The settle rule 3f4125e introduced — at release the shadow swaps for the
dropped card(s) drawn in place immediately — is withdrawn on review. The
board returns to the presentation the committed-overlay hold has always
had: the shadows keep standing at their landing slot and the originals
keep their lift until the echo reload lands, whatever the operation was,
and the real faces arrive with the snapshot that carries the write.
Gone with it: the DropLanding/DroppedItem seam and the three landing
accessors, the hold's landing/operation payload and the removesOriginals
and keepsIdentity halves it decided, the pickup-captured titles a
cross-board arrival's face needed, LaneSlot.dropped with DroppedFace and
DroppedCardFace, the strip's dropped-lane run, and the trash column's
settled tombstone rows — the same presentation at the delete gesture's
end, which goes for the same reason while the drop-to-delete write and
its shadow row stay exactly as they were.
Kept: the hold itself, which predates the commit, along with the 1500 ms
failed-write timeout, its injectable duration and its extracted expire,
and the guard that keeps a settled release past retargeting. The tests
pinning those stay; the ones asserting what the landing slot drew are
gone, and the suite now pins the hold's own claim — the arrangement does
not move at the release.
The pause between the release and the echo is therefore an open design
question again, filed on the Redesign board.

The m4 scene plumbing was already honest — one WindowGroup value per
CardWindowRef enforces one-window-per-card, and CardWindowFate's
ancestor walk answered dismissal — so this card fills the window: a
two-column shell whose body column takes all resize flex and whose
sidebar width derives once from font metrics (26 characters of average
body advance plus em gutters), the five 05-ordered section headers as
placeholders, and the card body as selectable plain text until Preview
mode lands. The fate walk now returns a CardPlacement (card + lane), so
one pass answers both liveness and the live board › lane subtitle; a
board rename lands for free through displayName. Card windows remember
their frames per card in the board record (case-folded id keys,
unchanged-writes-nothing), restoring instead of cascading; only
unremembered cards take the last-used size and cascade. Store
acquisition stays gated on liveStore — a card window never opens a
board — and the close-flush hook stands with nothing to flush until the
Edit-session card.

01's Lanework-owns-the-board carve-out: a regular file beside a card's
index.md belongs in attachments/, and the app moves it there. The
loader detects read-only — a new LoadResult.looseCardFiles channel,
separate from the stray-tolerance warnings because it says the opposite
thing — skipping directories, symlinks, hidden entries, and the
reserved names compared case-insensitively (on APFS, Index.md IS the
index). The relocation rides one performWrite bracket at the tail of
every successful reload, which makes lock deferral free: the reload
that lifts a read-only lock is the reload that relocates. A
lane/card/filename memo keeps a failing relocation from hot-looping —
one one-shot, then silence until disk changes. The notice rides the
loss-row class, phrasing folded by BannerCenter (one file, one card's
files, a multi-card sweep), naming original filenames per the
importAttachment rule. Paste normalizes at the import boundary: staged
snapshots' loose files land in the pasted card's attachments silently,
every arrival path declaring its side via an explicit
normalizingLooseFiles parameter — drag paths decline and fall back to
the destination's own carve-out. checkIsCardFolder closes the hole
where a lane's notes.txt would have been relocated: card depth is
exact, UUID under UUID.

Creation now clears the search by mechanism, not gesture: one seam
(noteUserCreation) states 04's rule once, called from the placeholder
funnel, paste — cards and lanes, after the staleness guard so a stale
paste clears nothing — and Finder file-drop creation; the attach path
deliberately doesn't clear, and cross-board arrivals and New Lane stay
outside the seam (a transfer isn't creation; a lane can't be born
invisible). An open inline rename now survives the filter hiding its
card: the model already kept the editor, but the field renders in the
card's slot, so renderedCards keeps the renaming card's slot exactly as
long as the editor is open — the query stands throughout, and commit or
Escape lets the predicate apply in the same pass. Verified conformant
and newly pinned: query-emptied lanes keep their slot with a 0 badge,
pasteboard staleness (takeover before paste and mid-staging both no-op),
out-transition reachability and the strip pre-divide hold by
construction with comments citing their rulings.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
04's settled clauses were mostly shipped already — the create landing
resolved through DropSlotMath.cardSlot with one nominal shadow per
importable file — but a release on the lane header fell through to the
card zones, which clamp inward, so a scrolled lane could propose behind
the header stripe. FileDropZones now folds header, attach hit-test, and
card-slot resolution into one pure seam asked in that order, the header
answering topmost per the ruling; lane headers register their frames
for it. FinderDrop.shadowCount names the floor-at-one rule. New tests
pin the header boundary, a differential against cardSlot's own zones
(same zones, not similar), and a store-level differential proving a
file landing takes the very ranks a card move there takes.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
04's ruling makes the drag the pointer's delete gesture: the shown
trash column accepts live same-board card drags, the shadow pinned
topmost — honest, since the trash sorts by deleted newest-first — and
release tombstones through the same write path as Backspace, extracted
so the two gestures cannot drift. DropTarget grew a container case for
the quasi-lane (it has no lane id by construction); lane drags,
cross-board arrivals, option-copies (re-checked at release, the one
input that can flip without a callback), trashed-side payloads, hidden
trash, and the read-only lock all refuse — and a refusal falls through
to the strip retarget, never cancelling the drag. The settle draws the
tombstoned rows in the trash under the cards' own GUIDs, so the echo is
an invisible content swap and nothing winks out for a round trip.
Selection needs no surgery: the reload's resolve rule ejects tombstoned
members as the vanish it is, pinned by a test contrasting both gestures.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
03's resettlement reverses the pathfinder carry-over: the
selection-keyed dual presentation proved undesirable, so a card has one
presentation — selection changes styling, never geometry, and the
masonry never reflows on click. Deleted the carousel view (page dots,
glass underlay, scroll-tick monitor), the QuickLook thumbnail cache
(sole consumer), the pure paging/suppression rules, and the
sole-selected animation key — Motion now keys transactions on the
search query and the drop proposal only. The attachment chip stays as
the face's whole attachment story; viewing media is the card window's
job. No carousel state had leaked beyond the view layer.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
03's sharpened settle rule: rendering the arrangement means rendering
the card — at release the shadow swaps for the dropped card(s) drawn in
place immediately, the appear never waiting for the echo reload. The
committed hold now carries the landing (ids, payload titles, operation)
and surfaces read one DropLanding seam: within-board moves draw the
real faces at their proposed slots under the arriving card's own key,
so the echo is an invisible content swap; cross-board card arrivals
draw payload-titled faces keyed positionally, so the echo reads as an
ordinary arrival. Cross-board lane arrivals deliberately keep their
shadow until the echo — a lane's face is a whole column with no honest
payload equivalent. The 1500 ms failed-write timeout is now seamed
(injectable duration, extracted expire) and pinned by tests.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
04's settled ruling: the attachment model is flat top-level files, so a
drag containing only folders never engages — no highlight, no proposal,
the standard incompatible-payload cursor — and a mixed drag proposes for
its files only, importing them at the drop while a loss row names the
skipped folders. Hover reads the providers' registered types (anything
conforming to public.directory refuses, packages included); commit
re-partitions authoritatively from the filesystem, so a synthetic
payload that hides its type still can't land a folder. The create path
now only ever fires with at least one importable file — the
mint-fail-remove dance is gone from the folder case and stays reserved
for genuine mid-batch failures.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
02 rules the trashed side has exactly one definition: the set with
trash rows — a card carrying its own deleted: under a tombstoned lane
is in neither universe, so an anchor or selection can never survive on
an item that renders nowhere. The membership rule now lives once, in
Liveness.walk, and ItemReferenceSet.idUniverse, TrashModel.entries,
paths, and emptyTrashTargets all derive from it — the old
lane-OR-card logic that admitted subsumed cards to the trashed side is
gone, and the two universes deliberately no longer partition the
board. Put Back, Delete Immediately, and Empty Trash outcomes are
unchanged: a tombstoned lane still moves and purges whole, its nested
tombstones with it.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
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 copy now walks the source tree item by item, checking cancellation
between items, and the in-progress banner row carries its promised
Cancel — a cancelled duplicate removes the partial sibling and never
happened (DESIGN/03 > File menu). A sandbox permission refusal of the
silent Finder-style sibling falls back to an NSSavePanel pre-filled with
the parent folder and the copy name — the panel's grant is the sandbox's
own answer; cancelling the panel cancels quietly, and non-permission
failures keep the ordinary one-shot banner. Refusal classification is
deliberately narrow (NSFileWriteNoPermissionError itself, no underlying-
chain walk) so an unreadable source never masquerades as a destination
refusal. Directories are created writable first with mode and timestamps
restored after the subtree lands, so a read-only source folder can't
strand its own copy. BoardDuplicatorTests grows from 9 to 18 tests.

02 ratified a warning-tone class for non-failure losses — content that
didn't arrive though nothing failed: a degraded paste, folders skipped
from a Finder drop, their future kin. Loss rows take the one-shot's
dismissable-untimed lifecycle (a loss the user didn't notice is the
harm) and rank below the true failures, above commit and attachment
notices. BannerCenter grows LossBanner, postLoss, and the
skipped-folders phrasing; the degraded-paste notice moves off its
signpost onto the new class, ending its too-quiet ranking.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
The committed placeholder's lane slot now takes the arriving card's
identity — .awaitingArrival keys as card:<id>, so when the echo reload
lands the ForEach sees one persisting element whose content swaps from
stub to card face instead of a removal and an insertion with two
scale+fade transitions (DESIGN/02 > overlays: the handoff must read as
one arrival). The awaiting face renders the card's exact chrome from
shared CardFaceMetrics, so any residual branch crossfade is between
pixel-identical renderings; the editing phase keeps its constant key so
typing identity holds. Slot position math is untouched.
CreateHandoffIdentityTests pins the key derivation.

The trashed-side gesture surface was sized to the rows' fitted height, so
blank column space below the last row couldn't arm a marquee — a dead
zone the board side doesn't have (DESIGN/04 > The trash: the column's
gesture surface is full height). The rows content now takes
maxHeight: .infinity like LaneView's scrollableCards, the identical
structure in the identical position, so the band arms from anywhere in
the column.

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.

The 2026-07-28 realign card asks the four caret chords (Move Left/Right,
lane-width pair) to yield to any focused text control. The seam already
conforms — caretChordsYield covers the board popover, the search field's
first-responder tracking, and card windows publish no scope — but had
zero regression coverage. CaretChordTests pins the rule: scopeless
windows never yield, either surface suffices, and inline editors remain
acceptsBoardMutations' concern, not this seam's.

The strip's standard-width division read the drop registry's strip
frame during body evaluation, but the registry is deliberately
unobserved (it exists for event-time reads): the first body ran
against a zero frame, every lane collapsed to the 1pt floor, and
nothing invalidated the view when the real measurement landed — the
board stayed corrupted until an unrelated re-render. The layout now
reads the GeometryReader's live proposal (reactive by construction);
the drop delegates keep reading the registry at event time.

The card face's in-place expansion (03-board-ui.md § Card face): a card
with attachments, as the sole selection, grows a paged media band below
its title; every other state stays compact behind the quiet paperclip.
- CardCarousel owns the pure rules: the sole-selection predicate decides
by identity (a sole-selected lane matches no face, no snapshot walk),
and expansion is suppressed outside the animation key while a rubber
band is active — a band names a set in progress, so carousels neither
flicker nor animate under it.
- QuickLook thumbnails generate off-main into a per-window cache keyed to
survive reselection, with the Finder-icon fallback while loading and
for non-previewable types; pages ride the platform paging behavior,
dots (glass underlay, solid under Reduce Transparency) click to page,
and a local wheel monitor turns a discrete tick into one clamped page —
precise trackpad pans fall through untouched.
- The expansion animates under Motion's new carouselExpansion transaction
keyed narrowly on the sole-selected card; Reduce Motion goes instant.
Drop-slot math and the marquee read the expanded height for free — both
re-register on every size change.

The remaining rows of 11-command-nexus.md § Context menus, every entry a
twin of an existing command path, never a parallel implementation:

card alone), Rename (Board ▸ Rename's beginRename path), Style… and the
quick-style recents (already present), Delete (File ▸ Delete's
store.delete on the standard widened target — selection when the clicked
card is a member, else the card alone).
- Lane (one menu, header and empty space): Rename and Delete join the
existing Style…/recents/Width rows, in table order.
- Trash entries and welcome recents verified already exact against the
table; the attachment row's menu is marked for m6 beside its command.
- File ▸ Reveal in Finder gains its board-window scope, the branch the m4
comment deferred here: the selection's folders on either side of the
trash boundary — enabled under every lock, inspection being a read — or
the board root with nothing selected; a selection resolving to no
folders disables rather than guessing.

Nexus parity, audited row by row (11-command-nexus.md § Menu commands) —

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).

AppModel.shouldRestoreAtLaunch gate; the Settings pane's caption rides a

The board's live title+body filter per 04-interactions.md § Search:
- SearchFilter — a pure value folding the query once (case- and
diacritic-insensitive substring, locale-stable); title OR body matches,
attachment filenames never searched; only the literal empty string is
inactive.
- One universe: the filter threads through SelectionGrammar's order lists
as a defaulted parameter, so ranges, Select All, arrow navigation, the
marquee, drop zones, count badges, and the shown trash all read the same
filtered set by construction; lanes are deliberately never filtered out
(an emptied lane keeps its slot with a 0 badge). Hidden cards leave the
selection through the existing constrain primitive, run on every query
change and as the last line of the reload resolve; the delete successor
is filtered so ⌫ never selects a hidden neighbour.
- The field: an NSSearchField-backed toolbar item (the toolbar's sole
default item); Edit ▸ Find ⌘F focuses it through a focused-value
presentation; stock field-editor dispatch — Return swallowed, Tab is the
keep-filter path to the board, board commands stay enabled except the
caret-chord pair, now one shared caretChordsYield expression.
- Escape is staged: clear the non-empty query (focus stays), hand an empty
field back to the board, clear an active search from board focus —
before Escape's clear-selection meaning.
- Creating a card clears the search (the placeholder funnel); a rename
deliberately gets no carve-out; filter reflow rides the content spring
keyed narrowly on the query.

⌘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.

Files from Finder land on the board per 04-interactions.md § Drag & drop:
- Dropped on a card, they copy into its attachments/ (any type, multi-file),
the face highlighting while hovered; the hovered card is resolved by
hit-testing the same analytic masonry frames the card zones are built
from, so attach-beats-create adds no drop region and cannot drift from
the dispatch.
- Dropped on lane empty space, one card per file — filename minus extension
as the title (a blank stem omits the key), fresh GUID, rank at the drop
position through the ordinary insertion machinery, the file attached —
all in one bracket; a failed import removes the just-minted card, so
creating-then-abandoning never leaves an empty card behind.
- Every board drop surface now declares .fileURL beside the two board
types (the single-target-dispatch rule); tombstoned surfaces are inert;
file sessions ride a distinct session mode with their own watchdog and
no hysteresis, leaving the board-drag machinery untouched.
- Also: four empty fixture directories pinned with .keep files so git
preserves them, and a test-only visibility fix in DragSessionTests.

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

DESIGN edits landing from the parallel session, honored:
- Caret chords yield to any focused text control (04 ▸ Grammar): Move
Left/Right ⌘←/⌘→ and the width pair ⌥⌘←/⌥⌘→ now disable while the board
popover is open — its fields are the one non-inline text surface a board
window has today; the search field and card-window fields extend the rule
with their own cards.
- The width pair batches over a multi-lane selection (03 ▸ Lane, the styling
precedent): each selected lane steps one unit through one bracket
(stepLaneWidths); floor members hold on a decrease; the context-menu
stepper stays single-lane by nature.
- A width write landing on 1 removes the width key (03 ▸ Lane, the
remove-at-default family), every mechanism alike — writeLaneWidths is the
one commit point; a hand-written width: 1 is preserved by the unchanged
guard until the app itself next edits width.

The pathfinder's drag-reorder model, ported and generalized (DRAG-REORDER.md
travels with it, rewritten for lanes, the interior masonry, multi-drag,
cross-board sessions, the re-grounding trio, and the committed-overlay hold):
- DropSlotMath — resting-layout zones from analytic lane arithmetic and the
pure masonry placement (MasonryLayout now lays out through the same
MasonryPlacement the drag reads, so geometry cannot drift), span-capped
triggers sized to the dragged run's future footprint, hysteresis holds with
the fresh-entry fallback, boundary ties, own-slot no-ops; nil means hold.
- DragAutoScrollMath — the activation bands and velocity ramp, pure.
- The drop commits, one performWrite bracket each: moveCards/copyCards within
a board (insertion ranks touch only the dragged cards; renumber fallback);
receiveCards/receiveLanes/receiveRestoredCards on the destination store for
cross-board copy and ⌘-move with the import-boundary remint, lane copies
stripping tombstoned cards while moves carry them; restoreByDrag is now
positional, writing order only when the drop names a new one.
Gestures, sessions, previews, and delegates are the second half.

The board's fixed grammar keys and the menu-backed chords of
04-interactions.md § Keyboard, per the Command Nexus inventory:
- Spatial arrow navigation (NavigationMath.nearest over the marquee
registry's frames — one geometry source), walking across interior
masonry columns, lanes, and into the shown trash; ⇧-arrows extend via
the same range function as ⇧-click and go inert at the liveness and
kind boundaries; ⌥-jumps with the ⌥↑ lane-domain escalation and ↓

- Delete now selects the Finder-style successor sibling from the
pre-write snapshot, so repeated ⌫ walks down a lane; external
vanishing still only shrinks the selection.
- handleReturn rejects modified Returns; the trash column renders
eagerly so every row stays registered for navigation and the marquee.

The full pointer grammar of 04-interactions.md § Selection, stated once
as a pure function (SelectionGrammar) and reached through one store
funnel from every click surface — card face, lane header, lane empty
space, trash row:
- Plain click replaces and anchors; the lane surfaces (header and empty
space alike, per the settled one-lane-click-behavior rule) toggle off
on a sole-membership repeat.
- ⌘-click toggles within a homogeneous set; crossing any axis — cards
XOR lanes, live XOR trashed, card entries XOR lane entries in the
trash — degrades to a replace, so no click can produce a mixed
selection.
- ⇧-click ranges from the anchor in the (side, kind) order list: flatten
order for cards, lane order for lanes, the trash's deterministic sort
filtered to kind — the pointer twin of the keyboard's boundary rule
(the keyboard goes inert, the pointer skips).
- The rubber band (MarqueeSession/MarqueeMath) arms from lane empty
space, the board backdrop, and the trash column; side frozen at the
origin, trash bands homogeneous by topmost kind, frames self-registered
in strip space, geometric begin guard, never animated.
- Fast plain double-click opens the card window (⌘↩'s pointer twin);
Select All answers the standard Edit menu item via the responder
chain, trash- and kind-respecting.
- The range anchor lives in TransientBoardState beside the selection and
obeys the same reload vanish rule.

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 named home for every curve and duration — the two-voice split 03
fixes (snappy structural: drag reflow 0.18, delete 0.25, lane resize
0.2; smooth content-reflow 0.28), the scale-and-fade appear/disappear
transitions (cards 0.8, lanes 0.9), and a Reduce Motion variant on
every accessor (animations go instant, transitions go crossfade). A
post-migration grep holds the invariant: zero motion literals outside
Motion.swift. The animate-vs-snap split lands where Lanework's
one-way flow puts it: the store's reload seam. An app-mediated echo
applies its snapshot inside the structural transaction; foreign and
reconciling reloads — and every bracket-ending wholesale reload —
assign bare, because live-reload is the board becoming what's on
disk, not an event to perform. A window that merged foreign events
into an app-mediated span animates, deliberately: the ratified merge
rule makes it indistinguishable from a pure echo, and a test pins
that reading so a future mixed case fails loudly. The lane-reorder
reflow keys on the drop proposal alone (pointer tracking stays 1:1),
the resize session freezes its Reduce Motion answer at drag start so
the unit tick and the window resize can never disagree, and the m5
drag / m5 search / m7 undo voices are named seams waiting for their
call sites. 13 new tests.

The corpus just ratified the plural case: a multi-selection anchors
at its last member in flatten order (lane order, then card order —
the multi-drag order, the same anchor paste will use), so creation
follows the last selected card or appends to the last selected lane
instead of falling through to the last-active lane. One display-order
walk keeps the resolver pure; the sole selection is now just the
degenerate one-member case.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
Deletion becomes a two-stage, Finder-style story. File > Delete and
plain Backspace tombstone the live selection; View > Show Trash (no
chord — Shift-Cmd-T stays with the system's tab bar) reveals the
quasi-lane: trailing, one fixed width unit consumed only while shown,
hatched dimmed header, count badge, no new-card button, exempt from
resize and reorder alike. Its contents are a pure view over the
snapshot — the deterministic sort (deleted newest first, folder-name
ties, unparseable stamps oldest) interleaves card rows with a
tombstoned lane's single entry, whose count names what Put Back
returns; the ancestor walk is absolute, so an own-flag card beneath a
tombstoned lane has no row and recovery is deliberately two steps.
Put Back twins Delete on Cmd-Backspace with validation enabling
exactly one; restore fidelity is byte-perfect because nothing ever
moved. Delete Immediately confirms exactly where loss is real (every
board is mode-none today; the predicate names the git carve-out for
m7), Empty Trash always confirms with the true whole-board count,
and dragging a tombstoned card onto a live lane restores it there —
positional drops and cross-board locality arrive with m5's machinery.
The banner's delete phrasing drops "move to the trash" per the naming
constraint: board deletion says Delete, "Move to Trash" stays
reserved for the system Trash. 47 new tests.

The window-title widget arrives as a leading titlebar accessory — a
quiet chevron on board windows only, installed and removed by the
window controller's own attach lifecycle — anchoring the one
board-level surface as a transient popover (the board window
deliberately grows no toolbar item for it). Inside: board rename
editing frontmatter title only (the folder is never renamed; an empty
commit removes the key and the window title falls back to the folder
name), the embedded shared style editor permanently targeting the
board, and the labeled Git section that this milestone only reserves
— a mode-none explanation and a disabled stub where m7's add-git,
branch, remote, and authentication controls land. Cmd-I (File >
Board Info) toggles it per window through a focused scene value,
kept apart from board-scoped transient state since a titlebar
popover belongs to one window, not to the board. Escape reverts a
dirty rename field and falls through to dismiss otherwise; a foreign
rename resyncs the field only while unfocused. 12 new tests.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
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.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
The design corpus ratified that ranges are part of a sensible reading:
an exact-integer width below 1 now coerces to 1 read-side (bytes
untouched) instead of reading as malformed — the width division must
never see a zero or negative unit — while a non-finite order (.nan,
.inf) is now the same loud malformed-order rejection as a non-numeric
one, guarded at the single point where the double arrives so loader
and Writer inherit it together. The symlink-never-traversed rule
turned out to be already enforced (the loader has filtered symlinks
ahead of the directory check since the first commit); it and the
copy-preserves-the-link-verbatim behavior are now pinned by tests,
alongside the two hostile shapes the corpus names (width: 0,
order: .nan). Five new tests.

The card face becomes real: leading SF Symbol (card default doc.text,
tinted by a valid hand-written iconColor — schema yes, control no),
title or the quiet untitled placeholder, and a quiet paperclip when
the card has attachments — title-only by design, no body excerpt.
Color is the settled K1 edge accent, not a fill: background paints a
4pt stripe down the left edge, resolved through the ported pathfinder
palette (12 icon tints + 12 backgrounds carried over verbatim, plus
raw #RRGGBB[AA]); anything unresolvable paints nothing and stays on
disk exactly as written. The snapshot now carries each card's flat
attachment names — the loader's one read inside a card folder, shared
with the Writer's listing so the m5 carousel and m6 sidebar can never
disagree on order (Finder order, the Writer's existing comparator).
The face keeps its top-aligned structure so the sole-selection
carousel can expand inside the card without moving masonry neighbors.
18 new tests.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
The lane title bar becomes real: leading SF Symbol (hand-written names
render leniently, unknown ones fall back to the level default), title
or secondary untitled placeholder, a quiet count badge that counts
exactly the cards the body renders (so the m5 search filter is
followed by construction), and a new-card button. The whole bar is
the reorder drag surface — no grip — with click-vs-movement splitting
select from drag; a pure proposal function maps the drag to an
insertion index and release commits through the Writer's same-parent
degenerate reorder, compacting and retrying when midpoint precision
runs out. Clicking never edits: inline rename is Return on the sole
selected card or Board > Rename for either kind, a third transient
editor beside the placeholder that tracks its target by UUID, commits
on focus loss, discards silently when the target vanishes, and
removes the title key on an empty commit. The new-card placeholder
renders at last — the settled Cmd-N target rule (pure, tested) files
it after the anchor card, at a selected lane's bottom, or into the
last-active lane; Return commits and re-selects the lane, Cmd-Return
also opens the card window, and a failed create discards the overlay.
New Card / New Lane / Rename land in the menus with focused-editor
and read-only validation; rename gets its own WriteOperation case in
the banner vocabulary. 59 new tests.

The lane strip replaces the placeholder board: window width divides
across the lanes' width units (no horizontal scroll, no minimum width,
degenerate compression accepted), a lane of n units flowing its cards
into n round-robin masonry columns via a measurement-cached Layout.
Width has two deliberately opposite controls, both landing here: the
right-edge drag (ported verbatim from the pathfinder's ColumnResize)
freezes the 1x standard at drag start, snaps between integer widths
with the asymmetric shadow-leads tick and 10pt re-entry, grows the
window one standard width per snap so siblings keep their exact
pixels, and rubber-bands at the screen's visible frame — uncapped
otherwise; the Increase/Decrease Lane Width items (new Board menu,
Cmd-Opt-arrows) are the stepper's keyboard face and re-divide the
existing window width instead, never touching the window. Width
changes write through the new .resize WriteOperation ("Couldn't
resize…" in the banner vocabulary, which grows with the surfaces by
design); malformed width values render as one unit and stay untouched
on disk. 27 new tests port the pathfinder's resize-math suite onto
the uncapped range and pin the write path's fidelity.

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.

- 02: failed create discards the placeholder; a second creation is a
click-away for the open draft (replace-with-discard, ⌘N unreachable);
unwritable-lock banner names volume vs permissions; WriteOperation
vocabulary grows with rename/body-save surfaces; one bookmark per open
board threads through the open flow; in-progress banner class ratified
newest-first; signpost lifecycle is the dismissable untimed one-shot

Two follow-ups to this session's decisions: the reconciling reload's
writability re-probe now raises the unwritable lock as well as clearing it
(fail loudly once, not per gesture), and under the shape-only identity
predicate the loader deterministically dedupes case-spelled sibling twins
on case-sensitive volumes (lowercase spelling wins, else lexicographic
first; loser takes the stray posture) so a snapshot never carries
duplicate ids.

Researched against the Frontmatter implementation: the duplicate-key
rescue's retry-loop pattern (compose a placeholder-patched copy, derive
spans from original lines) extends directly. Ratified: a top-level key
line whose plain unquoted remainder trips "mapping values are not allowed"
reads as everything after the first ": "; quoted/flow remainders and
nested shapes stay fail-fast; bytes preserved, fully editable, heals on
first app write of the key; silent with a log line. Test obligation named
(no hostile-YAML case covers the shape today).

- 02: welcome counts are live items only; failed first opens still record;
duplicate-identity registry records merge silently (newest wins);
BoardStore's FolderWatcher pointer reads "below"
- 11: lane-header new-card button inventoried (click names its target lane,
overriding 04's ⌘N rule — cross-referenced there); attachments quiet-add
affordance listed as a twin; Undo/Redo and Pull/Push rows gain the
abnormal-state pause, read-only lock, and unresolvable-remote conditions;
welcome scope added to Reveal in Finder
- 03/11: one lane context menu (header or empty space) with the full
inventory, replacing the split rows
- 09: instantiated boards are never in git mode — actual mode follows
detection at the destination (repo-nested possible)
- 08: the app never writes an existing CLAUDE.user.md; one-time rescue
creation stated as the exception

TransientBoardState, one per store, holds state by how a reload treats
it: item-referencing sets (selection, drag membership, pending cut)
share one shape and one constraint rule — members must exist in the
current universe — applied in two directions by one primitive, so the
search filter's hidden-cards rule and reload survival are one rule
expressed once; derived state is stored as its inputs only (the query,
never its result set); and the new-card placeholder is a lane-anchored
overlay with no UUID until commit, discarded when its lane vanishes or
tombstones, handed off when the created card's UUID appears. Trash
visibility rides along per-open, never persisted. The decision is
written back into DESIGN/02 § Changes from Kanban — the TBD is closed.

The composer was a pure snapshot diff while the repo tracked files outside
the model (agent guide, strays, .gitignore), leaving stray-only windows
uncommittable and the guide's own subject underivable. Settled: the
committer stages the whole root with the tree as its commit condition; the
composer also receives the changed-path list, composing "Update agent
guide (vN)" (version from the marker line) and "Update '<path>'" events
that ride as body bullets under model-event subjects; attribution falls
out of the path-keyed EchoLedger.

The detached-HEAD/mid-merge pause named auto-commit, Undo/Redo, and branch
controls but left Pull, Push, and push-on-commit live — against a dirty
tree whose clean-by-pull-time invariant the held auto-commit had falsified.
Settled: the whole surface pauses; the ahead/behind badge keeps counting
since a fetch is a read.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Show Trash's ⇧⌘T collided with the Show Tab Bar item macOS injects into
multi-window apps. Settled: tabbing is kept as a system affordance (each
tab a full board window, per-board frames applying when standalone) and
Show Trash ships with no default chord, assignable via the remap path.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The field's exits were commit-only, silently diverging from the board
rename's Escape-abandons rule, and Escape was ambiguous with the body in
Edit mode. Settled: Escape reverts to the on-disk title and focuses the
body; the collision resolves by focus per 06's first-responder routing.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The trash trio had no verbs — tombstoning and purging both composed
"Delete card 'X'", erasing the moved-to-trash vs gone-forever distinction
the docs ask users to learn. Settled by diff shape alone: deleted:
appearing = Delete, clearing = Restore, item leaving the tree =
Permanently delete; plural folding keeps Empty Trash distinct from a
multi-select delete.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The rubber-band had its boundary sentence; the keyboard extend gesture had
none. Settled: a ⇧-arrow that would cross live↔trash or card↔lane-entry is
inert — never move-and-replace — keeping the homogeneity invariants
unbreakable by keyboard while plain arrows still walk across.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Paste's anchor rules never accounted for a tombstoned selection, and a
literal reading filed a pasted lane beside a trashed card's on-disk lane.
Settled: ⌘V stays enabled and behaves as with nothing selected (card
payload to the last-active lane, lane payload to the board's right end).

The fixed grammar keys were formally live over the board while the search
field had focus, letting a reflexive Return fire rename/create and destroy
the query. Settled: every key acts on the field (no pass-throughs), Return
no-ops, Tab moves focus to the filtered board with the query intact, and
Escape stages — clear query, then exit field, with board-focus Escape
clearing an active search before its clear-selection meaning.

Accept liberally, emit conservatively (764a4d4): the gate is 8-4-4-4-12
hex in any case and any UUID version — uuidgen and UUID().uuidString
print uppercase, and a strict lowercase gate would silently stray an
agent's standard-tool card. Identity comparison is UUID-value equality
everywhere: ItemID keeps its byte-faithful rawValue but equates and
hashes on the lowercased canonical form, and the writer's
import-boundary collision check canonicalizes, so a same-UUID arrival
spelled in another case remints instead of slipping past. The app still
mints only lowercase v4 and never renames to canonicalize.

Every lane command keyed off "a selected lane" with no drag-free way to
create one. Settled: ⌥↑ with the lane's first card selected selects the
lane (↓/⌥↓ descend back; ⌥↑ then inert), an empty selection seeds at the
first lane's first card, and a plain click on the lane title bar selects
with the drag surface engaging only on movement.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The row's name and icon implicitly required reading each recent board's
root index.md at welcome time — the hang the counts rule was written to
avoid. Settled: title/icon/iconColor live in the registry record; they
refresh whenever an open board's reload changes them (in-app renames land
instantly, foreign renames of open boards ride along), with closed-board
renames stale until next open like the counts.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The banner surface as one vocabulary (Kanban/LiveStore/BannerCenter,
Kanban/UI/BannerStripView): a pure precedence rule — in-progress pinned
above the collapse (ratified mid-build), lock > breakage > one-shot
write failures > commit+attachment, signposts last — with all
user-facing phrasing owned here via exhaustive switches over the closed
WriteOperation enum; free-form English survives only in diagnostics.
performWrite posts its failures before rethrowing, so no one-shot can
bypass the strip; refusals under lock post nothing.
The lock vocabulary completes: vanishedRoot and unwritableLocation join
bracketedReloadFailed, each with its own clearing rule (unwritable
clears only on a reconciling reload's writability re-probe). The
registry now owns root recovery: bookmark re-resolution absorbs renames
transparently, a dead root locks read-only and re-arms FSEvents on the
gone path so the root's return round-trips back through rootChanged,
re-minting and re-keying on the way. DirtyBufferGuard is the one modal
moment, retry / save a copy / discard, no fourth button.
36 new tests; full suite 333 tests in 62 suites green. Five findings
filed on the Redesign board.

Both whole-board copies were absent from the lock's command enumeration,
staying enabled while the source tree was gone, unknown, or unwritable and
while the lock suppressed their required close flush. Settled: Duplicate
disables in every lock state; Save as Template disables except under the
unwritable-location lock, where reading the board into Application Support
is a legitimate copy-out with a vacuous flush precondition.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The stacking order covered only error classes, letting an in-progress row
collapse behind "+N more" — the sole explanation of a bracket's write lock
and a deferred close. Settled: in-progress rows pin above everything,
exempt from and uncounted by the collapse; the passive remote-change
signpost ranks below all error classes and may collapse.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The trash's newest-first order is load-bearing for keyboard input, but
same-second multi-deletes and 01's blessed-unparseable timestamps had no
ordering. Settled: ties break by folder name ascending; date-unknown
entries sort as oldest, after all dated entries; lane entries interleave
by their own stamp.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
01 said "lowercase UUIDv4" without defining the test, and the strict
reading made every uppercase uuidgen/UUID().uuidString folder a silently
skipped stray. Settled: 8-4-4-4-12 hex in any case and any version is an
identity; comparison is UUID-value equality (case-spellings are one
identity, matching default-APFS behavior); the app emits lowercase v4
only and never renames to canonicalize.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The registry recorded recency but not which boards were open at quit.
Settled: each record carries an open-now flag set on open and cleared on
user-initiated close only — quit teardown leaves it standing, so there is
no at-quit write and crash recovery falls out for free. Restoration
reopens flagged records by lastOpened order; the preference only gates
consulting the set.

10 recovered focus "to the card's lane" even in its own lane-tombstone
case, where that lane renders nowhere. Settled: recovery walks up then
sideways — the lane at the vanished lane's position (next by order, else
previous), board container only when no lanes remain, never into the
hidden trash; the announcement names the lane, not the card.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
10 promised toggleable-without-pointer, 11's normative inventory had the
toggle as pointer-only, and 02's lock disabled it "via menu validation"
with no menu item to validate. Settled: checkboxes and links are real
controls in the focus/accessibility tree — FKA + Space and VO-Space toggle
them; in-content controls are content, not commands, so 04's menu-item
contract and 11's existence rule scope to commands; under the read-only
lock the controls disable in place.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
03's Put Back cascade ("restores the lane too") was unreachable dead text
under 01's hide-the-subtree consumer rule and 02's effective liveness.
Settled: the lane's single trash entry subsumes everything beneath it; its
count is what Put Back returns to the board; lane Put Back splits by flag
(hidden-with-lane cards return, individually tombstoned ones reappear as
trash rows), making that recovery deliberately two steps.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
04's drag rule called a within-board lane duplicate unsupported while the
clipboard rules quietly permitted it via same-board lane paste. Settled in
favor of the clipboard: the duplicate is supported there (fresh GUIDs,
tombstones stripped, no menu-validation special case) and merely not
available by drag — ⌥ stays ignored on lane drags so the gesture remains a
clean reorder.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
01's table promised an update on every app write, which raw-source Apply
(byte-for-byte contract) and attachment operations (never touch index.md;
load-bearing for 03's Add-Attachment-during-raw-source rule) cannot honor.
Settled: modified updates only on app writes that rewrite the item's
index.md; both exceptions stated as deliberate, and the stale-readout
consequence on 05's Modified line accepted with attachment history living
where the files do.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
06 and 10 consumed a per-file app-vs-foreign classifier that 02's component
inventory never named and whose layering prose seemed to deny. Settled: a
new EchoLedger component records each BoardWriter operation's expected
outcome (content hash / absence / move pair); final-content matching
classifies each observed file, deciding both races (byte-identical foreign
write → app-mediated, accepted; same-window foreign overwrite → foreign,
last writer wins). Ledger is in-memory and per-store; launch catch-up is
all-foreign; bracketed operations bypass it. "Trusts its own writes no more
than anyone else's" is scoped to rendering; BoardWriter's no-hidden-state
bullet stands.

WriteOperation replaces free-form operation strings throughout
BoardWriter, per the settled rule in 02 § Write-failure surfacing: the
banner layer will switch exhaustively over it, so a new operation
without a banner rendering is a compile-time hole. Titles enrich at the
two points a document read makes them known (updateIndex, and the
move/copy pre-flight), so failures after the read name the item;
purge never reads and stays title-less. Free-form English survives
only in the diagnostic reason.
Full suite 300 tests in 56 suites green.

The parallel design session settled the tombstoned-ancestor question:
a card counts as trashed if its own flag or its lane's says so, so
tombstoning a lane ejects its cards from a live selection — they render
nowhere once the lane collapses to a single trash entry, and nothing
invisible may stay selected, drag-included, or pending-cut. One-line
predicate change in Selection.resolved(against:), plus the test.
Full BoardStore suite green (15 tests).

Two registries (Kanban/LiveStore/): BoardStoreRegistry shares one live
store and one started, fully wired watcher per open board across its
windows — keyed by file identity (fileResourceIdentifier), never path,
refcounted to order teardown; release matches by store identity so a
board renamed while open can't leak its watcher. BoardRegistry persists
app-private per-board state in Application Support as diff-stable JSON:
records anchored by security-scoped bookmarks, recents = the registry
sorted by lastOpened (counts registry-cached, never scanned), graceful
orphaning with Forget, corrupt files quarantined aside, and files-first
verified — the board tree is untouched byte-for-byte. Timestamps use
ISO8601DateFormatter with fractional seconds: the FormatStyle variant
truncates-then-rounds and drifts a millisecond per round trip.
16 registry tests; full suite 297 tests in 56 suites green. Four
findings filed on the Redesign board.

Tombstoning a card's lane ejects the card from selection, drag
membership, and the pending cut - liveness is ancestor-walked, since
the card renders nowhere once 03 collapses the lane to a trash entry.
BoardStore's bullet now says it coalesces reloads (one walk in flight)
while the debounce lives in FolderWatcher, matching m3 as built.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The next-reload-or-lock expectation arms on every bracket exit, thrown
operations included - a mid-flight failure is when the tree's state is
least known, so the mandatory final reload runs regardless.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
The parallel design session resolved the m3 watcher findings; two
changed behavior: .git internals are now filtered at any depth (a
nested clone or submodule is a stray whose internals never render),
and a root change landing mid-bracket is owned by the root-change
path — endBracket() skips its mandatory reload once a .rootChanged
tore the stream down, cleared when a fresh stream attaches. The skip
is scoped by an explicit flag, not by stream absence: a watcher whose
stream never came up still delivers post-bracket reloads, since
distrust of FSEvents delivery is the mandatory reload's whole reason.
Two new watcher tests; full suite 281 tests in 54 suites green.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
Per-board @Observable MainActor hub (Kanban/LiveStore/): watcher signals
drive off-main tree walks with a generation guard, single-flight
coalescing (strongest pending origin, watcher's merge rule), and the
resilience contract — a failed reload never replaces a good snapshot,
per-file breakage never locks editing, and a wholesale operation
(performWholesale) arms a reload-must-succeed-or-lock floor so a failed
post-bracket reload flips the board read-only until a good reload heals
it. Selection is a pure UUID-set value re-resolved on every swap;
liveness flips eject. performWrite brackets the watcher so Writer
round-trips come back app-mediated.
14 store tests; full suite 279 tests in 54 suites green. Three findings

Contradictions: v1 gains a minimal Settings pane (⌘,) housing the
restore-at-launch toggle; Window ▸ Welcome to Lanework inventoried in 11.
Gaps: close/quit waits for in-flight bracketed and copy-shaped operations;
pull extends the Edit-session treatment to open raw-source buffers
(signpost + last-writer-wins Apply); File ▸ Duplicate keeps tombstones
(01's "as-is" softened to per-flow exclusions). Minor: Undo routing
promoted to a real heading in 06; 11's dead "10 ▸ Actions" citation
repointed. m3 watcher findings: root-gone cancels armed debounced
delivery; mid-bracket root changes owned by the root-change path;
.git filtered at any depth; banked mid-bracket reconciles and the
200 ms debounce ratified.
Debounced FSEvents watcher over the board tree (Kanban/LiveStore/):
trailing 200ms debounce coalesces bursts; nestable brackets suppress
delivery and close with exactly one app-mediated reload; origins merge
reconciling > appMediated > foreign; missed-events flags degrade to a
reconciling reload; WatchRoot vanish tears the stream down (streams die
and are recreated — reattach() covers rename re-resolution); board-root
.git churn is filtered against the symlink-resolved root. The FSEvents
release callback must be top-level and non-isolated — a MainActor
closure traps in dispatch_assert_queue during stream deallocation.
15 watcher tests (4 consecutive green runs); full suite 265 tests green.
Five design findings filed on the Redesign board.

Four minor design-review findings resolved: appended frontmatter lines
adopt the file's prevailing line ending; empty-but-not-blank frontmatter
joins the readable-but-uneditable shapes; an interrupted renumber's
per-file partial is accepted; the write-failure operation becomes a
closed enum carrying the item title.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
- Appended frontmatter lines adopt the file's prevailing line ending
(read off the opening delimiter) — one stamp never produces a
mixed-ending file.
- Empty-but-not-blank frontmatter ({}, null, ~) joins the
readable-but-uneditable shapes: zero keys load fine, but appending
after that text would be unparseable YAML.
- Renumber is atomic per file, not per lane — an interrupted rescale
is accepted the same way as the shared-board burst: valid floats,
deterministic order, next renumber completes the job.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
The executable spec for BoardWriter's cross-cutting guarantees, in a
dedicated WriteFidelityTests.swift: minimal-touch verified down to
sibling mtimes across a seven-operation session; renumber pinned as
the sole exception (whole lane rewritten, board root / other lanes /
tombstones untouched); delete→restore byte-precise (only the modified
line differs, zero tombstone residue); unknown-key order preserved
with keys interleaved among schema-owned ones; and a composite
building a board purely through the writer, hand-editing a file like
an agent would, then moving/copying/deleting/renumbering to a
zero-warning reload. Guarantees already pinned by the per-operation
suites (atomicity, move/copy identity, body round-trip) are
referenced, not duplicated. Shared fixtures promoted to
WriterTestSupport.swift. README gains the write-side feature bullet.

importAttachments lands files into a card's attachments/ (created on
first import — the one folder the app ever makes there), never
overwriting and never refusing a name: collisions auto-rename
Finder-style, counting up from 2, with a same-named subfolder
blocking a name exactly like a file. Sources are validated before any
copy; a failed copy removes the partial destination and throws naming
the source file; a multi-file batch stops at the first failure with
earlier files staying landed. listAttachments is the flat surface:
top-level regular files only, Finder-sorted, subfolders and hidden
entries excluded and untouched; a missing attachments/ lists empty.

deleteItem writes deleted: <now> in place through updateIndex — the
folder never moves, nothing beneath it is touched (hiding the subtree
is the renderer's ancestor walk, not a stored flag). restoreItem
removes the key — position-perfect by construction, every duplicate
occurrence taken so a hand-written twin cannot resurrect the
tombstone. purgeItem physically removes the tree; an already-missing
folder is success (a Finder deletion converges on the same end
state), and no prior tombstone is required (Delete Immediately skips
the stage by design). Board-root deletion is structurally unreachable
via the UUID-shape guard shared with move/copy. Neither delete nor
restore polices liveness — re-deleting refreshes the timestamp,
restoring a live item is a harmless stamped rewrite.

moveItem: physical folder move, UUID and created travel unchanged;
exactly one file rewritten (the moved root's order, stamped). Import
boundary detected by resolved board-root comparison; on a cross-board
move-in, arriving UUIDs colliding with any identity in the destination
board (tombstones included) are reminted per folder at the finest
grain — folder rename only, file bytes untouched, every repair
reported in MoveResult. A colliding root moves straight to its minted
name. A same-parent move degrades to a plain reorder, self excluded
from the appended-rank scan.
copyItem: whole-tree copy minting fresh UUIDs at every depth; .fork
keeps created while stamping modified and clearing modified-by, .born
(template instantiation) stamps created fresh too. Nested uneditable
or unreadable files copy byte-verbatim rather than blocking the
gesture; the root must be rewritable. All-or-nothing at the
destination — any failure removes the partial tree.
24 new unit tests; 220 total green.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.

The single point through which every mutation becomes a filesystem
operation: read fresh from disk (strict byte-faithful UTF-8), refuse
readable-but-uneditable frontmatter shapes, apply the edit through the
span engine, stamp modified / clear modified-by, then temp-file+rename
atomically. Renumber-visible-children is the sole minimal-touch
exception, tombstones untouched. Structured BoardWriteError carries
operation + path + reason for the future banner surface.
Alongside, three edges the card surfaced:
- The loader now decodes byte-faithfully too, so a BOM'd or non-UTF-8
index.md is rejected at load per the encoding contract, instead of
loading via NSString's silent BOM strip and then refusing every write.
- An appended frontmatter line adopts the file's prevailing line ending
(a CRLF file stays uniformly CRLF when a stamp first lands in it).
- Empty-but-not-blank frontmatter ({}, null, ~) is detected as
uneditable — appending after it would be unparseable YAML.

Fills the gap: the rename editor follows its card by UUID through
foreign moves, discards silently when the target vanishes or flips
liveness, and a mid-search rename re-runs the predicate like any edit
— creation stays the search filter's only carve-out.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: wake/activation reconciling reloads, MustScanSubDirs and
overflow degrade to a full reload, dead streams are recreated at the
re-resolved root. Stale boards structurally excluded.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: eager staging at copy time, at most the current copy
kept (sweep at launch and each copy against pasteboard references,
surviving relaunch), and attachment-less fallback pastes surface a
one-shot banner naming the loss.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: resting zones recompute per snapshot (frozen inputs are
the dragged items' sizes and the pointer); proposals re-validate by
liveness with release-cancels-when-invalid; an emptied drag cancels
itself, partial vanishing drops survivors.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: on root-gone signals the bookmark re-resolves first —
success absorbs the rename transparently (watcher re-attach, URL and
window-key re-derive, full reload); only an unresolvable bookmark is
the vanished-root lock.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: Save All applies each raw buffer (a validation failure
cancels the switch, focus on the offender), Discard exits without
writing, Cancel keeps everything. External checkouts remain accepted
last-writer-wins per the dirty-buffer rule.

18 golden fixture boards as real on-disk trees under Fixtures/ — ten
valid/tolerated cases (rich board, interrupted create, non-UUID strays,
stray files, tombstones, tie-breaks, unknown-key order, coercion,
last-wins duplicates, board-level deleted) and eight fail-fast cases,
each pinned to its exact error reason and path; the rich board's whole
tree round-trips byte-identically. Pins two contract subtleties now
recorded in the design: tombstone flags are not inherited (renderers
walk ancestors) and last-wins resolves before order strictness. README
