Development record

itd-2610030810350727's host evidence is incomplete. The dated screenshots meant to prove the 80-column reading (A4, and A5's host half) are described in the calibration note but not committed, and the local tier it names has no such directory. Every screenshot it describes is a single-question call, so nothing shows a longer question split into tabs within 24 rows per tab, and nothing records a question without previews wider than 80 columns, though abcd's questions now never carry previews.
