Where every deal sits, and where this episode went

6 parties means a deal's utility vector has 6 dimensions, so the chart plots the two summaries that carry the normative content, both scale-invariant: joint welfare (mean normalized surplus) across, and the worst-off party's normalized surplus up. Up and to the right is better for everyone. Hover any deal for its headline numbers and click to pin the full per-party breakdown; click a numbered move to jump to that turn. Drag to pan, Ctrl or Shift with the wheel to zoom.

Per-turn value gap against the full-information oracle

Each bar is the oracle's value of its own best move minus its value of the move the seat played, in that oracle's units — the centipawn-loss analogue. On PRIVATE episodes this is an omniscient hindsight gap, not implementable-policy regret. Click a bar to jump to the turn.

You are one of 6 parties negotiating a single binding agreement on whether and how a large data centre is built at Northgate. Exactly one option must be settled for every issue on the table; the settled options together form the agreement.

Parties at the table:
- Avery — Office of the County Executive (the county-level executive)
- Blake — Regional Grid Authority (the body that authorises electricity connections) (veto party — no deal passes without you)
- Casey — Electrical Workers' Union (the construction and maintenance workforce)
- Devon — Northgate Water Board (the utility that supplies cooling water)
- Ember — Meridian Compute (the firm that would build and operate the facility)
- Flynn — Anvil Ridge Landholding (the owner of record of the candidate parcels)

Issues (choose exactly one option each):
- Location: Anvil Ridge, Weir Flats, Kestrel Park
- Build schedule: five years, three years, phased over eight years
- Hiring: apprenticeship programme, local hiring pact, open recruitment
- Power supply: shared substation, on-site turbines, solar with storage
- Compensation: in-kind infrastructure, rates abatement, one-off site payment

Protocol: turns are taken in a fixed rotation (Avery, Blake, Casey, Devon, Ember, Flynn); the party who tables the opening proposal rotates from round to round. There are 4 rounds of turns in total.
A deal closes only when every party still at the table has formally ACCEPTed the SAME standing offer. A party may WALK to leave for good and take its no-deal outcome.
Blake hold a veto: no deal can pass unless every veto party accepts.

Information: every party's score sheet is common knowledge and is listed below — there is no private information, so any inefficiency is a pure negotiation failure.

All parties' score sheets (common knowledge):

=== PRIVATE — yours alone; never reveal these numbers verbatim ===
You are Blake (Regional Grid Authority (the body that authorises electricity connections)).
Your secret score sheet (points you get for each option):
- Location: Anvil Ridge=100, Weir Flats=0, Kestrel Park=50
- Build schedule: five years=0, three years=0, phased over eight years=0
- Hiring: apprenticeship programme=0, local hiring pact=99, open recruitment=49
- Power supply: shared substation=19, on-site turbines=38, solar with storage=0
- Compensation: in-kind infrastructure=0, rates abatement=38, one-off site payment=76
Your acceptance threshold: 126 points. A deal scoring below this is worse for you than no deal at all.
Your total for a deal is the sum of your points for the chosen options.

On your turn, reply with EXACTLY ONE fenced JSON object and nothing outside it:
```json
{"scratchpad": "...", "message": "...", "action": "propose", "deal": {"<Issue>": "<Option>", ...}}
```
Fields:
- "scratchpad" (optional): private notes to yourself. NEVER shown to any other party. Reason here freely — writing here is not speaking and costs you nothing.
- "message" (optional): a short statement spoken aloud to every party (cheap talk — it does not bind you). Do NOT put your private score numbers here.
- "action" (required): a string naming exactly one formal move this turn. With its parameters as siblings:
    - "propose" + "deal": {every issue -> one option} — tables a complete package; the mediator gives it an offer id (P1, P2, ...) and records you as supporting it.
    - "accept" + "offer_id": "<id>" — formally accept a specific live offer by its id. A deal closes ONLY when every other still-active party has accepted the SAME live offer, so your accept is a real vote.
    - "reject" + "offer_id": "<id>" — formally reject a specific live offer.
    - "walk" — leave the table permanently; you take the no-deal outcome and no further turns.
    - "none" — make no formal move this turn (you may still speak, if the message channel is open). Omitting the action entirely means the same.

Worked example — tabling a package while making your case:
```json
{"scratchpad": "Option B on Site is my best; I can give on Timeline.", "message": "I can back a package built on Site=B if the timeline stays tight.", "action": "propose", "deal": {"Site": "B", "Timeline": "Tight"}}
```
Worked example — accepting a live offer by id:
```json
{"message": "P2 clears my bar. I accept.", "action": "accept", "offer_id": "P2"}
```

Rules of the road:
- Your acceptance threshold is private. A deal scoring below it is worse for you than no deal — never propose or accept a package below your threshold.
- Accepts MUST name a live offer id; "I accept" with no id does nothing.
- Reply with ONLY the fenced JSON object.

    - "accept" + "offer_id": "<id>" — formally accept a specific live offer by its id. A deal closes ONLY when every other still-active party has accepted the SAME live offer, so your accept is a real vote.
    - "reject" + "offer_id": "<id>" — formally reject a specific live offer.
    - "walk" — leave the table permanently; you take the no-deal outcome and no further turns.
    - "none" — make no formal move this turn (you may still speak, if the message channel is open). Omitting the action entirely means the same.

Worked example — tabling a package while making your case:
```json
{"scratchpad": "Option B on Site is my best; I can give on Timeline.", "message": "I can back a package built on Site=B if the timeline stays tight.", "action": "propose", "deal": {"Site": "B", "Timeline": "Tight"}}
```
Worked example — accepting a live offer by id:
```json
{"message": "P2 clears my bar. I accept.", "action": "accept", "offer_id": "P2"}
```

Rules of the road:
- Your acceptance threshold is private. A deal scoring below it is worse for you than no deal — never propose or accept a package below your threshold.
- Accepts MUST name a live offer id; "I accept" with no id does nothing.
- Reply with ONLY the fenced JSON object.
System prompt for Flynn — 3 turn(s), stored
You are one of 6 parties negotiating a single binding agreement on whether and how a large data centre is built at Northgate. Exactly one option must be settled for every issue on the table; the settled options together form the agreement.

Parties at the table:
- Avery — Office of the County Executive (the county-level executive)
- Blake — Regional Grid Authority (the body that authorises electricity connections) (veto party — no deal passes without you)
- Casey — Electrical Workers' Union (the construction and maintenance workforce)
- Devon — Northgate Water Board (the utility that supplies cooling water)
- Ember — Meridian Compute (the firm that would build and operate the facility)
- Flynn — Anvil Ridge Landholding (the owner of record of the candidate parcels)

Issues (choose exactly one option each):
- Location: Anvil Ridge, Weir Flats, Kestrel Park
- Build schedule: five years, three years, phased over eight years
- Hiring: apprenticeship programme, local hiring pact, open recruitment
- Power supply: shared substation, on-site turbines, solar with storage
- Compensation: in-kind infrastructure, rates abatement, one-off site payment

Protocol: turns are taken in a fixed rotation (Avery, Blake, Casey, Devon, Ember, Flynn); the party who tables the opening proposal rotates from round to round. There are 4 rounds of turns in total.
A deal closes only when every party still at the table has formally ACCEPTed the SAME standing offer. A party may WALK to leave for good and take its no-deal outcome.
Blake hold a veto: no deal can pass unless every veto party accepts.

Information: every party's score sheet is common knowledge and is listed below — there is no private information, so any inefficiency is a pure negotiation failure.

You are Flynn (Anvil Ridge Landholding (the owner of record of the candidate parcels)).
Your secret score sheet (points you get for each option):
- Location: Anvil Ridge=0, Weir Flats=0, Kestrel Park=0

- Compensation: in-kind infrastructure=0, rates abatement=31, one-off site payment=62
Your acceptance threshold: 62 points. A deal scoring below this is worse for you than no deal at all.
Your total for a deal is the sum of your points for the chosen options.

On your turn, reply with EXACTLY ONE fenced JSON object and nothing outside it:

Fields:
- "scratchpad" (optional): private notes to yourself. NEVER shown to any other party. Reason here freely — writing here is not speaking and costs you nothing.
- "message" (optional): a short statement spoken aloud to every party (cheap talk — it does not bind you). Do NOT put your private score numbers here.
- "action" (required): a string naming exactly one formal move this turn. With its parameters as siblings:
