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.

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.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
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.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
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.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
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.
Claude-Session: https://claude.ai/code/session_01SR4XGjmBE16ZUYWpfFHXwY
- 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
- 01: folder-name tie-breaks compare the canonical lowercase spelling
everywhere (Ranks and trash sort)
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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).
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
- 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.
Full suite 352 tests in 64 suites green. Two findings filed.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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).
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.

Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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).
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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
filed on the Redesign board.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.

The executable spec for BoardWriter's cross-cutting guarantees, in a

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.
5 new tests; 250 total green. Closes milestone m2-storage-write.

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.
