Phase 3 of the decision surface, completing the card (01 ▸ Malformed
input, settled 2026-07-31). An attended open's fail-fast walk transforms
the loading window's content into one aggregated surface — never a
sheet, never a chain: defects grouped by class, each class stated once
with its files listed (Reveal in Finder + Open in Editor per row), a
class-level default preselected, per-item override behind a disclosure.
Only honest choices: YAML and malformed-schema get Editor + Re-check
(Skip below the root); newer-than-app gets Skip alone and blocks the
board at the root; the two root repairs — minted index, schema: 1 stamp
— are defaults. Repair and Open applies fixes in one store-less write
bracket and re-walks: clean proceeds, remainder re-aggregates into the
same surface. Cancel and ⌘W retire to welcome's row; restored opens
never see the surface at all (OpenOrigin rides the PendingOpen carrier).
Skips are per-open consent that rides the session — the store retains
the skip set and every reload passes it — and the opened board posts a
warning-tone notice naming what was left out, each item's Reveal riding
the banner strip's new reveal control. On Pro boards the repair bracket
binds its own EchoLedger, heal-marks everything, and the store adopts it
before the committer starts, so repairs land as one separate commit
authored Lanework Integrity — pinned end to end. Also fixed en route: a
retired loading window left its close interception installed and
returned false from windowShouldClose forever, blocking quit.

Phase 2 of the decision surface: the pre-snapshot loading state ruled
2026-07-29 (02 § Launch and window lifecycle), built. The board window
appears immediately at its saved frame, titled with the registry
record's cached name, its content a centered spinner behind an
injectable ~200ms grace — no skeletons, and the first snapshot snaps in
place. The tree walk runs off-main via BoardStoreRegistry.acquireOffMain
(per-board single-flight keyed by file identity — concurrent opens of
one root share a walk, restoration of many boards is genuinely
parallel), landing in BoardStore's new designated init(rootURL:loaded:);
the self-walking init survives as a convenience for its ~470 callers.
⌘W during the walk is real: configureWindow split into a loading half
(frame restore, frame tracking, close interception — installed before
the walk) and a store half (toolbar, widget, hideTitle, undo — installed
at the snap), and the walk lives in an explicitly held BoardOpenWalk so
the user's close and SwiftUI's teardown end in one cancel().
Cancellation is discard-on-completion: nil from acquireOffMain means
nothing was built, nothing retained, and no open-now flag was ever set.
Failure keeps today's sequence exactly: record the launch failure,
welcome's row carries it, the window retires.

Phase 1 of the decision surface (01 ▸ Malformed input, settled
2026-07-31): BoardLoadFailure aggregates the walk's defects in walk
order — stop-at-first retires. Environmental failures (unreadable root,
not-a-directory) stay immediate single-defect throws: there is no walk
to collect from. A defective root index is recorded and the walk
continues into the children (nothing in the walk consults the parsed
root document — verified); a defective lane, card, or trash-entry index
records and skips its subtree, Re-check's whole-walk re-aggregation
being the designed loop for what hides beneath. load(skipping:) is the
per-open skip channel: a skipped path's item is omitted from the model
and surfaces as LoadWarning.userSkipped; root paths are unskippable by
construction. The reload-breakage banner carries the aggregate ("…and
N more"), single-defect sentences byte-identical to before. Two new
multi-defect fixture boards; suite 2591 green.

The 2026-07-29 integrity design pass, consolidated (DESIGN/01 -
Validation and healing; DESIGN/02 - Components): IntegrityRules
(Storage, pure) is the one home for the identity predicate and
canonical form (BoardWriter.canonicalIdentity deleted, ItemID and the
loader forward to it), the per-field rulebook, uneditable shapes,
per-kind index validation, the reserved-name tables, and the trash
kind discriminator (values trusted - kind: lane/card explicit,
unrecognized falls to shape). LoadResult's ad-hoc channels fold into
one typed Defect stream (looseCardFiles / legacyTombstone /
claimedNameSquatted, per-defect heal signatures); the old accessors
survive as computed views.
HealScheduler (LiveStore) states the six-step heal pattern once -
resting-clear, lock gate, isWritableFile gate (now covering all four
heals), signature memo armed-before-attempt with explicit
clear-on-success, disk re-verify in each write half, one banner-posture
table (BannerCenter keeps all phrasing). The three hand-rolled healers
run on it with behavior preserved - including the
relocation-notice-despite-partial-failure quirk, deliberately. Heals
run at the reload tail AND at registry acquire, closing the
migration-never-fires-at-open asymmetry. Displacement runs first: a
squatted .trash would otherwise fail the migration and arm its memo
against an unchanged picture.
Claimed-name squatters (ruled today, 62c47a2) displace by the shared
Finder-style rename ladder - preserved verbatim, symlinks moved as
links, nothing stamped; AgentGuide's untouchable-skip upgrades to
displace-then-write, the CLAUDE.user.md-taken skip stands. kind stamps
on every create and backfills on any index rewrite via the on-touch
seam (placement resolver stamps nothing when the parent is unknown -
a guessed kind is worse than an absent one; board-root writers declare
theirs). Heal writes mark their EchoLedger receipts (inert in base;
pro-m1's committer will split them into their own commits). The
renumber ask-renumber-ask-again two-step is one shared helper, adopted
at all nine call sites.
69 tests added. 1738 green on both schemes.

Closes the gap found at m10: enterUnwritableLock existed with zero call
sites. WritabilityProbe classifies the cause volume-first - a board on a
read-only DMG is also permission-denied by access(2), and "you don't
have permission" would send the user to a Get Info panel that cannot
help - with a pure classify(volumeIsReadOnly:isWritable:) truth table
and a two-syscall probe that rebuilds its URL to defeat NSURL resource
caching. ReadOnlyLockReason.unwritableLocation now carries the cause;
BannerCenter phrases the two ("this board's volume is read-only" vs
"you don't have permission to change this folder").
The probe wires once in BoardStoreRegistry.acquire, immediately after
the store loads - every open path funnels through it, and running
before the loose-file relocation and agent-guide hooks makes the
skipped-with-log guide write true by construction (its isWritableFile
pre-check demotes to second line of defense). The board still opens:
lock, not refusal.
The reconciling re-probe is now symmetric per 02's settled text - a
volume gone read-only mid-session raises the lock at the next probe
(sibling locks settle first, so a root returning read-only lands the
honest lock); the stale "deliberately one-way" comment and its pinning
test are gone. Save as Template's carve-out predicate extracted to a
testable allowsSave (behavior unchanged); Duplicate stays disabled.
11 tests added. 1649 green on both schemes.

The app-owned agent guide at every board root (DESIGN/08 ▸ The agent
guide): version-gated by a first-line marker (v5, superseding the
pathfinder's v4 guides on real boards), rewritten when missing or older,
byte-for-byte untouched when current or newer. A markerless CLAUDE.md is
displaced to CLAUDE.user.md when that name is free — never clobbered —
and the guide write is skipped with a log when it isn't. Symlinks,
folders, and read-only volumes are skipped in silence; the write rides
performWrite's bracket as an app-mediated Writer operation (new
WriteOperation.agentGuide), so the echo lands appMediated and the
Pro-era committer can attribute it honestly later.
Hooked at store acquire (beside the loose-file relocation, after the
watcher exists) and on every successful reload — the guide self-heals
from foreign deletion or rollback, pre-wiring 06's acknowledged undo
bounce. The refresh memo arms before each attempt and clears on a
successful write, so a failing write can't hot-loop and a foreign
deletion stays healable. First-line-only marker parsing (no Regex);
guide content is one swappable literal, finalized under the next 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.

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.

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.
