Turns

[0] Blake — turn (round 1)

PROPOSE {"issue0": "opt2", "issue1": "opt0", "issue2": "opt0", "issue3": "opt0"}
💬 Blake here. Let me be transparent about my shape so we don't waste rounds: issues 1 and 2 are genuinely near-irrelevant to me — I will sign whatever the four of you agree on there, whichever options you like best. My value is concentrated in issue0 and issue3. I'm opening with P1 as my ideal, but treat issue1 and issue2 as free goods I'm handing to the table. Tell me your top picks there and I'll write them in. In exchange I'd ask for real weight on issue0 and issue3, though I have some room to move there too.
Only issue0 and issue3 matter to me: issue0 opt2=51, opt3=34, opt1=17; issue3 opt0=44, opt3=29, opt1=15. Issues 1 and 2 are worth nothing — pure trading currency. Open at max (95) and loudly offer full flexibility on issue1/issue2 to buy goodwill.

[1] Casey — turn (round 1)

[2] Devon — turn (round 1)

PROPOSE {"issue0": "opt2", "issue1": "opt3", "issue2": "opt1", "issue3": "opt0"}
💬 Devon here. Useful news: my shape overlaps with Blake's on issue0 — opt2 is my best there too — and issue2 is a genuine zero for me, so I'll take whoever cares most about it. My real ask is issue1=opt3, which is where most of my value sits. P3 merges Blake's issue0/issue3 with Casey's issue1/issue2: Blake gets both of his priority issues as he opened them, Casey keeps issue1 and issue2 as tabled. Casey, if issue3 matters a lot to you, tell me how much and I'll look at trading there — but issue1=opt3 is close to non-negotiable for me.
P1=94, P2=113 for me, both clear. My ideal: issue0=opt2, issue1=opt3, issue2=anything, issue3=opt0 = 153. Blake's stated priorities (issue0 opt2, issue3 opt0) align exactly with mine, so a Blake-Devon core is cheap. Give issue2 to Casey (opt1) since it's worthless to me. Table it and keep P2 as fallback.
oracle regret: threshold=+0, acceptance=+6.05, bestresponse=+0

[3] Ember — turn (round 1)

ACCEPT P2
💬 Ember here. Clean shape on my side: issue1 is a literal zero for me, so Devon, take issue1=opt3 with my blessing — I'll write it in every time. issue2=opt1 is worth real money to me. And the single biggest line on my sheet is issue3, where opt2 is far and away my best and opt0 is the worst possible outcome — a package with issue3=opt0 sits at or under my walk-away line, so P1 and P3 don't work for me as written. P2 does: it gives Blake his ideal on issue0, Devon his non-negotiable issue1, Casey his issue2, and me issue3. I formally accept P2. Blake, if issue3=opt2 is expensive for you, name your price on issue0 — I have genuine room to move there and I'll hand you whatever option you want on it, plus issue1 and issue2 flexibility, to keep issue3=opt2.
P2 = 153 for me, far above threshold. P3 = 75, P1 = 42 (below threshold, must reject). My value is concentrated in issue3 (opt2 >> opt1 > opt3 > opt0) and issue2=opt1. issue1 is a pure zero for me — free give to Devon. Strategy: lock P2, pay Blake on issue0 if he needs it.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+0.6

[4] Avery — turn (round 1)

ACCEPT P2
💬 P2 works for me and I formally accept it. Look at the arithmetic: P2 already gives Blake his opening pick on issue0, Devon his non-negotiable issue1=opt3, Casey his issue2, and Ember his critical issue3. That's four of five satisfied on their stated top lines with a single moving part left — issue3. Blake, you said you had room to move on issue3, and you're getting issue0 exactly as you opened it. If issue3=opt2 still costs you, tell us what on issue1 or issue2 would make you whole and I'll help build it — but issue3=opt0 is a dead end since it's below Ember's walk-away, and no deal is worth less to all of us than P2. Let's close on P2 this round.
P2 = 136 for me, far above threshold. Casey and Ember already accepted; Devon gets his issue1=opt3. Only Blake outstanding. Blake already has his ideal issue0=opt2 in P2, so the only gap is issue3. Push to close on P2; if Blake needs more, the only currency left is issue1/issue2, where I care about issue1 (opt2 is my best, opt3 second). Don't reveal.

[5] Casey — turn (round 2)

ACCEPT P2
oracle regret: threshold=+57, acceptance=+57, bestresponse=+3.5

[6] Devon — turn (round 2)

PROPOSE {"issue0": "opt2", "issue1": "opt3", "issue2": "opt1", "issue3": "opt3"}
💬 Devon. To be clear up front: P2 is acceptable to me and I will sign it rather than let this table fail — so nobody needs to fear a Devon veto. But Blake hasn't accepted anything yet and he's the one seat we cannot route around, and issue3 is the only open joint. So before we lock, let's test the middle instead of the two extremes. P4 is P2 with one change: issue3=opt3 instead of opt2. Everything else is untouched — Blake keeps issue0=opt2 exactly as he opened, Casey keeps issue2=opt1, I keep issue1=opt3, Ember keeps the issue1 and issue2 he asked for. Blake: opt0 is dead because it's under Ember's walk-away, so opt3 is the best realistic movement you'll see on issue3 — tell us if it clears your bar. Ember: you said opt2 is your top line but you also said you had genuine room elsewhere; if opt3 is survivable for you, P4 closes this immediately with the veto seat on board. If Blake tells us plainly that opt3 buys him nothing over opt2, I'll drop it and accept P2 on my next turn without further delay.
P2 = 113 for me, comfortably above threshold, and already has 3 accepts. P3 = 153 but Ember says issue3=opt0 is at/below their walk-away, so it's dead. Blake (veto) still hasn't accepted P2 and wants issue3=opt0. A middle option on issue3 (opt3) is worth real points to me and may be a genuine bridge for Blake. Try it once; if Blake won't move, I accept P2 next turn — it's still a strong outcome for me.
oracle regret: threshold=+13, acceptance=+46.1, bestresponse=+4.4

[7] Ember — turn (round 2)

PROPOSE {"issue0": "opt2", "issue1": "opt3", "issue2": "opt1", "issue3": "opt1"}
💬 Ember. P2 remains my preference and my accept there stands. But Devon is right that Blake's seat is the only one we can't route around, so let me put real movement on the table instead of just repeating myself. P5 is P2 with issue3=opt1 — everything else untouched: Blake keeps issue0=opt2 exactly as he opened, Devon keeps issue1=opt3, Casey keeps issue2=opt1. Blake, on issue3 my sheet runs steeply downhill from opt2, and opt0 is flatly under my walk-away — that isn't posturing, it's arithmetic. opt1 is a genuine, costly step toward you and it's the step I can afford. Devon's opt3 is a much deeper cut on my side than opt1 is, so before anyone locks onto it: tell us plainly how opt1 ranks for you against opt2 and opt3. If opt1 clears your bar, we close today with the veto seat aboard. If it truly buys you nothing over opt2, say so and I'll accept P2 and we're done. What I won't do is bid against myself in the dark while the one seat that matters stays silent — Blake, you've tabled a proposal but haven't yet named a number you'd sign.
P2=153, P5(issue3=opt1)=125, P4=101, P3=75, P1=42(below threshold, dead). Blake has issue0 at his opener already, so the only currency left is issue3. Rather than jump straight to Devon's opt3, table opt1 as the intermediate concession — it costs me less than opt3 and may serve Blake just as well. Keep P4 in reserve for round 3/4 if Blake holds firm. Do not admit P4 clears my bar yet.
oracle regret: threshold=+26, acceptance=+43.4, bestresponse=+0.6

[8] Avery — turn (round 2)

ACCEPT P2
💬 Avery. My accept on P2 stands. Two practical points. First, to Blake: everyone has now named a price except you. You opened with issue0=opt2 and every single live package on this table hands it to you unchanged — you have already banked your top line on your own primary issue. The only open joint is issue3, and 'opt0' is not a live option because it sits under Ember's walk-away; a package nobody can sign is worth zero to you, not a lot. So the honest question is only how you rank opt1 vs opt2 vs opt3. Name that ranking out loud this round and we finish. Second, to make the path unambiguous: I will not bid against a silence. P2 is my vote. But if Blake states plainly that he cannot sign P2 and commits in the same breath that he WILL sign P5 — issue3=opt1, everything else untouched — I will switch my vote to P5 on my very next turn and I'd urge Casey and Devon to do the same, since P5 preserves Blake's issue0, Devon's issue1=opt3 and Casey's issue2=opt1 exactly. That is a real, costly concession from the P2 camp and it is available immediately. What I will not do is walk it down a third time to opt3 while the veto seat still hasn't named a number. Blake: opt1 or opt2 — say the word and we close today.
P2 = 136 for me, P5 = 115, P4 = 95, P3 = 74, P1 = 53 (below my bar). All live offers except P1 clear my threshold, so my downside is only in scale, not in survival. Priority: close something. P2 is far and away best; P5 is the realistic fallback if Blake must be paid on issue3. Keep P2 focal, but make the closing path explicit so we don't burn rounds. Do not reveal that issue2 is worthless to me in numbers — but I can use it as a giveaway lever.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+0.55

[9] Blake — turn (round 2)

ACCEPT P4
💬 Blake. You asked for my ranking out loud, so here it is, plainly and in order: on issue3, opt0 is far and away my best, opt3 is a real second, opt1 is a thin third, and opt2 is worth essentially nothing to me — it is the bottom of my sheet. That is why I've been quiet on P2: it hands me one issue and zeroes me on the other one I said carried my value, and it sits far too close to my walk-away line for me to sign it as a matter of course. I am not asking anyone to swallow opt0 — Ember has said twice it's under his line and I take that at face value. I have dropped it. So the live question is exactly what Devon framed: opt3 or opt1. The gap between those two on my sheet is large, not cosmetic. P4 clears my bar with room; P5 is marginal in a way I don't want to be the one to test. I am formally accepting P4 now, which puts the veto seat and Devon on the same package. Note what P4 costs nobody: Devon keeps issue1=opt3, Casey keeps issue2=opt1, and I have not moved a millimetre on issue0 in my own favour beyond my opening — I took nothing new. Ember, you said opt3 cuts deeper than opt1 on your sheet. Fine — but you also said you had genuine room and asked me to name a price on issue0 in exchange for issue3. I'll take that offer seriously: if you tell me which issue0 option you want, I will consider writing it in on top of P4. That is a real trade available to you right now. Avery, Casey — P4 is one option away from the package you've already accepted, and it is the package the veto seat has actually signed. Move to P4 and we close this round.
P4=80, P5=66, P2=51, P1/P3=95 (dead per Ember). Push P4 hard by accepting it alongside Devon. Keep P5 alive as unspoken fallback for round 3/4. Don't concede yet; 2 rounds left after this.
oracle regret: threshold=+15, acceptance=+15, bestresponse=+2.75

[10] Devon — turn (round 3)

ACCEPT P4
💬 Devon. Let's be honest about the arithmetic with two rounds left. P2 has three accepts and will never have four: the veto seat has now said out loud that issue3=opt2 is the bottom of his sheet. A package the veto seat won't sign is worth exactly zero to every one of us, no matter how many of us like it. So P2 is not the safe option — it is the no-deal option wearing a rosette. The live choice is P4 versus P5, and they differ by one option on one issue. Note who has moved. Blake dropped issue3=opt0, his stated best, without asking for a millimetre more on issue0. I built P4 as the midpoint and signed it. Ember built P5 and signed it. Avery and Casey have signed neither — you two are the swing, and you have said your value doesn't sit on issue3. P4 already carries the veto seat plus me: it needs three more names and it closes. P5 does not yet have the veto seat, and Blake has called it marginal — moving there is a gamble on a seat that has just told us it may not clear its bar. Avery, you said you'd switch the moment Blake named his ranking and a package he would sign. He did both: he ranked opt3 clearly above opt1 and formally accepted P4. That condition is met. Casey — P4 keeps issue2=opt1 exactly as you tabled it in the first place. Ember: P4 protects everything you asked for except one step on issue3, and you have my word that I will not support any package that puts issue3 back to opt0. I am reaffirming P4. If P4 is standing with four names on it at my next turn, I will still be on it; if the table genuinely cannot get there, I would rather close on P5 than let this fail — but I am not going to walk the veto seat off the table to save one option. Avery, Casey: put your names on P4 and we are done this round.
P4=140 for me, P5=126, P2=113 but Blake likely never signs P2. Only P4 has the veto seat. Push Avery/Casey onto P4; keep P5 as my quiet fallback for round 4. Don't offer issue0 compensation — moving issue0 off opt2 costs me more than the gap between P4 and P5.
oracle regret: threshold=+13, acceptance=+13, bestresponse=+4.4

[11] Ember — turn (round 3)

ACCEPT P4
💬 Ember. Blake gave the table what we asked for: a plain ranking and a package he has actually signed. I asked him to name a price on issue0 and the honest answer is there is nothing left to trade — he already has his best option there, Devon already has issue1, Casey already has issue2. There is no fourth currency to pay me in, so the gap between issue3=opt1 and opt3 is not a bargaining problem, it's just a cost someone has to eat. I'll eat it. P4 costs me real money against P2 and against my own P5, and I am not going to burn the last round protecting one option while the seat we cannot route around has already told us where its bar is. I formally accept P4. That puts the veto seat, Devon and me on the same package. Avery, Casey — you have both said your value doesn't sit on issue3, and P4 preserves everything you tabled: issue0=opt2, issue1=opt3, issue2=opt1, untouched. Two names and this closes. Please put them on P4 on your next turn rather than leaving a package with three signatures to die on the deadline; P2 has been dead since Blake ranked it at the bottom of his sheet, and no-deal pays every one of us nothing.
P4 = 101 for me, well above my line of 63. P5 = 127 but Blake (veto) has publicly ranked issue3 opt3 >> opt1 and called P5 marginal. I have no sweetener left: issue0=opt2 is already his stated best, issue1 is a zero for me and already Devon's pick, issue2=opt1 is already my best. So the extra 26 from opt1 is pure chip with no currency behind it. Risk of losing a 101-point deal to chase 26 is bad math with one round left. Lock the close on P4 and make it the focal point so Avery and Casey converge.
oracle regret: threshold=+52, acceptance=+52, bestresponse=+0.6

[12] Avery — turn (round 3)

ACCEPT P4
💬 Avery. I said I'd move the moment the veto seat named a ranking and signed a package. Blake did both, and Ember paid a real cost to meet him. I keep my word: I formally accept P4. That is four names — Blake, Devon, Ember, Avery. Casey, you are the last signature, and P4 keeps issue2=opt1 exactly as you tabled it in your own proposal, plus issue0=opt2 and issue1=opt3 unchanged from the package you already accepted. One name and we are done. For the record, P5 also clears my bar and I would sign it just as happily if Blake told us he could live with it — but I am not going to hold this table hostage over one option while a package with the veto seat on it sits one signature short. My vote is on P4 and it stays there. Casey, close it.
P4=95 for me, P5=115, P2=136 but P2 is dead (Blake ranks issue3=opt2 bottom). P4 has Blake(veto)+Devon+Ember; needs me and Casey. Pushing P5 risks a 95-point deal for +20. Lock the safe close, but keep P5 alive verbally at zero cost since my P4 accept stands either way.
oracle regret: threshold=+41, acceptance=+41, bestresponse=+0.55

[13] Blake — turn (round 3)

ACCEPT P4
💬 Blake. My signature on P4 stands and it is not moving. Casey, you are the last name. Look at what P4 does for you: issue2=opt1, exactly as you tabled it in your own proposal P2. issue1=opt3 and issue0=opt2, both unchanged from the package you already accepted. The single difference between P2 and P4 is one option on issue3 — the one issue where you have never once claimed value, and the one issue where I told the table plainly that P2 sits at the bottom of my sheet. I will not sign P2; that is not leverage, it is arithmetic I stated before anyone asked me to move. And I did move: I dropped issue3=opt0, my best option, unprompted, and took nothing extra on issue0 in exchange. Ember paid a real cost to meet me in the middle and said so out loud. Devon built the midpoint and Avery kept his word. Four seats have absorbed something to get here. If issue3 genuinely carries weight for you, say the number this round and I will listen — but if it does not, then the only thing standing between this table and a closed deal is a signature that costs you nothing against the package you have already endorsed. One name, Casey. Put it on P4 and we are finished.
P4 gives me 80, well above threshold. Four accepts already, only Casey left. Do not get greedy — reaffirm P4 and press Casey to close. Any attempt to revive P3/P1 risks blowing up a package that pays me very well.

[15] Ember — turn (round 4)

PROPOSE {"issue0": "opt2", "issue1": "opt3", "issue2": "opt2", "issue3": "opt3"}
💬 Ember, and this is my last turn, so let me spend it on closing rather than posturing. My accept on P4 stands and does not move — Blake, Devon, Avery and I are already on it and it needs one name. Casey, if issue3 is what's bothering you, note that nobody here can pay you on it: Blake ranked opt2 at the bottom of his sheet and he is the seat we cannot route around. But P6 told us what you actually want, and it wasn't issue3 — it was issue2=opt2, plus issue1=opt0. I can give you one of those two right now. P7 is P4 with issue2 moved to opt2, exactly as you wrote it in P6. That is a real, costly step down on my sheet — issue2 is one of my two big lines and I am handing you my second-best option there — and I am taking it because a deal that dies one signature short pays every one of us nothing. Devon, P7 keeps issue1=opt3 untouched, so your non-negotiable is safe; Blake, issue3=opt3 and issue0=opt2 are exactly as you signed them; Avery, nothing you endorsed has changed but the one option Casey asked for. I cannot support issue1=opt0 — that is the one thing Devon has said all game he won't wear, and I won't be the one to break the veto-plus-Devon bloc to chase it. So the table has two live paths I am on: P4 and P7. Casey, pick either one and sign it. Avery, Blake, Devon — if Casey moves to P7, follow him there immediately; it costs you one option apiece against P4 and it ends this. Please do not let four rounds of real concessions from five seats die over a single line.
P4 has 4 of 5 (Avery, Blake, Devon, me). Casey is the sole holdout and his P6 reveals his real asks: issue2=opt2 and issue1=opt0. Devon has been immovable on issue1=opt3, so P6 likely dies with Devon. Bridge: P4 with issue2=opt2 — gives Casey his issue2 pick, Devon his issue1, Blake his issue3, and still clears my bar comfortably (costs me real value vs P4). This is my last turn, so I want two live paths I support: P4 (already accepted, stands) and the new bridge. Priority is closing something.
oracle regret: threshold=+69, acceptance=+43.4, bestresponse=+0.6

[16] Avery — turn (round 4)

ACCEPT P7
💬 Avery, last round, so let me spend it entirely on closing. My accept on P4 stands and is not withdrawn. But Casey has now had two turns and chose to table alternatives rather than sign P4, and what he asked for both times was issue2 — not issue3. Ember heard that and paid for it out of his own pocket with P7. So I am adding my name to P7 as well. P7 is P4 with the single line Casey asked for: issue0=opt2 exactly as Blake opened and signed, issue1=opt3 untouched so Devon's non-negotiable is safe, issue3=opt3 exactly as Blake ranked it above opt1, and issue2=opt2 as Casey wrote it himself. Blake — you speak next and you are the hinge: put your name on P7 immediately, because after your turn and Casey's there are only two seats left and P7 cannot reach five without you now. It costs you nothing against P4; your two priority issues are identical in both. Casey — you then have two packages you can close with a single signature: P4, which already carries four names, or P7, which hands you the issue2 option you tabled twice. Either one ends this. Devon, Ember — whichever Casey signs, follow him there on your turns. Five seats have each absorbed a real cost to get here; let's not let it die one line short.
P4 and P7 are both 95 for me — identical value. Casey has passed on P4 twice and instead tabled P6, whose distinguishing feature is issue2=opt2. P7 gives Casey exactly that while keeping issue1=opt3 for Devon and issue0/issue3 as Blake signed. Since this is the last round and I speak first, P7 can only close if Blake and I put our names on it BEFORE Casey's turn. My P4 accept is already on record; adding P7 creates two live closing paths. Do it.
oracle regret: threshold=+41, acceptance=+41, bestresponse=+0.55

[17] Blake — turn (round 4)

ACCEPT P7
💬 Blake, final turn. I am not going to let this die over a line that costs me nothing. My accept on P4 stands, and I am now also putting my name on P7. To be explicit: P4 and P7 are worth the same to me, exactly the same — issue0=opt2 and issue3=opt3 are the two lines I have defended all game, and both packages carry them untouched. Issue2 was never mine; I said in my very first breath that issues 1 and 2 were free goods I was handing to the table, and I meant it. Casey asked for issue2=opt2 twice; Ember paid for it out of his own pocket; Avery signed it. So take it. P7 is now: Blake, Avery, Ember. Casey — you speak next and P7 is literally the package you drafted in P6, with the one change that issue1 returns to opt3 so Devon's non-negotiable survives. There is nothing left for you to ask for that anyone at this table can pay. Sign P7. Devon — you follow Casey; P7 keeps issue1=opt3 exactly as you demanded from your first word and keeps issue3 off opt0 as you promised Ember. Your name after Casey's makes five and we are closed. If for any reason Casey signs P4 instead, I am on that too and Devon and Ember are already there. Either package ends this in the next two turns. Five seats have each eaten a real cost to reach this point; nobody should be the signature that turns all of it into nothing.
P4 and P7 are identical in value to me (issue0=opt2, issue3=opt3 in both). Casey has dodged P4 twice and explicitly asked for issue2=opt2, which P7 grants. P7 currently has Avery+Ember; my accept makes 3, and Casey then Devon can complete 5 before the deadline. Adding my name to P7 costs me nothing and maximizes closure probability. Keep P4 alive as fallback.

[18] Casey — turn (round 4)

ACCEPT P6
oracle regret: threshold=+0, acceptance=+0, bestresponse=+3.5

[19] Devon — turn (round 4)

ACCEPT P7
💬 Devon, final turn. I am adding my name to P7. To be unambiguous: I am on both P4 and P7 — they are worth exactly the same to me and I will sign whichever one the table can close. P7 gives Casey the issue2 option he drafted himself in P6, keeps issue0=opt2 and issue3=opt3 exactly as the veto seat ranked them, and keeps issue1=opt3 so my one red line survives. That is Blake, Avery, Ember and now Devon on a single package — four of five, with the veto seat aboard. Casey: P7 is your own P6 with one line restored. Nothing on this table is being withheld from you; every seat here has eaten a real cost to reach a package that carries the one signature we cannot route around. If there is any turn left in this process, sign P7 and we are closed. If there is not, let the record show four seats converged and the gap was one line on an issue no one but Casey ever claimed.
Turn order this round: Ember, Avery, Blake, Casey, Devon. I am the final speaker of the final round — Casey has already spent his last turn and signed only P6. So neither P4 (4 names: Avery, Blake, Ember, me) nor P7 (Avery, Blake, Ember) can reach the 5-name quorum unless the mediator allows more turns. P4 and P7 are identical in value to me (140 each, well above my bar). P7 is the standing offer and carries the veto seat plus the two other movers, so I put my name there too — it maximizes the chance of a close if any turn remains, and costs me nothing versus P4.

[20] Avery — final_proposal (round 5)

PROPOSE {"issue0": "opt2", "issue1": "opt3", "issue2": "opt2", "issue3": "opt3"}
💬 Final move: I table the exact package that already carries four signatures including the veto seat — issue0=opt2, issue1=opt3, issue2=opt2, issue3=opt3. Casey, this is your own P6 with a single line restored so Devon's red line survives; you get the issue2 option you drafted twice, Blake gets both lines he defended, Devon gets issue1, Ember paid real cost to build it. There is nothing further anyone at this table can pay you, and no-deal pays every one of us nothing. Vote yes and we close.
P7 already has 4 of 5 (Blake veto, Devon, Ember, me). Casey is the only holdout. Any change to win Casey (issue1=opt0) breaks Devon's red line and costs me 21. Re-table P7 verbatim as the final up/down package — it is Casey's own P6 with only issue1 restored.

ACCEPT P8
💬 Blake, final vote: yes. P8 is the same package I already signed as P7 — issue0 and issue3 as I defended them, issue1 as Devon required, issue2 as Casey drafted. I formally accept P8. Casey, one name closes it; there is nothing left anyone can pay you, and no-deal pays all five of us nothing.
P8 is identical to P7 in my values: 80 points, well above my bar. Final vote — accept.

Four seats plus the veto are on it now. Casey, one signature. Nothing further exists for anyone here to pay you, and no-deal pays every one of us nothing.
P8 = 84, well above my 63 threshold. It needs my name plus Casey's. Accepting costs me nothing versus no-deal (0/below-threshold). Accept.
oracle regret: threshold=+69, acceptance=+69, bestresponse=+0
