⌘X/⌘C/⌘V for cards and lanes per 04-interactions.md § Clipboard:
- ClipboardStore stages full folder snapshots eagerly at the gesture into
Application Support (at most the current copy; sweep at launch and on
each copy purges what the pasteboard no longer references; a copy made
before quitting pastes whole after restart) and writes the pasteboard a
JSON manifest — every entry embedding its index.md, lane entries their
cards' too — plus plain-text titles.
- Cut is Finder-style deferred: items dim in place off pendingCut, void on
pasteboard takeover (changeCount, no timers), source-board close, or
per-item external tombstoning; the first armed paste moves the surviving
originals whole (tombstoned interior cards land in the destination's
trash), a second paste materializes copies from staging.
- Paste anchors by the shared flatten-order rule (NewCardTarget's anchor,
extracted); a tombstoned selection never anchors; lane paste reaches the
right end and stays enabled on a zero-lane board; paste into the source
board is the within-board lane duplicate; copies keep created, take
fresh GUIDs, and strip tombstoned cards; trash-sourced copies strip
deleted: at materialization; ⌘X is disabled on the trash side.
- A degraded paste is loud, never silent: staging gone → the embedded
index.md fallback lands content-intact, attachments absent, and a
BannerCenter-phrased row names what was lost.
- The standard Edit items validate through conditionally-attached
onCommand handlers, so AppKit's enablement mirrors the availability
predicates; text fields keep their own clipboard while focused.

The board's fixed grammar keys and the menu-backed chords of
04-interactions.md § Keyboard, per the Command Nexus inventory:
- Spatial arrow navigation (NavigationMath.nearest over the marquee
registry's frames — one geometry source), walking across interior
masonry columns, lanes, and into the shown trash; ⇧-arrows extend via
the same range function as ⇧-click and go inert at the liveness and
kind boundaries; ⌥-jumps with the ⌥↑ lane-domain escalation and ↓
descent; the empty selection seeds at the first lane's first card;
selection scrolls into view.
- selectionHead — the navigation cursor beside the anchor, set by every
click, moved by every arrow, dropped by the reload vanish rule.
- Board ▸ Open Card ⌘↩ (the one command enabled mid-edit: commits the
placeholder or rename and opens), Move Up/Move Down ⌥⌘↑/⌥⌘↓
(within-lane sort, gather-then-step, rank-permuting writes in one
bracket), Move Left/Move Right ⌘←/⌘→ (sole lane, one slot, never the
trash) — all validating and acting off one shared answer.
- Delete now selects the Finder-style successor sibling from the
pre-write snapshot, so repeated ⌫ walks down a lane; external
vanishing still only shrinks the selection.
- handleReturn rejects modified Returns; the trash column renders
eagerly so every row stays registered for navigation and the marquee.

The full pointer grammar of 04-interactions.md § Selection, stated once
as a pure function (SelectionGrammar) and reached through one store
funnel from every click surface — card face, lane header, lane empty
space, trash row:
- Plain click replaces and anchors; the lane surfaces (header and empty
space alike, per the settled one-lane-click-behavior rule) toggle off
on a sole-membership repeat.
- ⌘-click toggles within a homogeneous set; crossing any axis — cards
XOR lanes, live XOR trashed, card entries XOR lane entries in the
trash — degrades to a replace, so no click can produce a mixed
selection.
- ⇧-click ranges from the anchor in the (side, kind) order list: flatten
order for cards, lane order for lanes, the trash's deterministic sort
filtered to kind — the pointer twin of the keyboard's boundary rule
(the keyboard goes inert, the pointer skips).
- The rubber band (MarqueeSession/MarqueeMath) arms from lane empty
space, the board backdrop, and the trash column; side frozen at the
origin, trash bands homogeneous by topmost kind, frames self-registered
in strip space, geometric begin guard, never animated.
- Fast plain double-click opens the card window (⌘↩'s pointer twin);
Select All answers the standard Edit menu item via the responder
chain, trash- and kind-respecting.
- The range anchor lives in TransientBoardState beside the selection and
obeys the same reload vanish rule.

One style-editor component, anchor-agnostic: a background grid (None
well plus the 12 palette colors) and a curated symbol grid (the
pathfinder's five-dozen set, leading well removing the icon key for
the level default), selection-aware across cards, lanes, and the
board itself. Batch edits compute per-dimension state — uniform,
mixed (no well selected), or an off-palette value labeled verbatim
outside the grids — and choosing a well applies to the whole target
set as one write bracket, skipping no-ops per field. The popover
tracks its target set live per the freshly ratified rule: targets
re-resolve by UUID on every reload, a vanished target leaves the set,
an emptied set dismisses the editor, and nothing ever silently
retargets to the board. Anchors landing now: Board > Style
(Opt-Cmd-S) and the card/lane context menus, which also carry the
quick-style recents row (app-wide, persisted, capped at six, None
never recorded) and the lane's width control twinning the menu
chords. The styling system's other two renders arrive with it: a
lane's background paints the C7 top-edge band, the board's paints
the window content background — malformed values paint nothing and
stay byte-identical on disk. 31 new tests.

The lane title bar becomes real: leading SF Symbol (hand-written names
render leniently, unknown ones fall back to the level default), title
or secondary untitled placeholder, a quiet count badge that counts
exactly the cards the body renders (so the m5 search filter is
followed by construction), and a new-card button. The whole bar is
the reorder drag surface — no grip — with click-vs-movement splitting
select from drag; a pure proposal function maps the drag to an
insertion index and release commits through the Writer's same-parent
degenerate reorder, compacting and retrying when midpoint precision
runs out. Clicking never edits: inline rename is Return on the sole
selected card or Board > Rename for either kind, a third transient
editor beside the placeholder that tracks its target by UUID, commits
on focus loss, discards silently when the target vanishes, and
removes the title key on an empty commit. The new-card placeholder
renders at last — the settled Cmd-N target rule (pure, tested) files
it after the anchor card, at a selected lane's bottom, or into the
last-active lane; Return commits and re-selects the lane, Cmd-Return
also opens the card window, and a failed create discards the overlay.
New Card / New Lane / Rename land in the menus with focused-editor
and read-only validation; rename gets its own WriteOperation case in
the banner vocabulary. 59 new tests.

TransientBoardState, one per store, holds state by how a reload treats
it: item-referencing sets (selection, drag membership, pending cut)
share one shape and one constraint rule — members must exist in the
current universe — applied in two directions by one primitive, so the
search filter's hidden-cards rule and reload survival are one rule
expressed once; derived state is stored as its inputs only (the query,
never its result set); and the new-card placeholder is a lane-anchored
overlay with no UUID until commit, discarded when its lane vanishes or
tombstones, handed off when the created card's UUID appears. Trash
visibility rides along per-open, never persisted. The decision is
written back into DESIGN/02 § Changes from Kanban — the TBD is closed.
Full suite 352 tests in 64 suites green. Two findings filed.
