The board window's accessibility tree per DESIGN/10: lanes are containers
labeled "<title>, lane, N cards" (filter-aware count = renderedCards, the
badge's own collection); cards are one flattened element each — label =
title or the untitled placeholder, value = attachment count + "cut,
pending paste", selection via trait; face icon, stripe, and paperclip are
decorative and hidden. Masonry never leaks into traversal: slots carry
order-keyed accessibilitySortPriority, so a wide lane reads by card order,
not column-major. Lane titles carry the heading trait for the rotor.
VO-Space is the ⌘-click analogue routed through the existing
BoardStore.click funnel (SelectionGrammar stays the single answer for
toggle and container-boundary rules) — cards and lane headers both.
Context-menu rows double as custom accessibility actions, each calling
the same private method as its menu row so the surfaces cannot drift;
trash cards expose Delete and Reveal in Finder and never Open. The trash
column is pinned last via sort priority 0, its label/value re-routed
through the new AccessibilityPhrases seam; toggling trash visibility
posts a one-line announcement from the store seam (both command faces).
The invisible lane-resize drag strip leaves the tree — the stepper and
menu items are the accessible width path.
AccessibilityPhrases is the pure vocabulary seam (labels, values, plural
folding shared with TrashModel.phrase), pinned by its own test suite.
Both schemes build; 1466 unit tests green.

Phase 3 finishes the pivot at the surface. One card face serves two
containers: CardFaceView extracted with a role — board or trash — so
stripe, tint, chip, selection stroke, cut dim, marquee registration,
and drag are shared by construction, the trash side differing only in
its absences: no Open, no rename, no Style, no file-hover highlight,
and a Delete that goes through the confirmation host. The column
rewrote around the lanes' own single-column masonry so drag reflow
reads as positional slides; chrome stays the hatched header, symbol,
and count — 11 gives Empty Trash to the File menu alone. Two real
grammar bugs die here: plain Backspace on a trash selection purged
without the confirmation the menu raises, and the context menu's
Delete resolved against the standing selection, so right-clicking a
trash card under a board selection silently did nothing — it now
stages the clicked set explicitly. Open, Rename, Style, and Empty
Trash validation became testable store seams; the column is one named
accessibility container of ordinary card elements. The tombstone era
is swept: deleteItem, restoreItem, stripTombstonedChildren — dead
since lane copies stopped nesting trash — the restore verb, the
unreachable put-back banner row, and every quasi-lane doc comment.
