From 12d387e4a03204a2b6d0c51633e228063e883fad Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 09:50:21 -0300 Subject: A root commands file lists every builtin, its argument and which ctl takes it A script could learn the builtin words only from source or the Help window. /commands is generated from the registry: one line per builtin, Word or Word arg, then root or pane for the ctl that takes it, so it is always this build's own list.
