Pivot the trash to a materialized .trash — cards only, no Put Back

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.

 ### 7. Custom fly-to-slot drop animation
 
 Drags run as system `NSItemProvider` sessions (cross-board transfer, the copy badge), so a successful drop's replica gets AppKit's brief fade — not the fly-to-slot settle DESIGN/03 originally imagined; 03 resettled the drop as the board's (the held overlay renders the arrangement instantly at release). Reclaiming the literal fly-to-slot needs an `NSDraggingSession` bridge: mask the system fade, fly a shadow-window replica to the slot frame, hide the landed item during flight — a compositing dance that must stay correct across masonry reflows and multi-item drags. Fund only if the system fade ever reads as cheap in practice.

+### 8. Archive lane (`.archive` — the second materialized reserved lane)
+
+The materialized `.trash/` (DESIGN/03 ▸ Trash, the 2026-07-28 pivot) establishes the pattern: a reserved dot-named container at board root holding ordinary card folders, special only in how cards enter it. An archive lane — `<root>/.archive`, receiving cards that meet a criterion to be designed (age? a Done-lane dwell time? an explicit Archive command?) — is the anticipated second instance. Design open: intake criteria, visibility (a Show Archive toggle like the trash's?), search participation, whether archived cards count anywhere. Nothing committed; the trash proves the mechanism first.
