Phase 2 swaps every consumer: Liveness and its ancestor walk are gone,
replaced by ItemContainer — a UUID set plus the container side it
lives on, presence the whole test, one selection boundary instead of
the old liveness law. Deletion stages by place: board cards move to
the trash at a store-minted head rank, trash-side delete is permanent
behind its confirmation, Delete Immediately skips the trash from
anywhere, lane delete captures the subtree and removes the folder.
Restore has no method at all — moveCards resolves members in either
container, so drag-out and cut-paste are the ordinary moves 13 calls
them, registering ordinary Move steps. The delete inverse moves the
card back to its captured lane and rank; redo replays the captured
trash rank, a value the gesture actually wrote; lane undo recreates
the subtree byte-faithfully in session. Purges register nothing —
where 13's trash section contradicts its own Rules on that, Rules
wins, filed for ruling. Staleness collapsed to present-or-absent: a
container is a path, so a foreign restore fails the delete step's
expectation structurally. Legacy tombstones migrate on the loose-file
tail hook, cards oldest-first so minting above top reproduces the
retired newest-first column, lanes returning live, one folded loss
row naming both directions. Put Back, restoreByDrag,
receiveRestoredCards, TrashEntry, and the kind machinery are deleted;
the trash column renders the container correctly with its full face
rework left to phase 3.

Phase 1 of the trash pivot: the file format learns .trash/. The loader
parses the reserved root container — cards only, one shared parseCard
for both containers so fail-fast, attachments, and verbatim documents
are literally the same code; absent means empty; symlinks and
lane-shaped nestings fall out as strays by construction. BoardModel
grows snapshot.trash as a plain rank-ordered card list — the container
has no identity to carry. Legacy deleted: keys keep flowing through
the retiring flag path so every tombstone consumer stays green, and
are additionally reported through LoadResult.legacyTombstones in the
loose-file idiom for phase 2's migration scheduling — nothing vanishes
from view before its folder has actually moved, which is also 01's
lock-deferral posture. Writer primitives land value-passing: move to
trash with caller-minted rank and the deliberate modified stamp,
tombstone migrations that surgically remove the key, physical lane
removal, per-card and whole-container purge that leaves strays
verbatim, and byte-faithful whole-subtree capture/recreate for lane
undo. Board-wide identity now spans the trash, so an import colliding
with a trashed UUID remints instead of colliding. The watcher already
delivered .trash events — isGitInternal tests a component, not a dot —
now stated and pinned rather than relied on.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
The command surface was already almost entirely platform machinery —
this card proves it and pins it. Headless probes established that
NSWindow.validateMenuItem answers enablement AND rewrites the row title
from the delegate-supplied manager, so 'Undo Move 3 Cards' flows step
phrase to Edit menu with no code of ours; under the lock the rows dim
and keep their names, the correct reading of the-stack-survives. The
toolbar twins validate through validateUserInterfaceItem, which never
touches labels — 03's static-label exception proven rather than
asserted — and their specs' enablement abstention is pinned so nobody
later adds a second, disagreeing answer. The one link a headless run
cannot close is the nil-target key-window resolution itself: standard
responder-chain behavior with none of our code in it, left as the
manual check. Base-edition 'disabled without undo' scaffolding is
reworded away — every base board has undo now. New suites cover the
trash's two doors (delete-then-undo byte-identical to Put Back's
effect), position-preserving restore of a middle card, and the
capstone: five gestures forward, five presses back to the origin
board, five forward again, the menu phrase asserted after every press.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
Every crossing validates its expectations before writing: each step
carries per-item HistoryExpectations — folder, effective ancestor-walked
liveness, and exactly the fields the gesture set — and a mismatch pops
the step, posts the signpost ('Undo skipped — Fix login changed outside
Lanework'), and falls through to the next. Validation reads disk, not
the in-memory snapshot: the snapshot is by construction one reload
behind every app write, so a rapid second undo would false-skip against
the pre-state — disk is what current can honestly mean at press time.
Stale and failed part ways: a stale step is one the board moved past,
so dropping it loses nothing; a failed one is refused by a usually
momentary condition, so it stays put and the crossing stops with only
performWrite's own error row — which forced the provider off
NSUndoManager onto two plain arrays, since a popped group cannot be put
back. The read-only lock disables Undo/Redo through the adapter while
the stack survives to resume on clear. Delete and restore validate
presence alone — a machine timestamp is not a decision — and a
malformed field matches nothing, since it is a shape the app never
writes.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
The store is the Writer boundary, so it computes and registers
inverses: a weak history sink bound at session composition, one
HistoryStep per gesture at exactly the brackets that were already one
performWrite each — multi-card moves, style batches, width pairs, and
multi-row restores each undo as one plurally-titled step, and the Edit
session registers once at the flip from the bytes disk held before its
first landed write, debounce ticks registering nothing. Crossings run
through performWrite, so an undo brackets the watcher, echoes through
the reload, and reaches every window; every closure captures values,
never snapshots. The inventory follows 13 exactly: moves return to
origin lane and order, renames restore or remove the title key,
restyles and resizes restore field values or absence, tombstones and
restores swap with captured timestamps, and an undone create is a real
removal — no trace — with redo re-materializing the same UUID from
bytes captured at gesture time. Purge, attachments, repair,
bookkeeping, checkbox flips, raw Apply, and the whole arrival family
register nothing, each exclusion documented where it lives. Step names
speak 06's verb vocabulary through the new HistoryPhrase.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
The provider seam 12 promised: HistoryProviding speaks 13's vocabulary
— register a HistoryStep (bare 06 phrase plus undo/redo closures
returning applied or skipped), canUndo/canRedo, action names, clear —
and no UndoManager type appears anywhere in it, proven by a fake that
satisfies the seam with counters. The base provider wraps a private
UndoManager with groupsByEvent off so coalescing stays the Writer call
site's decision; undo re-registers the reversed step from inside the
undo, which makes a stale-skipped step vanish for free and the
crossing loop fall through to the next. BoardUndoManager adapts the
protocol to the responder chain — a stackless UndoManager subclass
answering from the provider — so Pro's git provider inherits menu
enablement, dynamic titles, and the nil-target toolbar pair by binding
the protocol. One stack per board session, born in beginSession,
cleared in the close flush; every window over the board answers it
through windowWillReturnUndoManager. Headless probes shaped the
routing: a real NSTextView's own manager wins natively, but a field
editor's does not — BoardUndoRouting answers the per-window text
manager while any NSText is first responder, so a search-field typo
never crosses a board step.

The editing surface: the same hosted TextKit-1 text view gains an
editable branch with a per-keystroke line-scanner highlighter — chosen
over a parser re-parse because a mid-typing buffer is usually invalid
Markdown and 05 wants the delimiters themselves dimmed; apply only sets
attributes, so presentation-never-transforms is structural. Saves ride
a ~700ms injectable debounce through BoardWriter.writeBody —
toggleTaskMarker's idiom widened to the body span, frontmatter bytes
untouched, refusing to write when disk already holds that body, which
enforces all three gates (untouched, reverted, echo) at the layer that
owns the bytes with one isDirty predicate above it. Mode grammar lands
whole: ⌘E toggles with a checkmark, Return in Preview enters, Escape
returns, and every flip flushes first; window close flushes through
the existing retry/save-copy/discard modal, and the dismissal flush
deliberately reaches a tombstoned card. Dirty-buffer-wins: disk always
follows the snapshot, the buffer only when clean, both surfaces render
the buffer. Undo is the editor's own session-scoped NSUndoManager;
endEditSession names the pro-m1 one-commit-per-session boundary.

application(_:open:) forwards every Finder-delivered URL to
AppModel.openBoard(at:) — the exact path welcome and File > Open use, so
a Finder open gets the same registry record-before-load, recents stamp,
already-open-focuses-its-window dedup, and row-level failure surfacing
on welcome (DESIGN/02 > Launch). A cold Finder launch can arrive before
any scene has captured the window opener; openBoard now buffers such
URLs and captureWindowActions replays them once opening is possible.

Nexus parity, audited row by row (11-command-nexus.md § Menu commands) —
every already-built item's title, chord, and placement matched exactly;
this pass fills what remained:
- The future-window rows, present with stable titles and validation-driven
disablement until their milestones fill the actions: Save as Template
(m9), Add Attachment… ⇧⌘A, Find Next/Previous ⌘G/⇧⌘G, the View-menu
card triplet Edit Body ⌘E / Raw Source ⌥⌘E / History (m6), Board ▸
Pull/Push (git milestones) — one shared disabled-row shape in
FutureCommands.swift so later milestones only flip validation.
- No Print story in v1: the print group is removed.
- Help carries the Nexus's one remap-teaching line — Customize Keyboard
Shortcuts…, opening System Settings' Keyboard ▸ Shortcuts extension
directly (the modern extension URL, verified to launch the appex).
- The launch-restore decision now runs through a pure, tested
AppModel.shouldRestoreAtLaunch gate; the Settings pane's caption rides a
proper Form section footer.

⌘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.

BoardRecord carries icon/iconColor; recordOpen/recordClose stamp them with the
display name, and a displayStateDelegate on the store (wired in BoardWindowHost
beside onFrameChanged) syncs all three through BoardRegistry.syncDisplayState on
every successful reload — welcome rows now wear the board's own icon and follow
in-app renames live. recordOpen now runs before the load with the folder name as
a brand-new record's provisional display name, so a first open that fails
fail-fast still lands in recents carrying the failure row-level (02's rule); an
existing record's cached name survives a failing retry, and the welcome fallback
list remains only for failures naming no record at all.
Claude-Session: https://claude.ai/code/session_01CqjXB7ASoWtbyoGod68k97
The welcome window becomes the real thing: Xcode-style, hidden title
bar with background drag, branding and actions left, recents right —
rows carrying the board symbol, name, location, and the registry's
cached lane/card counts (stamped at close, never a scan at welcome
time), sorted by last opened. Launch failures surface row-level per
02: a failure joins its recents row as a warning caption, an
unresolvable bookmark renders unavailable with Forget its one
affordance, and only a failure with no row to carry it falls back to
a compact list; a board opening again heals its row. New Board
(Opt-Cmd-N) opens the Pages-style template chooser — shipped with
the single Basic template and the m9 seams marked — flowing through
the save panel into createBoard/createLane and straight into a board
window. Open Recent gains its submenu with Clear Menu (byte-identical
to forgetting every row, pinned by test), and File > Duplicate forks
the frontmost board to a Finder-style copy sibling: pending work
flushes first through the close flush's step two alone (sessions stay
open — 09's stated exception), every GUID and tombstone carries (the
whole-board carve-out from copies-remint), and the copy opens in its
own window while the original stays put. 36 new tests.

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.

Four scenes (welcome, restore bootstrap, board group, card group) with
system restoration disabled in favor of the registry's open-now flags:
set when a window actually opens, cleared only on user close, so quit —
and crash — leave exactly the restoration set behind. AppModel joins
windows to sessions (shared store, registry record, card refs, held
security scope); CloseFlushCoordinator pins 02's strict close order as
a seam-injected machine (card sessions end, windows drain, store
flushes, record stamps, teardown) with named slots where m6/m7 flushes
land. HostedWindowController proxies — never replaces — SwiftUI's
window delegate to intercept windowShouldClose for the flush, report
frames, and place saved frames onto live screens. Card windows are
(board path, case-folded card id) values: reopen focuses, and a
snapshot-pure fate function dismisses on delete, tombstone, tombstoned
lane, or cross-board move.
