⌘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 second half: system drag sessions over phase 1's model, per
DRAG-REORDER.md and 04-interactions.md § Drag & drop.
- Card faces, lane headers, and trash rows drag as NSItemProvider sessions
(two exported UTTypes, JSON payload in flatten order, plain-text titles as
the secondary representation) — replacing m4's custom lane-reorder gesture
and trash drag-out wholesale; the app-wide DragSession carries the members,
the frozen dragged sizes, the live proposal, and the effective operation.
- Three drop delegates (lane masonry, strip, window fallback), each accepting
both types and routing internally per the single-target-dispatch rule; the
cursor is the physical mouse converted to strip space; proposals come from
DropSlotMath with hysteresis threaded through, and the lane-strip proposal
clamps in front of the shown trash.
- Locality picks the default — move within a board, copy across, the badge
tracking live; ⌥ forces copy (ignored on within-board lane drags), ⌘
forces move; trash rows restore within their board (positional), copy out
across boards by default, ⌘ forcing the true restore-move.
- N contiguous shadows with reflow keyed on the proposal; the
committed-overlay hold renders the dropped arrangement until the reload
echo lands (1.5 s dissolution deadline for refused writes); the
re-grounding trio: geometry re-derives per render, proposals re-validate
by liveness at release, an emptied drag cancels itself.
- Edge autoscroll (ticking driver over DragAutoScrollMath, re-targeting per
step), the mouse-up-gated late-event cleanup, and the polling watchdog —
the pathfinder's lifecycle traps, ported.
- Store: moveLanes and multi-card restoreByDrag join the one-bracket drop
commits.

createBoard fills or mints a .kanban (or extension-less) folder and
refuses to clobber an existing board; createLane/createCard mint fresh
lowercase-UUIDv4 folders and append at max+1024 among visible siblings
via the same strict scan renumber uses (extracted, shared). New files
carry schema/title?/order?/created/modified — created==modified, no
modified-by — written LF through the same atomic temp+rename path.
The editability pre-flight is now scoped to operations that rewrite
siblings: renumber refuses on an uneditable sibling, a create beside
one proceeds. Schema constant unified on BoardLoader.supportedSchema.
Info.plist declares the .kanban document type (UTI conforming to
com.apple.package) so Finder treats a board as one document.
