COLLAPSE ALL lived only on the column's own name — the label above the tree —
and that label scrolls with the list it heads: on a roll read deep the column is
scrolled past it, so the item looked like it only appeared once the top-level row
had been folded to bring the list back to the top. The row is where the pointer
already is, and it already carries the folder's menu.
The top-level folder row now leads its own menu with COLLAPSE ALL — rename,
rescan and remove follow it, and a subfolder row is unchanged, since folding a
whole tree is what a row that a tree hangs from can do and a row inside one
cannot. Both entry points run the same one: `root` on the menu state now means
"the head of a tree", the column's own name or the row of a folder picked at the
top level, and the menu draws the item first and then whatever the subject
itself has — the folder's items, or, on the empty part of the column, ADD
FOLDER. The empty part keeps ADD FOLDER alone: it is not the head of a tree.
Verified:
library-check.mjs — 35 steps, all passed. The new step right-clicks
lib-node-CheckRoll with the tree fully open (4 rows) and gets back exactly
[lib-menu-collapse, lib-rename-CheckRoll, lib-rescan-CheckRoll,
lib-drop-CheckRoll]; a right click on the column's name still answers with
lib-menu-collapse alone; the subfolder menu above is still the three folder
items with no fold in it; the empty column still offers lib-menu-add alone.
The fold itself is unchanged and still measured by opening the root back up:
4 rows → 1, and 3 back, with CheckRoll/2026/04 still away.
frontend tsc --noEmit clean. Live 8090 on index-DEvUJDNY.js matching dist/:

ponytail: the column's name is still the second way to the same item and still
scrolls with the list — left alone because the row is now the one that matters;
make the name sticky when a roll routinely fills the column past one screen.
