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

Phase 1 of the trash pivot: the file format learns .trash/. The loader
parses the reserved root container — cards only, one shared parseCard
for both containers so fail-fast, attachments, and verbatim documents
are literally the same code; absent means empty; symlinks and
lane-shaped nestings fall out as strays by construction. BoardModel
grows snapshot.trash as a plain rank-ordered card list — the container
has no identity to carry. Legacy deleted: keys keep flowing through
the retiring flag path so every tombstone consumer stays green, and
are additionally reported through LoadResult.legacyTombstones in the
loose-file idiom for phase 2's migration scheduling — nothing vanishes
from view before its folder has actually moved, which is also 01's
lock-deferral posture. Writer primitives land value-passing: move to
trash with caller-minted rank and the deliberate modified stamp,
tombstone migrations that surgically remove the key, physical lane
removal, per-card and whole-container purge that leaves strays
verbatim, and byte-faithful whole-subtree capture/recreate for lane
undo. Board-wide identity now spans the trash, so an import colliding
with a trashed UUID remints instead of colliding. The watcher already
delivered .trash events — isGitInternal tests a component, not a dot —
now stated and pinned rather than relied on.

The escape hatch: View > Raw Source (opt-cmd-E) unmounts the whole
content area for the literal on-disk index.md in a plain monospaced
editor with Cancel/Apply. Raw source is window-level state, not a third
body mode — entry rides setMode(.preview), which flushes the Edit
session by construction, then reads the file fresh; exit reveals
Preview, and an empty body after Apply does not reopen Edit (openIfNeeded
already ran). Apply validates the proposed bytes through the loader's
own card checks — parseDocument's strict UTF-8/BOM rejection, schema,
order — deliberately skipping the uneditable-shape refusal, since a
flow-mapping card is exactly what the hatch repairs; invalid bytes
alert in place with the loader's own error and no bracket opens. The
write is byte-for-byte with no modified stamp and no modified-by clear,
per 01's explicit carve-out — the verbatim contract outranks stamping —
and identical bytes write nothing. Escape cancels, cmd-Return applies,
toggle-off applies too, and cmd-E disables while raw is active via a
testable predicate. Tombstoned targets refuse as vanished: a foreign
delete is never reverted by a stale buffer.

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.

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.

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.

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.
Full suite 342 tests in 63 suites green. Two findings filed.

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.

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
descended, never able to fail-fast a load. UUID-shaped folders keep the
prior contract (missing index skips, malformed frontmatter fail-fasts).
Design resolution from the Redesign board. +5 tests.
