From 5002c612298fe645791218059a69d2bc80a42d2d Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Tue, 29 Sep 2026 05:20:13 -0300 Subject: Newcol at the column cap says so, and a desktop session holds 16 columns Newcol with every column slot taken, or a column too narrow to split, did nothing and said nothing. It now fails (a ctl write with it) with no space for a column: 16 max (ENOSPC through 9ns), or that the column is too narrow. MAX_COLS is 16 on a desktop, 6 on the board; each column costs about 8 KB of core state (the Pardes struct grows from 1.47 MB to 1.56 MB), most of it its tag's text. fs.md and the skill give the cap.
