AI / Apache Burr Interview questions

What are Projects, Applications, and Steps in Burr’s tracking model?

Burr’s telemetry data model has three nested levels:

LevelMeaning
ProjectThe top-level grouping, set as the required argument to with_tracker(project=...). Shown as the first page in the UI.
ApplicationA single run logged under a project, similar to a "trace" in distributed tracing. Optionally named with the app_id argument.
StepAn individual action execution within an application, showing state, input, and result at that moment.

This hierarchy is what powers the Burr UI’s navigation: pick a project, drill into an application, then step through its history.

In Burr’s tracking model, an "Application" most closely maps to which concept in distributed tracing?
Which tracking level is required as an argument to with_tracker()?
