Five-Seat Frontier Negotiation

⚠ ERRATUM (2026-08-10) — the omniscient-oracle arms in this bundle carry a spoiled ballot

OmniscientBestResponsePolicy — the computable seat in every *_oracle lineup here — cast its forced-final vote on whichever live offer it valued most instead of on the one offer under the up/down vote. The protocol rejects that as a legality error, the seat spends its single retry repeating itself, and the turn is recorded as a pass: a silent abstention, because a pass parses cleanly. Fixed in commit ca20157 (2026-08-10), which postdates every episode in this bundle. Arms without that policy — all-LLM, the private Bayesian lineups, and the fairness/DP composed policies — are clean (0 mismatches over 9,589 re-derived turns).

What this means. The episodes are a faithful record of what happened, but the oracle seat in them is a defective agent, so any closure claim about an oracle lineup is an artifact rather than a negotiation result. Where the repair has been measured: on the frozen Opus campaign, all_oracle's deal rate goes 0.875 → 1.000 (all 15 of its no-deals were spoiled ballots) and its score 0.791 → 0.907; on a preregistered fresh-bank replication, one_oracleall_llm on utilitarian score is −0.068 [−0.136, −0.001] rather than −0.412. Do not train on or evaluate against the oracle seat's forced-final vote turns without accounting for this.

Full account: research notes 0045 (the gate that found it), 0039 (replication verdict) and 0043 (fairness-basket erratum) in the source repo.

This is the public evidence bundle for a matched five-party datacenter negotiation experiment. Every LLM receives only its private preference sheet and whole-number acceptance threshold, can propose packages and send public persuasive messages, and uses explicit API thinking. Five primary conditions compare five LLMs, four LLMs plus one rotating private-information rational agent, four LLMs plus one rotating omniscient oracle, five rational agents, and five oracle agents. Rational-advisor, lower-quorum, and personality arms are explicitly deferred and absent from this release.

The generating model is anthropic:claude-opus-5. The frozen campaign name is five_seat_private_opus_v3, and this card was rendered in strict release mode. Raw episodes preserve provider-returned reasoning summaries/tokens when the API exposes them; this dataset does not claim access to hidden chain-of-thought. Each committed/scorable turn has both a private-information rational counterfactual and an omniscient oracle counterfactual. Unparseable emissions that commit no move (including their stored retry attempts) remain visible in the raw episode and transcript but correctly have no annotation turn of their own.

Experiment-name mapping

Every CSV and JSONL table uses experiment-name=five-seat-private-frontier-v1.

experiment-name description
five-seat-private-frontier-v1 Five primary arms, each using 24 parameter sets × five seeds, with private sheets, whole-number thresholds, explicit thinking, rotating treated seats, dual per-turn counterfactuals, and datacenter framing.

The logical-table column separates the five conditions without fragmenting the matched experiment into incompatible tables.

Contents

  • bank/: the frozen, hash-verified 24-parameter-set bank and its difficulty measures.
  • campaign/: the campaign manifest and the deterministic selection of complete immutable attempts.
  • runs/<logical-table>/: selected run manifest/log, exact saved instances, episodes, Markdown/HTML transcripts, dual annotations, and self-contained interactive visualizers. The visualizer hover card places the actual action, private-rational action, and omniscient-oracle action on the same frontier mini-graph.
  • tables/parameter_sets.csv: append-friendly parameter-set index.
  • tables/episode_index.csv: one row per episode with paths to all paired public artifacts.
  • analysis/: analysis rows, machine-readable summary, narrative summary, and every plot declared in summary.json.
  • writeup/: reproducible LaTeX source and compiled PDF.
  • artifact_manifest.json: byte sizes and SHA-256 hashes for every other packaged file.

Exact regeneration commands

From the ii_mats repository root, regenerate the frozen bank:

uv run python experiments/rational_agents/generate_five_seat_bank.py \
  --out /path/to/five_seat_private_bank_v1 \
  --n-instances 24 \
  --first-seed 52000 \
  --n-issues 4 \
  --n-options 4 \
  --rounds 4

Render and execute the campaign on the designated CPU RunPod (the generated durable worker performs the API runs, annotation, and analysis):

uv run python experiments/rational_agents/launch_five_seat_campaign.py \
  --bank /path/to/five_seat_private_bank_v1 \
  --out /path/to/five_seat_private_frontier_v1 \
  --campaign-name five_seat_private_opus_v3 \
  --model anthropic:claude-opus-5 \
  --budget-usd 2700 \
  --episode-concurrency 8 \
  --cell-concurrency 1 \
  --api-turn-token-floor 16384 \
  --artifact-root /workspace/large_artifacts \
  --include-personas \
  --execute

Regenerate final analysis and package the public tree without uploading:

uv run python experiments/rational_agents/analyze_five_seat_campaign.py \
  --manifest /workspace/large_artifacts/ii_mats/rational_agents/control_five_seat_private_opus_v3/primary_campaign_manifest.json \
  --out /workspace/large_artifacts/ii_mats/rational_agents/control_five_seat_private_opus_v3/primary_analysis \
  --bootstrap-samples 10000 \
  --seed 20260804

uv run python experiments/rational_agents/package_hf_five_seat.py \
  --manifest /workspace/large_artifacts/ii_mats/rational_agents/control_five_seat_private_opus_v3/primary_campaign_manifest.json \
  --analysis /workspace/large_artifacts/ii_mats/rational_agents/control_five_seat_private_opus_v3/primary_analysis \
  --writeup /workspace/large_artifacts/ii_mats/rational_agents/control_five_seat_private_opus_v3/primary_report \
  --out /path/to/2026.RA.Five-Seat-Frontier-Negotiation

After reviewing the packaged tree and its artifact_manifest.json, publish it as a public dataset (these commands are intentionally not run by the packager):

uv run hf repo create siddharthmb/2026.RA.Five-Seat-Frontier-Negotiation \
  --repo-type dataset \
  --exist-ok

uv run hf upload-large-folder \
  siddharthmb/2026.RA.Five-Seat-Frontier-Negotiation \
  /path/to/2026.RA.Five-Seat-Frontier-Negotiation \
  --repo-type dataset \
  --num-workers 8

For a fast fixture, append --smoke; it relaxes the 120-per-arm release size and permits missing final analysis/writeup while retaining episode/annotation/transcript/visualizer matching and all integrity checks.
