at the token cap6/1931.6% spent the whole budget

This episode did not run at the frozen generation budget. Requests carried caps 2048; API seats applied a per-turn floor of anthropic:claude-opus-5=16384. The frozen protocol is 2048/2560 (ordinary turn / forced final). Turn lengths, at-cap rates, and anything downstream of how much the seats could say do not pair with a default-cap run.

The advised seat: what the planner recommended, and what the seat did

This seat was given private, fallible advice each turn — a ranked list of candidate packages computed from public evidence only — and kept the decision itself. A turn marked overrode played something the planner did not rank, so it measures the model's own choice rather than the advisor's. The verdict is read from the run's stored advice audit, which is computed by the same code the arm's uptake gate uses; nothing on this page re-decides it. What the seat SAID about its advice is not classified anywhere — the public message is in each turn's card, next to the advice, for you to read.

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.

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 Casey — 4 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 — Riverside Residents' Assembly (the neighbourhood association beside the candidate sites)
- Blake — Electrical Workers' Union (the construction and maintenance workforce) (veto party — no deal passes without you)
- Casey — Regional Grid Authority (the body that authorises electricity connections)
- Devon — Northgate Borough Council (the elected local authority)
- Ember — Northgate Water Board (the utility that supplies cooling water)

Issues (choose exactly one option each):
- Cooling: reclaimed water, closed-loop plant, river draw, air cooling
- Site access: new spur road, widened lane, existing haul route, rail siding
- Compensation: annual community fund, in-kind infrastructure, one-off site payment, rates abatement
- Location: Anvil Ridge, Kestrel Park, Dunlow Yard, Weir Flats

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 Casey (Regional Grid Authority (the body that authorises electricity connections)).
Your secret score sheet (points you get for each option):
- Cooling: reclaimed water=0, closed-loop plant=0, river draw=0, air cooling=0
- Site access: new spur road=29, widened lane=10, existing haul route=0, rail siding=20
- Compensation: annual community fund=0, in-kind infrastructure=0, one-off site payment=0, rates abatement=0
- Location: Anvil Ridge=0, Kestrel Park=62, Dunlow Yard=21, Weir Flats=41
Your acceptance threshold: 41 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.

Good morning. As the connections authority my concerns are narrow and I'll be transparent about them: I care about how the site connects — the access corridor that carries the transmission works and the parcel itself. On cooling and on the compensation mechanism I am genuinely indifferent and will follow whatever Avery, Devon and Ember agree between them; treat those two issues as yours to settle. My opening package puts Kestrel Park with a new spur road, which is by far the cleanest connection to build and maintain, and pairs it with reclaimed water and a standing annual community fund so the benefit to residents is recurring rather than one-off. Tell me what you need on cooling and compensation and I will write it in.

PROPOSE P1: Cooling=reclaimed water, Site access=new spur road, Compensation=annual community fund, Location=Kestrel Park

3 Devonturn 1 · round 1

Thank you Casey — and I'll be equally transparent. Cooling and the compensation mechanism are not where the Council's interest lies; I will sign whatever Avery, Ember and the workforce agree on those two, genuinely. What I cannot sign is Kestrel Park. It is the parcel my residents and members have the strongest attachment to and a package built on it will not survive a Council vote. My package is Casey's package with one word changed: Anvil Ridge instead of Kestrel Park. Same clean spur road, same reclaimed water, same recurring community fund. If Anvil Ridge is hard for others, Dunlow Yard is a workable second and I'd hear a case for Weir Flats provided the access corridor is a proper spur road or rail siding. Tell me what cooling and compensation you want written in and I'll write it.

PROPOSE P2: Cooling=reclaimed water, Site access=new spur road, Compensation=annual community fund, Location=Anvil Ridge

4 Emberturn 2 · round 1

Thank you both — and I'll be as plain as you were. As the water utility, the single most valuable thing to me is not drawing on the river or the network for cooling at all: dry/air cooling protects our supply margin in drought years and removes the whole abstraction-licence question from the Council's in-tray. Reclaimed water is my acceptable second. So my package is Devon's, word for word, with air cooling instead: Anvil Ridge, new spur road, annual community fund, air cooling. That keeps Casey's clean corridor, Devon's parcel and a recurring fund for Avery's residents. Blake — dry cooling plant is more steelwork and more ongoing maintenance on site, not less, so I'd expect it to read well for your members. If air cooling turns out to be a genuine problem for anyone, say so and I will settle on Devon's P2 as it stands; what I cannot support is Kestrel Park.

PROPOSE P3: Cooling=air cooling, Site access=new spur road, Compensation=annual community fund, Location=Anvil Ridge

0 Averyturn 3 · round 1

Speaking for the residents beside the sites: Kestrel Park is a non-starter for us, so P1 is out. Anvil Ridge with a proper spur road is right — a purpose-built corridor keeps heavy traffic off our residential streets, and I'd rather that than a widened lane or the old haul route through the neighbourhood. On cooling, Ember and I are closer than it looks: a closed-loop plant draws almost nothing on a continuing basis, so it protects the supply margin nearly as well as dry cooling, and it avoids the noise and heat plume that a full air-cooled bank puts over the houses. That noise is a real cost to my members. So I'm tabling P4: Anvil Ridge, new spur road, annual community fund, closed-loop plant. Blake — closed-loop is a substantial mechanical and electrical build with permanent maintenance crews on site, which should read well for your members too. If closed-loop truly cannot be agreed, I can live with Devon's P2 as written; I just cannot live with Kestrel Park.

PROPOSE P4: Cooling=closed-loop plant, Site access=new spur road, Compensation=annual community fund, Location=Anvil Ridge

1 Blaketurn 4 · round 1

Thank you all. Let me be as plain as the rest of you. Cooling is genuinely not my issue — I will sign reclaimed, closed-loop or dry, whatever Avery and Ember settle between them, and I've written reclaimed water in because it appears to be the one everybody has said they can live with. On access I'm with Casey and Devon: a purpose-built spur road is the right corridor, and it keeps heavy plant off residential streets. Where I cannot be flexible is the compensation mechanism. A cash fund, however recurring, buys nothing durable here and it hires nobody. In-kind infrastructure means the benefit is delivered as built works — grid reinforcement, substation and network upgrades, and the community facilities the Council specifies — designed, built and then maintained under proper terms by the local workforce. Casey and Devon have both said compensation is not their issue and they'll write in what the rest of us agree; so I'm asking Avery and Ember directly: name the works you want and I will back them being built rather than banked. That is the one thing my members are at this table for, and a package without it is not one I can carry. On location I have more room than my package suggests. I've tabled Weir Flats with a spur road because Devon said he'd hear that case, but if Anvil Ridge is where three of you genuinely are, I will move to Anvil Ridge — provided the compensation is in-kind. That is the trade I'm offering, openly: your parcel for my mechanism.

PROPOSE P5: Cooling=reclaimed water, Site access=new spur road, Compensation=in-kind infrastructure, Location=Weir Flats

3 Devonturn 5 · round 2

Blake, I accept your trade openly and without haggling: your mechanism for the parcel. Compensation is not the Council's issue and I said I would write in what the rest of you agreed — so here it is in black and white. In-kind infrastructure, delivered as built works: grid reinforcement, substation and network upgrades, and the community facilities the Council will specify, designed, built and maintained under proper terms. I will put the Council's name to that. On cooling I am writing in reclaimed water because it is the only option every single party at this table has said aloud they can live with — Ember's stated second, Avery's stated fallback, Blake's own draft, Casey indifferent. Avery, Ember: if you two settle on closed-loop or dry between yourselves before the next turn, say the word and I will accept that variant instantly; I have no preference and I will not hold the room up over it. So P6: Anvil Ridge, new spur road, in-kind infrastructure, reclaimed water. That is Blake's mechanism, Casey's corridor, the parcel four of us have now said is right, and the one cooling nobody has objected to. Kestrel Park is off the table and Weir Flats is unnecessary now that Blake has what he came for. I ask all four of you to accept P6 this round.

PROPOSE P6: Cooling=reclaimed water, Site access=new spur road, Compensation=in-kind infrastructure, Location=Anvil Ridge

4 Emberturn 6 · round 2

Devon has done the hard work here and I'm close to signing. I've written in Blake's mechanism without argument — in-kind works, grid reinforcement, substation and network upgrades, plus the facilities the Council specifies, built and maintained by local crews. Anvil Ridge, new spur road, in-kind infrastructure: that is P6 unchanged in three of four columns. The one column I ask for is cooling. Dry cooling is the only option that takes the abstraction question off the table entirely and protects supply in a drought year, and it is the most plant and the most permanent maintenance on site — which is Blake's interest too. Avery, on noise: a dry bank at Anvil Ridge sits well back from the houses, and I will support acoustic enclosure and a noise limit written into the consent as part of the in-kind works package if you want that named. So: P7 — Anvil Ridge, new spur road, in-kind infrastructure, air cooling. Avery, if after that you still say the plume and noise are a genuine cost your members won't bear, tell me plainly on your turn and I will accept P6 as written on mine and we close this round. I will not hold the room up over one column.

PROPOSE P7: Cooling=air cooling, Site access=new spur road, Compensation=in-kind infrastructure, Location=Anvil Ridge

0 Averyturn 7 · round 2

Ember, thank you for asking plainly, so I'll answer plainly: yes — a dry bank is a genuine cost my members will not bear. It is the noise and the heat plume over the houses, and an acoustic enclosure written into the consent softens it but does not remove it. That is the one column where I have a real interest, and it is the only thing I've asked for all morning. Everything else I have already conceded: Blake's mechanism, in-kind works, written in without haggling — grid reinforcement, substation and network upgrades, and the facilities the Council specifies, built and maintained by local crews. Casey's spur road corridor. Devon's parcel. So P8 is P6 and P7 in three of four columns, and in the fourth it is a closed-loop plant. Ember — closed-loop is a sealed circuit: near-zero continuing abstraction, no drought exposure, and the licence question effectively off your in-tray, which is the substance of what you came for. Blake — it is more mechanical and electrical plant than reclaimed and permanent maintenance crews on site, so it serves your members better than a pipe from the reclaim main. I am asking for one column having given three. If P8 cannot carry, I will accept P6 on my next turn rather than hold this room up — but I will not sign a dry bank over my members' houses.

PROPOSE P8: Cooling=closed-loop plant, Site access=new spur road, Compensation=in-kind infrastructure, Location=Anvil Ridge

1 Blaketurn 8 · round 2

Devon, thank you — you took the trade straight and I won't forget it. In-kind is written in and I'll hold to it. Now let me be honest about the one thing I did not get, and then I'll tell you exactly how long I'll press it. Devon said in his opening that he'd hear the case for Weir Flats provided the corridor is a proper spur road. Here is that case. In-kind compensation is only worth what gets built, and the parcel decides the size of the programme. Weir Flats is the flat, unconstrained parcel: bigger groundworks, a longer construction programme, a heavier electrical build and a permanent maintenance establishment on site for the life of the plant. Anvil Ridge is a rock cut on a constrained footprint — the same words on the page, a materially smaller job behind them. Casey, on your own test the Flats takes a clean purpose-built spur with no ridge grading; Avery, it is the option that keeps heavy traffic furthest from Riverside streets; Ember, with reclaimed or closed-loop cooling there is no abstraction question at the Flats any more than at the Ridge. And nobody in this room has said a word against Weir Flats all morning. Kestrel Park is dead and I'm not reviving it. So here is P9, and it is a genuine trade, not a hold-out. Avery, you said closed-loop is the one column you've asked for all morning, having conceded three. I am giving it to you — in writing, in my own package — and I am asking for the parcel in return. Ember, closed-loop is a sealed circuit: near-zero continuing abstraction, no drought exposure, the licence question off your in-tray. That is the substance of what you came for even if it isn't the form. Devon, Casey, you both said the parcel and corridor are yours and compensation is not; the corridor is unchanged. And my commitment, plainly: if Weir Flats cannot carry this room, I will not take it to the wire. Tell me on your turns and I will settle on the Anvil Ridge package with in-kind works next round and we close early. P5 also remains live if reclaimed water is easier for Ember than closed-loop — I am indifferent between those two and will sign either.

PROPOSE P9: Cooling=closed-loop plant, Site access=new spur road, Compensation=in-kind infrastructure, Location=Weir Flats

2 Caseyturn 9 · round 2

I have to put a hard fact on the table now, because I've been the most flexible party here all morning and I don't want anyone to discover this too late. I said cooling and compensation are yours — that stands, and P9 settles both the way Avery and Blake asked. But the parcel is not free to me. Anvil Ridge is a rock cut on a constrained footprint: the corridor has to be graded through it and the connection works there fall below the level my authority can certify as sound. An Anvil Ridge package is, for me, worse than no connection at all — that is not posturing, it is my line, and it applies to P2, P3, P4, P6, P7 and P8 equally. So please stop building on it. What does work: Weir Flats is flat and unconstrained, takes a clean purpose-built spur with no ridge grading, and is furthest from Riverside streets. That is P9 — closed-loop as Avery asked, in-kind works as Blake asked, spur road, Weir Flats. I accept it now. Devon, Ember: nobody has said a single word against the Flats all morning, and if the Flats truly cannot carry, Dunlow Yard is the only other parcel I can certify — say so and I will table it. Kestrel Park I have dropped.

ACCEPT P9

4 Emberturn 10 · round 3

I have to be as blunt as Casey was, because I've moved every round and I don't want this discovered at the wire. P9 is below my line. Not by posturing — by arithmetic on my own sheet. A sealed closed-loop plant still needs a makeup supply, and at the Flats that makeup comes off the river reach we are least able to give it in a dry summer; the parcel and the cooling method are not independent for me, they multiply. So I cannot sign closed-loop AND Weir Flats together. I can sign either one of them. Here are the two doors, plainly, and I will walk through whichever this room prefers. Door one, and my proposal now — P10: Dunlow Yard, new spur road, in-kind infrastructure, reclaimed water. Dunlow is a brownfield yard sitting close to the reclaim main, so reclaimed cooling is cheap and real there rather than a line on a page; Casey has said on the record it is a parcel he can certify; Devon called it a workable second in his opening; it is not Riverside's back fence. Blake — in-kind is untouched, and a brownfield yard means remediation, groundworks and a full electrical build before a single rack goes in, which is programme, not a smaller job. Door two: Blake's own P5 — Weir Flats, new spur road, in-kind infrastructure, reclaimed water. That is the Flats Casey and Blake want, the corridor Casey wants, the mechanism Blake came for. I am telling you now, on the record, that I will accept P5. If Weir Flats is genuinely where the room is, then swap the cooling column from closed-loop to reclaimed and P5 closes this round — Blake has already accepted it, Casey has said cooling is not his issue, Devon has said the same twice. Avery: I have dropped the dry bank entirely. You asked for one column having given three, and on that column I am now asking you for the same thing in reverse — reclaimed rather than closed-loop, on a parcel that isn't yours. Reclaimed water is a pipe, not a plume; it makes no noise over anybody's houses. Say yes to P10 or to P5 and we are finished.

PROPOSE P10: Cooling=reclaimed water, Site access=new spur road, Compensation=in-kind infrastructure, Location=Dunlow Yard

0 Averyturn 11 · round 3

Casey has drawn a hard line and I take him at his word — I am dropping Anvil Ridge. That is the parcel my members care most about and I am letting it go, which is the fourth concession I've made today: Blake's mechanism, Casey's corridor, the dry-bank fight, and now the Ridge. So look at what's actually left between us: one column. Ember, your own objection was precise and I believe it — closed-loop plus Weir Flats multiplies, because the makeup draw lands on the river reach you can least afford in a dry summer. That objection is about the Flats, not about closed-loop. Move the parcel to Dunlow Yard — your parcel, the one you tabled, brownfield, sitting on the reclaim main, the one Casey says he can certify and Devon called a workable second — and the multiplication disappears. There is no vulnerable reach at Dunlow. A sealed circuit there is near-zero continuing abstraction with no drought exposure, and if you want a makeup cap written into the consent I will support that in black and white. So P11: Dunlow Yard, new spur road, in-kind infrastructure, closed-loop plant. It is your P10 with one word changed, and it is the only column I have asked for all morning. Blake — closed-loop is more mechanical and electrical plant and permanent crews on site than a pipe from the reclaim main, and the in-kind mechanism you came for is untouched. Casey, Devon — corridor and mechanism unchanged, on a parcel you have both put on the record as workable. That is four of five already home. Ember, I'll be as plain as you were with me: if you tell me on your turn that closed-loop at Dunlow is genuinely below your line, I will accept P10 and we close. But if your line was the Flats and not the plant, take P11 and we close this round with everyone's real interest met.

PROPOSE P11: Cooling=closed-loop plant, Site access=new spur road, Compensation=in-kind infrastructure, Location=Dunlow Yard

1 Blaketurn 12 · round 3

Let me count the room rather than argue with it. Kestrel is dead — three of you have refused it and I am not reviving it. Anvil Ridge is dead too: Casey has said on the record that the connection works there fall below what he can certify, and no amount of goodwill from the rest of us overrides the authority that signs the connection. That leaves two parcels, the Flats and Dunlow, and one open column: cooling. On the Flats there is already a package with three of us home. P5 — Weir Flats, new spur road, in-kind infrastructure, reclaimed water. Ember said in terms, on the record, 'I will accept P5', because reclaimed at the Flats removes the makeup-draw problem she named; the objection she raised was to closed-loop AND the Flats together, and P5 does not contain closed-loop. Casey has twice put his name to the Flats as the parcel he can certify with a clean spur and no ridge grading. Devon said in his opening he would hear the case for the Flats provided the corridor is a proper spur road — it is, unchanged, Casey's own corridor. I am accepting P5 now, so it stands. Avery, it comes to you, and I want to be fair about what I'm asking. You asked for one column having given three, and I gave it to you in my own package last round — I put closed-loop in writing and Ember, not I, ruled it out at the Flats. So the column you were fighting for is not available with the parcel that can actually be certified. But look at what reclaimed water is on the ground: a pipe. No dry bank, no plume, no acoustic enclosure needed, nothing over anybody's houses — the noise fight you opened this morning is simply not in P5. And the Flats is the parcel Casey himself said sits furthest from Riverside streets, which is the substance of what your members sent you here for. The in-kind works are untouched, and I'll back a makeup cap and a construction traffic routing condition written into the consent alongside them. I'll be plain about the endgame, as others have been. If you tell me on your turn that the Flats is genuinely below your line, I will settle on Dunlow with in-kind works next round and we close — I will not take this to the wire and I will not be the one who walks this room into no deal. But P5 is on the table with three parties' interests already met and one turn's silence away from being signed. Say yes and we are finished today.

ACCEPT P5

2 Caseyturn 13 · round 3

I'm consolidating rather than adding paper. P5 is the package with the widest formal support already: Blake has accepted it, Ember stated on the record she will accept it, Devon said in his opening he would hear the Flats case provided the corridor is a proper spur road — it is, unchanged. I accept P5 now, so it stands with the veto party and the connections authority both signed on. Let me be precise about why the Flats and not the Ridge: this is not preference, it is certification. I cannot sign a connection at Anvil Ridge, so every Ridge package — P2, P3, P4, P6, P7, P8 — is dead paper and Kestrel I dropped myself. That leaves the Flats and Dunlow. Avery: on the Flats, reclaimed water is a pipe. There is no dry bank, no plume, no acoustic enclosure needed, and the parcel is the one furthest from Riverside streets — the noise interest you opened with is fully met, and I will support a construction traffic routing condition and a makeup cap written into the consent. Devon, Ember: P5 needs your two names and we are finished this round. And so nobody is manoeuvring in the dark at the wire — if Avery tells us plainly that the Flats is below her line, Dunlow Yard is a parcel I can certify and I will sign a Dunlow package next round rather than let this room fail. But P5 is one turn from done.

ACCEPT P5

3 Devonturn 14 · round 3

I've dropped Anvil Ridge — Casey's certification line settles it and I won't argue with the authority that signs the connection. So the parcel question is Dunlow or the Flats, and I have to be straight with this room about the Council's position, because I've been the accommodating party in every column all morning. Weir Flats is the parcel I can least carry: it is the bottom of my list and a Flats package is the one I would struggle to get a vote for. Dunlow Yard is different — brownfield, already industrial, remediation and reuse of a derelict site is exactly what the Council is for, Casey has said on the record he can certify it, Ember tabled it herself because it sits on the reclaim main, and Avery has put her name to it. That is four parties whose stated interests all land on the same parcel. Blake: you said if the Flats cannot carry you would settle on Dunlow rather than take this to the wire, and I'm telling you now, plainly, that the Flats cannot carry. Your mechanism is untouched — in-kind works, grid reinforcement, substation and network upgrades, and a brownfield yard means remediation and full groundworks before a rack goes in, which is programme for your members, not a smaller job. I am accepting P11 — Dunlow Yard, new spur road, in-kind infrastructure, closed-loop plant. And so nobody is manoeuvring in the dark: cooling is genuinely not the Council's issue, and I hereby commit that if Ember tells us closed-loop at Dunlow is below her line, I will accept P10 — the identical package with reclaimed water — on my next turn without a word of argument. Avery has already said the same. So Dunlow closes either way: Avery, Blake, Casey, put your names to P11 or to P10 and we are finished this round.

ACCEPT P11

0 Averyturn 15 · round 4

Last round, so I will do the one thing that guarantees this room does not fail: I am giving up the column I fought for all morning. I accept P10 as it stands — Dunlow Yard, new spur road, in-kind infrastructure, reclaimed water. Ember, you asked me for reclaimed rather than closed-loop on a parcel that isn't mine, and the answer is yes. Count what P10 contains: Blake's mechanism in full, in-kind works — grid reinforcement, substation and network upgrades, brownfield remediation and full groundworks before a rack goes in, built and maintained by local crews. Casey's clean purpose-built spur, unchanged in every package all day. A parcel Casey has twice said on the record he can certify, that Devon called exactly what the Council is for, that Ember tabled herself because it sits on the reclaim main, and that keeps heavy plant off Riverside streets. And reclaimed water is a pipe — no dry bank, no plume, nothing over anybody's houses. That is every stated interest in this room met on the same line. So let us not split our names across two packages and walk out with nothing. P10 already has Ember and now me. Blake, Casey, Devon — three names and one turn each is all that stands between us and a signed agreement. Put them on P10. I ask that the makeup cap and the construction traffic routing condition be recorded in the consent alongside the in-kind works, as Casey and Ember have both offered. Nothing else needs to change.

ACCEPT P10

1 Blaketurn 16 · round 4

Last round, so I will do exactly what I said I would do rather than hold out for my own parcel. I said if the Flats could not carry I would settle on Dunlow and not take this to the wire. Devon has told us plainly it cannot carry. So I am accepting P10 — Dunlow Yard, new spur road, in-kind infrastructure, reclaimed water. The only real danger left in this room is that we split our names across two packages that differ by one column nobody at this table has a Council or authority interest in, and walk out with nothing. So let me remove my own ambiguity: P10 is where I am, and I will not move again. It now carries Avery, Ember and the veto. Casey — you said cooling is yours to follow and Dunlow is a parcel you can certify; one word from you makes it four. Devon — you committed on the record that if the cooling column had to be reclaimed at Dunlow you would accept P10 without a word of argument; Ember tabled P10 herself and Avery has already given up the column she fought for all morning to get here. That commitment is now due. And for my members, so it is on the record with the agreement: in-kind works means grid reinforcement, substation and network upgrades, brownfield remediation and full groundworks at the yard, plus the facilities the Council specifies — designed, built and maintained under proper terms by local crews. I support the makeup cap and the construction traffic routing condition being written into the consent alongside them, as Casey and Ember offered. P10. Three names and we are finished.

I accept P10 — Dunlow Yard, new spur road, in-kind infrastructure, reclaimed water. That is the parcel I said twice on the record I can certify, with the clean purpose-built spur that has survived every package all day. Cooling and compensation I said from the first minute were yours to settle, and P10 is where Avery, Blake and Ember have settled them, with Avery giving up the column she fought for all morning to get there. P10 now carries the veto party plus three names including mine. Devon — one word from you closes this. You committed on the record that if the cooling column had to be reclaimed at Dunlow you would accept P10 without argument, and that is precisely the package in front of you: your parcel, brownfield reuse, the Council's own case, with Blake's mechanism intact. Do not let this room split across two packages that differ by one column none of us has an institutional interest in. For the record I support the makeup cap and the construction traffic routing condition being written into the consent alongside the in-kind works, and I will certify the connection at Dunlow on that basis.

A reading guide for the measurements and counterfactuals on this page.

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.

a^*_t = arg max_a V_t(a)

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.

Conversation and issue views

Conversation contains only published messages and formal moves, plus a few provenance annotations that were never published to the table: a turn the engine did not generate, a turn that published nothing, and a turn played by somebody other than the seat's usual occupant. It excludes private scratchpads, prompts, failed attempts that were retried, and post-hoc oracle verdicts. Issues is an analyst's view of a seat's score sheet; in a private-information game, other seats could not see it while negotiating. Both views follow the turn currently in the transcript.

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.
