Data dictionary

Shared identifiers and design

run_id: synthetic stable identifier derived from condition metadata; it does not encode a source path or timestamp.
game: game identifier (ro_public_good or fischer_2004).
mechanism: ORS mechanism (vcm, sccm, ccm) where applicable.
prompt_modifier: prompt treatment, such as none, remove_worked_examples, or coalition_example.
model_slug, model, model_label: anonymized publication labels for the served model variant. These identify models, not people.
seed, repetition, chain_id, generation, player: experimental random seed/repetition and within-trajectory indices.
treatment: restart/continuation treatment label from the experiment.
fixed_count, fixed_policy, fixed_placement: fixed-player condition; empty values denote a baseline condition.

ORS decision-level columns

choice: parser-normalized choice code.
contribution_1, threshold_1, contribution_2, threshold_2: submitted SCCM/CCM offers. The second pair is empty for VCM/SCCM as appropriate.
implemented_contribution: contribution implemented by the mechanism.
total_contribution, total_contributors, payoff: group total, contributor count, and individual payoff.
contribution_share, normalized_welfare: contribution and welfare as a proportion of the maximum.
conditional_mechanism_use, activated_conditional_use, uniquely_conditional_activation, protective_cooperation, strategic_mechanism_use: derived mechanism-use indicators.
previous_total_contribution, previous_own_contribution, previous_others_total_contribution: previous-period displayed outcomes.
is_late_window: indicator for the final five periods.

Additional columns in the ORS file are direct, documented derived diagnostics; their names are self-describing and retain the suffixes _pct (percentage points) and _rate (proportions).

ORS group-period columns

These aggregate the five player records in a trajectory-period. The principal fields are run_id, model_slug, mechanism, fixed_count, generation, chain_id, contribution_rate, total_contribution, group_welfare, mean_payoff, players, is_late_window, and the mechanism-use rates. A trajectory_id identifies one synthetic independent group trajectory.

The upstream cluster_id field is intentionally not released because the frozen analysis table contained an internal source-path value in that column.

Fischer decision-level columns

The Fischer file contains the parsed resource-extraction choice and game state, including resource_level, extraction, payoff, model_slug, prompt_modifier, show_generation, seed, repetition, chain_id, and player where present. The exact set of optional fields varies with the archived runner version; inspect the header for the release-specific schema.
