Reorders don't stamp; container changes do — the moves-don't-stamp rule refined

User-ruled 2026-07-30: only within-container order-only rewrites (a reorder
among a lane's siblings, a lane reorder on the board, the renumber rescale)
skip the modified stamp and the modified-by clear. A move that changes the
item's container — cross-lane, cross-board, into or out of .trash/ — stamps
and clears both: which lane a card lives in is state, where it stands in
line is presentation. The trash move stops being an exception and becomes
the container rule's plainest instance. 01 scope/modified-by/Ordering/
Deletion/comments, 03 Trash, and 08's v7 bullet updated.

 **Resettled 2026-07-28 — the materialized trash.** The tombstone model (a `deleted:` flag on items left in place, rendered by a pure-view quasi-lane) is **retired**: it generated a standing tax of nesting rules — ancestor walks, effective liveness, entry-vs-universe splits, kind-homogeneous selection — that this design replaces wholesale. Deletion is now a **move**: deleting a card moves its folder into **`<board-root>/.trash/`**, a reserved, materialized container (01-storage-format.md). A trashed card is an ordinary card in a special place — search, selection, rendering, styling, and clipboard all treat it exactly like any other card, and `.trash/` is self-describing in Finder and to agents.
 
 - **Lanes trash too** (re-ruled 2026-07-29, retiring "cards only" and with it the design's sole destructive delete): deleting a lane moves its folder — subtree intact — into `.trash/`, exactly as a card moves; `kind: lane` in its frontmatter is what tells a trashed lane from a card in the flat container (01-storage-format.md ▸ Deletion), stamped on the way in when absent. The no-dialog posture survives for a better reason: the move is recoverable, so nothing needs confirming. Native undo's inverse is the ordinary move back (13-native-undo.md — the capture/recreate machinery retires). **A trashed lane is an opaque unit**: one distinct dimmed row showing its title and held-card count ("Doing — 5 cards"), no styling accents, never expandable; its cards are invisible to search and not individually addressable — it restores whole or purges whole. The row matches the search filter by lane title only. Lane rows and cards interleave in the one trash column purely by trash rank.
-- **Entry is always at the top** (settled): every arrival, card or lane — ⌫/⌘⌫ delete and drag-to-trash alike — lands at the trash's topmost position, minting an `order` rank above the current top. Newest-first ordering falls out of ordinary ranks by construction: **there is no `deleted:` key and no timestamp sort** — the trash sorts by `order` like any lane. The move **stamps `modified`** (the one exception to moves-don't-stamp, now stated in 01's `modified` scope — deletion is an edit to the card's story), which is what a future age-based auto-purge will read (deferred, 01-storage-format.md).

 - **Rendering**: trailing (rightmost) position when shown, visually distinct — dimmed/hatched header, trash SF Symbol, count badge; no new-card button; not draggable, not resizable, excluded from lane reordering. Fixed one width unit, consumed only while shown; Show/Hide Trash is a re-divide trigger (Layout above). **Visibility**: hidden by default; View ▸ Show Trash toggles (no default chord — ⇧⌘T belongs to the system's Show Tab Bar, 11-command-nexus.md); per-open transient state, resets to hidden, never persisted. Hidden, the trash is invisible to every gesture and to search; shown, its cards participate in the filter **exactly like any other card** — the point of the pivot.
 - **No Put Back** (settled): the valuable item is the card (or lane); where it goes on the way out is the user's cheap decision. Restoring is an ordinary move out: **drag** a trash card into any lane at any position — or a trashed lane row to a lane-strip slot — or **⌘X in the trash, ⌘V** — into a lane for cards, after the anchor lane for a trashed lane (04-interactions.md's lane-paste rule verbatim); the clipboard works on trash items like on any item, which is also the keyboard-native restore path (10-accessibility.md). Dropped on another board it follows the drag locality model (04-interactions.md).
 - **No editing in the trash**: trash cards don't open — double-click stops at selection; move it out first — and a trashed lane row never expands. Moving a card to the trash dismisses its open card window (05-card-window.md), and an external move-in observed by reload does the same; a lane entering the trash dismisses the open card windows of every card it carries (they entered the trash with it).
