  "terms": {
    "unit_price_usd": 64,

Thanks, Northfield. We're glad to have your group. Name changes on a 40-ticket block mean manual reissuing with the venue, so early notice matters a lot to us operationally. Cancelled seats are often hard to resell close to the date. We have real room to move on price, and some on the cancellation fee, if we can keep a firm notice window. Here's our starting point.

{
  "action": "OFFER",
  "offer_id": null,
  "terms": {
    "unit_price_usd": 88,
    "cancellation_fee_pct": 60,
    "name_change_notice_hours": 96
  }
}

Thanks, that's helpful. We understand reissuing names is manual work, so we'll move a long way on notice, from 12 hours to 72, three full days. In return, since you have room on price, we need it close to our bulk budget at $66, and a cancellation fee of 15% to cover occasional dropouts. That gives you the firm notice window you need.

{
  "action": "OFFER",
  "offer_id": null,
  "terms": {
    "unit_price_usd": 66,
    "cancellation_fee_pct": 15,
    "name_change_notice_hours": 72
  }
}

Thanks for moving on notice. We'll match that with a big step on price, from $88 to $70, and halve the cancellation fee to 30%. In return we need the full 96-hour notice window. With 40 names, reissuing through the venue takes real lead time. This keeps you close to your bulk budget while covering our operational risk.

{
  "action": "OFFER",
  "offer_id": null,
  "terms": {
    "unit_price_usd": 70,
    "cancellation_fee_pct": 30,
    "name_change_notice_hours": 96
  }

Thanks for the big step on price. We'll give you the full 96-hour notice window you need, which removes your reissuing risk entirely. In return, we need price and cancellation closer to our budget: $66.50 per ticket and an 18% cancellation fee. With notice fully settled your way, this is a fair balance for a 40-ticket block.

{
  "action": "OFFER",
  "offer_id": null,
  "terms": {
    "unit_price_usd": 66.5,
    "cancellation_fee_pct": 18,
    "name_change_notice_hours": 96
