T59: the newest line typed is the one of the highest number, not the lowest on the screen, so a prompt drawn at the top over older lines takes its clicks; a press goes no lower than that line's last row or the cursor's

 | OSC 8 and plain links on Cmd-press, Ctrl-press off macOS; inside herdr, herdr opens them whole | T09, T45 | `term::links` tests; on macOS with real herdr 0.9.5 and a stand-in `open` on its PATH, Cmd-press on a URL herdr wraps, on its wrapped tail, on an OSC 8 link and on a URL over three rows opened the whole URL and the OSC 8 target, where before the app opened `.../ELYTermin` and nothing; Cmd-hover underlined the long URL across its rows; outside herdr the app opened the URL itself; an OSC 8 link whose label holds `file:///etc/hosts` and whose target is a web page opened the page through herdr, which keeps the target from the terminal while it takes the mouse; Shift-Cmd-press on a plain `file:///etc/hosts` inside herdr the app opened itself, caught by an `NSWorkspace` stand-in | Pass |
 | Focus reporting, title, scrollback limit, find | T10 | `term::find` tests; round 3 failed at the cap, its fix stands on a red-green test | Pass |
 | A scrollbar over the history: a drag on its thumb scrolls, whatever the program does with the wheel | T58 | `term::scrollbar` test: the thumb's share and place follow the history and the view's offset, and a place past either end of the track holds at it; under Xorg's dummy screen, after `seq 1 500`, the thumb stood at the bottom right, a drag to the top showed the first prompt and lines 1 to 39, and one back down lines 220 to 259; with mouse tracking on, the wheel went to the program as reports and did not scroll, while a drag on the thumb showed lines 245 to 284 | Pass |
