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
filed on the Redesign board.

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.
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.
11 new unit tests; 245 total green.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.
14 new unit tests; 234 total green.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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.

Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
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
gains the storage-foundation feature entry. 146 tests total.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
Fills the gap: pull/push/switch/restore share the auto-committer's lock
posture with a visible waiting state; clean failures are one-shot
banner errors; the never-mutate rule exempts the app's own stamped
leftovers, which it aborts and reports.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: foreign commits — auto-committed agent work and agent
self-commits — push onto the in-session stack as steps, with a
pre-flight HEAD re-sync before every undo/redo. One rule in-session
and across relaunch; arriving commits clear redo.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: the lock spans every window sharing the store — Edit
entry, raw-source Apply, attachments, sidebar actions, checkbox toggles
disable; drags out offer copy only. Open Edit buffers stay typable with
saves suspended; held text resolves by lock cause (switch/restore
settle first, post-pull buffer-wins, returned root saves normally).
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fills the gap: restores materialize only the current-vs-target diff, so
untouched Edit sessions are unaffected; a touching restore reuses the
branch-switch Save All / Discard / Cancel step. Redo symmetric;
raw-source buffers follow the branch-switch settle treatment.

rawValue and the coercion/malformed paths now stop at the quote-aware
inline-comment boundary, so 'title: 2048 # note' coerces to "2048"

Duplicates: Yams' duplicate-key error is disarmed by placeholder-
renaming first occurrences and re-composing (line count preserved, so
span layout stays exact); reads take the last occurrence, set()
rewrites the winner and clears earlier twins, remove() clears all.
Top-level only — nested duplicates stay YAML errors (doc updated).
Re-splice: an inline comment on a rewritten scalar line survives, with
quote-aware detection so a # inside quotes is never a comment. +31

Only lowercase-hex 8-4-4-4-12 folder names are lane/card candidates;
anything else is a stray — skipped with a distinct warning, never

Design resolution from the Redesign board. +5 tests.
Claude-Session: https://claude.ai/code/session_018BjQRYBR6jQja3jCRi5S3A
Resolves 03's internal conflict: the shown trash consumes one fixed
width unit (no width frontmatter, not resizable) and Show/Hide Trash
joins the re-divide trigger list — lane units + 1 while shown. Small
windows compress like any lane add.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Resolves 03 ▸ Motion's self-conflict: narrow keys are the sole-selected
card, the search query, and the drag's drop proposal (reflow-to-make-
room animates under it); animation-free means the replica and marquee's
1:1 cursor tracking and multi-select churn, not reflow.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Fixes 05's rationale: a cross-board move keeps its UUID (remint is
collision-only); the listing starts fresh because the destination repo
has no commits for the arriving folder.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Resolves the 01-vs-09/03 contradiction: Save as Template and File ▸
Duplicate copy the board folder as-is, GUIDs kept — the remint rule
governs item-level copies inside an existing board. Duplicate's
fork-keeps-history guarantee requires retention (copied .git history
must keep naming real paths); 03's Duplicate paragraph now says so.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Resolves the 01-vs-06 contradiction: the pure-diff composer cannot emit
'Renumber lane X' (order-only bookkeeping composes nothing), and a
renumber never happens alone — it batches with the insert/move that
exhausted the midpoint, so the commit reads as that event. 06's
bookkeeping rule now says sequence-preserving order changes are the
bookkeeping; repositioning order changes still compose Reorder.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Resolves the 02-vs-04 contradiction: foreign edits that flip deleted:
on a selected card eject it from the selection (and pending cut, which
already behaved this way), so 04's homogeneous-by-liveness invariant
holds across reloads and menu validation never sees a mixed selection.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Resolves the 06-vs-08 contradiction: 06's Lanework External fallback
demotes on true deletions only (id vanished from the board, per the
message engine's whole-board id matching), not folder moves. A bare mv
leaves the moved card unstamped, so 08 now teaches re-stamping on every
move as well as every write.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Resolves the 02-vs-04 search-filter contradiction: 04's live predicate
wins. 02's frozen-UUID transient-state list drops the result set; the
query is transient, the result set recomputes against each snapshot.

Pure tree walk: root → lanes → cards, level is position. Fail-fast with
path+reason for bad YAML, missing/malformed schema or order, newer

Immutable snapshot value types encoding the frontmatter tables: ItemID
wraps the exact folder name (not Foundation UUID, which uppercases);
lanes/cards carry FieldValue-typed fields, display-ordered children
including flagged tombstones, and their full FrontmatterDocument so
unknown and reserved keys ride along uninterpreted. Boards are
identified by rootURL — package folders are human-named, not UUIDs.
