Assemble a sequential imaging dependency graph

Stages must be in dependency order. Forward references and cycles fail. File inputs must use reflow_imaging_input() so content changes invalidate a resume. Plain character arguments are configuration, not tracked file inputs.

Usage

reflow_imaging_plan(..., packages = character())

Arguments

...

Stage specifications.

packages

Additional installed packages to fingerprint, for example optional backends used by a stage. Declare these explicitly.

Value

A versioned plan; no stage is executed.
