Designed with the user 2026-07-29 (Redesign card 82e2de6c, storage half; UI half remains open). A comment is a UUID folder under comments/ holding index.md + optional attachments/ — a card's anatomy one level down, every fractal rule applying verbatim. Field table: kind: comment, lenient self-reported author (content, not overlay — survives app writes), created/modified; no title, no order. Threads sort chronologically by created (ranks rejected: independent clocks across machines and trackers), flat this iteration with nesting deferred. Comment defects never refuse the board — stray posture at worst. Delete skips the trash, undoable without confirm. Copies carry the thread, reminted, stripping remote/remote-state so two local comments never claim one remote object. Comments are window-scoped, outside the board snapshot — the walk stays O(cards); the committer already protects them via whole-root staging, and composer/announcer describe foreign comment changes by path shape. Count chip on faces filed as WISHLIST #9. Schema edition-blind.

The tombstone model is retired wholesale: deletion is a move into the reserved
<root>/.trash/, always entering at the top (rank minting — no deleted: key, no
timestamp sort), with modified stamped for the future age-based purge. Lanes
are never trashed — lane delete is physical, native undo in-session the net.
Put Back is gone: restore is drag-out or cut+paste (⌘X now enabled in the
trash as the keyboard restore path). Trash cards are ordinary cards — search,
selection, clipboard, and rendering uniform — and one container boundary
replaces the effective-liveness, ancestor-walk, and kind-homogeneity machinery
across 02 and 04. Delete stages by place (board moves, trash deletes
permanently under the recoverability confirm); legacy deleted: keys migrate
without destroying (cards relocate, lanes return live, notices). Templates
exclude .trash; Duplicate carries it; the agent guide teaches delete-as-move.
Materialized reserved lanes are named as a pattern — .archive is WISHLIST #8,
and the backed-out release-presentation question is marked open in 03.
Ruling: Redesign board Resolved card e8f1a6c2; 19 mooted tombstone-era rulings
moved to the board's new Mooted lane.

Rulings written in place: the drop settle yields to the system drag session
(fly-to-slot deferred to WISHLIST #7) and the held proposal's home is the
app-wide DragSession — rendering the arrangement means rendering the card at
release (03, 02); folder drops refuse at hover with loss-row reporting, created
cards land positionally, N shadows, header resolves topmost, shadow-only
feedback (04); the banner vocabulary gains the warning-tone loss row class
(02); all user-initiated creation clears the search (04); loose files beside a
card's index.md relocate into attachments/ with notice — files-only carve-out,
paste normalizes at the boundary, the agent guide teaches it (01, 04, 08);
dropping a card on the shown trash deletes it, shadow pinned topmost (04);
query-emptied lanes keep their slot, the out-transition stays reachable, an
open rename survives the filter, pasteboard staleness accepted (04).
The face carousel does not carry over: the pathfinder's selection-keyed dual
presentation proved undesirable — one presentation per card, selection changes
styling never geometry; the attachment chip and the card window are the whole
media story (03, 01, 10, 11; the same-day carousel settlements superseded on
their Resolved cards).

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.
