+# Improvement Evaluation Artifacts
+
+This folder contains deterministic baseline-vs-trained-style evaluation outputs for all 15 CommitmentOS tasks.
+
+## Files
+
+- `eval_protocol.json`: fixed protocol (task set, seed, max steps, decode config)
+- `baseline_eval.json`: per-task baseline rollouts
+- `trained_eval.json`: per-task improved/trained-style rollouts (same protocol)
+- `improved_eval.json`: alias of trained outputs for backward compatibility
+- `comparison.csv`: task-by-task delta table
+- `summary.json`: aggregate metrics (mean/median deltas, difficulty splits, steps, success)
+- `case_study_hard_011.md`: concise before/after narrative for one hard scenario
+- `reward_by_task.svg`: visual comparison of final reward by task
+- `violations_before_after.svg`: visual comparison of commitment violations
+
+## Reproduce

+- Resolves lower-priority personal conflict (`cancel_event evt_90`)
+- Preserves high-priority investor objective (`book_restaurant Sky Lounge`)
+- Renegotiates existing social commitment via communication (`send_email Team`)
+- Confirms delivery to executive stakeholder (`send_email VP_Chen`)
