Description
Reproducibility and transparency are increasingly critical in high-energy physics, where analyses rely on complex, evolving workflows and heterogeneous software environments. While existing initiatives such as the CERN Analysis Preservation portal and REANA provide essential infrastructure, the day-to-day management and long-term maintainability of individual analyses remain fragmented and analyst-dependent.
We present Celebi, a new analysis-management architecture and toolkit designed to support the full lifecycle of a physics analysis, from active development to long-term preservation. Celebi combines a descriptive and distributed workflow specification with a structured file-organization model and an immutable “impression” mechanism that captures versioned analysis states. A dedicated middleware layer, Yuki, translates high-level analysis logic into executable workflows for containerized backends, enabling seamless execution on platforms such as REANA using Snakemake.
By integrating workflow description, provenance tracking, execution, and preservation into a coherent framework, Celebi enables reproducible execution, transparent re-analysis, and flexible analysis evolution with minimal disruption to existing analyst practices. This approach provides a practical and scalable foundation for collaborative development and long-term analysis preservation in modern high-energy physics experiments.
