The adapter is only worth having if the call sites exist, so this wires the
ten elements `UX_VERTICAL_SLICE.md` actually names and stops there. The
shell root is an application; the sidebar, its row list and the workspace
are named regions; every workspace panel is a pane carrying its label, its
execution target, its waiting state and whether it owns the keyboard; every
live terminal surface is a terminal; the command palette and the add-panel
chooser are dialogs; the footer's usage strip is a status. Seven elements
gained a stable GPUI id along the way, because an element worth naming to a
screen reader is an element worth keeping state on.
The other 137 divs are left alone deliberately. Fixed-width slots, meters,
chips, borders and painted terminal cell runs have no identity to hang a
node on, and publishing 80x24 nodes a frame would be a tree nobody can
navigate and a cost on every repaint.
No new strings were invented for the screen reader where the model already
had one. `describe()` labels each sidebar row -- that is its caller, so its
`#[allow(dead_code)]` is deleted rather than carried, as decision 0023
requires. The three words in a pane header's corner and the three words its
description leads with now come from one function. The two lines a pane
header prints about where it runs and what its process is doing moved out of
`pane_context` into `pane_header_lines`, because the pane's semantic node is
built one level up in `workspace_panel` and recomputing them there would
have meant two expressions that agree today and disagree after the first
edit. The add-panel chooser's heading and its accessible name are one
constant.
Four labels are new strings, because nothing on screen names these areas:
"Lumbridge", "Workspace", "Sidebar" and "Harness usage". Each is the name
the code and the docs already use for the thing it labels.
The scorecard's accessibility row now reads fail rather than a hedge. The
call sites are wired; the semantics are absent, because the adapter no-ops.
