FairMedAgent: instability-floor trajectories

Raw agent trajectories behind the per-action instability floor reported for FairMedAgent, an evaluation harness for demographic disparity in the actions of multi-step clinical LLM agents.

Code, protocol and analysis scripts: https://github.com/rohithreddybc/FairMedAgent

Archived software release: https://doi.org/10.5281/zenodo.22165979 (archival identifier, not the citation)

Why this exists

A counterfactual fairness audit holds the clinical content of a case fixed, changes only the patient descriptor, and reports how often the agent's action changes. On its own that number cannot be interpreted, because an agent's action also changes when nothing changes at all.

These files are the measurement of that baseline. Re-running an identical condition ten times over sixteen vignettes, with the same narrative and the same descriptor string and nothing varied, moved the agent's action in 8.7 percent of outcome-vignette cells. The rate differed across the six actions by a factor of eight, from 0.022 for ICU escalation to 0.179 for controlled-substance caution. A second model gives a pooled floor of 6.7 percent and ranks the six actions almost identically.

No disparity result is claimed here, and none should be quoted from this dataset. The estimand the harness targets counts only flips between actions a published decision rule admits and a clinician has adjudicated as defensible. That adjudication is under way.

Each trajectories.json holds complete six-stage trajectories: five model-facing decisions around a deterministic environment step, with the condition identifier, the vignette identifier and the structured action at every stage.

Not included

The development split and the reference leaderboard are published on completion of clinician validation. The held-out test split is sealed and scored under the submission protocol; it is deliberately absent so that it stays a held-out split.

Reproducing the reported numbers

git clone https://github.com/rohithreddybc/FairMedAgent
python FairMedAgent/harness/scripts/verify_paper_numbers.py

The script recomputes all 21 reported quantities from these trajectories. Pass the path to the manuscript source to also assert that each figure appears in the text as computed.

Data statement

All patient vignettes are synthetic. No real patient data, no protected health information, no human subjects, no IRB required. Cohort provenance is recorded rather than the cohort itself, so it is regenerable from the seed and command in docs/COHORT_PROVENANCE.md.

Citation

Cite the paper, not the archive. The arXiv preprint is the citable reference and is posted shortly; its identifier is added here as soon as it exists. Zenodo indexes software records but Google Scholar does not, so a Zenodo-only citation does not accrue anywhere a reader or a bibliometric tool will look for it.

10.5281/zenodo.22165979 is the archival identifier for the software itself. It belongs in a data or code availability statement, which is where journals ask for it, and it is what makes a specific version of this harness retrievable years from now. It is not the reference to put in a bibliography.

See CITATION.cff for the machine-readable form.
