API Reference

Orientation hub for the bfabric-app-runner API. An app is described by three YAML specs plus a Python execution API:

• App spec (app.yml) — the app’s versions and its dispatch/process/collect commands.

• Input spec (inputs.yml) — the files an app needs and where to fetch them.

• Output spec (outputs.yml) — the artifacts an app produces and how to register them.

• Python runner API — Runner / run_app, for driving the lifecycle programmatically.

Each spec page below is the canonical, field-by-field reference for its models. For how the pieces fit together in the dispatch → process → collect lifecycle, see the Architecture Overview.

• Python Runner API
