When something looks wrong

A check found nothing on a screen I expected it to

The screen checks need the screen read first. Screens that came in as pictures are read on import; for Figma frames, check the screen's kind is right, because the kind decides what it owes.

Wire up skipped a control

It only wires what it can name a destination for. Mark the control, or wire it by hand with L.

A comment moved to the rail

Its screen or control was removed in a re-import. The comment is kept and listed rather than deleted; reply or resolve it there.

I deleted something by mistake

⌘Z straight away, or Version history in the flow menu after a reload.
