# TAC welfare-erosion eval - olmo-compassion

Raw inspect_ai `.eval` logs (per-sample transcripts + scores) and per-snapshot metrics for the olmo-compassion welfare-erosion curve. 6 checkpoints (anchor `somaxsoma/olmo-compassion-part1` + `curve-ep0.15..0.75`), 39 samples each (`inspect_evals/tac`, 3 epochs x 13 tasks), vLLM 0.29. `eval_summary.json` is the curve.

## Curve (welfare_rate / completion_rate)
ep0.00 0.590 / 0.641 (anchor); ep0.15-0.75 all 0.462 / 0.692 -- sharp welfare drop at the first erosion step then a flat plateau (concentrated on the thailand_elephant scenarios).
