Rational-Agent Divergence DPO Pairs

This is the corrected p4_dataset_v2 preference dataset built from the validity-gated P2 negotiation campaign. Each row pairs the model's stored per-turn rendered prompt and verbatim action with an executable best-response-oracle action rendered in the same wire format.

All 12,761 rows contain the required experiment-name field, set to p4-divergence-dpo-v2.

Splits

Split Rows Purpose
train 5,533 Episode-level training split
eval 649 Episode-level validation split
holdout_model 3,866 OLMo model holdout
holdout_instance 2,713 Game-2 instance holdout
Total 12,761 Pairwise overlaps are zero

The upload includes stats.json, build logs, v0/v1 diff audits, and a SHA-256 artifact_manifest.json. The original prompts have 100% stored-view coverage. Chosen actions were parser-validated by the dataset build.

Row schema

  • experiment-name: stable append-friendly experiment identifier.
  • prompt: the exact stored rendered participant view at the divergent turn.
  • chosen: best-response-oracle action rendered in the model's action format; the full form may include a rationale synthesized only from oracle numbers.
  • rejected: the model's original emission verbatim.
  • meta: model, episode, game, arm, scaffold, information condition, turn, regret, flags, split criteria, and provenance fields.

Important use restrictions and findings

The full dataset is an audit/research corpus, not a recommendation to train on every row. The preregistered pilot training subset was:

own model AND phase == "turn" AND info == "full" AND scaffold == "canonical"

Three hazards were deliberately excluded from the pilot mix:

  1. forced-final-vote labels could choose a different offer from the explicit vote target;
  2. PRIVATE labels use an omniscient oracle with score sheets unavailable to the acting model;
  3. scaffolded emissions confound training with the prompt intervention.

The paired action-only control showed that 95.5% of the naive chosen/rejected separability came from oracle-rationale prose, not the decision. A single-game preliminary outcome gain did not replicate on three unseen games. The final pilot conclusion is negative: these data do not establish that divergence-localized DPO improves negotiation outcomes out of distribution.

The v2 rebuild corrects proposer-seat best-response pricing and a replay annotation contamination bug. It is bit-identical to v1 in prompt/chosen/rejected/weight/regret across all 12,761 pairs; only an auxiliary flag changed. The included diff files document the complete audit chain.

Exact regeneration command

From experiments/rational_agents/ in the ii_mats repository:

UV_LINK_MODE=copy uv run python p4_dataset.py \
  --manifest p2_selected_manifest.json \
  --out-dir /nlp/scr/siddharth/ii_mats/rational_agents/p4_dataset_v2 \
  --annotations-name annotations_v1 \
  --provenance-note "Corrected v2; see metadata/build.log for the full audit note." \

  --eval-frac 0.1 \
  --split-seed 20260727 \
  --weight-cap 5.0 \
  --weight-scope per_game \
  --n-examples 3

metadata/build.log preserves the literal original command, including its long-form correction/audit note. metadata/stats.json preserves resolved counts, deciles, source revisions, split membership, filtering census, and parser checks.
