Text wraps at width
Tests whether text that exceeds the terminal width automatically wraps to the next line. This is controlled by DECAWM (auto-wrap mode), which is enabled by default on virtually all terminals.
How this is testedautomated
Write 85 characters, verify text wrapped and a character appears on row 1.

The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
