# CK Rock AI > Chandler Klose's independent data and AI engineering work: data platforms, agent workflows, and reproducible reporting. ## Read - [CK Rock AI](https://www.ckrockai.com/): background, approach, selected projects, and contact routes. - [tokenledger overview](https://www.ckrockai.com/projects/tokenledger/): the activity-stream reporting method, the late-invoice demonstration, and current release boundaries. - [Chandler Klose on GitHub](https://github.com/cklose2000): public repositories. Consult each repository's own setup, status, and license. ## Status As of September 8, 2026, tokenledger's implementation is private and its public reference release is in preparation. This website provides a conceptual overview, not a live database, downloadable reference release, or comparative agent benchmark. tokenledger here refers specifically to Chandler Klose's activity-stream reporting project. It is not a claim of affiliation with another similarly named project. The demonstrated method uses synthetic data. Comparative agent accuracy and token efficiency remain unmeasured. Reproducibility alone does not establish source completeness or SOX operating effectiveness.
