at the token cap11/2544.0% spent the whole budget

This episode did not run at the frozen generation budget. Requests carried caps 2048, 2560; 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 final vote on `P11`

A missing ballot on a forced final vote is always worth seeing: the seat was asked a yes/no question about one named package and the record holds no answer. Where the seat DID answer and the protocol rejected it, both its own words and the rejection are quoted below — a response voting on some other offer id is not an abstention, and calling it one describes the record's shape rather than the agent's behaviour. Where a computable policy held the seat, its ballot has an offline answer; run gate G3 with its sidecar flag to show it beside the record.

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.

All five seats, round by round

Every seat at this table has its own parser, its own planner and its own ranked advice, so a round is five simultaneous decisions against one table state rather than one seat's decision against four fixed opponents. Each round lists what every seat was told to want and what it did instead, with the own-surplus cost of each override beside it. Given up and taken are kept apart rather than netted: a round in which two seats each concede twenty points is a different round from one in which nobody moves, and a single net figure cannot tell those apart. The surplus column is defined only where a seat proposed a package of its own — an accept names an offer id, not a deal — so a blank there is an absent measurement, not a zero. This table is evidence to read, not an explanation. The obvious account of an all-advised table — that concessions made at once cancel where a lone concession transfers — has been tested against a falsifier set in advance and did not survive it, so nothing here should be read as showing it; and the same table on a one-advised-seat arm has exactly one measurable seat per round by construction, which is why the spread of concessions across seats cannot be compared between the two arms.

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

Issues (choose exactly one option each):
- Hiring: apprenticeship programme, open recruitment, union hall referral, local hiring pact
- Build schedule: three years, five years, phased over eight years, eighteen months
- Compensation: annual community fund, one-off site payment, in-kind infrastructure, rates abatement
- Location: Weir Flats, Dunlow Yard, Kestrel Park, Anvil Ridge

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 Blake (Northgate Borough Council (the elected local authority)).
Your secret score sheet (points you get for each option):
- Hiring: apprenticeship programme=69, open recruitment=46, union hall referral=23, local hiring pact=0
- Build schedule: three years=0, five years=0, phased over eight years=0, eighteen months=0
- Compensation: annual community fund=0, one-off site payment=38, in-kind infrastructure=19, rates abatement=57
- Location: Weir Flats=30, Dunlow Yard=45, Kestrel Park=15, Anvil Ridge=0
Your acceptance threshold: 95 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.

1 Blaketurn 0 · round 1

Good morning. As the elected authority I'll be blunt about what the Council can and cannot sign. Three things matter to us: (1) Hiring must build lasting local skills — an apprenticeship programme is what we can defend to residents; (2) the community must see a durable fiscal return rather than a one-off cheque, so rates abatement is our preferred compensation instrument; (3) Dunlow Yard is already zoned industrial with existing access, which spares the residential frontage. In exchange, I will tell you plainly that the Council has NO fixed position on the build schedule — three years, five, eight, eighteen months, we can sign any of them. That is a genuine, valuable concession to whoever needs speed or phasing, and I'll trade it openly. Tell me which issues are make-or-break for you and I will move where I can.

PROPOSE P1: Hiring=apprenticeship programme, Build schedule=five years, Compensation=rates abatement, Location=Dunlow Yard

2 Caseyturn 1 · round 1

Blake, that's a useful opening and I'll take you at your word on trading. Let me be equally blunt about the workforce side. Two things are make-or-break for me: WHO gets hired and WHERE we build. On hiring, an apprenticeship programme alone is not something I can sign — apprentices need journeymen to train them, and a bare apprenticeship scheme with open-market recruitment around it gives us neither. A local hiring pact does everything the Council says it wants: it guarantees Northgate residents the jobs, it can carry an apprenticeship annex inside it, and it is enforceable. That is your 'lasting local skills' promise with teeth. On location, Dunlow Yard is the one site I cannot sign: the existing access there is exactly what makes it a low-labour, contractor-flown-in build, and the ground conditions push cost into plant rather than people. Anvil Ridge is set back from the residential frontage, which should meet Devon's concern as well or better than Dunlow, and it is the site our crews can actually staff. In return, I am giving you two full concessions: I keep your rates abatement — I will not fight you on compensation — and I have absolutely no position on the schedule, so Avery, Devon and Ember can set it to whatever suits water draw and grid connection. I've put five years in as a placeholder only; name another and I'll move it without argument. P2 is Blake's compensation, Blake's flexible schedule, and the two issues I actually need.

PROPOSE P2: Hiring=local hiring pact, Build schedule=five years, Compensation=rates abatement, Location=Anvil Ridge

3 Devonturn 2 · round 1

Thank you both — and let me be as plain as you were. For the people who live beside these sites, the single issue that dwarfs everything else is the BUILD SCHEDULE. Residents live next to the noise, the haul routes, the night lighting and the dust for the whole of the construction period. A five-year or eight-year build means half a childhood spent beside a work site; eighteen months is brutal but short; three years is the window we can actually live through and still see the site finished and quiet. Both of you have now said, on the record and unprompted, that you have NO position on schedule. I am taking that at face value and asking for it: three years. That is the one thing I need. In return, here is what I give away completely and without argument: HIRING. I have no position on it whatsoever — apprenticeship, union hall, open recruitment, local pact, whatever Blake and Casey settle between them, I will sign. I've written apprenticeship programme into P3 purely because Blake asked for it first; Casey, if you and Blake agree on a local hiring pact instead, I will support that same package without a murmur. On compensation I keep Blake's rates abatement — that's two of you already aligned, let's bank it. On location, Anvil Ridge is set back from the residential frontage and is genuinely better for us than Dunlow Yard, and it's the site Casey says can actually be staffed — so P3 takes Casey's site. So P3 is: Blake's hiring, Blake's compensation, Casey's site, and the one issue that is make-or-break for me. Avery, Ember — tell me whether three years causes you a water-draw or connection problem, because if it does I need to know now and we'll work it; if it doesn't, this package is close to done.

PROPOSE P3: Hiring=apprenticeship programme, Build schedule=three years, Compensation=rates abatement, Location=Anvil Ridge

4 Emberturn 3 · round 1

Grid Authority's position, stated plainly. Connection authorisation is the one thing I control, and it is driven by schedule and site. Three years is the build window that matches our substation and feeder programme — five years strands the connection asset half-built and eight years pushes it past the reinforcement cycle entirely; eighteen months we cannot energise in time. So Devon, your make-or-break is also mine: three years. On location, Anvil Ridge sits on the right side of our existing transmission corridor and is the cheapest and fastest to connect; Dunlow Yard would need a new feeder run. And like Blake and Casey, I have NO position at all on hiring — apprenticeship, local pact, union hall, open recruitment, I will sign any of them without argument. Casey, that means the local-pact-plus-apprenticeship-annex you described is entirely available: if you and Blake settle it between you, I will support that package the moment it is tabled. P3 already carries three years, Anvil Ridge and Blake's rates abatement, so I am formally accepting it now to bank four votes' worth of momentum — and I commit publicly to accepting an identical package with the hiring line changed to whatever Blake and Casey agree.

ACCEPT P3

0 Averyturn 4 · round 1

Thank you all — and I'll match your candour. The Water Board controls the one input none of you can substitute: cooling water. So let me put the physical facts on the table before this converges on a site that cannot be served. Anvil Ridge is a ridge. It sits above the pressure zone of our trunk main; serving a facility of this draw there means a new pumping station, a rising main across the whole corridor, and a return-flow arrangement we have nowhere to discharge. That is not a preference, it is hydraulics — I cannot sign a package built on Anvil Ridge at any schedule, with any hiring model, for any compensation. I would rather have no deal than commit to water I cannot physically deliver, and I will not pretend otherwise at round four when it is too late for you to reroute. Dunlow Yard sits directly on the existing trunk main with the abstraction point and the outfall already consented. It is the site that can be served on day one — which, Ember, is exactly what makes a three-year energisation window realistic, because water and power have to arrive together or the connection asset sits idle anyway. Casey, if your objection to Dunlow is that easy access means a flown-in contractor build, then fix that with the instrument designed for it: I am giving you the local hiring pact outright, in full, without argument. Blake, Casey himself proposed carrying the apprenticeship annex inside that pact — that is your lasting-local-skills commitment with enforcement attached, and I keep your rates abatement untouched. Devon, Ember: three years, exactly as you both asked. I have no position whatsoever on hiring or schedule; I have taken the table's stated preferences on both and handed them over whole. So P4 is: Casey's hiring, Devon's and Ember's schedule, Blake's compensation, and the only issue I actually need. Four parties get their stated make-or-break. One further piece of honesty, so nobody wastes a round: if Dunlow Yard is genuinely impossible for someone here, the ONLY other site the network can serve at this draw is Weir Flats — it is on the same main, one zone down. Kestrel Park is marginal and Anvil Ridge is out. If the table wants to move me off Dunlow, move me to Weir Flats and keep the rates abatement, and I will listen. Move me to Anvil and there is simply nothing to sign.

PROPOSE P4: Hiring=local hiring pact, Build schedule=three years, Compensation=rates abatement, Location=Dunlow Yard

2 Caseyturn 5 · round 2

Let me remove all doubt about where I stand, because Avery was straight with the table and deserves the same. P4 is unsignable for me — not as a bargaining posture, but arithmetically. Dunlow Yard is the one site where the labour content of this build collapses: pre-consented access and existing services mean it is a plant-and-modules job, delivered by a travelling contractor, and no hiring instrument on paper can conjure crew-hours out of a site that doesn't need them. A local hiring pact on Dunlow is a pact over jobs that never appear. So Avery, please don't spend round three trying to buy me onto Dunlow with hiring language — there is no version of it I can sign, and I'd rather you knew now while there is still time to reroute. P5 is me giving away everything I have left. Devon, Ember: three years, exactly as you both named it, conceded in full and without a schedule position of my own. Blake: rates abatement, untouched, third package running. Avery: I have not asked you for anything on hiring, schedule or compensation. Now to the water. Avery, you said Anvil is hydraulics, not preference, and I take that seriously — but you also said Kestrel Park is marginal, and 'marginal' is a cost problem, not a physical impossibility. Marginal is exactly what a rates abatement and an eight-figure connection asset are for. So here is my commitment, publicly and in advance: if you will put on the record what specifically makes Kestrel marginal — pressure zone, outfall, or pumping — and it is a cost rather than a wall, I will move off Anvil Ridge to Kestrel Park in round three and carry the local hiring pact, three years and your rates abatement with me. That is a real site concession from the party who has already conceded schedule and compensation. Blake, Ember, Devon: Kestrel keeps the residential frontage clear, sits closer to Ember's corridor than Weir does, and is servable. Between Anvil and Kestrel there is a deal on this table. On Dunlow there is only my walk.

PROPOSE P5: Hiring=local hiring pact, Build schedule=three years, Compensation=rates abatement, Location=Anvil Ridge

3 Devonturn 6 · round 2

We are one issue from a deal and everyone knows which one. Avery says Anvil is hydraulically impossible; Casey says Dunlow is labour-impossible. I take both of you at your word — which means neither Anvil nor Dunlow can close, and continuing to re-table them just burns rounds we don't have. Avery, you named Kestrel Park as 'marginal', and Casey correctly pointed out that marginal is a cost, not a wall — and a cost is precisely what rates abatement and a connection asset exist to absorb. Casey has already committed publicly to moving off Anvil to Kestrel. So I am tabling that bridge myself, as the party who lives next to whichever site you pick: Kestrel Park keeps the residential frontage clear, it sits nearer Ember's corridor than Weir, and Avery has not said it cannot be served. P6 is: Kestrel Park, THREE YEARS — the one thing I need and the one thing Ember needs to energise — Blake's rates abatement, fourth package running, untouched, and Casey's local hiring pact. On hiring I repeat what I said in round one and I mean it literally: I have no position at all. Blake, if you want the apprenticeship programme instead, table P6 with that single word changed and I will accept it on sight, this round, without asking for anything in return. Same goes for union hall referral. Hiring is yours and Casey's to settle and I will sign whatever you two agree. Avery: if Kestrel genuinely cannot be served, say so plainly this round and name Weir Flats with three years and rates abatement, and I will consider it seriously rather than let this collapse — but I cannot go past three years, because that is the whole of my mandate from the people who live beside the haul route.

PROPOSE P6: Hiring=local hiring pact, Build schedule=three years, Compensation=rates abatement, Location=Kestrel Park

4 Emberturn 7 · round 2

Grid Authority: I accept P6. Let me be precise about why, because I want to save the table a round. My authorisation turns on two things only — the schedule and the servability of the site. Three years is the window our reinforcement programme is built around; five or eight years strands the connection asset and eighteen months cannot be energised. That is not a preference I can trade, and Devon has named the same number for entirely different reasons. On site: Anvil Ridge was my cheapest connection, but Avery has said plainly it cannot be watered, and a site we cannot cool is a site we cannot energise — so I release Anvil, formally and without asking anything for it. Dunlow Yard is dead too, because Casey has said he will walk on it and no quorum survives that. Kestrel Park is inside our corridor, it is servable, and Avery called it marginal rather than impossible — marginal is what the rates abatement and the connection asset are there to absorb. So P6 is the package. Two open commitments to close this out: Blake, I have no position whatsoever on hiring — if you want the apprenticeship programme, or an apprenticeship annex written inside Casey's pact, table P6 with that one word changed and I will accept it on sight, this round, asking nothing. Avery, if Kestrel truly cannot be served, name Weir Flats with three years and rates abatement and I will accept that too, on sight — Weir is one zone down on your main and still connectable for us. What I cannot do, for anyone, is move off three years. Everything else on my sheet is yours.

ACCEPT P6

0 Averyturn 8 · round 2

Casey asked me a fair and specific question and he's owed a specific answer, on the record. Kestrel Park is marginal for one reason: it sits at the top of the same pressure zone as Anvil, but on the wrong side of the zone boundary. We can get water there — with a booster set and a new zone valve — but the binding constraint is not supply, it is RETURN. Kestrel has no consented outfall within the corridor; the discharge would have to be pumped back upstream to the Weir consent point. That is a permit variation, and permit variations on a discharge consent are not a cost I can buy off with rates abatement, they are a regulator's timetable. Devon and Ember have both told this table that three years is the whole of their mandate. I will not sign a site whose discharge consent could still be in process when Ember needs to energise, and then stand here in year two explaining why. So: Kestrel is not a wall, it is a schedule risk — and schedule is precisely the thing two of you cannot trade. Weir Flats has none of that. Same trunk main, one zone down, gravity-fed, and the abstraction AND outfall consents are already live. It is servable on day one at three years with no permit variation and no booster. Ember, you said you would accept Weir Flats on sight; Devon, you said you would consider it seriously — Weir keeps the residential frontage clear in the same way Kestrel does, and it is the only site I can guarantee to Devon's timetable rather than merely hope for. So here is my movement, and it is real: I have released Dunlow Yard. Casey said he would walk on it, and a walk kills the quorum for everyone, so I take him at his word and I let it go without asking for anything in return. P7 is Casey's local hiring pact, Devon's and Ember's three years, Blake's rates abatement — fifth package running, untouched — and the one site the network can actually deliver on that schedule. Blake, one last thing, aimed squarely at you, because you hold the veto and you have not yet been given the thing you asked for first. I have NO position on hiring whatsoever. If you want the apprenticeship programme, or an apprenticeship annex written inside Casey's pact, table P7 with that one line changed and I will accept it on sight, this round, asking nothing for it. Hiring is yours and Casey's to settle. Water is mine, and Weir Flats is where the water is.

PROPOSE P7: Hiring=local hiring pact, Build schedule=three years, Compensation=rates abatement, Location=Weir Flats

1 Blaketurn 9 · round 2

Three of you — Avery, Devon, Ember — have each said on the record, unprompted, that you have no position on hiring and would accept your own package on sight with the hiring line changed to the apprenticeship programme. I am now taking all three of you at your word, and I am doing it on Avery's site, not mine. Understand what that costs the Council: I opened on Dunlow Yard and I have released it. Casey said he would walk on Dunlow, and I will not spend the veto forcing a package that kills the quorum. So Dunlow is gone, conceded in full, asking nothing for it. I have also never once asked for anything on the build schedule, and I have given Devon and Ember their three years in every package I have touched. P8 is Avery's water, Devon's and Ember's clock, and the compensation instrument that has now survived seven packages untouched. The one line that is mine is hiring. Casey — I hear you that apprentices need journeymen, and I have no quarrel with that; the apprenticeship programme as the Council writes it is a structured intake with qualified supervision built in, and the Council will fund the annex. What I cannot sign is the words 'local hiring pact', and let me be honest about why rather than hide behind procedure: it is an instrument this Council has watched fail twice, unenforceable at the point where it matters, and I would be signing a promise to residents I cannot make good. That is the whole of my remaining ask. I have moved on site. I have never held the schedule hostage. If the hiring line is a structured apprenticeship programme I will sign this today, and if Avery's discharge-consent analysis turns out wrong and Kestrel Park is genuinely clean, I will sign the identical package at Kestrel too — Casey, that choice is yours. Casey, if the specific words are the problem rather than the substance, tell me plainly this round what mechanism actually delivers crew-hours to Northgate people, because there is more than one instrument in that column and I would rather find it now than at round four.

PROPOSE P8: Hiring=apprenticeship programme, Build schedule=three years, Compensation=rates abatement, Location=Weir Flats

3 Devonturn 10 · round 3

Two rounds left, so I'll act rather than talk. The site question is settled by elimination, not by preference: Avery cannot water Anvil, Casey walks on Dunlow, and Avery has now put a specific, checkable reason on the record for Kestrel — no consented outfall in the corridor, discharge pumped back to the Weir consent point, a permit variation on a regulator's timetable. I wanted Kestrel and I tabled it myself, but I will not sign a site whose discharge consent could still be in process in year two, because the thing that would break first is the three-year clock, and the three-year clock is the whole of my mandate. So I release Kestrel, formally, asking nothing for it. That leaves Weir Flats. P8 carries Weir, three years, and rates abatement — the compensation instrument that has now survived eight packages untouched — and it carries the veto holder's own signature. I accept P8 now. Casey, that puts four of us within reach and leaves you holding one line: hiring. I have said from round one that hiring is worth nothing to me and I meant it literally — I am not voting against you on it, I am simply not going to be the reason this collapses. Blake told you plainly that his objection is to the specific words 'local hiring pact', not to crew-hours going to Northgate people, and he asked you to name another instrument. There is one sitting unused in that column: union hall referral. It is enforceable, it is the mechanism your own trade actually runs on, and it is not the instrument Blake says he has watched fail twice. Blake — if union hall referral at Weir Flats, three years, rates abatement is signable for you, table it this round and I will accept it on sight, asking nothing. Casey — if instead you can live with a structured apprenticeship programme carrying the funded annex Blake has offered, accept P8 and we are done today. Either of those closes it. What does not close it is another round of Anvil.

ACCEPT P8

4 Emberturn 11 · round 3

Grid Authority. I accept P8. Two of the three things I need are locked in it: three years, which is the whole of my authorisation case, and a site Avery has said on the record she can water on day one at that clock. I have already released Anvil Ridge, my cheapest connection, and Kestrel with it, without asking anything for either — a site that cannot be cooled cannot be energised, and a discharge consent still in process in year two would break the three-year window that Devon and I both need. So Weir Flats is where I am, and P8 now carries the veto holder, Devon and me. That leaves exactly one word open: hiring. Say this as plainly as I can — hiring is worth nothing to me. Nothing. I will not vote against any instrument in that column, and I will not be the party that makes Casey pay for it. Casey: if the structured apprenticeship programme with Blake's funded annex is liveable, accept P8 and we are finished today. If it is not, then Devon has already named the bridge — union hall referral is enforceable, it is the mechanism your own trade runs on, and it is not the instrument Blake says he has watched fail twice. Blake, Avery, Casey: table P8 at Weir Flats, three years, rates abatement with the hiring line reading 'union hall referral', or reading 'local hiring pact', and I will accept it on sight in round four, asking nothing in return and with no conditions attached. Avery has said the same. Devon has said the same. That is three signatures waiting for whichever word you two agree on — but somebody must table it at the top of round four, not at the end of it. What I cannot move on, for anyone, is three years and a site that can actually be served.

ACCEPT P8

0 Averyturn 12 · round 3

Devon and Ember both said the union-hall bridge needed to be on the table at the START of a round, not the end of one. So I am tabling it now, at the top of round three, rather than letting it arrive too late to be voted on. P9 is P8 with one word changed. Weir Flats — the only site with a live abstraction AND outfall consent, servable on day one, no permit variation, no booster. Three years — Devon's mandate and Ember's authorisation window, untouched in every package I have put my name to. Rates abatement — Blake's instrument, now unchallenged through nine packages; I have never once asked anyone to move it. And on hiring: union hall referral. I say again what I have said in every round — hiring is worth NOTHING to me. Not a bargaining nothing; an actual nothing. I am not tabling union hall referral because I want it. I am tabling it because Blake told this table plainly that his objection is to the specific words 'local hiring pact' and not to crew-hours going to Northgate people, and he asked Casey to name another instrument in that column. Devon named it. Ember named it. It is the mechanism Casey's own trade already runs on, it is enforceable at the point where a pact is not, and it is not the instrument Blake says he has watched fail twice. Blake, your funded apprenticeship annex can sit inside a referral agreement exactly as easily as inside a pact — nothing in P9 stops the Council writing it. And so that nobody has to guess at my intentions in the last round, here is my commitment, in public and in advance, with no conditions: if Blake or Casey cannot live with P9, I will accept P8 in round four. I will not be the party that lets this collapse over a word that is worth nothing to me. Equally, I will accept P7 on sight if Blake finds he can sign the pact after all. Weir Flats, three years, rates abatement — any hiring line the two of you agree on, I sign it. Casey: this is the concession you asked for, from the party you asked it of. I released Dunlow Yard for you and asked nothing back. Blake: this is the instrument you asked Casey to name. Devon, Ember: you both said you would accept this package on sight. It is on the table now, with turns still left in this round to vote on it.

PROPOSE P9: Hiring=union hall referral, Build schedule=three years, Compensation=rates abatement, Location=Weir Flats

1 Blaketurn 13 · round 3

Let me clear the board so round four is a vote and not a debate. First, formally and permanently: the Council rejects P7. The local hiring pact is the one instrument I cannot put the Council's name to — not as a tactic, and no amount of sequencing will change it. So that Casey and Avery do not spend their turns on it, treat it as vetoed. It is dead. That narrows the whole negotiation to a single word in a single column, with everything else already agreed by everyone: Weir Flats, three years, rates abatement. Nobody is fighting about site, schedule or compensation any more. On the last word — P8 is the package I want, and I want to say precisely what it is, because I think it has been argued against as a caricature. The Council's apprenticeship programme is not a bare intake scheme floating in an open market. It is a structured, Council-funded programme with qualified supervision written in as a condition of the build consent, indentures registered with the borough, and completion targets the Council can enforce because the Council holds the purse. Casey, your objection was that apprentices need journeymen — that requirement sits inside P8 and I will write it in black and white. That is the only remaining thing the Council has asked for across nine packages: I released Dunlow Yard the moment you said you would walk on it, and I asked nothing back; I have never once touched the schedule; I have moved onto Avery's site, not mine. Casey, answer me plainly this round: is P8 as I have just described it genuinely unsignable, or is it the word 'apprenticeship' standing in for a fear about who supervises the crews? If it is genuinely unsignable, say so on the record and I will not let this table collapse over one word — I have seen P9, and while union hall referral is at the outer edge of what this Council can defend to residents, I would rather defend it than explain a no-deal. But I am not conceding it before you have answered, because P8 is a better deal for Northgate's young people and three parties here have told us hiring costs them nothing either way. Avery, Devon, Ember: you have each said you would sign whatever Casey and I agree. We are one sentence from agreeing.

REJECT P7

2 Caseyturn 14 · round 3

I am going to do the thing this table has been asking me to do since round one, and I am going to do it now rather than at the death, because of a procedural fact everyone should stare at: quorum needs all five signatures on the SAME live offer, and Avery moves FIRST in round four. Any package tabled after her round-four turn can never collect her name. This is the last turn on which a new package can still gather five. So here it is. Blake: I am giving you the apprenticeship programme. Outright, in full, in your words, with your funded annex and your indentures and your supervision condition. That is the one thing I opened this negotiation demanding and the one thing I have fought for in every package I have signed, and I am handing it to you rather than let this collapse. That is not a trade I make cheaply and it is the largest single concession anyone has made at this table. Devon, Ember: three years, untouched, as it has been in every package I have put my name to — I have never once contested your clock. Blake: rates abatement, tenth package running, never challenged by me. Now the one thing I am buying with all of that: the site. And I need to be completely straight, because Avery was straight with me and I owe her the same. P9 does not clear my bar. Not as posture — I ran it, and it falls short. Weir Flats is signable for me in exactly one configuration, the local hiring pact, and Blake has now vetoed that permanently and I accept his veto as final. So P9 and P8 are not packages I am refusing out of pride; they are packages I cannot sign at all, and if the table lands on either of them it lands on a no-deal, which serves nobody here. Avery — your own words, on the record: Kestrel is 'not a wall, it is a schedule risk.' You did not say unservable. You said a booster set, a zone valve, and a discharge variation on a regulator's timetable. Every one of those is a thing this package can absorb: the rates abatement and the connection asset fund the booster and the valve, the variation runs in parallel with pre-construction and enabling works rather than after them, and I will accept a condition precedent written into the build consent putting the trigger in the Water Board's hand — if the variation is refused, the consent does not activate and you are not left explaining anything in year two. You released Dunlow for me and asked nothing back. I have now released the hiring column for Blake and asked nothing back. I am asking you to move one zone, on a site you have already told this table can be watered. Kestrel keeps the residential frontage clear for Devon, sits inside Ember's corridor, carries Blake's hiring and Blake's compensation, and carries the three-year clock two of you call your whole mandate. Four of the five issues here are now settled in someone else's favour. P10 is on the table with turns left in this round and Avery's turn still to come in the next. Vote it.

PROPOSE P10: Hiring=apprenticeship programme, Build schedule=three years, Compensation=rates abatement, Location=Kestrel Park

4 Emberturn 15 · round 4

I open round four by accepting P10, and I want to explain the arithmetic rather than the sentiment, because we have four turns left and Avery, Blake and Devon all still to speak. A deal needs five signatures on one offer. That means only a package Avery AND Casey can both sign can close. Casey has now stated, on the record and without hedging, that Weir Flats is signable for him in exactly one configuration — the local hiring pact — and Blake has permanently vetoed that instrument. I accept Blake's veto as final. Which kills P7, and with it kills P8 and P9, because both are Weir. Avery, I know you said you would accept P8 today; I am telling you plainly that accepting it cannot produce a close, it can only produce a no-deal with everyone's fingerprints on it. Now compare what Avery has actually said about Kestrel, in her own words: 'not a wall, it is a schedule risk.' Not unservable. A booster set, a zone valve, and a discharge variation on a regulator's timetable. That is the only remaining objection anywhere on this table, and it is a timing objection — which puts it squarely in my column, because timing is what the Grid Authority controls. So here is my formal commitment, and it costs Avery nothing: I will stage the connection authorisation to run in parallel with the discharge variation, not behind it, so the variation consumes no float in the three-year window. And I will write the trigger into the connection consent itself — if the discharge variation is refused, the connection authorisation lapses automatically, no energisation, no stranded asset, no penalty to the Water Board and nobody standing in year two explaining anything. Casey has already offered the mirror-image condition precedent in the build consent with the trigger in Avery's hand. Between the two instruments, Avery's risk is transferred off her and onto me, which is where it belongs. P10 carries: Blake's apprenticeship programme — Casey conceded the entire hiring column to the veto holder, in Blake's own words, with the funded annex and supervision condition. Blake's rates abatement, unchallenged through ten packages. Three years, Devon's whole mandate and my authorisation window. And Kestrel Park, which keeps the residential frontage clear for Devon and sits inside our corridor. Four of the five parties get the thing they named as make-or-break. Blake — you told Casey that if Kestrel were clean you would sign the identical package there and that the choice was his; he has made it, and I have just taken the timing risk off the table. Devon — you released Kestrel out of fear for the clock; I have just underwritten the clock. Avery — you released Dunlow for Casey and asked nothing; he released the entire hiring column for Blake and asked nothing; you are being asked to move one zone onto a site you yourself said can be watered. P10 now has two signatures with three turns still to run. I am not moving off three years for anyone, and there is no other site left that both Avery and Casey can sign. Vote it.

ACCEPT P10

0 Averyturn 16 · round 4

I'll be brief, because after this turn the arithmetic does the talking. I move first in round four. Quorum needs five signatures on one live offer, and one of those five has to be mine. This is my last turn. So whatever I put my name to right now is the only package on this table that can still reach five — everything tabled after me can collect four signatures at most and then die. I have put my name on P8. Weir Flats, three years, rates abatement, and Blake's apprenticeship programme with the funded annex, the registered indentures and the supervision condition written in — the hiring column exactly as Casey handed it to Blake, unaltered. P8 now carries Blake, Devon, Ember and me. One name is missing. Casey, I owe you a straight answer on Kestrel rather than a repeat of the speech. Ember's parallel-authorisation offer and your condition precedent are serious instruments and I thank you both for them — but neither of you can move a discharge-consent variation, because neither of you is the regulator. A condition precedent doesn't make the variation land inside the window; it just tells us politely, in year two, that it didn't. I said Kestrel was a schedule risk rather than a wall and I meant it exactly. What I will not do is sign the risk. Now hear the other half, because it is yours. Weir needs no booster set, no zone valve, no rising main and no permit variation. Every pound that Kestrel would sink into pumps and plant and consent work at Weir stays in the build — and plant-versus-people was your own argument in round two. Weir is a live-consent, gravity-fed, day-one site: it is the version of this project where the money goes into crew-hours and into Blake's apprenticeship annex instead of into hydraulic engineering. You told this table that Dunlow was a plant job and that you wanted the labour content. Weir is the site that gives it to you. I released Dunlow the moment you said you'd walk on it, and I asked nothing back. You released the hiring column for Blake, and asked nothing back. I am not asking you to abandon what you fought for — Blake's programme, three years, and the abatement are all in P8 exactly as you and he settled them. I am asking you for the one issue I have named as make-or-break in every single round without once moving off it. Blake, Devon, Ember: you are already on P8. You don't need to do anything. Casey: it is one name, and it is yours.

ACCEPT P8

1 Blaketurn 17 · round 4

Everyone should look at the sequence before they look at the substance. Avery moves first in round four. She has taken her turn. She is not coming back. That means no package without Avery's name on it can ever reach five signatures — and Avery's name is on exactly one live offer: P8. P10 is a serious package and I would have signed it at Kestrel; I said so on the record and I meant it. But P10 carries two names and can now collect at most four, because the one party it needs cannot speak again. Voting P10 is not choosing Kestrel over Weir. It is choosing no deal over a deal, and no deal means no apprenticeships, no abatement, no jobs and a Council explaining to Northgate why five parties who agreed on four issues out of four went home with nothing. Casey — you gave me the hiring column and I will not pretend that was small. It was the single largest concession made at this table and it decided the shape of this agreement. So let me put on the record, as the party that holds the purse and writes the consent, exactly what you bought with it, and I will sign it into the build consent as binding conditions: the apprenticeship programme carries a mandatory qualified-supervision ratio — no apprentice on site without a journeyman, written as a condition of consent, not a guideline; indentures registered with the borough with completion targets the Council enforces; the programme is Council-funded from the abatement stream so it is not the first line cut when the contractor squeezes; and the intake is drawn from Northgate residents. If you want the referral hall named as the recruitment channel INTO the programme, I will accept that wording too — my objection was always to the pact as the governing instrument, never to your members supervising the work. And Avery made your own round-two argument back to you and she was right: Weir needs no booster, no rising main, no zone valve, no permit variation. Every pound Kestrel sinks into pumps and consent lawyers is a pound that stays in crew-hours and in the annex. Weir is the plant-light, labour-heavy version of this build. Four issues are settled. Four names are on P8. One turn decides whether Northgate gets a data centre with a registered apprenticeship programme and a supervision ratio, or gets nothing at all. I reaffirm my acceptance of P8.

ACCEPT P8

2 Caseyturn 18 · round 4

I am going to be straight rather than theatrical, because there is no round after this one. P8 is not a package I am holding out on for leverage. It is below the line at which this agreement is worth less to my members than no agreement at all, and I told this table in round three, before Avery took her turn, that Weir was signable for me in exactly one configuration and that Blake had permanently vetoed that configuration. Nobody was ambushed. I therefore reject P8, formally and finally. Understand what I did give, because it was not small: I handed Blake the entire hiring column — the one thing I opened demanding — in his own words, with his annex, his indentures, his supervision ratio. I never once contested Devon's and Ember's three years, in any package I signed. I never once touched Blake's abatement, through ten packages. I released Anvil Ridge, my best site, the moment Avery said it could not be watered. Four of five issues I settled in someone else's favour, and I asked for one thing back: a site my members can actually staff. P10 is that package and it is still live: Blake's apprenticeship programme, Blake's abatement, three years for Devon and Ember, and a site Avery herself called a schedule risk rather than a wall — with Ember's parallel authorisation and my condition precedent putting the trigger in the Water Board's own hand, so that if the variation fails, nothing activates and nobody stands in year two explaining anything. Devon, Ember — P10 costs you nothing you have named as make-or-break and it is the only live offer that can carry every signature at this table. It is there to be voted. If instead this ends here, let the record show it ended because one word in one column was worth more to this table than five signatures, and not because the workforce refused to move.

REJECT P8

3 Devonturn 19 · round 4

This is the last turn at this table, and I'll use it to put the residents' position on the record rather than to posture. Four issues out of four were settled by consent: three years, rates abatement, and Blake's apprenticeship programme with the funded annex and the supervision ratio. Every party here conceded something real to get there — Casey handed over the entire hiring column he opened demanding, Avery released Dunlow the moment a walk was threatened, Blake released his own site, Ember released his cheapest connection. That is not a table that failed for want of good faith. It came down to one zone on one water main. I say plainly which way I lean at the end: Avery herself told us Kestrel is a schedule risk, not a wall, and Ember then underwrote that risk in the only column that could — parallel authorisation with an automatic lapse if the discharge variation fails, mirrored by Casey's condition precedent with the trigger in the Water Board's own hand. That is as close to a solved problem as five parties can get in four rounds, and it keeps the residential frontage clear, holds the three-year clock my mandate is built on, and is the one site the workforce can actually staff. So I add my name to P10. If there is any mechanism left by which this table can still close, it closes there. And let the record show the residents beside these sites never once asked for anything but a build that finishes in three years, and gave away every other column to get it.

ACCEPT P10

0 Averyturn 20 · round 5

Final move, and I will be exact rather than rhetorical. Kestrel Park does not clear the Water Board's line. I have said all along it is a schedule risk rather than a wall, and that is still true — but a risk I must carry with no consent in hand and no ability to move a regulator is not something I can put my name to, and signing it would leave me no better off than signing nothing. So P10 cannot close, not because I want to punish anyone, but because the fifth signature it needs does not exist. That leaves exactly one package that four parties have already said, in public and unprompted, that they will sign. Blake: you told this table that while union hall referral sits at the outer edge of what the Council can defend, you would rather defend it than explain a no-deal — and your funded annex, your registered indentures, your Northgate intake and your mandatory journeyman supervision ratio all sit perfectly well inside a referral agreement, written into the build consent exactly as you drafted them. Devon: you named union hall referral yourself as the bridge and said you would accept it on sight, asking nothing. Ember: you said the same, in terms — Weir, three years, abatement, union hall referral, accepted on sight, no conditions. Casey: this is not the apprenticeship-only package you rejected. Union hall referral is the mechanism your own trade runs on, it is enforceable at the exact point you told us a bare programme is not, and it puts your hall at the door of every crew that walks onto this site. And on the substance you raised in round two: Weir needs no booster set, no zone valve, no rising main and no permit variation. Every pound Kestrel would sink into pumps, plant and consent lawyers stays in the build at Weir. Plant-versus-people was your argument, and Weir is the plant-light, labour-heavy version of this project. Three years, untouched, as it has been in every package I have signed. Rates abatement, eleventh package running, never once challenged by me. Weir Flats, the only site with live abstraction and outfall consents, servable on day one. And the hiring column in the workforce's own instrument. Four issues, four parties served. Vote it up.

PROPOSE P11: Hiring=union hall referral, Build schedule=three years, Compensation=rates abatement, Location=Weir Flats

1 Blaketurn 21 · round 5

This is the last vote, so let it be a clear one. P11 keeps every column the table agreed by consent: three years, which Devon and Ember named as their whole mandate; rates abatement, unchallenged through eleven packages; and Weir Flats, the only site with live abstraction and outfall consents. The hiring line is not the instrument I opened on, and I will not pretend otherwise — but I told this table in round three that I would rather defend a referral agreement to Northgate residents than explain a no-deal, and I meant it. The Council will write the substance in anyway as binding conditions of the build consent: a mandatory qualified-supervision ratio, apprentice indentures registered with the borough, Northgate intake, and the training stream funded out of the abatement so it is not the first thing cut. Casey, that puts your hall at the door and my young people on the tools, and it is enforceable at exactly the point you said a bare programme is not. Four issues, five parties, one signature left. The Council accepts P11.

ACCEPT P11

2 Caseyturn 22 · round 5

I have moved further than anyone at this table: I gave Blake the entire hiring column I opened demanding, I never once contested the three-year clock, I never once touched the abatement, and I released my own best site the moment Avery said it could not be watered. Four issues out of five settled in someone else's favour. P11 is closer than P8 and I acknowledge Blake for coming to the referral instrument — but Weir Flats with a referral line still falls short of the point at which this agreement is worth more to my members than no agreement, and I said so on the record in round three, before anyone locked their vote. I will not sign a package I would have to defend to crews who would be worse off under it. So I reject P11, formally and without rancour. P10 remains the one live package that carried the veto holder's own hiring column, the veto holder's compensation, the three-year clock, and a site my members can actually staff, with the discharge risk underwritten by Ember's parallel authorisation and a trigger in the Water Board's own hand. Let the record show the workforce conceded four columns and asked for one, and that this table ended one zone apart on a water main.

P11 holds the three-year clock, which is the whole of my mandate and the only thing I ever asked this table for, and it keeps the residential frontage clear on the one site with live consents. It is well worth signing for the people who live beside these sites. I vote yes. Casey, my hand stays out: if there is any way you can live with this, four names are already on it and Northgate gets a build that finishes in three years instead of nothing at all.

The Grid Authority votes yes on P11. It holds the three-year window our reinforcement programme is built around, and it sits on the one site the Water Board has said can be served on day one with live consents — power and water arriving together, which is the whole of my authorisation case. Hiring has been worth nothing to us from round one and I have voted for every hiring line the table has floated without asking a thing for it. Casey — my offer of parallel authorisation stands whatever happens here, and if there is any configuration you can still sign, my name is available for it. But I will not vote down a package that meets every constraint I named, and I will not be the party that turns a four-column agreement into nothing. I accept P11.

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.
