# Governed Skill Evolution from Persistent Agent Experience
Prospective ablation and cross-model transfer study of three experience-retention conditions for governed Agent Skill evolution: no persistent history, flat chronological history, and a persistent Pattern Registry with a forward-chained Skill Impact Ledger.

## Viewer subsets
- `replicate_results`: 9 rows, one per condition and replicate.
- `aggregate_results`: 3 condition-level descriptive summaries.
- `skill_impact_ledger`: 36 compact ledger entries. The full verified ledger, including digest material, remains under `results/`.
## Main result
Persistent Wiki did not outperform flat history on task quality in this setting. It used fewer input tokens and produced a larger target-model Skill gain, but had lower final task quality and more rollbacks. The release therefore preserves negative and mixed results rather than treating persistent state as automatically beneficial.
## Evidence boundary
This is prospective descriptive evidence for one synthetic deterministic grader, three replicate sequences, and two Codex model versions in one model family. It is not a causal provider comparison, safety certification, or broad claim about Agent performance.
