Greenbar prints your operations as a continuous-form report: a numbered listing, a fixed-width result code in the gutter, a struck stamp at the footing. It is the printout the terminal was always trying to be.
Three mechanics carry the whole language. None of them is decoration — each is how the report is meant to be read.
State is a fixed-width code in the left gutter — 000 clean, W12 held, E04 reject. Scan one column, not a field of badges.
The alternating green stripe is the row rhythm itself, carried straight off continuous-form paper — separation without a single boxed cell.
A run is footed and struck with an angled rubber stamp: posted, reconciled, held. State as a mark, never a soft pill.
This is the actual output — the same listing block the product ships, rendered on the form.
