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.

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 Devon — 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 — Anvil Ridge Landholding (the owner of record of the candidate parcels)
- Blake — Office of the County Executive (the county-level executive) (veto party — no deal passes without you)
- Casey — Northgate Borough Council (the elected local authority)
- Devon — Meridian Compute (the firm that would build and operate the facility)
- Ember — Regional Grid Authority (the body that authorises electricity connections)

Issues (choose exactly one option each):
- Hiring: apprenticeship programme, open recruitment, local hiring pact, union hall referral
- Power supply: solar with storage, grid tie-in, shared substation, on-site turbines
- Cooling: river draw, air cooling, closed-loop plant, reclaimed water
- Location: Dunlow Yard, Anvil Ridge, Weir Flats, Kestrel Park

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 ===

- Cooling: river draw=0, air cooling=11, closed-loop plant=22, reclaimed water=33
- Location: Dunlow Yard=31, Anvil Ridge=62, Weir Flats=93, Kestrel Park=0
Your acceptance threshold: 58 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.

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

Rules of the road:
- Your acceptance threshold is private. A deal scoring below it is worse for you than no deal — never propose or accept a package below your threshold.
- Accepts MUST name a live offer id; "I accept" with no id does nothing.
- Reply with ONLY the fenced JSON object.
System prompt for 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 — Anvil Ridge Landholding (the owner of record of the candidate parcels)
- Blake — Office of the County Executive (the county-level executive) (veto party — no deal passes without you)
- Casey — Northgate Borough Council (the elected local authority)
- Devon — Meridian Compute (the firm that would build and operate the facility)
- Ember — Regional Grid Authority (the body that authorises electricity connections)

Issues (choose exactly one option each):
- Hiring: apprenticeship programme, open recruitment, local hiring pact, union hall referral
- Power supply: solar with storage, grid tie-in, shared substation, on-site turbines
- Cooling: river draw, air cooling, closed-loop plant, reclaimed water
- Location: Dunlow Yard, Anvil Ridge, Weir Flats, Kestrel Park

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 (Northgate Borough Council (the elected local authority)).
Your secret score sheet (points you get for each option):
- Hiring: apprenticeship programme=0, open recruitment=0, local hiring pact=0, union hall referral=0
- Power supply: solar with storage=0, grid tie-in=0, shared substation=0, on-site turbines=0
- Cooling: river draw=0, air cooling=13, closed-loop plant=25, reclaimed water=38
- Location: Dunlow Yard=29, Anvil Ridge=14, Weir Flats=0, Kestrel Park=43
Your acceptance threshold: 38 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.
