What this release contains
- Prospective three-condition study: no Wiki, flat history, persistent Wiki.
- Three independent replicates per condition across three evolution iterations.
- Frozen failure, protection, and transfer cases.
- 87 complete model calls and a 36-entry verifiable Skill Impact Ledger.
- Reproducible manuscript, source data, verification scripts, and machine-readable summaries.
Main result
The persistent Wiki reduced input tokens, output tokens, wall time, and final rule length relative to flat history, but did not improve mean task quality in this narrow study. The evidence therefore supports an efficiency and traceability claim, not a general quality claim.
Validation
- Artifact verifier passed for 9 result rows, 87 model calls, 36 ledger entries, and the PDF.
- BeforeDone paper and artifact checks were both fresh and PASS for the released files.
