Off Track Outputs

Gallery / Feature Showcase

Off-track file artefacts hung above a pre-processing trunk at the step that writes each one: `%%metro off_track:` on a producer-fed sink anchors it to its producer (not the section top), mirroring the off-track input mechanism for outputs. Each output gets its own column clear of the next station, and a step writing several files (MarkDup here) stacks them above it.
