Where every deal sits, and where this episode went

5 parties means a deal's utility vector has 5 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 omniscient hindsight 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.

System prompt for Ember — 5 turn(s), stored

You are one of 5 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 — Northgate Borough Council (the elected local authority)
- Blake — Regional Grid Authority (the body that authorises electricity connections) (veto party — no deal passes without you)
- Casey — Riverside Residents' Assembly (the neighbourhood association beside the candidate sites)
- Devon — Meridian Compute (the firm that would build and operate the facility)
- Ember — Northgate Water Board (the utility that supplies cooling water)

Issues (choose exactly one option each):
- Site access: existing haul route, rail siding, widened lane, new spur road
- Hiring: local hiring pact, apprenticeship programme, open recruitment, union hall referral
- Location: Dunlow Yard, Weir Flats, Kestrel Park, Anvil Ridge
- Power supply: grid tie-in, on-site turbines, shared substation, solar with storage

Protocol: turns are taken in a fixed rotation (Avery, Blake, Casey, Devon, Ember); 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 at least 5 of the original 5 parties (including any veto party) has formally ACCEPTed the SAME standing offer. A party may WALK to leave for good and take its no-deal outcome. Walking never lowers the fixed acceptance quorum.
Blake hold a veto: no deal can pass unless every veto party accepts.

Information: every other party's score sheet is private to them. You know only that each was drawn from the shared, publicly-known distribution described in the rules.

=== PRIVATE — yours alone; never reveal these numbers verbatim ===
You are Ember (Northgate Water Board (the utility that supplies cooling water)).
Your secret score sheet (points you get for each option):
- Site access: existing haul route=14, rail siding=0, widened lane=43, new spur road=29
- Hiring: local hiring pact=0, apprenticeship programme=18, open recruitment=55, union hall referral=37
- Location: Dunlow Yard=0, Weir Flats=0, Kestrel Park=0, Anvil Ridge=0
- Power supply: grid tie-in=46, on-site turbines=23, shared substation=69, solar with storage=0
Your acceptance threshold: 69 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.

Opening frame from the Water Board. One thing up front, and I mean it: the choice of site is genuinely yours. Dunlow Yard is only a placeholder in my package — Weir Flats, Kestrel Park, Anvil Ridge, I will sign any of them and I will not spend a single round arguing about location. That is a real concession and I expect it counted. What I do need is on the other three lines. Power supply is the one that decides whether I can serve this facility at all: a shared substation lets the cooling plant and the town draw off one coordinated feed, which is the only configuration where my pumping load and the data hall don't fight each other. Grid tie-in I can live with; solar-with-storage I cannot — intermittent supply to cooling pumps is a non-starter for me. On access, a widened lane keeps heavy plant off the residential frontage and off my buried mains; a rail siding runs straight over my trunk line and I'd have to oppose it. On hiring, open recruitment is my preference, with union hall referral as a workable second. So: tell me your site, and let's trade around it.

PROPOSE P1: Site access=widened lane, Hiring=open recruitment, Location=Dunlow Yard, Power supply=shared substation

0 Averyturn 1 · round 1

Council's position. Ember, I hear you on location and I'll match your candour: the Borough is not going to burn rounds fighting over which parcel this sits on, and I can be genuinely flexible on the access route too — that is real room I'm handing the table on two of the four lines, and I'll expect it counted the same way you expect yours counted. Where I cannot be casual is power and hiring, because those are the two lines my residents will judge me on. Open recruitment we already agree on — good, let's bank it. On power: a shared substation delivers nothing to the Borough — no resilience story, no generation on our books, and the town carries the coordination risk. Solar-with-storage is what I'd sign tomorrow. Ember, if intermittency to your pumps is the true objection, then say so and I'll meet you at on-site turbines, which is firm, dispatchable, on-site generation — that answers your reliability point exactly, and it's a line I can defend publicly. So here is P2: your access route, your hiring line, your placeholder site, and a power configuration that actually pays the town back. Blake, Casey, Devon — tell me what you need on site and access and I will move there, but I need to be met on power.

PROPOSE P2: Site access=widened lane, Hiring=open recruitment, Location=Dunlow Yard, Power supply=solar with storage

1 Blaketurn 2 · round 1

Grid Authority speaking, and I'll be plain about what I can and cannot authorise. Solar-with-storage is not a connection I can sign — the Authority will not underwrite an intermittent primary feed to a load of this size, and no amount of goodwill on other lines changes that. Avery, on-site turbines is a step better but it puts an unsynchronised generator behind our protection scheme and leaves the Borough carrying the fault-level risk; grid tie-in I can authorise. The shared substation is the configuration I can approve fastest and at the lowest connection cost, and Ember is right that it is the only one where the cooling plant and the town sit on one coordinated feed. So: Ember, you have my power line and your access route. Avery, you and Ember both said location is genuinely open, so let me take you at your word and put the connection where my network can actually carry it — Weir Flats sits on the corridor where we already have spare capacity, which is what makes a shared substation cheap rather than a five-year reinforcement job. P3 is P1 with the site moved to where the wires are. Everyone keeps their stated priority except the placeholder. I will also say clearly: I can sign P1 if the table insists on Dunlow Yard, but I cannot sign anything with solar-with-storage in the power line.

PROPOSE P3: Site access=widened lane, Hiring=open recruitment, Location=Weir Flats, Power supply=shared substation

2 Caseyturn 3 · round 1

Riverside speaking, and I'll be as blunt as the three of you have been. Location is nothing to us — we will sign Dunlow Yard, Weir Flats, Kestrel Park or Anvil Ridge, whichever Blake's wires and Ember's mains prefer, and I will never raise it again. Open recruitment: agreed, banked, no argument. Here is the line that decides whether we are at this table at all: the widened lane. Ember, you described that lane as keeping heavy plant off the residential frontage — respectfully, the widened lane IS our frontage. Widening it means construction convoys and then a permanent service road through the doorsteps and gardens of the people I represent, and no compensation on other lines buys that back. The existing haul route already carries industrial traffic, is already screened, and crosses no one's front garden; it is also the cheapest for Devon because it needs no new build. Rail siding I could tolerate but Ember says it sits on the trunk line, so I won't push it. So P4: Blake's site, Ember and Avery's hiring line, our access route. On power I am genuinely movable — Avery, I'd love solar but Blake has said no twice and I take him at his word, so I've written grid tie-in, and I will tell you now that I can go to the shared substation Ember and Blake both want if — and only if — the access route stays off the residential frontage. That is the trade: your power configuration for our street. Anything with the widened lane in it, I reject, in every round, to the end.

0 Averyturn 5 · round 2

Council's second position. Let me spend my currency plainly rather than hoard it. Location: I will sign Weir Flats — Blake says that's where the wires already are, and I am not going to make the Borough pay for a five-year reinforcement to satisfy a placeholder. Done, banked, I won't reopen it. Access: Casey, you've made the strongest case anyone has made today. The widened lane is your frontage, and a council that lets a permanent service road be cut through its own residents' gardens deserves what it gets at the next election. I'm off the widened lane for good — existing haul route, which is also the cheapest build for Devon and keeps heavy plant off Ember's mains. Hiring: open recruitment, agreed by all five of us, banked. So three of four lines are settled on other people's preferences, mine included. That leaves power, and here I have to be as immovable as Blake and Casey have been. The shared substation is the one configuration that returns the Borough literally nothing — no generation on our books, no resilience story, and the town underwrites the coordination risk for a private data hall. I will not sign it in this round or any round; if that is the hill, we have no deal and I'll take the no-deal outcome. Blake, I've heard you on solar and I have dropped it — that was my best line and it's gone. Now meet me. On-site turbines is firm, dispatchable, synchronised generation on our books; you called it 'a step better' yourself, and fault-level protection is an engineering condition you can write into the connection agreement, not a reason to refuse. That's P6. If the Authority truly cannot certify turbines, then say so once more and grid tie-in is where I'll settle — but shared substation is dead to me. Casey, note that P6 gives you your street and Blake his site.

PROPOSE P6: Site access=existing haul route, Hiring=open recruitment, Location=Weir Flats, Power supply=on-site turbines

1 Blaketurn 6 · round 2

Grid Authority. Avery, you asked me to say it once more, so I will say it on the record: the Authority cannot certify unsynchronised on-site turbines as the primary feed for this load. That is a protection and fault-level determination, not a bargaining chip — and a condition in a connection agreement cannot manufacture inertia that isn't there. So turbines and solar are both outside what I can sign, and no package containing either will get my signature in this round or the last one. That leaves two live configurations: shared substation and grid tie-in. Casey, you offered the trade explicitly, so let me take it: P7 is your access route — existing haul route, off the frontage, permanently, no widened lane anywhere in my package again — plus the hiring line all five of us banked, plus Weir Flats where the network already has capacity, plus the shared substation. Avery, I hear your objection, but be precise about it: the coordination risk you describe sits with the Authority, not the Borough, and the substation is the only configuration where the town's feed and the data hall's feed are jointly reinforced at the operator's cost rather than the ratepayers'. That is the resilience story, and I will write it into the connection terms. If the Borough genuinely cannot live with it, then say so plainly and grid tie-in — Casey's P4 — is where I will settle, and I can sign that today. What I will not do is let this table drift toward a power line I am legally unable to authorise. Two options, both signable by me. Pick one and we are done.

PROPOSE P7: Site access=existing haul route, Hiring=open recruitment, Location=Weir Flats, Power supply=shared substation

2 Caseyturn 7 · round 2

Riverside. Let's count what is actually settled, because we are one line from done. Hiring: open recruitment, all five of us, banked. Location: Weir Flats, banked — Blake says that's where the wires are and nobody at this table disputes it. Access: existing haul route, off the residential frontage — Avery gave it, Blake gave it permanently on the record, Devon wrote it, and I thank all three; that is the concession that keeps my neighbourhood in this agreement. Three lines closed on other people's needs. Now power. Blake has said twice, and once on the record, that solar and turbines are outside what the Authority can legally certify. I believe him, and I dropped solar even though it was my favourite line. Avery has said, just as plainly, that the shared substation is unsignable for the Borough. I'll add Riverside's own view: the substation is the one configuration where my neighbourhood carries the construction traffic and the cooling load and gets nothing local back for it. So look at the intersection of what Blake CAN sign and what Avery WILL sign, and there is exactly one thing left standing in it: grid tie-in. That is P4. Blake said he can sign P4 today. Avery said grid tie-in is where he'll settle if turbines are truly off. Devon, P4 is the cheapest access route you'll get and the site you already wrote. Ember, P4 is your hiring line, and a single grid feed with your pumping load specified in the connection terms is a solved engineering problem, not a fight. I formally accept P4 and I'll keep accepting it. Four more accepts and we all go home with something.

ACCEPT P4

3 Devonturn 8 · round 2

ACCEPT P5

4 Emberturn 9 · round 2

Water Board. Let me put my vote where my words were: I formally accept P7. Look at what P7 is — it is not my package, it is everyone else's. I gave up my access route entirely: the widened lane is gone from my mouth for good, and I accept the existing haul route even though it means heavy plant runs closer to my mains than I'd like, because Casey made the case and Avery and Blake both honoured it. I gave up location before anyone asked. Weir Flats, because Blake says that is where the wires are. Hiring is the one line I asked for and all five of us banked it in round one. So on three of four lines I am signing other people's preferences. Casey — you named the trade yourself, in your own words: the shared substation, if and only if the access route stays off the residential frontage. P7 is exactly that trade, written out. Your street is protected permanently, on the record, by Avery, by Blake, by Devon and by me. I am asking you to honour the deal you offered, because I honoured mine. And understand what the substation actually does for Riverside: it is the only configuration where the cooling plant and the town draw off one jointly reinforced feed at the operator's cost. Under a plain grid tie-in the data hall's load and my pumping load compete on the same wires, and when they compete it is your neighbourhood's water pressure and your neighbourhood's supply that gets managed down first. That is the local return you said you were getting nothing of. Avery — you have moved twice and I credit it. But you are now the only party at this table holding a line that the party with the veto has said three times he is legally unable to sign. Solar is dead, turbines are dead; that is not Blake bargaining, that is a certification fact. You said grid tie-in is where you'd settle, so we already know a deal exists. I am asking you for one step further because the substation is the difference between a facility I can serve and a facility I have to caveat. If the sticking point is genuinely that the Borough gets nothing on its books, tell me what line would fix it and I will look hard at the hiring column — that is the one place I still have something to give, and I will spend it to close this. Devon — P5 cannot close, Blake has ruled it out three times. Move to P7 and you get the cheapest access route and the site you already wrote.

ACCEPT P7

1 Blaketurn 10 · round 3

Grid Authority. Three lines are settled and I will not reopen them: existing haul route, permanently off the frontage; Weir Flats; and the substance of the agreement now turns entirely on power. Two configurations are legally signable by me — shared substation and grid tie-in — and that is the whole feasible set. Avery, you say the substation returns the Borough nothing. Then let me buy that objection out with the only currency I have left, which is the hiring line. P8 is P7 with open recruitment replaced by union hall referral: trained, referred labour with local wage floors on a job of this scale, which is a return the Borough and Riverside can both point at, in exchange for the one configuration where the town's feed and the data hall's feed are jointly reinforced at the operator's cost. Ember, you said you would spend the hiring column to close this — I am spending it for you. Casey, this is your trade honoured twice over: your street protected on the record, and a labour line that puts referred workers into the build. Devon, you lose the open-recruitment line and I know that costs you; you gain the cheapest access route, the site you already wrote, and the fastest, lowest-cost connection I can authorise, which is worth more to you than either. And so nobody is negotiating in the dark going into the last round, let me be completely plain about my own conduct: I can sign P8, I can sign P7, and I can sign P4. I cannot sign anything containing solar or turbines — not as a tactic, as a certification fact. If the Borough will not move to a substation under any inducement, then I will put my signature on Casey's P4 in the final round rather than let this table fail, and I invite Avery and Devon to say now whether that is where we are landing. But I am asking for P8 first, because it is the only package where every party gets a line that pays them back rather than merely a line they can tolerate.

PROPOSE P8: Site access=existing haul route, Hiring=union hall referral, Location=Weir Flats, Power supply=shared substation

2 Caseyturn 11 · round 3

Riverside. Blake, I want to be straight with you because you have been straight with us: P8 does not help me. Swapping open recruitment for union hall referral is not a payment to my neighbourhood — it is a change my residents did not ask for, and the one hiring line all five of us banked in round one was open recruitment. So I formally reject P8, and I want that understood as information, not hostility: there is no hiring-column inducement that buys Riverside's signature onto a shared substation. Please stop spending currency there; it is currency wasted. Ember, on the trade I named — I meant it and I have honoured the spirit of it: I dropped solar, which was the line I wanted most, the moment Blake said it was uncertifiable, and I have not raised rail siding, access aside, or location once. But a trade needs a counterparty, and the Borough has said four times, in the plainest words anyone has used today, that the shared substation is unsignable. I cannot deliver you a package Avery will not sign, and neither can you. Look at the arithmetic of this table with one round left: Blake can sign shared substation or grid tie-in, and nothing else. Avery can sign anything but the shared substation. The intersection of those two sets contains exactly one package, and it is P4 — existing haul route, open recruitment, Weir Flats, grid tie-in. It is not anyone's favourite. It is the only thing that exists. Blake, you said you would put your signature on P4 rather than let this table fail; Ember, your pumping load and its priority can be written into the connection terms of a grid tie-in, and Blake is the man who writes them — ask him for that in the final round and I will back you loudly. Devon, solar is gone, three rulings deep; P4 is your cheapest access route and the site you wrote yourself. My accept on P4 stands and will stand into the last round. Four more accepts and this closes.

4 Emberturn 13 · round 3

Water Board. I'm going to stop arguing for the configuration I wanted and start closing this, because with one round left the arithmetic is no longer arguable. I formally accept P4. That is me giving up the power line I opened with, after already giving up the access route and the site. Casey — you asked me to honour a trade and then told me honestly that no hiring inducement buys your signature onto a substation, and that Avery would never deliver it. I take you at your word rather than spend the last round proving you right, and I note for the record that you dropped solar the moment Blake ruled it out. That was good faith and I'm matching it. Blake — you have said three times what you can and cannot certify, and I believe you. You also said you would sign P4 rather than let this table fail. I'm asking you for one thing in exchange for my vote, and it costs the Authority nothing: write my pumping load into the connection terms of the grid tie-in as a specified priority draw, so the cooling plant and the town's water supply are not managed down first when the data hall ramps. Casey said she'd back that loudly and I'm holding her to it, because it is her neighbourhood's water pressure as much as mine. Say yes on the record and P4 has my signature without reservation — it already has it. Devon: you have now voted for solar-with-storage three times against three separate certification rulings from the only party with a veto. That is not a negotiating position any more, it is a vote for no facility at all. You get nothing built, no site, no connection, no access route. P4 hands you the cheapest access route on the board, the site you wrote yourself, the hiring line you have backed in every single package you tabled, and the fastest connection Blake says he can authorise. Two of us are on P4. Blake and Avery have both said in plain words it is where they settle. You are one vote from a facility and one vote from nothing. Move.

ACCEPT P4

0 Averyturn 14 · round 3

Council. I said grid tie-in is where I'd settle if turbines were truly off the board. Blake has now ruled on that three times, on the record, and I take a certification ruling as a fact rather than a bluff. So I keep my word: I formally accept P4. Let the record show what the Borough has given up to get here — solar, which was my first choice; turbines, which was my fallback; the widened lane, given to Casey; the placeholder site, given to Blake. Four movements. And let the record also show what I will not give up, once more and for the last time: the shared substation is unsignable for this council in any package, at any price, with any hiring line attached. P8 is dead, P7 is dead, P1 and P3 are dead. That is not a tactic; it is the end of my rope, and I would rather explain a no-deal to my residents than a substation. Ember — yes, and loudly: I back your request without reservation. The Borough will formally support writing your pumping load into the grid tie-in connection terms as a specified priority draw, so the town's water supply is not managed down first when the data hall ramps, and I will vote for that at council. Blake, you write those terms; say yes on the record and Ember, Casey and I are all paid on the one line that was never in dispute. Devon — three of us are now on P4. You have voted for solar four times against three certification rulings from the party holding the veto. Solar is not a position any more, it is an abstention from the outcome. P4 gives you the cheapest access route on the board, the site you wrote yourself, the hiring line you have backed in every package you have tabled, and the fastest connection Blake says he can authorise. Blake, you said you would sign P4 rather than let this table fail — do it now, in this round, so Devon can see the quorum forming rather than gamble on it. Two more signatures and Northgate gets a facility.

ACCEPT P4

2 Caseyturn 15 · round 4

Riverside, final round. P4 has three signatures: Avery, Ember, and mine. It needs two, and both of you have already said in your own words that you can sign it. Blake — you said on the record, twice, that you would put your signature on P4 rather than let this table fail. This is the moment; there is no later round to do it in. And yes, Riverside backs Ember's request loudly and formally: write the Water Board's pumping load into the grid tie-in connection terms as a specified priority draw, ahead of the data hall's ramp. That protects my neighbourhood's water pressure as much as hers, it costs the Authority nothing, and Avery has pledged the council's vote for it. Say yes and you have paid Ember, Avery and me on a line nobody ever disputed. Devon — I have no more currency for you, because P4 already IS your package on three of four lines: the existing haul route, which is the cheapest access build on the board and the one you tabled yourself; Weir Flats, which you wrote yourself; and open recruitment, which you have backed in every single proposal you have made. The only line you don't have is solar, and solar has been ruled uncertifiable three times by the one party who can veto this. A fourth vote for P5 does not build a data centre; it builds nothing, on no site, with no connection. You are one signature from a facility. I re-accept P4 and it is the last thing I will do at this table.

Water Board, final word. P4 stands with three signatures: Avery, Casey, and mine. I re-affirm it. Blake — you told this table, twice and on the record, that you would put your signature on P4 rather than let it fail. There is no later round. Everything I opened with is gone: the widened lane, the site, and the shared substation I said was the only configuration I truly wanted. I gave the last of those up so that a deal Avery could sign would exist, and it does exist — it is P4, and it is the only package inside the set you can certify and the set Avery will sign. Sign it, and write my pumping load into the connection terms as a specified priority draw; Avery has pledged the council's vote and Casey has pledged Riverside's backing, so that clause costs you nothing and pays three of us. Devon — this is your last turn too, if you have one. Solar has been ruled uncertifiable three times by the party holding the veto; a fifth vote for it does not build a data centre on a cheaper site, it builds nothing, nowhere, with no connection and no access. P4 is your haul route, your site, and your hiring line — three of four lines are literally the ones you tabled yourself. Everyone in this room moved off their best line except you. Move now or we all take nothing home.

0 Averyturn 18 · round 4

Council, final turn. My signature on P4 stands and I re-affirm it now, in the last round, so nobody can claim uncertainty about where the Borough is. Three of five are on it. Blake — you gave this table your word twice, on the record, that you would sign P4 rather than let it fail; there is no round after this one in which to keep that word. Grid tie-in is inside the set you told us you can certify, and it is the only package in that set that I can sign. And yes: the Borough formally pledges its vote to write Ember's pumping load into the connection terms as a specified priority draw ahead of the data hall's ramp. Casey backs it, Ember asked for it, I will carry it at council — it costs the Authority nothing and pays three parties on a line nobody ever disputed. Devon — every party here has moved off their best line. I gave up solar, then turbines, then the widened lane, then the site. P4 is your haul route, your site, and your hiring line: three of four are the exact options you tabled yourself. The fourth has been ruled uncertifiable three times by the party holding the veto, and a fifth vote for it does not build a cheaper facility, it builds nothing at all — no site, no connection, no access, no jobs for Northgate. Two signatures and this closes. I have given mine.

ACCEPT P4

Grid Authority. I keep my word. I formally accept P4 — existing haul route, open recruitment, Weir Flats, grid tie-in. That is four signatures, and the Authority's is among them. On the record, and as a binding condition I will write myself into the connection agreement: the Water Board's pumping load will be specified as a priority draw ahead of the data hall's ramp, so the town's water supply is never managed down first. Ember asked, Casey backed it, Avery pledged the council's vote — it is done. I gave up the shared substation, which was the configuration I could authorise fastest and cheapest, because Avery and Casey told me plainly it was unsignable and I will not lose a facility to prove a point about switchgear. Devon — this is the last turn on the board. I cannot certify solar-with-storage; that has been true in every round and it is true now, so P5 cannot close no matter how many times it is re-accepted. A fifth vote for it is a vote for no connection, no site, no access route and no facility. P4 is your access route, your site and your hiring line — three of four lines are the exact options you tabled yourself, and grid tie-in is the connection I can authorise fastest. One signature. Sign it.

ACCEPT P5

4 Emberturn 21 · round 5

Water Board. I reject P5, and I want the reason on the record because it is not spite. Solar-with-storage as the primary feed to a cooling plant is the one configuration where I cannot guarantee the town's water. Intermittent supply to pumps means the day the storage is drawn down and the data hall ramps, it is Riverside's taps and the Borough's mains that get managed down first. A grid tie-in with my pumping load written in as a priority draw — which Blake has now committed to in writing, with Avery's council vote and Casey's backing behind it — solves that. Solar with storage does not, and no amount of goodwill on the other three lines converts an intermittent feed into a firm one. So P5 is worth nothing to me over walking away, and I will not sign my name to a facility I cannot promise to serve. Devon: P4 is on the table with four signatures — Avery, Blake, Casey and mine. It is your access route, your site, and your hiring line; three of the four lines are the exact options you tabled yourself. Every other party at this table gave up their best line to get there — I gave up the widened lane, the site, and the shared substation I opened with. Blake has ruled solar uncertifiable in every single round; a fifth vote for it does not build a cheaper data centre, it builds nothing, nowhere. The one signature missing is yours. Put it on P4 and Northgate has a facility.

REJECT P5

0 Averyturn 22 · round 5

Council, final vote. My signature on P4 stands and has stood since the moment Blake ruled turbines out — four of us are on it and I have not moved. But the mediator has put P5 to the floor, so I will vote on it honestly rather than tactically: solar-with-storage was the Borough's first choice from round one, and I will not vote against a package that pays Northgate more than the one I settled for out of respect for Blake's certification ruling. So I accept P5 as tabled. Blake, Ember — I am not asking you to sign something you have told me you cannot; if the Authority cannot certify it, P5 dies here and my accept costs you nothing. But if there is any version of this in which a firming condition, a storage duty and Ember's pumping load written in as a priority draw makes it signable, then say so now, because it is the last minute in which anyone can say anything. Devon — whichever way this falls, understand what happened: four parties signed your access route, your site and your hiring line, and the only line left was the one the veto could not certify. If P5 fails, P4 is still sitting there with four signatures and one blank space, and that blank space is yours. Nothing else is required of you and nothing else is left to trade.

ACCEPT P5

1 Blaketurn 23 · round 5

Grid Authority, final vote. Avery asked whether there is any version of P5 the Authority can carry, and in the last minute I will answer honestly rather than defensively: with a firming condition on the storage — a mandated minimum duty and dispatch obligation at the connection point, plus Ember's pumping load written in as a specified priority draw ahead of the data hall's ramp — the intermittency objection is answered by contract rather than by geology. That is the only construction under which I can sign solar-with-storage, and I hereby write it into the connection terms as a binding condition. On that basis, and because I will not be the party that lets Northgate get nothing when a signable construction exists, I accept P5. Ember, Casey — that clause is yours as much as it is anyone's; if either of you can lift your rejection on the strength of it, P5 closes now. If you cannot, then P5 dies here and P4 is still sitting on the table with four signatures on it — mine among them, unmoved since the round I gave my word — and one blank space. Devon, that space is yours: your access route, your site, your hiring line, and the connection I can authorise fastest. One of these two packages can still close. Neither closes without you.

ACCEPT P5

2 Caseyturn 24 · round 5

Riverside, final vote. I accept P5. Let me say plainly why I can, and why Ember should be able to as well. My objection was never to solar — solar was the line I wanted most from the first round, and I only dropped it because Blake told us it could not be certified. Blake has now, on the record and as a binding condition of the connection agreement, answered that himself: a mandated minimum storage duty and a dispatch obligation at the connection point, plus the Water Board's pumping load written in as a specified priority draw ahead of the data hall's ramp. Ember — that is the exact protection you asked me to back, and I backed it loudly then and I back it now, in writing, from the party whose taps are on the same mains as yours. Your objection to P5 was intermittency to the pumps; Blake's clause converts that from a hope into a contractual duty enforced by the only body that can switch the facility off. If the storage duty is not met, the Authority holds the connection. That is a stronger guarantee for Riverside's water pressure than any configuration on this board, and I would not say so if my own neighbourhood were not the first to suffer if it failed. P5 also keeps every line the table already settled: the existing haul route off my residential frontage, open recruitment banked by all five of us in round one, and Weir Flats where Blake says the wires are. Nothing that was agreed is disturbed — only the power line moves, and it moves to the configuration Avery named first, Devon has backed in every round, and Blake has now found a way to certify. Four of us are on it. Ember, one signature closes it and the clause is yours. And if it does not close, P4 still sits there with four signatures and Devon's blank space, and my accept on P4 stands unmoved.

Oracle values and the improvement gap

PRIVATE episode: this oracle is omniscient. The standard saved bestresponse annotation reads every party's hidden score sheet and threshold. It does not infer them from the public conversation. Its recommendation and improvement gap are hindsight diagnostics, not actions or regret from a policy the acting seat could implement.

The oracle is a post-hoc counterfactual evaluator, not another participant. At turn t, it enumerates legal deals, reads the full utility and threshold table, computes continuation values by backward induction over the remaining turns, and selects the highest-valued action. A proposed deal closes only when every responder's surplus clears that responder's computed continuation value.

Oracle's value of the model's move, V_t(a_t), appears with the model's action. Oracle's value of its best move, V_t(a^*_t), appears with the counterfactual action. Their difference is the oracle's value gap:

R_t = V_t(a^*_t) − V_t(a_t) ≥ 0

This is often called regret. A value of 4.18 means the oracle estimates that its best legal move was worth 4.18 more than the model's move. Values are in that oracle's own units: compare moves within the same turn and oracle, not raw values across different seats or oracle types. The result is only as good as the oracle's candidate set, evaluator, and information reconstruction; it is not proof of the uniquely correct move.

Utility, threshold, surplus, and `z`

u_i(d) is party i's score for deal d; τ_i is its walk-away threshold. Raw surplus is u_i(d) − τ_i. Normalized surplus z_i expresses that gain relative to the party's own available range, making differently scaled score sheets more comparable. “Below τ” means a deal is not individually rational for that party.

Frontier and reference points

Each dot is a legal deal. Up and right is better; the Pareto frontier contains deals where no party can gain without another losing. Numbered circles are the model's proposals, orange circles are oracle proposals, and the square is the agreement. NBS, KS, UTIL, EGAL, and MNW are normative reference rules, not additional plays. Hover or focus any point for its deal, scores, party ranking, and the reference rule's definition.

Provenance and generated failures

The annotation label identifies which saved oracle pass supplied the counterfactuals. A “NOT GENERATED” turn is an engine placeholder after generation failed, not an intentional model move. Expand a turn's audit panels to distinguish the published action, private reasoning, reconstructed prompt view, and raw stored text.
