The tombstone model is retired wholesale: deletion is a move into the reserved
<root>/.trash/, always entering at the top (rank minting — no deleted: key, no
timestamp sort), with modified stamped for the future age-based purge. Lanes
are never trashed — lane delete is physical, native undo in-session the net.
Put Back is gone: restore is drag-out or cut+paste (⌘X now enabled in the
trash as the keyboard restore path). Trash cards are ordinary cards — search,
selection, clipboard, and rendering uniform — and one container boundary
replaces the effective-liveness, ancestor-walk, and kind-homogeneity machinery
across 02 and 04. Delete stages by place (board moves, trash deletes
permanently under the recoverability confirm); legacy deleted: keys migrate
without destroying (cards relocate, lanes return live, notices). Templates
exclude .trash; Duplicate carries it; the agent guide teaches delete-as-move.
Materialized reserved lanes are named as a pattern — .archive is WISHLIST #8,
and the backed-out release-presentation question is marked open in 03.
Ruling: Redesign board Resolved card e8f1a6c2; 19 mooted tombstone-era rulings
moved to the board's new Mooted lane.
Claude-Session: https://claude.ai/code/session_01CqjXB7ASoWtbyoGod68k97
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media story (03, 01, 10, 11; the same-day carousel settlements superseded on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).
Claude-Session: https://claude.ai/code/session_01CqjXB7ASoWtbyoGod68k97
Edition split follow-through: 12-editions.md and 13-native-undo.md join the
corpus; git-era docs (06, 07) are Pro-scoped and cross-references realigned.
Resolution session rulings written in place: caret chords yield to any focused
text control (04, 11); the drop settle holds its proposal as overlay state and
02 gains the overlays family; Duplicate gets the save-panel fallback and a
cancellable copy walk (03); Finder open is a standard document open (02);
failed first opens record before loading with the folder name provisional (02);
trash pointer ranges skip by kind, full-height marquee surface, Select All by
kind, rows-only trashed universe (02, 04); Empty Trash counts entries (03);
create handoff reads as one arrival (02); range-anchor lifecycle, board-
background click grammar, jump landing cards, lane-domain shift-arrows (04);
Reduce Motion restated per voice (10).
Claude-Session: https://claude.ai/code/session_01CqjXB7ASoWtbyoGod68k97
- 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
- README: pathfinder path corrected to ../../Kanban
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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
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
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
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.
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
- 10 cites 11 for Add Attachment and the lane-width menu items
- 04 uses ⌘/⇧ symbols for click modifiers; card moves scoped to the
⌥⌘ chord; ../WISHLIST.md path fixed
- 03 says stepper (plus the menu pair) in the editing-surfaces table
- 06 says one commit per debounce window
- 03/10 Reduce Motion lists aligned at five items; rubber-band
disambiguated as the lane-resize feedback
- 11 requires the trash shown for Empty Trash
- 02 rewords and-peers
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
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.
Claude-Session: https://claude.ai/code/session_01HJ7PhFNmQ19bvy9RMD6GSb
Resolves the 09-vs-03 contradiction: the principle is never-init-
unasked, scoped to template instantiation; File ▸ Duplicate carries
.git deliberately as a history fork.
